Title: Strainer/check valve for the structure pipe of a pump
IPC: B01D29/11
Filed: 1978-10-31
Abstract: The strainer includes a hollow body 1 and an inlet sieve 3. The inlet sieve is fixed by its upper part in a first plate 4 and by its lower part in a second plate 5 and the sieve is arranged to be slidable in the hollow body. A circular ring 7 serves as a stop for the first plate and forms a guideway for axial movement of the sieve. When the pump is not working, the sieve falls and the first plate 4 rests on ring 7 to seal the suction pipe inlet. Upon operation of the pump, sieve 3 is forced upwards, e.g. to an extent controlled by a guide ring 6 which may carry a sieve cleaning element 7, allowing flow into the suction pipe via the sieve. Vanes may be mounted within the sieve to give it rotational motion upon flow of liquid therethrough enabling cleaning of the sieve outer surface by fixed brushes. <IMAGE>

Title: Carbon fibre controls
IPC: H01M10/39
Filed: 1980-05-16
Abstract: In a sodium sulphur cell, having a cathode structure 15 (Figure 1) between a cathode current collector 14 and a solid electrolyte 10, the cathode structure is formed of a fibre material with at least 90% of mesophase-pitch-based carbon fibre material with the fibres oriented in two dimensions parallel to the plane of a mat, the mat then being needle-punched to re-align fibres and so increase the electrical conductivity transverse to the plane of the mat. Preferably up to 10% of a material having a greater resistance to bending is incorporated before needling; these may be carbon fibres which are non-mesophase-pitch-based. Alumina or other electrically non-conductive fibres may alternatively or additionally be incorporated. These further fibres can be chosen to improve the resilience of the cathode structure. The mat is impregnated with the cathodic reactant, i.e. sulphur or sodium polysulphides in liquid form and cooled while compressed to solidify the reactant and form a rigid unit for insertion in the cell, which unit will expand when the reactant is liquified at the operating temperature. <IMAGE>

Title: A method of photographic printing and a photographic original plate for use therein
IPC: G03F7/22
Filed: 1980-12-18
Abstract: By providing a photographic original plate (6) on which an original picture image (7) and a light-shielding mask (9) are formed, two identical pictures can be formed by exposing a sheet of photosensitive material with the original plate placed thereon and repeating the procedure after rotating the original plate through 180 degrees about the point of symmetry between the picture image and the light- shielding mask. Although the two printed images are inverted relative to each other, no problem arises when the final prints are eventually cut apart along a central line. Through adoption of the method and the use of the novel photographic original plate, not only the printing process becomes simpler than the conventional method but a better result in the final prints can be obtained. The marginal areas automatically receive an auxiliary exposure. <IMAGE>

Patent GB-2077336-A (GB)
Title: A sealing strip and a method of using the same
IPC: E06B5/16
Filed: 1981-05-19
Abstract: A method of and a strip for sealing a gap between a door leaf and frame of a fire-protection door. The strip 2 consists of a core 8 and a jacket 7 which seals the core 8. The core 8 is made of a material which effervesces under the action of heat and the jacket 7 of a material which is resistive to mechanical and chemical stresses and which is limitedly elastic but which is not heat-resistant. The choice of material for the core 8 and the jacket 7 is so made that the core 8 and the jacket 7 react differently to heat. Their reaction to heat is such that initially the jacket 7 softens and the core 8 releases gases which inflate the softened jacket 7. The core 8 expands in unimpeded manner into the thus-enlarged jacket hollow space, by effervescing and, in so doing, increasing in volume so that it fills the intermediate space of the gap and seals it. The jacket 7 then melts. <IMAGE>
