Title: Improvements in marine power plant
Inventor: BAILEY RICHARD WILLIAM
IPC: F01K23/06
Filed: 1949-10-21
Abstract: 682,003. Motor power plant; elastic fluid turbines. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Sept. 29, 1950 [Oct. 21, 1949], No. 27135/49. Class 110 (iii) [Also in Group XXXIII] In a marine power plant for driving two or more screws 10, 20 wherein each screw is driven by a set of intermediate- and low-pressure turbines such as 12, 12<SP>1</SP>, 13, 13<SP>1</SP> and 22, 221, 23, 23<SP>1</SP> respectively, the turbine sets are arranged in parallel with a single high-pressure turbine 31 which is coupled through electric transmission means to drive the screws or a further load shaft or both screws and load shaft. The screws are also driven by electric motors 15, 25 and Diesel engines 14, 24. The electric motors are energized by a generator 30 which is driven by the steam turbine 31 and a low-pressure gas turbine 32. The gas turbine plant also comprises a compressor 34, an air heater 35, a combustion chamber 36 and a high-pressure gas turbine 37. The steam generator 33 is fed with exhaust gasses from the Diesel engines and the gas turbine plant. In a marine power plant having an odd number of screws the turbines 31, 32 either provide all the power for the central screw or assists in driving all the screws. The turbine 32 may drive the load shafts independently of the turbine 31 through suitable gearing. Should the electrical transmission system fail the intermediate- and. low-pressure turbine sets are supplied directly from the generator through pressure reducing means and the gas turbine 32 is by-passed by a valve 38. Specifications 602,573, 666,453 and 682,002 are referred to.

Title: Improvements in electronic devices for pulse telecommunication systems
IPC: H04B14/06
Filed: 1965-06-28
Abstract: 1,106,042. Delta modulation systems. COMPAGNIE FRANCAISE-THOMSON HOUSTON-HOTCHKISS BRANDT. 28 June, 1965 [1 July, 1964], No. 27367/65. Heading G4H. In a delta modulation system in which characteristic pulses representing positive and negative increments of the input signal are transmitted, the input 10 is applied to an adding circuit 11 in phase opposition to the output of an integrator 14 which is fed with a positive or a negative pulse from detector 12 or 13 each time the input varies by an amount exceeding one increment. The positive and negative pulses from detectors 12, 13 are applied to encoders 17, 18 to produce characteristic pulse groups or position-modulated pulses for transmission. The receiver separates the positive and negative pulses and applies them to an integrator similar to integrator 14 in the transmitter. In another embodiment, Fig. 3, 4 (not shown), the outputs of detectors 12, 13 are gated with clock pulses and the gated output of 13 is delayed a predetermined amount before transmission. At the receiver, an inverter is controlled by clock pulses of twice the repetition frequency of the transmitter clock, the output of the inverter is integrated, and the D.C. level obtained from the integrator is used to ensure phase synchronism of the receiver clock generator.

Filed: 1945-10-18
Abstract: 625,099. Coated fabrics. MERTENS, M. Oct. 18, 1945, No. 27432. Convention date, Dec. 21, 1942. Drawings to Specification. [Class 140] [Also in Group XXVIII] Protective sheaths are made from fabrics in which the weft threads are woven obliquely to the warp by forming the fabrics into cylindrical or conical shapes then shaping the latter to the desired forms and maintaining this form by treating with a dressing of sizing materials or by impregnation, but allowing the form to retain sufficient flexibility to allow temporary deformations. The shaping of the cylindrical or conical forms may be effected by folding the sheath or by girding the sheath with wires, threads or rings and inflating portions of the form between the girded regions. The cylindrical or conical forms may be shaped by pulling them on to a model or mandrel, binding the sheath to the shape of the mandrel and after impregnation withdrawing the mandrel. The impregnating materials may be gelatine with glycerine or glycol, or synthetic resins with or without plasticizers. The sheaths may be used for protecting cardan joints, ball-and-socket joints, door knobs and for bellows.
