Title: An Electric Motor and Associated Equipment for Rotating a Body
IPC: H02K17/06
Filed: 1967-12-04
Abstract: 1,151,467. Electric motor driving arrangements. SIEMENS A.G. 4 Dec., 1967 [2 Dec., 1966], No. 55137/67. Heading H2A. An induction motor operating on either two poles or an alternative higher pole-number (four or six poles) for automatic washing machines, has separate windings for the two pole numbers, the higher having an auxiliary capacitor winding for starting at the lower speed and the lower having a main winding only, centrifugal means acting to interpose reduction gearing when the motor is operating at its higher pole number, and an automatic clutch coupling it direct when the motor is running fast. By this means a low tub speed is obtained for washing and a high speed for drying. The clutch permits some slip to avoid stalling the motor when the gearing is suddenly replaced by a direct drive. To initiate the disengagement of the reduction gearing, the high-speed winding is momentarily energized while the motor is still running on the higher pole-number. This forces the speed up above the no-load lower speed, and the clutch automatically operates to disengage the gearing and couple the drum directly to the motor. The low speed winding is preferably symmetrical so that it may be reversed by changing over the capacitor. The high-speed winding is sinusoidally graded and has a band-width of 2/ 3  pole-pitch. The lamination shown has 24 slots of which two groups N are larger, the lamination being elongated to accommodate them. The low-speed winding lies in all the slots equally, but the high-speed winding is confined to the 16 large slots N. Stack-welding recesses S are provided.

Title: Phase synchronizing system
IPC: H03L7/10
Filed: 1969-11-18
Abstract: 1,249,953. Automatic phase control. BURROUGHS CORP. 18 Nov., 1969 [29 Nov., 1968], No. 56300/69. Heading H3A. In an A.P.C. system comparisons are made between the standard and controlled signals at two succeeding intervals of time, and means are provided for deriving a control signal which is simultaneously responsive to both comparisons. The two signals are applied at inputs 4, 7 to produce, at the output of AND gate 20, a train of pulses whose widths are dependent on the instantaneous phase difference between the two inputs. The output signal triggers a train of monostables 22, 23, 24 to produce signals which, together with the signal from gate 20 control gates 26, 28, 30, 43. During the time a pulse is present at the output of gate 20, gate 26 opens and capacitor 27 charges from constant current source 25 to a potential dependent .on ,the duration of the pulse, i.e. to the phase difference. Gate 30 is subsequently opened and this charge is transferred to capacitor 31. Capacitor 27 is then discharged by gate 28 and recharged to a potential dependent on the phase difference existing in the next cycle, so that the charges on the two capacitors always represent the phase difference during succeeding cycles, t i  and t i+1 . These two signals and a reference signal td are fed to a summing circuit 41 which produces an output it being shown that a control signal of this form can produce phase lock within two cycles, at a phase difference t d .  If the two input signals differ in frequency, they may be reduced to the same frequency by dividers (3, 6 Fig. 1, not shown).

Title: Electrical discharge machining
IPC: B23H1/02
Filed: 1973-12-11
Abstract: 1453305 Electro-erosion COLT INDUSTRIES OPERATING CORP (ELOX DIVISION) 11 Dec 1973 [14 Dec 1972] 57409/73 Heading B3V In electrical discharge machining, electrical breakdown of the machining gap is used to produce a pulse initiating a digitally controlled period of discharge, or "on time". In the embodiments described, the "off time" period is also digitally controlled. During the off time, an off time clock 80 feeds pulses to a manually preset counter 78 which counts down to zero and produces a signal at D, which through terminal Y, inverter 26, and terminal Z, resets a flip-flop 92. One output of this on line 94 provides a pulse fed to a drive stage 54, Fig. 3, of a transistor 38 in series with the power source 36 and machining gap. The other output of flip-flop 92 provides a signal at terminal C to turn clock 80 off, and a signal at terminal T energizing a one-shot multivibrator 62 which delivers a pulse through transformer 77 to terminal 42, whence a pulse is fed to drive stage 54, Fig. 3, to turn on transistor 38 in series with the power source 36 and machining gap, to apply voltage to the gap. When electrical breakdown of the gap occurs, voltage drop across resistor 58 in series with the gap produces a pulse at the output terminal 30 of transformer 56, and this is fed, Fig. 1, through inverter 26 and terminal W to operate flip-flop 90, the output from which through terminals X and A turns an on time clock 12 feeding pulses to a manually preset counter 10 which counts down to zero and produces a pulse at B, which through inverter 26 and terminal R sets both flip-flops 90 and 92. The output of flip-flop 90 through terminal A turns clock 12 off. One output of flip-flop 92 through terminal S operates a one-shot multivibrator 60 which delivers a pulse through transformer 71 to terminal 40, whence a pulse is fed to drive stage 54, Fig. 3, to turn transistor 38 off and terminate discharge. The other output from flip-flop 92 through terminal C turns on the off time clock 80 so that converter 78 begins to count down again, completing the cycle. Each counter displays the count manually set in it. In another embodiment, Figs. 4 and 5 (not shown) a single clock is arranged to feed either counter, as required.

