Abstract: 1,206,882. Turret lathes; workpiece transferring. INDEX-WERKE K.G. HAHN & TESSKY. 1 May, 1968 [19 May, 1967], No. 20698/68. Headings B3B and B3T. [Also in Division F2] Cyclically variable speed drive of a cam 52, e.g. for effecting slow feed and quick return of the carriage 14 of a turret lathe 10, is effected by a three element planetary train 60, 72 and 80, the planet carrier 72 of which carries the cam 52 and a pair of planet wheels 76, 78 meshing the ring gear 60 which is continuously driven by a worm 58 meshing external teeth on the ring 60 for slow feed, and also meshing the sun gear 80 intermittently driven, e.g. by a Geneva mechanism 92, in the same direction of rotation as the ring gear for quick return. As shown in Figs. 1 and 2, the carriage is driven by the cam 52 through a crank 42 carrying a follower 50 and a toothed segment 40 meshing a rack 34 slidable in the carriage and connected by a link 38 to one wheel 36 of a Geneva mechanism which indexes the tool turret 26. On rotating the cam 52 clockwise, as shown, the follower 50 moves up one cam face to feed the carriage slowly, the cam 52 being driven by the ring gear 60 only. On the follower reaching the end of one cam face, the sun gear 80 is rotated to rapidly rotate the cam so that the follower is moved rapidly to the leading edge of the next cam face by a spring returning the carriage to its initial position. Activation of the motor driving the sun gear 80 is effected by an adjustable trigger on flange 98 of ring gear 60 which abuts a switch. Both Geneva mechanisms 92 and 36 may be driven by the same motor, or mechanism 92 may be replaced by an electromagnetic clutch. Again, Fig. 4, a pair of cams 156, 158 on a planet carrier 146 control and effect the longitudinal and turning movement of a vertical control shaft (126), Fig. 3 (not shown), of a transfer arm (128) for transferring vertical workpieces (134) from a first station (132) where they are cut from stock by a tool (118), e.g. mounted in the turret 26 of Fig. 1, to a second station (120) where a groove is formed in the workpieces. The cams act through levers analogous to the crank 42 of Fig. 1. The carrier 146 is driven slowly by a ring gear 138 with the sun gear 154 stationary, and quickly by the ring gear and sun gear rotating together to effect quick transfer of workpieces. Switches 174 and 169 are acted upon by triggers 168, and 170, 172 on the ring gear 138 and fast with the sun gear 154 respectively, to actuate the driving motor 164 of the sun gear to provide rapid movement of a gripper (130) on the transfer arm (128) into engagement with a workpiece just prior to its complete severance from stock. The sun gear is then stopped until severance is completed, when motor 164 is again started to move the workpiece to the next station (120). The motor is then stopped and the workpiece is fed slowly to form the groove, e.g. by a circular saw.

Couplings, automatic.-The draw-bar of each tramcar carries two complementary heads c, c1, and d rotatable about a perpendicular pin b. The coupling-head d has an enlargement at the end which forms a hook d2, behind which an unlocking cone h is slidably mounted, and an eye d4 is formed on the longitudinal axis for the reception of the tumbler safety-bolt e3 which is pivoted at e1 to the top half c, of the coupling c, c1. A safety-catch f is secured by the bolt f1 and operated by a spring g in the slot d5. The coupling-head c, c1 is of hollow conical shape, in halves. The top half c1 is hinged at c2, slotted to receive a tumbler safety bolt e and guided by dowel pins c,. The end of the hollow cone and the end e2 of the tumbler bolt are recessed to fit the enlarged head d2 of the hook d, notches c4 engaging with corresponding notches d, of the hook. In the unlocked position, the tumbler bolt c hangs with its heavy end e2 nearly vertical. When engagement takes place, the hook d enters the hollow cone of the coupling c, c1, and rises up the inclined surface of the lower half c, pushes the end e2 of the tumbler bolt e into the back of its recess in the top half c, and raises the tumbler bolt and top half about the hinge c2. When the notch d1 of the. hook slips over the notch c4 of the lower half of the coupling c the top half falls back into place, the bolt e3 drops into the eye d4 and is retained in the locked position by the catch f engaging with the recess e4.To disengage, the catch f and unlocking cone h are forced apart by the forked rod i. The backward movement of the catch f releases the bolt e, and the forward movement of the unlocking cone h wedges the top half c, away from the lower c, carrying the bolt e3 clear of the hole d4.

