Patent GB-500190-A (GB)
Title: Improvements in or relating to method of separating materials and fluid separating mediums therefor
IPC: B03B5/44
Filed: 1937-07-27
Abstract: 500,190. Wet - separating. JACKSON, L. MELLERSH-. (Jeffrey Manufacturing Co.) July 27, 1937, No. 20784. [Class 82 (ii)] Gravity separation of materials, e.g. coal, is carried out in a separating medium composed of finely divided argillaceous material held in suspension in water by a relatively small amount of a deflocculating agent such as sodium silicate or aluminate. A coarser material such as quartz sand, silica sand, crushed ganister, &c. is preferably also present. The argillaceous material may be clay, e.g. bentonite, or shale, silt, fireclay, &c. The suspension is preferably allowed to stand for a time, e.g. for at least a day, after the addition of the deflocculating agent. The usual proportion of the deflocculating agent is between 0À6 and 1 per cent by weight of the argillaceous material, and, in the case of suspensions of clay without sand, this agent also acts to reduce the viscosity of the medium. The composition of the medium is preferably chosen so as to reduce to a minimum the amount of solids removed with the washed material, this factor being tested by immersing a glass or cardboard plate in the suspension and weighing it after removal. Specifications 470,062 and 500,043 are referred to. Reference has been directed by the Comptroller to Specification 130,972, [Class 82 (ii)].

Title: Improvements in and relating to cutting apparatus for sheet material
IPC: C03B33/04
Filed: 1936-07-28
Abstract: 478,685. Cutting glass. KLAGES, N. H. July 28, 1936, No. 20858. [Class 56] In a machine for cutting sheet glass in which a tool head is guided through the entire circumference of a ring-like template with the aid of a pair of rollers engaging one edge and a single roller engaging the other edge of the template, ,the rollers are held in contact with the edges resiliently. Means are provided to limit the pressure of the tool on the glass. Two machines are described. Machine with movable table, Figs. 2, 5, and 9. The sheet is carried by a table 12 which is raised into contact with the scoring tool by depressing a lever 37 provided with a latch 39 which limits the extent of depression. The lever is coupled to the table-controlling levers through a spring 32 the tension of which is adjustable. The maximum pressure between the work and the tool is thus pre-determined and does not depend on the operator. The template 53 is adjustably carried by arms such as 57. The assembly 42 is carried by a jointed and swivelling arm, the tool 60 itself being allowed to castor. It is held to the template by means of a grooved bar 49 working between guide rollers 48 and resiliently held to the tool assembly by springs 54. This bar carries a bracket, 51 carrying a pair of guide rollers 52 for engaging the outer periphery of the template, the inner periphery of which is engaged by a single roller 55. The cutter is fed with oil from a reservoir 68. Machine with fixed table, Fig. 7. In this case the tool is carried by a block 77 which is movable up and down in a housing 73 and is urged downwardly by a spring 85 acting through a rod 86 and supporting member 79. The tension of the spring is adjustable. The position of the tool relatively to the main part of the head is adjustable by a screw 83. Design of template. As shown in Fig. 9, where the template is sharply curved the outer edge is given the contour indicated by the dotted line to ensure that the leading roller 52 shall remain in contact with the template and so keep the axis a-b of the cutter at right-angles to the line c of the cut.

Patent GB-1220116-A (GB)
Title: Automatic firearm
IPC: F41A3/82
Filed: 1968-05-02
Abstract: 1,220,116. Automatic firearm. WERKZEUGMASCHINENFABRIK OERLIKON BUHRLE & K.G. 2 May, 1968 [12 May, 1967; 19 April, 1968], No. 20965/68. Heading F3C. An automatic firearm comprises a breech assembly having a breech block part which is lockable in a firing position by locking members under the action of a control member (Figs. 1, 2, not shown). The control member is connected through a breech casing to two spring loaded sleeves 8, one at each side of the firearm. On firing of the firearm the control member and hence the sleeves 8 begin to recoil against their spring loading, the recoil, however, being limited by two members 26, 33 each of which forms a stop for an extension 16 of a respective sleeve such that the control member is still in a breech block part locking position. Release rods 50 are then actuated by gas bled from the firearm barrel to urge the members 26, 33 away from the extensions 16 and thus allow the sleeves 8 and control member to recoil to unlock the locking members and hence the breech block part. In the construction shown members 26, 33 each comprise two parts housed in a guided support a spring being interposed therebetween so that the part 26 is urged outwardly of the support, the part 33 being in engagement with the breech casing. The release rods 50 actuate the members 26, 33 through engagement with extensions 48 of levers 44, the levers 44 in turn co-operating with arms 28 connected to the part 26. The shock produced by the engagement of the extensions 16 with members 26, 33 is attenuated by providing the supports 20 at their rearward ends with spring loaded sleeves, the heads 36 of which bear against pins 41 mounted in the breech casing. The firearm is further provided with a spring loaded cocking mechanism 62, 63, 66, 67. Rearward movement of the cocking mechanism against its spring loading after the mechanism has been unlocked manually rotates a lever 56 urging a carriage forwardly against a spring loading and thus rotating a further lever 56. These levers 56 are connected by shafts 45 to levers 44 and hence rotation of levers 56 cause, through levers 44, retraction of members 26, 33. A dog 67 of the cocking mechanism then urges the sleeves 8 rearwardly such that the breech assembly may be cocked. In a further embodiment (Fig. 9, not shown) the members which engage the extensions of the sleeves comprise levers each of which forms a part of a spring loaded toggle linkage.

