Abstract: 1,055,958. Refrigerating. BALTIMORE AIRCOIL CO. Inc. Oct. 26, 1964 [April 27, 1964], No. 43603/64. Heading F4H. Water distributing means in an evaporatively cooled refrigerant condenser assembly comprise a plurality of parallel U-sectioned troughs 11, the walls thereof having V-notches, those of one wall being staggered with respect to those of the other, the troughs being fed from a common distribution box 21 (Figs. 1-4, not shown) through orifices in a wall thereof and at a level below that of a baffle plate 22 having orifices 24, in each trough. Water flows evenly over the V-notches and downwardly over both sides of the troughs.

Abstract: 1284726 Bituminous composition SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 11 Sept 1969 [13 Sept 1968] 43695/68 Headings C3N and C3P A bituminous composition comprises (a) 45-93% by weight of a wax-free bitumen, (b) 6-40% by weight of a filler comprising petroleum wax and (c) 1-15% by weight of a block copolymer having the general formula A-B-A in which each A represents identical or different thermoplastic, non-elastomeric blocks derived from a monovinyl aromatic hydrocarbon and in which B represents an elastomeric polymer block derived from a conjugated diene, said elastomeric polymer block B being optionally partially or fully hydrogenated. The use of the expression "wax-free bitumen" should not be taken as meaning the invention does not envisage the use of bitumens containing wax but only that if they do it is necessary for calculating the proportion of wax-free bitumen in the composition to deduct the quantity of wax present in the bitumen and include it with the filler. The monovinyl aromatic hydrocarbon may be styrene or α-methylstyrene, whilst the preferred dienes are butadiene or isoprene. Examples of suitable block copolymers are polystyrenepolyisoprene - polystyrene and polystyrenepolybutadiene-polystyrene. Suitable bitumens are distillation bitumens, precipitation bitumens, blown bitumens or blends thereof optionally with aromatic petroleum extracts, aromatic petroleum distillates or paraffinicnaphthenic petroleum distillates. Preferred fillers are those petroleum waxes melting between 60‹ and 140‹ C., which in the molten state are miscible with the bitumen-polymer blend. The bituminous composition may also contain conventional additives such as wetting agents, anti-oxidants, anti-foam agents and silicones. For applications in road building mixtures of 3-15% by weight of the bituminous composition and 85-97% by weight of graded material and cutbacks containing 70-90% by weight of the bituminous composition in question and 10-30% by weight of a volatile organic solvent containing more than 30% aromatics are not suitable. In such applications the bituminous component preferably has a penetration of 50-500 dmm. at 25‹ C. In industrial applications suitable mixtures comprise 40-70% by weight of the bituminous compositions in question and 30-60% by weight of a volatile organic solvent containing more than 30% aromatics and in such applications the bituminous composition preferably contains 5-15% by weight of the block copolymer and the penetration of the bituminous component is preferably 10-1000 dmm. at 25‹ C.

Abstract: 1,030,166. Multi-colour xerographic printing. RESEARCH LABORATORIES OF AUSTRALIA Ltd. Nov. 22, 1962 [Dec. 28, 1961], No. 44227/62. Heading G2H. In xerographic colour printing involving different colour images successively deposited on a photoconductive surface, the first image is developed with a developer comprising an electrically insulating carrier liquid having separately suspended therein a pigment of the appropriate colour and an electrically insulating bonding medium present in excess of the quantity required to coat the pigment so that such excess is co-deposited with the pigment to provide a coloured image deposit covered by a layer of bonding medium which is capable of accepting a uniform electrostatic charge and does not destroy the photoconductive properties of the surface. The surface is then exposed to the next colour image and the process is repeated. The bonding medium may be a natural or synthetic resin and the carrier liquid in each successive developer is preferably a poorer solvent for the deposited bonding medium than that in the preceding developer. There may be four colour images, e.g. blue, red, black and yellow. In the examples the bonding medium is a long oil alkyl resin and the carrier liquid is a 58 to 140‹C petroleum fraction containing 10% aromatics.

Title: Process for treating water
IPC: C02F1/72
Filed: 1960-12-28
Abstract: Water containing less than 5% by weight of oxidizable inorganic sulphur compounds, such as well water or waste water from a petroleum refinery, is treated with a free-oxygen containing gas (e.g. air or oxygen) in the presence of a phthalocyanine catalyst so as to oxidize the sulphur compounds and thereby render the water safe to aquatic life.  Inorganic sulphur compounds which may be present include (NH4)2S, Na2S, K2S, H2S, and the oxidation products include sulphates and thiosulphates.  The catalyst may be a metal (e.g. Co, V, Fe or Cu) phthalocyanine, or a metal phthalocyanine sulphonate or carboxylate, and may be used as a solid composite with a suitable carrier (examples given), or dissolved in water or aqueous NaOH, KOH, LiOH, or NH4OH solution.  Sufficient entrained air or oxygen may already be present in the water to eliminate the need for separate addition of free-oxygen containing gas.  The reaction temperature is usually ambient but may be up to 93 DEG C., or even higher if high pressure is used, the usual pressure for the reaction being 0,34 to 3,5 atmospheres.  The water may be passed through a fixed bed of a granular composite containing the catalyst deposited on a carrier, or may be treated with a slurry of a solid catalyst composite in water.ALSO:Water containing less than 5% by weight of oxidizable inorganic sulphur compounds, such as well water or waste water from a petroleum refinery, is treated with a free oxygen containing gas (e.g. air or oxygen) in the presence of a phthalocyanine catalyst so as to oxidize the sulphur compounds and thereby render the waste safe to aquatic life.

IPC: B29C45/67
Filed: 1962-11-28
Abstract: 1,031,099. Hydraulic presses; injection moulding machines. MANNESMANN-MEER A.G. Nov. 28, 1962, No. 45011/62. Headings B5A and B5F. Relates to hydraulic apparatus in which a member, e.g. the mould-carrying member 4 of an injection moulding machine is moved rapidly over the first and greater part of its advancing travel, locked against reverse movement and thereafter moved slowly over the last part of its travel, and is also moved slowly over the first part of its withdrawing travel and then rapidly for the remainder of its travel. According to the invention the member 4 is moved by apparatus comprising a movable cylinder 10 having two parts of different diameter, in the smaller of which is a fixed piston 8 and in the larger a movable piston 7, rapid movement being caused by movement of the cylinder 10 relatively to the fixed piston 8, and the slower movement by movement of the piston 7 relatively to the cylinder 10. For the first part of the advance movement, a lowpressure pump 13 supplies fluid through valves 15, 16, 17 and a bored piston-rod 18 to a chamber 20 within cylinder 10. Movement of piston 7 relative to cylinder 10 is prevented by springs 23 (Fig. 1, not shown), or a pressure accumulator 24 (Fig. 3b, not shown), or a high pressure pump 25 (Fig. 3c, not shown). When the cylinder 10 reaches the position seen in Fig. 2 (not shown), it is locked by means of plungers 11 and valve 15 is changed over so as to apply high pressure fluid from a pump 14 to the chamber 21. The pressure of springs 23 &c. is overcome, and a sealing element 22 lifted so as to expose the whole of piston 7 to the high pressure. By changing over valve 16 and then valve 15 low pressure high-speed opening is effected, the speed being further increased by changing over valve 17.
