Title: Improvements in or relating to automatic friction drop hammers
IPC: B21J7/44
Filed: 1960-03-29
Abstract: 885,262. Drop hammers. MASSEY Ltd., B. & S., WELLS, L. W., and MIDDLETON, B. March 29, 1960, No. 10997/60. Class 83 (4). An automatic friction drop hammer whose holdup gear comprisesa band brake and whose lifter mechanism includes a band-type friction clutch released by a spring and actuated by a pull cord 14, Fig. 8, wrapping around a revolving shaft, both being controlled pneumatically by a foot threadle 16, Fig. 1, to give one or a succession of light or heavy blows dependent upon the lift of the tup, has its pull cord passing through a tubular guide 39 on an air cylinder 36 and actuated by a piston-rod 38 projecting out of the air cylinder by means of a finger 41 engaging an adjustable stop 40 on the cord, and adjustable stop means 75, 83 are provided to positively arrest the downward movement of the pistonrod thereby to release the pull on the cord and hence determine the lift of the tup. The hammeris similar to that described in Specification 842,169, wherein the foot threadle 16 upon being moved to the short stroke position S, operates a pilot valve 18 controlling a relay valve 31 which energizes air cylinder 28 to release the hold-up brake. The tup thus falls and near the end of its downstroke a trip block 60 driven by a chain 61 to reproduce the movement of the tup, actuates a pick-up valve 63 which acts through a distributing valve 92, short stroke flow-control valve 95 and relay valve 87 to allow air above piston 37 in cylinder 36. The flow control valve 95 restricts air flow on short stroke working to ensure the down stroke of the tup is completed. Thus pistonrod 38 moves downwardly to actuate the pull cord 14, Fig. 8, and is arrested upon engaging the short stroke stop 76. Air is released instantly from above the piston 37 which rises due to constant air pressure below it, thereby releasing the tup ; the upstroke of the piston 37 is cushioned by piston 99 in chamber 98, as described in Specification 885,219. When long strokes are required, the threadle 16 is depressed to position L, whereby the short stroke stop 76 is withdrawn by air motor 45 and linkage 78, 79, Fig. 8. The downstroke of piston-rod 38 is then arrested by long stroke stop 83 and a long stroke flowcontrol valve 96 delays the release of air above piston 37 and thus delays release of the pull cord. Both of the stops 75, 83 are adjustable independently along guide rods 69 after releasing clamping handles 74, 85. A rotary valve 97, Fig. 1, selects automatic or manual operation of the hammer. Specifications 813,045 and 842,877 also are referred to.

Filed: 1968-03-07
Abstract: 1,148,428. Demodulators; noise suppressors. GENERAL MOTORS CORP. 7 March, 1968 [13 March, 1967], No. 11111/68. Headings H3Q and H3W. A receiver for modulated waves has separate demodulator stages for the two half-cycles of the incoming wave, each such stage including clipping and biasing devices to limit the amplitude of the half cycle, a common conductive path combining the outputs of the stages in opposite phases to pass a resultant signal to the A.F. stage. By including an attenuator in one demodulator, the A.F. envelopes will be of different amplitudes so that their resultant will be of similar waveform but of reduced amplitude. Any noise peaks will however be clipped to the same level so that their combined output will be zero. In Fig. 1, the half-cycles are rectified by diodes D1 and D2 respectively and the carrier filtered out by RC circuits 10, 12, 14 and 18, 20, 22. One half-cycle is passed to point E via clipping diode D3 while the other is first attenuated by voltage divider 26, 28 and then clipped by diode D4. The clipping level is set by the voltage at 32 applied through resistor 34 to diode D4 and through resistors 27, 29 to diode D3, and also depends on the forward bias developed by the signal across resistor 26. The combined A.F. signal at E is taken off through an emitter-follower T1.

Title: Improvements relating to polyphase windings for dynamo-electric machines
IPC: H02K3/28
Filed: 1948-04-26
Abstract: 656,655. Winding layouts for dynamo-electric machines. KREBS, E. W. April 26, 1948, No. 11397. [Class 35] In a distributed winding for a dynamoelectric machine having three or more phases, each phase extends over 360/m electrical degrees, " m " being the number of phases, and the number of conductors in each slot is in the ratio of the sines of the respective electrical angles between the centres of the coil sides and the nearest edge of the phase zone. The edge of the zone is taken as 90 - 180/m electrical degrees from the midpoint between two adjacent zones of the same phase. In one form, Fig. 1, in which the centre of a zone, e.g. D, having six slots, falls between two slots, the number of turns A<SP>1</SP> in the various slots are in the ratio sin 10 degrees, sin 30 degrees, sin 50 degrees, symmetrically on either side of the centre-line. Alternatively, the centre of the zone coincides with the centre of a slot as in Fig. 2, in which case the numbers of conductors in successive slots are also symmetrical about the centre-line. If the centre of the zone does not lie in a symmetrical position with respect to the slots, the conductor numbers required for the slots are not symmetrical. A layout is also described in which the span of the zone is not an integral number of slot pitches so that intervals between adjacent zones of the same phase cannot be 180 degrees and the two edges of the zone are not the same distance from the centre of the middle slot of the zone. The end connections to the windings may be successive so that all the coils have the same span, or zones of the same phase may be interconnected by concentric end-connections. In a preferred form, however, the coil sides of each phase zone are split into symmetrical halfzones and joined to the next half-zone by concentric end connectors. Other arrangements are also described and the slots may be skewed.
