Title: Electrical wiring systems
IPC: H01R25/16
Filed: 1942-01-27
Abstract: 555,217. Two-part couplings. O'BRIEN, J. F. Jan. 27, 1942, No. 1128. [Class 38 (i)] In a wiring system having a moulding 10 formed in unit lengths having male and female ends 11, 12 to fit adjacent units together, three conductors a, b, c are mounted forming a threewire system providing supplies at 220 volts and 110 volts. The conductor a constitutes the neutral wire while the conductors b, c provide the 220 volt supply. A three socket outlet 22 has its contacts so arranged that only a standard 220 volt three contact plug can be inserted. A two contact outlet 23 is supplied from the neutral conductor a and one of the conductors b, c which is cranked to bring it into proximity to the conductor a. The conductors are supported in slotted partitions 20 that co-operate with insulating spacers 21. Specification 555,239 is referred to.

Title: Improvements relating to the fibrillation of tapes of thermoplastic materials
Inventor: MACKIE GORDON
IPC: B29D28/00
Filed: 1968-01-09
Abstract: 1,244,982. Apparatus for fibrillating tapes of thermoplastic material. JAMES MACKIE & SONS Ltd. 8 Jan., 1969 [9 Jan., 1968], No. 1310/68. Heading B5B. Apparatus for fibrillating tapes of longitudinally molecularly oriented synthetic organic thermoplastic material includes a roller provided on its peripheral surface with axially extending rows of pins, the pins in alternate rows being shorter than those in the intervening rows and each of the longer and the shorter pins being mounted at an angle to the line extending radially from the axis of rotation of the roller through the point where the pin is attached to the periphery of the roller, the angle being in the plane, the angled pin lying in a plane normal to the axis of rotation of the roller and deviating from the above line in a direction opposite to that in which the roller rotates when the apparatus is in operation, the circumferential spacing between the alternate rows of longer and shorter pins and the difference between the lengths of the pins being such that a tape fed into contact with the roller when the roller is rotating is pierced simultaneously by pins in pairs of adjacent rows. The pins in all the rows may be inclined to their respective prolonged radii at the same angle, which may be about 30 degrees. Each row of shorter pins may be closer to the following row of longer pins than to the preceding row of longer pins considered in relation to the direction of rotation of the roll in operation. As shown in Figs. 2 and 3, a pinned roller 5 is driven in anticlockwise direction at a peripheral speed considerably greater (e.g. twice to three and a half times as great) than the linear speed of the tape 1. The pins on the roller 5 are mounted at uniform spacing in axially extending rows 15 and 16 as seen in Fig. 3 with the pins in one row immediately in line with those in the preceding row when viewed in a circumferential direction. The pins in the rows 15 are somewhat longer than those in row 16 and the rows 16 are closer to the rows 15 which follow them in the direction of rotation than to the rows 15 which precede them in the direction of rotation. As a result of the combination of the relative lengths and relative spacings of the pins in the rows 15 and 16, the tape 1 is pierced substantially simultaneously by pins in the two rows as shown in Fig. 2.

Title: Data processing apparatus
IPC: G06F9/38
Filed: 1970-01-12
Abstract: 1282341 Data processing INTERNATIONAL BUSINESS MACHINES CORP 12 Jan 1970 [15 Jan 1969] 1358/70 Heading G4A In stored-program data processing apparatus, switching to another instruction stream as a result of a successful conditional branch instruction occurs after execution of a marker instruction. Instructions are accessed from memory and inserted into the top of a multi-instruction pushdown buffer together with bits indicating, for each instruction, whether or not it is a target, branch or exit instruction. The target bit is provided at the memory (see below) and the branch and exit bits are derived by a predecoder. The instruction at the bottom of the buffer is decoded. If it is a branch instruction, two fields in it select two bits from a condition register and 1 of 8 logical functions of these specified by part of the op code is evaluated in a function generator to determine whether the branch should be taken, the branching being to an address obtained by adding a field from the instruction and the contents of one of a plurality of registers selected by another field of the instruction. However, the sequence of instruction fetching branches to this address only when the next exit instruction enters the buffer. The branched-to instruction has its target bit set to 1 at the memory. Decoding and therefore execution of each instruction in the buffer between the exit instruction and the target instruction is inhibited, the inhibition terminating when the target instruction is shifted into the bottom position of the buffer, in response to the target bit of 1. Decoding of any branch instruction after a successful branch instruction and before the next exit instruction is also inhibited. If both an exit and a branch instruction are present in the buffer but a successful branch has not been determined, instruction fetching is suspended until not all these conditions exits, thus awaiting the result of the branch test. Instruction fetching is from the next sequential address if there is no exit instruction in the buffer, and if there is but there is neither a branch instruction in the buffer nor an indication of a successful branch determined.