Title: Improvements in electric discharge tubes
IPC: H01J19/68
Filed: 1924-09-05
Abstract: 231,821. McCullough, F. S. April 3, 1924, [Convention date]. Vacuum tubes. - A very small quantity of helium is introduced into a highlyevacuated tube by liberation from the cathode 7, which may comprise a molybdenum or other wire coated with thorium or uranium nitrate by repeatedly dipping in a solution thereof and drying. The envelope consists of a metal portion 5, forming the anode, sealed to a glass portion 6 through which are also sealed the leads to the cathode 7 and grid 9. After preliminary exhaustion, an oven is lowered around the entire tube and the tube baked at a high temperature. While the tube is still on the pump, a heating-coil a is placed around the metal part 5 of the tube and the temperature of the metal raised to 800‹ or 1000‹ C., by which means the metal shell and the cathode are degasified. After sealing off, a current is passed through the filament and increased until the filament attains a dull red heat, which is maintained for some time for ageing the filament. During the ageing process a minute amount of helium is evolved from the heated cathode. Reference has been directed by the Comptroller to Specifications 148,132, 164,924, 188,706 and 207,514.

Filed: 1952-08-25
Abstract: 721,330. Ammunition cartridges. DELEMOTTE, E. Aug. 25, 1952 [April 12, 1952], No. 21320/52. Class 9(1). An undershot wad for a sporting cartridge comprises a resilient body 3, e.g. cork in a thin cylindrical casing 1, the upper part of the casing being adapted to hold part of the shot charge to guide it in the barrel and reduce friction between the shot and the barrel and also to reduce shot dispersion. The casing 1 extends beyond the lower end of the body 3 to form an expansion chamber for the propellant gases. This chamber may be closed by a disc which ruptures at a given pressure. In Fig. 1 the body 3 has a frusto-conical end 5 leaving an annular space 6 between the end 5 and the casing 1 as the expansion chamber. The body 3 may fit fairly loosely in the casing 1, which is then closed at the rear by a thick disc provided with a central aperture. In another modification, Fig. 4, the casing 1 has an integral base closure 12, which may be flat or convex, provided with an aperture 11 to admit the gases to the chamber 4. Fig. 6 shows a cylindrical disc 7 of fatimpregnated felt or red paraffin, interposed between the resilient body 3 and an overlying gas-tight washer 9. Apertures 8 in the casing 1 register with the disc 7 and the frusto-conical part 5 of the resilient body extends beyond the casing 1, so that when the wad is within a cartridge the part 5 enters the powder charge. On firing the cartridge lubricant from the disc 7 escapes through the apertures 8. The arrangement of Fig. 4 may be modified by shortening the casing 1 and fitting within it a tube holding the resilient body 3, this tube being of smaller diameter than the minimum diameter of the barrel. The body 3 may be cork filled with neoprene and the casing 1 may be cardboard coated with lubricant.

Abstract: 372,176. Echo-sounding apparatus. MARTI, P. A. D., Montbeliard, Doubs, France. July 27, 1931, No. 21431. Convention date, Aug. 4, 1930. [Class 118 (ii).] Optical indicating means for use with echosounding apparatus comprises a device in which a luminous ray sweeps across a screen, the ray being narrow in the direction of sweeping and long in the perpendicular direction, a small part only of the ray normally impinging on the screen, but on the emission of the sound and on the return of the echo a greater part of the ray is allowed to fall on the screen. Light from a lamp 1 passes through a lens 2, a slit 3 in a screen 4 and a lens 6 on to a screen 5. The ray is caused to sweep across the screen 5 by the interposition of a rotating mirror or by other known means. All but a small portion of the slit 3 is normally obscured by a shutter 7 pivoted at 9, but on the emission of a sound and on the return of the echo the shutter swings aside to expose all the slit. The distance between the resulting two light spots is a measure of the required depth. In a modification, a circular screen 5 is provided.

Abstract: 1504533 Dynamo-electric machine windings GENERAL ELECTRIC CO 20 May 1975 [20 May 1974] 21498/75 Heading H2A Rotor losses in an induction motor are reduced by eliminating induced currents corresponding to a particular harmonic of the stator field, this being achieved by interconnecting the rotor conductors to form several different cages, adjacent conductors in each cage being spaced apart by twice the pole pitch of the harmonic concerned. The rotor shown has three cages corresponding respectively to conductors 126, 127 and 128, there being a single short circuit ring 122 at one end of the rotor and three rings 123, 124 and 125 at the other end. The rotor is intended for use in a 6 pole motor, the adjacent conductors of each cage, e.g. adjacent conductors 126, being spaced apart by 40 degrees, i.e. twice the pole pitch for the third harmonic, so no third harmonic currents will flow in the rotor. In a modification, Figs. 15 to 19 (not shown), also for use in a 6 pole motor, the rotor again has three cages but there are two short circuit rings at each end of the rotor. The rotor constructions disclosed are stated to increase motor efficiency and to increase low speed stability in induction motors wherein speed variation may be achieved by varying the number of stator winding turns connected across the supply.
