Title: Narrow gap arc welding apparatus
Inventor: SATO SHOZO
IPC: B23K9/02
Filed: 1982-04-02
Abstract: In a narrow gap arc welding process, a consumable electrode 16 fed into and along a narrow gap 2 between a pair of members 1 to be welded is deformed plastically to have a wave-like shape with a pitch of about 10 to 30 mm and a width of about 2 to 5 mm depending on welding conditions, and is fed into the gap with its wave extending across the width of the gap, so that the tip of the consumable electrode as it is fed and consumed points to the respective members to be welded alternately at a high frequency. The electrode is fed and deformed by passing between meshing gear wheels 17a, b with triangular teeth. <IMAGE>
Patent GB-2109119-A (GB)
Title: Tension indicating device
Inventor: JELFS STEWART DUDLEY
IPC: F16B31/02
Filed: 1982-06-04
Abstract: A cavity between two component loaded parts is filled by extrudable material, for example a soft rubber 'O' ring. One component 2 comprises a flat surface which closes an accurately-sized groove made in a mating surface of the other component 1 in order to form the cavity. A passage extends from the groove to an external surface of the other component. Load applied across the assembly produces mechanical strain which reduces the effective volume of the cavity. The extrudable material is therefore displaced through the passage until it produces a detectable protrusion from the external surface of the material or of a plunger which may be re-set. The device may be applied to many types of loaded members such as load-cells and linkages, but it is particularly suitable for fastening devices such as bolts where correct pretensioning is very important in minimising failure by fatigue. <IMAGE>

Title: Child-proof screw-threaded closure
Inventor: GOLDE ERICH
IPC: B65D41/04
Filed: 1982-07-08
Abstract: A screw-threaded closure for a container having a neck formed with an external screw thread having a plurality of peripherally spaced recesses 6, comprises an outer member 1 including a continuous dependent skirt and an inner member having a cover plate 2, one of the inner and outer members being formed with an internal screw thread 20 rendered discontinuous by grooves 5 and the other member being integrally formed with a plurality of bars 3 provided with threads 3a which bars 3 are received in the grooves 5 in the said one member. The other member is axially displaceable relative to the one member between two latching positions. In a first latching position the threads 3a on the bars are in alignment with the threads 20 on the said one member and in the second latching position the threads 3a, 20 are out of register by approximately half a thread turn. Each of the latching positions is defined by a projection on a first of the members engaging a recess on the second of those members. When the closure is fully screwed home, a cam 8 on the container engages the other member to move it to the second latching position. Unscrewing is achieved by initially rotating the cap slightly so that the other member can be pressed axially downwards into the first latching position. <IMAGE>

Title: Process for manufacturing metallic soap
Inventor: HAYASAKA ICHIRO
IPC: C07C51/41
Filed: 1982-08-06
Abstract: A process for manufacturing a metallic soap is provided in which a powdered aliphatic acid and at least one powdered metal oxide, metal hydroxide or a hydrate thereof are homogeneously mixed under agitation. The resultant mixture is agitated within a temperature range from a temperature 30 DEG C lower than the melting point of the aliphatic acid to a temperature just under the melting point to convert part of mechanical energy generated into thermal energy and to cause a reaction between the powders. The mixture is further agitated within a temperature range from the melting point of the aliphatic acid to a temperature just under the melting point of the metallic soap so as to remove under suction water produced by the reaction while maintaining the mixture in the form of the powder.

Inventor: COKER RAYMOND DOUGLAS
IPC: A23L11/30
Filed: 1982-10-28
Abstract: A process for decontaminating an agricultural product especially groundnut cake, contaminated with aflatoxin involves treating the contaminated product with water, preferably in the form of steam, until the product is moistened to a level of from 8 to 20%, preferably 12 to 18%, (by wt) of water, treating the moistened product with gaseous ammonia, until the level of ammonia in the mixture is from 1 to 10% (by wt) and the pressure in the reaction vessel is between atmospheric and 40 psi, and retaining the temperature of the mixture between 10 DEG  and 150 DEG C until at least 90% (by wt) of the aflatoxin is destroyed. Generally the reaction is performed in an insulated pressure resistant vessel and the heat for the reaction is generated, first, from the steam, and second, from the exothermic reaction between the ammonia and the moistened cake.

Title: Apparatus for inserting single sheets into a sheet stream fed to a copier from a cassette
Inventor: THOMSON MICHAEL BARRY
IPC: B65H5/26
Filed: 1984-07-02
Abstract: A single sheet inserter for a machine that uses sheets of paper contained in a cassette, such as a xerographic copying machine. Sheets are normally fed from the cassette one at a time by feed rollers (12) which engage the top sheet to the stack. The stack of sheets in the cassette is spring-urged into engagement with the feed rollers. When it is desired to insert a single sheet, it is placed on a partial cover of the cassette, and a gate mechanism (25) is activated to press the stack of sheets in the cassette out of contact with the feed rollers. The gate also acts as a registration gate for the sheet. By placing the leading edge of the single sheet in contact with the gate, its leading edge is located adjacent the feed rollers ready for feeding. in order to feed the single sheet, the gate is raised, allowing the stack of sheets in the cassette to push the single sheet into contact with the feed rollers, which are then rotated. <IMAGE>

Title: Clay dewatering process
Inventor: WILLIS WALTER R
IPC: B28C1/08
Filed: 1984-12-31
Abstract: A two-stage method for dewatering aqueous, low-solids kaolin clay slurries comprises carrying out initial dewatering of the slurry on a mechanical filter to produce a wet filter cake of no more than 57% by weight solids, which is a lower than usual solids content. Discharge of the wet filter cake from the filter cloth is facilitated by use of a suitable organic polymeric flocculating agent, preferably an aminoplast resin. The wet filter cake is then dispersed by addition of a suitable deflocculant and is filtered by an electrofilter to form a concentrated slurry of about 65 to 80% by weight solids. The electrofilter is preferably an electrically augmented vacuum filter having perm-selective membrane-equipped anodes to control or prevent anion and gaseous vacuum product contamination of the filter cake which provides the concentrated slurry. <IMAGE>
