Title: Improvements in or relating to shoe upper lacing machines
IPC: A43D11/08
Filed: 1952-05-13
Abstract: 716,395. Shoe-lacing machines BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation) May 12, 1953 [May 13, 1952], No. 12052/52. Class 43 A shoe-upper lacing machine of the type described in Specification 474,025 having a cord tensioning device is provided with adjustable means for stabilizing the timing of alternate tensioning and relaxing of the lacing cords by said device irrespective of the thickness or number of said cords, comprising an eccentric rotatable by an adjusting member and means for determining various positions to which said adjusting member may be moved on changes being made in the number or thickness of cords. This stabilization is effected by maintaining constant a lost motion for all total thicknesses of cord in use. The tension device comprises pairs of washers 24 between which the cords are disposed after passing through supply tubes 36 on their way to the lacing mechanism via the notched thread-engaging plate 18 'secured to takeup actuating arms 20 rocked by rockshaft 22. Tension on the cords is applied by clamping pressure exerted between the washers of each pair by a spring 30, Fig. 4, adjustable by nut 34, the pressure being released by the forked arm of a bell crank lever 38 acting on a slider 32 against spring 30, the lever 38 being rotated on vertical pin 40 by a lever 42 having spaced hub portions rotatably ad justable on the rock-shaft 22 to vary the lost motion gap between the levers 42 and 38 to compensate for lack of uni fbrmity in timing of the application or release of clamping pressure on the washers 24 due to variations in the lost motion provided between lever 38 and slider 32, brought about by variations in total cord thickness. This lost motion also ensures uniformity of clamping pressure for all total cord thicknesses. The hub of lever 42 has secured to it a perforated plate 48. An eccentric portion of the hub of adjustable arm 52 rotates on a shoulder screw 50 secured to the hub of lever 42 and within a block 54 connected by rod 56 to a rocking cam and lever mechanism, the arrangement being such that rotation of arm 52 in block 54 causes lever 42 to be shifted with respect to curved surface 44, Fig. 6, of the lever 38 to vary the lost motion gap therebetween. The plate 48 is calibrated as to sizes of total thickness by a series of holes 70 with suitable indices 72 and the arm 52 is retained in adjusted position by a slidable spring-pressed plunger 74.

Abstract: 1527741 Automatic control of speed RCA CORPORATION 30 Jan 1976 [25 March 1975]  12395/75 Headings G3N and G3R A speed control arrangement for a brushless D.C. motor 12 includes a resolver 14 driven by the motor and having its primary windings energized by phase quadrature signals derived from a reference oscillator 28 through phase splitting network 20. The phase of the output signal from resolver 14 is compared with the phase of a desired signal derived from reference oscillator 28 by phase shifting circuit 26 to provide an error signal on line 27 which is filtered to provide a near constant voltage representative of the phase difference. A shaping network 68 alters the signal to optimize the response of the loop and this signal is amplitude modulated by the output frequency of the resolver. The demodulators 54, 56 operate at the frequency and phase of the supplies to the resolver primary windings to produce the quadrature signals for driving motor 12. The phase shifting circuit consists of a plurality of JK bi-stable circuits, shown in detail in Fig. 2, (not shown) forming a speed control circuit 30 and a pulse logic circuit 32 which enables normal or slowing speeds to be selected in either direction of rotation. Effectively pulses are added or subtracted from the output of oscillator 28 to determine the direction of change and the rate at which the subtraction or addition occurs determines the motor speed and this is done by selecting particular dividers for inclusion in the circuit.

IPC: H03C1/34
Filed: 1961-04-07
Abstract: 964,589. Semi-conductor devices. WESTERN ELECTRIC CO. Inc. April 7, 1961 [April 7, 1960; April 13, 1960; April 20, 1960], No. 12516/61. Heading H1K. [Also in Division H3] An electro-mechanical circuit element comprises an acoustic or ultrasonic delay element composed of a piezo-electric material having a conductivity which can be chosen or varied to produce a desired transmission effect. Cadmium sulphite and zinc oxide are examples of suitable materials which are both piezo-electric and semi-conductive. The invention is based upon the fact that some of the energy of the mechanical wave is used in the creation of electrostatic fields due to the piezo-electric effect, and that, since the intensity of these fields depends upon the conductivity of the material, regulation of the conductivity may be used to determine the velocity or attenuation of the mechanical wave. In the device shown, piezo-electric transducets 20, 21 are affixed to either end of a crystal 26 of e.g. CdS or ZnO. If the shear mode of propagation is used, it is necessary to orientate the C axis of the delay element in the direction shown in order that the mechanical wave may generate a piezo-electric effect. In the graphs of Fig. 2 the abscissµ represent a variable ##<SP>S</SP>/ 4 ## cgs. electrostatic units where # is angular frequency, #<SP>S</SP> is dielectric constant for constant strain and # is conductivity. Curve 30 shows the variation of the ratio of velocity to minimum attainable velocity and curve 31 shows the variation in attenuation. It is apparent that the device may be used for phase or amplitude modulation or for switching if the delay line is made of a substance whose conductivity is variable, e.g. by light or # radiation-intensity or by change of temperature. A photo-conductive substance such as CdS may be combined in known manner with suitable additives, e.g. aluminium, to obtain peak attenuation or maximum rate of change of phase at a desired operating frequency for a given illumination intensity. In order to obtain a tolerably short response time it is preferred to use incident radiation (for CdS) having wavelengths between 5000 and 7000 . It is apparent from curve 31 that, given a substance whose conductivity remains fixed, the attenuation depends upon frequency and the device may be used as a filter. To increase the number of attenuation peaks, a number of devices may be used in combination or different doping levels and/or different additives may be utilized over different portions of the same delay element. Specifications 958,690, 959,293 and 959,294 are referred to.
