Title: An electric circuit breaker
Inventor: WRIGHT BARRY THOMAS
IPC: H01H73/50
Filed: 1982-12-22
Abstract: In a miniature electric circuit breaker, the electromagnetic device which, on passage of a short circuit current, initiates the tripping operation, comprises a stationary yoke 11 with a planar surface and an associated conductor 16 inter-connected between the breaker terminals, a flat magnetisable flapper armature 25 pivotable about an axis parallel to the conductor between a first position and a second position in which it is inter-facial contact with the planar surface of the yoke, a spring 26 urging the flapper to the first position, and a trip mechanism 27, 28 operatively coupled to the flapper. On passage of a short circuit current, magnetisation of the yoke 11 causes the flapper armature 25 to pivot against the action of the spring 26 into inter-facial contact with the yoke and thereby to effect disengagement of the trip mechanism 27, 28 and initiate operation of the breaker. <IMAGE>

Title: Electrical equipment safety
Inventor: HEMINGWAY THOMAS KEITH
IPC: G01R19/145
Filed: 1983-02-22
Abstract: Hazardous and/or inconvenient residual potentials may be retained for a time after the power to equipment is switched-off, such as in a power-supply comprising a storage capacitor. The provision of an on-off switch 1 which, when off, makes a resistive discharge path 5 for the capacitor 3 may partially alleviate the hazard. Herein, a safety device is provided which at times when a residual charge (but not the power supply) is present, acts to at least warn the operator and/or discourage his entry into a possibly hazardous situation, for example the device may operate an audible or visual warning device 10 and/or it may act to maintain operative a lock on the equipment housing access panel or door. <IMAGE>

Abstract: Single crystal compound semiconductor substrate material of constant composition is grown from the melt 2 by a method in which compositional control is effected by adding to the melt source material comprising two or more different materials 5, 6 at a rate matched with the rate of extraction of material 4 from the melt by the crystal growth. <IMAGE>
Patent GB-2131493-A (GB)
Title: Fuel injection pumping apparatus
Inventor: CLEGG JOHN WILLIAM
IPC: F02M41/14
Filed: 1983-10-11
Abstract: A fuel injection pumping apparatus includes a throttle member 18 angularly adjustable by a governor mechanism 24 to control the fuel flow from a low pressure pump 13 to a high pressure pump 10. The throttle member is also axially movable by fuel under pressure in a direction to slightly increase the amount of fuel supplied when the engine speed is above a predetermined value and is movable in the opposite direction when the engine speed is below said value, the rate of movement of the valve member in said opposite direction being restricted by a dashpot. The arrangement has the effect of minimising the possibility of engine stall when decelerating the engine with the throttle closed. At the predetermined speed, pressure from the pump 13 is sufficient to lift a valve 22 off its rest and pressurise a chamber within cup member 26. The end of the throttle member 18 within the cup 26 is of increased area whereby the throttle member is caused to be moved downwardly. When pressure falls, the valve 22 closes and the pressure in the cup 26 bleeds away at a rate which restricts the throttle's return speed. <IMAGE>
Patent GB-2129101-A (GB)
Title: Ball valve
Inventor: WILLIAMS PETER CHARLES
IPC: F16K5/06
Filed: 1983-10-13
Abstract: A soft-seated fire-safe ball valve includes a pair of seat assemblies each comprising a rigid reinforcing ring (100), an elastic seat ring (102), and a deformable, heat-resistant secondary seat ring (104) interposed between the elastic seat ring and a shoulder (70). Upon fire damage to the elastic seat ring (102), the secondary seat ring (104) engages the ball member (c) to seal the valve (Fig. 6). Also, a weir ring (130) may be received in the seat ring (102). The weir ring (130) inhibits extrusion of a substantial portion of the seat ring (102) such that the seat assembly operates to maintain a fluid-tight seal upon partial destruction of the elastic seat ring. <IMAGE>

Title: A process for the production of an inactivated adjuvated vaccine against Aujeszky disease
Inventor: KELEMEN MARIA
IPC: A61K39/245
Filed: 1983-10-24
Abstract: A vaccine against Aujeszky disease is produced by inoculating a cell culture, preferably of primary chicken embryo cells or primary calf testicle monolayer cells, with a virulent strain of the virus deposited in the Hungarian Institute of Public Health under the number 00236/82. The virus used to inoculate the cell culture is preferably obtained from a suspension of the brain of a rabbit that contracted the said strain of Aujeszky disease. The virus propagated in the cell culture is then inactivated, preferably with ethylene imine, optionally obtained by cyclising bromoethyl amine immediately prior to use, and then mixed with an adjuvant, which is advantageously an oily adjuvant e.g. Phylaxia incompletely oily immunoadjuvant. The vaccine is effective to protect livestock and domestic animals from Aujeszky disease.

Title: Command optics
Inventor: AMON MAX
IPC: F41G7/26
Filed: 1985-01-17
Abstract: An optical system provides guidance in the form of a modulated beam for a beamrider missile. The system comprises first and second zoom type optical subsystems providing guidance to the missile when an exhaust plume from a rocket engine is difficult to penetrate. The first optical subsystem PATH D is utilized in a closed loop servo system for positioning a mirror 9 gimballed about two axes, such that it continuously tracks the missile. The second optical subsystem PATH C, along which the beam is directed, comprises negative 12 and positive 13 optical groups forming a defocusable beam expander. These groups 12, 13 are initially defocused. During flight, the negative group 12 is moved away from the positive group 13, toward the focussed position, maintaining, via mirror 9, a constant beam diameter. The positive and negative groups 12, 13 are free of spherical aberration and coma, such that the shape of the beam is not disturbed in any zoom position.

Title: Differential housing
Inventor: WILSON DENNY R
IPC: F16H48/08
Filed: 1985-04-15
Abstract: An improved combined differential bearing cap support and housing cover structure for a differential axle assembly is disclosed. The differential axle assembly includes a housing having a cover, a pair of drive axles rotatably mounted within the housing by respective bearing means, and means connected to the drive axles for applying motive power thereto while still permitting relative rotation thereof. A bearing cap support member is attached to the housing so as to engage a respective one of the bearing means and maintain it in position about a respective drive axle. The bearing cap support member includes a central portion which extends outwardly and terminates in a flat outer surface. A pair of boss members are formed integral with the housing cover. Each of the boss members terminates in a flat outer surface adapted to abut a respective one of the flat outer surfaces of the bearing cap support members when the cover is secured to the housing. The abutment of the bearing cap support members and the boss members provides a stable support for the internal elements of the differential axle assembly, thereby minimizing the defections or other relative movements therein when motive power is applied. <IMAGE>
