Title: Improvements in or relating to automatic electric circuit breakers
IPC: H01H71/40
Filed: 1941-05-23
Abstract: 549,554. Electrically-released switches. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. May 23, 1941, No. 6629. Convention date, June 8, 1940. [Class 38 (v)] In an automatic circuit-breaker adapted to trip electromagnetically without time-delay on severe overloads and having inverse-time characteristics for moderate overloads, the electromagnetic armature is restrained by a loadcurrent carrying bimetal strip adapted to deflect in the tripping direction so as to give decreasing restraint with rising current. On severe overloads, the armature is attracted and, aided by a spring, overpowers the bimetal. The latch lever 63 is pivoted at 75 to the upper limb of a U-shaped magnet core 69 and has a projection 79 on an extension 77 which co-operates with the free end of a bimetal strip 67 in series with the magnet winding 73. A spring 83 anchored to the lever 63 provides a constant force in the tripping direction, which force is adjustable by a screw 87 having its threads engaging the coils of the spring. The latching surfaces 79, 81 are so arranged and directed that the force of opening springs 33 does not bias lever 63 in either direction, but in Fig. 5 (not shown) they are arranged to provide an extra bias in the trip direction. The surface 81 is formed on a lever 35 which is pivoted to a frame 27 at 45 and retains the movable contact lever 15 by means of the overset toggle 37, 39.. The pivot 45 also serves as one anchorage for the spring 33 and to support the operating handle lever 41 having a connection 59 with a lever 43 pivoted to the toggle-knee. Provided 35 is latched, manual operation can be effected by breaking and resetting the toggle. If 35 is unlatched the whole mechanism rotates in a generally-anticlockwise direction without movement of the handle and collapse of the toggle, resetting being effected by moving the handle to open position to break the toggle and then back to cloced position to overset it. Resetting can be effected with very little delay after disconnecting a heavy overload owing to the strip 67, freed from the force of the electromagnet, springing back slightly.

Title: Catalytic process for the production of pyridine and/or piperidine
Inventor: CORRAN JOHN ANTHONY
IPC: B01J23/28
Filed: 1962-02-21
Abstract: Pyridine or piperidine or mixtures thereof are prepared by passing a mixture of tetrahydrofurfuryl alcohol and ammonia in the vapour phase at elevated temperature over a catalyst containing zinc oxide, molybdenum oxide and alumina.  The zinc oxide and molybdenum oxide in said catalyst may be present as zinc molybdate and static or fluidised catalyst bed techniques may be employed.  A reaction temperature of 300 DEG  to 400 DEG C. favours the formation of piperidine whilst a temperature of 450 DEG  to 600 DEG C. favours the formation of pyridine.  Inert carrier gas, e.g. nitrogen or steam, may be mixed with the vapour stream containing the reactants and it is preferable to add hydrogen to said stream when piperidine is the desired product.  The gaseous reaction product is condensed and may be washed up in conventional manner after, if desired, dehydrogenating the piperidine to pyridine or reducing the pyridine to piperidine. The second Provisional Specification also refers to the use of a cobalt oxide/molybdenum oxide/alumina catalyst.  U.S.A. Specification 2,963,484 is referred to.
Patent GB-1293221-A (GB)
Title: Improvements relating to fuel injection pumps
IPC: F02M41/12
Filed: 1970-02-12
Abstract: 1293221 Fuel injection pumps ROBERT BOSCH GmbH 12 Feb 1970 [12 Feb 1969] 6762/70 Heading F1A In a fuel injection pump the fuel pressure of the feed pump 42 governs the timing and the supply of excess fuel for starting and is itself governed by spillage from suction chamber 3 to the feed pump inlet via overflow 41 controlled by spool 47. Fuel is supplied to the delivery passages 5 via a groove 7 on the distributing piston 2, and injection is terminated by spillage through conduits 8a, 8b when shuttle 10 is moved against spring 13 by fuel from a cylinder 16. During starting fuel from cylinder 16 is passed directly via conduits 23a, 23b to chamber 3 thus preventing movement of the shuttle 10 and allowing excess fuel to be supplied to the engine. As the pressure in chamber 3 rises with increasing engine speed a spool 24 is moved to close 23a. The fuel within chamber 3 also acts on a hydraulic device 32 coupled to the cam 31 so that the cam may be rotated to vary the timing. Above the pressure necessary to close conduit 23a chamber 3 is regulated by overflow 41 and spool 47. The spool is spring-loaded within a bush 50, and in the rest position abuts a spring- loaded stop 54, and a throttle bore 60 is defined in the spool. Low-pressure fuel in conduit 41 passes through bore 60 with little throttling and passes to the feedpump inlet via bore 57 in the bush. At increased pressures the throttling action is increased and spool 47 is displaced against spring 49 to uncover a bore 48 in bush 50 which communicates with overflow 41. In another embodiment, Fig.4 (not shown), a spool without a throttle bore is prevented from fully closing the bore 48 by an adjustable stop. The arrangement of the spool and bores in the overflow allow a rapid pressure increase in the suction chamber thus causing the excess fuel to be shut off as rapidly as possible.
