Abstract: 909,309. Pressure transducers. BORGWARNER CORPORATION. May 26, 1959 [June 4, 1958], No. 17928/59. Class 40 (1). [Also in Group XXXV] In a pressure transducer, the tension in a wire 120 is varied by the deflection of a diaphragm 110 to which the wire is attached by a collet 116. The wire vibrates between the poles of a magnet 138 at a frequency determined by an input current through a connection 136 from a bridge (see Group XXXV) which is balanced when the frequency to which the vibrating wire is tuned, by deflection of the diaphragm, is equal to the input frequency of the bridge.

Title: Process for the hydrolysis of aluminium alkoxides
IPC: C01F7/36
Filed: 1964-05-01
Abstract: Alcohols are obtained by the hydrolysis of a mixture of aluminium alkoxides which has been obtained by reacting an olefine with an aluminium alkyl to form a mixture of aluminium trialkyls and oxidizing this mixture, for example with air, the hydrolysis being carried out in a homogeneous liquid phase consisting of a solution of water in n-butanol.  The hydrolysis is preferably carried out at a temperature in the range 65-93 DEG  C. with the liquid phase containing 5-28% by weight of water.  The fatty alcohols formed dissolve in the butanol and are removed from the reaction zone.  A secondary product is flocculent aluminium hydroxide.  In the examples a mixture of aluminium alkoxides, obtained by the oxidation of a mixture of aluminium trialkyls which in turn had been obtained by reacting ethylene with aluminium triethyl, is hydrolysed in a medium of butanol and water.

Title: A process for improving the properties of polymers
IPC: C08J3/12
Filed: 1948-07-09
Abstract: Powdered polymers, e.g. polyvinyl chloride, the particles of which have "sintered," i.e. partially softened, surfaces, are made by dispersing in a gaseous medium a surface-dried powder obtained from a coagulated emulsion polymer and heating the dispersion, e.g. by mixing it with a flow of hot gas, vapour or mist.  The emulsion polymer may have been coagulated by the addition of organic liquids, freezing or by violent agitation of the suspension, then washed, dried and powdered by dropping the moist polymer upon a solid surface, e.g. the inside of a rotating drum, in an atmosphere of low relative humidity so as to disintegrate lumps.  In an example a polyvinyl chloride coagulum was made by emulsifying vinyl chloride in water with sodium cetyl sulphate, polymerizing at 45 DEG  C. in the presence of potassium persulphate, coagulating the latex by adding amyl alcohol, separating the coagulum by centrifuging and washing the coagulum with a sodium bicarbonate solution.  The powdered polymers may be compounded with plasticizers.  Specifications 589,715, and 661,886 are referred to.

Abstract: 461,229. Ironing machines. GEE, H. T. P. (Beatty Bros., Ltd.) July 3, 1936, No. 18574. [Class 138 (ii)] The movement of the bed 15 into and out of operative engagement with the roller 10 and the starting and stopping of the roller are controlled from a common shaft 34 having an operating handle 35. The shaft is provided with two cams 33, 36, of which the cam 33 acts on a yoke 32, Fig. 4, engaging an annular groove in a half-clutch member 25. The latter is slidably and non-rotatably mounted on the roller shaft 11 on which a constantly running worm wheel 23 having axial clutch teeth 24 is mounted. The clutch 25 is moved by a spring 27 into engagement with the worm wheel but is maintained out of engagement therewith by the cam 33 when the latter is in the full line position. The cam 36, Fig. 2, acts on a roller 20 on an arm 19 secured to the shaft 17 about which the arm 18 carrying the bed 15 is pivoted. To render the cam 33 non-effective whilst the cam 36 remains effective, whereby the roller may remain stationary with the bed in contact therewith so that the machine may function as a press, a manually rotatable cam 38, Fig. 4, is provided to act on an arm 40 secured to the yoke 32 whereby the latter may be retained in its elevated position and hold the clutch member 25 against the spring 27 and out of engagement with the worm wheel.

Title: Improvements relating to photographic emulsions
Inventor: HARRY DEREK EDWARDS FRANK PETE
IPC: G03C1/09
Filed: 1950-07-26
Abstract: 687,672. Photographic emulsions. ELLIOTT & SONS, Ltd. July 19, 1951 [July 26, 1950], No. 18636/50. Addition to 608,667. Class 98 (ii). The sensitivity to light of a gelatino silver halide photographic emulsion is increased by the incorporation of a small quantity of a waterinsoluble gold compound directly into the emulsion. The water-insoluble gold compound may be prepared by adding ammonia or a water-soluble silver salt to a water-soluble gold salt such as a complex halide or cyanide or a thiocyanate and filtering off and washing the precipitate. The precipitate may be dried before incorporation into the emulsion. The emulsion may be a silver bromide emulsion, which may contain a small proportion of silver chloride or iodide or both, may contain a hardener, preservative, and a stabilizer, and may be sensitized with an optical sensitizer. The addition of the water-insoluble gold compound is preferably made after the emulsion has been washed, but before or during final digestion. The pH of the emulsion should preferably be adjusted to about 5, e.g. with hydrochloric acid. In example 1, the pH of an undigested gelatino silver bromiodide emulsion is adjusted with HC1 to 5.2, and various quantities of a washed precipitate obtained by adding weak aqueous ammonia to an aqueous solution of potassium auribromide are added. Speed, gamma, and fog values are given for the emulsion without addition at digestion times of 30 and 90 minutes and also, at a digestion time of 30 minutes, for the emulsion with the optimum addition of gold compound. Similar data are given in example 2 for an emulsion to which a gold hydroxide/silver bromide complex, obtained by adding silver nitrate to potassium auribromide solution, has been added. Specification 682,355 is referred to. According to the Provisional Specification, the precipitation may be effected with pyridine, piperidine, triethanolamine, triethylamine, thallous nitrate, or lead acetate.
