Abstract: 1,161,735. Door hold-open device. ATWOOD VACUUM MACHINE CO. 5 Oct., 1966 [27 Nov., 1965], No. 50503/65. Heading E2F. A hold-open device for motor vehicle doors comprises a bracket 10 for mounting on the door 11 of a motor vehicle, a C-shaped high carbon steel torsion bar 15 mounted on the bracket 10 in a preloaded condition and having a laterally extending arm 18 on which is formed a detent 19, which is received in an elongated slot 20 in the bracket 10. A flat hold-open arm 12 pivoted at 25 to the bracket 13 of a door pillar 14, is formed with an elongated guide slot 27 which receives a roller 28 mounted at the end 22 of the torsion bar 15. The free end 29 of the pivot blade 12 is doubled back and carries a striker in the form of a serrated roller 30. When the door is opened, the roller 28 slides along the slot 27 and guides the pivot blade 12 until, in the fully open position, the serrated roller 30 engages and is held by the torsion bar detent 19. The roller 28 is then at the end 32 of the slot 27, which serves as a door stop. A second striker may be provided on the hold-open arm to give an intermediate hold-open position. In a modification (Figures 3, 4 and 5, not shown), the pivot blade 121 is formed with an arcuate guide slot 27', the striker roller 30' is carried on a rivet 31' on the blade 12' and is arranged to cooperate with the detent 19' of the torsion bar 15' at the fully open position.

Abstract: 1485807 Burning nitrogenous waste EXXON RESEARCH & ENG CO 22 Nov 1974 [28 Dec 1973] 50634/74 Heading F4B Nitrogenous non-gaseous material is pyrolized in a fluid bed with a nitrogen oxide reducing catalyst, and the products of partial oxidation and decomposition may be burnt immediately with additional oxygen or may be collected for use elsewhere. The nitrogenous material may be an explosive or propellant, oil slick or low sulphur coal. An aqueous slurry of T.N.T. or other explosive or propellant is fed from a stirred tank 22 to a bed of finely ground catalytic material through a line 14; air, which may be preheated, is fed below the distributer plate 11 and auxiliary fuel, e.g. propane, natural gas or oil is fed to the bed at 15. The quantity of air fed below the bed is controlled to maintain a reducing atmosphere in the lower part of the fluidized bed. Additional air is supplied at 18 below the surface of the exanded bed so that the gases formed are completely oxidized. The burnt gases are fed to a cyclone 28 to extract any fine catalyst particles which may be carried over, and return them to the bed. The catalyst may be nickel in an alumina base, nickel nitrate in aqueous solution fed in with the slurry, or metallic iron, copper or cobalt or the oxides or catalytically active salts of these metals or a noble metal such as platinum.

Abstract: 1,142,678. Valves. AMERCON CORP. 11 Nov., 1966 [24 Nov., 1965], No. 50671/66. Heading F2V. The pressure reducing valve is of the kind in which a valve member 8 between the inlet 1 and outlet 2 is connected to a loaded diaphragm 4 which is responsive to the outlet pressure. In order to compensate for variations in inlet pressure, either the seat member 3 is made responsive to this pressure so as to tend to restrict the flow opening 10 if the inlet pressure increases; or alternatively the valve member is made responsive to the pressure in the seat opening so as to move it independently of the diaphragm 4 in the direction toward the seat if the inlet pressure increases. As shown, the seat member is movable against a spring 20 by the inlet pressure. In an alternative arrangement, the valve member (29, 31), Fig. 3 (not shown) constitutes a piston mounted in a cylinder (27) connected to the diaphragm. Pressure is admitted behind the piston which moves against a spring (36). In a modification the valve member is connected directly to the diaphragm, Fig. 4 (not shown).

Title: Stabilization Control System
IPC: G05D3/12
Filed: 1966-11-14
Abstract: 1,170,585. Automatic attitude control. GENERAL ELECTRIC CO. Nov.14, 1966 [Jan. 21, 1966], No. 50948/66. Heading G3R. The angular position of a platform about axis is automatically stabilized by means of a geared down reversible D.C. motor of low effective inertia controlled through a width modulated pulse amplifier by feedback signals dependent on platform movement and motor current. In Fig. 3, the attitude of a platform 10 is stabilized about its elevation axis by a reversible D.C. servomotor 12 adjusting the platform through reduction gearing 14. The inertia and speed of the servomotor and the gearing ratio are chosen so that the effective inertia of the drive is small compared with the inertia of the platform and its load. Deviations of the platform are detected by a torqued rate gyro 16 on the platform producing D.C. signals which are applied to an integrating memory amplifier 28 together with signals which select the attitude to be maintained. Amplifier 28 controls motor 12 through further D.C. amplifiers 58, 58a and a solid-state switching amplifier 22. Amplifier 58a is modified to have a suitable frequency response and a filter 64 eliminates unwanted frequency components from the control signals. Amplifier 22 is switched at a frequency determined by an applied signal 76. Feedback in dependence on motor current is applied through a D.C. amplifier 42 and resistance-capacity network 46, and motor current is prevented from exceeding a predetermined limit by Zener diodes 50, 52, associated with the input of amplifier 58a, which are rendered conductive at a predetermined output of amplifier 42. Deviation and speed of the platform are limited by Zener diodes (not shown) which are rendered conductive to stop the servomotor when the signal produced by a potentiometer or tachometer driven by the servomotor exceeds a predetermined value. A similar system is provided to stabilize the attitude of the platform about a perpendicular transverse axis.

A switch with automatic pneumatically delayed switch-off has a housing 1 containing a bellows 2 joined at one end to an actuating slide 3. When slide 3 is pulled out by handle 4, bellows 2 is expanded, and to equalize the air pressure, air is let in through valve 5 operated by depressing button 6. Pulling out slide 3 also tensions compression spring 15, and moves a driving member 9 on slide 3 to contact surface 11<SP>11</SP> on a member 11 carrying contact bridge 10 to drive member 11 against the action of compression spring 17 to force cam 19 on member 11 over a locking member formed by leaf spring 12 so that member 12 springs into recess 21. Moving member 11 also bridges contacts 13, 14. The resetting of the switch is caused by compression spring 15 acting to compress bellows 2, the rate at which bellows 2 is compressed being determined by a valve 16 which lets the air out at a preset rate. As slide 3 moves back, member 9 moves till it contacts surface 11<SP>1</SP> on member 11. When it has applied sufficient pressure to surface 11<SP>1</SP> to overcome spring 12, member 11 is suddenly released and slid to its inoperative position, breaking the contacts by spring 17.
