Title: Improvements in electronic switch devices
IPC: H03K17/82
Filed: 1963-01-25
Abstract: 1,021,861. Bi-stable magnetic devices. COMPAGNIE FRANCAISE THOMSONHOUSTON. Jan. 25, 1963 [Jan. 26, 1962], No. 3231/63. Heading H3B. Each of two ferrite core structures which together form a magnetic toggle comprises an outer and a central ring linked by two diametrically-opposite arms, both outer rings being encircled by two separate control windings, and the central rings carrying at least one transformer primary winding and separate secondary windings. The two structures have rectangular hysteresis characteristics and are superimposed with an intervening spacer also preferably of ferrite material. In one arrangement, Figs. 2 and 3, the arms 123, 133 of the two superimposed structures 12, 13 are orthogally arranged, and each control winding 21, 22 and 23, 24 comprises oppositely wound halves a, b and c, d located on either side of a structure arm. When one control winding, such as 21, 22, is pulsed it establishes a saturating flux through the arm 133 which it straddles and through the central ring. Consequently, the other central ring becomes unsaturated since its arms are subjected to opposed fluxes and an A.C. output is induced in the associated secondary winding So from the primary winding P. When the other control winding is pulsed the flux conditions of the two structures are reversed and an A.C. output is obtained from the other primary winding. An alternative embodiment is shown in Fig. 4 in which the arms of the two superimposed structures are parallel and the primary winding on the central rings comprises two separate coils T1, T2, coil T2 having the larger number of turns. The two structures are saturated in the same sense when a control winding 21, 22 or 23, 24 is pulsed, the flux being unidirectional through the arms and the two halves of each central ring in a direction dependent on which control winding is energized. The two primary coils T1 and T2 are pulsed alternately, and if control winding 21- 22 is pulsed then the alternate pulses in coils T1 and T2 repeatedly switch the lower structure shown only. On the other hand, if the control winding 23-24 is pulsed, the upper structure is switched repeatedly by the pulses in coils T1 and T2. Only the structure which is switched causes an output to be induced in the associated secondary winding S. The pulses in coils T1, T2 may have a frequency in the order of 10 kc/s. and a duration of only a few Ás.

Filed: 1945-02-10
Abstract: 588,856. Moulding bricks. WHITTAKER & CO., Ltd., C., and WHITTAKER, N. Feb. 10, 1945, No. 3400. [Class 87 (ii)] A scraper. F carried by the reciprocating feed carriage A enters the mould B to a desired depth and on the rearward movement of the carriage removes a layer of material from the top, or from a portion of the top, of the material in the mould. In Fig. 1, the scraper F is carried on arms f fast on a transverse shaft E, on which are also fast arms g having at their ends rollers G running on fixed rails G<1>. As the carriage moves forward the rollers drop on to the surface g<1> lowering the scraper on to the top of the plunger D; when the carriage is fully forward and the plunger D descends, the scraper enters the mould and, on the return of the carriage, removes a top layer of material, being carried out of the mould at the end by the surface g'. The thickness of the layer is controlled by adjusting the screwed rod H, which forms a stop for the arms g<4> on the shaft E. In a modification the scraper is withdrawn from the mould by an electromagnet controlled by a switch operated by the backward movement of the carriage. To remove material corresponding to the recessed panel of a frogged brick, the scraper is made of width equal to the width of the panel and is arranged to enter and leave the mould at positions coinciding with the ends of the panel. For tapered bricks the scraper F, Fig. 5, is mounted on a shaft L working in slots a in the carriage, and having rollers M running on inclined fixed girders M' so that material above the dotted line b is removed. The scraper is pivotally mounted on the shaft and pressed into the vertical position shown by a spring l which yields to allow the scraper to trail over the' surface of the plunger D during the forward movement of the carriage. The table P on to which the compressed blocks Rare ejected may be inclined so that the tops of the blocks are horizontal as they travel along the table. A difference in density between the bricks made in a duplex machine can be remedied by adjusting the scraper on one of the feed carriages.
