Title: Document transport system
IPC: B41J11/00
Filed: 1971-06-17
Abstract: 1354368 Feeding sheets BURROUGHS CORP 17 June 1971 [6 July 1970] 28383/71 Heading B8R [Also in Division B6] A machine for handling documents having a machine readable portion thereon, e.g. a selective printing machine having a printing head 36 and platen 34 for printing selected lines of a business form 50, has at least one gripper movable in opposite directions along a guide track, means for keeping taut a document moved back and forth by said gripper and a transducer means operable to read the machine readable portion. Two grippers may be provided one on each of two carriages 48 underslung on two parallel tracks 44 the inclination of which may be adjustable. The carriages are reciprocable along the tracks by a reversible motor 80 which drives a shaft 46 on which are wound cables 58 attached to the carriages. The position of the grippers on their tracks, and hence the line of the business form at the printing position, is sensed by a photo-electric cell which counts the slots in a slotted disc 88 on drive shaft 46. The shaft is stopped in correct position by a solenoid operated clapper (102), Fig. 20 (not shown), and pawl (104) which engage a toothed wheel 96 on the shaft. In operation, as a document 50 is inserted into the throat of the machine its leading edge trips a vane (266), Fig. 25 (not shown), which blocks light to a photo-cell thereby actuating feed rollers 125. At the same time the gripper carriages are urged to their end position causing the grippers to be opened by the action of a roller (168), Fig. 9 (not shown), on a cam track or by a lever system, Fig. 17 (not shown), for reception of the document leading edge which is sensed by a second photo-cell (240), Fig. 25, activating motor 80 which drives the grippers to pull the document into the machine with the aid of the feed rollers 125 which rotate relatively slowly and co-operate with a guide 231 to keep the document taut. During this insertion magnetic information carriers 54 on the document are read by the transducer (56), Fig. 4 (not shown), the line position information thereon being stored so that during subsequent movement of the grippers in the eject direction, the document can be stopped at appropriate positions for printing. During this movement rollers 125 again keep the document taut by relatively fast rotation. The document is then moved in the insert direction again, then ejected during which time updated information is applied to the magnetic carriers by the transducer. Alternatively, printing may occur during the first insert movement.

Filed: 1958-09-04
Abstract: 856,539. Supporting filaments in electric lighting and heating apparatus. GENERAL ELECTRIC CO. Ltd. Aug. 27, 1959 [Sept. 4, 1958], No. 28448/58. Class 39(2). In devices for producing light or infra-red radiation consisting of a helix 6 of refractory metal, such as tungsten, supported in a closed vitreous envelope 1 between supply conductors 5 sealed into its ends, the helix 6 being spaced from the wall of the envelope by refractory, e.g. tantalum, spacers 7 at regular intervals, some at least of the spacers are fixed in position by being partly embedded in the wall of the envelope. By this means a long filament can be used in a vertical position without sagging. The embedding can be effected by heating the envelope adjacent the selected spacers, e.g. at diammetrically opposite points, and pressing the envelope into contact therewith at the softened parts or, when the pressure inside the envelope is below atmospheric pressure, by applying heat to the envelope at diametric opposite points adjacent the selected spacers so as to cause local collapse of the walls on to them. The invention is particularly applicable to heating devices of the type described having a quartz envelope.

Title: Treatment of oil-contaminated clay
IPC: B01J20/12
Filed: 1951-12-07
Abstract: Oil-contaminated clay is purified by feeding into a distillation zone into the base of which a stream of air and hot clay is injected at a rate sufficient to allow a portion of the oil to burn and to provide sufficient heat to vaporize the remainder; the air and vaporized oil maintain the clay as a fluidized bed from which it is continuously removed and circulated in another stream of air in a regeneration zone where the carbon is burnt off the clay, from where a portion of the clay is recycled to the base of the distillation zone.  The clay treated may be spent clay from the refining of lubricating oil.  The temperature of the distillation zone may be 800 DEG -1100 DEG F.  The oil vapours from the distillation zone may be condensed and a portion of the oil mixed with the clay injected into the distillation zone; the remainder may be recovered as gasoline and fuel oil.

Abstract: 665,077. Water-gas generation. STANDARD OIL DEVELOPMENT CO. Nov. 9, 1949 [Jan. 3, 1949], No. 28725/49. Class 55 (i). In a fluidized gasification process in which the carbon content of the solids in the gasification zone is maintained below 30 per cent and preferably between 5 and 20 per cent, gasification residue is withdrawn and passed to a combustion zone where the heat evolved is used to superheat the steam required for the gasification zone. In a modification the steam is also generated by the heat of the hot solid residue and the heat exchange contact between the hot solid residue and the water or steam may be direct or indirect. As shown in Fig. 1, gasification residue is withdrawn from the zone 7 through the line 14 and passed together with air to a combustion vessel 16. Heated solid residue is withdrawn from the vessel 16 via the line 21 and is brought into contact with steam or water in a vessel 23, the steam or water being admitted through the line 22. Superheated steam passes via the line 5 to the gasification zone 7; residue from the vessel 23 may be rejected through the line 28 or recirculated by the line 26. A temperature of 1400-2000‹ F. is maintained in the gasification zone by partial combustion although some of the heat required may be supplied by the superheated steam. Pressures up to 600 lbs. per sq. inch may be employed. The combustion of and contact of the solid residue with the steam or water may be carried out in a single zone and the steam or water may in this case be passed through a coil in the zone. Specification 585,354 and 586,391 are referred to.
