Title: A process for the production of hard polyurethane plastics materials
IPC: C08G18/67
Filed: 1963-03-29
Abstract: Polyurethanes are produced by (1) reacting an organic polyisocyanate with a mixture of an organic polyhydroxyl compound of M.W. above 600 and a polyhydric alcohol having a M.W. below 500 to prepare a prepolymer, the amount of polyisocyanate being such that 900% to 4000% of polyisocyanate is present (calculated on the compound of M.W. above 600) and the amount of the polyhydric alcohol of M.W. below 500 being such that an excess of at least 150% of the organic polyisocyanate remains after reaction with all the hydroxyl groups of the two compounds and (ii) reacting the prepolymer in a second stage with additional polyhydric alcohol to bring about cross-linking. Compounds of M.W. above 600 may be: polyesters, polyalkylene ethers, polyester amides, polyhydric polythioethers, polycarbonates and polyacetals, preferably of M.W. 1000-3000 and OH number 30-80 and acid number below 2; suitable compounds are specified.  The usual polyisocyanates are mentioned including diphenyl sulphone 441 diisocyanate, p,p1,p11-triphenyl methane triisocyanate and furfurylidene diisocyanate.  Also mentioned are dimeric toluylene 2,4-diisocyanate, partially a perhydrogenated diphenylmethane 4,41-diisocyanate and halogenated and/or alkyl substituted, carbodiimide and/or siloxane group containing isocyanates.  The polyhydric alcohol of M.W. below 500 used in the first stage may be a trihydric alcohol, e.g. trimethylol propane, and that in the second step a dihydric alcohol, e.g. butane diol.  The reaction may be performed at 80-150 DEG  C. and in the presence of an ethylenically unsaturated monomer, e.g. styrene,acrylic and methacrylic acid esters and amides and acrylonitrile.  The vinyl compound is added in amount so that the ratio of polyurethane and vinyl monomer is between 1000: 1 and 1: 10.  Polymerization catalysts may be ditertiary butyl peroxide, cumene tertiary butyl peroxide and azo diisobutyric acid dinitrile.  In typical examples:  (1) an adipic acid-ethylene glycol polyester was reacted with trimethylolpropane and tolylene diisocyanate, and cross-linked with butane 1,4-diol; (II) Tolylene diisocyanate was reacted with butane 1,4-diol and an adipic acid-ethylene glycol polyester, styrene and additional butane diol were added and the melt cast into moulds.

Title: Marking device
IPC: B41F17/16
Filed: 1961-04-10
Abstract: 931,876. Printing machines. ADOLPH GOTTSCHO Inc. April 10, 1961 [Aug. 8, 1960], No. 12786/61. Class 100 (2). A marking device comprises guide rails for advancing a container in a pre-determined path of travel, a rotary imprinter swingable into contact with the container and an actuating star-wheel drivingly interconnected with the imprinter and extending into said path. The coding device 10 in Fig. 1 is fixed to a rail 14 of a slat-chain conveyer 15 by a support frame 11 and comprises a bridge 18 carrying guide rails 19, 20 for advancing containers 25 which rotate the actuating star-wheel 24 fixedly mounted on a shaft 29 (Fig. 3) which is floatingly mounted in a block 27 by a spring 32 pressing against a knob 33. The lower end of the shaft 29 is provided with a bevel-gear 38 meshing with a bevel gear 39 to drivingly interconnect an imprinter 23, of rubber or a synthetic plastic material, with the star-wheel so as to rotate with it in synchronism and at the same speed as the container. The imprinter is of triangular shape having concave interconnecting sides so that each leg 43 carrying a standard type 44 can be swung into contact with concave or curved bottoms of the containers. An inking wheel 45 made of any ink absorbent material is rotatably carried on spindle 46 and so positioned that rotation of the imprinter will cause the type 44 to brush against the ink wheel (Fig. 4). The tension of the spring 32 allows the imprinter to be moved downwardly to accommodate irregular container bottoms. The printing height can readily be adjusted by a screw 34, which comes into abutment with a stop 31 fixed to the shaft 29 and which is vertically slidable in a slot 30 of the block 27. This arrangement also allows the imprinter to be swung out of line by depressing and turning the knob 33 without stopping the flow of containers. To accommodate containers of smaller size auxiliary guide rails 51, 52 (Fig. 5, not shown) can be attached to guide rails 19 and 20 and a cooperating auxiliary star-wheel 54 (Fig. 8, not shown) superposed on the star-wheel 24.