Abstract: 1,115,809. Detecting neutrons. ELECTROSPACE CORPORATION. 11 May, 1966 [16 July, 1965], No. 20916/66. Heading G6P. In a dosimeter, neutron and gamma ray intensities are measured respectively by a solid state diode and a radio photoluminescent glass member. Both are mounted together in a cylindrical case and the glass member has a lead and bronze shield which serves to reduce the response peaks inherent in the glass. The bronze lowers the effect of the lead K-absorption edge, producing a flatter characteristic. The glass member is silver activated phosphate glass and a silicon diode is employed. The gamma ray measurement is effected by luminescent light emitted from the glass upon the application of ultra-violet light and the neutron flux measurement is made in an electric circuit connected to the diode output terminals.

Title: Improvements relating to thermographic printing
IPC: G03B15/00
Filed: 1960-06-15
Abstract: 894,527. Thermographic contact copying processes and apparatus. WARREN CO., S. D. June 15, 1960 [June 22, 1959], No. 21042/60. Class 98(2). Copies of an original are made by reflex exposure to a source of radiant heat of a sandwich consisting of a heat sensitive transfer sheet bearing on its inner surface a heattransferable layer, a copy or receiving sheet, and an original, the primary radiation from the source being chiefly of a wavelength to which the transfer and copy sheets are at least partially transparent and the image areas of the original being such that they are heated by the transmitted primary radiation and reradiate at a wavelength which causes selective transfer from the transfer sheet to the copy sheet. Typically the primary radiation is of wavelength 5,000 to 50,000 A, the support layer for the transfer sheet and the copy sheet are of paper and the heat-transferable layer is a wax containing a dye or pigment. Instead of plain paper the copy sheet may be paper with a clear wax or smooth mineral coating or a cellulose acetate film. As shown a transfer sheet 15 is fed through a contact printer by a motor driven roller 28, the sheet being tensioned by an idler roller 18 acted on by .a friction brake 34. A copy 17 and an original 44 are drawn along by the sheet and exposure is effected when the sheet sandwich passing round the roller 22 moves past an infra-red lamp 48, transfer taking place shortly after the exposure as the transfer sheet is smoothed into contact with the copy sheet by a sponge rubber block 56 having a smooth limp surface. To avoid heating of the lamp, the radiationconfining bright reflector 50 and the air in the vicinity and so avoid undesired re-radiation from them of long wavelengths, cooling air is blown through and past them from a fan 52. The original and printed copy sheet are delivered at the front of the machine, a knife 42 enabling the printed copy sheet to be severed from the web 17, and the used transfer sheet passes to waste at the rear of the machine. In an alternative embodiment, e.g. for copying books, the copy or receiving sheet is a cut sheet and the sandwich is held by pneumatic pressure or vacuum against a glass plate through which radiation is directed from a light source and reflector unit which traverses the sheets, the carriage for this supporting also a take-up reel for the used transfer sheet.

Abstract: 1425186 Mining conveyers GEWERKSCHAFT EISENHUTTE WESTFALIA 4 May 1973 [5 May 1972 15 July 1972] 21284/73 Heading B8A Hydraulically operated tension means 21-25 is attached by a bracket 26 to a channel section 10 of a longwall conveyer but the tension means operates only when roof props 12 to which the means is connected, reach a predetermined setting pressure. The tension means includes a piston-cylinder unit 22 and is connected to an anchor beam 17 movable transversely of the length of the conveyer by a ram 18 which is controlled by a sensing element 20 whose head 75 engages the conveyer. The props 12 are associated with a further pair of props 14, each pair being mounted on a support frame I, II. Assuming that frame I has been advanced, the props 12 are extended and, when the setting pressure has built up, a valve (63, Fig. 2, not shown) in an hydraulic interlock circuit opens and the piston-cylinder unit 22 is energized thus exerting tension in the direction P and consequentially tensioning the remainder of the conveyer. If the pressure in the props 12 drops, or is lowered to permit advancement of the frame I, pressure to the unit 22 is automatically reduced and no tensioning force acts on the conveyer. A further valve (64) ensures that the unit 22 remains pressurized while support frame II is advancing. A double-acting hydraulic ram of a guiding and shifting means 11 enables the frames I, II to be advanced alternately. When the conveyer advances, the sensor 20 causes the ram 18 to be energized and by extending the anchor beam 17, the tension unit 22 is maintained parallel to the conveyer. In a modified arrangement, (Figs. 4, 5, not shown) a control unit (100) is mounted on the piston-rod of the tension unit (22) and includes three interlocking servo control valves (112, 114, 113) which, unless operated in sequence by sufficient pressure in the props 12, prevent actuation of the unit (22). In the event of pressure drop in the fluid supply, the tensioning means remains in operation.
