In propulsion means for waterborne vessels of the type in which air or gas is released in bulk into the water in a duct having an inclined upper surface, the duct is constituted by a member which is pivotally mounted about a horizontal axis for movement between oppositely inclined positions. An air chamber 35 is formed from top and bottom plates 36, 37 and side plates 38 which together with the plate 37 form an inverted U-duct 40. The chamber 35 is supplied with gas by a pipe 41 and has outlets 43, 44, controlled by valves 60, 61, to the U-duct. The chamber 35 is pivoted at 46 and is supported at one end by rollers in tracks 59. The angle of the plate 37 is adjusted by means of ropes 53 and the valves 60, 61 are automatically opened and closed as the angle is adjusted by being connected to rods 68, 69 secured to the frame 49 by which the device is supported from the vessel, which may be steered by rudders 52; alternatively, the U-duct may be longitudinally divided into separate ducts which may be separately supplied with gas.

IPC: C08L95/00
Filed: 1924-04-08
Abstract: 236,641. Mackay, H. A. April 8, 1924. Emulsions, making.-Bituminous emulsions, for use for example as a binding medium in roadmaking and in the manufacture of coal briquettes and for coating or impregnating stone, wood, metal, roofing felt &c., are prepared by mixing a molten or liquid bituminous material with a small proportion of a sulphonated fatty oil and adding hot water with or without alkali. Acid sulphonated oils may be neutralized such as with ammonia. A portion of the sulphonated fatty oil may be replaced by fatty acid, casein or other known emulsifying agent and in the case of using free fatty acid sufficient alkali is employed to neutralize such acid. As bituminous materials are specified Mexican asphalt, pitch, native asphalt or bitumen and coal tar or other tar and as alkalies caustic potash or soda, the corresponding carbonates and borax. In examples Mexican asphalt is melted and sulphonated cod oil with or without oleic acid or neutral, acid or alkaline alizarine oil is stirred in and finally the whole is mixed with caustic potash or soda and hot water. Apparatus of colloid mill type or of the type described in Specification 202,021 may be employed for the emulsification. Specification 24135/06 also is referred to.

Abstract: 576,860. Rotary carburizing furnaces. BIRLEC, Ltd. (formerly BIRMINGHAM ELECTRIC FURNACES, Ltd.), and HANCOCK, P. F. May 15, 1944, No. 9232. [Class 51 (ii)] In a carburizing furnace comprising a rotary drum 1 surrounded by a heating chamber 2, leakage of gas from the drum into the heating chamber is prevented by a stationary cylinder 3 which, in the form shown in Fig. 1 extends through the end walls of the furnace structure and terminates in sealing casings 9, 10. The former encloses a charging chamber 13 integral with the drum 1 and to which the work is fed from a hopper 11 fitted with a hinged cover 14, the work passing into the drum 1 through a spiral passage 21. The drum is formed with a conveying screw on its inner wall and has, at the discharge end, an aperture 6 which registers, once during each revolution, with a discharge shoot 7 integral with the cylinder 3 and delivering to a quenching tank 8. The chamber 13 is supported on rollers or pinions 15 driven through gearing 17, 18 from an electric motor 16, while at the opposite end the drum is carried by a hollow shaft 24 which rotates in a stationary plug 25 and is supported within the chamber 10 by rollers 29. A supply pipe 26 for carburizing gas extends through the hollow shaft 24. Fig. 3 shows a modification in which the axis of the furnace is inclined and the cylinder 3 is sealed at its lower and upper ends by glands 35, 36, the drum 1 projecting through the lower gland 35, and being enclosed within a stationary cowl 39 carrying a vertical pipe 42 at the upper end of which any gas leaking into the cowl is burnt. In a further construction, also having an inclined axis, the drum 1 and cylinder 3 extend at the lower end into a liquid sealing tank.

Title: Improvements in and relating to high frequency apparatus

Filed: 1940-05-27
Abstract: 541,271. Electron oscillators; resonators. BRITISH THOMSON-HOUSTON CO., Ltd. May 27, 1940, No. 9306. Convention date, May 27, 1939. [Classes 39 (i) and 40 (iii)] In an ultra short wave amplifier or oscillation generator a resonator surrounding an electron beam tube 60 comprises a number of spaced electrodes 73-77, Fig. 8, connected by end walls 85, 86 to an outer shell 83 ; the end walls are deformable for tuning. The length of the spaced electrodes is designed to give a resonant system such that when the resonator is in free oscillation the effect of the electrodes and gaps on a beam traversing the tube at the working voltage is cumulative. The lengths approximate to the time taken by an electron to travel a cycle or a multiple thereof the end sections 73, 77 being half this length; some electrodes may be longer than others. Formulae and a table are given to obtain the required dimensions. The gaps between the electrodes 73-77 are bridged by dielectric rings 78-81 and plates 96-99 on these rings allow for adjustment of the capacity of the gaps, the plates being all connected to a quartz rod 100; when a variation is effected a corresponding change is made in the electron velocity in the beam. The beam is formed by a gun 64-66 and electrodes 61 within the tube 60 maintain a uniform bias; these electrodes may comprise rings of colloidal graphite coated on the tube. Power is taken off by a plate 103 capacitatively coupled to the centre electrode 75 and connected to a concentric line 104, 105. The beam is maintained in focus by the electromagnets 65; a suppressor electrode 69 is placed before the collector 68. As an amplifier the input signal is applied to a concentric line 121, 122, Fig. 10, whose terminal plate 120 is coupled to the electrode 115 of an input resonator 118; this electrode is of a length wholly corresponding to the wave length; the modified beam passes through a second resonator 133 with output 141, 142. Instead of connecting the end electrodes to the end plates of the resonator these electrodes 160, 165, Fig. 13, may have extensions measured from a<SP>1</SP> to b<SP>1</SP> or a<SP>1</SP> to b, constituting quarter wave or multi-quarter wave transmission line sections; or this arrangement may be used with one end connected to the resonator. Tuning of this construction is obtainable by a ring 170, Fig. 15, adjustable on the electrode. With the arrangement shown in Fig. 13, the electrodes may be within the electron beam envelope 60. Specifications 518,015 and 533,500 are referred to.

Abstract: 574,087. Projectiles. POWELL, G. A. R. May 29, 1940, No. 9413. [Class 9 (i)] A device for cutting wire entanglements comprises a projectile, connected to a cable, having cutter arms which occupy a closed position during the forward trajectory, but are opened out before the projectile is hauled back to cut the wire. The opening of the cutters is effected by means of an electric motor fitted in the projectile, the motor being reversed to re-close the cutters for avoiding ground obstructions after the projectile has been hauled clear of the entanglements. As shown, a series of arms 6 fitted with saw-tooth blades 18 are pivoted at 5 on the forward part 2 of the shell-casing and normally occupy the folded position shown in broken lines. For opening and closing the cutters, a shaft 13, driven from the motor 15, is threaded into the boss 11 of a spider 10 fitted with pins 9 engaging arcuate slots 8 in extensions 7 of the arms 6. The hauling-cable 29, carrying the conductors for the motor, is swivelly-connected to a piston 19 which is slidably, but non-rotatably. fitted in the rear part 1 of the casing. Cushioning-springs 41, 42 are fitted between a sliding collar 40 and the piston 19 and a fixed end-nut 39.
