Title: Screening
IPC: B22D31/00
Filed: 1980-04-10
Abstract: A method of screening a mass of granular material comprises introducing the material at (11) into a rotary shakeout device (10) and initially screening the material in an initial screening section (20) to remove some of the grains from the mass, agitating the remainder in an agitating section (B) containing bars (35) to break up any remaining lumps in the material, and further screening the material in a further screening section (not shown) downstream of the agitating section. The method may be employed to remove sand from castings wherein at least some of the loose sand is removed in the initial screening section (20) so that the castings are not cushioned in the agitating section (B). <IMAGE>

Title: Storage system
IPC: B65D90/04
Filed: 1980-05-16
Abstract: The invention relates to a means of bulk storage of fluids in underground caverns that are normally water-filled. Lining water- filled caverns with a flexible impermeable membrane by conventional means is very difficult, normally requiring emptying of the cavern first or use of divers. The invention lines the cavern (1) with a flexible container (6) of density greater than water by placing it in the cavern, positioning a buoyancy means (7) in container (6) to raise the latter until a portion of it touches the roof (4) of the cavern and then pumping fluid of density less than water into the container. The container thereby gradually fills, expelling water from the cavern, and conforming to the roof (4) and then walls (3) of the cavern as it fills. The buoyancy means (7) is preferably a tube filled with nitrogen. <IMAGE>

Title: Method and Apparatus for Propelling Projectiles
IPC: E02D7/00
Filed: 1980-09-08
Abstract: Projectile-propelling apparatus, especially for operating under the sea to fire probes into the seabed, comprises a projectile carrying a main piston 2 and a lock piston 3. The lock piston is prevented from moving by a trapped volume of liquid 6 and piston 2 is exposed to the difference (P1-P2) between the ambient pressures at the firing location and at the sea surface. When space 6 is evacuated, piston 3 moves and separates from the projectile, allowing piston 2 to accelerate the projectile until it in turn disengages from it and projectile alone is fired from the apparatus. <IMAGE>

The undercut recesses can be formed by an inner circumferential groove in the outer member. One form of removing tool is also described. <IMAGE>
Patent GB-2089275-A (GB)
Title: Precision forming of thermoplastics articles
IPC: B29C48/07
Filed: 1980-10-24
Abstract: A blank strip of a thermoplastics material is formed into an article having a high quality surface finish by subjecting the strip (12) to a preliminary moulding step which imparts the surface finish to the blank which is essentially that required for the finished article and then subjecting the strip to a final moulding step which imparts the required moulded shape. The two steps may be performed in a single die block (17) having two distinct sections (21) and (22) for the two steps respectively. The strip (12) conveniently is urged through the die block (17) by hydrostatic pressure generated by pump (14) in a closed tube (10) leading to the die block (17), the pump delivering to the tube (10) a liquid which also serves as a lubricant. Following moulding, the strip is suitably supported by a guide (23) and then rolls (24), whereafter the strip is force-cooled by water sprays from nozzles (26). <IMAGE>

Patent GB-2066162-A (GB)
Title: Stamping out die
IPC: H05K3/04
Filed: 1980-12-19
Abstract: The invention provides a novel method for manufacturing a knife-edge die for stamping out a metal foil on an insulating base plate such as in the preparation of an electronic circuit board by a technique of photoetching. The method comprises providing a line pattern of a photoresist film on the die face corresponding to the contour of the desired pattern, subjecting the die face to a first etching to effect substantial side etching behind the photoresist film to leave an edge, removing the photoresist film and subjecting the die face to a second etching to sharpen the edge into a knife edge. The invention further proposes several improvements in the knife-edge die manufactured according to the principle of this method such as the adjustment of the depth of the inside recess surrounded by the knife edge with a filling material and knife-edge dies suitable for continuous stamping out provided with one or more flat-headed presser dies for the preliminary bonding of the metal foil to the base plate prior to stamping out with the knife edge and one or more limiter dies provided on one or both sides of the knife edge in order to prevent unduly deep incision of the knife edge to the base plate.

Title: Water tap
IPC: F16K31/524
Filed: 1981-03-13
Abstract: A tap has a valve member 26 biased open by a spring 36 and is actuated by a lever 38 having a cam 58. The cam 58 acts on a cam contact element 74 disposed on the valve body in a position away from a plane including a center axis of the main body. A pair of grooves are formed on the lever at each side of the cam and extend along the plane and a pair of projections 32, 34 are provided on the valve member 26 and inserted into the grooves. When the lever 38 is rotated in one or the other direction in the plane by an external force, the valve body is moved between the open and closed positions by the action of the cam. When the external force is removed, the lever is rotated in a direction traverse to the plane by the spring 36 out of line pressure acting through the cam contact element 72 and the projections are frictionally engaged with the lever to prevent the lever rotating in the plane and therefor the tap is held in the actuated position. <IMAGE>

Patent GB-2105456-A (GB)
Title: Cooling system
Inventor: HAMILTON IAN
IPC: F02B3/06
Filed: 1982-06-22
Abstract: A process fluid 15 (such as the charge air of a compression ignition engine) is passed successively through two heat exchangers 11 and 13 to be cooled by a motive fluid supplied from a pump 10. The heat energy imparted to the motive fluid in the heat exchanger 11 is utilised to power an ejector 16 which reduces the pressure of the motive fluid in the heat exchanger 13. The motive fluid thus has its boiling point lowered so that it is able to cool the charge air to a greater degree than would be possible if it were to be maintained at normal pressure, without the need to provide a separate power source to achieve the pressure reduction. From the ejector 16, the motive fluid passes through a cooler 17 (which may be a radiator of the engine) and is returned to the pump 10. In an alternative embodiment (Fig. 2, not shown), prior to being cooled by the cooler 17 the motive fluid passes through a further heat exchanger (19) where it cools the process fluid at a point intermediate the heat exchangers 11 and 13. <IMAGE>
