Title: Improvements in or relating to the production of sponge rubber
IPC: C08J9/00
Filed: 1948-07-06
Abstract: Sponge rubber is produced by frothing latex, adding some unfrothed latex and simultaneously or subsequently a thickening agent followed by a delayed coagulent, stirring until homogeneous and vulcanizing, the usual vulcanizing agents being added before stirring.  The frothed and unfrothed latex can be of the same or different composition and the ratio of unfrothed to frothed can vary from 1/5 to 1/1 or even more.  A sulphonated fatty alcohol is added as an aid to frothing.  Specified coagulants, preferably in the unfrothed latex, are sodium silicofluoride or a salt of a divalent metal. Thickening agents are vegetable gums, e.g. carob seed gum or gum tragacanth, tapioca flour or ammonium acrylate.  In a modification, the frothed latex contains the vulcanizing agents except zinc oxide but contains free ammonia, while the unfrothed latex has added thereto a higher fatty or soap acid salt, e.g. potassium oleate, and sufficient zinc carbonate or hydroxide to form a zinc amino complex with the free ammonia, the said complex replacing the coagulent and the thickening agent.  Specification 576,812 is referred to.

Abstract: 1,160,334. Cars continuous forming trains; undercarriages; axles. UNITED AIRCRAFT CORP. 21 April, 1967 [11 May, 1966], No. 18408/67. Heading B7L. Relates to a single axle suspension system between the adjacent ends of two cars of a railway train. As shown in Fig. 1, support arms 8, 10 extend upwardly from, and are pivotally connected, through rubber torsion bushes 12, to longitudinally directed trunnions (not shown) on axle boxes 4 at the ends of the axle 2. The upper ends of the arms 8, 10 support, through plates 27, pneumatic springs 14 which in turn support, through plates 25 and struts 20, the adjacent ends of the two cars (not shown). The plates 25, 27 are supported from the car ends by pairs of lateral links 24, 26. The axle boxes are also connected to the car ends at each side of the train by extensible drag links 6 which together with the preceding described members, are similar to those described in Specification 845,899. The invention is characterized in that the axle boxes are connected by transoms 30, 32 to prevent rotation of the boxes and by pairs of flexible cables 40 connected between the axle boxes and the adjacent car ends, with the interpositioning of rubber bumpers 41. The cables limit downward vertical movement of the axle 2 with respect to the car bodies to prevent disconnection of the suspension in event of a derailment. Normal slack in the cables is takenup by lightweight springs 42. When one or other cable 40 is taut the extension of its longitudinal axis is arranged to pass through the normal longitudinal central vertical plane of the car body, at a height approximating that of the centre of gravity of the car.

Abstract: 659,544. Frequency modulation. SYLVANIA ELECTRIC PRODUCTS, Inc. July 14, 1949, No. 18639. Convention date, July 19, 1948. [Class 40 (v)] A demodulator for received frequencymodulated waves, of the kind known as a ratio detector, is modified by the use of crystal rectifiers instead of diodes, and by connecting the associated resistors across the rectifiers instead of in series therewith. The F.M. input is applied to a tuned circuit L2 across which are connected in series the two rectifiers CR1, CR2, which may comprise germanium crystals, and a large condenser C1. The rectifiers are poled so that they conduct in the same direction round the series circuit. Each crystal is shunted by a resistor R1, R2, the values of which are equal and are large compared with the forward, and low compared with the backward, resistance of the rectifiers. A small condenser C2 connects the two resistors. A coil L3 derives quadrature voltage from the input coil L1 and feeds it to a centre tap on the tuned circuit L2. The demodulated output O is taken across a condenser C3 connected between the free end of the coil L3 and the earthed side of the condenser C1. An A.V.C. voltage may be derived across the condenser C1.

Abstract: 866,831. Photographic copying apparatus. RICORD, J. June 12, 1959 [June 12, 1958], No. 18846/58. Class 98(2) A photographic copying apparatus includes a thin sheet of transparent material such as polyethylene which is automatically interposed between the original and the printing material to prevent sticking when these are pressed against a platen for exposure. Fig. 1 shows a cylindrical platen 2 of transparent material such as "Perspex", which contains a mercury vapour tube 6, and to which are secured by the metal binding strip 10 a transparent polyethylene film 8 and an opaque blind 24. These latter are tensioned by spring rollers 12 and 28 respectively. A roller 22 is spring-urged towards the platen 2 so that the printing material 32 which is placed between the blind 24 and the separating film 8, and the original 34 which is placed between the film 8 and the platen 2, are simultaneously caught and wound on to the platen by rotating the cranked handle 20. Means for feeding in and extracting the original and copy may be added according to the prior art. For the repeated copying of a single original, that end of the transparent film 8 not attached to the platen 2 is left free to wrap itself round the platen, which is continuously or intermittently rotated in the same (anti-clockwise) direction, and the blind which serves to press the printing material against the film is in the form of a continuous belt, the feeding-in means for the printing material being so adjusted as to present each piece of printing material at the correct location with respect to the original. If a material such as polythene, which has a "clinging" characteristic, is used, slip of the original is resisted during rotation.
