Filed: 1938-08-03
Abstract: 517,683. Electric batteries. PELLINI, J. Aug. 3, 1938, No. 22993. Convention date, Aug. 4, 1937. [Class 53] A battery comprises two electrodes and solutions separated by a porous wall enclosed in a liquid tight receptacle, which is such that when it is inverted the electrolytes are not in contact with the electrodes nor with each other. The receptacle is formed in two halves 1, 2, Fig. 1, held together by a clamping ring 4. In the lower half 1 is a zinc electrode 21 making contact with an external strip 22 and a carbon electrode 13 whose external connection is in the form of a metal rod 16 passing through a liquid tight tube 14 to a terminal 17. The electrolytes for the operation of the cell are separated by a porous pot 8 making liquid tight connection with a flat member 3 separating the upper and lower parts of the container. When the container is inverted the electrolytes pass through holes 10 in the member 3 into the upper half 2 where they are separated by a liquid tight cylindrical partition 9. When used in a hand lamp the container may have a holder 20 for a bulb 19, one terminal of which makes direct contact with the terminal 17, and a handle 24 is provided making pivotal connection with the casing such that the latter may be turned about this pivot when it is desired to transfer the electrolyte from one part to the other. If desired the container may comprise in one block two or more such cells with their terminals externally connected in any desired manner.

IPC: C05B1/02
Filed: 1922-08-24
Abstract: 189,419. Gradl, J. Nov. 22, 1921, [Convention date]. Addition to 184,800. Manures.-Coal or lignite, used for making manure by admixture with catalysts or oxidizing agents, as described in the parent Specification and in Specification 185,729, is prepared for such use by treatments which increase the power of absorbing water. This may be effected by heating the coal or lignite to temperatures below the sintering point, or by treatment with solvents, acids, such as sulphuric or acetic acid, alkalies or superheated vapours. Acids or substances having an acid reaction may be used as additional ingredients in manures made as described in the above-mentioned Specification. Copper salts, with or without ammonium salts, or other substances that contain or give off ammonia, may be used as catalysts in these manures. In one example, steamed coal, manganese dioxide and acetic acid are used as ingredients of a manure; in another example, steamed lignite, acetic acid and copper acetate. In other examples described in the Specification as open to inspection under Sect. 91 (3) (a) the ingredients are powdered peat, ammonium nitrate, raw phosphate and acetic acid, or " humuslignite," copper sulphate, ammonium nitrate and commercial ammonia. These latter examples are not comprised in the Specification as accepted.

Title: Improvements in or relating to the preparation of semiconductor arrangements
IPC: H01L21/314
Filed: 1964-06-04
Abstract: 1,019,527. Masking semi-conductors. SIEMENS & HALSKE A.G. June 4, 1964 [June 5, 1963], No. 23093/64. Heading H1K. A semi-conductor device is prepared by the thermal decomposition of a gaseous compound of a semi-conductor material and the deposition of the material so formed as a layer on at least part of the surface of a heated carrier of semiconductor material wherein a stencil or mask is applied to the surface of said carrier and/or other heated surface to leave portions of the surface uncovered for deposition thereon. The carrier may have at least one PN-junction parallel to the surface to be coated or a heterojunction, i.e. a junction between two semiconductors but of the same crystal structure and lattice constant. The layer deposited may be of different conductivity or conductivitytype to the surface below. The stencil may be of graphite, silicon carbide, metal, the same semi-conductor material as the carrier or a compound of the semi-conductor material, e.g. an oxide or a carbide. The stencil may be coated with the semi-conductor material, e.g. on the side touching the surface. If the stencil or mask is formed from a metal, this may be deposited by spraying or evaporation. If the stencil is a chemical compound of the semiconductor, this may be formed by a chemical reaction with the surface of the carrier or by deposition from the gas phase with or without prior thermal decomposition of the coating composition to give a coating of the desired compound, e.g. CH 3 SiHCL 2  or CH 2 Cl 2 +SiHCl 3  give a coating of SiC. The stencil may have a plurality of apertures which will give discrete layers on the surface thus enabling the finished product to be divided into a number of semiconductor devices of the Mesa type may be made simultaneously. Photo-resist methods may also be used for forming the layer.

Title: Improvements relating to Digital Computers

IPC: G06F11/36
Filed: 1967-05-18
Abstract: 1,192,372. Digital data processing. PLESSEY CO. Ltd. 15 May, 1968 [18 May, 1967], No. 23128/67. Heading G4A. Programme execution in a digital data processing device is stopped on reaching a predetermined instruction address. Towards the end of execution of the current instruction in a microprogramme-controlled computer, the next instruction is read from store and the instruction count is incremented by one in preparation for accessing the nextbut-one instruction. However if manual switches are suitably set, execution of the current instruction in each case is followed by execution of two further instructions (not from the store) before execution of the " next " instruction. The first further instruction decrements the instruction count by one, and the second further instruction (which is actually set up on the manual switches) obtains the difference between the new instruction count and an address field of the second further instruction, and if this difference is zero the computer stops. If non-zero, the " next " instruction referred to is performed, and so on. The second further instruction increments the instruction count by one to cancel the decrementing done by the first further instruction. The invention may be applied to the system of Specification 1,192,371 which is referred to.

Filed: 1936-08-26
Abstract: 463,172. Electric indicators. HOUSTON, R. GOODWIN-. Aug. 26, 1936, No. 23404. [Classes 40 (i) and 118 (ii)] An endless-band indicator is driven by an electric motor under control of relays operated by push-buttons, the relay individual to a push button locking when operated and releasing when its circuit is opened by individual cam contacts controlled by the motor. Release of the relay opens the motor circuit and applies a lock to the motor. When one of the buttons 52-61 e.g. button 52 is operated the corresponding relay 32 of the group 32-41 energizes and locks over its individual cam contact 31. Relays 47 and 42 are energized, relay 47 removing the locking pawl 45 from the notched wheel 43 and relay 42 closing the motor circuit. The motor drives bands 8, which may be on one, two or three sides of the indicator casing and when the required indication is being exposed through windows 12 the relative cam 25 operates spring-pressed lever 26 and opens contact 31 so that the relay 32 releases. Relays 42 and 47 fall away to open the motor circuit and to relock the indicator bands respectively. The bands may be illuminated by lamps 62 and a lamp 64 may illuminate the control panel. The bands 8 are provided with perforated edges which co-operate with projections 7 on the rollers 1, 2, 3, 4, 5 and 6. The indicator is suitable for use as a manoeuvre indicator for vehicles, signs such as STOPPING, PASS, LEFT, RIGHT, &c. being printed on the bands 8, or as a road signal for controlling traffic.
