Title: Improvements in electrolytic condensers
IPC: H01G9/048
Filed: 1938-04-22
Abstract: 503,370. Electrolytic condensers. MALLORY PATENTS HOLDING CO., Ltd. April 22, 1938, No. 12170. Convention date, Sept. 11, 1937. [Class 37] An electrode comprises one or more layers of fabric &c. having an open-mesh or porous structure upon which a filmforming metal has been deposited by spraying, the mesh or porosity of the fabric and the sprayed deposit being such that the layer is light-pervious. In the simplest form a single layer of sprayed fabric 90, Fig. 16, is used. To ensure electrical conductivity the edges may have a reinforcement of metal shown as either enclosing the edge 88, or stitched to one side 89. The metal reinforcing strip or strips may extend along the sprayed fabric otherwise than along the edge and may be also in the form of a number of angularly placed transverse strips or may form a fullwidth metallic backing, in some cases perforated. Such strips are bonded to the fabric by the operation of spraying which penetrates through the fabric. In modifications two layers of fabric are used, and in the electrodes 42, 43 of the example, Fig. 8, two longitudinal metal strips are enclosed between the layers, the whole bonded by spraying. Gauze separators 46, 47 are shown, interleaving the electrodes. The condensers may be made in flat form, that shown in Fig. 12 employing two electrodes 69, 70 of sprayed fabric, separated from three sheet aluminium electrodes 71, 72, 73 by electrolyte-holding spacers. Terminal tabs for sprayed electrodes may take the form of strips of foil bonded by the spraying, or of metal strips either riveted as 45, Fig. 8, or folded over the edge and punched through. The longitudinal conductors, instead of being in strip form may be of wire, held between sprayed fabric layers, and extending from one end to form terminal tabs. The fabric may take the form of an open mesh, Fig. 20, with wires 99 replacing certain of the threads and these wires may be rolled to flatten them. Alternatively a fabric comprising a series of longitudinal threads including some of metal may form the base upon which the metal is sprayed.

Title: Nonthermionic electron gun assembly
IPC: H01J37/077
Filed: 1966-03-21
Abstract: 1,132,536. Electron guns. GENERAL ELECTRIC CO. 21 March, 1966 [28 May, 1965], No. 12282/66. Heading H1D. In a non-thermionic electron gun assembly comprising a hollow cathode 7 which has a single aperture in one end wall and which is surrounded by and insulated from electrically conductive shield 9, an auxiliary electrode 22 is provided externally adjacent the cathode aperture and a potential is applied to this auxiliary electrode such that, when a high negative potential is applied between the cathode and shield to produce a plasma within the hollow cathode, focusing of an electron beam derived from the plasma and emerging from the cathode aperture is facilitated. The auxiliary electrode, which is adjustably maintained at a potential close to that of the cathode, alters the shape of the electric field near the cathode aperture and increases the range of electron beam intensity over which the desired beam mode, i.e. convergent and then divergent as opposed to a parallel beam, is obtained. The auxiliary electrode may consist of a disc with an aperture aligned with that of the cathode. As shown, in a preferred embodiment auxiliary electrode 22 completely surrounds and is the same shape as the cathode and its aperture is aligned with that of the cathode. The cathode 7 is supported by stem 16 which may be hollow to permit circulation of a coolant fluid and to which is applied the high negative potential, the shield 9 being at earth. Stem 34, which supports electrode 22 is concentric with stem 16 and both are affixed to insulator 17, which forms part of a chamber that houses the beam source and provides the low pressure gaseous environment in which the non-thermionic beam is produced. Two separate means of providing the adjustable cathode-electrode potential are shown; one means uses only the variable resistances 40, 41 and the other means uses only the batteries 42, 43 with respective variable resistances 44, 45. Variation of the cathode-electrode potential affects the focus and magnitude of the electron beam. Numerical values of electrode dimensions, operating voltages and gas pressure are given. The source may be used in irradiation or welding apparatus.

Title: Improvements in or relating to current and voltage indicators for direct current circuits
IPC: G01R17/16
Filed: 1940-07-30
Abstract: 543,061. Current and voltage measurements. SHERIDAN, V. A. July 30, 1940, No. 12335. [Class 37] A valve voltmeter is provided with a second multi-grid valve to give increased stability when measuring low voltages or when operating from a mains power supply and also to prevent damage to the instrument if the voltage to be measured greatly exceeds the measuring range. The D.C. voltage to be measured at terminals 1, 2 is applied to the grid of a triode 4, the grid leak 3 of which is connected to a point having a potential negative to the cathode. A hexode valve 11 has its screen grid connected to a point on a resistance 9 of positive potential relative to the cathode, and its injector grid connected to the grid of the valve 4. The anode current of the valve 11 is equal to that of the valve 4 when no voltage is applied to its grid. A meter 8 connected between the anodes indicates zero under these conditions. Variations of anode potential affect both valves equally and do not affect the reading. The application of an excessive voltage biases the valve 4 beyond its cut off voltage and simultaneously the anode current of the hexode is reduced to zero owing to the negative bias applied to the injector grid, the instrument 8 therefore reading zero. Damage to the meter 8 when voltage is applied in excess of its maximum rating is thus prevented. The valves 4, 11 should have the same characteristics and may have a common envelope and a common cathode. Overvoltage may be indicated by separate means such as a " magic eye" cathode ray indicator of a relay connected in one of the anode circuits and controlling an indicating lamp.

A deburring tool comprises a cylindrical body 10 having a transverse longitudinally extending slot 12 forming two integral deflectable arms 13 extending from the body 10. Adjacent, but spaced longitudinally from the free end of each arm is a cutting portion 14 which is provided with cutting edges 16 spaced on each side of the cutting portion 14. A collar slidably mounted on the support arms 13 is securable thereto by means of a set screw so that the radial flexibility and stiffness of the arms will depend on the longitudinal position of the collar 19 on the arms 13. In operation the tool end 30 is inserted into a hole in a workpiece and is rotated by driving means, axial pressure effects deburring and subsequent inward deflection of the arms to permit the tool cutters to pass through the hole. Withdrawal of the tool effects deburring of the other end of the hole followed by inward radial deflection of the arms 13 to permit the withdrawal of the tool from the workpiece. In alternative embodiments the cutting portion may be on one arm only and there may be two axially spaced cutting portions on each of the arms.
