Abstract: 1000259 Electric radiant space heaters GENERAL ELECTRIC CO Ltd 12 Oct 1962 [13 Oct 1961] 36813/61 Headings F4W and W45D A radiant heater having a rod or tube element mounted with a reflector in an elongated casing includes a detachable face guard for the casing, the element being supported by arcuate spring clips on the face guard, whereby the guard and the element can be handled as a single unit during assembly, although the element is readily detachable from the guard. Element 1, constituted by a resistance wire 2 in an open-ended silica tube 3, is mounted near its ends on the face guard 7, which is screwed to the casing 5 by a pair of thistleshaped spring clips 9 which grip ceramic ferrules 8 slid over the tube 3, and is supported at intervening points by the slatted plates 12 also fixed to the guard. A chromium-plated circular or parabolic reflector 4 may be mounted either on the face guard or on the casing 5, and is supported at one end by a pair of pins 29 slidable in corresponding holes in a plate 30 to permit expansion. The heater may be suspended or wall mounted by two universal joint brackets 19, the leads to the terminal connectors 6 passing through axial bores in the bolts 21 which pivotally secure discs 20 to the casing, to which discs the bracket members 22 are attached. In a modification Fig. 3 (not shown) in which two separate, axially aligned elements are employed, the inter-connected ends are supported within an additional ceramic ferrule which is externally grooved to receive a wire support.

Abstract: 886,300. Electric selective signalling systems. HUGHES AIRCRAFT CO. Oct. 26, 1960 [Nov. 2, 1959], No. 36817/60. Class 40 (1). A system for measuring both the extent and direction of relative displacement of two members of the type in which a uniformly coded scale on one of the members is sensed by two phase-displaced heads on the other member is characterized in that the true outputs of the two heads are inverted, the true outputs and the inverted outputs are differentiated, and all these eight signals are applied to a gating circuit to provide a train of pulses representing the extent of displacement on one of two leads representing the direction of displacement. As described the outputs MX1, MX2, Figs. 2, 3, of two heads HMX1, HMX2 are inverted to give signals M1, M1 and M2, M2, and these four signals are differentiated to give signals d(M1) &c. These signals are then applied to And gates 13-16 and 19-22 and Or gates 17 and 23 to give a train of pulses from one of two amplifiers 18 and 24 depending upon the direction of the relative displacement of the scale and heads. The arrangements of gates is such that for each graduation of the scale four uniformly spaced pulses are produced.

IPC: A63D15/00
Filed: 1965-09-01
Abstract: In a table game of the kind wherein object balls are propelled over a playing surface by a cue ball towards pockets communicating with a ball storage compartment, the cue ball is the same size as the object balls and has either magnetized or magnetizable material embedded therein, and in the event of its entering a pocket, the cue ball is separated from the object balls by arranging for a magnetic force to be exerted on the balls during the course of their travel towards the storage compartment.  The cue ball is thereby diverted to a separate storage compartment. The said magnetized or magnetizable material embedded in the cue ball preferably comprises metal in the form of either a hollow sphere, segment-shaped pieces, or circular or semi-circular strips, disposed symmetrically about the centre of the ball.  The basic material of the ball is preferably a phenolic resin.

Patent GB-829251-A (GB)
Title: Improvements relating to the manufacture of nitrogen-containing derivatives of benzene carboxylic acids
IPC: C07C233/00
Filed: 1957-12-02
Abstract: Benzene carboxylic acids, in which the carboxylic groups are not attached to adjacent carbon atoms, or their methyl or ethyl esters, are caused to react with ammonia, or a substance yielding ammonia, by heating under elevated pressure, preferably in the absence of dehydration catalysts, and the crude amide formed, which may, if desired, be first separated from the reaction mixture, is subjected to a heat treatment at 350-500 DEG  C. and the products, which include nitriles or nitrile-amides, are isolated. If desired, the two reactions may take place successively in the same reaction vessel and under the same conditions of temperature and pressure.  The starting substance may be benzoic acid, iso- or tere-phthalic acid, or an ester thereof.  Ammonia may be added in liquid form at the start of the treatment, and the reaction with ammonia may be effected at 150-350 DEG  C. in an autoclave.  Instead of ammonia, urea may be used as substance yielding ammonia.  When terephthalic acid is treated, the product of the first stage comprises diamide, monoamide, ammonium salts, and uncoverted acid.  The crude product may be heated at 350-500 DEG  C. under atmospheric pressure.  Preferably ammonia or nitrogen is passed through the reaction vessel.  The reaction products may be continuously distilled from the reaction vessel.  The distillate comprises the dinitrile of terephthalic acid, p-cyanobenzoic acid amide, p-cyano-benzoic acid, amides and ammonium salts of terephthalic acid.  Isolation of the products may be effected by fractional solution or crystallization using selective solvents, e.g. acid constituents may be extracted with bases; iso- and tere-phthalic dinitriles and m- and p-cyanobenzoic acids may be extracted by solution in hot acetone, methylethyl ketone, or ethanol. Separation of the reaction products may also be effected by fractional distillation or sublimation.  In an example, terephthalic acid is heated at 250 DEG  C. under 160 atm. pressure with ammonia. After removal of excess ammonia, the residue is suspended in aqueous ammonia and filtered to obtain the crude diamide.  The dried diamide is heated to 400-420 DEG  C. and is subjected to sublimation and distillation.  The solid obtained in the collecting vessel is sludged with aqueous ammonia, filtered, washed, and dried.  The product is treated with boiling acetonitrile and on evaporation of the solution a mixture of p-cyanobenzoic acid amide and terephthalic dinitrile is obtained. These two components are separated by fractional distillation from methylethyl ketone.  By acidification of the ammonia filtrate and extraction of the precipitate with ether, p-cyanobenzoic acid is obtained.  In another example, terephthalic acid and liquid ammonia are introduced continuously into a pressure tube heated to 350 DEG  to 500 DEG  C. under 160 atm., the reaction time being 6 hours, and the products being continuously removed. Further examples describe similar treatment of isophthalic acid and dialkyl terephthalates.
