Title: Improvements in or relating to the repair or renewal of electric incandescence lamps
IPC: H01K3/30
Filed: 1919-06-18
Abstract: 152,716. Harrison, F. June 18, 1919. Repairing.-In renewing a lamp, a tungsten wire which has been wound on a mandrel and stretched to a suitable length is inserted through an aperture B at the pip end, secured by spring clips F to the leading- in wires and wound over molybdenum or other metal hooks E having glass or other fusible bases, which have been previously secured to the bulb. An exhaust tube is then fused over the aperture B. There may be several hooks E in a plane transverse to the axis of the bulb, and the leading-in wires may be extended downwards so that the whole of the filament lies in this plane. When the original lamp contains a central support rod, the whole or the lower portion of it is removed. The leading-in wires D may be bent outwards, as shown, to prevent " blue fog." By using a suitable length of wire, a lamp may be adapted for a higher voltage than that for which originally intended. The diameter of the wire coil may be about six times that of the wire itself. Specifications 26289/12, 12054/13, 22024/13, 29981/13, 114,464, and 152,378 are referred to.

Abstract: 475,909. Coin - freed article delivery apparatus. FITZPATRICK, H. J. (Maatschappij van Berkel's Patent N. V.) June 2, 1936, No. 15368. [Class 27] Articles stored in rows.-Articles are stored upright in horizontal rows in receptacles 2 arranged in one or more vertical columns : each receptacle has means, such as a conical spring 4, for holding the articles against a front stop, and an ejector for discharging the foremost article sideways into a common shoot extending alongside the vertical column of receptacles, blocking members allow only one ejector at a time to be operated, and coin-freed mechanism controls operation of all ejectors. As shown, the receptacles 2 are arranged in two vertical columns. Ejector fingers 7 are carried by arms 22 secured to sleeves 8 loose on a pair of stationary rods 12. Further sleeves 13, axially slidable but non-rotatable on the rods 12, are interposed between the ejector sleeves 8, and the engaging end faces of all the sleeves are inclined so.that actuation of any ejector causes its sleeve and all sleeves above to rise. Cooperating with the end sleeves on the two rods are limit stops 16 and 17 at either end of a centrally pivoted bar 14 whereby only one ejector in the apparatus can be actuated at a time. Secured to each ejector sleeve 8 is an arm connected to a draw-rod 9 provided with an external operating knob 10 whereby the ejector can be actuated against the action of a a return spring 11 to discharge the foremost article in the associated receptacle sideways into a common central delivery shoot 28. Each ejector arm 22 is connected by a link 21 to a respective slide 20 having a cam-shaped end engaging under a pin 19 on a common coinfreed bar 18 which prevents operation unless a coin has been inserted. The lower end of the delivery shoot 28 is closed by a hinged door 29 provided at the rear with a pocket to accommodate the article discharged, and an arcuate plate serving to close the end of the shoot when the door is opened to obtain the article. Casings.-The front wall 32 of the apparatus is of glass or other transparent material, or of perforated material, so that the foremost articles in the receptacles can be inspected, and the ejected article is visible as it passes to the delivery pocket. Coin action, mechanical-connection.-The bar 18 is connected by a bell-crank to a slide normally locked by a detent. An inserted coin is received by a pocket in the slide and disengages the detent therefrom during the upward movement of the bar 18 upon actuation of an article ejector.

Title: Improvements in or relating to synthetic resins
IPC: C08G8/28
Filed: 1932-05-31
Abstract: A phenol and a reactive carbonyl compound are reacted to yield a fusible resinous condensate which is then reacted with a partial ester or partial esters of a polyhydric alcohol and one or more fatty acids of high molecular weight obtainable upon hydrolysis of an oil or fat in the presence or absence of a natural resin compound to yield a mixed condensate wherein the phenolic condensate constitutes more than 15 per cent of the product. Suitable phenols include phenol, cresol, resorcinol, naphthol and diphenyl hydroxide and suitable resin compounds include rosin and ester gum.  Phenol and formaldehyde are condensed in the presence of a partial linoleic acid ester of glycerol and of rosin and preferably in the presence of a metal compound such as zinc oxide, hydroxide or abietate to yield an oil-soluble product.  In examples: (1) phenol, formaldehyde, rosin glycerol ester, zinc resinate and glycerolmonolinoleate are condensed together; (2) a mixture of rosin and ester gum replaces the rosin glycerol ester gum in example (1); (3) zinc acetate replaces the zinc abietate used in example (1) (4) p-phenylphenol replaces the phenol used in example (1); (5) p-phenylphenol, zinc acetate, formaldehyde are reacted together and then heated with glycerol monolinoleate and rosin ester gum; (6) phenol, formaldehyde and glycerol monolinoleate are condensed together preferably in the presence of zinc acetate.

