Abstract: 719,618. Cartridge-actuated tools. HOLZ, E. Oct. 13, 1950 [Oct. 14, 1949; April 8, 1950], No. 25043/50. Class 119  A device for projecting a nail or dowel into a surface by the explosion of a cartridge comprises a striker and a spring loaded hammer, the spring of the hammer being compressed by a sleeve movable and axially guided in the device on pressing the device against the surface and means is provided to prevent release of the spring until it has attained a predetermined compression. As shown a cartridge 3 is fitted in the breech portion of a barrel 1, the muzzle end of which carries a washer 11. The muzzle of the device is placed against a surface and pressure is applied to a cap 7 which slides on the barrel thus compressing a spring 15 within the cap. A pawl 14 prevents movement of a striker hammer 13 until such time as a bevelled edge 18 pushes the lower end of the panel away from a ledge on the striker support 4. The hammer 13 is then rapidly moved by the spring 15 and hits a striker 5 causing the cartridge to explode. The striker is returned to its initial position by a spring 10 A safety pin 9 prevents accidental operation of the device. In a modification, Fig. 4 (not shown), the hammer is held against the spring by three balls which, when the compression of the spring has reached the desired amount, move into a recess and release the hammer. In a further modification, Fig. 7 (not shown), the device is provided with a rotatable magazine and the compression of the firing spring is carried out in two stages under the control of a rotatable safety catch.

Title: Improvements relating to the separation of the constituents of coal washing and sludges
IPC: B03B5/14
Filed: 1938-08-27
Abstract: 518,508. Pumping water; gravity-separation apparatus; filters. WIEMER, E. Aug. 27, 1938, No. 25233. Convention date, Aug. 28, 1937. [Class 46] To separate the constituents of coalwashing or other sludge, the sludge liquid is passed under pressure into a closed space over a screen and an intermittent upward movement is given to the liquid by means of a piston, so that heavier constituents can settle and are discharged while the liquid and unseparated solid matter is passed into a sludge-settling and concentrating device from which the liquid is discharged through a filter under pulsatory pressure. In the arrangement shown coal washing water is fed from a receptacle 6 down a pipe 5 to a space above a screen 4 beneath which a piston 2 moves in a cylinder 1. The heavier solid matter settling on the screen is discharged through conduits 9, 10. Part of the pipe 5 is formed as a filter 7 through which water passes to the conduit 8 during the downstroke of the piston. During the upstroke some water returns through the conduit 8 and cleans the filter 7, but most of the water passes through the screen 4 and washes lighter solid matter over an overflow 12 into a channel 13. The screen may be in sections of different permeability and the water forced upward by the piston is distributed by baffles 16 with adjustable apertures. An outlet 14 from the channel 13 is closed by the piston 2 when in its lowest position, but when the piston moves up the mud falls into a chamber 20 fitted with grids 29, 30. During the downward movement of the piston the mud is pressed against a filter 19, through which clean water passes to an outlet 18. The mud collects at the bottom of the container 20 and is pressed by a worm 23 through an opening controlled by weighted pivoted flaps 26.

Abstract: 860,213. Electric heating elements. BALDWIN, A. W., Aug. 6, 1959 [Aug. 8, 1958; Oct. 20, 1958]. Nos. 25494/58 and 33399/58. Drawings to Specification. Class 39 (3). A heating element comprises a number of superimposed layers of a mixture of carbon and a metal having a positive temperature coefficient of residivity coated on an insulating support, for example, fibre-glass cloth, or mica flake and/or fibre-glass impregnated with a thermosetting resin. The deposits are applied by spraying or printing to discrete areas of the support and preferably joined in series by zinc strips; metal foil terminal tags may also be provided and the whole assembly enclosed in a further layer of the same material as the support. The deposit is preferably applied in six layers as a slurry of 74 parts by weight of graphite and 26 parts of finely particulate silver or nickel. Alternatively a slurry is formed by mixing together an aqueous solution of graphite and silver nitrate, the metal salt being decomposed after filtering by being baked in a graphite crucible. The individual graphite particles are thus coated with the metal and the slurry is formed by suspending the particles in alcohol, naptha or water. The overall coefficient of resistivity of the element may be either sign or zero, and the number of layers. coated on the support may be varied depending on the resistance per square desired. The heating element is suitable for use in ovens, panel heaters, as a de-icing means in aircraft and similar medium temperate equipment.

Title: Improvements in or relating to a process and apparatus for the production of unsaturated hydrocarbons
Inventor: HOWLAND ALFRED HAROLD
IPC: C07C5/48
Filed: 1954-09-03
Abstract: <PICT:0819783/IV (b)/1> A process for the conversion of substantially saturated hydrocarbons to unsaturated hydrocarbons, particularly acetylene, comprises feeding a premixed mixture of saturated hydrocarbons and molecular oxygen or air at a high rate of flow into a combustion chamber long in relation to its transverse dimension, the mixture containing the hydrocarbon and molecular oxygen in ratios substantially different from the stiochiometric ratio, igniting the mixture to effect a pyrolysis or cracking of the saturated hydrocarbon, stabilizing combustion in said zone by means of an independent disc-like flame maintained in the path of flow of said mixture to extend transversely thereof, withdrawing the hot combustion products from the chamber and cooling them.  In a preferred embodiment the combustible mixture enters a cylindrical ceramic duct 1 through an inlet A and passes to a refractory cross-piece 2 which is provided on the longitudinal axis of the duct with a cylindrical projection 3 which acts as an obstructing element against which may be projected a jet of hydrocarbon fuel from an axial nozzle 4 supplied from outside the duct by a pipe 5.  Tubes 6 and 7 adapted to be supplied with air or oxygen via pipes 8, 9 and 10 co-operate respectively with the nozzle 4 and projection 3 to provide annular ports 11 and 12 for supplying air or oxygen to the thin disc of fuel formed by the jet of fuel impinging on projection 3.  As an alternative, the air or oxygen may be supplied through the fuel nozzle and the fuel supplied through the air distributer.  The product gas which may contain 6 per cent of acetylene may be quenched in a gas turbine. Specifications 711,208 and 819,784 are referred to.

Cans C, loaded into a pocket 1 at an assembly position A of a loading apparatus and transferred with the pocket to a loading position L, are deposited in layers in a loose-bottomed crate disposed beneath the position L when a shutter 11 supporting the cans in the pocket moves from beneath them. A jack (23), Fig. 1 (not shown), supports the loose bottom of the crate (9) at the required height. In the embodiment shown there is also an intermediate position I, Fig. 2, three pockets being carried on an intermittently rotatable support 2 between the three positions. Cans are loaded at A from a rotating feed disc 5 through a gate 3 in the vertical wall of the pocket, on to a rotating table 6 situated beneath the pocket, which directs the cans to form a layer within the pocket walls. During movement of the filled pocket from position A to position I the cans are supported by a stationary plate 10. The rearward position of shutter 11 is beneath the plate 10 under the position I, and as the shutter 11 advances towards the loading position L the support 2, and hence the filled pocket 1, is carried with it by the engagement of sprung pawl (17), Fig. 4 (not shown), with a toothed member (15) of the rotatable support 2, Fig. 2. During this movement the cans are supported on the shutter. At the position L, the height of the crate bottom having been suitably adjusted by the jack, the shutter returns to position I leaving the pocket at position L and thereby depositing the cans either on to the loose bottom of the crate or on to a previously formed layer of cans. A sprung pawl (20) Fig. 4 (not shown), on a fixed member engages locking recesses (19) on the member (15) to prevent the support 2 returning with the shutter 11 to the intermediate position I.
