IPC: B23B31/12
Filed: 1916-02-08
Abstract: 102,180. Williamson, G. Feb. 8, 1916. Chucks; drilling; turning.-A self-centering device, described with reference to chucks of the transversely-oscillating jaw type, is stated to be applicable also for use in centring-apparatus such as is described in Specification 9494/09, the jaws in such cases being provided with rollers or the like to engage the work. A ring 2 is rotated on the body by a pivotal connexion at 5 to a nut 4 on a screw 6 let into the body and provided with a ball thrust bearing. Carriers 10 pivoted to the body at 11 have a pivotal connexion at 12 to the ring 2 and at 16 to the jaws. The jaws may have a series of recesses 15 of varying curvature or other special shapes, and be turned about the pivots to bring the required surfaces into operative position. The jaws may be provided with supplementary gripping-devices, such as plungers or dogs, and may be maintained radial by pins 17 engaging slots 18. In a modification, the jaws pass through radial slits in a loose-ring.

Abstract: 906,299. Powder distributers. VAN DER LELY N.V., C. Jan. 19, 1959 [March 17, 1958], No. 1908/59. Class 6(1). A machine for spreading granular material with the aid of a rotary spreading member 10 is converted for spreading liquid by removing the hopper 52 for granular material and replacing it with a hopper 13 for carrying liquid and means for feeding the liquid to the rotary spreading member, As shown the machine comprises a tubular frame 1 arranged to be carried by the three point linkage of a tractor, the member 10 being driven from the tractor power shaft through a gear box 11. Liquid is fed through a pipe 16 provided with a valve 18 operated by a lever 20. A stirrer 34 is driven from the shaft 9 of the member 10 by means of a clean clutch comprising a boss 39 with two projecting pins which engages a U-shaped member on the shaft 35 of the stirrer 34. For use as a powder distributer the hopper 13 and pipe assembly are removed and replaced by a hopper 52 provided with an agitator 72 formed with a bayonet coupling 73 which engages on the pins of the boss 39. The lower side of the container 52 is formed with a portion 54 and an adjustable ring 55 which bears on the member 10. The ring 55 is provided with three openings. The size of the openings is adjusted by means of plates connected to an adjustable annulus 67 which surrounds the ring 55.

Abstract: 448,678. Centrifugal switches. SINGER MANUFACTURING CO., Elizabeth, New Jersey, U.S.A. Jan. 22, 1936, No. 2018. Convention date, May 14, 1935. [Class 38 (v)] Springs, arrangement and disposition of.-A centrifugal switch for cutting out the starting winding of a singlephase A.C. motor when the motor comes up to speed comprises a baseplate 9 mounted on pillars 8 on the inside of the motor end-bonnet 2, a lever 19, Fig. 9, fulerumed at one end in notches formed in a pair of ears 13 projecting from the base, the lever having a clearance aperture 20 for the motor shaft 5, a U-shaped lever 28, Fig. 8, fulcrumed at its ends 27 in notches formed in another pair of ears 14 projecting from the base, an endwise spring- expansible thrust member 22 with its opposite ends engaging notches 21, 31 in the levers 19 and 28 respectively, and a movable contactmember 30 carried by the lever 28 and normally bridging fixed contacts 11 in the circuit of the starting winding. A spring 25 on a fixed pin 24 passing through a lug 23 on the lever 19 tends to move this lever away from the base, but when the motor is stationary or running at low speeds this movement is prevented by a spring 41 which presses a flanged collar 39 slidably mounted on the motor shaft 5 against projections 26 on the lever 19. When the motor comes up to speed, weights 36 on levers having inwardly-extending arms 37 engaging a groove 38 in the collar 39 move outwards by centrifugal action, and the collar is moved to the left against the action of the spring 41. The spring 25 then moves the end of the lever 19 to the left, compressing the spring of the thrust member 22, until the latter passes over a dead centre and completes the opening of the circuit with a snap-action.

