Title: Magnetic core structure for inductive apparatus
IPC: H01F27/245
Filed: 1964-09-07
Abstract: 1,027,706. Transformer cores. WESTING- HOUSE ELECTRIC CORPORATION. Sept. 7, 1964 [Oct.10, 1963], No. 36538/64. Heading H1T. The four major sides 61, 63, 65 and 67 of a wound laminated core are joined by corner portions 69, 71, 73 and 75, at least the outer periphery of each corner forming at least one straight line joined by bends to the major sides in order that the core will maintain its shape during use. The joints are openable to allow the insertion of coils. The core is constructed by winding a plurality of turns of strip magnetic. material around each other to form a circular structure which is then cut along a radial line to enable the structure to be uncurled, Fig. 16 (not shown). A clamp 161 is then applied and the straight portions 157 are curled around so that their ends abut against the stapped portions 159 forming a circular structure with a desired pattern of stepped lap joints, Alternatively, the circular core is constructed by cutting the individual laminations into suitable lengths, whereby on curling up they form a circular structure with the desired step-lap joints (Fig. 2, not shown). The resulting circular structure is die-pressed into the shape, Fig. 6 (not shown), and then annealed after which it takes the shape shown in Fig. 5. A spreader 82, Fig. 7 (not shown), is placed in the window 70 during annealing to take up stress. If the ends of the laminations form wedge shapes and the joints are formed over the lines 92, 94, Fig. 10 (not shown), the core becomes self-locking and no core band is required. The core may also be built up from individual packets of die-pressed laminations which are then assembled over each other, Fig. 12 (not shown).

Title: Improvements in or relating to electronic pulse generators
IPC: H03K3/30
Filed: 1959-10-29
Abstract: 887,955. Transistor pulse circuits. COLE Ltd., E. K., and SKINNER, M. J. Nov. 16, 1960 [Oct. 29, 1959], No. 36691/59. Class 40(6). A pulse generator comprises a transistor blocking osciliator capable of being rendered fully conductive by a trigger pulse fed to the base and cut off by the output waveform fed back to the base via a delay line. As shown, the PNP transistor T1 is bottomed by regenerative coupling via transformer windings S, P when an external pulse is fed to the base. The collector voltage is delayed by a delay line L before being fed via an NPN emitter follower T3 to the base to terminate the pulse, thus reducing charge storage effects. Feedback resistor R2 is included to minimise the effect of carriers' emitted by the collector of Tl if the delayed voltage drives the collector more positive than the base. Diode D minimises overshoot at the end of the pulse. Fig. 2 (not shown) relates to the output waveform.

Abstract: 970,985. Controlling aircraft. B. M. HORTON. Oct. 26, 1960 [Oct. 26, 1959; Sept. 19, 1960], No. 36810/60. Heading B7G. [Also in Divisions F1, G3, G4 and H4] A fluid amplifier, Figs. 1 and 1A, comprises a sandwich plate construction 11, 12, 13 of metallic, plastic, ceramic or other suitable material in which the central plate has a Y-shaped channel consisting of a power jet supply nozzle 15, a control jet nozzle 16 and two receiving passages 17, 18 connected via bores in the plate 12 to supply and receiving conduits. In the absence of a control jet from the nozzle 16 the main stream from nozzle 15 divides equally into passages 17, 18. On application of a control jet from the nozzle 16 the main stream is diverted to vary the proportions in which the stream is received by passages 17, 18. The arrangement of Fig. 1 may be modified by the provision of a second control nozzle 46, Fig. 2, opposite nozzle 16 so that the main stream is determined by the difference between the pressures of the two control jet streams. This arrangement may be used as a yaw control of a jet aircraft, Fig. 6. The main jet nozzle is connected to the jet exhaust chamber 57 and the two control nozzles are connected to nose orifices 55, 56 and the output passages 17, 18 to wing orifices. If the plane slips in the direction of arrow S the strength of the control jet 16 is increased and the resulting increased flow from the passage 18, 27 produces a reaction in the direction of the arrow R.
