Patent GB-683563-A (GB)
Title: Manufacture of combustible gas from hydrocarbon oils
IPC: C10G9/38
Filed: 1950-06-26
Abstract: 683,563. Oil gas generation. ALLIED CHEMICAL & DYE CORPORATION. June 26, 1950 [Sept. 2, 1949], No. 15845/50. Class 55 (ii). Oil gas is generated in an intermittent process wherein preheated steam is passed up through an unobstructed reaction zone heated during a previous blow period to cracking temperature, oil being sprayed down through the zone, the gaseous mixture from the reaction zone being led downwardly through a fixing zone. In one form the apparatus consists of a heat storage chamber 1, a reaction chamber 2 and a fixing chamber 3 connected in series by ducts 17 and 26. Chambers 1 and 3 are filled with checkerbrick whilst chamber 2 is unobstructed except for a throat 16 which serves to increase the gas velocity through the chamber. At each end of the plant are riser pipes 9 and 29 closable by valves 11 and 31 and connected by ducts 8 and 28 to the bases of chambers 1 and 3 respectively. The plant operates on a blow and run cycle. During the run period steam enters duct 8 through line 14 and passes up through chamber 1 which has been heated by the previous blow. The superheated steam enters a space 22 beneath the throat 16, where it mixes with a hydrocarbon carrier gas entering through line 21. This gas is recycled by pump 39 from the base of chamber 3 or may be an "external" gas admitted through line 41. The steam-gas mixture passes up chamber 2, meeting a downwardly directed oil spray from jet 25. The oil used may be of low grade such as heavy cracked residuums. Partial cracking of the oil occurs in chamber 2, carbon being deposited on the chamber walls, and the cracking is completed in chamber 3, the fixed gas passing out via riser 29 and line 33. At the end of the run period, the oil is shot off and the plant purged with steam from line 14. Air is then admitted through line 35 and burns the carbon deposited in chambers 3 and 2 during the run, the hot gases heating chamber 1 and exhausting through valve 11. Air is now admitted through lines 12 and 18 and burns heating oil which is injected through line 43 and, if necessary, through line 45, the combustion of this oil heating the chambers 2 and 3 to cracking temperature. After a further steam purge, the run period is recommenced. Specification 683,564 is referred to.

Abstract: 594,094. Delivering articles from shoots and hoppers. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). June 26, 1945, No. 16233. [Class 78(i)] A fastenerassorting and delivery mechanism comprises a raceway including a downwardly extending channel, a device movable across the lower end of the raceway laterally of the channel, to separate the lowest fastener from a row of fasteners in the channel and means arranged not only to impart fastener-separating and return movements to the device but also to cause a lateral blow to be imparted to the raceway as a consequence of each return. Tacks pass out of a tack pot 12 into one of two channels. 20, 22 in the raceway 14 and are removed one at a time by a separating plate 40 which reciprocates in a curved path and delivers the tacks to a tube 26 leading to the separate instrumentalities of the machine. The separator 40 is carried by a bell crank lever 42 connected through gear segments 64, 62 with actuating rod 78 which reciprocates axially to produce the separating movement of the separator 40. On completion of each separating movement the rod 78 is disengaged from the gear segment 64 and the separator returned to its initial position beneath the raceway by a torsion spring 81. A hammer plate 112 is fastened to one end of the separator 40 to jar the raceway and to determine the initial position of the separator. The separator is yieldingly operated because the actuating rod 78 acts through a compression spring 97 in that member. Specification 213,594, [Class 89(iii)], is referred to.

Ornamenting.-A process of vignetting or shading glass, celluloid, or other transparent material for use in spectacles or other glasses or lenses for the prevention of glare or dazzling effects, consists in spraying the surface with a cellulose derivative containing a dye or other soluble co1ouring matter and, after drying, spraying or otherwise applying upon the surface a clear solution of a cellulose derivative to dissolve or disperse globules of colouring matter, which are caused to flow and unite. The matt surface produced upon a sheet of celluloid so treated may be subsequently burnished, or a second sheet of cellulose may be secured upon it by a suitable adhesive, the composite sheet then being burnished in a hot press. In applying the process to non-splintering glass comprising two sheets of glass between which is interposed a sheet or fi1m of a ce11u1ose derivative or clear rubber, the vignetting is produced on the interposed sheet or film, the glasses being coated on their inner face with the clear solution.

As shown, in an aircraft automatic pilot an electrical signal representative of the attitude of the aircraft about one of its axes is developed between line 15 and earth and applied to an amplifier 5, the output of which energizes a reversible servomotor 6 adjusting, through a gear-box 8 and linkage 29, 3, 27, a hydiaulic actuator (not shown) for the appropriate control surface. Rate feed-back is provided by a tachometer generator 7 as in Specification 611,037. To ensure a central datum position for link 29 it is caused to operate a potentiometer 14 forming part of an A.C. bridge circuit, output from which energizes a two-phase servomotor 9 which trims the position of the control surface by adjusting link 3 through gearing 11. Servomotor 9 drives a tachometer generator 10, the output of which is applied through a potentiometer 16 to the input of amplifier 5. The automatic pilot is engaged by operation of a switch 24 to energize a relay 18 moving contacts 19, 20, 21 to the position shown. The automatic pilot is disengaged if relay 18 is de-energized by operation of pushbutton 26 or when a limit switch 17 opens. Manual control of the control surface may be effected by lever 1 acting on link 3, a spring 4 providing " feel." When the automatic pilot is disengaged or when a manually operated switch 25 is moved from the position shown, motor 9 may be controlled manually by a switch 23 to effect trim. Trimming by means of an auxiliary control surface is referred to. Specification 663,542 also is referred to.
