Patent GB-973071-A (GB)
Title: Polymeric foam articles
Inventor: TAYLOR STANLEY DOUGLAS
IPC: C08J9/33
Filed: 1960-03-02
Abstract: In a method of making resilient material a liquid bonding agent is deposited on fragments of resilient cellular material, the liquid bonding agent comprising an organic polyisocyanate and a polyether, polyester or polyesteramide polyol having isocyanate-reactive groups in terminal or substantially terminal positions in each polyol molecule or a liquid partially reacted product thereof, the cellular material is compressed in a mould and the bonding agent is allowed to harden into a flexible solid reaction product without the application of heat.  The cellular material may be polyurethane foam or of natural or synthetic rubber. Fragments of cross-sectional dimension greater than 0.3 cm., preferably 0.5 to 1.5 cm. should be used.  Up to 25% by weight of chlorine-containing plasticizer, e.g. trichloroethyl phosphate can be included in the bonding agent to enhance the flame resistance of the products. The molar equivalence of polyisocyanate with respect to polyol may vary from 1.01:1 to 12:1. Suitable polyols are obtained by reacting ethylene oxide with an initial polyol or ethylene diamine. The polyisocyanate is preferably an aromatic or alicyclic diisocyanate.  Triethylamine tri-, ethylene diamine and dibutyl tin dilaurate are suitable catalysts. The polyol and catalyst may be stirred with the fragments and the polyisocyanate is then stirred in. Alternatively a matured syrup of polyol and some of the polyisocyanate is first mixed with the fragments, followed by the rest of the polyisocyanate.  In Examples (1) and (2) fragments of polyether polyurethane foam are stirred with a mixture of an ethylene diamine/propylene oxide/ethylene oxide reaction product and diphenylmethane diisocyanate.  The mixture is put in a mould, and when bonding has occurred at room temperature the body is subjected to humid ageing at 85 DEG C.  The molar equivalence of polyisocyanate to polyol is (1) 9:1 and (2) 5-4:1.

Abstract: 1,121,163. Coin freed apparatus. AUTONUMIS Ltd. 21 Feb., 1966 [23 Feb., 1965], No. 7708/65. Heading G4V. A ticket vending machine, e.g. for temporary insurance, comprises a supply of record material for receiving a personal identifying characteristic and means manually movable after insertion of money to permit such recording and to deliver a ticket identifiable with the particular record. In the Fig., raising of handle 22 to pivot a door 20 on a shaft at its centre of curvature is prevented until the presence of a coin in a rotary pocket (Fig. 3, not shown) frees the door shaft. Strip material 66 extends from a roll, through guides 74, 76, 80 round roller 82, where it is nipped by rolls 86, and past guide 94. On raising the door, rod 72 pays material off the roll, and then hits abutment 106 on lever 98, so that stamp 102 prints the date on the back of the strip. An aperture 78 in guide 74 is revealed, so that the customer may moisten a finger on pad 110 and impress a print on to the front of the strip. This may release an interlock. On pulling down the door, the door shaft rotates shaft 58, so that the roller 82 delivers a length of strip, which may be torn off against edge 96. A spring passing through a dead centre position assists full opening and closing of the door. Pad 110 is replenished from liquid store 112 at each use. An operations counter 114 is also actuated by the door. In another embodiment, the user may set a number of dials to his car registration number, which is then printed on to the ticket before delivery. Where a number of coins is to be inserted, a premature attempt to open the door may return coins already held. In an alternative, the identifying characteristic is given a serial number and the record is retained in the machine, the ticket issued having the same serial number.

Title: Improvements in or relating to d.c. amplifier apparatus
Inventor: WEST FREDERICK LEWIS
IPC: H03F3/40
Filed: 1953-03-20
Abstract: 740,477. Electromagnetic interrupters for D.C. amplification. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 22, 1954 [March 20, 1953], No. 7745/53. Class 38(5) In a D.C amplifying system or a system for amplifying A.C. of very low frequency, the mean voltage at output terminals O1 02 depends on the input voltage at S and also on the size of a feed-back impedance RFB. In the arrangement shown, S is the pick up point or slider of a potentiometer resistance E energized from a D.C. source B. so that it has a positive or negative potential according as its position is above or below the centre point of the resistance, and sends a current one way or the other through the operating coil A of an electromagnetic interrupter having a moving contact CM moving between fixed contacts CF1, CF2. The contact CM is biased to a central position, but when current flows through coil A, say in the direction of the arrow, it will move into engagement with contact CF1, whereupon the supply B will not only deliver current to the output terminal O1 but will also send a reverse current through the resistance RFB and the coil A so that the contact CM is released and moves towards its centre position, breaking the reverse current. The position is now as before and the cycle is repeated indefinitely. A succession of positive impulses is delivered to the output terminal, the mean voltage of which, will depend on the ratio of make to break at the contact CF1 and since the mean current through the coil A must be zero, the presence of the impedance RFB will result in the mean voltage at O1 being a multiple of the voltage at S, unless the latter is so 'high that the contact CF1 is permanently engaged by the contact CM. A similar result is obtained if the slider S is moved downwards instead of upwards, but the current through A is in the opposite direction and the interruption occurs at the contact CF2. In a modification, the interrupter is of the kind in which the moving contact is biased towards its end positions and in consequence vibrates continuously between them when the slider S is in a central position. Opposite voltages are thus applied alternately to the output terminal O1 at the frequency of the interrupter, say 100 cycles per second and the mean output voltage is zero. A capacity CFB is put in shunt with the resistance RFB, so that for the above mentioned frequency the resultant impedance is low. The impedance is, however, high for the D.C. impulses and the resistance RFB serves as before to provide the desired amplification. In a further modification, Fig. 7, amplified signals to one or other of two loads O1 and 03. are supplied according as the current in the coil A is in one direction or the other, and the current in the coil A will depend on the direction of a signal in the coil I.
