Class 44 In a stud and keyhole fastening device the stud is secured to a resilient strip provided with a latch, comprising a projection pressed out of the plane of the strip, the arrangement being such that when the stud is located in the narrow end of the keyhole, the latch engages a portion of the member, provided with the keyhole, to prevent movement of the stud longitudinally of the keyhole from the narrow end thereof. As shown, a shud 1 which comprises a tee-nut 4 having a flange 5 and dependent legs 6, is provided with a resilient clip 7 secured to the lower ends of the legs 6 and forms the base of the stud. The clip is formed by two bowed portions 8 and 9, the portion 9 being provided with a tongue 13 which when the stud is engaged in the narrow end 16 of the slot 3 in a member 2, abuts an end wall 20 at the other end of the slot to releasably retain the stud in position. In this position, the clip 7 completely covers the slot 3. A component may be secured between the member 2 and a screw 21 which co-operates with the nut 4, the tightening of the screw then flattening the clip between the component and the member 2. The stud may form part of a component and the screw and nut connection be dispensed with. The slot 3 may be a groove, wedge shaped in plan view, the stud being suitably shaped to co-operate therewith.

To produce a rotor for a variable capacitor, an unfired titanate ceramic disc 210 has half of its top surface 212 metallized with palladium paste. Thereafter the disc is stacked with a number of unfired discs 213, 214, 215 and the stack is compressed in a suitable die. The pressed stack is fired to fuse all the elements together. To make electrical contact with the electrode 212, silver paste is applied to the inside of an opening through the stack and to half of the top of the stack (in registry with the electrode). In a capacitor including such a rotor, the stator electrode is situated very close to the bottom surface, and the construction enables a very thin dielectric to be supported between the rotor and stator. Such a structure may be used in a trimmer capacitor as shown in Fig. 15 wherein the rotor unit 220 is attached to a screw 233 and held compressed against the stator carrying surface 240 by the spring arrangement 234.

Title: A method for the conversion of lead sulphate into lead dioxide
Inventor: JASZKA DANIEL JOHN
IPC: C01G21/08
Filed: 1956-11-19
Abstract: 819,275. Perchlorates and perchloric acid ; lead compounds. OLIN MATHIESON CHEMICAL CORPORATION. Nov. 19, 1956, No. 35369/56. Classes 1 (2) and 1 (3). Lead dioxide is prepared by reacting lead sulphate in aqueous medium with an alkali metal carbonate and passing in chlorine whilst maintaining the medium at a pH greater than 7. The initial reaction which is considered to result in the formation of lead carbonate, may take place in the presence of the stoichiometrical quantity of alkali metal (e.g. potassium or sodium) carbonate or an excess, at a temperature of 70-90‹ C. Additional carbonate may be added if necessary before chlorination to ensure that the reaction mixture remains alkaline during chlorination. The initial lead sulphate may have been formed and the final lead dioxide may be used, in a process wherein an alkali metal or alkaline earth metal chlorate is reacted with lead dioxide and sulphuric acid to form an alkali metal (e.g. potassium or sodium) or alkaline earth metal (e.g. calcium or magnesium) perchlorate. In this process, the sulphuric acid is preferably of 55-70 weight per cent strength in from 1.5-6 times the stoichiometric quantity at 90-120 C. In the case of potassium, if the reaction mixture is cooled the precipitate will contain both the lead sulphate and potassium perchlorate, from which the latter can be obtained by hot water leaching and cooling to crystallize. Alternatively the hot mixture may be filtered and potassium perchlorate recovered in crystalline form by cooling the filtrate. In the case of sodium, lead sulphate only is precipitated, and sodium perchlorate may be recovered by evaporation and cooling of the aqueous liquid. Alternatively perchloric acid may be directly recovered by simple distillation.

