Title: Improvements in tool adjustment and replacement mechanism for automatic lathes and like machine tools
IPC: B23Q16/06
Filed: 1955-10-07
Abstract: 783,144. Automatic-lathe details. SENECA FALLS MACHINE CO. Oct. 7, 1955 [Aug. 19, 1955], No. 28668/55. Class 83 (3). An automatic-lathe has work-gauging mechanism in combination with a rotatable toolholder in which a number of cutting-tools are mounted in a circular series with one tool only in the cutting-position, incremental advancemovements being given to this tool on indication of work oversize and, after a predetermined number of incremental advances, means operative to retract and index the tool-holder to bring a new cutting-tool into operative position. A number of tools T are carried in a turret-head 10 rotatably-supported by a housing 12 forming part of a transverse-slide 14. The latter is movable in a longitudinally-adjustable carriage 16, fed for turning work W by means, not described. A known gauging-device G bears against the work behind the tool-cut and, on a predetermined over-size of the work, operates a solenoid S, which moves a rack 41 and rotates a pawl-carrying wheel 32. The latter thus rotates a ratchet-wheel 30 through a tooth increment, in turn rotating a cam 25 which bears against a roller 24 secured to a slide-bar 20 intersecting the slide 14. A cam 22 secured to the slide-bar 20 bears against a fixed roller 23 so that, as the slide-bar is moved by the cam, the tool-head is fed towards the work to correct the oversize. When a tool has worn so that it has been advanced the full range of the cam 25, a stop-pin 50 on the cam closes a switch 51 operating a solenoid 52, which, through further rack-and-pinion and ratchet-gear, rotates the tool-turret one step. The tool is thus changed automatically and the slide-bar 20 is returned to its initial position ready for a fresh cycle of incremental feeds with the new tool. This process is repeated for all the tools, after which a switch 88 is opened to stop the machine. An eccentric pin 85 is moved by a lever 84 and solenoid 82 to clamp the turret-head 12 in its housing 14. A locking-ring 70 on the lower end of the turret-head has four notches and is engaged by a locking-pawl 72 when a tool is brought into the required position.

IPC: H01L27/07
Filed: 1966-06-28
Abstract: 1,079,630. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 28, 1966, No. 28930/66. Heading H1K. The integrated differential amplifier shown functions as the equivalent of two transistors with emitters short-circuited and with resistors joined base-to-base and collector-to-collector. The effects of these interconnecting resistors may be minimized by control of the geometry and resistivity of the base and collector layers. The effect of inter-collector connection can be further minimized by cascading respective outputs with two transistors from the collectors of which the final difference signal is taken (Fig. 4, not shown). In a modified structure the emitter region is divided so that a third, centretap, base contact may be provided which in operation is connected to a source of reference potential. In the structure shown the collector region 2 is formed by epitaxial deposition of a 5Á thick layer with a dopant concentration of 10<SP>16</SP> atoms/cm.<SP>-3</SP>, the emitter region is 1.2Á thick and the base region is 0À3 Á thick. The buried N<SP>+</SP> layers SC1, SC2 help keep the collector currents of the two halves separate.

Title: Improvements in devices for regulating or controlling the output of fluid compressors
IPC: F04B39/12
Filed: 1925-11-18
Abstract: 257,787. Browett, Lindley, & Co., Ltd., and Sollors, W. H. Nov. 18, 1925. Regulating compression. - The output of compressors is regulated by inwardly opening main valves which control clearance chambers and have corresponding pilot valves which relieve the pressure on the inner sides of the main valves prior to their opening under fluid pressure controlled by a loaded valve member. The compressor cylinder 13 is connected with the clearance chamber 1 through a passage 9 controlled by a main valve 19 having apertures 21 which may be covered by a pilot valve 22 fixed to the rod of a piston 17 which is actuated against spring pressure either by the pressure of compressed fluid entering through a pipe 34, or by a hand wheel 53. The movement of the piston first opens the pilot valve and thus relieves the main valve of pressure: a collar 23 on the rod then opens the main valve. A similar valve device controls the passage between the clearance chambers 1, 3. which are cooled by the water spaces 6, 8 and this arrangement of valves and clearance chambers is duplicated on the other side of the piston head. The entry of compressed air to the pipes 34, 35 controlling the pistons, from a common receiver 29, Fig. 6, fed from the compressor, is controlled by a series of valves 31 each having a spindle 42 which supports its load and is acted upon by the receiver pressure. In the position shown, the pipe 35 is opened to atmosphere through the passage 45; when the receiver pressure rises sufficiently, this passage is closed by the larger and lower end 43 of the spindle, and the pipe is opened to the receiver pressure through the passage 44. By unequal loading the valves are opened in given order. Damper, dashpot, or other means may act on any of the valves to prevent sudden changes in output. Sleeves 48 may be adjusted to raise the loads of any of the loaded valves, allowing these valves to remain permanently open. The system may be applied to a compound compressor, each loaded valve controlling more than one pipe leading to corresponding clearance chambers in the different stages.

