Abstract: 776,635. Centrifugal pumps. FABIG, G. Nov. 7, 1955 [Nov. 24, 1954], No. 31794/55. Class 110 (1). A self-priming centrifugal pump comprises a casing in two halves and provided with suction and outlet openings, a lateral annular passage for liquid provided only in the suction-side casing half, a receiving space in the pressureside casing half which extends only over a fraction of the periphery and is arranged substantially symmetrically with respect to the outlet opening into which it runs, and inclined or helically twisted impeller blades arranged with the edges of their front surfaces which are adjacent the receiving space trailing, relative to the opposite edges, with respect to the direction of rotation of the impeller. The suction side casing half 1, Fig. 1, has a lateral annular working passage 3 which, starting adjacent the suction opening 2, gradually increases in crosssection in the direction of rotation and finally decreases, the last part of the passage being brought closer to the axis of the pump in spiral fashion. The pressure side casing half 5, Fig. 6, has a receiving space 9 having its greatest depth in the region of a discharge opening 6 and gradually decreasing in width towards each end. A further discharge opening 7 is provided. The impeller comprises radial blades, each blade having a wedge-shaped cross-section, Fig. 12, with the front and rear surfaces bounded by a concave and a convex arc respectively. The edge 11 of the front surface trails with respect to the direction of rotation. A triangular pocket 12 is provided adjacent the casing half 1. The rear wall 13 of the pocket 12 is sloped off so that in the region of the discharge opening 6 each blade has the cross-section shown shaded in Fig. 12. During priming, the spaces between the impeller blades are filled with liquid through an auxiliary opening 8. The liquid and air entering through the suction opening 2 passes partly into the spaces between the blades and partly into the pockets 12. The liquid is thrown outwards by centrifugal force, to augment the ring of liquid in the passage 3, and the air is expelled through the discharge opening 7 by displacement effect. On completion of priming, the liquid is discharged partly by displacement effect through opening 7 but mainly by centrifugal effect through opening 6. The liquid entering the pockets 12 forms a cushion which tends to neutralize the end thrust of the impeller.

Title: Improvements relating to electric relays
IPC: H01H50/64
Filed: 1932-11-18
Abstract: 410,516. Electromagnetic relays. PETER, L. H., MAcGREGOR, R. M., and WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London. Nov. 18, 1932, No. 32702. [Class 38 (v).] An electric relay of the kind having a movable element directly coupled to contacts adapted when the relay is energized or de-energized to be opened or closed and included in a circuit or circuits to be controlled is provided with a device for automatically arresting or retarding the movement of the element at or during its approach to a desired position of rest, the device being arranged to be electrically operated or controlled in such a manner as to render the arresting or controlling action ineffective when the element is ultimately at rest in the desired position. As shown in Fig. 1 a permanent braking magnet 16 is provided, between the poles of which is moved a projecting portion 15 of a braking disc or damping vane 14 as the relay approaches its neutral position ; the eddy current braking effect thus slowing down the movable element of the relay when approaching this position. The permanent magnet 16 may be replaced by an electromagnet, the circuit of which is arranged in series with contacts controlled by the relay and with contacts controlled by a switch operated by cam formations on a braking disc which opens the electromagnet circuit as the disc moves towards its mid-position (Fig. 4, not shown). In this case the electromagnet is provided with a copper ring for preventing the collapse of the flux until the braking action has taken place. The braking may take place by magnetic attraction in which case appropriate portions of the braking disc carry plates of magnetic material. A further modification (Fig. 3, not shown) employs frictional braking, the braking member being controlled in its action by an electromagnet, the circuit of which is completed at contacts controlled by the relay. A development of this form shown in Fig. 5 has a detent 31 which by engaging notches 29, 30 in the locking plate 28 automatically arrests the movement of this plate as the relay reaches one or other of its energized positions. The detent is, however, automatically removed as the relay contacts close by the completion of the circuit of an electromagnet 36.

Title: Process and device for improving the treatment of schappe bands of viscose artificial silk during its progress through washing, sulphur-removing, bleaching, reviving and dyeing baths and the like
IPC: D01D10/04
Filed: 1935-11-26
Abstract: <PICT:0453682/IV/1> In a process for treating schappe bands of viscose artificial silk in washing, sulphur-removing, bleaching, reviving, dyeing or similar baths, the band during its progress through the baths in a horizontal plane has imparted thereto a tensioning and relaxing movement within the liquid whereby the fibres are opened out to the treating liquid.  The band 5 is conveyed into each bath 2 by a pair of feed rollers 3 which also express surplus treating liquid therefrom.  It is guided through the bath by rollers 4.  The device for imparting the additional movement to the band may be a bar 6 arranged under the band and swingable about an axis parallel to itself and above the band.  The upper surface of the bar 6 is higher in the bath than the lower surfaces of rollers 4.  The band carries the bar 6 along with it during part of its movement until the recovery forces overcome the frictional forces when the bar 6 swings back again.  In a modification, the bar may be vertically reciprocated by means external to the bath, or the pairs of rollers at each end of the bath may be rotated at periodically alternating speeds which are out of phase so that the band undergoes a periodic slackening and tautening.

Abstract: 941,727. Tunnel diode oscillator circuits; frequency modulation discriminators. SONY CORPORATION. Sept. 23, 1960 [Sept. 25, 1959; Oct. 12, 1959], No. 32838/60. Headings H3A, H3R and H3T. A tunnel diode oscillator B is injection locked in frequency by a received frequency modulated wave or oscillator A, and since the amplified resultant FM wave from the oscillator B is free of any amplitude modulation and differs in phase relative to the FM input in accordance with the instantaneous frequency deviation, the latter two waves, applied to a phase detector 14-16,produce a demodulated FM signal. The latter may be used to augment or decrease the tunnel diode bias, to increase or decrease the frequency swing following up ability of the oscillator when just failing to follow in frequency and thereby increase the detector sensitivity or the bandwidth it responds to with linearity. The oscillator B may also be tuned to a submultiple of the incoming frequency and the tuning capacity 10 may be dispensed with. Capacitors instead of transformers may couple the circuits.
