Title: Improvements in or relating to the method of and apparatus for producing metal tubes
IPC: B21D26/02
Filed: 1955-02-28
Abstract: 766,515. Making tubes; stamping; altering physical structure. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Feb. 28, 1955 [March 3, 1954], No. 5819/55. Classes 83 (2) and 83 (4). A method of producing a thin-walled metal tube from a tubular member of greater wall thickness, comprises rigidly supporting said tubular member at each of its ends against lateral expansion and longitudinal movement, placing said tubular member within a chamber having the same interior contour as the desired exterior contour of the thin-walled tube and expanding the intermediate portion of said tubular member into engagement with said chamber by force uniformly applied to the interior of the tubular member. A stainless steel tubular blank of thickness approximately 0.018 inch is clamped at its ends between discs 4 and outer clamping rings 7, the discs being held in position by a tie-rod 8. One of the discs 4 is provided with an opening 11 through which pressure fluid is supplied to the interior of the blank from an hydraulic pump 13. The other disc 4 has an opening 20 communicating with a release valve 26. Sealing rings 25 in the discs ensure a fluid-tight joint. The assembly is arranged inside a cylinder 1 and the blank expanded to the contour of the cylinder. Where a large percentage reduction is required the deformation is accomplished in stages, e.g. of 20 per cent increase in outside diameter, using progressively sized cylinders, annealing being carried out between successive stages. After the forming operation the wall thickness has been reduced from 0.018 inch to approximately 0.012 inch and the outside diameter increased from 2.7 inches to approximately 4.6 inches. The stresses in the formed tube, which tend to contract the tube, are relieved by an air hammer 15 operating on the outer surface of the cylinder 1. In a modification an upright sizing cylinder 102 is provided with a flange 104 for bolting to a bed-plate 108. The tie-rod assembly comprising tie-rod 114 and discs 120 and 126 is placed into a tubular blank 124 and the assembly lowered into the cylinder 102. The blank is filled with fluid and the air release valve 138 closed. The hydraulic pump 146 is then operated to produce a pressure of between 1000 to 2000 pounds per square inch to expand the blank into engagement with the cylinder. As in the previous embodiment the cylinder is subjected to shock waves by an air hammer 150 having a brass or bronze head. Thin-walled tubes of various cross-sections, e.g. triangular, rectangular or polyhedral may be made by this method.

Title: Temperature control system
IPC: F24D5/00
Filed: 1950-03-08
Abstract: 667,884. Automatic temperature control systems. VAPOR HEATING CORPORATION. March 8, 1950 [March 25, 1949], No. 5867/50. Class 38 (iv). [Also in Group X] In an automatic temperature control system for a ventilation arrangement wherein a number of enclosed spaces are supplied with heat from a single source, the temperature in each space can be pre-set and is thereafter automatically maintained according to the heat demands of one of the spaces, called the control space, in which is positioned a thermostat controlling the output of the heater. In the form shown, air enters a duct 17 and passes through a steam or oil vapour heater 10 whence it is led by ducts 18, 19 and 20 into a control space 11 and two other spaces 12 and 13: Branch ducts 21, 22 and 23 carry cold air from the duct 17 to enter the discharge ends of ducts 18, 19 and 20, manually adjustable valves 27 and 28 being provided in spaces 12 and 13 to enable the mixture of hot and cold air to be controlled, thus allowing the space temperature to be adjusted. In the case of the control space 11, the hot to cold air ratio is fixed by a non-adjustable valve 24. The supply of steam or oil to the heater 10 is under the control of a thermostat 14 in space 11, the thermostat having a mercury column which shorts the operating coil of a relay 15 when the control setting is reached, the relay contacts then opening to break the current supply to a valve solenoid 16a, thus allowing a spring 31 to close the oil or steam valve to duct off the heater. The temperature of the air in ducts 18, 19 and 20, and consequently the temperature in spaces 11, 12 and 13 begins to fall until the thermostat operates to start the heater again. The control setting of the thermostat is adjusted by varying the flow of current to a small heater 26, which adds a measured amount of heat to the thermostat.

Title: Tertiary-aminoalkyl 4-amino-2-alkoxythiolbenzoate esters and their salts, and the preparation thereof
Filed: 1952-03-07
Abstract: The invention comprises tertiary-aminoalkyl 4-amino-2-alkoxythiolbenzoate esters of the general formula <FORM:0717777/IV (b)/1> (wherein X represents an alkylene radical of 2-4 carbon atoms in which the sulphur and nitrogen atoms are linked to two different carbon atoms, R and R1 represent alkyl radicals of 1-6 carbon atoms which may be joined directly or through an oxygen atom to form a saturated N-heteromonocyclic radical of 5-6 ring atoms, and R2 represents an alkyl radical of 1-6 carbon atoms), and their salts, and the manufacture of the free bases and their hydrohalides by reacting a 4-nitro-2-alkoxybenzoyl halide (e.g. chloride) with a tertiaryaminoalkanethiol HS-X-NRR1, reducing the nitro group to an amino group, and, if desired, neutralizing the resulting hydrohalide or effecting the initial condensation in the presence of a hydrogen halide acceptor (e.g. pyridine) to obtain the free ester.  The reaction may be carried out in the presence of an inert solvent, and the reduction may be effected by chemical methods (e.g. with iron or tin and hydrochloric acid, ferrous sulphate and ammonia or sodium hydrosulphite) or preferably by catalytic hydrogenation (using a sulphur-insensitive catalyst, e.g. molybdenum sulphide or cobalt sulphide).  The products are useful as local anaesthetics, either as free bases or in the form of salts with relatively non-toxic acids (e.g. hydrochlorides, hydrobromides, phosphates, sulphates, citrates, sulphamates, tartrates, succinates, acetates, benzoates or oleates).  Examples and tables describe products (and intermediate nitro-esters) containing various combinations of the following meanings for the symbols in the general formula: R2 = CH3, CH2CH3, CH2CH2CH3, CH2CH2CH2 CH3, CH2CH(CH3)2 and CH2CH2CH2CH2CH2 CH3; X = CH2CH2, CH2CH2CH2CH2CH2 and CH2CH2CH2CH2; NRR1 = diethylamino, piperidino and 2-methylpiperidino.

