Title: Securing a wiper arm for a windshield wiper to a shaft
IPC: B60S1/34
Filed: 1959-02-13
Abstract: 854,803. Securing wiper arms on shafts. SWF-SPEZLALFABRIK FUER AUTOZUBEHOER G. RAU G.m.b.H. Feb. 13, 1959 [Feb: 19, 1958], No. 5009/59. Class 80 (2). A windscreen wiper blade is secured to a sheetmetal mounting 2 pivoted on a head 5 formed with an axially-grooved bore 11 receiving the splined end 12 of a shaft 1, the ends 131 of springs 13 on the head being pressed inwards behind the splined shaft end 12 by the side walls of the mounting 2 when the blade and the mounting are pivoted upwards about a pin 6 from the position shown for the wiper blade to lie against the windscreen. The ends 131 of the springs then prevent the head 5 andthe wiper blade from being pulled off the end of the shaft 1. When the wiper blade and the mounting 2 are drawn away from the windscreen and pivoted about the pin 6 to the position shown, the springs 13 fly out clear of the-end 12-of the shaft, so that the head 5 can be withdrawn therefrom. Either two springs 13, or a single spring of U-shaped cross-section, may be provided. A snap-over spring-and-link device 8, 9 either biases the mounting 2 to hold the wiper blade against the windscreen, or holds the mounting in the inoperative position shown.

Title: Process for the production of ion exchanger membranes
IPC: C08J5/22
Filed: 1956-02-17
Abstract: Ion-exchange membranes are made by reacting in the presence of formaldehyde, or substances liberating formaldehyde under the reaction conditions, a preformed membrane containing reactive hydrogen atoms capable of condensation with formaldehyde which membrane is made by reacting a halogen-containing synthetic polymer with an organic compound which contains a reactive hydrogen atom, and a condensation product of formaldehyde and an organic compound containing ion-exchange groups.  The membrane is preferably a fabric made from polyvinylidene chloride, polyvinyl chloride, or polytrifluochloroethylene fibres.  The organic compound which contains one or more reactive hydrogen atoms may be aniline, N-methylaniline, toluidine, anisidine, phenylenediamines, benzidines, ethylenediamine, di-ethylenetriamine, triethylenetetramine, monohydroxybenzenes and polyhydroxybenzenes in which the hydrogen of a phenol group is replaced by sodium.  Suitable condensation products are described in Specifications 474,361, [Group IV], 613,139, 720,002 and 783,450.  Exemplified condensates are (1) the reaction product of phenoxyacetic acid dissolved in sulphuric acid with 2,4-sodium benzaldehyde disulphonate and then condensed with formalin and further phenoxyacetic acid; (2) as (1) but diphenyl ether or naphthalene being added with the formalin and further phenoxyacetic acid; (3) the condensate obtained by reacting phenoxyethyl-trimethylammonium chloride, diphenyl ether, paraformaldehyde and sulphuric acid; and (4) the reaction product of sulphonated diphenyl ether, 40 per cent formaldehyde and paraformaldehyde.  In examples, the preformed membrane is made by (1) treating a polyvinylidene chloride fabric at 95-100 DEG  C. with phenol and sodium hydroxide; (2) reacting a polyvinylidene chloride fabric at 95 DEG  C. with a saturated aqueous aniline solution; (3) heating a polyvinylidene chloride fabric with polyethylene imine; and (4) heating a polyvinylidene chloride fabric in a melt of resorcinol and caustic soda solution.  The ion-exchange is generally made by pouring on to a sheet of glass on which the pretreated membrane is laid, a condensate containing free formaldehyde, covering with a second sheet of glass, and heating the assembly to 90 DEG  C.

