IPC: H01L31/08
Filed: 1929-05-11
Abstract: 333,293. Prior, W., and Crisp, C. May 11,1929. Light-sensitive cells. - The electrodes of a selenium cell are wound on a cylinder or rod, the selenium being spread over the entire cylindrical surface and the cylinder being capable of rotation at any desired speed enabling the surface exposed to illumination to be constantly changed. The cell may comprise a conducting cylinder 3, Fig. 6, wound with an insulated wire 14, the insulation being removed and selenium 16 applied as shown; or may comprise a non-conducting cylinder 3, Fig. 3, wound bispirally with two insulated wires 1, 2, (or both wires may be uninsulated) the selenium 12 filling the interstices. If the cylinder 3, Fig. 3, is conducting, a layer of mica, 4 may be provided between the cylinder and the electrodes. Another form comprises a conducting cylinder wound with one insulated and one uninsulated wire. In all forms, contacts to the electrodes are led to metal plates 5, 7, Fig. 1, on the ends of the cylinder, from which current is collected by brushes.

IPC: D07B3/06
Filed: 1919-06-11
Abstract: 128,558. Blomqvist, K. R. June 20, 1918. [Convention date]. Machines for making.-In a machine for spinning wire rope &c., comprising rotary stranding- elements travelling round a rotary spinning- element of higher order, the stranding-elements, shown as comprising a core spool 45<1>, wire spools 17, a rotating spindie 13 carrying the wire spools, and a stationary mouthpiece 23, are carried by radial arms 4, 5 on the rotating spindle 3 of the rope-laying element of higher order, and the lower arms 5 are supported by rollers 6 running on a circular track 2. The spools 17 are mounted in forks on shafts 16 arranged in two circular series on the upper face of a hollow extension 14 on the spindle 13. Rotation of the spools 17 relatively to the spindles 13 is effected by means of gearwheels 18, on the lower ends of the shafts 16, intermeshing with each other and with a central gear-wheel 19 on a fixed shaft 13', which extends through the upper part of the spindle 13 and is attached to the arm 4. The spindles 13 are rotated by means of reversible bevel-gear 12, 11, 9, 7, from the rollers 6. The wires from the spools 17 are guided near the mouthpieces 23 through holes 21 in flanges on the spindles 13 and other holes in disks 22 on the spindles. The laying-element includes the spindle 3, a stationary mouthpiece 29, and a core spool 45. The spindle 3 is driven from the main shaft 42 by bevel gear 43, 44. The strands are led over tension wheels 24, 25 and through holes in a disk 26 on the spindle 3 to the mouthpiece 29. The rope passes over a feed-wheel 30, tension wheel 31, and guide-wheel 46 to a winding-drum 47; the feed-wheel 30 is driven from the shaft 42 through an intermediate shaft 39 and interchangeable gear 36, 34, 33.

Title: Magnetic testers
IPC: G01N27/84
Filed: 1974-04-03
Abstract: 1508771 Magnetic flaw detection BRITISH STEEL CORP 3 April 1975 [3 April 1974] 14808/74 Heading G1N A method for testing ferromagnetic strip material for inclusions involves applying to the strip a magnetic field generated independently of and at one side only of the strip and subjecting to the influences of the region so magnetized a suspension of ferromagnetic particles in a liquid carrier. A rigid sheet 4 of non-magnetic material supports a sheet 6 of tin plate under test. Disposed beneath the support sheet is an array of electromagnets (8), Fig. 2 (not shown), connected to a D.C. source. Mild steel bars (14) extend transversely of the rows of magnets to strap like poles together. A manifold 20 supplies the magnetic ink which is collected in a gulley 22 for recycling after passage over the test sheet.

