Title: Improvements in and relating to clutches or brakes
IPC: F16D13/20
Filed: 1934-06-05
Abstract: 439,297. Friction clutches. SHEEPBRIDGE COAL & IRON CO., Ltd., and DOWSWELL, N. A., Sheepbridge, Chesterfield. June 5, 1934, No. 16743. [Class 80 (ii)] [See also Group XXXIV] A clutch comprises friction members adapted to be engaged with a clutch drum by toggle links connected to a cross-head sliding in guides and actuated by a toggle link connected to an operating member movable over a shaft axially of the clutch drum. Fig. 2 shows an internal clutch comprising a pair of shoes e pivoted at f to a driver a, keyed to the shaft b. Toggle links g are connected to the shoes and to a crosshead h sliding in guides on the driver a, the cross-head being connected by a toggle link k to a collar m splined to the shaft b. Axial movement of the collar expands the shoes to engage the driven pulley c, d freely mounted on the shaft. Figs. 3, 4 show an external hand clutch in which the cross-head 5 slidable in guides 6 on the loose driven pulley 4 is connected by the toggle link 7 to the axially slidable collar 8 and to toggle links 9 which are connected also to levers 10 on spindles 12 mounted in the pulley 4. The spindles have other levers 13 connected to the ends of a pair of half-bands 15 mounted on the pulley by a pin 16. By sliding the collar 8 the bands are caused to grip the driver 2 keyed to shaft 3.

Title: Improvements in and relating to marine steam turbines
IPC: F01D1/30
Filed: 1920-06-21
Abstract: 169,020. Rodberg, A. M. June 21, 1920. Combined-flow type; reversing; leakage-preventing devices.-In a reversible marine turbine the steam first flows circumferentially round rings of peripheral blades 108 on the rotor 26 and then flows axially through inner rotor blades 107 and stator blades 102. The blades are so shaped that when the direction of flow is reversed, the rotation is reversed. A reversing and distributing valve 61 in the steam chest 37 supplies steam in one or the other direction to the peripheral blades 108, and is provided with conduits for receiving the steam exhausting from one ring of said blades and delivering it to two rings, and so on with progressive expansion, the steam finally exhausting into a chamber 31 from which it is led by a pipe 33 to a secondary chest 32 containing a reversing valve 89 controlling the supply and exhaust for the axial-flow blades 107. The valves 61, 89 are operated by a common gear. To prevent the escape of steam, inclined grooves 110, Fig. 18, are formed in the blade rings 98 and the adjacent stator members.

Title: Improvements in or relating to electric resistance heaters
IPC: F24D13/02
Filed: 1954-06-09
Abstract: 739,564. Electric heating panels and plates. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST.-GOBAIN, CHAUNY & CIREY. June 9, 1954 [June 23, 1953], No. 16983/54. Class 39 (3). A glass plate or panel 1 has a heating element of aluminium or aluminium alloy sprayed on to one of its surfaces, the element being in the form of laterally spaced closed loops 7 connected in series near their centres. When the panel is used in an upright position, the top half of the panel tends to become hotter than the lower half due to convection, and the resistance of the upper section of each loop 7 becomes greater than the resistance of the lower section, the resulting reduction of current in the upper loop sections counteracting the convection effect. Non-uniform application of the resistance material and consequent development of hotspots is also compensated for by the seriesparallel heater circuit. In a further embodiment, Fig. 2 (not shown), a food warming tray is provided with a thermostat for controlling its overall temperature, but local overheating is counteracted as before. The heater may be used for warming clothes. Specification 706,606 is referred to.

Abstract: In the synthesis of hydrocarbons and oxygenated compounds by contacting a mixture of carbon monoxide and water vapour in a ratio by volume of at least 2 : 1 with a Group 8 metal catalyst at 150-350 DEG  C. and 0-100 atmos. gauge, the catalyst being previously activated with carbon monoxide and hydrogen at 150-350 DEG  C., as in the parent Specification, the space velocity of the reactants (expressed as vols. per unit vol. of catalyst per hour) is at least 9 times the numerical value of the synthesis pressure in atmos., preferably 9-14 times.  To yield mainly hydrocarbons, the ratio of CO : H2O may be about 3; to give appreciable yields of alcohols, the ratio is less than 3.  The water may be introduced as liquid in one or more positions to dissipate the heat of reaction.  Hydrogen may also be introduced to react simultaneously with the carbon monoxide. The catalysts and synthesis conditions are as in the parent Specification.  In an example, operating pressure is increased from 10-70 in steps of 10 atmos. and space velocity from 175-800.

[Class 1 (i)] Bituminous substances, i.e. solid, liquid or gaseous hydrocarbons of aliphatic, naphthenic, or aromatic composition including pitches bitumens, bituminous fuels, e.g. pit coals, lignites, peat and oil shale, are depolymerized at temperatures substantially below their decomposition point by subjecting them to the action of sound waves of supersonic frequency. The treatment may be carried out in presence of hydrogen or gases containing hydrogen and in the presence of catalysts. The supersonic sound waves may be produced by reversal of , the piezo-electric effect by means of a' piezo-electric crystal of quartz or the like to which a high frequency electric current is connected. Spindle oil, e.g. a mineral oil boiling between 280 and 380‹ C. is distilled under vacuum and the vapours treated in the form of mist at 150-200‹ C. with supersonic waves of frequency 350 Kilo herz. A reduction in the boiling range of the fraction is obtained.