The process of the parent Specification, in which a styryl dye masking image is produced in the magenta coloured layer of an exposed multilayer element comprising a base and superimposed thereon differently-sensitized silver halide layers containing respectively a cyan colour former which does not react with aldehydes to give coloured compounds, a magenta colour former which contains in its molecular structure a reactive methylene group, and a yellow colour former which does not react with aldehydes to give coloured compounds, by colour developing and subsequently treating the element with an aldehyde or functional derivative thereof containing at least one auxochromic group to combine with unused magenta colour former and produce the styryl mask, is modified by use, instead of an anil as functional derivative of an aldehyde to produce the styryl mask, of an aqueous solution of an anil containing an excess of either the aldehyde or the amine component of such anil, and, optionally, the element may be after-treated with a substance such as sodium nitrite or formaldehyde capable of releasing the free aldehyde from the anil. These anil solutions have improved stability, and, together with the after-treatment which is believed to release nascent and highly-reactive aldehyde from the anil which is absorbed in the element, assist in producing styryl masks of constant intensity in long lengths of film. Negative, reversal positive, or duplicate negative material may be so treated. Two examples are directed to negative development and use (1) p - (omega: omega<SP>1</SP> - dicyanodiethyl) aminobenzal-anil-3-sulphonic acid with a large excess of metanilic acid in sodium carbonate solution, followed, after rinsing the material, with after - treatment by immersion in 1 per cent formaldehyde ; (2) p - - (N - sulphoethyl - N - methylamino)-benzal-anil with a large excess of p-(N- sulphoethyl - N - methyl - amino) - benzaldehyde. Other anil mixtures are quoted. Specifications 465,823 and 486,848 also are referred to.

Abstract: 620,859. Velocity-modulated tubes. WEST. INGHOUSE ELECTRIC INTERNATIONAL CO. Jan. 27, 1947, No. 2476. Convention date, June 26, 1942. [Class 39 (i)] A velocity modulation device in which the electron flow is radially inwards from a circumferential cathode consists generally of concentric cylinders 11, 12, 13. Outer cylinder 11 contains an annular cathode 20 heated by an annular filament coil 19 connected in segments across bus-bars 17. Walls 14, 27, 15 define two concentric annular resonators. Washerlike plates 23 define a field-free space 22 bounded by an outer and inner ring of grids 33. The electrons are finally collected by the central electrode comprising a plurality of pyramidal cavities 38, a cooling medium circulating through inlet and outlet pipes 40, 39. To make provision for tuning, the resonator walls 14, 15 are tapered and have corrugations parallel to the axis to render them flexible and resilient. The outer wall 14 is encircled by a band 62 which can be moved axially by an adjustment screw device. As it moves inwards, wall 14 is compressed, reducing the outer grid gap 24, the wall expanding again as band 62 is moved outwards. A similar band 64 engages the inner wall 15 to vary grid gap 25. A simpler modification without the tuning means is also described (Fig. 2, not shown).

Abstract: 1,165,802. Rifle grenades. INDUSTRIEWERKE KARLSRUHE A.G. 18 Jan., 1967 [22 March, 1966], No. 2583/67. Heading F3A. Rifle grenade comprising a warhead 2 containing a propellant charge 25, and a tail tube 3 releasably coupled to the warhead through a fracturable shank 6 of a piston 5 formed with a striker 4 for igniting a detonating cartridge 21. On launching the grenade, the gas pressure produced on ignition of a firing charge in a rifle drives the piston forwards to fracture the shank and release the tail tube, the continued displacement of the piston causing the striker to ignite the detonating cartridge and thereby the propellant charge. Part of the gases from the rifle pass through tangential nozzles formed in an end plate 15 of the tail tube and impart spin to the grenade. The combustion gases from the propellant charge impinge upon the plate 15 and facilitate separation of the warhead and the tail tube.
