Abstract: 288,477. Young, J. H., and Robertson Co., H. H. Aug. 30, 1927. Testing ventilation.-Apparatus for comparing the efficiencies of various types of ventilating- cowls comprises an air stack 15 so arranged at the outlet end of an air tunnel 12 that a current of air passing through the tunnel acts upon a miniature ventilating-cowl detachably mounted on the stack and induces an updraught in the stack in a manner analogous to that in which the wind draws air &c. through the eduction pipe of the corresponding full-sized ventilating-cowl when in position. The stack 15 is mounted in a block 17, which has a removable cap 18, and is adapted to slide in guides on the base a so as to permit different sizes and forms of miniature cowls to be tested. The mounting of the pipe 15 also allows the latter to be moved into different angular positions.

Title: Improvements in and relating to the purification of gas mixtures
Inventor: CHALLIS ANTHONY ARTHUR LEONARD
IPC: B01J23/40
Filed: 1958-07-16
Abstract: Propylene containing methylacetylene is purified by passing with hydrogen over a catalyst containing 0,01-0,1% of a Group VIII metal on gamma alumina and optionally an alkali metal salt at 100 DEG -120 DEG C.; allene and vinylacetylene if present are also destroyed.  The catalyst preferably contains palladium introduced by impregnation and sodium oxide introduced by impregnation with sodium carbonate; the catalyst is preferably first heated in hydrogen at 400 DEG  C.  The amount of hydrogen is small, e.g. 1 mole per 100 moles propylene and may be mixed with the propylene by contacting liquified propylene with a mixture of 95% nitrogen and 5% hydrogen, e.g. at 250 p.s.i. to dissolve sufficient hydrogen. The liquid is vapourised and the gas passed over the catalyst at a rate of 500-1500 litres per litre of catalyst filled space per hour.

Abstract: 644,425. Operating clutches; change-speed gear. B.S.A. TOOLS, Ltd., and OGILVIE, W. Aug. 16, 1947, No. 22812. [Class 80(ii)] [Also in Group XXIII] In a centreless grinding machine having a control wheel with a non-circular periphery, the grinding operation on a work piece being completed during one revolution of the control wheel, the rotation of the control wheel is stopped after one revolution to permit feeding of a work piece to the machine by hand. The control wheel 4 is mounted on a shaft 7; a sleeve 15 is slidably keyed to a sleeve 11 secured to the shaft 7 so as to be movable longitudinally. The sleeve 15 is urged by a spring 72 to its right-hand position in which dog teeth 17 on the sleeve engage dog teeth 27 on a worm wheel 25 meshing with a driving worm 26. The sleeve 15 carries a face cam 20 which co-operates with a pin 51 to move the sleeve 15 to the left thus disengaging the teeth 17, 27 and stopping the rotation after one revolution. To initiate the next revolution, the pin 51 is withdrawn, against loading spring 54, by means of a chain :57, link 60, lever 61, push rod 63 and knob 64. By means of a handle 47 the sleeve 15 can be moved, against the spring 72, into its extreme left-hand position, in which dog teeth 18 on the sleeve engage dog teeth 31 on a helical gear 29 meshing with a driving gear 30, whereby the control wheel can be rotated faster during trueing operations.

