Title: Improvements in or relating to self-supporting containers of carbon or graphite
IPC: B65D85/84
Filed: 1954-02-12
Abstract: 784,634. Tanks &c. CONRADTY, E. K., CONRADTY, P., CONRADTY, M., and CONRADTY, C. Feb. 12, 1954 [Feb. 13, 1953], No. 4269/54. Class 69 (1). A self-supporting container comprises a base portion and a wall portion each built up from a plurality of carbon or graphite plates a, those forming the wall portion providing longitudinally extending sections, the opposing ends of which are shouldered so as to internest or provide a groove c for sealing cement, those forming the base portion being tongued and grooved to engage one another and being cemented to the wall portion. Bands d of hard rubber or like resilient material are provided for each joint, and the base-plate surround a core piece e. In a modified form, the joints are plane and each wall plate is grooved to receive a retaining ring of carbon or graphite. The container may be spaced from the inner walls of a metal, concrete or other tank or vessel by a frame or cage which may also serve to guide a heating or cooling fluid in the interspace.
Patent GB-721291-A (GB)
Title: Improvements in or relating to variable condensers
Inventor: DAVIDSON WESTLAND
IPC: H01G5/06
Filed: 1952-02-20
Abstract: 721,291. Variable condensers. PYE, Ltd. May 4, 1953 [Feb. 20, 1952], No. 4497/52. Class 37. In a variable condenser of the interleaving vane type, either the static or the moving vanes are moved axially as the overlap is varied to diminish the minimum distance between any fixed vane and any moving vane with increasing capacity and to give a desired law of variation. This gives a high maximum capacity while retaining high voltage rating at minimum capacity. In one arrangement, this motion is produced by fixing to the shaft 8, which can slide axially in its bearings 7a, 7b, a projecting pin 12 which is constrained by a coil spring 15 to move over a profiled surface 13, mounted in the end plate. The coil spring is mounted between the flanges on the sleeves 14a, 14b respectively. These sleeves, one of which is fixed to the shaft, have engaging semicircular projections so that they rotate together but have independent axial movement. The second sleeve is free on the shaft but its collar is held against the end plate by the spring, its purpose being to provide a rotating bearing surface for the spring, thereby preventing it from twisting, which would cause backlash. Alternative methods are mentioned wherein the pin is constrained to follow a helical groove in a cylinder fixed to the end plate. In another embodiment the shaft bearing is threaded, the shaft being correspondingly threaded to give combined rotation and axial motion. Alternatively the stator plates may be geared to the rotor so as to be moved axially.

Title: Improvements relating to power transmission gearings
IPC: F16H61/02
Filed: 1950-02-23
Abstract: 677,099. Variable-speed gearing. DAIMLERBENZ AKT.-GES. Feb. 23, 1950 [Feb. 23, 1949], No. 4723/50. Class 80 (ii). Auxiliary epicyclic change-speed gearing for motor vehicles, comprising a planet carrier 5 secured to a shaft 1 connected to the output from the main gear box, an annulus 9 on the final driven shaft 3 and a reaction sun 8, has a one-way clutch 16 between the shafts 1, 3 so as to effect direct drive when the shaft 1 is driving forwardly and a one-way detent 17 between the sun 8 and the stationary housing 14 so as to effect an overdrive when the shaft 3 is driving forwardly, an armature disc 11 on the sun 8 cooperating with electromagnets 12, 13 in the housing 14 and annulus 9 respectively so that, when magnet 13 is energised, direct drive is effected when either shaft 1 or 3 is driving forwardly, while, when magnet 12 is energised, an overdrive is effected when either shaft 1 or 3 is driven forwardly. In order to permit rearward travel of the vehicle, the detent 17 must be rendered inoperative by withdrawing a pawl 19. Reverse drive can then be transmitted from shaft 1 to shaft 3 (direct drive) when magnet 13 is energised, while reverse drive can be transmitted from shaft 3 to shaft 1 (direct drive) when magnet 13 is energised or both magnets are de-energised. The pawl 19 may be withdrawn automatically upon engagement of reverse gear in the main gear box, and the magnet 13 may be energised automatically upon engagement of middle speed or reverse.

Patent GB-1122912-A (GB)
Title: Improvements relating to aluminum base alloy plates
IPC: B21B3/00
Filed: 1966-02-03
Abstract: A method of making an aluminium base alloy plate comprises providing a body containing 3% - 6% Cu, 0.8% - 3% Mg and 0.3% - 1% Mn, apart from impurities, the balance being Al and the magnesium content being governed by the relation: Mg min = 0.32 Cu when Mn is not greater than 0.5% Mg min = 0.2 + 0.32 Cu - 0.4 Mn when Mn is greater than 0.5%, the body having a length to base ratio of at least 2:1.  The body is heated to at least 800 DEG F. to homogenize its internal structure and is then forged a biscuit having a height of not more than 40% of the original body length.  The biscuit is reheated to 600 DEG  - 900 DEG  F. flattened slightly on its sides and further compressed in the original direction into a slab having a thickness of not more than 3/4 of the biscuit height.  The slab may then be cooled to room temperature. Subsequently it is hot rolled at 600 DEG - 900 DEG  F. to the final plate thickness of 1" - 8".  If the stock cools excessively during a hot working operation, it may be interrupted for reheating.  To develop high strength and hardness, the plate is solution heat-treated at 800 DEG  - 950 DEG  F. for 1-12 hours, then quenched and artificially aged at 300 DEG  - 400 DEG  F. for 6 - 24 hours.  The aging step is preferably preceded by stress relief comprising applying a permanent stretch of 1 1/2 - 3% at substantially room temperature.
