Abstract: 1,239,157. Embossing. IMPERIAL CHEMICAL INDUSTRIES Ltd. 20 April, 1970 [29 April, 1969], No. 21813/69. Heading B6S. [Also in Divisions B1-B2] A process for producing an embossed plastics sheet comprises forming a coating of a plastics composition, including a blowing agent, on a support and heating the coating to cause expansion of the coating while maintaining the other surface in contact with a heat sink maintained at a temperature less than the decomposition temperature of the blowing agent and having a discontinuous surface so that the coated support is expanded only in selected areas. The support or the coating may be contacted with the heat sink which may be in the form of a rotating roller provided with a plurality of depressed areas filled with an insulating material such as silicone rubber. The heat sink may also be in the form of a plate, mesh or grid. The plastics composition may be a vinyl chloride polymer. A second layer of plastics composition not including a blowing agent may be applied over the first layer before blowing. Suitable support materials are paper or fabrics.

Abstract: 1,257,084. Transistor monostable circuits. INTERNATIONAL BUSINESS MACHINES CORP. 1 April, 1969 [2 April, 1968], No. 16979/69. Heading H3T.  A monostable circuit comprises a complementary emitter follower T5, T6, a timing circuit C1, R1 in a feedback path to a comparator T2, T3 controlling the emitter follower and a further transistor T receiving the triggering signal. As shown, T5 is normally saturated and the output terminal A is connected to a stable voltage U ref - provided by a transistor T7. A pulse at E causes T5 to be cut off and T6 to be saturated so that the output terminal A falls to earth potential. This fall is transferred through C1 to a comparator T3, T2 to hold T5 and T6 in this state. C1 charges through R1 and a diode provided by T4, until T3 becomes conductive and restores the circuit. T4 is in the same housing as T3 and provides temperature compensation. Resistor R8 may be replaced by a constant-current transistor (Fig. 4, not shown) and a diode may be inserted at 2 to protect T3 against reverse voltage, a similar diode being inserted at 3 to preserve symmetry. The circuit may be used to demodulate frequency shift signals, the triggering being effected at zero crossings and a filter being connected at A through a matching resistor R7.

Abstract: 1,257,854. Pressurized dispensing containers. S. C. JOHNSON & SON Inc. July 1, 1969 [July 16, 1968], No. 33281/69. Heading F1R . A dispenser assembly for a pressurized can, which utilises a small quantity of gaseous propellant immediately after termination of discharge to blow out any residue remaining in a bore 44 of a stem 15, comprises a valve body 16 and a cupshaped housing 30 positioned inside such that two chambers are formed, a first chamber inside the housing 30 and a second chamber between the housing 30 and body 16. The stem 15 and housing 30 are biased towards the position shown in Fig. 2 by springs 47 and 49, with a gasket 50 covering an orifice 25 in the side of the body 16. On depressing the stem 15 so that an opening 46 therein communicates with the first chamber, the product in the dispenser is forced up dip tube 24 by the pressurized gas in the can, and through the first chamber and the opening 46, and is thence forced up bore 44 to be discharged. Depressing stem 15 also presses down via spring 47 the housing 30 sufficiently to uncover the orifice 25 and so the second chamber becomes filled with the pressurized gas. On releasing the stem 15 the springs 47 and 49 push the stem 15 and the housing 30 back into the position in which the opening 46 is in communication with the second chamber so that the pressurized gas expands into the bore 44 clearing the latter of any residue of the product being dispensed.

Abstract: 1,264,943. Nuclear fuel. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 19 April, 1971 [23 March, 1970], No. 14023/70. Heading G6C. A nuclear fuel body is made by coating fission product-retaining nuclear fuel particles with at least two layers of coating material, the outer layer being more readily deformable than the inner layer under pressure, and then pressing the particles so that the outer layer material substantially fills the interstices between the particles. In an example uranium dioxide particles coated with pyrolytic carbon and silicon carbide are further coated with two layers of a mixture of graphite powder and phenolformaldehyde resin, the outer layer having a higher proportion of resin. After heating and applying pressure in a die, the resin is polymerized and carbonized by heating to form a coherent mass of fuel particles dispersed uniformly in a graphite matrix. In other examples (a) the outer coating layer contains stearic acid as a lubricant/plasticizer; (b) the inner layer is polymerized before applying the outer layer; and (c) graphite powders of different particle size or origin are used in the two coating compositions.
