Title: Suede-Like Thermoplastic Sheet Material
Inventor: DUERDEN ALAN
IPC: B29C59/02
Filed: 1966-07-25
Abstract: 1,186,519. Embossing. IMPERIAL CHEMICAL INDUSTRIES Ltd. 7 July, 1967 [25 July, 1966], No. 33361/66. Heading B6J. [Also in Division B2] Suede-like material is produced by printing on to a sheet of thermoplastic material one or more areas of a plastisol (e.g. plasticized polyvinyl chloride) of a different colour to that of the sheet, heating the sheet to gel the plastisol, and embossing the sheet using an embossing means having a surface pattern comprising a multiplicity of surface indentations having a depth in excess of 0À002 inch and a surface density in excess of 400 indentations per square inch. The embossing means may be a roller or plate of metal or of a silicone elastomer having a Youngs Modulus in the range from 250-1000 pounds per square inch. The embossing pressure may be 10-1000 pounds per square inch and the temperature (when embossing vinyl polymers and copolymers) from 80-200‹ C. The thermoplastic sheet may be provided with a supporting substrate, e.g. satin drill fabric. The plastisol may be applied with a silk screen or an engraved printing roller. The thermoplastic sheet may be subjected to one or more further printing operations with another differently coloured plastisol before embossing. After printing and before embossing the thermoplastic sheet may be coated with a hard resinous compound, e.g. methyl methacrylate.

Title: Improvements relating to Optical Inspection Devices.
Inventor: WILLIAMSON DAVID THEODORE NELS
IPC: G01D5/38
Filed: 1965-08-04
Abstract: 1,159,033. Digital displacement measurement. MOLINS MACHINE CO. Ltd. 3 Aug., 1966 [4 Aug., 1965], No. 33374/65. Heading G4H. [Also in Division G2] Optical apparatus for measuring the displacement of a scale 1 having markings with light reflecting properties differing from those of the intervening spaces, comprises a plurality of optical fibres each having one end embodied in a composite light transmitting surface 2 confronting the scale 1, the other ends of the fibres being formed into at least two groups 4, 15 each of which provides a further light transmitting surface, the apparatus also including a source of illumination confronting one of said further surfaces and a photo-electric cell 111. . . confronting each of the remaining further surfaces. As the scale 1 is moved past the composite surface 2 the dark markings, reflecting less light than the spaces, cause fluctuations in the light received by each photo-cell. The distance moved by the scale 1 can therefore be determined by counting the pulses emitted by each photo-cell. When a plurality of photo-cells is used as in Fig. 1, the associated groups of fibres 15, 25, 35, 45 each end together with fibres 4 from the source of illumination in different zones of the surface 2, the surface 2 having a width corresponding to that of a dark or light band of the scale 1 and said zones of the surface being arranged along the length of said band. The surface 2 is orientated with respect to the scale bands in such a way that if the first zone containing fibres 15 is aligned with a dark band, the second, third and fourth zones containing fibres 25, 35, 45 respectively will be aligned with a margin between this dark band and an adjacent light band, with the light band, and with a margin between this light band and the next dark band. Movement of the scale 1 will then cause the photo-cells to emit pulses which are out of phase by 0, 90, 180, 270 degrees. Such an arrangement also permits the direction of movement of the scale to be determined. The pairs of photo-cells 111, 311, and 211, 411, are connected in series opposition and in order to increase the output, the surface 2 may be in the form of two or more identical portions facing corresponding parts of scale 1 i.e. if one portion faces a reflecting band on scale 1 so do all the other portions.

Abstract: 656,315. Gas-generating charges. HUTCHISON, A. C., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Dec. 29, 1948, No. 33379. [Class 9 (ii)] Gas generating units comprise in association nitroguanidine and/or guanidine nitrate, at least one non-explosive inorganic reagent, which in sufficient amount is able to effect the self-sustained decomposition of nitroguanidine and/or guanidine nitrate when locally heated producing gases which contain condensable organic compounds, e.g. molybdic acid, ceric oxide, vanadium pentoxide, and selenium dioxide, and a heatresisting filamentary material of high specific surface, such as asbestos, or iron, steel, or platinum fine wire gauze, say not less than 0.25 per cent of the weight of the composition if included therein. The filamentary material is positioned in immediate proximity to the burning surface so that the gases formed pass thereover or therethrough, and if external to the surface the heatresisting material may include the inorganic reagent. The amount of inorganic reagent with guanidine nitrate may be reduced by the inclusion of a non-explosive organic reagent such as tartaric maleic, or fumaric acids, or glucose. The compositions may include reagents which increase the temperature of the evolved gases, e.g. ammonium nitrate or perchlorate, and may be in powder granular or compact form. Specifications 430,258, 627,724 and 644,073 are referred to. The Provisional Specification describes the non-explosive organic reagents as alternative to the non-explosive inorganic reagents.