Abstract: 261,343. British Thomson-Houston Co., Ltd., (Assignees of Barton, F. C.). Nov. 14, 1925, [Convention date]. Thermionic amplifiers. - In an amplifier associated with a loudspeaker and worked from the house lighting mains, the voltages for the filament and plate are derived from the voltage drop across resistances in the supply circuit, a voltage-limiting device is plugged in simultaneously with the closing of this circuit, and the polarizing winding of the loud speaker constitutes a choke for eliminating current ripples, in co-operation with smoothing condensers. Alternating current is supplied to the terminals a, b, through the primary 2 of a transformer, ballast lamp 46, and sockets 3, 4, which are normally bridged by a wire 48, Fig. 2, connecting the plugs 3', 4<1>, of the neon tube or other voltage limiting device 38. The secondary supply circuit, from which the required voltages are tapped, includes the secondary coil 7, rectifiers 13, 14, polarizing winding 10 of the loud speaker, and resistances 24, 22, 23, 20, of which 20, 22, are shunted by bypass condensers. Smoothing condensers 36, 37, co-operate with the winding 10 to eliminate current ripples. The oscillations to be amplified are applied through the terminals 17 to the grid of the first valve 8, the bias of which is derived from the resistance 20. The filament current is derived from the voltage drop in the resistance 22. The output of the valve 8 is applied to the grid of the second valve 9 through a transformer 27. The plate circuit of the valve 9 passes from the filament 16 through the secondary 15, lead 47, resistance 33 with by-pass condenser 34, resistances 22, 24, and primary of the transformer 45 to the plate 35. The high tension is derived from the voltage drop in the resistances 22, 24r the grid bias from the voltage drop in the resistance 33, and the output of the transformer 45 is applied to the operating coil 41 of the loud speaker. The voltage limiting device comprises a glow tube 38, Fig. 2, having its electrodes connected to plugs 29', 30<1>, for insertion in the sockets 29, 30 : the supply circuit is broken at 3, 4, unless the safety device be plugged in, and the plugs 3<1>, 4<1>, 29<1>, 30<1> are sized to preclude insertion in the wrong position.

[Class 83 (iv).] Working at specified temperatures.-In the hot extrusion of metals, a plunger speed exceeding 5 inches per second is employed for a billet having a height from 2 to 2¢ times its diameter. A press comprises a crank-actuated ram 11 carrying the piercing mandrel 12 and adapted to engage the inner wall of the ram 13 carrying the extruding plunger 14 after piercing has been effected. The billet after piercing may have a diameter 4.05 inches and a height 9.05 inches, the extrusion taking place in the last 56‹ of the second quadrant of the stroke of the crank which revolves at 6.2 revolutions a minute. The average speed of extrusion is thus 6 inches per second. A steel billet may be heated to 1270‹ C. before insertion into the container 4. A time-pressure curve indicates that the initial total instantaneous pressure is about 1,200,000 lbs., falling to about 900,000 lbs. and remaining fairly constant during the operation, but rising rapidly towards the end. It is stated that articles of small wall thickness or cross section may be obtained with this process.

The wires 34 in each unit pass through holes 42 in the body with their bored ends lying along the base of parallel open grooves terminating in end pieces 74. The wires are made of a metal which will easily oxidize to form a thin oxide surface film In each probe 180 spring contacts 190 are arranged in opposed rows to receive the shelf 94 and its associated units 32 between them, contact being made by the bent sections 192 of the contacts pressing on to the wires 34 where they are exposed in the open grooves, the oxide surface film being ruptured by the spring pressure. The end pieces 74 may be of varying lengths so that certain springs 190 are permitted to make contact with certain of the exposed wires before the others as the probe is inserted. Each wire holding unit 32, Fig. 8, has a flap 50 which can be raised to assist in the positioning of the wires.

In a level-luffing crane in which the jib comprises two parts 5, 7, the luffing gear 9, 10 is fixed to a supporting frame 8 pivotally mounted on the pivot shaft 4 of the jib 5. The crane is pivotable through 360 degrees on a column 2 and is luffed by spindle and nut mechanism 10 connected to the jib at 11. A lifting rope 13 extends between a winch 12 and a block 18. To lower the jibs into an inoperative position, in which the jib 7 serves as a prop for the jib - 5, the lifting block 18 is first lowered to the level of the pivot shaft 4. The free end of a rope 21 which passes round a block 19 is taken over guide and auxiliary pulleys 22, 23, 23a and connected to a rope 25 at 24, the other end of rope 25 being fixed at 26. Operation of the winch 12 draws the rope 21 into the position shown. Straps 27 between the frame 8 and the frame 3 are now disconnected and the lifting cable paid out to lower both jibs to inoperative position, Fig. 2 (not shown). The jibs are erected by reversing this procedure. The rope 21 may be connected directly to the lifting hook or hooks, in which case the auxiliary rope 25 is not required.
