Abstract: 1341447 Data processing INTERNATIONAL STANDARD ELECTRIC CORP 15 July 1971 [23 July 1970] 33187/71 Heading G4A A memory ME is divided into sectors such as SCO, SCC and is accessed by instructions such as INS which include an operation code C, a partial address Y specifying a particular memory cell within a sector and an addressing indicator K which specifies a sector and the type or combination of types of addressing operations to be performed i.e. direct, indirect and/or indexing. In the embodiment shown the memory ME has 2<SP>16</SP> memory cells each of 16 bits, sectors SCC, SCZ (which contains only addresses of branch instructions IB) and sector SCO each contain 2<SP>9</SP> memory cells, the partial address Y is 9 bits long and the addressing indicator is 2 bits long. An instruction INS read from the central cell L of sector SCC having K=01 causes direct accessing of cell L+Y in sector SCC, the sign of Y being indicated by bit 7, for example to extract a data item d1, whereas with K=00, 10 and 11, a data item d0 is directly accessed from address Y in SCO, a data item d2 is indirectly accessed via cell Y (e.g. 84) in SCO, and an indirect address (e.g. 20071 specifying the first cell of a table tb) is indexed with the contents of a register X to access any cell in the table tb, respectively. A branch instruction IB accessed from the memory has an identical format to the instruction INS but the indicator K is interpreted differently. If K=01, SCC is accessed directly at cell L+Y; if K=11, indirect accessing is performed via cell L+Y; if K=00, indirect accessing and indexing is performed to reach cell L+Y+X; and if K=10, indirect accessing is performed via cell 1024+Y in SCZ.

Abstract: 1414366 High methane content gas METALLGESELLSCHAFT AG 13 July 1973 [14 July 1972] 33613/73 Heading C5E A gas having a high methane and low hydrogen content and which is interchangeable with natural gas is produced by reacting evaporable hydrocarbons in a rich gas reactor with water vapour on a nickelcontaining catalyst at a temperature of 350‹ to 600‹ C. and under elevated pressure to produce a rich gas primary product, the hydrocarbons and the water vapour being fed to the reaction in a mixture with a first partial stream of product gas from which substantially all carbon dioxide has been removed and which contains at least 90% by volume of methane on a dry basis. The rich gas primary product of the reaction is cooled by being sprinkled with water in a cooler, the carbon dioxide is scrubbed out in an absorber, and the water which has been heated in cooling the rich gas primary product is directly contacted in a saturator with the first partial stream of gas from which substantially all carbon dioxide has been removed to reheat the gas and enrich it with water vapour; the reheated enriched first partial stream is then passed to the inlet of the rich gas reactor. A second partial stream is branched from the cycle between the carbon dioxide absorber and the saturator. The second partial stream may be passed through a methanization stage. Part of the rich gas primary product may be added to the second partial stream prior to methanization. The ratio by volume of second to first partial stream is from 0À6 to 1À2 : 1. 0À5 to 0À8 kg. live stream is used per kg. hydrocarbon to be reacted.

Abstract: 1,018,251. Gas blast switches. A. REYROLLE & CO. Ltd. Sept. 3, 1962, No. 33768/62. Heading H2B. In a gas blast circuit breaker of the type in which the main contacts 12, 16 are in a chamber 11 permanently filled with compressed gas and an impedance 43 is switched in parallel with the main contacts during each opening operation, the gas blast is initiated by a valve 21 opened when the contacts 12, 16 open and is stopped by a second valve 46 whose moving member carries the contacts 49 of the impedance switch. In a first embodiment (Fig. 1, not shown) valve 21 is rigidly coupled to moving contact 12 and they are opened by venting cylinders 24, 30 through a control valve 53. Valve 53 also supplies compressed air through a pipe 64 to move valve 46 a short while later to separate resistor contacts 49, 50 and then to close the exhaust 67. The contacts are reclosed by repressurizing cylinders 24, 30 through valve 53, an extension of the rod 27 of valve 21 ensures that valve 46 is opened and the resistor contacts closed. In a second embodiment (Fig. 2) both the main contacts 103, 104 and the resistor contacts 119, 120 are housed in the gas-filled chamber, the blast is initiated by a valve 135 which also vents cylinder 107 to move a piston 106 to open main contacts 103, 104. A rod 153 couples piston 106 with a valve 150 which allows compressed gas to enter above a piston 114 driving the latter downwards first to open resistor contacts 119, 120 and then to close exhaust valve 130 to stop the blast. The contacts are reclosed by repressurizing cylinder 136 to reclose valve 135 when cylinder 107 is refilled with gas via flap valve 141 and the parts are returned to the positions shown.

Title: Improved apparatus for the surface hardening of metal articles
IPC: C21D1/08
Filed: 1935-12-06
Abstract: 466,812. Surface hardening metal articles. I. G. FARBENINDUSTRIE AKT.- GES. Dec. 6, 1935, No. 33852. Convention date, Dec. 29, 1934. [Class 72] Apparatus for surface hardening metal articles, e.g. toothed wheels, comprises a member, operatively connected with the burner, which is rotated at a constant speed and is caused to move over a path so that the direction of movement of the member differs over different parts of the path and the burner is consequently moved over the surface to be heated at a speed determined by the shape of the path. When treating the surface of a toothed wheel, a burner carriage 3 is movably supported on a carriage 2 mounted on a frame 1. Slidably arranged in the carriage 3 is an arm 4 which by means of a wheel 5, driven at a constant speed, is caused to follow the path of a fixed cam 6 the shape of which is determined according to the shape of the wheel to be treated. The wheel 5 may be kept in contact with the plate 6 by a magnetic device. In operation, the burner is positioned adjacent the top left edge of a wheel tooth, the wheel 5 being at the left rear corner of the plate 6. When the wheel 5 moves forwardly the burner remains fixed, but as soon as the wheel 5 turns the corner of the plate 6, the burner is moved along the tooth until the edge of the latter is reached. The wheel 5 then moves round the corner of the plate 6 and returns to its initial position with a quick return motion when moving over the hypotenuse of the plate 6. The quick return motion of the burner may also be effected by providing a second cam plate and arranging it to be traversed by an idle running wheel driven by a weight. Specification 446,821 is referred to.
