A rotary intermeshing lobe type of machine comprises a hollow elliptical cross-section major rotor 2, Fig. 1, and two flanking approximately figure-8 cross-section minor rotors with the axes of the rotors in a common plane and contact between the rotors and between the rotors and the casing substantially fluid-tight. A main shaft 36, Fig. 2, drives the major rotor direct and through identical gears 28 the minor rotors when the machine operates as a compressor, and is used to drive a load when the machine operates as a motor. Inlet ports 8, one to each minor rotor, are located in an end wall 26 at one end of the housing 6 on opposite sides of the common plane and outlet ports 10, one to each minor rotor, similarly in an end wall 40 at the other end of the housing 6 so that air flow is uni-directional to produce a substantially uniform temperature gradient axially of the rotors and so simplify design. Oil in a chamber 34 lubricating the gears 28 is thrown about by the gears and collected in a reservoir 46 whence through oilways it lubricates the bearings and the rotors. The machine is supported by three lugs 52. The compression ratio of the compressor may be varied by replacing the ends 26, 40 by others having differently-shaped ports.

Abstract: 1462104 Elevating apparatus WOODWARD MFG & SALES CO Inc 20 March 1974 [2 July 1973] 12407/74 Heading B8L [Also in Divisions B7 and F2] A two-wheeled hand truck comprises an outer frame 10 on which wheels 50 are mounted and which includes side members 12, 14, and an inner frame 26 which is movable relative to the frame 10, an angular load-engageable toe plate 35 being attached to the lower end of the frame 26, movement of the frame 26 being effected by means of a screw shaft 60 which extends from the drive shaft of a D.C. electric motor 66 mounted on the frame 10 to a bearing 62 also mounted on the frame 10, the screw shaft 60 passing through a bearing nut 54 located at the top of the frame 26, the direction of rotation of the screw shaft 60 by the motor 66 and thus the direction of movement of the frame 26 being controlled by switches 81, 82 which produce upward and downward movement of the frame 26 respectively. A brake mechanism (99), Fig. 4 (not shown), comprises a brake drum (100) which surrounds the screw shaft (60), the drum (100) being engaged by a brake shoe (103) with sufficient force to prevent rotation of the screw shaft when the motor 66 is inoperative, the latter overriding the brake action of the shoe when actuated. The side members 12, 27 of the frames 10, 26 respectively are of C-shape in section, the open sides of which face each other so that rollers 34, 32 which are mounted on the frames 10 and 26 respectively can run in the adjacent side member of the other frame. The truck may be used for moving a load up and down stairs by engaging its wheels 50 with a particular stair tread, e.g. stair tread (144) in Fig. 12 (not shown) and then raising or lowering the bottom of the frame 26 into engagement with a lower stair tread to permit the frame 10 and thus the wheels to be raised or lowered into engagement with a further stair tread, and repeating the sequence. The truck may also be used to raise and lower a load onto and from the back of a truck (136), Fig. 9 (not shown).

In a safety razor in which the blade can be stropped while in the razor by moving the latter to and from along the strop, the blade-holding and stropping members are carried by a rectangular yoke 9 mounted on a screwed shank 7 disposed in a handle 1 carrying a divided guard 3 between the parts of which the yoke is slidable. Strop-guiding rollers 11, 16 are journaled in the arms of the yoke and the roller 11 is geared to a blade-holding roller 11<a> also journaled in the yoke and carrying recessed pins 13 for engaging the perforations in the blade, while the cross-piece 8 of the yoke also carries blade-engaging pins 10. For shaving, the shank 7 is rotated to move the guard against the blade which is carried on to the pins 10 and clamped in position, the rollers 16 moving within the gap between the parts of the guard. For stropping, the guard is moved to release the blade from the pins 10 and expose the rollers 16 and the blade is secured on the roller 11<a> by moving it laterally so that the recessed pins 13 engage the blade which can then be sharpened on a strop 17 passed between the rollers 11, 16. In a modification, the cross piece of the yoke is detachable and for sharpening the blade is secured on a separate carrier held on the roller 11<a>, one edge of the blade being sharpened at a time.

Title: Improvements in or relating to the catalytic treatment of water gas with steam to increase its hydrogen content
IPC: C01B3/16
Filed: 1951-05-29
Abstract: In a process for increasing the hydrogen content of water gas, steam which may be slightly superheated is introduced into the hot water gas as it leaves the generator thereby reducing the temperature of the gas to a level suitable for conversion of carbon monoxide and steam into hydrogen and carbon dioxide by means of a powdered catalyst which is also introduced into the water gas; after the resulting conversion the gases are freed from the catalyst, cooled, washed with water under pressure and treated for removal of hydrogen sulphide by a dry process.  The powdered catalyst may be utilised repeatedly and may be introduced into the water gas by means of the steam.  Suitable catalysts are oxides of calcium and magnesium and iron oxide containing substances such as for example meadow iron or red sludges.  A temperature of 450-470 DEG C is suitable for the conversion.  In a modification water may be sprayed into the hot water gas to form the steam for the conversion any heat required being obtained by partial combustion of the water gas by means of an addition air, oxygen or a mixture of air and oxygen.