Title: Holder for liquid make-up
IPC: A45D40/26
Filed: 1968-03-28
Abstract: 1,215,762. Portable containers; container closures; container and brush assemblies. EJECTORET S.A. 28 March, 1968 [5 April, 1967; 22 Aug., 1967; 15 March, 1968], No. 14914/68. Headings B8D, B8P and B8T. [Also in Division A4] A container comprises a neck and a brush mounted on a closure for the container, the brush being protected by a tube. The tube and brush are slidable relative to each other so that when the brush is removed from the container it projects from the tube. In one form a container 1, of metal or plastics and for, e.g. cosmetics, has a brush 23, mounted by means of its stem 19 on a button 25 in a closure 2, protected by a tube 18. The closure 2 can be unscrewed from a neck 7 of the container, inverted, and screwed back on to the neck by means of a thread 31, whereupon the neck 7 abuts the button 25 and causes a spring 28 to be compressed, so effecting the projection of the brush 23 from the tube 18. Reversing this operation allows the tube 18 to be spring returned to the position shown, protecting the brush 23 when it is pushed through a resilient sealing gland 12 and replaced in the container 1. The gland 12 wipes excess liquid from the tube when removing the brush and a sealing ring 33 prevents leakage through the tube 18 into the closure 2. In modifications, turning an end-knob (63), Fig. 5 (not shown), or a cylindrical easing (107), Fig. 10 (not shown), around the closure, acts through diametrically opposed lugs engaged in longitudinal slots (82 or 82a) and helicoidal grooves (83 or 83a), and causes the protecting tube to slide along the brush. In another modification, the protector tube (75), Fig. 13 (not shown), is fixed on a sleeve (117) which slides between shoulders (122, 125) in the closure, where it is retained in brush covering and uncovering positions.

Abstract: 797,405. Filters. BENDIX AVIATION CORPORATION. May 14, 1956 [June 22, 1955], No. 14967/66. Class 46. [Also in Group XXVIII] A filter casing 10 and 16, Fig. 1, having inlet 12 and outlet 14 is divided into two chambers 32 and 34 by plates 48 and 50 spaced from each other by U-shaped channels 58 and stiffening members 62. An edge filter 28 of the washer type is closed at its lower end by a spring retainer 40 and flange 46 and at its upper end by a ferrule 38. A spring 42 attached to the spring retainer 40 passes through the filter, ferrule 38, and holes in plates 48 and 50 and looks onto a pin 43 secured to the plate 48. The ferrule 38 also passes through the holes in the plates 48 and 50 and has slots 69, Fig. 4, which align with the pin 43 to allow satisfactory sealing between the plate 50 and the ferrule by a knife edge on the flange 64. To allow assembly of the filter element 28 the ferrule 38 is provided with a slot 72 in a lug 71 to receive the spring prior to assembly of the filter in the casing. A hole 74 communicates with the chamber between the plates 48 and 50 to allow drainage of the chamber. The flange 64 may be adapted to contain a sealing ring instead of the knife edge. Any number of filter elements may be assembled in the casing.

Title: Improvements relating to the reduction of interference in thermionic valve circuits
IPC: H03D7/18
Filed: 1932-05-26
Abstract: 403,709. Valve circuits for wireless reception. ELECTRIC & MUSICAL INDUSTRIES, Ltd., Hayes, Middlesex, and WILLANS, P. W., 18, Park Hill Road, Hampstead, London. May 26, 1932, No. 15010. [Class 40 (v).] In a wireless receiver a circuit tuned to an unwanted frequency is arranged in the common anode and control grid circuits of a valve. The circuit may be tuned by a condenser ganged to the tuning condenser and in a superheterodyne receiver may be employed in the intermediate frequency stages or to prevent second channel interference or to prevent interference due to harmonics generated by the oscillator, in which case the circuit may comprise a low pass filter. The Figure shows a superheterodyne receiver in which the circuit 36, 37 is resonant at the frequency of second channel interference and the circuit 16<1> 17<1> may be resonant at this frequency or at a frequency at which interference arises due to other causes. The circuit 16<1> 17<1> may be fixed tuned or be replaced by a low pass filter to remove harmonics of the intermediate frequency or interference due to harmonics from the oscillator. The Provisional Specification describes the application to a receiver operating over two wave-bands to prevent the shorter wave-band signals from breaking through and producing interference on the longer wave band by means of a circuit thrown into and out of operation by the wave range switch. The Provisional Specification also describes the application of the invention to a beat frequency oscillator for producing audio frequencies in which interference due to oscillator harmonics or harmonics produced by the non-linearity of the detector is avoided. According to the Provisional Specification the feed back may take place to the grid circuit of a preceding valve instead of between the anode and grid circuits of the same valve.
