Patent GB-1240841-A (GB)
Title: Automated saw
Inventor: JUREIT JOHN CALVIN
IPC: G05B19/18
Filed: 1968-08-05
Abstract: 1,240,841. Circular saws. AUTOMATED BUILDING COMPONENTS Inc. 5 Aug., 1968, No. 37183/68. Heading B5L. [Also in Division G3] A cutting machine has a cutting means rotatably mounted on a framework in a plane substantially normal to the direction of cut and movable to a selected angular position, and a reference position means carried by the framework located a selected distance from the cutting means, and a programme control arrangement to move and locate the reference means to a selected position relative to the cutter. A flying saw 32, Fig. 13d, is required to cut boards W to a specified length and angle as may be required in the manufacture of wooden roof trusses. The boards are placed in the machine by hand and are butted against one of a series of stops e.g. PC8 arranged at, say, two foot intervals, intermediate distances being determined by moving a table, on which the board is placed, by a series of hydraulic cylinders 19 having their strokes arranged in a geometric progression. The angle of saw cut is determined by a similar series of hydraulic cylinders acting linearly on a rack turning a gear attached to the saw mounting. The board length and angles of cut may be recorded on punched cards, magnetic tape, or punched tape, this information being called out in sequence by a machine operator. At the end of a previous operation the tape is advanced and the work-tabel moved to the required position with the correct stop e.g. PC8 advanced. A board is butted against this stop and a switch CB is operated which operates hydraulic clamps and retracts the stop. A switch SB is then operated which starts the saw motor 340 and the saw is advanced hydraulically to make the cut. At the forward limit of the saw travel a limit switch 928 is closed which retracts the saw and release of switches CB, SB releases the clamps and advances the tape reading arrangement which moves the table and the angular position of the saw through solenoid operated valves LS1-LS256, AS1-AS512. The board is then reversed, placed against an appropriate stop raised by one of magnetically operated valves PS0-PS24 and the process continued by operating switch CB and switch SB.

Title: Solid electrolytic capacitor and method of making same
IPC: B30B11/00
Filed: 1963-10-02
Abstract: 1,066,847. Capacitors. TEXAS INSTRUMENTS Inc. Oct. 2, 1963 [Oct. 11, 1962], No. 38859/63. Heading H1M. A solid electrolytic capacitor comprises an electrode of compacted silicon particles which has been anodized to form a silicon oxide dielectric layer, over which a solid counter electrode layer, such as manganese dioxide, has been deposited. In order to make electrical connection with the silicon electrode a silicon rod is inserted into the compacted assembly of silicon particles before anodization and the whole mass sintered. To make connection with the counter electrode, layers of carbon and of silver are successively deposited upon it. A suitable starting material from which to construct the capacitor is P-type silicon, doped with boron so as to reduce its resistivity to less than 4 ohm. centimeters, of polycrystalline form. This is broken into small irregular particles by severe shaking, after which a mass of the broken particles having cross-sections within a preferred range (75-150 microns) is placed in a latex liner together with a silicon rod, the ends of the liner being stopped. The liner is then placed within a perforated tube, which is sealed within a latex tube and the whole subjected to 10,000-60,000 1b. pressure in a hydrostatic pressing cylinder, to compact the silicon rod and particles. Thereafter the electrode is sintered at 1300‹ C. under pressure in a hydrogen atmosphere. To provide the dielectric film, the silicon electrode is anodized in a solution of potassium nitrate containing N-methyl-acetamide. The silicon electrode is made the positive electrode in this process, while a suitable negative electrode would be platinum. After this step, a layer of manganese dioxide is deposited on the electrode by dipping the electrode in an alcoholic solution of manganese nitrate and then pyrolizing the layer of manganese nitrate so produced. This process is repeated several times, and then a carbon layer is provided by dipping the unit in a solution of chlorocarbon. Thereafter the outside of the unit is painted with silver and potted with a suitable resin within a metal can. Other materials beside manganese dioxide, e.g. lead oxide, cadmium sulphide or pure nickel may be used as the solid electrolyte.

Title: Improvements in or relating to pulse jet engines
IPC: F02K7/06
Filed: 1958-12-05
Abstract: 881,347. Generating combustion products under pressure. CURTIS AUTOMOTIVE DEVICES Inc. Dec. 5, 1958 [March 4, 1958], No. 39333/58. Class 51 (1). [Also in Groups XXVI, XXVII and XXIX] A pulse jet-engine comprises a combustion chamber, a vibratory combustion chamber inlet valve controlling the supply of fuel and air to the combustion chamber, and an air inlet valve assembly having an air inlet chamber for supplying air to the combustion chamber inlet valve and an air inlet valve to allow free flow of air into the air inlet chamber but to prevent reverse flow from the air inlet chamber. As shown, the air inlet assembly 33 is in the form of a cubical chamber 34 connected by a fuel and air-mixing passage 17 of Venturi form to a combustion chamber 11 and has a circular arrangement of air intake ports 39 in each of four walls 35, 36, 37, 38, each such arrangement co-operating with a valve member 48 supported on a wall and having petal-like portions 51 overlying the ports 39. Each valve member 48 is supported or attached to the corresponding wall by a flat back-stop disc 53 and a bolt 52. The fuel and air-mixing passage has a forwardlyflared air intake mouth 18, and encloses fuel and starting air pipes 42 and 30. A plate 32 attached to the down stream end of the mixing passage has a number of ports 16 covered by a vibratory combustion chamber inlet valve 20 with petal-like portions and held in place by a backstop 21. When the engine is operating the periodic partial vacuum formed in the combustion chamber 11 opens the valve 20 and draws in air and fuel from the mixing passage 17. The resulting partial vacuum in the inlet chamber 33 opens the valves 48 allowing ambient air to enter. Pressure rise in the combustion chamber due to periodic combustion closes the valve 20 against the ports 16, thus sealing the inlet passage from the combustion chamber. If valve 20 is faulty, " blow-back " to the atmosphere is prevented because the resulting pressure rise in the chamber 34 closes the air inlet ports 39, thus isolating the chamber 34 from the atmosphere.

The master sheet may be perforated along the marking and may be transparent. The marking serves as a registration line for the edge of the original copy sheet or proof which is put on the assembly with the correctly reading side facing downwards i.e. facing the carrier sheet. The original and the assembly is then put into a screen and fed through a thermographic copying apparatus for setting up the printing master to produce a mirror image on the surface of the master sheet facing the carrier sheet surface. This mirror image may be transferred to copy sheets.
