Title: Improvements in or relating to rotary vane pumps
IPC: F04C15/00
Filed: 1965-08-05
Abstract: 1,107,103. Rotary vane pumps. H. TEVES, E.A. TEVES AND M. TAUSEND [trading as ALFRED TEVES MASCHINEN-UND ARMATUREN FABRIK KOMM. GES.]. Aug. 5, 1965 [Nov. 5, 1964], No.33567/65. Heading F1F. A rotary vane pump that may be reversibly driven whilst maintaining the same direction of pump delivery, comprises a cam-plate 12, Fig. 1, mounted via an anti-friction bearing 13 in a bearing ring 14 and fitted with a stop 28 engageable with one or other of two abutments 29 at the ends of an arcuate recess 32 in the bearing ring 14 extending over about 90‹. Pump discharge pressure is supplied to beneath spring-loaded vanes 10 slidably mounted in radial axially-extending slots 33 in the rotor 7' and to an axial bore 26, Fig. 2 in the rotor shaft 7 in which a spring-loaded piston 25 constituting a hydraulic accumulator is mounted. On clockwise rotation of the rotor 7', hydraulic pressure in the slots 33 causes friction between the ends of the vanes 10 and the cam surface of the cam-plate 12 to rotate the latter until the stop 28 engages the left-hand abutment, the pump then operates to such in liquid through the intake 2 and orifices 20, 21 and to discharge through outlet channels 22, 23 to the pump discharge 6. On reversal of rotation of the rotor 7', the accumulator augments the pressure in the slots 33 to increase friction between the vane ends and the cam surface so that the cam-plate 12 rotates anti-clockwise in the direction of the arrow until the stop 28 abuts the right-hand abutment 29, with the liquid still being sucked in through the intake 2 and discharged through the discharge 6. The diametral disposition of the working chambers 17, 18 provides hydraulic balance of the pump. A non- return valve 31 is provided in a channel connecting the slots 33 with the discharge 6 to ensure that the vanes 10 are in frictional contact with the cam surface during pump reversal. Excess lubricating oil from the main bearing 34 returns to the intake chamber through channels 15, 15'.

Title: Improvements in signal synchronizer
IPC: G11B20/20
Filed: 1956-11-05
Abstract: 809,849. Magnetic recording and reproducing apparatus. SPERRY RAND CORPORATION. Nov. 5, 1956 [Nov. 16, 1955], No. 33724/56. Classes 40 (1) and 40 (2). In a magnetic tape record apparatus employing a plurality of longitudinal tracks for simultaneous reproduction, variation of synchronism between the tracks owing to skewing of the tape is compensated by deriving a difference signal from identical pulsed tracks at the outside edges of the tape, and utilizing said difference signal to apply time delays to the signal channels to correct the synchronization errors between said channels. Fig. 2 illustrates an embodiment of the invention in which numerals 18 to 23, inclusive, indicate a number of transducer heads in contact with a plurality of tracks on a tape 10. The outer heads 18, 23 carry identical pulse signals which are passed through inhibition gates G1, G3 and G2, G4, respectively, of a kind well known in the art, to flip-flop circuits FF-1 or FF-2, according to which input signal is leading, the output signal having a length corresponding to the time difference of the inputs. The signals from the flip-flops FF-1 or FF-2 are fed through rectifiers D1 or D2 to series resistances and capacitors R1, C1 or R2, C2 respectively, and the developed voltages applied to series-connected coils wound on magnetostrictive time delay elements in the circuits of the transducer heads 19 to 22, inclusive, carrying the signal channels. The number of turns on each of the time delay elements are progressively increased in opposite directions so that the greater time-delay required on the channels towards the edge of a skewing tape is proportionately applied.

Abstract: 471,887. Gas turbine plant. JENDRASSIK, G. Dec. 9, 1935, No. 34106. Convention date, April 1. [Class 110 (iii)] The gas for a gas turbine plant is compressed by a multi-stage compressor to not more than eight times its initial pressure following which it is heated to at least 70 per cent of the highest temperature of the working cycle in a periodically operating heat exchange device heated by exhaust gases whereupon it is passed to the turbine in which fuel is burnt upon admission and/or during expansion. The Figure shows a turbine 1 and a triple section heat-exchanger 24<1>. Air is supplied by a rotary compressor to a pipe 23. from which it passes under the control of valves 26<1>, 31<1> through one of the sections of the heat-storer to the inlet pipe 25 of the turbine. The exhaust of the turbine passes through the other sections of the heatstorer to pipe 30 and to atmosphere. Periodically the valves, which are driven by an electric motor, are actuated so that the compressed air is passed to a section which has just been heated, and exhaust gas is diverted to the previously used section. Fuel is supplied to intermediate stages of the turbine by a pipe 11 and may be also at the point of admission. Additional air may be admitted from a pipe 12. In a modification, the exhaust gases are returned to the compressor and extra air is introduced.
