Title: Improvements in internal combustion turbines and compressors therefor
IPC: F01C1/00
Filed: 1920-10-20
Abstract: 174,689. Bunker, W. H. Oct. 20,1920. Working-fluid supply.-In an internalcombustion turbine, the rotor 14 is provided with combustion chambers 40 which discharge the exploded gases through inclined passages 61, 62, Fig. 4, against serrated surfaces 63, 64 on the casing end plates 4, 5. The gases exhaust through ports 80, Fig. 1, and a supply of scavenging air is delivered to the combustion chambers through ports 79. The compressed charge is supplied through a pipe 69 and passages in the stationary boss 6 fitted with governor-controlled valves having diamond-shaped orifices, which lead to ducts registering with radial ducts 23 in the rotor spokes. Each duct 23 is fitted at its inner end with a non-return valve, and communicates at its outer end by means of a camoperated slide valve 49, Fig. 5, with a combustion chamber 40, where, after the valve 49 has sealed the chamber, ignition is effected by the point 47 of the stator plug 42 contacting with the rotor spark point 44. A device for compressing the gas and feeding it to the combustion chamber at constant pressure is shown in Fig. 11, and comprises two cylinders 81, 82 fitted with reciprocating pistons 83, 84. The piston 83, which is driven by gearing from the turbine shaft, draws in gas past a check valve 106, and compresses it through a valved pipe 107 into the right-hand space of the cylinder 82, which delivers to the turbine through a valved pipe 109. Under pressure of the compressed gas, the piston 84 is moved to the left, and is adapted at the completion of its travel to trip a device which cuts out the gas supply to the right-hand space of the compressor, and causes the left-hand space thereof to compress air through a valved pipe 209 into the left-hand space of the cylinder 82, thereby producing a pressure on the piston 84 and on the gas at the opposite side, the degree of which is controlled by a valve 216. As the piston 84 moves to the right it actuates automatic resetting- means for the trip device. The pipe 203 communicates with the orifices 79 for scavenging the combustion chambers.

Title: Improvements in or relating to method of manufacturing articles from foam rubber, and articles manufactured by this method
Filed: 1952-11-25
Abstract: A former is dipped into a mass of heat-gellable rubber latex foam and retracted from the mass with a layer of foam adhering thereto; the layer is immediately exposed to heat at a temperature at least equal to the gelling temperature of the foam and under conditions in which the layer is substantially prevented from drying, whereby it is gelled on the former and dripping is prevented.  The operation is repeated until the desired thickness of gelled foamed rubber has been obtained; the layer thus obtained is vulcanized, and is removed from the former.  The exposure to heat may be effected by a heated atmosphere and/or high frequency dielectric heating.  The heated atmosphere may comprise air, gas, steam, vapours or mixtures thereof; it may comprise one or more acid vapours such as formic acid or acetic acid.  Drying of the foam layer may be substantially prevented by using an atmosphere comprising saturated steam and/or by exposing the layer to heat for not substantially more than the gelling time, i.e. 10-30 seconds.  The former may be hot or cold.  Footwear, socks, stockings, gloves and glove linings may be made.

Title: Improvements in or relating to winding frames for textile threads
IPC: B65H54/52
Filed: 1929-10-02
Abstract: 338,291. Stubbs, J. H., and Stubbs, Ltd., J. Oct. 2, 1929. Winding-machines; stop-motions.-In a yarnwinding machine wherein the bobbins are frictionally driven, each bobbin is mounted in a pivoted cradle and is caused to roll off the driving discs on to stationary braking surfaces when the yarn tension becomes excessive. The bobbin 7 is held in a cradle 8 pivoted at 10 to the short arm of a bell-crank lever 11. This lever is pivoted at 12, carries a counterweight 15 on its short arm 14, and a guide pulley 17 and adjustable weight 23 on its long arm. The bobbin is driven from a pair of friction discs 3 by means of discs 5 which are in driving engagement with the bobbin. When the tension in the yarn becomes excessive, the guide pulley 17 is depressed and the bellcrank lever rotated, the bobbin 7 rolls forward on to a stationary member 18, the various parts then being in the positions indicated in dotted lines. The forward motion of the bobbin is assisted by the pull of the yarn, and by the direction of rotation of the driving discs 3. The cradle 8 can be swung about its pivot 10 into a vertical position for bobbin changing.

Title: Improvements in high speed reduction gearing
IPC: F16H57/028
Filed: 1921-11-09
Abstract: 171,392. Clapham, C. F. Nov. 9, 1920, [Convention date]. Toothed gearing.-To eliminate errors of alignment between the pinion and gear wheel of high speed reduction gearing arising from wear of the bearings or from other causes, and to obtain even distribution of load over the whole faces of the teeth, the pinion is formed in two sections with helical teeth of opposite hand and so mounted as to have independent angular movement in a plane tangential to the wheel, and to have longitudinal movement of the sections as a whole. In the form shown, a wheel with sets of helical teeth 21, 22 of opposite hand and mounted on a propeller shaft 3 is driven by pinion sleeve sections 5, 6 mounted on a flexible shaft 4 driven by a turbine. The bearings 9, 10 of the pinion sections are mounted in frames rocking on surfaces on the main housing, and retained in position by centrally disposed bolts 25, the amount of rocking being controlled by elastic side bolts 24. The longitudinal movement of the sections 56 as a whole is permitted by a sliding coupling between the shaft 4 and the motor. In the Specification as open to inspection under Sect. 91 (3) (a), the method of mounting to correct alignment is stated to be applicable to reduction gearing having a pinion in which the sections 5, 6 are integral. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 149,328.

Resin-bonded reinforcing materials, e.g. laminates in continuous lengths, are produced by passing superimposed continuous lengths of resin-impregnated or coated material e.g. glass fibres in mat or fabric, textiles and paper through a bath of liquid metal or metal alloy or mixtures thereof having a melting point of below 150 C. and being maintained at the temperature required to effect the desired degree of cure of the resin during passage through the bath. The material may be impregnated or coated by passing it through a bath of resin or resin solution or by a roller coating or spray coating and is then passed between rollers or guide vanes for the removal of excess resin and to preform it into a suitable laminate which as shown in Fig. 1 is then passed over a roller and enters the liquid metal bath at a point above the liquid level and is directed downwards to a depth to obtain the desired pressure when it may be turned to continue along an inclined rectilinear plane of such a gradient that it emerges above the level of the liquid metal, the speed of passage being so regulated to impart to the resinous binder the required degree of cure, or as shown in Fig. 2 the material is turned at its lowest point of immersion to run for some length, i.e. between the points A and B parallel to the surface of the liquid metal before turned for its upward traverse, or as shown in Figs. 3 and 4 guided by a shaped top platen.
