Title: Improved process of and apparatus for the manufacture of abrasive articles
IPC: B24D11/00
Filed: 1932-02-01
Abstract: 396,385. Emery and sand cloth &c. BEHR-MANNING CORPORATION, Troy, New York, U.S.A. Feb. 1, 1932, No. 2971. Convention date, Nov. 20, 1931. [Class 60.] In the manufacture of sand paper and like abrasive material, the abrasive particles are propelled on to the backing material by an electrical field. The abrasive particles are disposed in a hopper 10 and fed therefrom by a roller 12 on to a travelling conveyer 13 in a layer of desired density. The backing material 14 is coated at 15 with adhesive and is passed in promimity and parallel to the conveyer 13, coming into an electrical field produced by an electrode 17, and if desired an earthed electrode 13<1> contacting with the conveyer ; the field causes the abrasive particles to be lifted from the conveyer and deposited on the backing. In a modification, the hopper has an upturned mouth from which the abrasive particles are attracted by a charged electrode from which they are moved to the adhesive coated backing, passing beneath the electrode, by the electrical field between the electrode and another situated below the backing.

Title: Improvements in or relating to electrical oscillators
Inventor: VARRALL JOHN EUSTON
IPC: H03B21/02
Filed: 1967-01-19
Abstract: 1,141,952. Frequency generating circuits. AIRMEC Ltd. 19 Jan., 1968 [19 Jan., 1967], No. 2979/67. Heading H3F. A frequency generating arrangement comprises an oscillator providing a first frequency, indicator means providing a measure of that frequency, and frequency-dividing means reducing the frequency to an accurate submultiple from which an output signal is produced, whereby the indicator means can be used to determine the output frequency without a full cycle of said output frequency having to be completed. A driving oscillator 10, preferably of sine wave output, produces a direct output on terminal 18 and also drives the first in a series chain of frequency dividers 12. Each of the dividers 12 comprises a cyclic counter type circuit and produces a second output signal whose amplitude at any given instant is proportional to the number of cycles counted since the preceding zero count. These second outputs from counters 12 are fed to an adding circuit 13 which generates a staircase waveform each step of which represents one count in the frequency dividers. Adder 13 feeds a phase inverter 14 producing an inverted staircase waveform which with that from adder 13 is fed to an electronic switch 15 which operates in synchronism with the frequency dividers to select alternate cycles of the two staircase waveform inputs to produce an essentially triangular waveform. The steps of this are smoothed and the waveform converted to sinusoidal form in a shaping circuit 16 which also renders the peak amplitude independent of frequency. Attenuator 17 enables the final output amplitude to be varied. The Specification also describes the use of the arrangement in measuring phase-shift in a circuit under test (Fig. 2, not shown).

Filed: 1943-02-25
Abstract: 567,881. Torsion testing; pressure gauges. LAYCOCK ENGINEERING CO., Ltd., and CHARLESWORTH, T. R. Feb. 25, 1943, No. 3079. [Class 106 (ii)] A specimen 79 being tested for torsion is subjected at its ends to equal and opposite couples applied through a force acting between a lever secured to one end of the specimen and another lever forming part of a system of levers secured to the other end. A cylindrical bar 14 supports a headstook bracket 15 with an arm 18 and a lever 34 pivotally connected to another lever 36 secured to a keying bracket 28. The specimen. 79 is secured between grips 20, 29 carried respectively by an arm 19 rotatably mounted in the bracket 15 and by the bracket 28. The bracket 28 can be adjusted to suit the length of the specimen by a screw 32 rotated by a handle 33, as shown in Fig. 1. In use, a hydraulic ram (not shown) forces arms 18, 19 apart, applying equal and opposite couples to the ends of the specimen without applying any stress to the supports of the machine. The hydraulic ram is operated by fluid from a reciprocating pump 45, Fig. 6, when a handle 66 is moved to the right to depress a plunger 55 whereby a spring 49 becomes operative to hold a roller 42, connected to the piston of the pump, against a motor-driven eccentric 41. With the handle 66 in central position, the spring 49 is inoperative and no further fluid is supplied to the hydraulic ram. Movement of the handle 66 to the left, through a rod 58 operates a valve to release the pressure. A pressure gauge 67 indicates the pressure and/or the stress applied. A point 71 may be set manually to indicate the desired pressure, while a pin 73 on the usual needle 68 may move a maximum-indicating pointer 72. The pointers 71, 72 may be secured from interference by a padlock 75. A pointer carried by the headstock 15 may indicate against a sector-shaped scale, Fig. 3 (not shown), carried by the arm 19, the strain impressed on the specimen.

