Filed: 1968-09-23
Abstract: 1,248,773. Transformers. J. MARLOW. 23 Sept., 1968 [2 Oct., 1967], No. 45045/68. Heading H1T. [Also in Division G1] A displacement transducer comprises a ferromagnetic core 11 which includes two overlapping limbs 19, 21 circumscribing the latter of which is a movable short-circuited conductor, 57, mechanically connected to a movable device 35 and between which is an air gap 43. The core is energized from an alternating source 23 by a primary winding 59 in series with the primary 61 of a transformer 63. Movement of the conductor along the flux density gradient causes a variation of opposing magnetomotive force which varies the voltages induced in differential secondary windings 65, 67 and generates a displacement dependent difference voltage which is sensed by a readout device, 69. Alternatively a displacement may be measured from variations of voltage induced in a secondary winding 71. A second displacement may be measured using an additional conductor 22 on the other limb 19. In the embodiment of Fig. 2 the two limbs are arcuate so that short-circuited conductors 109, 110 connected to a rotatable shaft 111 give. a measurement of angular displacement (over a range which is less than 360 degrees) on a readout device connected between terminals 132, 133. A permanent magnet 112 coupled to the shaft induces a voltage, which is a linear function of angular velocity, in a secondary winding 115 wound on a third limb 93, 94, 95, connected to form a continuous flux path with the two arcuate limbs. The embodiment shown in Fig. 3 uses limbs 118, 119 which are concentric annuli and are connected by a limb 120, 121, 122. Angular displacement of a shortcircuit conductor 126 coupled to a rotatable shaft 115 is indicated by variations of voltages induced in differentially-connected secondary windings 129, 130 when the primary winding 123 is energized from an alternating source.

Abstract: 1,124,165. Making transformers. WESTINGHOUSE ELECTRIC CORP. 10 Oct., 1966 [22 Oct., 1965], No. 45181/66. Heading B3A. [Also in Division H1] Pressure rings 22 (Fig. 1) for transmitting pressure from clamping means 30 to clamp the coils 20 of a transformer (see Division H1) are formed of wound metal strip bent to V-shape cross-section (Fig. 4) to prevent the rings from telescoping during winding. Each ring is formed by winding cold rolled grain-oriented or hot rolled non-oriented magnetic strip on a mandrel until the desired diameter is reached, then the ring is secured by spaced radial welds 38 and annealed. A radial out is made through the ring, the cut edges etched to remove burrs, then the gap is filled with epoxy resin 40 to prevent the ring from acting as a shorted turn. Epoxy resin is also brushed on both sides of the ring, penetrating between the convolutions, and several layers of polyester- or epoxy-glass or other high tensile tape may be wrapped around the circumference of the ring to further secure the ring and to prevent the convolutions from splitting.

Abstract: 997,449. Automatic control of aircraft. BENDIX CORPORATION. Nov. 18,1963 [Nov. 19, 1962], No. 45477/63. Heading G3R. In a system of A.C. signal limiting by means of rectifiers, a gradually increasing control voltage derived from a D.C. source is applied to gradually increase the limiting value and the control voltage is adjusted in dependence on the magnitude of the A.C. signal. In Fig. 2, by operating a switch 100 to a position opposite to that shown, A.C. signals from a radio or other directional reference 104 are applied to an aircraft automatic pilot 206 through a limiter circuit 90 of the type described in Specification 892,509. The operation of switch 100 also connects a source 101 to charge a condenser 5 and thereby gradually raise, through an amplifier 103, the limiting value of signals passed by limiter 90. The limit is thus raised to a maximum value at which it remains until the A.C. signals fall below a predetermined value to energize a relay 200 through a transistor Schmitttrigger circuit 202 whereupon connection of a resistor 225 discharges condenser 5 and thereby reduces the limit to a low value. Thereafter any increase of the A.C. signals above the predetermined value is effective to de-energize relay 200 and gradually increase the limit to its maximum again.

In a preferred embodiment for bonding a polypropylene sheet 12 to a nylon eye fastener 14, layer 22 is of polypropylene, layer 24 is of nylon and the strands 27 constitute an open-weave glass fibre fabric. One or both of layers 22, 24 may be rendered susceptible to heating by high-frequency magnetic or dielectric heating by incorporating magnetic particles, e.g. Fe 3 O 4 , gamma-Fe 2 O 3 . CrO 2 , or dielectric particles, e.g. polymers and copolymers of vinyl or vinylidene chloride or fluoride. The particulate material may be incorporated by calendering and or extrusion. As shown, particulate material 28 is present only in the layer 24 having the higher heatsealing temperature. The strands 27 may be so embedded that the layers 22, 24 are spaced apart or contacted in the fabric interstices. Contact may be improved by coating the weft and warp with the materials of layers 22, 24 before the fabric is woven. The embodied material is made by softening the layer 22 on a heating plate or by indirect energy, applying the fabric of strands 27 with pressure if necessary, and applying the layer 24 as a melt or solution by casting, extrusion, spraying or brushing. If desired, both layers may be applied as softened solid layers or both in liquid or solution form. The material may be hotpressed to reduce its thickness. One or both of layers 22, 24 may be pigmented. Other suitable materials for the layers are listed, and the woven fabric may be replaced by a roving or knitted fabric.

Abstract: 1,125,317. Counting-apparatus. COULTER ELECTRONICS Ltd. 27 Oct., 1965 [13 Nov., 1964], No. 45592/65. Heading G4D. The quantity of material in each range of particle size is estimated by counting the number of particles in a range and multiplying by the average size of a particle in that range. In a system in which particles passing through a restriction affect the resistance between electrodes the resulting pulses are amplified and pass to appropriate pulse-height discriminators 24, the outputs of which are passed to counters 26 with appropriate division (or multiplication) to compensate for the differences in particle size. The system shown in Fig. 3, by energizing a number of channels up to the highest appropriate to the particle concerned, produces registrations in the counters corresponding to curve 14, Fig. 2. The registrations in the counters may be differenced to produce the equivalent of curve 16 on another set of counters. In a modification (Figs. 6, 9, not shown) the sample is tested for increasingly larger particles for increasingly smaller times so that the quantities registered in these times represent the distribution over the specified ranges.

Abstract: 1,058,499. Transistor monostable circuits. PHILCO CORPORATION. Nov. 9, 1964 [Nov. 8, 1963], No. 45655/64. Heading H3T. In a transistor monostable circuit of the crosscoupled type the input transistor is maintained normally conducting to render it less sensitive to noise and is connected to the other transistor through a timing circuit and a diode which maintain the latter transistor normally non- conductive. A positive input pulse at 31 cuts off transistor 10 and the rise in collector potential causes diode 25 to cut off so that bias current through resistor 25 renders transistor 22 conductive and through connection 36 maintains transistor 10 cut off. Capacitor 15 charges at a rate determined by the setting of a resistor 18 until diode 25 again becomes conducting whereupon the circuit reverts to its original state. The bias supplies are stabilized by Zener diodes 14 and 21. Reference has been directed by the Comptroller to Specification 990,645.
