Title: Improvements in gas-collecting means for electrolytic aluminium smelting furnaces
IPC: C01B32/40
Filed: 1956-09-07
Abstract: 814,413. Electrolytic furnaces. ELEKTROKEMISK A. S. Sept. 7, 1956 [Sept. 12, 1955], No. 27528/56. Class 39(3) [Also in Group XXXVI] In a furnace for the electrolytic smelting of aluminium, the gas evolved at the electrode is collected in concentrated form and immediately passed in the unburnt state to a delivery pipe via an adjacent washing chamber in which the gas is washed with a suitable liquid so as to remove its tar constituents. As shown, an electrolytic furnace comprises a pot 1 provided with a continuous electrode 2 enclosed by an iron casing 3 and an annular gas collecting chamber 4 to which is attached a gas outlet pipe 5, 6 having cleaning doors 7. The downwardly extending pipe 5 leads into a vertical washing pipe 9 of larger diameter, the inside walls of which are flushed with liquid injected through sprays 8 situated above the open end of the pipe 5. A collecting tank 10 for the washing liquid is provided at the foot of pipe 9 and washed gas is delivered to a gas manifold 11. The water pipes are preferably made of insulating material and the pipe 9 and manifold 11 are provided with linings, e.g. of rubber, resistant to acid gases. The washing liquid may be water alone, water with fluoride binding agents, e.g. CaHCO 3  or Na 2 CO 3 , or anthracene oil or similar organic liquids, e.g. trichlorethylene, and may be regenerated and re-cycled through the washing process. The washed gas, containing 60-70 per cent CO and 30-40 per cent CO 2  may be recirculated through the gas collecting pipes during the stoking of a furnace to reduce the risk of explosion.

Title: Rotary mechanisms including locking devices
IPC: F16D9/02
Filed: 1977-07-01
Abstract: A device, especially for the bearings of idler rollers of underground coal conveyors in collieries, to lock the two halves of a bearing against further rotation when the bearing overheats. Overheating causes a fusible plug, mounted on one half of the bearing, to melt and release a catch member which engages with an abutment on the other half. The plug may be designed so that when it has once fused so as to lock the two halves, it still prevents them from resuming mutual rotation even if it solidifies again.

Abstract: 953,549. Tunnel diode bistable circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 3, 1961 [Aug. 10, 1960], No. 27733/60. Heading H3T. [Also in Division G4] A tunnel diode binary storage unit comprises (Fig. 2) two potential dividing circuits R1, R2, R5 and R4, R3, R5 with the tunnel diode TD connected to a tap A. Writing is by application of a positive pulse followed by a negative pulse at point 3 which if point 1 is held negative will switch TD first to its low-voltage and then to its high voltage state (since R5 is large TD operates as a constant current bistable element). If L is held at earth potential the negative pulse will be by-passed and TD will be left in its low-voltage condition. Interrogation is non-destructive; a negative pulse at 4 insufficient to switch TD will, if it is in its high voltage state, lower the potential at D2 sufficiently for the latter to conduct and provide an output at 2. Fig. 3 shows a matrix of units into which a row of data can be written by supplying a signal on an " S " wire and selectively energizing the appropriate " W " column lines. An interrogation pulse on an " I " line provides outputs at R.

Abstract: 1,114,534. Pulse shaping circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 24 June, 1966 [29 June, 1965], No. 28295/66. Heading H3T. A circuit for converting distorted input pulses produced by mechanical contacts 1 into undistorted output pulses comprises a bi-stable circuit 15, 20 with a timing capacitor 10 connected in the regenerative feedback loop. The arrangement is such that when contact 1 is open, transistor 15 is saturated and capacitor 10 is charged through resistor 6 towards the negative potential of battery 7. When contact 1 is closed, point 5 is earthed, thus reverse biasing diode 8. Capacitor 10 then charges through resistor 14 and transistor 15 until it reaches sufficient potential to change the state of bi-stable circuit 15, 20. When the contacts are again opened, capacitor 10 discharges through diode 8 and resistor 6 until its potential is such as to again change the state of circuit 15, 20. Undistorted pulses are thus provided at the collector of transistor 20, the short peaks occurring at the leading and trailing edges of the input pulse and resulting from contact bounce being too short to alter the charge on capacitor 10 and hence cause spurious triggering of the bistable circuit.

Title: Improvements in and relating to film driving means for use in sound recording or reproducing apparatus
IPC: G11B7/00
Filed: 1929-09-18
Abstract: 319,246. British Thomson-Houston Co., Ltd., (Assignees of Heisler, C. L.). Sept. 18, 1928, [Convention date]. Film-feeding mechanism. - Mechanism for driving a sound-record film past the recording or reproducing device comprises a drum, an idler, and a driven member, the film passing over each of these members in turn. To prevent excessive tension in the film and, where the driven member is a sprocket, to eliminate irregularities in the driving action of the sprocket, the driven member assists in driving the drum through friction rollers. In the apparatus shown, which is for reproducing sound from a combined picture film and sound record, the film 1 passes over a drum 5, an idler roller 22, and a sprocket 20 which is driven uniformly by means such as an electromotor. A friction roller 21, secured to the sprocket, engages with a roller 23 fixed on the idler shaft 24, and the roller 23 also engages a friction roller 17 mounted on the drum 5. The roller 17 is in frictional engagement with the drum, and is so held by a nut 18 that no slipping normally occurs. The shaft 24 is carried by a jointed pivoted bracket 25, 26, controlled by an adjustable spring 28. With the arrangement described, the drum is driven jointly by the film and by a positive connection through the friction rollers with the sprocket 20. The dimensions of the rotating parts are so chosen that the idler has a peripheral speed slightly greater than the speed of the film thereon; thus the tension in the part of the film between the idler and the sprocket is diminished. Optical apparatus.-The drum 5 is made in two parts 6, 7, mounted on a shaft 8 and spaced apart by a distance slightly greater than the width of the sound record 3 on the film. The part 7 is detachable. A narrow light beam is passed through the film on to a photo-electric cell 13, which is located within the drum. The cell is mounted on a bracket 14, surrounding a reduced part of the shaft 8 and supported by an arm 15 extending through the space between the parts of the drum.
