Inventor: FABER PETER
IPC: H01M4/64
Filed: 1969-06-16
Abstract: 1,209,018. Sintered Ni-electrode plaques. RHEINISCH - WESTFALISCHES - ELEKTRIZITATSWERK A.G. 16 June, 1969 [20 June, 1968], No. 30483/69. Heading H1B.

Patent GB-446505-A (GB)
Title: Process and apparatus for the manufacture of active carbon
IPC: C01B32/336
Filed: 1934-10-24
Abstract: <PICT:0446505/III/1> <PICT:0446505/III/2> Active carbon is obtained by spreading out carbonaceous material in a highly heated condition in a thin layer upon a stationary support within a reaction chamber, mechanically stirring the material upon the support, circulating a mixture of activating gases--CO2, H2O- and combustible reaction products--CO2, H2,--at high temperatures in a plane substantially parallel to the surface of the material so that the gases and vapours continuously sweep the surface, and introducing oxygen or oxygen-containing gases through a large number of inflow apertures above the support so that the oxygen burns in the reaction products with short inverted flames and there is substantially no contact between the oxygen and the carbonaceous material.  The carbonaceous material in granular or powdery form may be moved counter-current to the hot gases evolved in the process so that it is dried, heated, de-gasified and carbonized before entering the reaction chamber.  As shown, carbonaceous material is introduced at 1 into a multi-zone retort and moved continuously by scraper teeth 3<a> on hollow arms 3 attached to a hollow shaft 2, the material passing through drying, slow heating and calcining zones 4, 5, 6 to the reaction chamber 7. Oxygen or air, with or without steam, passes through a central, hollow tube 11 furnished with branch tubes 12 extending within the arms 3 and emerges through horizontal or upwardly inclined apertures 14 where the oxygen burns with short, inverted flames. The tubes 12 may be provided with adjustable throttling members to regulate the stream of gas in any zone.  The activated material passes to the lowest zone 8 when it is maintained at a high temperature for some time, to increase activity, and alternately leaves by outlets 9. Gases and vapours pass off through an outlet 15.  In a modification, the oxygen or oxygen-containing gas is supplied from an outside source and is blown through tangential passages 16, Fig. 4, into the upper portion of the reaction chamber.  Combustible and reaction products in the reaction chamber are sucked in through radial, downwardly inclined passages 17 communicating with the passages 16. Suitable carbonaceous materials are wood, peat, wood charcoal, brown coal, peat coal, pit coal, anthracite, and waste combustible materials, e.g. sawdust.

Title: Drive Coupling System
IPC: G11B17/34
Filed: 1968-06-27
Abstract: 1,179,668. Motion transmitting means. INTERNATIONAL BUSINESS MACHINES CORP. 27 June, 1968 [13 July, 1967], No. 30627/68. Heading F2Q. [Also in Division G5] Means for feeding material 17 such as magnetic tape or a card or ticket bearing magnetic data comprises an inclined driving shaft 11 connected by a universal joint 23 and a support 13 to a feed wheel 16. In the inoperative position the support 13 hangs vertically and the feed wheel is spaced from the material, but on rotating the driving shaft the feed wheel tends to assume a concentric position and is pressed into friction engagement with the material to feed it along a backing plate 12. The reaction of the material causes the support and feed wheel to tilt slightly in a plane parallel to the backing plate so that the force transmitted to the material has a slight downward component which urges the material against an alignment surface 19. An idler roller 18 may be provided in the backing plate opposite the feed wheel.

Title: Improvements in indexing mechanism
IPC: B23Q5/20
Filed: 1946-10-15
Abstract: 618,483. Thread grinding. JONES & LAMSON MACHINE CO. Oct. 15, 1946, No. 30680. Convention date, Oct. 16, 1945. [Class 60] Machines for grinding threads and the like are provided with a rotary work spindle, means for rotating said spindle, means for moving said spindle axially in predetermined relation to said rotation, means, including a planetary transmission having a normally stationary part, between said rotating and moving means, and power means comprising a motor for turning said normally stationary part at intervals to thereby change the angular relation between said rotating means and said moving means. In a multi-start thread-grinding machine of the type, for example, as that described in Specification 478,757, in which the work is traversed and rotated by lead screw and spindle driving mechanism, a work spindle 3, Fig. 3, is rotated by a gear 7, driven through reversing mechanism from a drive shaft 75 (not shown), through a lost motion device 15, 16, 17 and a ring 13 to a sleeve 8 having a bevel gear 18 which drives pinions 19 journalled in a normally stationary spider 21, the pinions 19 driving a bevel gear 22 keyed to the spindle 3. At the end of each grinding pass a motor 45, Fig. 9, is actuated to turn the spider 21 and thus give the work an extra, indexing, rotation. The spider 21 meshes with a worm 26 geared to a shaft 30 driven by a worm 33 and a worm wheel 31 driven by a pulley 42 from the motor 45. The means for actuating the motor include a solenoid 50 energized by the closing of a switch operated by a dog on the reciprocating carriage as the carriage approaches the end of its stroke. The solenoid lifts a pivoted latch dog 56, which contacts a locking shoulder 58 on a cam 32 mounted on the shaft 30, to allow the shaft 30 to rotate and at the same time the dog 56 lifts an element 61 to close a switch 63 which causes switch arms 65, 66 to close a holding circuit for a relay 64 and to energize a motor 45. Rotation of the shaft 30 continues until a cam 70 adjustably fixed to the cam 32 opens a switch 72 which stops rotation of the motor, any continued rotation of the motor after the shaft 30 is positively stopped by the dog 56 contacting the shoulder 58 is taken up by moving the worm wheel 33 along its shaft against the action of a spring.

Filed: 1961-08-30
Abstract: 943,856. Electric selective signalling systems. GENERAL ELECTRIC CO. Ltd. Aug. 20, 1962 [Aug. 30, 1961], No. 31280/61. Heading G4H. In a position encoder first and second conductors are wound through the gaps between the teeth of a ferro-magnetic core, and a small ferromagnetic element is mounted for movement adjacent the ends of the teeth so that the reluctance of the magnetic circuit completed by the element is reduced, the coupling between the first conductor and the second conductors in each gap being characteristic of the relative positions of the element and the core. Fig. 2 illustrates a cross-section of a shaft position encoder. Each gap contains second conductors 10-14 and first conductor 8 or 9. The shaft carries a ferro-magnetic element 5 which is sufficiently large to bridge two teeth at all times. The wiring of the encoder, Fig. 3 (not shown), is such that if A.C. is applied to conductors 8, 9, Fig. 5, signals appear in conductors 10-14 in a combination unique to the current position of the shaft. After phase detection in units 29, such as described in Specification 919, 835, a parallel mode two state signal appears at 30-34. The embodiment of Fig. 5 includes a second, and identical, encoder 27<SP>1</SP> which is coupled to the shaft driving encoder 27 by a 16: 1 reduction gear. Encoders 27<SP>1</SP> and 27 thus provide coarse and fine signals respectively. To compensate for back-lash in the gears and to ensure accurate changeover from one coarse position to the next for each sixteen steps of the fine scale, the most significant digit of the fine scale is used to energize either winding 8<SP>1</SP> or 9<SP>1</SP> (which together constitute the first conductor) and which correspond to the even-numbered and oddnumbered gaps in the coarse encoder. If a serial mode signal is required, D. C.pulses are applied in turn to the second conductors, a serial mode signal then appearing on the first conductor. Specifications 863,027 and 920,535 also are referred to.
