Title: Improvements in cop winding machines
IPC: B65H54/14
Filed: 1939-06-13
Abstract: 529,958. Winding yarns. REINERS, W. June 13, 1939, No. 17302. Convention date, July 28, 1938. I[Class 120 (ii)] In a cop winding machine the speed of the winding spindle is reduced at the completion of the cop and while the thread guide or winding spindle is being returned to its initial position so that only a few coarsely spaced turns are laid on the completed cop prior to doffing. As shown the thread F is traversed in one direction by the helically-grooved drum 8 and in the reverse direction by reason of the oblique pull exerted by the fixed thread guide 9 and the winding spindle is fed forward during the winding and rotated by gears 5, 6 driven from the friction gear 3 engaging the driving wheel 2 on the shaft 1. When doffing is to take place, a cam 17 on the shaft 16 causes the return of the spindle to its initial winding position. A cam 18 moves the gear 3 out of engagement with the wheel 2 and a cam 28 actuates a lever 26 to allow a spring 27 to engage a gear 24 driven from the shaft 16 with a gear 25 on the shaft 7 and drive it at the reduced speed. In a modification in which the winding spindle is traversed and the thread guide fed along the spindle, the spindle carries a double cone clutch which during the winding is held in engagement with a wheel driven from the main shaft and, on completion of the winding, is shifted to disengage the clutch from this wheel and engage it with a wheel driven at a reduced speed from the main shaft. In a further form in which the thread guide is both traversed and fed along the winding spindle, the spindle is frictionally driven from the main driving shaft and at the completion of the cop the driven friction wheel is disengaged from the main drive and engaged with a friction wheel driven from an independent shaft to give the reduced spindle speed.

Title: Improvements in or relating to magnetohydrodynamic electrical generator systems
Inventor: HORN GEORGE
IPC: H02K44/08
Filed: 1964-04-28
Abstract: 1,048,304. Turbine plant. CENTRAL ELECTRICITY GENERATING BOARD. March 31, 1965 [April 28, 1964], No. 17609/64. Heading F1Q. [Also in Divisions F4 and H2] In an open cycle MHD generator system the combustion air is compressed in a compressor 30 and passed through a first preheater stage 17 which uses the waste heat from the generator working fluid and through a second independently fired pre-heater stage 21 before flowing to the combustion chamber 11. The waste heat of the working fluid is also used to raise steam for a conventional turbogenerator system. The second pre-heater 21 may comprise a recuperative heat exchanger using ceramic tubes or a regenerative type with a stationary or moving matrix and the heating element is fired with fuel and pressurized air taken from the first heat exchanger thus eliminating pressure differentials between the two flow channels. Gas temperature in preheater 21 may be controlled by recirculation and the used gases are passed through a low pressure gas turbine 25 into a steam raising and superheater stage in the generator exhaust duct. The steam plant has water pumped by pump 28 through a heat exchanger 31 and tubes 32, where it is used to cool the MHD generator, into steam raising section 16 and after superheating at 33 is passed through turbine 26 into condenser 27. The first pre-heater stage may be formed in two parts joined externally through a high pressure gas turbine if the pressure output of the compressor is high enough. Valves are provided to by-pass both gas turbines if desired. Power generated at electrodes 14 of the generator is inverted in invertor 15.

Title: Improvements in or relating to the control of electric motors
Inventor: JOHNSON HAROLD FREDERICK
IPC: H02P3/06
Filed: 1958-06-03
Abstract: 862,096. Control of motors; actuation of switches. MACHINE SHOP EQUIPMENT Ltd. Feb. 13, 1959 [June 3, 1958], No. 17727/58. Classes 38 (3) and 38 (5). When an electric motor is operating in a forward direction, a cam 16 maintains a resilient arm 14 out of contact with a plunger 13 so that contacts 11, 12 remain closed. The motor is stopped by reversing its supply, a relay 18 being energized by actuation of a push-button to maintain the reverse-circuit intact until the motor is braked to a standstill. This causes arm 14 to engage in slot 17, and if the motor tends to rotate in the reverse direction, the arm 14 depresses the plunger 13 to open the contacts 11, 12. The relay 18 is then de-energized to break the circuit of the motor. When the motor is restarted in the forward direction, the contacts 11, 12 are automatically reclosed. In another arrangement, the arm 14 co-operates with the underside of an annular flange during forward operation, and, when the motor approaches a standstill, the arm rides up an inclined slot in the flange and on to the upper surface. This causes actuation of the trip switch and consequent disconnection of the motor, Figs. 3, 4 (not shown).

Title: Improvements in and relating to moulds for use in the vulcanization of rubber or like soles in shoes
Inventor: FRASER ROBERT MARTIN
IPC: B29C35/00
Filed: 1951-08-02
Abstract: 692,676. Vulcanizing rubber &c. soles to shoe uppers. S.A.I.C. FABRICA ARGENTINA DE ALPARGATAS. Aug. 2, 1951, No. 18331/51. Class 87 (ii).  A one-piece mould for use in vulcanizing a rubber shoe sole to an upper has a recess for the sole and, mounted around the recess, a flexible sheet made up of at least two parts, this composite sheet extending inwards over the edges of the recess and having, above the recess, an opening contoured to receive with a sealing fit the lower part of the shoe upper. The sole 2 rests in the mould 1 and the upper 5 to which the sole is to be vulcanized is carried by a last 6. A sheet 3 of flexible material, e.g. sheet metal, covers the surface of the mould and is held down at its edges by fastenings 4, the edge of the opening in the sheet, of the same shape as the outline of the upper where it is to be joined to the sole, projecting slightly inwards over the mould opening. When the upper is pressed down on the sole the sheet 3 bends at this projecting edge and forms a seal at the joint between the mould and the upper, the sealing effect being increased by the pressure of the edges on the top of the mould. The top of the mould may be flat, with the under surface of the sheet in contact with the whole of it, or the centre part may be raised as shown, in which case tightening the. fastenings 4, e.g. by wing nuts, will tend to make the centre part of the flexible sheet press upwards against the upper 5 and so increase the pressure at the joint. The seal may be improved by bevelling the sides of the mould to form a sharp edge. To facilitate the removal of the upper with sole attached the sheet 3 may be subdivided, e.g. into four parts, as in Fig. 2. Instead of the fastenings 4 acting directly on the sheet 3, the sheet may be bordered by thicker material which may have hinge elements mounted on it.

Abstract: 968,458. Road traffic signals. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. April 8, 1963 [May 12,1962], No.18352/62. Heading G4Q. In a traffic signalling system controlling an intersection two spaced-apart sets of signals are provided on each approach road, the operation as regards to at least one traffic stream being such that for part of the time period which a conflicting stream flows, the stream in question is halted, but for the remainder of the time it is given right of way at the set of signals further from the junction. Assume initially traffic is flowing along the N-S route with signals NS1, NS2, SN1, SN2 all "go" (phase 1) and signals WE1,WE2, EW1, EW2 all "stop". After a predetermined time, the outer signals NS2, SN2 change to "stop" and the outer signals WE2, EW2 change to "go" (phase 2). After a further period, arranged to allow traffic passing WE2, EW2 signals to arrive at WE1, EW1 with their normal running speed, WE1, EW1 change to go and NS1, NS2, change to "stop" giving free flow along the EW route (phase 3). Under light traffic conditions the signals may be arranged to change directly from phase 1 to phase 3. The signals may be vehicle operated or operated on a fixed time cycle.
