Title: Improvements in or relating to impellers for centrifugal pumps, and the improved centrifugal pumps resulting therefrom
IPC: F04D9/00
Filed: 1944-07-07
Abstract: 583,928. Centrifugal pumps and compressors. PESCO PRODUCTS CO. July 7, 1944, No. 13017. Convention date, May 29, 1943. [Class 110 (i)] In an impeller for a centrifugal pump or compressor, the cross-sections of the fluid passages are of such shape as to induce and maintain circulation substantially in a plane at right angles to a radial line extending from the axis of the passage at any point to the axis of the impeller. The passages are open on one side and co-operate with an adjacent stationary surface to maintain the circulation. The impeller 14 of a fuel pump comprises spirally extending vanes 18 between which are channels 19 having the cross-sectional shape shown in Fig. 5. The impeller rotates in.close proximity to a surface 22, which exerts a frictional drag upon the liquid in the channels, causing rotation in the direction shown. This is stated to increase the efficiency of the pump. Impingement of fuel upon the sharp edges 27 of the vanes on entering the impeller eye tends to release occluded vapour which rises upwardly through the inlet mouth 11 and escapes through a side screen 49. A propeller-like beater 12 further assists in the release of vapour. Rotation of liquid entering the impeller eye is prevented by straightener guides 46.

Title: Improvements relating to the drying by induction heating of colours, lacquers, and the like on metal bodies
IPC: H05B6/10
Filed: 1951-06-01
Abstract: 705,294. Drying in electromagnetic fields. DAIMLER-BENZ AKT.-GES. June 1, 1951 [June 1, 1950], No. 13098/51. Class 34(2) [Also in Group XI] Lacquers or artificial resin layers on the metal skin of bodies for vehicles or on other hollow bodies of large surface and irregular form are dried by inducing eddy currents in said bodies by induction coils of electro magnets which are placed within or outside the bodies. The windings or electromagnets are divided into parts movable in relation to each other and all the parts are in direct conducting connection with the A.C. source. In Fig. 1, the body 10 is run on a wheeled carriage 11 into an induction coil 12 shaped to surround the body and carriage and divided to have hinged end coils 16, 17 tapering to surround closely the tapering ends of the body: The coils may be wound on thin tank containing a liquid dielectric, the tank pasteboard supports, which closely . surround the body and prevent heat loss and radiation therefrom so that the current to most turns of the coil can be switched off before the body is dry. In Fig. 3, electromagnets 20 with adjustable poles 22 to '24 shaped .to conform to the arched outer body surface are energized by a winding 21 on a laminated iron core 25. Alterriatively, substantial flat spiral induction coils are placed near the outer surface of the body, and short solenoids of a cross section conforming to a window are inserted in the window openings. In Fig. 5, the body is heated by running thereinto induction coils 30, 31 through the space for the windscreen and through that for the rear luggage boot. These coils are mounted on formers and current flows through both in the same direction so that the total induced current flows in the same direction in the metal skin. Alternatively a car body with no floor is lowered on to a vertical coil shaped to the inner body surface and is also heated by an induction coil about its outer surface. In a production line in Fig. 7, the bodies 10 are run on rails 13 to a turntable 40, whence they are introduced one into each 'compartment 39 on a roundabout structure 37. A horizontal coil 30 on the inner wall of the radial compartment thus projects into the body through its windscreen aperture. The hinged side walls 38 carrying solenoids for the window are then closed, and finally an outer wall 45 carrying a coil 31 is run in on an undercarriage to close the compartment, said coil 31 entering the body through the boot opening. On locking the walls, the current is switched on and the turntable 37 containing in the centre at 47 a suction plant and the electrical gear, is rotated at such speed, that when a complete rotation has been made, the other compartments having also been filled, the body is dry and is moved back to the turntable 40 and the production line.

Abstract: 935,221. Electric selective signalling systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 14, 1961 [April 14, 1960], No. 13459/61. Class 40 (1). [Also in Group XL(c)] A transistorized de-coding circuit employs a plurality of " multiple-output inhibit " gating circuits. Each of these circuits has a first plurality of n input leads 1, 2 ... n, Fig. 1, which, in the presence of signals on everyone of a second plurality of N control input leads (shown with a heavy arrow head). I, II ... N, are respectively connected to n output leads 1, 2 ... n (11, 12, 13). In the absence of signals on all the control input leads any other input is inhibited, and in the presence of signals on every control input lead but in the absence of a signal on any one of the other input leads a signal is produced on an output lead 14. Two circuits operating in this manner are described: Fig. 2, using PNP transistors, and Fig. 3 (not shown), using NPN transistors. In Fig. 2, where the referencing follows that of Fig. 1, transistors 35 ... 37 are biased sufficiently negatively so that they remain conducting even in the presence of signals on leads 1, 2 ... n. Thus none of transistors 31, 32 ... 33 can conduct unless all of transistors 35 ... 37 are rendered non-conducting by inputs I, II : .. N Transistor 34 has an intermediate bias so that if all of transistors 35 ... 37 are rendered non- conducting and none of transistors 31, 32 ... 33 are rendered conductive then it conducts. In the actual decoder, Fig. 4, five binary inputs A, B, C, D and E are decoded to give a marking on one of 32 outputs. The first three bits A, B and C are decoded by circuits 21, 22, 23, 24 and these outputs, with bits D and E are decoded by circuits 25, 26, 27 and 28.

Abstract: 1499593 Measuring voltage CROWCON (INSTRUMENTS) Ltd 29 March 1976 [3 April 1975] 13693/75 Heading G1U In monitoring a parameter (e.g. gas concentration) at a remote location a unit is provided at the location which controls the frequency of an oscillator therein, the oscillator providing the drive signal for a 'switched mode' regulator whose stabilized output powers the unit, the unit being connected to a central station over power supply cable, and the ripple frequency thereon is measured at that station to determine the parameter. The regulator R supplies a stabilized voltage to the sensor bridge B whose output voltage controls the frequency of an oscillator VCO which provides a triangular waveform to a regulator control circuit. The stabilized voltage is compared with a Zener diode reference voltage in the control, and the difference is compared to the triangular waveform to provide a pulse-train whose mark/space ratio controls the regulator output voltage. Due to the switching action of the regulator, a ripple frequency appears on the unregulated supply from the cable link, the frequency being representative of the bridge output. At the central station, Fig. 3 (not shown), this frequency is filtered out and measured.

[Also in Group XL(b)]  In a method of producing a record indicating the correlation between two signals, each signal is recorded as a constant width track on a transparent recording medium on the same time scale with the signal amplitude represented by the transverse position of the central portion of the track, the recording media are superimposed in contact with coincidence of their time scales and are exposed to a constant intensity light source, one of the media is moved lengthwise relative to the other, and the amount of light passing through the media is registered. The invention is described as applied to the analysis of the signals received at each of a spread of geophones, Fig. 3, by subterranean refractions and reflections of a varying-frequency wave, Fig. 2, produced in the earth by means of the mechanical vibrator described in Specification 768,845. The transmitted and received waves are recorded in the above form either directly or after transcription via magnetic tape. Record 28, Fig. 2, is arranged to contain one or more of tracks 26 and is placed on movable record 36, Figs. 3 and 4, between extended fluorescent light source 40 and elongated photo-cell 44 the output of which is fed to recorder 46 which runs in synchronism with the motion of record 36.