Filed: 1920-10-16
Abstract: 174,165. Moeller, J., and Fonblanque, L. de. Oct. 16, 1920. Coking processes.-Coal or other carbonaceous material is treated in an externally heated retort with a gas containing 60 to 70 per cent of hydrogen or with a mixture of such gas and superheated steam at a temperature of from 500 to 600‹ C. whereby an increased yield of condensable hydrocarbons, ammonium sulphate, and coke is obtained. The coal is charged into a vertical retort a enclosed in a wall f and having a perforated valve d for admission of the gases and for discharging the coke. Hydrocarbon oil, a by-product of the process, from a tank m is sprayed with steam from a boiler o<1> into a vaporizing-chamber l from which the mixture enters and is heated in iron pipes i communicating by a conduit k with the inlet h of the retort a. Superheated steam may also be supplied from a nozzle q. The hot gases from the furnace j serve to heat the pipes i and pass by a flue s to the space g around the retort. The distillation products leave the retort by an outlet c. A rotary ram u, Fig. 2, having ribs on its underside and operated by a hand-wheel w serves to consolidate the fuel in the retort if required. To obtain a hard coke, during the last 20 to 30 minutes of coking the gas and steam or steam alone may be introduced at a temperature of from 700 to 900‹ C.

Title: Improvements in apparatus for separating sheets from a pile of sheets
Inventor: BATTEY ALFRED PIERSSENE
IPC: B65H3/08
Filed: 1950-11-30
Abstract: 710,487. Feeding sheets. CRABTREE & SONS, Ltd., R. W. Sept. 19, 1951 [Nov. 30, 1950], No. 29402/50. Class 100 (1) In apparatus for separating sheets from a pile of the kind comprising a pneumatic sucker carried on a reciprocatory ram mounted in a cylinder and adapted to be lowered thereby to move the sucker into contact with the top sheet of the pile and then raised to li't the sheet, the cylinder is supported from a point above the sucker for universal swinging movement from a datum position within limits allowing movement transversely towards the centre of the sheet and longitudinally thereof. The invention is applied to a sheet separating apparatus operating as shown in Fig. 2, the suckers 6 being mounted near the rear edge of the sheet and lifting the corners, a presser foot 7 preventing lift of the center of the sheet. As the sheet bends about the foot 7 the points of attachment of the suckers tend to move towards each other. Since the rear comer of the sheet is lifted there is also a tendency for the point of attachment of the suckers to move forward. The universal mounting of the cylinder allows the sucker to accommodate itself to both these tendencies. Fig. 4 shows the mounting which comprises a bracket 16 carried on a clamp member 20 adjustably secured to a rail 17 and a part-ball joint 15 the socket of which has an extension 14 secured to the cylinder 11. The clamp member 20 has a support for pipes 23 carrying nozzles 8 adapted to deliver a blast of air under the top sheet to facilitate its separation and to lift its other end into engagement with forwarding suckers 9 which swing to advance the end of the sheet between forwarding rollers 10. As shown in Fig. 5 the cylinder 11 is urged by a light spring 19 to a datum position (e.g. normal to the sheet) where it engages a peg 18 and a part 16<SP>1</SP> of the bracket 16. Movement away from the datum position is limited by a finger 25 surrounding the cylinder on the other two sides. To provide for the change of angle of the sheet at the point of engagement with the sucker the sucker 6 may be mounted on a ball joint or, as shown in Fig. 4, it may have a flexible neck 28. Weights 26, Fig. 2, free to rise or fall in guides 27, bend down corners of the sheet and maintain the sheet approximately level at its points of contact with the suckers. The presser foot 7 may also be adapted as described in Specification 710,501 to act as a pile height detector controlling pile lifting gear.

Abstract: 1,196,059. Tenebrescent materials and uses thereof. FERRANTI Ltd. 12 June, 1969 [20 June, 1968], No. 29416/68. Heading C4S. [Also in Division H1] A cathode-ray tube includes a screen 13 comprising a terebrescent crystalline layer of calcium fluoride doped with oxygen, e.g. 750 to 10<SP>3</SP> atoms per 10<SP>6</SP> Ca atoms. The material may be synthetic or naturally occurring fluorospar, and Na and Ce may be included. Yellowgreen radiation of 5700 Š wavelength from Hg vapor lamp 15 or white light including yellow-green light projected through window 16 and filter 18 or alternatively incident on the front face of the screen enhances the contrast, the screen being transparent or translucent to this radiation except where the electron beam impinges. The dark trace may be erased by U.V. radiation (3600 Š) incident on the front face of the screen (Fig. 1, not shown) or from lamp 15, variations in U.V. intensity effecting variations in image persistence. Either the U.V. radiation or the contrast enhancing radiation may be formed in a composite screen, with respectively a green emitting phosphor layer e.g. Cu doped ZnS or U.V. emitting Pb doped barium silicate on the non-displayed screen face. Two electron beams are employed with the composite screens, the higher energy beam penetrating to the calcium fluoride layer. The display may be viewed directly or be projected. The oxygen doping may occur before or after the screen is deposited, by heating in air. Ground particles of the screen material may be settled through a binder or the material may be evaporated on to the C.R.T. face.
