Title: Improvements in and relating to reversible counting apparatus
Inventor: ABBINK-SPAINK PETER FRANCIS
IPC: H03K29/00
Filed: 1958-07-03
Abstract: 937,981. Electronic counting apparatus. ENGLISH ELECTRIC CO. Ltd. Sept. 22, 1959 [July 3, 1958], No. 21331/58. Class 106 (1). A reversible counter comprises a number of multi-cathode glow discharge tubes which, as shown, represent decimal denominations, each tube having twelve cathodes of which one (K1 is by-passed when counting up, and another (K10) is by-passed when counting down, output signals from these cathodes being utilized to effect borrow from or carry into the tube of next higher order. On counting up by phased signals applied to the guide electrodes G1, G2 of the lowest-order tube V1, the discharge is stepped from K0 to K1 K2 . . . and K9, and then to K10; this causes V2 to conduct providing the necessary phased pulses for G1 and then G2 of V2 and also lowering the potential of K0 sufficiently to make the discharge jump immediately to K0 without investing K11. On counting down the discharge is stepped from K0 to K11, which causes V3 to conduct and pulses G2 and then G1 to reduce the count in V4 and also pulses K9 to transfer the discharge to there without investing K10. Counting in the binary scale may be effected by use of four cathodes only. The phased stepping signals applied to G1 and G2 of V1 are, in the embodiment shown, derived from a selsyn on a shaft, the revolutions of which are to be counted; this arrangement is claimed in divisional Specification 937,982.

Title: Improvements in the manufacture of a cement suitable for linoleum and the like
IPC: D06N3/10
Filed: 1926-08-30
Abstract: 274,300. Craven, A. B., Bedford, C. S., and Yorkshire Dyeware &. Chemical Co., Ltd. Aug. 30, 1926. Utilizing waste rubber; fibrous plastic compositions.-A cement suitable for the manufacture of linoleum &c. is made by the incorporation of resinous bodies in vulcanized rubber at such a temperature and for such a time that a change takes place in the rubber, and a completely homogeneous mass results. The resinous substances specified include colophony, Venice turpentine, gum elemi, and the resin obtained by blowing rosin oil, and they may be added in proportions of 20-60 per cent of the rubber with or without softeners such as sharp oil, dead oils, linseed oil, castor oil, olein, tricresylphosphate. Volatile solvents such as xylene, turpentine, paraffin, benzene, toluene may be employed to assist the absorption of the resin by the rubber. Several examples are given of which the following are typical:-(a) Old inner tubes are milled on hot rolls with 30 per cent of rosin, until a test portion shows no specks of rigid rubber. The temperture of the rolls may reach 140‹, but must be sufficient to soften the rubber. An adhesive cement results, which can be blended with cork, wood, pigments, &c., similarly to linseed oil linoleum cement. (b) 100 lbs inner tubes, 50 lbs xylene, and 30 lbs of rosin are rotated in a closed drum for a few hours until the rosin is absorbed in the rubber. The mass is placed in a masticator, and masticated, at first cold, and later at a temperature of 110-130‹ C. Vacuum is applied to the apparatus to remove the xylene. Some or all of the xylene may be replaced by a non-volatile softener such as sharp oil, which remains in the cement. Specification 14150/89 is referred to.

Abstract: 979,303. Granulating. GES. FUR TEERVERWERTUNG m.b.H. June 14, 1961 [April 28, 1961], No. 21535/61. Heading B5A. Granulation of meltable substances, e.g. pitch, natural and synthetic resins, and thermoplastic materials, is effected by passing a stream of the melted material through a coolant whose temperature is above the melting point of the material at the point of entry, progressively cooling the material to solidify it and applying oscillations to the stream before solidification to break it into drops. The oscillations may be effected using an oscillation generator 20, or the feed device may be rythmically shaken or subjected to a beating action, or pressure fluctuations may be produced at regular intervals in the stream. As shown, molten material is fed through a pipe 21 to a nozzle chamber 12 closing the upper end of a coolant chamber 11 and furnished with nozzles 25 which direct streams of material through a coolant introduced by a pump through pipe 24 and discharged through pipe 26, the coolant adjacent the nozzles being preheated by a temporary operating heating coil 22. The granules collect in cone 13 and are discharged periodically by operation of valves 14, 16 through a coolant filled lock chamber 15 to a conveyer 17, the chamber 15 being fed with coolant through pipe 18 and vented through pipe 19. The temperature of the granules in the cone 13 depends on that of the coolant entering through the pipe 24, normally higher than room temperature. Evaporation of the coolant is avoided by working under superatmospheric pressure and this pressure can be chosen so that a cushion of vapour is formed below the nozzles 25 and the coolant extracted through the pipe 26 in vapour form. Agents may be added to the coolant to lower the boundary surface tension. The material and coolant may either flow in the same or opposite directions and either vertically upwards or downwards. Specification 282,994 is referred to.
