Abstract: 543,195. Moulding sliding clasp fasteners. LIGHTNING FASTENERS, Ltd. (Lightning Fastener Co., Ltd.). Aug. 12, 1940, No. 12870. Addition to 517,876. [Class 87 (ii)] Complementary moulds 9 slide vertically in slots 3 on the periphery of a drum 2, the moulds being controlled by cams 16, 17, with or without springs. A beaded edge 13 of a tape 14 is introduced between guides 33, 34 into the moulds.at A, and as the drum revolves the moulds close on the tape and non-metallic fluid material is injected into the mould space through a stationary nozzle 50 ; at B the moulds separate, and the tape with its fastener elements cast thereon is led off. The moulds 9, instead of sliding freely in grooves, may be hingedly joined at their inner extremities. Bore members 38, mounted stationarily on the drum, co-operate with the moulds 9 to form interlocking recesses in the cast members. Surfaces 70 and 74a on rings 72 and 74 respectively, together with a curved extension on the nozzle 50, close the side openings of the moulding cavities. Some of the moulds 9 may be dummies, having no mould cavities but merely grooves 12 for'the bead 13 of the tape ; the finished tape then has blank areas and may be cut into uniform lengths without the necessity of stripping off fastener elements. The moulding material is fed from the base of a hopper 47 by a spring(88)-and-cam(51)- operated piston 45 through a torpedo 49 to the nozzle. Heating elements 48, 66 and 67 are provided. A compensating plunger 62 tends to maintain a uniform pressure of injection. If the feed of moulding material is excessive, material escapes through a blow-hole 65. The hopper, together with the plunger 62, piston 45, cam 51 and nozzle 50, is carried by a frame 82 slidably mounted on bars 83 on a carriage 42 adjustable in slots 81 in the machine base. The frame 82 is urged to the left by springs 89. The shaft 52 of the cam 51 is driven from the shaft 27 which drives the drum. The moulding material may be fed by the screw described in the parent Specification.

Title: Improvements in and relating to methods for the removal of relatively volatile metals from their alloys with aluminium
IPC: C22B5/16
Filed: 1939-04-29
Abstract: 528,204. Distilling metals; alloys. LUMSDEN, J., and CALLOY, Ltd. April 29, 1939, No. 12892. [Class 82 (i)] Volatilizible metals such as zinc, cadmium, and magnesium are removed from aluminium alloys by heating the alloy in the presence of a gas which is inert to all the constituents of the alloy. For example, hydrogen may be bubbled through the molten alloy; or an alloy of 80 per cent. of zinc and 20 per cent. of aluminium may first be distilled, without using hydrogen, at 1200‹C. until the remaining alloy contains 17 per cent. of zinc, after which hydrogen may be bubbled through the molten alloy still at 1200‹C. whereby the zinc content is reduced to 0.05 per cent. In a similar manner an alloy of 80 per cent. of aluminium and 20 per cent. of copper may be obtained from an alloy of 95 per cent. of zinc, 4 per cent. of aluminium, and 1 per cent. of copper.

Abstract: 536,938. Anodizing aluminium and alloys thereof. McGLASSON, R., and BIRD, W. A. Aug. 17, 1940, No. 13140. [Class 41] Aluminium or aluminium alloys before being anodized by the chromic or sulphuric and oxalic acid methods are after polishing and cleaning with benzol, petrol, paraffin or alcohol, etched by treatment with nitric or hydrofluoric acid, ferric chloride, caustic soda or potash or alkaline earth hydroxides. Treatment with ferric chloride may precede or follow treatment with nitric or hydrofluoric acid. The anodized surface may be dyed by immersion in dye solution for example nigrosine in acetic acid and designs may be obtained by masking parts of the surface with gums, resins or shellac dissolved in alcohol, amyl acetate &c.

Title: Improvements in or relating to pulp refiners
IPC: D21B1/12

Abstract: 938,569. Pulp dewatering and refining devices. DEFIBRATOR A.B. April 13, 1960 [April 16, 1959], No. 13169/60. Class 96. In a combined pulp-dewatering and refining device, pulp suspension from a bin 38 is pumped by a pump 40 under superatmospheric pressure through a conduit 42, controlled by a valve 44, into the inlet of a dewaterer 26 comprising a tube 28, having perforations 30 and surrounded by a casing 46, and housing a rotatable scraper device, e.g. a conveyer screw, 32, driven by a gear 36. Water expressed from the pulp passes through the perforations 30 and leaves the casing 46 via a valve 50 and a drain duct 48, whilst the pulp, e.g. increased in concentration from 5-6% to 10%, passes to a device 66 which creates a counterpressure in the dewaterer 26 by means of a conical valve body 68 acting against the pulp flow with a pressure determined by a servomotor 70 housing a piston 72 which is supplied at one or other side with liquid or gaseous fluid. The pulp then enters, via a duet 20, between stationary and rotating grinding discs 16, 12 and is withdrawn through a duet 22, controlled by a valve 24, to a flute 52 provided with sills 54, 56 and thence to a collecting bin 58, a pulp concentration testing device 65 located between the sills controlling the valve 50 whereby a variable further counterpressure is produced within the casing 46 which regulates the intensity of the dewatering operation and therefore controls the concentration of the pulp suspension entering the refiner with respect to that withdrawn from it.

Patent GB-185374-A (GB)
Title: Process of producing crystalline titanium oxide
IPC: C01G23/047
Filed: 1921-06-27
Abstract: Crystalline titanium oxide free from iron is prepared from the iron-free titanium chloride obtained by the process described in Specification 184,948.  The chloride is dissolved in water and the solution neutralized to precipitate the hydrated or gelatinous oxide. This is dissolved in sulphuric acid, preferably of 25 per cent strength, and the solution boiled to reprecipitate the oxide. This precipitation is facilitated by slight hydrogenation, which may be effected either by direct addition of the gas, or by addition of zinc to the solution.  The amorphous oxide precipitated is calcined to yield the crystalline oxide.
