Title: Improvements in or relating to high lift safety valves for steam boilers
IPC: F16K17/08
Filed: 1938-04-05
Abstract: 492,878. Safety valves. KNORRBREMSE AKT.-GES. April 5, 1938, No. 10404. Convention date, April 12, 1937. [Class 135] In a high-lift safety valve of the kind in which the pressure in a huddling chamber a above the valve seat is opposed by the pressure in a counter chamber d to which steam is normally admitted when the valve opens, as well as by the loading spring m, a controlling device c is provided which delays the filling of the counter pressure chamber d until the pressure in the huddling chamber a and hence the boiler pressure has fallen to the desired value. The device c has a spring-closed valve e in the pipe connection v, f between the chambers a, d. When the safety valve opens initially, the pressure in the huddling chamber a has access through the pipe b to a chamber k containing a spring-loaded diaphragm or bellows h which is thereby raised from the control valve e so that the latter closes. The loading spring i is stronger than the valve spring g, but to accelerate the opening of the control valve, the interior or upper side of the bellows or diaphragm is connected by a branch l to the pipe f and is hence subject to the pressure in the counter chamber immediately the valve e opens. The chamber k may have a vent n.

Title: Restraint system for vehicle occupants
IPC: B60R21/00
Filed: 1973-03-03
Abstract: 1427564 Safety vehicle seat N HAMY 15 March 1974 [3 March 2973] 10459/73 Heading A4J [Also in Division B7]  A hollow restraint arm contains a belt which can be tensioned to make a segmented part of the arm bend to a restraining position in which it embraces part of the seat occupant's body.  As illustrated, four such arms 16, 16', 18, 18 are associated with a seat 14. In their inoperative position, Fig. 4, the arms are held extended by springs attached to their outer surfaces, Figs. 12- 15 (not shown). The arms are bent to their operative positions, Fig. 1, by a motor 36 which turns reels 44, 44', 54, 54 to tighten the belts within the arms. The motor 36 can also act via pulleys 68, 70 and a cable 72 to move the upper pair of arms to the correct position along a guide 74. The belts may be tensioned in response to actuation of a seat switch by the weight of the occupant's body. However, belt tensioning may additionally depend upon some other circumstance so that, for example, the occupant will not be restrained until the vehicle-is operating. Sensors on the ends of the arms discontinue tensioning when the ends come into contact with the occupant's body. After the belts have been tensioned, the occupant retains some freedom of movement since the seat back pivots relative to the remainder of the seat. The seat back is linked by a belt 66 to an inertia rod 64 which, in the event of a collision, limits forward movement of the seat back. The restraint arms may be suitably padded. In the case of the free end of an upper arm 18, 18', the padding may include a chamber located on the inner side of the arm and containing air or other fluid, Figs. 10 and 11 (not shown). In the event of a collision, the pressure of the occupant against the arm forces the air through a valve to inflate a further chamber located on the upper side of the arm to protect the occupant's head.