Abstract: 876,975. Sampling liquids. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Jan. 19, 1960 [Feb. 16, 1959], No. 5280/59. Class 106(5) A device for taking samples from a stream of liquid over a period of time comprises a sampling tube 1 connected by a pipe 4 to a sampling bottle 2 sealed by an elastomer cap 6 and a second pipe connection 5 from the bottle to means for applying a steadilyi ncreasing partial vacuum to the tube the pipes 4, 5 having pointed ends to penetrate the cap 6. The pipe 5 leads from the bottle through a valve 11 to a reservoir 3 which has an outlet 9 connected to a high vacuum pump and a valved inlet 8 which is connected with a metered water supply and has an air inlet 12. In operation, the water level in the reservoir, is initially below the inlet 8, the base of the tube 1 is immersed in the stream of liquid to be sampled and the vacuum pump started with the valve 11 closed and inlet 8 open to admit air from the vent 12. The pump is then adjusted so that pressure in the reservoir is at atmospheric and the valve 11 is opened and water fed through the inlet 8 at a steady rate so that with the pump operating at its adjusted rate a slow stream of air is admitted through the inlet 8 and up through the water in the reservoir. By maintaining constant the water feed and vacuum pump rate, there is a steady increase in the partial vacuum in the reservoir and hence a steady lift in the tube 1. The rate of sampling can be varied by adjusting the water feed rate, and a number of sampling bottles 2 and tubes 1 may be connected to the reservoir 3 via a manifold.

Title: Improvements in or relating to braking devices
IPC: F16D57/04
Filed: 1936-02-24
Abstract: 471,117. Fluid - friction brakes. PROPELLO INVENTIONS, Ltd., and YOXALL, J. Feb. 24, 1936, Nos. 5536 /36, 10555 /36, and 4920/37. [Class 103 (i)] A brake for an aircraft wheel comprises a fluid coupling having an element connected or connectible with the wheel and an element connected or connectible with a non-rotating member of the undercarriage. The fluid coupling shown in Fig. 1, comprises an element 10 fixed to the wheel within which is relatively rotatable an element 9. Normally the element 9 rotates idly with the element 10. To brake the wheel a piston 4 is operated by fluid-pressure which moves a toothed ring- 7 into engagement with a toothed ring 8 on the element 9 and thus locks the element 9 to the stationary axle 1, fluid friction braking then being developed by the action of the fluid of the coupling on the relatively rotating elements 9, 10. A fluid operated hand brake 14 brings the machine to rest. A modified form of fluid friction brake comprises alternately arranged discs 32, 33, Fig. 4, in a channel 23. The discs 32 are notable with the wheel 11 and the discs 33 are keyed to the stationary axle. The discs have perforations adapted to register at certain relative positions of the discs, which perforations are traversed by the liquid contained in the chamber 23, from which liquid a shearing effect is produced by relative rotation of the discs. The fluid is normally contained in a chamber 39 and flows into the chamber 23 when the wheel rotates at sufficiently high speed through openings 36. In a modification of this disc arrangement the liquid is always contained in the chamber 23 and the discs 33 are adapted to be unclutched from the axle. The fluidpressure means in the axle may operate a clutch adapted to disconnect either series of plates from the wheel hub or axle. Two or more additional series of plates may be used. The fluid coupling may be used to operate a friction brake. Specification 414,641 is referred to.

The tube may be twisted in rope-like form between guide pulleys to assist in keeping the slit closed. The edges of the slit are formed with interlocking tongues and grooves, and partitions 12 are provided at intervals in the tube. Specification 444,472 is referred to.

Title: Improved process for the purification of uranium salts
Inventor: BRETSCHER EGON
IPC: C22B60/02
Filed: 1942-04-30
Abstract: Impurities are removed from uranium salts, particularly uranyl nitrate, by dissolving the salt in an organic solvent, adding a small quantity of water and then a further organic liquid which displaces water from the initial solvent to carry impurities into the separate aqueous layer formed, leaving purified uranium salt in the organic solvent phase. Alternatively no water need be added if the water of crystallisation is sufficient, on displacement to form an aqueous layer.  Suitable organic solvents are methylethylketone, acetone, ethyl or methyl alcohol, ether or cyclohexanone.  The displacing organic liquid may be xylene, benzene, toluene, cymene, tetraline, chlorobenzene, nitrobenzene or carbon tetrachloride.  An example refers to dissolving uranyl nitrate in methylethylketone until the solution density is 1.45, filtering and adding xylene to form an aqueous impuritycontaining layer.
