Filed: 1938-01-21
Abstract: 514,350. Separating granular materials. BIERBRAUER, E., and METALLGES. AKT.- GES. Jan. 21, 1938, Nos. 2106, 2107 and 2108. Void. Convention dates, Jan. 21, 1937, March 4, 1937 and Sept. 25, 1937. [Class 82 (ii)] The constituents of a granular mixture, for example, coal and shale, or minerals and gangue, are separated by bringing the mixture into contact with an adhesive mass, generally with the aid of yielding pressure, such as by means of spongy rubber, some of the constituents dropping off first and being thus separated from the remainder. The adhesive mass may be, for example, tar, pitch, bitumen, asphalt, resin, oil, wax, or ice. The mixture to be separated may be pre-treated with water, organic liquids, or other agents, to increase the difference in adhesiveness of the constituents, and the adhesive mass may be regenerated by treatment with agents such as organic liquids or aqueous emulsions. In the apparatus shown in Fig. 1, the mixture is supplied through a hopper c to a roller b coated with spongy rubber or the like b<1> and is carried thereby against an adhesive mass a<1 >on a roller on which is counterweighted or otherwise mounted so that the pressure may be regulated. The non-adhering grains drop into a trough k, while the adhering grains are removed by a stripper g to a trough h. An agent for regenerating the mass a<1> may be applied by a roller o. In the form shown in Fig. 4, a rapidly moving endless band 1 carries an adhesive mass 1a, and the material fed through a hopper 4 is carried round the roller 2, the non-adhering grains falling into a trough 5, and the adhering grains being stripped into a trough 6.

Abstract: 1,224,604. Colour television tubes. THOMSON-CSF. 16 Jan., 1969 [17 Jan., 1968], No. 2705/69. Heading HID. In a colour television tube comprising a focusing grid of parallel wires 5 clamped between opposing edges of mating envelope portions 1 and 2, a jig arrangement, formed on an opposing edge of at least one of the envelope portions and comprising a series of grooves 8 formed for example in a thin strip 7 of quick-drying cement (as shown) or in the edge of the envelope itself, Fig. 12 (not shown), is provided to accurately locate the grid wires whilst they are sealed into the joint between the mating faceplate and bulb envelope portions. The quick-drying cement, e.g. a mixture of alumina and sodium or potassium silicate, is unresponsive to the heat treatment involved in sealing the tube and is spread in a band a few millimetres wide and a few tenths of a millimetre thick on the edge 4 of the faceplate 2. A master grid die, manufactured to tight tolerances, is placed in correct register with the phosphor strips of the screen and pressed into the cement to leave its imprint 8 therein. The grid is prepared by stretching parallel wire over a frame, Fig. 9 (not shown), locating them in the grooves of the die and sealing the grid wires in the joint between faceplate and bulb by coating the opposing edges with a material which melts upon heating the assembly in an oven to about 450‹ C. Another method of forming the grooves in the cement is by the displacement of a threaded rod in contact with the edge 4. Alternatively the grooves may be formed in the wall of the envelope portion itself by etching with hydrofluoric acid. The grids produced may be of variable or uniform pitch. '

To produce cigars or bunches with partially or wholly coned or spherical heads, the projecting glued end 16 of a wrapper (or binder) leaf 6 being wrapped about a bunch (or filler) 14 by rolling of the latter over a table 7 is appropriately stretched by movement of a table part 9. As shown applied to the suction table 7 of a perforated rolling apron 2 on which the leaf 6 is automatically deposited from a cutting matrix by a conveyer (not shown), the part 9 has a separate suction connection 10 and is operatively rotated against the loading of a spring 11 by a pin 12 on the reciprocating apron frame 4 engaging a pin 13, the end 16 being thus deposited neatly on the coned or spherical bunch end and finally smoothed down by a block 17. The finished cigar is trimmed at its smoking end and, optionally, at its head end to truncate the latter. The apron 2 may have the same width as the table 7, when the part 9 partially underlies the apron or may lie at the side of the table 7 and perhaps have a translatory as well as a rotary movement. In a modification, the leaf 6 lies directly on suction table over which a roller set replacing the apron 2 is reciprocated.

