Patent GB-596865-A (GB)
Title: Cabin pressure control
IPC: B64D13/04
Filed: 1945-01-04
Abstract: 596,865. Automatic control systems. GARRETT CORPORATION. Jan. 4, 1945, No. 390. Convention date, Dec. 13, 1943. [Class 38 (iv)] In an automatic aircraft cabin pressure control system, means respontive to cabin pressure to maintain cabin pressure constant, and means responsive to the difference between cabin pressure and ambient pressure to maintain that difference constant, are selectively rendered effectve by means responsive to ambient pressure. In Fig. 1, air is drawn into an aircraft cabin 11 by a blower 12 and the pressure within the cabin is automatically regulated by control of a reversible electric servomotor 20 operating, through gearing, an exhaust air valve 16. For altitudes up to a predetermined value, e.g. 10,000 ft., this valve is fully open and the pressure within the cabin is the same as the ambient pressure. Above this predetermined altitude and up to a second predetermined altitude, e.g. 30,000 ft., an aneroid bellows 26 responsive to absolute pressure within the cabin operates a contact 66 co-operating with opposed contacts 56 and 57 to selectively energize fields 22 or 23 of motor 20 so that valve 16 is automatically adjusted to maintain cabin pressure constant. A second aneroid bellows 82 responsive to absolute ambient pressure operates contact 90 at the second predetermined altitude so that the supply from a battery 95 to motor 20 is no longer dependent on contact 66 but is dependent on contact 70. Contact 70 is operated by a third aneroid bellows 30, responsive to the difference between cabin pressure and ambient pressure, and selectively controls motor 20 through opposed contacts 61 and 62 to maintain this pressure difference constant above the second predetermined altitude. The second predetermined altitude is preset manually by a screw 93 adjusting the position of contact 90 and its co-operating contacts relative to bellows 82. To minimise hunting, engagement between contacts 66, 70 and the contacts with which they co-operate is made intermittent by reciprocation of the latter through cams 105, 106 driven by a motor 108. Specification 521,623, [Group XXIX], is referred to.

[Class 103 (i).] Brake mechanism for rail vehicles comprises on each side of the vehicle, brake shoes engaging the outer sides of the wheels and connected by an equalizing linkage, the two linkages being entirely or substantially mechanically independent and being operable alternatively by hand or fluid pressure. The mechanism on one side of the vehicle comprises brake shoe rods 1, 2 connected to levers 5, 6 connected by a rod 13 which is suspended from the frame by link 14. A hand-operated rod 15 and a cylinder 10 are connected to the lever 5. The mechanism on the other side of the vehicle is the same except that it is turned end for end, the rod 15 extending to the other end of the car. The shoes at each end may be connected by a light transverse beam to which the rods 1, 2 are attached. Hand operation thus applies the shoes mainly on one side of the vehicle but the cylinders 10 are connected to a common source so that the shoes on the two sides are applied equally by the fluid-pressure. The leverage of the levers 5, 6 is arranged to apply greater pressure to the front wheels. According to the Provisional Specification, the two levers 5 may be connected by a sway-bar to which a single cylinder and the two hand operating-members are connected.

Title: Single or multi pole push button actuated excess current switch having thermal and or electromagnetic trip
IPC: H01H75/08
Filed: 1972-01-06
Abstract: 1320474 Automatic circuit-breakers ELLENBERGER & POENSGEN GmbH 6 Jan 1972 [13 May 1971] 587/72 Heading H1N A push-button circuit-breaker has a bridging contact 18 connected to the push-button 39 by a toggle 20, 24 having pivot pins 19, 25 guided in grooves 27, 26 in the housing 1 and a toggle joint formed by a pin and slot connection 22, 23 with a spring 57 tending to bias the levers apart. When the circuit-breaker is being closed the pin 19 abuts a shoulder 28 in the groove 27 until a projection 55 on the toggle lever 20 engages a stop 56 formed in the housing, so that as the toggle is straightened the pin 19 is caused to slide off the shoulder 28 and the spring 57 snaps the contacts closed and thereafter provides the contact pressure. The contacts are held closed by a pivoted latch lever 30 which engages the pivot 25 of the toggle lever 24, this lever having an arm 49 which is latched by a trip lever 48. In the event of excess current conditions a thermal and/or electromagnetic tripping device turns a shaft 47 causing the lever 48 to release the lever 24 so that the toggle collapses under the pull of a spring 33 opening the contacts 15, 17, 16. A spring 43 moves the push-button 39 out to its open position and through a link 61 straightens the toggle to reset the circuit-breaker for a subsequent closing operation. The tripping device is arranged in a separate compartment in the housing and may comprise a U-shaped bimetallic strip through which the current flows so that electrodynamic forces cause the free limb of the strip to bend in the tripping direction. This limb acts through a push-rod on an ambient temperature compensating strip secured to the shaft 47, Fig. 2 (not shown). Three circuit-breakers may be secured together to form a multi-pole unit, only the central circuit-breaker having a push-button and the shafts 47 and the pins 25 being interconnected, Figs. 5 and 6 (not shown).

Abstract: 933,069. Weighing apparatus fitted to lift trucks. STREETER-AMET CO. Jan. 9, 1962 [Oct. 2, 1961], No. 840/62. Class 143. Weighing apparatus, particularly for use with fork lift trucks, comprises two interconnected, horizontally spaced, vertical members 12, 13 which are vertically displaceable with respect to one another, the displacement being used to indicate the weight. The member 12 is adapted by means of lugs 14, 15 to be mounted on the mounting plate of a fork lift truck and the member 13 has a notched ridge 17 along its upper edge on which the upper ends of the forks are hooked, the lower ends being secured to the lower edge. The plates 12, 13 are connected by rectangular beam members 18, cut out in their centre portions to leave resilient beams 23 which flex to allow relative vertical movement between the members 12, 13. Lugs 24, 32 project from the member 12 and lugs 26, 29 project from the member 13 and these lugs have aligned holes in which guide pins fit loosely to limit relative horizontal movement of the members 12, 13. A lug 33 projects from the member 12 and carries a load cell 34 and a lug 35 projects from the member 13 and is threaded for a screw 36 which engages the load cell. The load cell 34 is at a neutral position between the plates so that slight rocking does not side load the cell. The screw 36 is adjusted to give a slight pre-load on the cell when there is no load on the forks. A screw plug 28 in the lug 26 is removable for access to the screw 36, which is locked in adjusted position by screws 37. The arrangement is duplicated for a fork lift truck, the members 13 being interconnected by cross-beams 11 which fit loosely to obviate binding if one fork is loaded more heavily. The load cells of the two units are connected in a circuit so that their outputs will be added to provide an indication of the total load.
