IPC: F01K11/02
Filed: 1960-07-21
Abstract: 920,287. Steam turbines. ENGLISH ELECTRIC CO. Ltd. July 20, 1961 [July 21. 1960]. No. 25504/60. Class 110 (3). A multistage steam turbine comprising aligned high, intermediate and several low pressure cylinders driving directly an electric generator has the low pressure stage exhaust chambers and the condenser joined together to form a bridge structure supported at its ends by the support for the high and intermediate pressure cylinders at one end and the support for the electric generator at the other and by springs arranged between the underside of the condenser and the concrete floor of the pit. The high and intermediate pressure cylinders 1 and 2 and three double exhaust low pressure cylinders 12, 12<SP>1</SP>, 12<SP>11</SP> are arranged in alignment and drive directly the alternator 4 and exciter 5 of the generator. The condenser 9 is joined to the exhaust chambers 10 to form a bridge structure supported at one end from the concrete block 6 carrying the high and intermediate pressure cylinders 1 and 2 and at the other end by the concrete block 7 carrying the generator. The condenser is also supported by the springs 11 on plinths 16 in the pit 8. The bridge structure is strengthened by the water boxes 14 along its sides and rests on pads R, S, T, U on the blocks and is keyed at A and B to prevent axial movement and at C and D to prevent lateral movement. The intersection X of the line through the keys is therefore a fixed datum and all parts of the turbine are keyed, such as at V, to allow expansion longitudinally from this point but to prevent lateral displacement.

Title: Improvements in cinematographic machines
IPC: G03B21/46
Filed: 1931-09-11
Abstract: 389,496. Kinematograph projectors. ALLGEMEINE ELEKTRICITATS-GES., 2, Friedrich Karl-Ufer, Berlin. Sept. 11, 1931, No. 25561. Convention date, Sept. 16, 1930. [Class 97 (i).] In projectors comprising a spindle geared to upper and lower continuous-feed sprockets and to the pin wheel of a maltese cross mechanism, the pin wheel being capable of rocking about the maltese cross for film centring, the spindle moves vertically during rocking movements of the pin wheel, and centring is effected without change in the size of the film loops or of the phase relation of the cross and pin wheel. As shown, the spindle 4 is driven by a pin-and-slot connection with a motordriven shaft 20 directly driving a shutter shaft 21. The spindle 4 carries worms 17, 16, 11, respectively driving the upper and lower sprockets 2, 3 and the intermittent mechanism, and is mounted in bearings 5, 6 on a bracket 7 so as to be movable vertically with it by gearing from a hand-wheel 10. The worm 11 meshes with a helical wheel 12 which is loose on a sleeve extending from a casing 19 containing the pin-wheel and maltese cross, and drives a helical wheel 13 on the spindle of the pin wheel ; the worm 11 and wheel 13 are of equal diameters. The bracket 7 carries a rack 18 engaging a wheel 14 secured to the sleeve and equal in diameter to the wheel 12. Vertical movement of the bracket and spindle for film-centring rocks the casing 19 and pin wheel about the axis of the maltese cross by means of the rack 18 and wheel 14, and the movement of the worms 17, 16, 11 relative to the wheels they engage, rotates these wheels and the sprockets, to maintain the lengths of the film loops and the phase relation of the pin wheel and maltese cross ; the shutter drive is unaffected by the adjustment for filmcentring.

Title: Improvements in or relating to apparatus for electrolytically decomposing liquids
IPC: C25B15/08
Filed: 1937-10-04
Abstract: 503,483. Electrolysis. SIEMENS & HALSKE AKT.-GES. Oct. 4, 1937, No. 26842. Convention date, Feb. 5, 1937. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 22, 1938.] [Class 41] In an apparatus for electrolytically decom. posing liquids, the outlet conduit for at least one of the gases evolved communicates with a return conduit leading to the cell chamber, the return conduit having a nozzle the mouth of which is disposed slightly above the level of the electrolyte so that liquid electrolyte is carried into the said nozzle by the outflowing gas and flows back through the return conduit to the cell. The mouth of the nozzle may be surrounded by a check device consisting of a small container with a perforated bottom which serves to prevent excessive fluctuation in the level of the electrolyte alternately closing and opening the said mouth. In the embodiment shown in Fig. 1, water is electrolysed in a cell b mounted in a container a. The hydrogen liberated flows into the space d, and thence into the nozzle g, carrying some electrolyte with it, which electrolyte returns through the pipe f to the cell b, while the hydrogen is drawn off through the pipe e. A rising tendency in the level of the electrolyte at the mouth of the nozzle g may be maintained if the apparatus has a circulating arrangement in one gas space only, by maintaining a higher gas pressure in the other space, or if a circulating arrangement is present in each gas space, the rising tendency may be maintained by liquid balancing means. For example in Fig. 1, in which the circulating arrangement is shown for clarity in one gas space only, an electrolyte equalizing vessel i is in communication with the container a through a pipe m. If the level of the electrolyte in the container a falls, the level in the vessel i also falls and uncovers the end of the pipe connecting the-vessel i with the electrolyte make-up vessel l, whereby gas flows from the pipe k (which is connected with the pipe e) into the vessel causing fresh electrolyte to flow through the pipe n into the cell b and container a.
