Title: Apparatus for unstacking bottle crates or the like
IPC: B65G59/06
Filed: 1955-04-12
Abstract: 823,148. Unpacking. TOLLEY, B. G. April 18, 1956 [April 12, 1955], No. 10559/55. Class 94(1). A machine for unstacking bottle crates comprises a track 2 along which stacks of crates are moved by a chain conveyer 4 and a framework 7 which is reciprocable vertically in guides 6 by crank and connecting-rod mechanism 8-11, the shaft 12 of which is driven through a one-revolution clutch 13 by a motor 14. The frame 7 carries rotatable shafts 17 having fingers 18 at their ends adapted to engage under the top rails of the second and higher crates in each stack. Arms 20 on the shafts are coupled together by a link 19 and an extension 21 of the uppermost shaft is formed with an arm 22 carrying a roller 23 arranged to engage a spring-loaded plate 25, Fig. 4, pivoted to a fixed bracket 24. On the upward movement of the frame 7, the roller rides over the front face of the plate so that the shafts are rocked to extend the fingers, and towards the end of the downward movement of the frame the fingers ride down the sides of the crates and are thus retracted and the roller passes behind the plate. The stacks of crates are arrested by a stop 27 and are released in succession by a spring-loaded lever 28 actuated by a pivoted pusher 30 coupled to a link 31 which is connected by linkage 35 to a spring- loaded trip member 34 engageable by the second crate in each stack. Assuming that a stack has been released from the stop, it moves into engagement with a spring-loaded lever 36 which operates through linkage 37 to engage the clutch 13 and cause the frame 7 to descend and rise. At the commencement of the upward movement of the frame, the fingers 18 are extended to engage and lift all the crates in the stack except the lowermost one which is moved on by the conveyer into engagement with a second spring-loaded lever 38 which operates through linkage 39 to re-engage the clutch 13, thus causing the frame 7 to descend and rise once again leaving the lowermost crate to be moved on by the conveyer. These operations are repeated until all the crates have been separated in succession from the stack, the levers 36 and 38 being periodically depressed clear of the lowermost crate by an abutment 44 on the frame 7 and a lever 42 actuated by a spring-loaded plunger 43 which in turn is actuated by an abutment on the frame. When the stack has been reduced to a single crate, the trip member 34 is released and operates to swing the link 31 to a position such that its upper end 32 is engaged by a lug 33 on the frame 7 as the latter descends, the pusher 30 being thus operated to release the next stack from the stop 27.

Abstract: 560,689. Cathode-ray tubes. COSSOR, Ltd., A. C., JOFEH, L., and WILLIAMS, B. C. FLEMING-. June 26, 1940, Nos. 10902/40 and 5927/41. [Class 39 (i)] In electron beam deflection valves, the deflecting plates P1, P2 to which the alternating deflecting potentials are applied, are curved and have applied to them steady biassing potentials to cause the beam to follow the curved path between them. The plates act also to focus the beam, and in the arrangement shown the length of the plates is such as to focus the beam finely on the edge F1 of a target electrode T1 followed by a collector target T2. The target electrodes are preferably of U-shape to suppress secondary emission, and the sides of the target T1 are inclined away from the path of the beam. Axial adjustment of the focus of the beam is provided by an electrode S, whose primary purpose is to prevent secondary emission from the targets reaching the deflector plates. In an alternative arrangement, the output may be taken from plates, similarly shaped and disposed on each side of the beam, in conjunction with a pair of targets to supply another output circuit. The plates may be subdivided with additional focussing devices between the sections. The beam is preferably of ribbon form generated by a part cylindrical cathode C, shield G and slit anode A.

Abstract: 490,081. Fluid-pressure servomotorcontrol systems. LAIDLAW, A. B. S. April 16, 1937, No. 10937. [Class 135] In a fuel-burning system the rate of combus. tion is maintained constant under control of a thermostat C which regulates a fuel leak-off valve L. The thermostat may be replaced by a pressure or speed device. Fuel under pressure from a pipe F passes to a burner pipe E, being regulated by a piston A. A relief valve B, constructed in accordance with Specification 437,327 controls the quantity of fuel passing to an overflow O. When the combustion temperature is below that required, the thermostat C opens valve L and fluid will flow from the upper piston chamber of B. The reduction in pressure is transmitted to A and causes an increased flow of fuel through E. The valve B has upper and lower pistons of different areas, pressed apart by a spring, and a conduit 10 embodying a needle valve leading to the chamber containing the upper piston.

