Filed: 1964-08-10
Abstract: 1,075,624. Rolling gears. NAUCHNOISSLEDOVATELJSKY INSTITUTE TEKHNOLOGII AVTOMOBILJNOI PROMYSHLENNOSTI. Aug. 10, 1964, No. 32534/64. Heading B3M. A gear blank 3 is formed with bevel teeth by being clamped to a face-plate and rolled by means of a toothed tool 4, the face-plate and tool being attached to meshing synchronizing wheels 1 and 2. The blank 3 is held in position by a clamp 8 and by an annular bead 9 which co-operates with the outer periphery of the blank. For cold-rolling there is no clearance between the bead and blank, but for hotrolling a small clearance is left to accommodate expansion of the blank after heating. Heating of the blank is conveniently produced by an H.F. induction heater (24), Fig. 7 (not shown), the blank being lifted from its position on the face-plate by rods (25) for the heating step. The rods are lifted by a sleeve (26), a bushing (29) and casing (15) being raised at the same time. Radially projecting spring-loaded fingers (14) retain the blank in its working position and are inwardly retractable by lowering a cam-ended rod (30). External clamps can act radially inwards of the blank to hold it in place.

Title: Improvements in Metering Devices.
Inventor: MOWL ARTHUR RICHARD
IPC: G01R21/00
Filed: 1966-07-20
Abstract: 1,167,903. Metering. ENGLISH ELECTRIC CO. Ltd. 18 July, 1967 [20 July, 1966], No. 32535/66. Heading G4H. [Also in Division G1] A metering device includes two toothed members 5, 6 (Fig. 1), which rotate, at a rate determined by the quantity being metered, in the air gap of two magnetic sensors 8, 9, two oscillator circuits 17, 18 (Figs. 1 and 3) detecting the presence of a tooth in the air gap of the associated sensor to switch a bi-stable device 19 to one stable state when a tooth is in one gap and the other stable state when a tooth is in the second gap. The pulse output from the bi-stable is fed to a counter. The apparatus may be used for measuring the quantity of electricity consumed or fluid flow. In the embodiment described as a tooth enters the gap in the sensor 8 (Fig. 1) the Q factor of oscillator circuit 17 (Fig. 3) is altered to decrease the voltage across resistance R2 and the capacitor C1 so that transistor T2 is cut off and transistor T3 is switched on. The bi-stable device 19 remains in this state until a tooth enters the air gap in the second sensor 9, thus rendering the apparatus insensitive to a certain amount of reverse "creep" of the input shaft driving the toothed members.

Abstract: 602,573. Hydraulic clutches. BAILEY, R. W., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Dec. 11, 1945, No. 33512. [Class 69 (ii)] [Also in Groups XXVI and XXXIII] In a ship's propulsion plant in which combustion products are used to generate steam for use in at least two steam turbine stages and are afterwards used as the working fluid in a gas turbine, as described in Specification 459,365, [Group XXVI], the gas turbine and the high-pressure steam turbine are not reversible and are connected to the same or separate propeller shaft through a reversible drive. In the plant shown in Fig. 1, a gas generator 1 delivers to a steam generator 2 and a superheater and reheater 3 in both of which further fuel is burnt. The products of combustion go by pipes 6, 7 to a gas turbine 8. Steam from the generator 2 goes to a superheater coil 10 and thence to a steam turbine 12. From that turbine it goes to an interstage reheater coil 14 and thence to a low-pressure turbine 15. For astern running, a low-pressure astern turbine 21 without reheating replaces the turbine 15 which then rotates idly. For cruising, the lowpressure turbine 15 may be cut out and the exhaust from turbine 12 sent by way of a precondenser 23 to the main condenser 17. The turbines 8, 12 may drive the propeller 28 through a reversible electrical transmission. Forward and astern toothed gearing may be provided with hydraulic clutches in both pinion shafts. The forward clutch may be associated with a positive clutch and have braking means for bringing the hydraulic coupling parts into synchronism prior to engaging the positive clutch. The gas and steam turbines may be on separate shafts with hydraulic clutches and separate driving pinions for forward running and geared to a third shaft with hydraulic clutch and pinion for astern running. The hydraulic clutches may be provided with friction creating surfaces such as overlapping rings on the two halves so that the empty clutches will maintain uni-directional contact between the gear wheel teeth. The gas turbine may be arranged to drive a middle propeller and the steam turbines two wing propellers so that the gas turbine alone or the steam turbines alone could be used.
