Abstract: 1,226,333. Plaster compositions. BPB INDUSTRIES Ltd. 22 March, 1968 [22 March, 1967], No. 13546/67. Headings C1A and C1H. Cast gypsum sheets, slabs or blocks, e.g. plasterboard with a gypsum core, contain tartaric acid as an additive to reduce " plastic flow". The acid is added in forming the water/ plaster mix, either by adding it as solution or suspension in the water or as a solid mixed with the plaster. The amount of tartaric acid used is preferably in the range 0À005-0À2% by weight, based on the dry plaster used in the mix, and the mix may be formed, cast and set under non-alkaline conditions. Setting accelerators and other conventional additives may also be used in the mix. Foaming agents may be added to the water/plaster mix, e.g. resin soap based on pine resin or " Teepol " (Registered Trade Mark) foaming agents based on sodium secondary alkyl sulphates and sodium benzene sulphonates.

Abstract: 1,226,693. Levitation furnaces. COMPAGNIE GENERALE d'ELECTRICITE. 23 Jan., 1969 [6 Feb., 1968], No. 3984/69. Heading H5H. An annular conductive mass 20 is levitated in an inductor device which includes a conductor 12 extending through the central space of the device. The conductor 12 is stated to provide a circular magnetic field which is tangential to all points on the surface of mass 20 so that it provides an electromagnetic force which is normal to all points of the surface and directed into the mass. The central conductor 12 therefore creates an artificial surface tension which will maintain an annular liquid mass 20 without any natural surface tension in cohesion. In the levitation induction furnace shown, the conductor 12 is joined at A to a conductive bowl 13 which is secured by a collar 18 to a dished metal cover 15. A return conductor 16 is joined to cover 15 and the inductor is connected to an A.C. source 10. In Fig. 3 (not shown) bowl 13 is replaced by curvilinear conductors arranged on a surface of revolution and joined to respective curvilinear conductors arranged on a surface of revolution and joined to respective curvilinear conductors arranged on a surface of revolution which replace the cover 15. The conductors are hollow and water cooled.

Abstract: 1,256,489. Laying pipes. CHISSO CORP. 16 Oct., 1970 [16 Oct., 1969], No. 49383/70. Heading F2P. [Also in Division H5H] A pipe-line, formed of pipe sections 57, 58, 59 and operating at an elevated temperature, is laid underground by heating each pipe section by the passing of an alternating current through an attached heat-generating pipe 60, 61 or 62 or pipes to elongate each section to a length between that of an unstressed section at environmental temperature and at operational. temperature, connecting each elongated section to a previously laid section, and backfilling earth on to each section to hold the resulting pipe-line. All but the ends of each section 57, 58, 59 is buried initially, the sections then being heated to expand against the frictional forces of the surrounding earth and then connected to form the pipe-line which is completely buried and held by the earth. Alternatively, each section 57, 58, 59 is initially heated and then backfill earth is placed around the pipe section at a temperature slightly lower than the sections' temperature. For these methods, the sections 57, 58, 59 may have an insulating cover. A further alternative is to place a small amount of backfill earth around each section, heat each section with the earth, and complete the backfilling with earth at environmental temperature. Each heat generating pipe 60, 61, 62 has an insulated wire passing through its bore connected at one end to a single phase A.C. generator and at the other end to one pipe end, the other pipe end being connected to the generator; a P.D. is set up along the inner surface of the pipe, which does not penetrate to the outer surface, and heats the pipe. Alternatively, two or three pipes may be connected to a single or threephase A.C. supply, the insulated wires forming a closed circuit, with the pipes connected to each other to form a separate circuit.

Abstract: 1,266,871. Mechanical figure. J. P. RUSSELL. 10 April, 1969 [28 June, 1968], No. 30899/69. Headings A6H and A6S. A model human figure which can be manipulated to perform certain functions of a game comprises a fixed part and a part connected to the fixed part for angular movement relative thereto a torsion spring acting between the parts to cause angular movement of said part in one direction and releasable adjustable ratchet means whereby the angular movement of the part in said one direction can be prevented. The figure illustrated is intended for use in playing golf and comprises a base 1 which is integrally formed with the lower torso and legs portion 2 which carries an upwardly inclined spindle 3 upon which is rotatably mounted an upper torso and arms portion 4. At the upper end of the spindle is a fixed head portion 5 which is non-rotatably secured to the upper end of the spindle by means of a screw 6. Acting between the portions 2 and 4 is a torsion blade spring 7 mounted in a recess in the lower part of the portion 4. The spring tends to rotate the part 4 relatively to the part 2 so that the arms execute a swinging movement corresponding to a right hand golfers movement. In the external surface of the lower end of the part 4 are a plurality of notches 8 with any one of which a catch 9 can engage. The catch is mounted on a pivot pin 10 and backed by a coiled compression spring 11 in the lower portion 2, which urges the catch 9 into engagement with the notches whereas pressure on the end of the catch 9 causes the catch to move against the spring 11 and disengage the catch from the notches. The arms of the figure are drilled to detachably receive a club 12. In use, the upper part 4 is rotated against the action of the spring 7 to a position where the catch 9 will engage a selected one of the notches 8. The catch is then pressed against the action of spring 11, permitting the upper torso, arm and club to move angularly and strike the ball. The figure may be modified for playing other games, e.g. football wherein the figure has one angularly movable leg controlled by a spring releasable ratchet mechanism.

Movement of the valve between its end positions is effected by pressures exerted on it through the inlets 15, 16. As described, lubricant and/or coolant is supplied via inlet 16 at a constant pressure and the pressure medium at a higher pressure is supplied intermittently via the inlet 15. Thus when there is no supply of pressure medium, lubricant and/or coolant is fed into the measuring chamber via channel 8. Supply of the pressure medium will move the valve to the position shown in which it abuts stem 5 of a screw 6, thus permitting supply of pressure medium to the measuring chamber via channel 9 and dispensing of the lubricant and/or coolant via channel 7, groove 3 on the valve and channels 10, 11. The volume of the chamber 13 can be varied by adjustment of screw 14. In an alternative apparatus (Fig. 3, not shown) the bottom wall of the measuring chamber is defined by a piston (17) adjustable by means of screw (18). The valve instead of having a groove may have a through bore, the valve in this case being prevented from rotating relative to the chamber 12. Each of the channels 7, 8 and 9, may be replaced by a respective plurality of parallel channels (e.g. two such channels).
