Title: Improvements in filter elements
Inventor: STOKES EDWARD ARTHUR
IPC: B01D29/21
Filed: 1954-04-21
Abstract: 764,702. Filters. VOKES, Ltd. April 19, 1955 [April 21, 1954], No. 11554/54. Class 46. [Also in-Group XXVIII] A filter element of somewhat self-supporting permeable material e.g. paper is formed by first folding a sheet of the paper zig-zag fashion along the parallel broken lines shown in Fig. 2 then folding the pleats so formed zig-zag fashion along lines A to J substantially normal to the first fold lines whereby the latter are converted from parallel straight lines to parallel zig-zag lines 2 to 9. The pleats of the element so formed are strengthened by the folds transverse to their depth and are maintained open as shown in Fig. 1. The element is sealed at its periphery into a casing. In a modification the second zig-zag folding is effected along a series of alternately inclined straight lines substantially but not precisely normal to the first set of lines.

IPC: B63B9/06
Abstract: 115,664. Stroyer, J. P. R. N. May 11. 1917. Moulds for building. - Reinforced concrete vessels are cast with the bottom and side; in a horizontal position, the sides being subsequently raised into final position when the concrete is set. The bottom a of the vessel, is cast on sectional mould panels d supported by wedges e on piers f. The sides and ends are formed on detachable hinged d mould-panel sections g which are subsequently raised. The metal reinforcement projects from the concrete, preferably in loop form p, so that when the sides and ends are raised the loops register; longitudinal rods n are then passed through the loops and the whole embedded in bonding concrete. The bottom mould-panel can be removed in sections and the concrete treated by painting, asphalting, or tarring, if desired. The vessel is then lowered on to launching trolleys s on rails t on a sloping slipway.

Title: Improvements in or relating to tool holders for lathes and like machine tools
IPC: B23B27/06
Filed: 1945-05-07
Abstract: 600,080. Tool-holders. JACOBS, M. V. May 7, 1945, No. 11660. [Class 83 (iii)] A tool-holder for lathes or the like comprises a shank portion and a socket for holding a comparatively short bar-like cutting tool and is characterized in that the socket comprises an open channel the walls of which are arranged so that the longitudinal axis of the cutting tool is both inclined to a plane tangential to the surface of revolution of the work and to a plane at right angles to the latter both planes being  considered passing through the point of contact of the tool and work, and clamping means associated with the channel. The shank portion 22, Fig. 5, of the tool-holder is adapted to be held in a tool post so that the tool 10, which comprises a short length of polygonal or round section tool steel, is presented to the work 12 at an inclination to a plane 14, Fig. 4, at right angles to the work and either tangentially, or, at a small angle to, the tangent at the point of contact of the tool. The tool is held in this position by means of a clamping device which may comprise a conical clamping bit 26, Fig. 7, with a, tool gripping recess 28 and a threaded end 27 adapted to be drawn into a similarly shaped recess in the offset end 23 of the shank. The tool may be located to give it the desired front and side cutting angles either by the clamping device itself or by the adjacent faces of the groove 24 provided in the shank. Alternative clamping means including a wedgeheaded bolt bearing on one face of the tool, and a rotatable bolt with an eccentric piece engaging a side-face are described. The shank may also be formed of circular section 45, Fig. 11, rotatable with a boss to adjust the inclination of the tool relative to a holder 41 for the shank. The swivelling portion has two flat faces on either face of which may be secured the tool-carrying clamping means 34. An eccentric boss with a slot 35 and screw 37 provides an adjustable clamping means, and similar tool gripping means to that described above is used for actually securing the tool in the adjustable portion. The holder 41 may be provided with a removable cover 43 which serves to clamp the shank 45 when secured in a tool post. According to the Provisional Specification the shank may have its longitudinal axis tilted by using a known tilting slipper arrangement and the shank may be tapered or screw-threaded.

Title: Improvements relating to processes and apparatus for continuous tempering by high frequency
IPC: H05B6/06
Filed: 1946-04-16
Abstract: 610,771. Induction heating. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. April 16, 1946, No. 11660. Convention date, Sept. 12, 1942. [Class 39(iii)] [Also in Group XXXV] The heating of an article of uniform cross-section by its continuous advance through a high frequency furnace is automatically regulated by the automatic regulation of the speed of the motor feeding the article forward, this being effected by the variations of the intensity of the current traversing the furnace inductor. In the preferred apparatus Fig. 4, the current I passing through inductor winding B creates a potential across impedance Z which is rectified negatively by V and collected at terminals of resistance Rd shunted across condenser Cd. The rectified potential which is proportional to I is applied to the grid of valve T which is polarised by the cathode by potentiometer Pot. Valve T is in series with field winding of shunt motor M which drives treated article P by milled rollers. Finally article P is quenched by jets j below screen e. If the temperature of the article leaving the furnace diminishes I will be reduced, together with the degree of polarization of valve T, the motor field current will increase and the motor speed will be reduced resulting in greater heating of the article. Similarly an increase in the article temperature produces an increase in the motor speed. Specification 617,593, [Group XXXV], is referred to.

Abstract: <PICT:0686259/III/1> A coating of powder is formed on a surface, e.g. a phosphor coating on a fluorescent screen, by floating discrete particles of a water-repellent powder (or one made water-repellent) on a liquid carrier medium to form a powder layer, exerting lateral pressure on the floating powder to form a compact aggregation and thereafter transferring the compacted layer to the surface to be coated.  The compression caused by lateral pressure may be released by about one-tenth, while the surface to be coated may be raised through the liquid medium and then dried.  The powder particles may be rendered water-repellent by treatment with aluminium naphthenate, or various stearates or wth a mixture of methyl chlorosilanes comprising about 30 mol per cent dimethyl dichlorosilane and about 70 mol per cent methyl trichlorosilane in amount of 0.1 to 6 per cent by weight of the powder particles.

Abstract: 1,249,921. High pressure testing of tubes. SCHLOEMANN A.G. March 10, 1969 [April 9, 1968], No. 12436/69. Heading G1S. A rotary press for testing tubes under high internal pressures comprises a main driving shaft 7 journalled in a fixed platen 2 and an axially movable platen 3, the shaft driving testing head carriers 9, 11 provided with tube testing heads 13 which are axially displaceable by stationary cams 15, and a pressure raiser 19 having a differential piston 30 for producing the high testing pressures, the pressure raiser being rotatable with the main shaft. The platen 3 is moved axially by a motor 4 via a rack 6 and a pinion 5, whilst a spur gear 26 secured to the shaft 7 rotates the shaft through a drive (not shown). Couplings 10 transmit the drive from the carrier 9 to the carrier 11 and rollers 14 engaging the cams 15 provide the axial movement of the heads 13 so that the heads engage the opposite ends of a tube to be tested. A cylinder 19a rotates with the shaft 7 and water for filling the tubes under test is conveyed to the heads 13 via a fixed inlet 20, a rotating duct 37 and a bore 40. Water under pressure is fed to the piston through a fixed inlet 21 and a tube 45 so that a high internal pressure is applied to the tube under test by the piston rod 31 acting on the water present in a bore 32 and a conduit 33. The pressure raiser 19 only operates when a tube to be tested is present.
