Butt hinges These are available in pressed steel, cast steel, brass and cast brass in sizes ranging from 50mm to 100mm, for fitting internal or external doors and wardrobe or cupboard doors (but not fire doors).
Rising butt hinges Sometimes it is useful if a door raises itself as it opens so that it can clear things like carpets. Rising butt hinges are designed to do this. They are usually made from cast steel, in right- and left-handed sets. The top end of the hinge pin is open-ended, and as long as the hinge is fixed on to the frame with the knuckle (or the pin) clear of the frame, the door can be removed by lifting it off the pins.
Rising butt hinges are fixed in a manner similar to that described for butt hinges. But the following addi¬tional points should be considered:
• doors fitted with this type of hinge tend to be self-closing owing to the weight of the door on the spiral seat¬ing of the hinge • the hinges must be accurately located on the door and the frame, otherwise only one hinge may be resting on its spiral seating - fit one hinge and then the other. • to allow the door to close without catching the frame, the top corner of the door must be tapered.
T-hinges These hinges are made from steel and galvanised or japan¬ned to protect them from corrosion. They are lightly built and suitable for use on ledged-and-braced doors and gates. Framed, ledged-and-braced doors may be hung on T-hinges or on standard butt hinges.
Strap hinges These are sturdier than T-hinges and are ideal for garage doors and large heavy gates. This sort of hinge is held in place by screws and a coach bolt. It has an open pin so the door can be removed from the frame - by taking off the upper pin cup - without having to unfasten the hinge from the door.
Door furniture Doors need something for you to open and close them with - usually a handle of some sort - and some¬thing to keep them in the closed position once they have been shut. On external doors the retaining device is usually a lock. On internal doors, including cupboard and wardrobe doors, a number of dif¬ferent devices can be used
Ball catches These are basically a casing containing a spring-loaded ball or roller which holds the door closed when it engages with a strik¬ing plate (keep) in the door frame. They are simple to fix - insert the catch into a prebored hole in the door and hold it in position with screws.
Spring latches These hold a door more firmly than ball catches. To open the spring latch a lever handle or knob is required.
Lever handles These are used to open latches fixed in doors. They work by rotating a square metal spin¬dle which passes through the door and the latch. Lever handles come in a variety of shapes and finishes -including anodised aluminium and brass.
Thumb latches These are the tradi¬tional latches for ledged-and-braced doors and garden gates.
I have a 2001 Nissan Altima GXE and don't have the anchors other cars do. Do Nissan Altima's have these anchors anf id so, where do I find them?
LATCH anchors can not be retrofitted in any car. They must come installed by the factory. 2003 and newer vehicles have them - very few 2002 (mostly luxury models do) or earlier vehicles do. It was required as of 2002, so that means model year 2003. You can get the tether anchor (goes in the back dash) installed. The hole is already drilled, you just need an inexpensive tether anchor kit to install it.
also, its worth noting that you do not have to have LATCH in your vehicle to use car seats in it. Seatbelts are just as safe as LATCH. LATCH was invented to be convenient and universal, though it frequently fails on both counts b/c of variances between vehicle and car seat manufacturers. You also can not use LATCH in the middle position. I would definitely get the tether anchor installed, as it does significantly raise the protection a seat offers, but LATCH is not a big deal. Just use the seatbelts.
A vehicle seat back mounting having a latch pivotably mounted for a limited swinging movement with a recessed catch shaped for engaging a projection on the stationary bus seats part to prevent forward tilting. The center of gravity of the latch is located laterally and below the pivot point so that during manual tilting of the seat back the force of gravity releases the latch from the projection; and so that during sudden deceleration of the vehicle an inertial force counteracts the force of gravity and prevents unlatching.

Bus seatsof various constructions are already known, as are hinges of different constructions which mount the rear component of the vehicle seat on the rear region of the seat component of the seat for tilting at least frontwardly from atleast one erect position to a frontwardly collapsed position and back. Then, it is also known to equip the hinges of the hinge arrangement with a fine-adjustment arrangement which enables the user of the bus seats to select an erect position which is mostcomfortable or convenient to the user.

Why isn't parachuting a part of the safety regime when traveling by plane?
When I look at the news and see where planes are just falling out of the sky and multiple lives have been lost, I feel very upset about the entire situation. Airplanes provide flotation devices, oxygen masks, and other safety mechanisms for passenger and staff safety, but why aren't parachutes also provided for safely exiting a plane in emergency situations? Is it because there isn't enough time? Or is it because of the latch on the doors or that television/movie disaster I saw that shows planes imploding when doors are opened? I'm really curious about this.
It is a tempting idea....but:
First of all, news reports on airplanes emphasize crashes because they are dramatic. However, planes do not fall out of the sky all of the time. Every year, more than 100 people die each and every single day in car crashes - just in the US alone. By contrast, over the past dozen years or so, the average number of people who died in an accident on a US carrier is 95 per YEAR. 100 deaths per day in cars vs. fewer than 100 per year in planes. Pretty safe.
Second: outfitting everyone with a parachute would be incredibly expensive, add enormous weight to the plane (which would require more fuel, pollute the air more, make ticket prices go up etc, etc.).
Maintenance on those chutes would be very high because some jerk is going to pull the rip cord just for fun sometime and the chute would been to be repacked. You might actually need to repack them every day because there are some idiots who would try to sabotage the chute "just for fun". What kind of liability would the airline face if people actually were able to evacuate with the chutes, and someone's did not work?
People who have no training in jumps could very easily be injured on landing, or when leaving the plane. Who is going to carry the children and babies, the elderly and so on...?
In order to be useful in an emergency, everyone would have to be wearing their chute at all times. I have never worn one, but I think that most people would find them uncomfortable for even short periods of time. Probably hard to wear one modestly with a skirt or dress.
Finally - most accidents occur at or near takeoff and landing when the plane is way too close to the ground to make a chute useful for any except the first few people who exited. And accidents at altitude are often catastrophic, so there would be no time to get out anyway.
Some months back someone posted a whole series of statements on Y!A (not really questions) advocating ejection seats on all airplanes - kind of got the same response - not at all a practical thing to do.
However - it is perfectly OK to carry your own parachute onto a plane.
Car Seat Safety : How the LATCH System Works on Car Seats
Where can I install a safety latch for a car seat on a 97 Saturn SL1?
Do I simply find a spot and drill through the frame or does this model has designated holes in the frame for this purpose? If so, where are there holes and how do I find them?
for front facing it needs a rear tether anchor installed. I know the anchor needs to be drilled into the frame of the car. I'm only asking where to perform this drilling.
The hole in the frame is already there - its the hole through the car interior that will need to be put in if it is not already there. Check out the deck of the rear windshield. See any little round plastic circles anywhere? Try and pull one out if you see one, that's how they frequently cover up the tether anchor holes. This is NOT something you want to do yourself if the hole isn't already there. B/c if you put it in the wrong spot, it will not secure the child's seat. Go to the dealer - it is not an expensive thing to have done.
Also, post your question at http://www.car-seat.org there are car seat techs there who have access to the LATCH manuals and could tell you exactly where your tether anchors are located.