Patent GB-595147-A (GB)
Title: Improvements in and relating to hydraulic piston type control valves
IPC: F15B13/01
Filed: 1945-02-05
Abstract: 595,147. Valves; hydraulic presses. TOWLER, J. M., and TOWLER, F. H. Feb. 5, 1945, No. 2805. [Classes 69 (ii) and 135] An hydraulic control valve of the piston type is movable against loading means by manuallyoperable means to supply pressure liquid to a press or other hydraulic cylinder and when the pressure in the cylinder attains a predetermined value or the press ram reaches a certain position the manually operable means is automatically disconnected from the valve plunger which returns to its original position under the action of the loading means. Figs. 1 and 2 show the invention applied to the piston valve described in Specification 557,340. The hand lever h is secured to a transverse shaft 12 passing into the casing g. A short lever 13 with a pin 14 engaging a groove 15 in the valve plunger b is pivotally supported at 17 on the inner end of the shaft 12 and is normally pressed towards the valve plunger by a spring plunger 18. The pin 14 is disengaged from the groove 15 to allow the loading spring 16 to return the valve to the position shown in Fig. 1 by fluid pressure acting below a plunger 21 which actuates a round-ended lever 19 rigid with the lever 13. Passages 25, 26 permit the pressure liquid to escape when the plunger 21 has completed its stroke, the magnitude of which is governed by a distance piece 24. The lever h carries a spring- urged detent 27 engaging notches in a quadrant 28. Where the release of the valve plunger is dependent upon the attainment of a predetermined pressure in the press cylinder, the latter pressure acts on a master control valve such as that described in Specification 566,240 and the master control valve controls the application of pressure to the plunger 21. Where the release of the valve plunger depends upon the position of the press ram, the supply and exhaust of pressure fluid beneath the plunger 21 is controlled by a small leveractuated valve supplied from the press supply pipe and operated by a tappet on the press ram. To prevent the valve plunger from sticking when released, it is given an initial push by a further plunger to which pressure liquid is admitted in parallel with the supply to the plunger 21. The latter, however, is more lightly loaded and consequently operates first. The invention is equally applicable to valves controlling single acting devices. Specification 573,440 is referred to in the Provisional Specification.

Title: Improvements in or relating to gear bore and tooth-flank concentricizing methods andmachines
Inventor: KLOMP ALFRED WALTER
IPC: B23F19/05
Filed: 1960-01-26
Abstract: 902,540. Gear-finishing; reaming; milling-cutters; machine-tool details. PROCESS GEAR & MACHINE CO. Jan. 26, 1960, No. 2835/60. Classes 83(2) and 83(3). [Also in Group XXIII] A method of producing a gear consists in machining the teeth and the bore simultaneously. A machine comprises a worksupply shoot 21, Fig. 1, a workfeed 17, a machining mechanism 16 and a discharge means 18 on a base 15 surrounded by a coolant trough 19. The machining mechanism comprises two helically-toothed bronze or castiron grinding, burnishing or shaving tools 22, 23, Figs. 2, and 8, rotated through gearing 40, 41 and an idler tool 24 surrounding a floating arbor 25 along which the gears are moved by the helical formation of the tools. The arbor has grooves tapering in depth to receive abrasive blocks which are advanced intermittently up the grooves to allow for wear. Spent abrasive is assisted in escaping by helical grooves 25e in the arbor. In a modification, the arbor is formed as a reamer. The wheel 22 has end caps 26 and is mounted on a shaft 30, 27 which extends therethrough. The shaft has a tongue 30a to engage one of the caps 26 and can be rotated by a hand-grip 30b after slackening a clamp 33 to enable the wheel to be meshed correctly with a work-gear. By removing the clamp 33, the shaft 30, 27 may be withdrawn and the wheel removed. Supports 35, 37 for the wheel 23 are mounted on a laterallyadjustable slide 36, and the upper wheel 24 is supported on an angularly-adjustable arm, to enable gears of different diameters to be accommodated. Machined gears pass over a guide roller 57 on to a reduced portion 25b of the arbor, and are then engaged by a freely-moving resilient belt 58. The belt may be driven but is normally moved by the forward motion of the gears, the arbor being positioned initially by a series of dummy gears. The work-feeding means are carried on a slide 70 advanced through rack-and-pinion gearing 71, 72 by a hand wheel 74, Fig. 9, until adjustable stops 75, 76 engage and a switch 109 is actuated to start a machine cycle. A slide 77 is movable by a fluid-pressure device 79 on the slide 70 to move a tube 81 and a resiliently-advanced rod 84 to advance a blank from the shoot 21 on to the arbor. At the same time, a slide 89 is moved by fluid-pressure means 90 to advance rods 87 which move the abrasive blocks along their grooves in the arbor. The amount of abrasive feed is determined by a time delay relay of the dashpot type. When the abrasive elements have been used to their limit, a member 121 actuates a switch 122 to illuminate a warning light, to return the slides to their original positions and to stop all the motors, namely, an hydraulic pump motor, a tool-drive motor, a coolant pump motor, and a hopper vibrating motor.
