Patent GB-286909-A (GB)
Title: An improved electric switch operating device
IPC: H01H25/06
Filed: 1927-04-14
Abstract: 286,909. Whipp, F., Whipp & Bourne, Ltd., and Mather & Platt, Ltd. April 14, 1927. Electromagnetic switches ; switches, actuating. - A switch-operating mechanism comprises a pair of bellcrank levers the inner ends of which are pivoted together so that they may swing individually about their common pivot to displace a switch arm to one or other of two positions or they can he simultaneously swung about the said pivot and displaced with the pivot as a whole for the operation of the switch arm into its third mid-way position. As shown applied to a remotely-controlled electromagnetically operated switch for use in controlling arms 7, 8 of the bell cranks (Fig. 2) are adjoined by a common pivot pin 9. Normally projections 13, 14 of the arms 7, 8 bear against a fixed stop 15 so that either bell-crank may be pivoted about the pin 9, the corresponding arm 10 moving the switch arm 17 to one or other of its extreme positions. When, however both bell-cranks are operated simultaneously the projections 13, 14 move apart so disengaging the pin 15. The two bell cranks are thereby moved upwardly as a whole to bring the switch arm to its central position as shown in dotted lines in Fig. 3. The bell cranks are pivotally connected at 5, 6 to the cores of operating solenoids 1, 2 and are provided with alternative manual operation by cams on a sliding rod 20 in the manner described in Specification 287,336.
Patent GB-1520174-A (GB)
Title: Multifeed circular knitting machines for producing striped fabric
IPC: D04B15/58
Filed: 1976-03-16
Abstract: The device comprises a rotatably mounted member in the form of a ring (9), the centre of rotation of which is in the longitudinal axis of a needle cylinder (1). The ring (9) is provided with segments or working projections (10, 11) for the alternate actuation of thread guides (2, 3) of at least one knitting system, this ring (9) being connected mechanically to a rearwardly movable member (13, 14) of a drive mechanism (15, 16, 20). This makes it possible to ensure that the striping of all the knitting systems is actuated centrally by means of a relatively simple device. <IMAGE>

Abstract: 727,252. Semiconductor devices. STANDARD TELEPHONES & CABLES, Ltd. April 17, 1953 [April 25, 1952], No. 10456/52. Class 37. A semi-conductor device is manufactured by mounting the semi-conductor body on a metal plate, arranging a metal wire loop substantially parallel to the plate to form a skeleton mould and such that an electrode mounted on the loop contacts the surface of the body, and filling the skeleton mould with a liquid polymerizable insulating compound such as " Araldite " (Registered Trade Mark) to form a solid mass embodying the semi-conductor and the electrode. Fig. 7 shows the metal plate 2 fixed to wires 3, 4, which are fixed to a nickel ring 13. Terminal wires 5 and 6, also fixed to ring 13, are held together by a glass bead 7 and their ends are bent round in two semicircles to form the skeleton mould over plate 2. Two point contact electrodes 9, 10 are welded to wires 5 and 6 and are arranged to contact the surface of the germanium body 11, forming a transistor. After filling the mould with the insulating liquid which is polymerised, the wires 3, 4, 5 and 6 are cut away from ring 13 to provide a transistor as shown in Fig. 1. Alternatively, one of the contacts 9, 10 may be connected to the semi-conductor body by a conducting cement such as that described in Specification 716,243, [Group IV (a)]. The arrangement may comprise an additional electrode, or only a single point contact to provide a rectifier. The insulating material may consist of " Araldite " or a mixture of " Araldite " and alumina, reference being made to Specifications 518,057, 579,698, [both in Group IV], 629,111, 630,647, 630,663, [all in Group IV (a)], and 708,054.

Title: Improvements relating to amplifiers for magnetic transducing heads
IPC: G11B5/00
Filed: 1959-04-01
Abstract: 913,873. Transistor amplifying circuits. TELEFUNKEN G.m.b.H. April 1, 1959 [April 1, 1958; Nov. 8, 1958], No. 11027/59. Class 40 (6). In a multistage amplifier for a magnetic transducing head and in which the first stage comprises a transistor, negative feed-back is provided from the collector circuit of the later stage T2 into the emitter circuit of the first stage T1, by means of resistance-condenser network C4, R4, R5. C4 is chosen so that the feed-back increases with frequency so as to increase the input impedance of the first stage and compensate for the inductive impedance of the transducing head. A further increase in high-frequency response may be obtained by resonating its inductance with shunt capacity C; the effective value of this capacity may be made variable, for adjusting the response, by returning its lower end to the variable tap of a potentiometer connected across resistance R5 (Fig. 4, not shown). The damping due to bias resistor R2 may be made variable by connecting the lower end of this resistor to a variable tap on the resistor R5. The circuit may be stabilized by providing D.C. coupling between the transistors and returning resistor R1 not to the -ve line but to the emitter of transistor T2. In a modification (Fig. 3, not shown), the transducer head is transformer coupled to the transistor T1, one end of the secondary being connected to the base and the other to a base bias potentiometer connected across the supply.
