Title: Plastic Laminate
IPC: C08F8/00
Filed: 1967-06-30
Abstract: 1,170,630. Laminates. PERSTORP A.B. 30 June, 1967 [5 July, 1966], No. 30364/67. Heading B5N. [Also in Division C3] A plastic laminate has at least one surface layer which comprises a resin produced by reacting an allyl ether of a polyhydric alcohol, said ether containing at least one free hydroxyl group per molecule, with a vinyl or vinylidene compound to yield a polymer containing free hydroxyl groups which are essentially derived from the allyl ether, and cross-linking the polymer with at least one cross-linking agent. When the surface layer of the laminate consists solely of the said resin without the usual transparent surface sheet, the polymer is preferably produced from a mixture of trimethylolpropane monoallyl ether and methyl methacrylate. Examples are given of the production of laminates from core papers and other papers, employing as the surface layer a melamineimpregnated paper to which has been applied a solution containing a trimethylolpropane monoallyl ether-methyl methacrylate-ethyl acrylate copolymer and hexamethoxymethyl melamine.

Title: Improvements to the magnetic separation of materials
IPC: B03C1/14
Filed: 1933-11-02
Abstract: 423,684. Magnetic separators. WOODALL-DUCKHAM (1920), Ltd., BROOKE, S. A., and TOPLEY, A. F., 136, Victoria Street, London. Nov. 2, 1933, No. 30480. [Class 72] In the magnetic separation of materials, the latter are first classified into two grades, the fine grade passing from a hopper A on to a conveyer B and being fed directly on one side of a drum C rotating about an electromagnet D provided with a gapped part D<1>, and the coarse grade from a hopper A<1> on to a belt B<1> and then directly on to the other side of the drum C. The magnetic particles fall into a receptacle F the inlet of which is adjustable by pivoted plates F', and the non-magnetic particles into receptacles E, E<1>. In a modification, the materials are fed from a hopper H on to an inclined reciprocating screen I, the coarse particles passing along the shoot J<1> on to the drum C, and the fine particles along the shoot J.

Title: Improvements in and connected with offset printing machines
IPC: B41F21/08
Filed: 1933-11-02
Abstract: 426,814. Printing-machines. ALLEN, J. C., 11, Roman Crescent, Roundhay, and THRUSH, F., 177, Street Lane, both in Leeds. Nov. 2, 1933, No. 30498. [Classes 100 (i) and 100 (ii)] A rotary offset printing - machine is constructed of an upper plate cylinder 1, an offset cylinder 17, and an impression cylinder 21 to which the sheets are fed by means of grippers on endless chains 34. The cylinder 17 is mounted in adjustable bearings 19 carried by a sliding box 20, which is acted on by springs 24 tending to trip the cylinder. A lever 27 acts on a plate 25 secured to rods fixed at each side of the box 20 and keeps the cylinder in printing position normally. The lever 27 can be actuated by a toggle link 29 to move the lever 27 to the position shown by dotted lines and thus to permit the spring 24 to trip the cylinder. The toggles 29 are actuated from a cam 36 on the shaft of the impression cylinder, which reciprocates a bar 38 supported on parallel links 38 and fitted with a claw 42<a> capable of engaging a pin 43 on the toggles 29. The engagement of the claw with the pin is controlled by a lever 30 which can be operated by a link 31, and a lever 32 with an actuating handle 30 to raise or lower the bar 38. When the bar is raised the cylinder remains in action, but when it is lowered the cylinder is tripped. The pin 43 is received in a slot 41 when the cylinder 17 is tripped. The cylinder 1 is fitted with damping-rollers 9 adjustably mounted and supplied with moisture by a spray 58 connected to a pump 55 which may be operated from the impression cylinder. Alternatively a hand-pump 55 may be used. The inking rollers 5 are mounted in a frame 12 which may be raised by cams 14 to trip the rollers. The damping and inking rollers are driven by a belt 15 which passes around the plate cylinder. The rollers 5 are supplied from a duct 5 by a messenger roller 4 actuated from a cam 7 on the shaft 8 of the plate cylinder 1. The conveyer 34 can be put out of action, and a web 84 fed from a reel 62 be printed on. When sheets are used they may be fed by a reciprocating bar 49 which is synchronized with the printing-mechanism. The feed grippers are opened and closed relatively to the fixed gripper bars by means of substantially P-shaped levers 45 on the gripper shafts which are formed with adjustable blocks to enable the timing of the grippers to be adjusted. The grippers are opened to receive the sheets by cam-plates 46 engaging rollers 45<a>, and cam plates 44 engage arcuate edges 45b of the levers 45 to maintain the grippers open until the sheet is ready to be gripped, and finally permit closing of the grippers under spring action.

Title: Improved thermionic valve amplifying circuit
Inventor: BOSTON DAVID WHITEHEAD
IPC: H03F1/36
Filed: 1947-11-20
Abstract: 659,067. Valve amplifying circuits. BRITISH ACOUSTIC FILMS, Ltd. Nov. 20, 1947, No. 30778. [Class 40 (vi)] The capacity effect of the screened input to a multistage thermionic amplifier is reduced by connecting the screen to a point in the amplifier where a voltage appears in phase with the input, and the current flowing is greater than that in the first stage. As shown, the input lead W of the first stage V1 of a three-stage amplifier has a screen S, the stray capacity of the lead to earth being shown at C2. The feed-back voltage developed across a resistance R1 in the cathode circuit of V1 together with the voltage across variable resistance R2, connected between the cathode end of the resistance R1 and a resistance R3 in the cathode circuit of the output valve V3 are applied to the screen S, and may be equal to the input voltage or greater than the input voltage in which case attenuation due to the stray capacity C2 may be compensated. A peak in the amplifier response at high frequencies may be obtained by producing a phase change in the amplifier as by condenser C3.

Abstract: 855,949. Textile drafting apparatus. DEUTSCHER SPINNEREIMASCHINENBAU INGOLSTADT NIEDERLASSUNG DER SCHUBERT & SALZER MASCHINENFABRIK A. G. Sept. 26, 1958 [Nov. 20, 1957], No. 30788/58. Classes 120(2) and 120(3). In apparatus for detecting and correcting irregularity in the thickness of sliver undergoing drafting, comprising a detector influencing through a rod-linkage a control means which includes rod-setting elements controlling a transmission or source of power, the linkage being displaceable to give the setting-rods a constant controlamplitude whatever the thickness of the sliver undergoing treatment, the linkage includes an element 5 which is hinged vertically to an arm 4 and which bears against an arcuate arm 7 of an angled lever 7, 70 which displaces the setting-rods by a coupling member 9 mounted on a link 8 fixed to the machine frame and which carries the setting-elements 10, 11, means being provided to shift the element along the arcuate arm and to secure it in position according to the thickness of sliver being drafted. In Fig. 1, the detector comprises rollers 2, 3 connected to the element 5 by a spring-urged link 40. When sliver of thickness D is being drafted, the end 6 of the element assumes a position 61 so that the arm 7 is drawn downwardly by a spring 5<SP>1</SP> for the arms 70, 9 and the setting-members to be deflected to an extent indicated by a pointer 72. The setting-members are then restored to their original positions as indicated by the pointer by moving the arm 5 through a nut 16 on a threaded rotatable shaft 14 to a position 5<SP>11</SP>. In all positions the arms 5, 7 are substantially at right angles, and instead of the nut 16, a sliding- member with a securing-nut may be used to connect them. The positions of the rods as set by irregularity in the sliver may be "read"  by electro-magnetic means.