Title: Data selection system
IPC: G06F17/30
Filed: 1959-05-05
Abstract: 909,107. Electric digital data-storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 5, 1959 [May 5, 1958], No. 15402/59. Addition to 868,644. Drawings to Specification. Class 106 (1). The apparatus of the parent Specification is provided with means for setting up on a plugboard means to detect a predetermined group of characters and thereby causing a predetermined read-out operation from the tape. A character is read from the tape in 6-bit form, stored in a register and transferred to a six-to-twelve translator from which the output is the character in Hollerith code, which output energizes tape emitter hubs representing the character read. As described in the parent Specification a tape block column counter assigns a number to the column (lateral of the tape) in which a character written usually from 1 to 80 corresponding to the record cards providing the machine input and output. Two kinds of search may be initiated. Fixed field and Floating word. In the first characters in specific columns are searched: e.g. A in column 4 of a record in conjunction with B in column 5. This is initiated by plugging the tape emitter hubs representing the characters to be found into AND units, described in the parent Specification, the other inputs being the signals emitted by the counter on reaching the required columns. In a floating word operation a specific group of characters, or alternative groups e.g. SCREW or BOLT, are searched for in any position. To do this in the example given the letters S and B are plugged into separate AND units from the tape emitter hubs in such a way that on the sensing of either of these the counter is set to zero. The letters C, R, E, W are plugged in associated with columns 1 to 4 respectively and the letters O, L, T with columns 1 to 3 respectively. On finding a group of characters by either method of search the tape is stopped, reversed to the beginning of a record block and the record read into magnetic core storage for subsequent processing, all as described in the parent Specification.

Title: Data processing apparatus
Inventor: AUSTIN PHILIP CHARLES
IPC: G06F9/22
Filed: 1970-04-03
Abstract: 1,262,248. Data processing. INTERNATIONAL BUSINESS MACHINES CORP. 3 April, 1970, No. 15867/70. Heading G4A. Data processing apparatus includes a central processing unit having instruction fetch and execution phases for each instruction, microprogramme control means, hardware control means, and means for determining whether the instruction fetch and/or execution phases are to be controlled by the microprogramme control means or the hardware control means or by a combination of the two control means. A main store holding operands, instructions and microinstructions is provided, together with an auxiliary store and a work store. Normally instruction fetch is controlled by the hardware control means (sequencers) totally for some instructions, partially for other instructions (requiring two storage accesses for operands) and not at all for yet further (more complex) instructions, the microprogramme control means being used otherwise. However, a failure or check condition (e.g. instruction address not on an integral boundary) causes instruction fetch to be repeated, or the condition analysed, under microprogramme control in every case. Execution of the more frequently used instructions is normally under hardware (sequencer) control and of the less frequently used (e.g. convert to binary or to decimal) under microprogramme control, but an unusual condition requiring analysis, or a failure in the hardware control, causes control to pass to microprogramme e.g. to repeat the instruction execution, the microprogramme controls being capable of controlling execution of any instruction. The main store address register has a back-up register for a microinstruction address, this register being fed from the address register, and feeding the address register with or without incrementing by 1 or 2. A particular microinstruction in a microinstruction control register loaded from main store is decoded to transfer instruction fetch control from microprogramme to hardware sequencers. The same decoder performs the same function for execution. A microprogramme start address is forced into the main store address register to cause transfer from sequencer to microprogramme control. Multiplication uses multiples of the multiplicand by 1, 2, 3 and 6 (or 4) obtained in succession in the auxiliary and work stores by addition of previous multiples in the series. Division uses multiples by 1 and ¢. The work store has respective portions allotted to the ALU, I/O adaptors, and system reset and log out, and can store, inter alia, status of seven interrupted microprogrammes.
