Title: Improvements relating to steam turbines exhausting into direct contact condensers
IPC: F01K11/02
Filed: 1931-11-25
Abstract: 384,072. Steam turbine plant. BELLISS & MORCOM, Ltd., Ledsam Street Works, and MASTERMAN, A. L., 41, Oakham Road, Harborne, both in Birmingham. Nov. 25, 1931, No. 32673. [Class 110 (iii).] A steam turbine exhausting into a condenser of the direct contact type is provided with means, actuated by the steam pressure, for shutting off the condenser until a suitable vacuum is reached, when the vacuum causes the hydraulically-operated shut-off valve to open. The exhaust steam from a turbine a, during normal running, is deflected radially by a cone c into contact with water sprayed by a series of nozzles e, and water and condensate pass through a pipe f and are extracted by a centrifugal pump g which is driven from the turbine shaft through bevel gearing h. The pipe f is provided with an expansion joint f<1> and support springs v. The vapour-extracting apparatus is connected to an outlet i from the condensing chamber d. During the running-up of the turbine the exhaust steam passes to atmosphere through a pipe b<1>, and a non-return valve. The conical plate c constitutes a valve which closes automatically when the vacuum is insufficient to draw water through the nozzles e. Water, under the pressure of the steam supplied to the turbine, passes through a pipe l to the underside of a piston sliding in a cylinder k to hold valve c closed. A relay valve m is formed of a vertically-sliding rod provided with piston surfaces m<1>, m<2> separated by a neck m<3>. A weighted lever o, pivoted at o<1>, tends to raise the valve m against the suction acting on the underside of a piston p which, through a pipe r, is open to the vacuum space of the condenser. When the required vacuum is reached the valve m moves downward and places the pipe l<1> into communication with a pipe l<2> which allows water in the cylinder k to flow into a drain tank n open to the atmosphere. The valve c then descends due to gravity and the pressure of the exhaust steam bearing upon it. A pipe s allows communication between the top of piston p and the tank n. The degree of vacuum to operate the valve m may be pre-arranged by adjusting the position of the weight on the rod o. In a modification a stationary deflector plate c is used and the piston-rod j acts through links to operate a butterfly valve placed between the turbine and the plate c. This leads to a multiplication of the hydraulic lines to control the piston k on both upper and lower sides. A further modification, also with a stationary plate c, describes a sluice valve operated by the rod j. The condenser shut-off valve may be provided with means for control by hand.

Title: Improvements in dimpling machines
Inventor: STATES RONALD FREDERICK
IPC: B21D22/04
Filed: 1958-10-14
Abstract: 876,425. Dimpling. DE HAVILLAND AIRCRAFT CO. Ltd. Sept. 25, 1959 [Oct. 14, 1958], No. 32791/58. Class 83 (4). A portable dimpling machine comprises a die having a centrally positioned retractable pilot pin, a rotatable punch bit lying opposite said die and an air-actuated motor for moving said punch bit into operative engagement with a sheet metal workpiece and for rotating the punch bit to form the metal to the profile of the die. Attached to the handle 2 of the machine is an air cylinder 4 containing a spring-loaded double piston 5 carried by a hollow piston rod 6. Coaxial with the cylinder 4 is the air motor 8 which terminates in a head 10 supporting the punch bit and carrying an interchangeable yoke 11 which includes the die 12 and its spring- loaded pilot pin 13. The cylinder 4 is divided into two compartments by a partition and each compartment contains a piston 5 axial movement of which imparts a similar movement to the air motor. A shaft 16 takes the place of the usual chuck on the motor spindle 17 and the shaft 16 carries a sleeve 19 slidable thereon within certain limits determined by a ring retainer 22 on the shaft which engages in an annular groove in the sleeve. Forward movement of the sleeve is restricted by an adjustable screw-threaded sleeve 25. The forward end of the sleeve carries an adjustable spring-loaded pressure pad 29 and the forward end of the shaft 16 contains the punch bit 30 provided with a frusto-conical face 33 terminating in a projection 34 which enters the hole in the workpiece and displaces the pilot pin 13 rearwardly. In operation the pressure pad and bit are advanced by the motor jointly until the pressure pad engages the workpiece the bit then advancing further and at the same time rotating to form the metal around the hole to the required dimple shape. Entry of compressed air to the motor by actuation of the trigger 3 causes the motor spindle to first of all rotate and then the motor as a whole to advance as the compressed air acts on piston 5. When the stroke is almost completed a thrust bearing 37 engages a shoulder 19a on the sleeve 19 thereby transmitting the total pressure of the air cylinder to the pressure pad to coin the metal around the periphery of the dimple. With the completion of the dimpling operation, the trigger is released and the spring 7 moves the piston air motor and punch unit away from the die and thereby releases the workpiece.