Title: Protective coatings on metals
IPC: C23C10/28
Filed: 1963-02-14
Abstract: A method of producing a corrosion and heat resistant coating on metals, particularly on austenitic high-temperature steels and on high temperature Ni or Co alloys, comprises applying a metallic intermediate layer containing Fe to the metal to be protected, then applying a protective layer of Cr to this intermediate layer and finally subjecting the whole to diffusion annealing in a non-oxidizing atmosphere or under high vacuum at a temperature between 1050 and 1250  DEG C.  The intermediate layer may consist of unalloyed Fe, an Fe alloy with 0.5-5% Al or an Fe-Ni alloy with at least 25% Ni. Both the intermediate layer, which may be 0.01-0.5 mm. thick and the Cr layer, which may be 0.01-0.5 mm. thick, can be produced by electrolysis, by flame-spraying or by dipping in a suspension of the appropriate metal powder. As an example, gas turbine blades of "Nimonic 80a" (Registered Trade Mark) are degreased, pickled, electrolytically plated with an Fe layer 0.04 mm. thick, from a bath containing ferrous sulphate, electrolytically plated with a layer of Cr 0.15 mm. thick from a bath containing chromic acid, annealed for 4 hours in an atmosphere of hydrogen at 1100  DEG C. and heat treated to achieve the necessary creep properties.

Title: Improvements in and relating to desiccation methods
IPC: H01G13/04
Filed: 1951-03-13
Abstract: 687,232. Drying electrical insulation. BRITISH THOMSON-HOUSTON CO., Ltd. March 13, 1951 [March 30, 1950], No. 6040/51. Class 34 (ii) Electrical insulation on a conductor or electrical apparatus 2 is dried by heating the insulation to a temperature between 105‹C. and 115‹C. in a container 1, circulating through the container a gaseous medium and abstracting moisture from this medium outside the container while the total pressure of the medium inside the container is maintained at atmospheric pressure or slightly above or below atmospheric pressure. The moisture is abstracted from the medium by a condenser 4 operated at a temperature between - 9‹C. and +45‹C. or by means of a desiccant such as silica gel or fuller's earth, circulation of the medium being carried out by means of a fan 7. Heating may be by means of steam pipes in the chamber or in the gas circuit or as shown in Fig. 3 a drying chamber 13 connected to a condenser and fan as in Fig. 1 has an open pool of a liquid 15 such as perchloro-ethylene having a boiling point of 120‹C. at atmospheric pressure and 110‹C. at 80 per cent of atmospheric pressure heated by steam pipes, the insulation being heated by the liquid in vapour phase which condenses on the insulation and gives up its latent heat. During this heating the chamber is isolated from the condenser circuit by closing valves 9, 10 and after heating the pool of liquid is removed, the pressure being raised by connecting the chamber to a nitrogen supply 16, to prevent ingress of moisture laden air. In a further modification the liquid is heated to a temperature below its boiling point and is vaporized by atomisation and in another modification air is blown through the pool of liquid. In yet a further modification heating is carried out by flooding the chamber with a heated liquid such as trichlorobenzene or by temporarily submerging the electrical apparatus in the heated liquid. The heating may be augmented, when the insulator is carried on a winding, by passing an electric current through the latter. Specification 535,194 is referred to.

Title: Improvements in and relating to the production of carboxylic acids
Inventor: SMITH JAMES CALDWELL
IPC: C07C51/02
Filed: 1960-02-22
Abstract: A free monocarboxylic acid or a fraction of two or more free monocarboxylic acids is obtained from a mixture containing alkali metal salts of the acid or acids and of one or more monocarboxylic acids having fewer carbon atoms, by treating an aqueous alkaline solution of the said salts with a mineral acid to lower the pH to a value at which the higher acid or acids are precipitated but at which the alkali metal salts of the acid or acids having fewer carbon atoms remain in solution, separating the higher acid(s) liberated as an acid phase and washing it to remove any occluded metal salts of the lower acid(s).  The process is applicable to aliphatic and aromatic acids and is particularly suitable for the separation of acids from a mixture of salts obtained by treating alcohols, produced by hydrogenation of oxo aldehydes, with caustic alkali.  For example C8 and C16 acids or C10 and C20 acids may be separated from mixtures containing their alkali metal salts.
