Title: Improvements relating to packeting machines for cigarettes and the like
IPC: B65B19/32
Filed: 1936-08-01
Abstract: 479,068. Packeting-machines. HORGAN, G. D., and INDUSTRIAL MACHINERY CO., Ltd. Aug. 1, 1936, No. 21375. [Class 94 (i)] Relates to machines for packeting cigarettes and like articles having detecting means for determining whether a batch is deficient and for setting means for subsequently ejecting the faulty packet. The detecting means comprise a number of fingers 10 arranged in pairs and pivoted on a rod 11, and formed as bell-crank levers each having a horizontally extending arm 10a to engage the upper row of cigarettes in the batch, and a vertical arm 10b carrying a contact pin 12 normally urged by a spring to engage a contact pin 13 on an insulated bar 14. A rock-shaft 20 carries arms 21 with a transverse bar 22 between them, and is actuated before the cigarettes arrive at the detecting position to engage the arms 10b and to raise the arms 10a out of the path of the cigarettes. After the arrival of the cigarettes, the bar 22 is returned, and the absence of a cigarette is detected by the downward movement of the arm 10a into the space, allowing contact between the pins 12, 13. All the arms are raised before the cigarettes are moved away. The arms 10a are arranged in pairs, one for each cigarette, as shown in Fig. 3, so as to detection when cigarettes are only partly displaced. The edges 10c of each pair are shaped to correspond with the curvature of the cigarettes. The bar 14 and mountings are suitably insulated to provide a circuit which, on being closed by any of the contacts 12, 13, energizes a solenoid to cause the subsequent ejection of the faulty packet. The actuation of the rock-shaft 20 may be by cam, electrical or pneumatic means. Immediately preceding the detector device, a flap 26 is pivoted on a mounting 27 to move the cigarettes into endwise coincidence.

Abstract: 1,216,789. Reclaiming foamed thermoplastic selvage. T. W. WINSTEAD. 28 April, 1969, No. 21587/69. Heading B5A In a method where articles 5 are moulded from a foamed thermoplastic web 2, e.g. a foamed polystyrene web, the selvage 4a resulting from the cutting out of the articles by means of cutting roller 6 is densified and then passed to a granulator 11. As shown, the extrudate is passed immediately to moulding apparatus 3, which forms articles 5 by a vacuum or blowforming process, and the selvage is densified between rollers 7 and 9 or rollers 10. In mixer 13, virgin extrusion pellets are added to the granulate and the mixture is passed to extruder 1, the granulate forming 25-50% or more by weight of the mixture. Preferably the temperature of the selvage is reduced to below the boiling point of the blowing agent used, prior to densification. The forming of web 2 and the production of articles 5 may form a two-stage process. The invention may be applied to the single-stage article-forming process described in Specification 1,159,562.
Patent GB-637166-A (GB)
Title: Improvements relating to the manufacture of sintered hard alloys
IPC: C22C1/05
Filed: 1946-07-19
Abstract: A process for the manufacture of sintered hard alloys comprises mixing in the form of fine powders a reducible compound of a refractory metal, a reducible compound of a more fusible auxiliary metal in such proportion as not to exceed 20 per cent by weight of auxiliary metal in the final sintered hard alloy, and a reducible compound of chromium or of vanadium or of each of these metals, reducing the mixture in a carburizing atmosphere, e.g. town gas, at a temperature, e.g. not exceeding 900 DEG C., and for a period, e.g. not exceeding two hours, insufficient to reduce the chromium and/or vanadium compound(s) to the metallic state, determining the carbon content of the reduced mixture and adding thereto the calculated complement of finely powdered carbon required for carburization of the refactory metal and of the chromium and/or vanadium, firing the resultant mixture at carburizing temperature, and finally sintering the carburized product.  Prior to sintering, the carburized product may be intimately mixed with one or more separately prepared finely powdered refractory metal carbides, e.g. a cubic double carbide of titanium and tungsten having the formula Ti3WC4.  The reducible starting mixture may consist of tungsten, cobalt, chromium and vanadium. The said mixture may incorporate reducible compounds of two or more auxiliary metals which form an auxiliary metal alloy in the reduced mixture, in such proportions of the auxiliary metal compounds as not to exceed 20 per cent by weight of auxiliary metal alloy in the final sintered hard alloy.  Preferably, the final sintered hard alloy formed has a total content of chromium and vanadium not exceeding 5 per cent by weight, e.g. 2 to 3 per cent, a further preference being a ratio by weight of chromium to vanadium of between 0.5 : 1 and 1.5 : 1, and a total content of chromium and vanadium of 1.5 per cent.  Specifications 516,227 and 614,053 are referred to.

A pressure control valve comprises a valve member movable toward and away from a seat 21 between an inlet 15 and outlet 27, and having a piston 17 which is subject to the pressure in an inlet chamber 16 tending to close the valve. The inlet chamber communicates with the upstream side of the seat through an adjustable restrictor 18d, and the member is biased to open position by a spring 22. The valve will open on a predetermined fall in the inlet pressure. In a modification the restrictor is provided with a hand wheel (49) and comprises a cylindrical plug valve (48), Fig. 6 (not shown). Brake system.-The device is applied to the brake system of a train used in underground mining. The train may be of monorail suspension type, a brake vehicle of which carries brake shoes 30, 31 applied to the rail 28 by spring 40, 41 acting on hydraulic pistons 36, 37 which are normally pressurized by a pump 45 to hold the brakes off. The brakes may be applied by opening a release valve 47 either manually or on overspeed of the train. The present valve is installed at 13 and also acts as a release valve to apply the brakes fully and prevent drag of the shoes in the event that the pressure falls below a predetermined value. An alternative brake car running or horizontal opposed channel rails (4) Figs. 1 and 2 (not shown), has similar brakes with shoes (9, 10) operating above and below the top flanges of the rails. The car includes guide wheels 5 running between the channels.
