Filed: 1926-06-28
Abstract: 259,920. Electro Metallurgical Co., (Assignees of Becket, F. M.). Oct. 15, 1925, [Convention date]. Cupped articles; tubes. - Seamless tubes or hollow articles are manufactured from iron-chromium alloys of approximately ten to twenty-five per cent chromium content by hot-piercing at a temperature lying approximately between 1000 C. and 1175 C., followed bv rolling, drawing or pressing. In preheating the billets the rate of nse of temperature should preferably be slow up to about 600 C. to avoid any tendency to crack. As an example, a batch of billets are slowly heated to 600 C. over a period of about one and a half to three hours, then to the piercing temperature in about 3 hours, and maintained at this temperature for an hour or more to secure an even temperature throughout the batch. The carbon content should be as low as possible, the following being the percentage composition of a material found commercially practicable to pierce and roll into satisfactory tubing: chromium 26.89, carbon 0.25, silicon 0.44, manganese 0.53, phosphorus 0.018, sulphur 0.02 nickel 0.542. Another suitable composition of material is chromium 24.37, carbon 0.18, silicon 0.37, manganese 0.96.

Title: Improvements in or relating to the preparation of alcohols by hydrogenation of aldehydes obtained by the oxo process
IPC: C07C29/16
Filed: 1952-07-01
Abstract: Alcohols are obtained by hydrogenating, at pressures not exceeding about 50 atmospheres, aldehydic material obtained by the Oxo process from alkenes containing substantially no 2-alkyl 1-alkenes or unsaturated hydrocarbons which, when subjected to such conditions as prevail in the Oxo reaction, polymerize more easily than 2-alkyl-1-alkenes, said alkenes being obtained by cracking hydrocarbons and subsequently refining them by treatment with strong sulphuric acid.  The 2-alkyl-1-alkenes are those having the formula R.R1.C = CH2 in which R and R1 represent alkyl groups.  The refining of alkenes obtained from paraffin wax by thermal cracking in the vapour phase may be effected by stirring the alkenic fraction with 4 per cent by weight of 98 per cent sulphuric acid at room temperature for 10 to 15 minutes, separating the acid-containing lower layer, washing with alkali solution and then distilling to remove sodium alkyl sulphates.  It is preferred to start with alkene fractions of narrow boiling range in which the difference in the number of carbon atoms between the lowest and highest molecular weight alkenes in the fraction is not greater than five.  In examples, (1) C8-C12, C13-C15 and C16-C18 alkene fractions obtained by vapour phase cracking of Venezuelan paraffin wax and which have been refined by treatment with strong sulphuric acid and finally distilled are reacted with water gas in the presence of a catalyst consisting of cobalt on kieselguhr at a pressure up to 140 atmospheres, each reaction being carried out in an autoclave maintained at 90 DEG  C. for half an hour, and the reaction being completed by further reaction at 140 DEG  C. and 200 atmospheres for 2.5 hours.  After removing cobalt and dissolved carbon monoxide by first cooling the material to 50 DEG  C. and reducing the pressure to 1 atmosphere, the contents of the autoclave are flushed with hydrogen, the hydrogen pressure increased to 25-30 atmospheres and the mixture maintained at 185 DEG  C. for two hours after which it is cooled to 50 DEG  C. and the pressure reduced to 1 atmosphere.  Hydrogenation is then effected under a pressure of 25-50 atmospheres hydrogen at about 185 DEG  C. for 2 hours in the presence of the cobalt obtained in the decobaltizing stage; (2) the refined C8-C12 fraction used in (1) is reacted with water gas in the presence of the same catalyst as in (1) in an autoclave kept at 90 DEG  C. for half an hour, the Oxo reaction being completed in about 6 hours at 140 DEG  C. and at 90-100 atmospheres pressure.  After decobaltizing as in (1) the hydrogenation is carried out at 185 DEG  C. under a pressure of 25-50 atmospheres for 3 hours in the presence of the cobalt obtained in the decobaltizing stage, the aldehyde content of the final product being 0.1 per cent.  Specification 698,554 is referred to.

Abstract: 1420076 Yarns IMPERIAL CHEMICAL INDUSTRIES Ltd 2 April 1973 [12 April 1972] 16830/72 Headings D1F and D1W In a composite yarn such as described in Patent Specification 1258905 and comprising a core component of set false-twisted synthetic continuous filaments and at least one wrapping component of synthetic continuous filaments which are formed in helices the directions of which reverse at intervals along the yarn, the core yarn has a decitex (the weight in grams of 10,000 metres measured under sufficient tension such that the core component is straight but not extended) of 120-400 and the core component has a decitex between 25 and 4% of that of the yarn. Yarn is "high order" or "low order" according to whether the filaments of the wrapping component are continuously or intermittently applied, these filaments having individual decitex of 2.5-7.5. Filaments e.g. of nylon or polyethylene terephthalate, for core and/or wrapping components may be physically and/or aesthetically different or similar e.g. as regards birefringence, natural draw ratio, cross-sectional shape (circular or trilobal) colour and/or dyeing affinity and/or may be bifilor or conjugate. In the manufacture of the yarn, using apparatus such as described in Patent Specification 1258905 and wherein the two components are supplied to, in sequence, a feed means, a heating zone, a cooling zone and a (frictional) false-twisting element, they are withdrawn therefrom under a higher tension than that under which they are supplied such that the filaments are drawn 1.5 to 6 times their feed length, the filamentary components differing as to their extensibility under the stresses on entering the yarn section of increasing twist gradient. The ratio of the decitex of the component of greater extensibility to the decitex of the component of lesser extensibility is within the range 1.5:1 to 3:1. The components may be subsequently modified by heat treatment under a controlled tension and temperature conditions.

Title: Improvements in or relating to pumps and pumping systems
IPC: F04D13/16
Filed: 1953-06-18
Abstract: 737,141. Centrifugal pumps. JACUZZI BROS., Inc. June 18, 1953 [Feb. 9, 1952], No. 16849/53. Class 110 (1). A multi-stage pump comprises two groups of impellers, one of which receives water from an injector within a deep well and delivers it to a tank, while the other draws water from the tank and feeds it to the injector. The tank supplies a water main. The injector 16, Fig. 2, is housed in an intake member having a strainer 102. Two impellers 28, 30 in series draw water from the tank 20 through passages 62 and 64 and deliver it through passage 66, outlet 68, Figs. 2 and 4, valve 88 and chamber 80 to a pipe 14 leading to the injector 16. The injector delivers water by way of a pipe 18, chamber 78, valve 82 and passage 54 to two further seriesconnected impellers 24, 26 which deliver it to the tank 20 by way of a passage 58 and pipe 61b. The pipe 61b extends a sufficient distance into the tank 20 to ensure that air entrained in the water discharged by the pipe is not drawn into the passage 62. When the pressure within the tank 20 has increased sufficiently, a pressureactuated switch stops the driving motor (not shown) of the pump. The resultant drop in pressure at the underside of a diaphragm 96 allows the valve 88 to drop to the closed position. Valve 82 closes when the flow from the pipe 18 ceases. With both valves closed, the water in the system above the valves is prevented from draining into the well. The space above the diaphragm 96 is connected by way of a duct 98 with the chamber 78, but may instead be connected to the tank 20 or to any point in the low pressure stages of the pump. The valves may be replaced by a foot valve in the well. To ensure priming, the connection of the water main to the tank 20 is located above the level of the impellers 28, 30.
