Abstract: 950,592. Semi-conductor devices. TELEFUNKEN A.G. Feb. 19, 1960 [Feb. 19, 1959], No. 5882/60. Heading H1K. A semi-conductor diode or transistor has an insulating envelope coated with a conductive material which is conductively coupled to one of the electrodes of the device, e.g., in the case of a transistor, the base electrode. The conductive coating may be on the inside or the outside surface of the envelope, and may be opaque. As described, static charges on the surface of a semi-conductor body in such a device are removed by heating the semi-conductor or by bombarding it with charge carriers of sign opposite from that of the static charges. In one example, a semi-conductor device in a hermetically sealed envelope is heated at 100- 120‹ C. for 1-2 hours. In another example a similar device comprising a semi-conductor having positive static charges is bombarded with #-rays. The conductive coating of the envelope is said to inhibit the formation of further static charges.

Title: Improvements in dry cell and battery and method of making the same
IPC: H01M50/147
Filed: 1942-05-08
Abstract: 555,047. Galvanic batteries. BURGESS BATTERY CO. May 8, 1942, No. 6261. Convention date, April 30, 1941. [Class 53] A dry cell includes a metal can open at one or both ends and containing the active mass, the end or ends of the can being closed by a body consisting wholly of sealing material which forms one wall of an empty expansion chamber at the end or ends of the cell. The sealing material is not supported by a washer, thus reducing cost and avoiding short-circuiting owing to saturation of the washer by electrolyte. The seal is effected by lowering the open end of the can into the fluid sealing material. As shown a battery is formed of cells in an outer container composed of two tray-like members 2, 3, which may be of paraffin-impregnated cardboard. The cells are formed of open-ended metal cans containing the active materials which fill them except for spaces 11, 12 at the ends which form expansion chambers for the evolved gases. They are covered with insulating jackets formed of a preferably somewhat elastic material, suitable materials being that known under the Registered Trade Mark " Pliofilm," a rubber hydrohalide, rubber, ethyl cellulose, " Parafilm," and polystyrene. In making the battery, the cells are assembled in a suitable form, for which purpose the tray 2 may be used, the inter-cell connections are made, and the whole block is inverted and lowered as shown in Fig. 3 into the tray 3, which contains a shallow body of fluid sealing material 7. This is forced up around, and into the ends of the cells, which are thus sealed, the air pressure preventing the material from filling the spaces 12. After the sealing material has cooled the form or the tray 2 is removed and the block of cells is inverted and lowered into fluid sealing material in a tray 2, so that the other ends of the cells are similarly sealed. Alternatively, the fluid sealing material may be contained in thin paper liners supported by suitable forms, the paper either being removed before placing the battery in an outer covering, or retained; or, the individual cells may be assembled by inserting them individually in a tray which is to form part of the permanent covering and contains sealing material maintained in a fluid condition until all the cells are in position. In another form, the tops of the cells are sealed by pouring the sealing material directly on to the top of the active material, gas spaces being provided only at the bottom by sealing the lower ends as above described. The insulating jackets may extend beyond the ends of the cans, so that the gas spaces are formed within the jacket extensions, and if elastic jacket material and plastic sealing material be employed the gases will, under excess pressure, escape into spaces formed between the metal can and the jacket by stretching the latter. Specification 531,379 is referred to.

Title: Improvements in start-stop telegraph transmitters
IPC: H04L17/06
Filed: 1932-03-04
Abstract: 397,923. Type-printing telegraphy. CREED & CO., Ltd. and GRIFFITH, R. G., Telegraph House, Croydon. March 4, 1932, No. 6522. [Class 40 (iii).] In a keyboard-controlled transmitter for a start-stop telegraph system in which a start element precedes a number of permutation selecting elements, means is provided, operable on depression of a character key-lever, to introduce a delay before the operations for the transmission of the start and permutation elements are effected. On the depression of a key-lever an arm 8 releases a cam sleeve 2 connected by a friction clutch 4, 5 to a shaft 1 driven by a motor (not shown) Immediately after the sleeve 2 is set into rotation an arm 20 co-operating with a cam 13 locks the keyboard against further key operation, and after either of the teeth 9, 10 has passed a detent arm 16 a cam arm 12 drops into a recess of the cam 13 and moves a detent 7 out of engagement with a tooth 6 on a cam sleeve 3 which is positively clutched to the shaft 1 and effects the transmission of the impulse combination set up by the key. During the major portion of the revolution of the sleeve 3, a cam 14 co-operates with an arm 15 on a sleeve 17 which carries the detent arm 16 arranged to arrest, in some cases, the cam sleeve 2 by engaging either of the teeth 9, 10. If the arm 8 is again operated by a key-lever before the cam sleeve 3 has completed or nearly completed its revolution,-that is, transmitted the previous signal,-the tooth 9 or the tooth 10 rotates past the arm 8, but is engaged by the arm 16 to arrest the cam sleeve 2. When the sleeve 3 has completed its revolution the arm 15 co-operates with cam 14 to raise the detent arm 16 clear of the tooth engaged, and when the cam 13 continues its rotation, the cam arm 12 again drops and releases the cam sleeve 3 for a further revolution. The arms 12, 20 are operated twice per revolution of the cam 13 on the sleeve 2. A modification of the invention is shown in Fig. 2, which is identical with the figure of Specification 388,785. The depression of a key lever 30 actuates a universal bar 37 which releases a shaft 2 carrying a cam 13. The lever 20 locks the keyboard and a lever 12 releases a cam-shaft 3 which during rotation transmits start, stop and signal impulses. If a subsequent key is depressed before the previous signal has been transmitted, the arm 16 operated by cam 14 arrests the rotation of the shaft 2 before the signal combination is transferred to the setting members 38..42. When the shaft 3 has completed its rotation the cam 14 raises the arm 16 to release the shaft 2 for the continuation of its rotation. In a modification, the start impulse is preceded by a stop impulse of the opposite character to provide a greater time for subsidiary operations-such as the transfer of the settings of the permutation bars -after depression of a key-lever.
