Abstract: 1304075 Valves L'AIR LIQUID SOC ANON POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES GEORGES CLAUDE 6 May 1970 [7 May 1969] 21922/70 Heading F2V [Also in Division F4] A valve for controlling the supply of oxygen in a welding torch has two closure members 3, 8 which control flow between an inlet 1 and separate outlets 5, 6. Closure member 3 when seated prevents flow to both outlets and when first opened allows a large flow to outlet 5 compared with the flow that closure member 8 allows to outlet 6. Closure member 8 which does not seat acts to meter the flow to outlet 6 whereas closure member 3 acts merely as an onoff valve. Outlet 5 communicates with a central passage 28 in the cutting head through passages 16, 18, manually actuated valve 20 and passage 26. Outlet 6 communicates with a passageway 36 in which the oxygen mixes with acetylene from a chamber 32. The passageway 36 communicates with peripheral passageways 30 in the head. In modifications of the valve, tapered portion 3 is replaced by the flat end of a piston and inlet 1 and outlet 6 may be interchanged.

Title: Automatic registration of colour television cameras
IPC: H04N9/093
Filed: 1972-05-11
Abstract: 1383590 Colour television RCA CORPORATION 11 May 1972 22031/72 Heading H4F Automatic registration of two pick-up tubes of a colour television camera is effected by deriving a deflection control signal for one of the tubes from an indicator signal denoting the time relationship of corresponding edge video signals representing a sharp transition between light and dark areas in the televised scene. As shown in Fig. 3, edge video signals 34 and 35 from the green and red (or blue) pick-up tubes are processed via 1À46 Ás delays 37, 41 and 47, 0À73 Ás delay 44, amplifier 38 which doubles the edge signal amplitude and reverses its polarity, and polarity reversers 45 and 54 to thereby derive a predominantly positive polarity wave 58 and a predominantly negative polarity wave 53 which are supplied to a common output terminal 64 via a negative peak detector 59 and a positive peak detector 62 so as to produce an indicator signal having a polarity that indicates the sense of any time non-coincidence of the red and green edge video signals and an amplitude representative of the magnitude of any time non-coincideuce. This indicator signal is supplied to a positive comparator 65 and a negative comparator 66, Fig. 4, which are also supplied with respective positive and negative comparison voltages from a voltage divider 67. If the indicator signal is greater or less than the respective comparison voltages NAND gates 68 or 69 are activated to pass pulses from a generator 71 to the "up" or "down" control terminals respectively of a counter 72 from which the deflection control signal for the red (or blue) pickup tube is derived. The offsetting of the action of comparators 65 and 66 by the different comparison voltages produces a small dead zone in which small indicator signals produce no change of the deflection control signal. In a second embodiment, Fig. 8, the predominantly positive and negative polarity waves 89 and 95 are derived from the red and green edge video signals 35a and 34a by means of integrators 75, 76, 78, 82, 83 and 85, differentiators 77, 79 and 84 and polarity inverter 91. These signals are then supplied via positive and negative peak detectors 96 and 99 to produce at common output terminal 64 the indicator signal which is supplied to the circuit of Fig. 4, to thereby derive the deflection control signal. An alternate or auxiliary indicator signal may be provided at terminal 64a via negative and positive peak detectors 97 and 98. The image areas of the pick-up tubes are effectively divided into nine zones, the deflection control signal derived from the central zone V, Fig. 1, in response to gated video signals from this zone, is used to effect horizontal and vertical centering of the raster scans; from zones IV and VI horizontal size (width), linearity and raster skew correction; and from zones II and VIII vertical size (height) and linearity correction.

Title: Sulphurisation of organic materials
Inventor: POTTER EDWARD BARRIE VERNON
Filed: 1951-09-21
Abstract: Water-inert fatty oils, unsaturated fatty acids or esters, or terpenes are sulphurized with elementary sulphur in an exothermic reaction, temperature control being achieved by the provision of free liquid water in controlled amounts in the reacting mixture. The process is particularly applicable to the sulphurization of terpenes, e.g. dipentene.  The sulphurization is normally carried out at 135 DEG  to 200 DEG  C. and catalysts may be used, notably rubber "vulcanization accelerators," e.g. mercapto benzothiazole and tetramethyl thiuram di-sulphide.  In an example dipentene, sulphur, water, mercaptobenzothiazole and diphenyl guanidine are fed into the reaction vessel and a sulphurized dipentene is obtained. Specification 688,293 is referred to.

Title: Improved process for making electron-emitting electrodes
IPC: H01J9/04
Filed: 1925-09-05
Abstract: 239,539. Dubilier Condenser Co. (1925), Ltd., (Assignees of Capicotto, J. V.). Sept. 5, 1924, [Convention date]. Vacuum tubes.-An electron-emitting electrode is formed by heating a filament of platinumiridium alloy in contact with a mixture of barium and strontium carbonates in powdered form so as to cause the carbonates to adhere to the filament, which is heated subsequently to a higher temperature to reduce the carbonates to oxides. The. carbonates may be contained in a trough which is moved along the filament. The coating and reducing process may be repeated. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following. The filament may consist of an alloy containing 90 per cent platinum and 10 per cent iridium, or one containing 95 per cent platinum and 5 per cent nickel. Equal weights of the carbonates are ground fine, passed through a sieve of 200 meshes to the inch, and mixed with twice their weight of molten paraffin wax, and the mixture is stirred to form a milky mass, which on congealing, is rolled into sticks. The filaments are stretched on a frame and heated electrically, and the sticks are rubbed along them to form a coating. The filaments are then heated to incandescence to burn away the wax and oxidize the carbonates. The process is repeated several times, and, after the final coat, the filament is maintained at 1000‹ C. for an hour to complete the oxidation. In a modified process the carbonates are dissolved in distilled water to form a saturated solution in which the filaments are immersed and heated electrically to deposit the carbonates. The filaments are then removed from the liquid and heated to incandescence. This subject-matter does not appear in the Specification as accepted.
