Title: Improvements in or relating to apparatus having a stationary and a movable press platen, particularly an injection molding machine
IPC: B29C45/67
Filed: 1968-01-17
Abstract: 1,205,496. Injection moulding machines; presses. BRODERNA AKESSONS MASKINFABRIK A.B. 17 Jan., 1968 [19 Jan., 1967,[ No. 2585/68. Headings B5A and B5F. An injection moulding machine comprises a frame 10 having a stationary platen 12, a movable platen 13, and a member 11 which supports a number of hydraulic cylinders, not shown, from which extend piston rods connected to the platen 13 for moving it on wheels 13a. A tube 15 connected to the movable platen passes through the member 11 and can be interlocked therewith by an internally grooved bayonet type ring 16 on the member which is rotated to engage circumferentially grooved portions 17 on the tube. In operation, the platen 13 is advanced by the hydraulic cylinders until the platens are at a predetermined distance apart, which can be determined by a stop ring 21 on the rod 15 engaging the rear of the member 11. The tube 15 and ring 16 are then interlocked by turning the ring by an hydraulic cylinder, not shown, after which pressure is applied to the member 11 and hence to the platen 13. This latter pressure is produced by hydraulic cylinders 18 on the member and pistons 19, with piston rods 20 connected to the platen 12.

Title: Improvements in or relating to abrasive paper or like abrasive sheet and the method of making the same
IPC: B24D11/00
Filed: 1947-01-31
Abstract: Flexible abrasive paper is made by depositing a uniform suspension of short fibres of a wet feltable length and abrasive grains on a foraminous support, extracting liquid from the web then compacting and drying it.  Fibres such as unbleached sulphite paper pulp, cotton, bombax wool, linen, jute, manila, straw, esparto, palm, cocoanut, cellulose acetate and synthetic resin fibres and abrasives such as silicon carbide, fused aluminium oxide, emery, flint and rouge are suitable.  The paper which may contain over 40 per cent of abrasive grains may be made from a 0.5-5.0 per cent suspension of cellulose fibres which is agitated to gelatinize the fibres and so ensure intimate incorporation of the abrasive grains.  Binders such as latex, glue, vinyl- and urea-aldehyde synthetic resins may be added to the suspension or applied to the web.  Abrasive grains coated with the binder may be used.  The dried and compacted web may be heated to set the binder.  The suspension may contain a solvent or softener for the binder and a softener for the fibres, e.g. alcohol for cellulose acetate fibres.  The Specification as open to inspection under Sect. 91 also comprises a method of making the web by spraying the suspension on a foraminous support.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1,036,164. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. Jan. 29, 1964, No. 3785/64. Addition to 1,023,531. Heading H1K. A semi-conductor device formed by the planar diffusion technique has a composite nickel-gold contact to one of its regions and a conductive track extending over an oxide layer on the semiconductor body from the contact, the track grading from metal adherent to the oxide or its lower face to a soft-solderable metal on the exposed face. A typical transistor is made in multiple from an N-type silicon slice by oxidizing one surface and forming the oxide layer into masks for successive inpurity diffusions to produce the base and emitter zones, and for deposition of gold over exposed areas of these zones and of the undiffused area constituting the collector zone. The masks are formed by etching holes in the oxide using photo-resist techniques. The gold is overcoated with nickel, then alloyed to the wafer before receiving a thicker layer of nickel. A layer graded from chromium adjacent the oxide to gold above or from manganese to silver is then deposited over the entire surface and reduced by a photoresist etching technique to the form of three electrode films 20, 21, 22 per triangular transistor section (Fig. 1), in contact with the collector, base and emitter zones respectively. Alternatively, the films are deposited through a suitable mask. The triangles have their sides lying along lines of easy cleavage and are thus easily broken from the slice for individual mounting, e.g. with the electrode films soldered to metallized areas forming part of a thin film circuit on an insulating substrate as described in Specification 1,022,366. The invention is as applicable to diodes and solid circuits as to transistors and may also be applied to germanium devices using deposited silicon oxides as the masking and film bearing layer.