A thermally insulated pipe section comprising coaxial inner and outer tubes, adapted to be connected to similar sections to form a pipe system for installation underground, has a coupling sleeve mounted on one end of the inner tube and sealed with respect thereto, the sleeve extending at least partially within the outer tube and being embedded in thermal insulation material filling the space between the outer and inner tubes, the other end of the inner tube protruding beyond the end of the outer tube and being receivable slidably and sealingly within the coupling sleeve of an adjacent section, such that substantially continuous thermal insulation is provided along the length of the inner tube system while a gap is left between adjacent inner tubes to allow for thermal expansion. In one embodiment, Fig. 2, the inner tubes 4 are of copper coated with silicone grease to allow axial expansion within the insulation material 48 which is a foamed polyurethane, the coupling sleeve 26 is a bronze casting, provided with ribs 28, 29 and associated grooves 30 containing sealing rings 32, and the outer tubes 6 are of asbestos cement. The coupling sleeve is assembled on to one end of one inner tube, with an integral flange 34 in abutment with the end of the inner tube, and resilient members 10, 38, which are mounted respectively on the coupling sleeve and the mating end of the adjacent inner tube, are fitted into one outer tube 6, prior to injection of the polyurethane foam, the latter being caused to fill the space between inner and outer tubes and also to fill holes 24 in the member 10. Adjacent sections are then fitted together, the free end of the adjacent inner tube entering the coupling sleeve 26 and being sealed by the ring 32, while the member 10, which is provided with flexible lips 18, enters the adjacent outer tube to couple the outer tubes together. Abutment of the outer tube end 36 with a flange 12 of member 10 limits insertion of the tube 4 to allow room for thermal expansion. In a modification, Fig. 4, neither of the resilient members 60, 80, which replace the members 10, 38 acts as a coupling member, a separate P.V.C. plastics sleeve 86 being used to connect adjacent outer tubes 56 which are also of P.V.C. plastics material, a rubber sealing gasket 90 fitted in a recess 88 of sleeve 86 engaging the outer tube to seal the latter.

Abstract: 590,387. Moulding tiles. PEGSON, Ltd., and DAVIDSON, D. J. Feb. 9, 1945, No. 3323. [Class 87 (ii)] [Also in Groups XXIV and XXX] A machine for making tiles, in which pallets P travel along tracks 2 in end-to-end contact, is characterized by driving mechanism for the pallets comprising a rotary wheel 4 on which are pivoted pawls 5 which engage the pallets one after another. The pallets are fed to an endless belt which delivers them to the tracks 2, on which they slide, pushed on by those behind, until picked up by the pawls 5. The endless belt moves faster than the pawls, to ensure that the pallets pass through the machine in contact with each other. The ends of the pawls have rollers 26 which engage fixed cams 28 to urge the pawls outwards, against the tension of springs 21, into engagement with the pallets. The pawls may normally project from the wheel 4 sufficiently to allow the cams 28 to be dispensed with or to be used only to control the inward movement of the pawls. A bar 31, attached at its rear end to a pivoted transverse bar 32 and at its forward end to a spring- loaded tranverse bar 33 presses on the pallets to hold them in contact with the pawls and to act as a brake. For wide pallets the bar 31 and the wheel 4 may be duplicated or a single wheel may carry two sets of pawls. From under the bar 31 the pallets pass in turn under the mortar compressing unit, a vertically reciprocating severing knife, a reciprocating colour or topping box and a punch, all these devices being driven from the shaft 15 of the wheel 4. In a modification the pawls push the pallets one by one from the bottom of a hopper. The tracks 2 may be adapted to hold the pallets down against the thrust of the pawls. According to the Provisional Specification the pawls may pull, instead of push, the pallets.
