Abstract: 1,137,562. Moderating neutrons. UNITED STATES ATOMIC ENERGY COMMISSION. 1 Sept., 1966 [6 Oct., 1965], No. 39179/66. Heading G6P. [Also in Divisions C4 and H5] In obtaining a radiographic image of a sample, a beam of neutrons is generated and passed through the sample to impinge on an adjacent neutron sensitive thermoluminescent material, the material is heated to cause it to luminesce and the light emitted recorded to give a radiographic image of the sample. The recording means may be a photographic plate, or the image may be fed via an orthicon tube into a T.V. display system. The thermoluminescent material used may be lithium aluminate or lithium fluoride, the lithium content of these being 95À6% by weight of Li<SP>6</SP> and 4À4% by weight of Li<SP>7</SP>. The fluoride may be in the form of a plate 1mm. thick which is heated to 210‹ C. to excite the luminescence. The neutron beam used may have an intensity of 3 x 10<SP>7</SP> neutrons/cm<SP>2</SP>/sec, and exposure time at this intensity is 3 hours.

Title: Improvements in and relating to polycarbonates
IPC: C08G64/02
Filed: 1961-11-10
Abstract: Polycarbonates are made by reacting 2,2,4,4-tetramethyl-1,3-cyclobutane diol (or an ester thereof) with a di-ester of carbonic acid. Reaction is effected at 50-350 DEG  C. possibly in the presence of a catalyst, e.g. magnesium, lithium hydroxide, lithium acetate, zinc oxide, lead oxide, manganese dioxide, a titanium ester or an alkyl zinc.  The reaction mixture may also include (a) another dihydric alcohol, which may be aliphatic, cycloaliphatic or aromatic; (b) a dihydric phenol which may be a bisphenol, a dihydroxybenzene, a dihydroxybiphenyl or a dihydroxynaphthalene; (c) a dicarboxylic acid (or an ester or anhydride thereof), which may be saturated or unsaturated aliphatic, cycloaliphatic or aromatic; (d) a hydroxycarboxylic acid which may be aliphatic or aromatic, and in which all three reactants may be reacted simultaneously or the di-ester of carbonic acid may first be reacted with the cyclobutanediol and the resulting bis-(carbonate ester) then reacted with the hydroxy acid. In examples polymers were made by reacting 2,2,4,4 - tetramethyl - 1:3 - cyclobutanediol and diphenyl or dibutyl carbonate, possibly together with bisphenol A, 2,2-(4,41-dihydroxy-3, 31-dimethoxy-diphenyl) propane, 2,2-(4,41-dihydroxy -3,31 - dimethyl - diphenyl) propane or adipic acid.

Title: Improvements in or relating to electric control circuits
IPC: H04B3/04
Filed: 1957-12-30
Abstract: 855,997. Automatic volume control. SVENSKA RELAFABRIKEN A.B. Dec. 30, 1957 [Oct. 31, 1957], No. 40337/57. Class 40 (4). A variable attenuation network comprises shunt non-linear resistances controlled from a bias source having two variable D.C. voltages of opposite sign superimposed thereon. The arrangement is used to condition a two-way amplifier in accordance with the amplitude and directions of speech currents received by it. As shown, terminals a, b and c, d are connected across the inputs to stages of amplifiers amplifying signals travelling in opposite directions. Thus the rectifiers D9, D10 and condensers C13, C14 constitute a shunt across the inputs of one of the stages. Rectifiers D9, D10 are normally partially conducting due to bias over resistors R13, R17. When the input to transformer T1 exceeds the bias, applied over resistors R12, R15, to rectifier D5 the condenser C10 charges with such a polarity as to decrease the D.C. through rectifiers D9, D10, thereby decreasing the shunt effect on the amplifier. Likewise a signal exceeding the bias on D3 charges C11 to increase the D.C. through D9, D10 and thereby increase the shunting effect. The upper controlling network operates in a similar manner. The latter is associated with the amplifier output which provides the input for T2. The lower network is associated with the amplifier whose output provides the input for T1. Thus the gains of the amplifiers in the two directions are arranged that when one rises the other falls, thereby preventing singing.

Title: Method and apparatus for protecting the lateral marginal portions  of sheetlike or ribbon-like material
IPC: B21D51/26
Filed: 1971-09-01
Abstract: 1320591 Binding edges TOYO SEIKAN KAISHA Ltd 1 Sept 1971 [2 Sept 1970] 40826/71 Heading B5K [Also in Division B8] A method for binding edges of sheet-like material comprises attaching adhesive tape to one side of a continuously advancing sheet so that a portion projects beyond one edge of the sheet, then employing a body rotating about an axis extending generally in the direction of advance of the sheet to fold the projecting portion around the edge. In the apparatus shown sheets 1 are conveyed by rollers 21 past induction heating means 7 which heats marginal portion 6 to receive thermoplastic tape 3 which is affixed by rolls 8, 9 to leave a projecting portion 27. A roller 10 prevents accidental folding and a member 11, preferably as shown a stiff bristle brush rotates about an axis roughly parallel to the direction of motion of the sheets to fold portion 27 against the side edge of the sheets. Brush 11 can be used to complete the folding on to the opposite surface of the sheet or this can be done by a press brush 12 or a roller (12b, Fig. 9(d) not shown). The folded tape is held in position by rolls 22, 23 and melt adhered by heater 24. A position regulating device (28, Figs. 2, 3, not shown) ensures that the same width of projecting tape extends from the whole sheet and the axis of rotation of the brush 11 is preferably tilted towards the sheet so that the bristles bite more deeply towards the downstream end; alternatively a frusto-conical brush can be used for the same effect.
