Filed: 1966-08-16
Abstract: <PICT:1097358/C6-C7/1> In a method for the electrolytic surface treatment of prismatic parts having in transverse cross-section n long sides of substantially equal length, said prismatic parts are supported within a coiled polygonal spring which is connected to a source of electrical supply having a horizontal axis, the spring having N sides where N > n and the spring is rotated about its own axis or about a line parallel thereto, such that the prism rotates within the spring and contacts each wall of the spring in turn, at least that part of the spring which contains the prism to be treated being immersed in an electrolytic bath.  In the form shown a plurality of springs are positioned between flanges 20, 22 fitted upon an axle 24.  The drum 18 thus formed is mounted with the axle horizontal and may be rotated about said axle by means of electric motor (16) Fig. 1 (not shown) within bath (10).

Title: Method of making titanium capacitors
IPC: H01G9/04
Filed: 1962-09-27
Abstract: In a method of producing titanium anode capacitors metal titanium is immersed in an acid to which the titanium is corrosion resistent in order to remove impurities and form a thin oxide film thereon, and is then anodised in a molten electrolyte consisting essentially of a mixture of the nitrates or nitrites of an alkali metal and the nitrates of an alkaline earth metal.  A solid electrolytic capacitor may be fabricated by coating this anodized electrode with a manganese dioxide semi-conductor layer, the manganese dioxide being formed by the pyrolytic decomposition of manganese nitrate, and thereafter applying a graphite layer. Finally a counter electrode is applied by vapour depositing a gold or aluminium film on the graphite or applying a silver paste thereto.  The titanium anode may be a foil, wire or rod and may be fabricated by sintering titanium powder of relatively large grain size.  Details of the sintering process are given in the Specification. Suitable solutions for carrying out the pretreatment of the sintered titanium rods in order to remove impurities and to coat them with a uniform thin oxide layer include acetic, chromic or nitric acids, the forming electrolyte for anodizing the treated electrode may consist of a molten mixture of potassium or sodium nitrate and calcium or strontium nitrate, or a molten mixture of sodium nitrite and calcium nitrate.  To produce a suitable film the forming conditions, which are determined empirically, are critical.  One set of suitable conditions is: temperature 32 DEG C., voltage 20 20 minutes.

Title: Control means for free piston or semi-free-piston engines
IPC: F02B71/06
Filed: 1958-11-19
Abstract: 853,183. Rotary distributers; control of several motors. SOC. D'ETUDES ET DE PARTICIPATATIONS EAU, GAZ, ELECTRICITE, ENERGIE S.A. Nov. 19, 1958 [Dec. 3, 1957], No. 37206/58. Classes 38 (3) and 38 (5). [Also in Group XXVII] A rotary distributer for controlling solenoid-operated valves of a free piston compressor or gas generator installation (see also Group XXVII) comprises angularly movable contacts (one only 21b 2  being shown) which are controlled by electric motors 48. Each of the annular supports (21c a  only shown) of the five angularly movable contacts is connected to an electric motor 48 2  through the medium of a toothed wheel 49 2  meshing with a toothed crown of the support 21c 2 . As particularly described the contacts are moved into the desired positions in accordance with the position of switches 58 controlled by the pressures in a free piston gas generator power plant. Each motor 48 is connected mechanically to a sliding contact 55 corresponding to it so that when the motor is under voltage is moves by its rotation its sliding contact around the circular resistance 54. In Fig. 8 the circular resistance as shown in the form of a cylinder surrounded by six rings 56 2  each of which comprises one of the sliding contacts 55. As long as the subdivision of the electrical potential by the series resistances 53 is the same as the subdivision of the electrical resistance 54 by the sliding contacts 55 there is no electric current in the communication lines in which the motors 48 are connected. If one of the gas generators is stopped the corresponding resistance 53 is short circuited and the total electrical potential is divided by the other resistances 53 into five parts. Consequently the motors 48 are put under voltage and move simultaneously the sliding contacts 55 and the contacts of the row of which 21b 2  forms a part until the sliding contacts ensure a subdivision of the electrical resistance 54 into five equal parts.

IPC: B23K9/067
Filed: 1958-11-19
Abstract: 850,428. Welding by fusion. COMMISSARIAT A L'ENERGIE ATOMIQUE. Nov. 19, 1958 [Nov. 21, 1957], No. 37261/58. Class 83 (4). In a method of arc seam welding members in a vacuum, the gap between the members and the welding-electrode is ionized to enable the arc to be started or re-started by an electron beam focused on the members and operative only when no arc exists. The members 3 are mounted on a support movable relatively to a tungsten electrode 1<1>, in a chamber 4 that is evacuated by a pump 5. The secondary windings of high and low voltage transformers 6, 7, respectively, having primaries connected in parallel across the supply, are connected in series with the members 3 and the electrode 1<1>. Also connected to the secondary of the highvoltage transformer is a cathode 1 and a focusing electrode 2 which direct an electron beam on to the members 3 to ionize the gap. A triode 13 in a control circuit 11 is biased to conduct by a voltage derived from a resistance 12 in parallel with the arc. The output of the triode 13 energizes the saturating winding 10 of a saturable reactor having an impedance winding 9 in circuit with the primary of the high-voltage transformer 6 which energizes the cathode 1. When the arc strikes the triode 13 ceases to conduct and the impedance winding 9 prevents the transformer 6 from supplying current to the cathode to maintain the electron beam. The method may be applied to the welding of magnesium, beryllium and their alloys and zirconium.

Title: Automatic change-over relay systems for supplying current from a spare current source upon the failure of a main current source
IPC: H02J9/06
Filed: 1946-12-24
Abstract: 622,505. Systems depending on the use of two or more sources. WILCOLATOR CO. Dec. 24, 1946, No. 37902. Convention date, Feb. 1, 1945. [Class 38 (iv)] [Also in Group XXXVII] In a supply system in heavy aircraft, in which a spare inverter is brought into operation upon failure of the main inverter, an arrangement of relays, including a time-delay relay, ensures that the spare inverter is not energized on starting up unless the main inverter is definitely out of action. When switch 32 is closed, relay 16 in the input and output circuits of the main inverter 14 is energized through a contact 38 of a relay 40, and heater coil 50 of a thermal delay switch is energized through contact 46 of relay 40. The A.C. volts of the inverter energize relay 58 and move contact 60 down to keep relay 16 energized when, after a short time delay, thermal switch contact 64 moves down, and energizes coil 68 of relay 40. The consequent downward movement of switch 40 not only breaks the supply to relay 16 through contact 38, but also the supply to the heater of the thermal switch 50. Coil 69 remains energized, however, through contact 70, while engagement of contact 72 ensures that, if the main inverter fails, and contact 60 of the consequently de-energized relay 58 moves up, the relay 20 controlling the spare inverter is immediately energized. If the main inverter is faulty when switch 32 is closed, contact 60 remains in its upper position and relay 20 is energized when switch 40 moves down after the time delay determined by switch 50. A signal 22, operated by a relay 23, indicates inverter failure.