Title: Improvements in or relating to radio direction finders
IPC: G01S1/02
Filed: 1938-11-16
Abstract: 505,547. Directive wireless signalling. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Nov. 16, 1938, No. 33357. Convention date, Nov. 16, 1937. [Class 40 (v)] Relates to direction-finders of the kind in which a constantly-rotating or oscillating frame aerial a, b operates a direct-reading indicator, such as a discharge lamp z which glows either at the maximum or minimum points. When such a system is used on board ship, it is found that the sharpness of the indication varies according to whether the distant transmitter lies fore-and-aft or athwart the ship. According to the invention, an auxiliary voltage is derived from an omni-directional aerial n and is used to correct this defect and to give an equally clear-cut indication for all points of the compass. As shown, signal voltage from the cross frames a, b, which are constantly rotated by a motor W through a shaft g, is fed through a reversing switch U to the fieldcoils d, e of a radiogoniometer. The searchcoil f, also mounted on the shaft g, feeds the resulting voltage through coils h, k to the receiver m. The auxiliary aerial n is connected through a switch o to a fixed coil q, which is variably coupled to a rotating coil v and applies a correcting voltage through the coil B (which is in series with the coil r) to the receiver m according to the direction of the distant transmitter. There is also a fixed coupling through the coils B, k. The other setting of the switch o applies a sense-determining voltage through the coils A, u to the receiver. The relative angular setting of the coils f and r may be adjusted.

[Also in Group XXIX] Vibrations are damped by the inherent slip in a hydrostatic coupling having no valves. Leakage of oil from recesses 15, 16 through holes 9, 10 into chambers 11, 12 gives the slip. The slip can be adjusted by using oil of a predetermined viscosity or by providing small apertures leading from the recesses 15, 16. The coupling comprises a casing 1, connected by bolts 2 to a prime mover, and a secondary part 3 carrying gear wheels 5 secured to the driven shaft 4. The gears 5 engage internal teeth on the casing 1 and, when the latter is rotated, tend to deliver oil from the recess 15 to the recess 16 (or vice versa). Plates 7, 8, however, seal off the recesses and the whole coupling rotates, driving the shaft 4.

Abstract: 1278597 Electric selective signalling MOLINS MACHINE CO Ltd 15 July 1969 [16 July 1968] 33877/68 Heading G4H A data-processing system for use with, e.g., cigarette manufacturing machines M comprises a testing device T associated with each machine, a slave transmitter and receiver S.T.R. associated with each testing device and a master transmitter and receiver M.T.R. connected to the slave units by a common bus C.B. Each of the slave units translates data from its associated testing device into digital form for transmission to the master transmitter over the bus C.B. The master transmitter is connected to a data processing machine C and is arranged to establish communication with the slave units in sequence and transmit control signals to each slave unit to cause them to transmit their translated data. The system also includes means for carrying random samples of the cigarettes to a measuring device C.M.E. Trays containing random samples from each machine are carried by a conveyer S.C. to the measuring equipment and the results may be used for comparison with the digital data. Each tray carries a coated magnetic pattern on its side for identification. The measuring equipment data may be transmitted to the data-processing machine C in the interval between digital transmission cycles and may be compared with the digital data for error detection purposes. Each slave unit has a digital address to which it responds by becoming ready to transmit data. The slave units may also be arranged to transmit their address before the data to ensure that the correct unit has responded. The system also provides an analogue link AL from the slave units which is passed through an A-D converter and thence to the data-processing device C. The analogue signals from, e.g. a beta-ray density checker are received simultaneously with the digital data from the slave units but in a different time sequence. The analogue data may for example be transmitted by the unit S.T.R.1 during the time that digital data is being transmitted by the units S.T.R.l-6, then S.T.R.2 transmits its analogue data during the time that units S.T.R.1-6 are transmitting digital data and so on. The dataprocessing machine is arranged to accumulate the total number of cigarettes produced by each machine and the total number rejected for every possible cause and to compute trends from the data received.

[Also in Divisions G1, G3 and H4] The degree of elongation e of a metal strip 1 (Fig. 6) during a rolling operation by work rolls 2 is measured by forcibly vibrating the strip in the direction of its thickness to generate a standing- wave vibration of the strip of prescribed wavelength 2L, and measuring the amplitude A of the standing wave. The half wavelength L is the spacing of support rollers 16, 16<SP>1</SP> (or roller pairs 6, 7 in the Fig. 4 embodiment), which is measured by a gauge giving an output voltage VL. Devices 8, which may be electromagnetic or comprise fluid ejectors, are actuated in turn to vibrate the strip. A sensor, which in Fig. 4 comprises a light source 13 for reflecting a beam off the strip surface into a differential pair of photo-electric detectors S1 S2, gives an output voltage VA representing the standing wave amplitude. A computing circuit determines (VA/VL)<SP>2</SP>, which is proportional to e, and gives an output signal which may be used to control crown wheels or other rolling apparatus to maintain flatness of the strip. Several sensors may be disposed across the strip width to detect buckling of the strip.