Title: Improvements in valves
Inventor: SMITH CHARLES PHILIP
IPC: F15C1/16
Filed: 1969-01-20
Abstract: 1,249,712. Fluid regulation. H.M. HOBSON Ltd. April 17, 1970 [Jan. 20, 1969], No.3118/69. Heading G3H. An assembly for providing a constant flow-rate irrespective of variations in the supply pressure above a predetermined value of the supply pressure, comprises a vortex valve V, a spool valve 15, and a restrictor R 1 . With the pressure P of the supply, not shown, being below the predetermined value, the differential created across the restrictor R 1  is insufficient to move spool 15 against the action of a spring 5 and so all flow from the source takes place along duct portions 30 and 10 with the supply to the vortex valve being at a pressure Ps and the outflow from said valve being at a corresponding pressure Po. Upon the supply pressure exceeding the predetermined value, the differential created across restrictor R 1  causes spool 15 to move against spring 5 thereby opening a passageway 16 which communicates with the duct 30 and with the vortex valve control passage 14. Accordingly, the supply Ps to the vortex valve is modified by the controlling pressure admitted through duct 14 with the result that the pressure of the outflow from the vortex valve is maintained substantially constant. Figs. 3 and 4 (not shown), depict modifications of the above assembly.

Title: Optical scanning system
Inventor: LOY F R
IPC: H04N3/08
Filed: 1976-01-28
Abstract: The present invention relates to a device for optico-mechanical scanning of a field of view in two perpendicular directions, which can be produced solely by means of mirrors and is therefore usable whatever the wavelength of the radiation. The line scanning is carried out by means of a drum rotating about a fixed axis provided with plane reflecting faces and with a fixed optic ensuring the detector's image conveying at a point of the said axis. The frame scanning is ensured by means of a flat mirror which can move about an axis parallel to the direction of line scanning. A so-called field mirror ensures that the beam leaving the objective and the frame scanning device is turned back towards the line scanning system and the detector. It permits exact focusing of the field with the line surface analysed. The device can moreover include a system for direct display of the image of the field using all or part of the scanning optic and a light-emitting diode controlled by the video signal. Application: television. <IMAGE>

Abstract: 941,172. Centrifugal pumps. M. AMIRAULT, and P. DESTOUMIEUX. Jan. 30, 1962 [June 17, 1961], No. 3417/62. Heading F1C. A centrifugal pump impeller comprises a relatively thin disc formed with a central circular mounting aperture and arcuate slots around the aperture, the annular flange thus extending beyond the arcuate slots being corrugated to provide alternately protruding and recessed sectors and thus forming vanes on both faces of the impeller and the sectors which protrude on the inlet face of the impeller extending radially beyond the respective arcuate slots. The centrifugal pump impeller shown in Figs. 1 and 2 comprises a disc 1 pressed from a thin sheet metal blank to form sectors a, b, c projecting towards the front or inlet side of the impeller and sectors d, e, f projecting towards the rear side. The sectors form six radially disposed impeller vanes. The liquid has direct access to the sectors d, e, f, but enters the sectors a, b, c through arcuate apertures g. The impeller may alternatively be moulded from metal, natural or synthetic rubber or plastics material (which may be in sheet form). Less or more than six sectors may be provided. The sectors need not have the same shape and capacity as one another. The front face of the impeller and the adjacent surface of the casing 4 may be of conical form. A cylindrical shroud may project from one or both faces of the impeller. As shown in Fig. 8, the sectors may be curved or otherwise non-radial, and the aperture g may increase in width. The circumferential edges of those sectors which project towards the rear side of the impeller may be scalloped to facilitate the outflow of liquid.