Patent GB-674163-A (GB)
Title: Improvements in or relating to the sealing off of exhaust tubes of electric discharge tubes
IPC: H01J9/40
Filed: 1949-01-19
Abstract: 674,163. Electron discharge apparatus. PHILIPS ELECTRICAL, Ltd. Jan. 19, 1949 [Jan. 22, 1948], No. 1488/49. Class 39 (i). A device for sealing off the exhaust stem 4 of an electric discharge tube so that the seal-off pip is shorter than, and so protected by, the projecting base-pins 3 comprises a two-part metal holder 5, 7 containing narrow tapered slots extending between the base-pins, through which the sealing flames are guided. The operation may be divided between successive stations, Figs. 1 and 3, of a rotating turret machine. The holder 5, 7 is bolted to an arm 6 secured to a stay-rod 11, the latter ending in a roller 14 passing over a guide 15. This guide is pivoted at 16 and urged upwards by a spring 17. The parts of Figs. 1 and 3 below the line X-X have been turned through 90 degrees to provide a clearer illustration. Slots 19a are separated by a perforated partition 20 from slots 19b, and initially, gas-oxygen flames are directed from burners 21 through slots 19a to heat the exhaust stem 4, as in Fig. 1. The stem is gripped in a vacuum stop-cock 12 and retains the tube, holder and its associated parts against the spring 17, so that as the stem 4 softens, tube, holder, &c., move upwards, drawing the stem out into a capillary. The partition thus passes above the burner flames, as in Fig. 3, and protects the glass parts above it from the heat of the final burner 22 now directed down a slot 19b. In the modification shown in Fig. 9 a perforated screen 24 surrounding the exhaust tube distributes the heating flame more evenly, to reduce risk of sucking-in. In this case the tube is drawn upwards only after the seal-off. The speed of sealing is sufficient to allow exhaustion of 1000 tubes per hour. Specification 559,753 is referred to.

Cushioning in the chamber a, and therefore the force of the blow, is varied by means of a handoperated valve j<1>, adapted to close more or less the port j, and at the same time to release air under pressure through ports i<1>, which air acts to blow away dust. The relative sizes of the two cylinders are as indicated in Fig. 1.
Patent GB-347620-A (GB)
Title: Improvements in the manufacture and production of unsaturated hydrocarbons
IPC: C07C27/10
Filed: 1930-01-17
Abstract: Liquid unsaturated hydrocarbons are obtained by oxidizing liquid or solid paraffin or naphthene hydrocarbons, if desired in the presence of catalysts such as barium cinnamate, uranyl tungstate, or manganese naphthenate, the resulting oxidation products, containing alcohols, hydroxy-acids, esters, lactones, aldehydes, ketones or other oxygenated compounds or mixtures thereof, being then subjected to such high temperatures, preferably in the presence of catalysts, that water and/or carbon dioxide are split off.  The splitting off of water is effected at temperatures above 150 DEG  C., preferably above 180 DEG  C.  The oxidation may be effected in the gaseous or liquid phase, for example with gases containing oxygen, such as air, or those supplying oxygen, such as nitrogen oxides, at atmospheric or other pressures, and the oxidizing reaction may be conducted in a definite direction by the employment of specific catalysts, e.g. with boric acid or vanadium pentoxide as catalyst, the production of alcohols is increased.  The alcohol content of the product may be increased by hydrogenating the aldehydes and ketones.  The crude oxidation product may be worked up by heating or distilling, possibly in the presence of dehydrating catalysts, e.g. phosphoric acid to obtain unsaturated hydrocarbons, in addition to unchanged saturated hydrocarbons and fatty acids.  Or the oxidation product may first be treated, with alkali for example, to remove the acids, the residue being worked up as before.  Or the various oxygenated constituents may be separated before conversion to unsaturated hydrocarbons.  Thus the residue obtained by the protective distillation of the crude oxidation product or of the acid constituents separated therefrom, carried out for example with steam, carbon dioxide, inert gases or vapours, with or without a vacuum, may be converted into unsaturated liquid hydrocarbons by a further distillation at ordinary or increased pressure.  The formation of hydroxyacids may be promoted by means of iron; they occur, together with such derivatives as lactones, in the residue from extractions with petroleum ether, and they should be decomposed at ordinary or increased pressure and in the presence of pumice, finely divided copper, nickel, or the like, as these catalysts assist the splitting off of both water and carbon dioxide.  Examples are given, in which the separation of the unsaturated hydrocarbons by treatment with sulphur dioxide after the removal of acid constituents is described.

Title: Process for the preparation of polyfunctional diazonium phosphates
IPC: C07F9/06
Filed: 1962-01-18
Abstract: A polyfunctional diazonium acid phosphate free from metal salts is prepared by condensing a substituted or unsubstituted diphenylamine-4-diazonium salt of an acid which boils at a temperature below 150 DEG  C. with formaldehyde in phosphoric acid, removing the anions of the diazonium salt from the reaction mixture as the corresponding volatile acid prior to or after condensation, and precipitating the polyfunctional diazonium acid phosphate formed by the condensation by addition to the reaction mixture of an organic liquid in which the polyfunctional diazonium acid phosphate is sparingly soluble and which readily dissolves water and phosphoric acid.  In a modification of this process a substituted or unsubstituted diphenylamine-4-diazonium salt is condensed with formaldehyde in a mineral acid other than phosphonic acid, the condensation product is converted into the salt of an acid boiling at a temperature below 150 DEG  C. if not already present as such a salt, the condensation or conversion product as the case may be is dissolved in phosphoric acid, the anions of the diazonium salt are removed from the solution so obtained as the corresponding volatile acid and the resulting polyfunctional diazonium acid phosphate is precipitated by means of an organic liquid having the characteristics specified above. The anions may be removed by passing a current of dry air or other non-reactive gas through the reaction mixture.  The precipitation may be carried out by diluting the thick condensation product with the organic liquid, e.g. dimethyl formamide, dimethyl sulphoxide or a C1- 4 alcohol, and introducing the suspension in a thin stream with vigorous stirring into a large quantity of another organic liquid in which water and phosphoric acid are readily soluble but in which the acid phosphate is sparingly soluble.  The acid phosphates may be converted into the neutral phosphates by treatment with an anion exchanger.  The benzene rings of the diphenylamine-4-diazonium salt may be substituted by chlorine atoms or methoxy, ethoxy, ethyl or carboxy groups, and specified salts are the chloride, bromide and sulphate.
