Title: Improvements in or relating to electric switches
IPC: H01H13/58
Filed: 1932-10-04
Abstract: 413,255. Snap - action switches. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. Oct. 4, 1932, No. 27567. Void [Abridged as open to inspection under Sect. 91 of the Acts, Oct. 8, 1932]. [Class 38 (v).] The switching member of a snap-action switch is movable under the influence of a spring in which energy is stored by movement of an actuating member, the switching member being prevented from movement by means associated with the actuating member during the period of energy accumulation. In a lampholder switch, Figs. 1 and 2, a pin 11 on the actuating member 4 is mounted between the ends 5A, 5B of a spring 6. On movement of the member 4, the pin engages one end of the spring, while the other end is held by a lug 8 on the switching member 3, the switching member being prevented from rotation by the engagement of another lug 7 with the end of the actuating member 4. On completion of the movement of the actuating member, the lug 7 traverses the path P, Q or P', Q<1> and the switch rapidly closes or opens under the influence of the spring. In a push-button switch, Fig. 7, the push-button 21 carries a cam surface 32 which engages a pin 33 on an intermediate member 34 carrying another pin 35 engaging the ends of a spring 31. The push-button is prevented from rotating by the engagement of a fixed pin 26 with a slot 27. On depressing the push-button against the action of a spring 36, the cam 32 rotates the member 34 and strains the spring 31, the other end of the spring being held by a projection 28 on the switching member. At the end of the movement, a lug 29 on the switching member escapes from a slot in the push button, and the switching member moves rapidly under the action of the spring 31. In another construction, Fig. 8, the push-button 38 and switching member 39 are locked, during depression of the button, by the engagement of a square-section pin 41 with a corresponding bore in the button, while cam surfaces 43 on the button engage lugs 42 on an intermediate member 40 and rotate the latter to strain the spring 44. On releasing the button, it returns to its normal position under the influence of a spring 45, and the switching member rotates rapidly under the influence of the energy stored in the spring 44.

Title: Method of providing an insulated winding in slotted magnetizable cores of dynamo electric machines
IPC: H02K15/12
Filed: 1971-06-14
Abstract: 1349386 Making coils for dynamo-electric machines WESTINGHOUSE ELECTRIC CORP 14 June 1971 [5 Aug 1970] 27680/71 Heading B3A [Also in Division H2] Conductors 36, 38 in a dynamo-electric machine core slot 30 are insulated by standing the core on end (i.e. with the slot vertical), introducing powdered resinous material 48 into the slot whilst simultaneously vibrating the core/conductor assembly, so that the powder compacts into the interstices between the conductors and between the conductors and the slot wall, and then heating the assembly to fuse and cure the resin. Before the assembly cools completely, powdered resin is applied to the end turns, and the assembly is then reheated. The resin may be thermoplastic, or may be formed by a thermosettable blend of epoxy resins, a pigment, an amine curing agent and a silica filler. The slot liners 40, 42 are formed of mica flakes bonded together by a fusible resin, so that when the assembly is heated the liners fuse with the packing material 48.

Title: Improvements in or relating to gas turbines
IPC: F02C7/00
Filed: 1959-08-13
Abstract: 867,637. Turbines. BROWN, BOVERI & CIE A.G. Aug. 13, 1959 [Aug. 13, 1958], No. 27698/59. Class 110 (3). A gas turbine plant for ship propulsion comprising ahead and astern turbines connected in parallel to at least one fluid supply and primary valve means for controlling the fluid supply to the turbines has, in the fluid supply to at least one of the turbines, secondary valve means to provide an overriding control on the effective fluid supply to that turbine when the primary valve means is set for supplying fluid simultaneously to both turbines. A forward turbine 1, Fig. 1, and a reverse turbine 2 are connected to a common shaft 3 driving, a ship's propeller. The driving medium is supplied through a pipe 4 and the flow to the ahead turbine is controlled by the valve 5 and to the reverse turbine by the valve 6. A by-pass pipe 8 arranged between the inlet and outlet of the turbine 1 contains a valve 9. For normal ahead running valve 5 is open and valve 6 closed. For reverse running valve 6 is open and valve 5 closed. Under these conditions, the turbines are regulated by controlling the gas condition at the turbine inlet. For manoeuvring in harbour both valves 5 and 6 are open and the transition from forward to reverse running and vice versa is achieved by regulating the valve 9. To obtain full torque, it is only necessary to close valve 5 or 6. The by-pass may be arranged around the turbine 2 or by-passes may be arranged around the turbines 1, 2. In a modification, Fig. 2 (not shown), the valve 5 is replaced by a two-position flap-valve (opened, closed). In another modification, Fig. 3 (not shown), the valves 5, 6 are replaced by a single valve. Arrangements in which the turbines have two supply pipes are also described.