Title: Improvements in and relating to dobbies
IPC: D03C1/14
Filed: 1936-05-06
Abstract: 464,722. Loom dobbies. STAUBLI, H., STAUBLI, jun., H., STAUBLI, R., and STAUBLI, H. H., (trading as STAUBLI & CO., GEB.). May 6, 1936, No. 12823. Convention date, June 4, 1935. Addition to 447,700. [Class 142 (i)] In a dobby with mechanically-driven broken pick finding devices as described in the parent Specification, a control lever 15 is movable from a central neutral position, wherein a shaft 1 driven from the loom drives the dobby camshaft, from which the pattern cylinder as well as the lifting knives can be driven, to two extreme positions wherein the drive from the loom shaft is interrupted and the dobby shaft is driven from one or the other of two wheels 7, 11, continuously rotated, but in opposite directions, for example, by spur-and-chain gearing respectively from a shaft 9 driven by a motor. In one form, when the lever 15 is central, a claw 31 on a clutch 27 driven by a claw 29 on a bush 28 fast on the shaft 1 drives a wheel 5, which is fast to a sleeve 6 and is geared to a bevel wheel 4 on the dobby shaft, but when the lever is moved to the right or left, a pivot 21 is turned by lever mechanism 19, 20 and a lever 26 disengages the clutch 27 from the wheel 5, against the action of a spring, thus interrupting the drive from the loom shaft. At the same time, the lever 15 moves a coupler 14 keyed to the sleeve 6 so that teeth thereon engage one or the other of the continuously rotating wheels 7, 11, the dobby shaft being driven thereby either forwardly or backwardly. In another form, a double clutch meshing with a long pinion fast to the dobby shaft, is slidable on the shaft 1 from a central position wherein it is driven by a key thereon to extreme positions, wherein it is out of the range of this key but is driven by one or the other of two wheels rotating continuously but in opposite directions loosely on the shaft 1. In another form described, the control lever carries two toothed wheels which are continuously driven in opposite directions.

IPC: H04L25/04
Filed: 1930-04-25
Abstract: 353,515. Code telegraphy. STANDARD TELEPHONES & CABLES, Ltd., SANDEMAN, E. K., and CURRAH, L. E. Columbia House, Aldwych, London. April 25, 1930, No. 12834. [Class 40 (iii).] Dots lost in transmission are reinserted at the receiving station by thermionic or other non- mechanical apparatus. Signals received from the cable C, Fig. 1, are restored as to phase and amplitude at A and passed through the low-pass filter LP.F, squaring device SD1, and separating amplifier SA to the receiver R. The cable also conveys synchronizing signals in the form of a carrier which has been modulated at a submultiple of the dot frequency ; these pass through the high-pass filter HPF, demodulator DM, and phase adjuster PS, to the frequency-multiplier or dot-maker FM, which produces impulses recurring regularly at the dot frequency. These impulses are squared at SD2 and applied via the push-pull amplifier PPA to the receiver R, so as to replace the lost dots. When, however, a positive or negative line-condition endures for more than one dot period, valve 3 or valve 4, as the case may be, takes current and so, by the voltage drop in resistance 6, applies a paralysing voltage to the amplifier PPA ; valves 3, 4 thus constitute a paralysing detector PD. In a modification the signals going out from LPF are applied across resistance 27 of the squaring device shown in Fig. 4, while the dots from the frequencymultiplier FM are applied to resistance 17, the parts SD1, SD2, PD, PPA, SA, being dispensed with. The system shown in Fig. 4 is unstable except when one or other of the valves 1, 2 is blocked while the other is taking full current. In the absence of line signals the regular dot currents applied to resistance 17 send the system alternately into its two stable states, and a succession of dots is recorded. When line signals are applied to resistance 27, however, they overpower the signals from the dot-maker. The squaring devices may be as described in Specification 352,401.

Abstract: 561,905. Discharge apparatus. WESTERN ELECTRIC CO., Inc. Sept. 21, 1942, No. 13295. Convention date, Oct. 29, 1941. [Class 39 (i)] A composite electrode structure comprises one or more groups of four annular electrode elements A, B, C, D, Fig. 1, mounted one above the other so as to contain a substantially cylindrical discharge space, the successive elements being so constructed and arranged that when an alternating potential is applied between one pair of elements in each group and a similar alternating potential differing in phase by 90 degrees is applied between the other pair of elements, the successive elements each provide distinctive potential contributions, for building up an electric field in the discharge space, which vary progressively at successive points around the boundary of the discharge space in such a manner that a radial field rotating about the longitudinal axis is produced. As shown in Fig. 1, the elements are portions of cylinder 14 varying in width according to a sinusoidal law. Electrons from cathode 11 formed into the beam by a cylinder 12 are deflected by the composite electrode strucfure and impinge successively upon output anodes 13. In another form, the composite electrode 14, Fig. 4, is placed outside the output anodes 19 and the beam T from cathode 18 rotates round the cathode impinging successively on the anodes. In a modification, the elements are formed' by eccentrically arranged rings A<2>, B<2>, C2, D<2>, Fig. 5, the potential contribution of a single ring being varied around its circumference by reason of the shield action of the other rings. The rings may be replaced by discs having eccentrically arranged apertures piled one upon the other with insulation between, each disc being provided with a different pattern of large and small holes through which pass rods making contact with the small holes, but insulated by bushings arranged in the large holes. In this way similar elements are connected together.