Title: Apparatus for automatically discharging the centrifuge drum of a continuously operating high speed centrifuge
IPC: B04B1/14
Filed: 1929-11-05
Abstract: 337,970. Egg, K. Nov. 5, 1929. Density separators; driving, discharging. - The drum of a continuously working high speed centrifuge is provided with light metal slides which seal openings in the drum by the centrifugal effect of their own mass, and are drawn inwardly towards the axis by an automatic control arrangement, to unseal the openings for discharge of sludge. The upper and lower parts 62, 63 of the drum are secured together by screws 64, Fig. 1, thus leaving discharge apertures 59 round the circumference. The slides 58 have resilient packing at their outer ends, and normally close the apertures 59. The inner end of each slide 58 is engaged by one end of a pivoted lever 57, the other end of which engages a collar 56 which can be lowered by the rod 41 to force the slides inwards. The drum is driven by a motor 1 through a belt and worm gearing 7, the worm wheel being fixed on an auxiliary shaft 6 driven by the pulley 3 through a friction coupling 4, Fig. 3. A worm wheel 10 loose on the control shaft 15 is rotated by a worm 8 on the shaft 6, and a, series of five cams 12 of unequal heights is keyed on the hub 11 of the wheel 10 to rotate it while axial movement is allowed. The cam 14 for controlling the feed valve 49, Fig. 1, and the cam 38, Fig. 3, for operating the discharge slides 58 are secured to the shaft 15. In operation the centrifuge is brought up to full speed and the valve 47 opened. The liquid enters through the circular valve 49, the socket 50, and the radial passages 52 into the drum. The clarified liquid leaves the drum by the opening 53 and the foreign bodies are deposited on the drum. The operation of the machine continues for a time determined by the engagement of the lever 27, Fig. 2, with one of the cams 12; the pawl 31 causes the ratchet wheel 18 to be moved forward to the extent of one, two, three, four or five teeth according to the cam selected. The detent 20 on the wheel 18 permits the pawl 26 to operate and the shaft 15 is rotated. The cam 14 operates the lever 33 and rod 34 to close the valve 49 thereby stopping the supply of liquid. The cam 38 actuates the lever 40 which depresses the rod 41 and so draws the slides 58 inwards to free the apertures 59 for the discharge of sludge into the passage 61 from which it can be removed by a conveyer. When the discharge action is completed, the spring 42 raises the rod 41 to move the slides 58 outwards, the movement being aided by centrifugal action, and the cam 14 then causes the valve 49 to be opened for the re-admission of the liquid so that the operations can be repeated.

Title: Improvements in trigger and counter circuits
Inventor: PARR WILLIAM GEOFFREY
IPC: H03K3/16
Filed: 1953-12-04
Abstract: 772,660. Electronic counting apparatus. PYE, Ltd. Feb. 25, 1955 [Dec. 4, 1953], No. 33790/53. Class 106 (1). [Also in Group XL (c)] An inductance-capacity oscillator normally biased to non-conducting conditions is keyed on and off by applied pulses. A series, e.g. 20, of such oscillators V2-V5 may be connected as a ring counter only one of which becomes oscillatory and biases by cathode current the other valves to cut-off. When a pulse is applied through a cathode follower valve V6 to all the commonly connected cathodes of the valves the conducting and oscillatory valve is switched off so that a positive going pulse is applied from its anode circuit to the grid of the succeeding valve to render it in turn operative so that the preceding oscillatory valve remains non-conducting after the cessation of the pulse. A small bias derived from H.T. through a resistor RS may be arranged to render one particular valve V5 oscillatory when initially the counter is switched on. Further, a starting resistor RS, through a rotary switch, may be applied to any one of the trigger valves so that the count may be varied. Twenty oscillators may be employed. To prevent interaction, alternate oscillators may be arranged to have slightly different frequencies by adjustable iron duct cores in the oscillator coils.