Filed: 1954-04-20
Abstract: 761,165. Pile fabric looms. BIGELOWSANFORD CARPET CO., Inc. April 20, 1954 [May 4, 1953], No. 11313/54. Classes 142 (2) and 142 (4). Pile fabric having loops of individuallycontrolled heights (e.g. from three-sixteenths to three-quarter inch in steps of one-sixteenth) is produced by holding pile warp yarns 1, Fig. 5, on hooks 86 whilst a binder weft shot B is inserted by a needle 54 and beaten up by a reed 172. The warp 1 is lifted by its heddle 55 to the top shed line; the hooks 86 descend between the yarns, having first been tilted anti-clockwise from the vertical attitude shown to bring their tines 88 horizontal ; they are then shogged sideways, returned to vertical, and raised, whereby each yarn 1 is lifted an amount depending on the distance of the tine below the hook bar 84. The hooks are disengaged from the finished loops by tilting again. In one embodiment a separate hook bar is used for each row of loops, the bars being carried by a conveyer chain and manipulated by clasping arms indentical with Axminster loom mechanism; additional cam-operated linkage is provided to tilt and shog the hook bars. In another embodiment, Fig. 19, a hook bar 180 permanently mounted on arms 182 has hooks 200 projected selected amounts by bringing the bar against a jacquard pattern chain 201, latches being released by a cam-operated striker 226 acting on a lever 222 to allow the hooks to be fully retracted by springs and re-projected by the pattern card acting on nibs 208 of graduated lengths; the projection is determined by the longest nib that encounters a blank on the card (any longer nibs having passed through holes). The nibs may be integral with the hooks 200. Alternatively they may be on separate stop members by which the fresh setting of the hooks is pre-selected while the hooks remain retracted so as to be in alignment when they penetrate the warp sheet; as the hook bar 180 rises, the pull of the yarns withdraws the hooks from the bar until they are arrested by the pre-set stops, whereupon an additional arm 316 operates a lever 306 to lock the hooks before completion of the loop-drawing movement; the arm 226 and lever 222 are used, in this case, to lock the stop members. U.S.A. Specifications 233,290, 1,475,261 and 1,904,939 are referred to.

Abstract: 373,354. Artificial daylight lamps. CLAUDE, G., 3, Avenue de l'Opera, Paris. -(Assignee of Beck, L. L. ; 27, Stoneleigh Park, Westfield, New Jersey, and Noble, A. E. ; 46, Nassau Boulevard, Lynbrook, Long Island, New York, both in U.S.A.) April 16, 1931, No. 11327. Convention date, April 17, 1930. [Classes 75 (ii) and 75 (iv).] For the production of artificial daylight, light from neon tubes is mixed with light from mercury tubes so that the intensity wave-length curve of the resultant mixture has a maximum value corresponding approximately to a wave-length of 5500 Angstrom units, and preferably has values in the red and green portions of the spectrum substantially coinciding with those of daylight. One part of neon light may be combined with four parts of mercury light filtered through a uranium glass or other yellow screen, the proportion of the two lights being obtained by controlling the length or diameter of the tubes or the discharge current supplied. The latter may be of high voltage and low amperage or of low voltage and high amperage and the tubes may be supplied from a single source or from independent sources. The mercury tubes may be made of uranium glass and may contain one or more rare gases, the electrodes are preferably of small dimensions to avoid enlargements of the tubes, and the cathodes may be treated with an electron-emitting substance such as a metal of the alkali or alkalineearth groups or compounds thereof. The Specification describes a method of treating a nickel or copper electrode with barium peroxide. For low voltage direct current the cathodes are adapted to operate at a high temperature and may comprise a pool of alkali metal. In the form shown in Fig. 2, a mercury tube 1 is arranged along the focal line of a parabolic reflector 19 having a recessed portion 23 provided with slots 24 and engaged by a hollow cylindrical member 21 surrounding a neon tube 2. Fig. 5 shows four mercury tubes 28 and a neon tube 29 arranged inside a reflecting device 38 fitted with a diffusing prismatic member 42. The reflecting device may be fitted with a diffusing screen made of frosted or translucent glass.