Abstract: 489,539. Refrigerating. JERRARD, E. P., and JERRARD, P. H. Dec. 28, 1936, No. 35475. [Class 29] Ventilating-air in mines and other places is cooled and dried by circulation over the tubes 1, Fig. 1, of an interchanger, in which compressed air expands in contact with a body of liquid, the liquid serving to displace the piston 4 of a motor performing external work, such as driving an electric generator 10. The compressed air is admitted by a valve 6, actuated from the motor crank-shaft 7, alternately to each of two similar sets of tubes 1 connected to opposite ends of the cylinder 3, and the admission is cut-off before the end of the piston stroke to allow the air to expand. The ventilating-air may be circulated by a fan 8 driven from the motor shaft. In another arrangement, the motor is connected in tandem with a cylinder for circulating the ventilating- air around the tubes, and a trap for separating moisture condensed out of the ventilating-air is provided. The exhaust expanded air may be mixed with the ventilating-air. In the arrangement shown in Fig. 3, compressed air is expanded in tubes 1 and forces a body of liquid before it through a pipe 3 to an elevated reservoir H, from which the liquid flows, under control of a valve 16, to a turbine 7 driving a generator 10 or a rock hoist. The liquid is discharged into a tank S and is readmitted to the pipe 3 through valves 20. In another arrangement, compressed air is admitted alternately to two sets of tubes connected by a pipe in which a body of liquid oscillates. The tubes may contain copper shavings to assist in the heat transfer, and the apparatus may include a regenerator chamber containing laminated plates for storing and giving up heat.

Title: Process for the preparation of a light hydrocarbon oil freed or substantially freed from mercaptans
IPC: C10G27/04
Filed: 1959-10-22
Abstract: Colourless or substantially colourless light hydrocarbon oils, e.g. kerosene, gasoline or jet fuel, having a phenol content not below 0.01% by weight and a boiling range of 150 DEG -275 DEG C., are freed from mercaptans by treating the oil in the presence of oxygen with an alkali metal hydroxide solution, suitably potassium hydroxide containing as solutizer (a) a formate and/or an acetate, generally the alkali metal salts, and suitably the potassium salts, and (b) a substance which promotes the solvent power for oxygen, for example a mono-, di- or trihydric alcohol such as diethylene glycol or glycerol, a partial ether of a polyhydric alcohol such as methyl or ethyl "Cellosolve" (Registered Trade Mark), or acids containing alcoholic hydroxyl groups such as tartaric, gluconic or hydroxybutyric acids; triethylene glycol is preferred.  The solutizer composition generally comprises 10-70%, preferably 40-65%, by weight of the alkali metal hydroxide solution; in general the weight ratio of (b) to (a) in the solutizer composition is 3:1 to 1:3.5, preferably 1:2 to 1:3 where (a) is a formate, and 3:1 to 1:3, preferably 1:2 to 1:2.5 where (a) is an acetate.  The alkali metal hydroxide present in the solution is usually present in an amount of 1-20%, preferably 14-17%, by weight, and the hydroxide solution containing the solutizer is generally mixed with the oil in a volume ratio of 0.05:5, preferably 0.1 to 1.  The process is normally carried out at 0-70 DEG C., preferably 15-55 DEG C., at atmospheric pressure, and the oxygen may be used as such or in admixture with inert gas, e.g. as air, generally in an excess of 50-200% over the quantity of mercaptan to be oxidized. Alternatively, a peroxide may be used in amounts of 10-40% of the stoichiometric equivalent of the mercaptans to be oxidized, in which case the oxygen need not be present in excess.  The process may be conducted continuously or batchwise, by passing the oil and aqueous solution through a centrifugal mixer or by finely spraying either phase into the other to obtain a fine dispersion, air or oxygen being passed into the oil before or during admixture.  If any acids, e.g. hydrogen sulphide, are originally present in the oil, these may be removed by pretreatment, for example with sodium hydroxide.  When the process is used with oils obtained by cracking, gums may be prevented from forming by the addition of small amounts of antioxidant to the oil. Specifications 712,056, 759,560, 775,015 are referred to.
