Patent GB-2089694-A (GB)
Title: Tool holders comprising collet cartridges
IPC: B23B31/20
Filed: 1981-12-07
Abstract: In a collet cartridge, a split collet 1 extends through a housing 20 bolted to a tubular rotary shaft 9 in a power driven tool holder. Compressed disc springs 4, interposed between housing 20 and nut 3, screwed onto the rear of the collet maintain the collet in the closed condition by forcing tapered collet segments 22 into conical surface 23. To allow the collet to open for inserting a tool, plug 6 in a forward position on thrust rod 5 forces the collet forwards, increasing the stress in discs 4 and locking the screw connection between nut and collet. To avoid such locking, enabling a tool applied to projection 30 to unscrew the collet, a rim 28 on rod 5 forces nut 3 forwards to free the collet segments, after plug 6 has been screwed back by a tool inserted through the collet. Radial holes 30 are bored between collet segments 22 and rubber plugs 31 inserted to prevent passage of dust between segments. <IMAGE>

Title: Regenerating spent adsorbents
Inventor: CHANDRASEKARAN KRISHNAMOORTHI
IPC: B01J20/34
Filed: 1982-08-24
Abstract: Spent adsorption agents used for example in columns to refine glyceride oils and fats, are successively contacted with (1) an organic polar compound e.g. an alcohol such as isopropanol or a ketone to displace adsorbed impurities and (2) a superheated vapour of a hydrocarbon such as hexane, to reactivate the adsorbent by removing the adsorbed polar compound. The polar compound may be used in admixture with a hydrocarbon forming an immiscible azeotrope to facilitate solvent recovery. Silica and/or alumina or other adsorption agents may be repeatedly regenerated in accordance with the invention to refine fats such as palm, shea, sal and cottonseed oil.
Patent GB-2128595-A (GB)
Title: Pressure cap
Inventor: LARDNER GRAHAM GERALD
IPC: F01P11/02
Filed: 1982-10-06
Abstract: A pressure cap for a vehicle cooling system consists of two plastic sleeves, the outer one 1 of which has threads (3, 4; Fig. 1) engaging a filler neck and the inner one 2 of which has a seal (6, Fig. 1) for sealing against the filler neck. The inner sleeve contains the pressure relief valves. The inner and outer sleeves are secured together by a simple mechanical means consisting of four lugs 12 provided at the top of the inner sleeve, each lug being provided with a resilient tag 14. During assembly, the inner sleeve is inserted in the outer sleeve with lugs in alignment with lobes 4 in the outer sleeve. The inner sleeve is then rotated, and this resiliently deflects the tags 14 inwards. By the time that the inner sleeve has been rotated fully in a clockwise direction the tags are each level with a lobe and can spring outwards and prevent reverse rotation of the inner sleeve. The parts are then locked together since an inclined circumferential cam surface and cam follower (not shown) prevents any further rotation of the inner sleeve in a clockwise direction relative to the outer sleeve. <IMAGE>

Title: Procedure for the manufacture of a multi-layer circuit
Inventor: GERNOTH HARTWIG
IPC: H05K1/02
Filed: 1984-04-18
Abstract: In this procedure for the manufacture of a multilayer circuit employing thin-film-technology, a separating layer (3) is vapor-deposited onto the conductor tracks (2) belonging to the first circuit level, at the points where the conductor tracks are intended to cross one another. Thereafter, the substrate areas which are not covered by conductor tracks (2) are coated by the vapor-deposition of a first filler-layer (5). In the next step, the area which is not covered by the separating layer (3) is coated with a second filler-layer (7), likewise by means of a vapor-deposition process. The application of the filler-layers (5, 7) results in a plane surface at each circuit level. Following the application of the filter-layers (5, 7), the conductor track belonging to the second level can be applied. The second level is completed in the same manner, as are further levels of the multi-layer circuit. Oxides or glasses, exhibiting high melting points, are employed as the materials for the separating layers (3) and the filler-layers (5, 7), it being possible for the separating layers and the filler-layers to be composed of the same material. The vapor-deposition operations are, in all cases, effected with the aid of suitable masks. <IMAGE>

Title: Wire bonders
Inventor: OKIKAWA SUSUMU
IPC: H01L21/60
Filed: 1984-05-10
Abstract: A wire bonder useful for assembling electronic components with fine metallic wire. The wire bonder in accordance with this invention forms a ball at a free end of a bonding wire by utilizing discharge arc and thereafter bonds the ball to a component. The wire bonder of the invention has a construction in which the atmosphere between the tip of the bonding wire and a discharge electrode disposed adjacent the tip of the bonding wire can be maintained as a reducing gas atmosphere. Especially when an aluminum wire, which is an easily oxidizable thin metallic wire, is used as the bonding wire, the wire bonder of the present invention improves the sphericity of the ball formed by discharge arc as well as the bondability.

Title: Stable detergent emulsions
Inventor: BORSETH DONALD G
IPC: C11D1/72
Filed: 1985-02-15
Abstract: Either a built or non-built stable detergent emulsion composition is prepared from a nonionic surfactant or a mixture of nonionic surfactants which are either alcohol or alkyl aryl ethoxylates, as well as mixtures thereof, the surfactant having an HLB value below 13.0. The upper HLB limit corresponds to a cloud point ranging from 120 DEG F to 135 DEG F. By employing nonionic surfactants whose HLB and cloud point are no greater than the upper limit, high levels of nonionic surfactant, i.e. greater than 15 weight percent, can be incorporated into the emulsion. At lower HLB values, builders are not required. At higher HLB values, builders are necessary to form stable emulsions. The composition may be used for laundering or cleaning hard surfaces.
