Abstract: 888,565. Windscreen wipers. O'SHEI, W. E. May 14, 1958 [May 20, 1957], No. 15939/57. Class 138 (1). A windscreen wiper consists of a squeegee element 1 having flanges 2 on each side of one edge, in which are formed grooves 3 containing flexible strips 4, and a pressure distributing holder extends along the back of the squeegee and consists of yokes 6 and 6a connected by a bridge piece 9. The ends of the yokes have fingers 7 and grip the squeegee in order to prevent the strips 4 from leaving the grooves 3. The squeegee is provided with enlargements 12 and 12a which hold it in position relative to the yokes. The rivets 8, on which the yokes 6 and 6a are pivoted, are resiliently mounted, in the bridge 9.

Patent GB-612494-A (GB)
Title: Sway braces for pipelines or like parts
IPC: F16L3/205
Filed: 1946-05-27
Abstract: 612,494. Vibration-dampers. GENERAL SPRING CORPORATION. May 27, 1946, No. 15982. Convention date, Aug. 4, 1945. [Class 108 (iii)] [Also in Group XXVIII] A sway brace, for connecting a pipeline to a fixed support so as to restrain vibratory and inertial movements, but to allow limited slower or persistent movement of the pipeline relative to the support, comprises spring means for applying a steadying force to the pipeline and means for connecting the spring means to the pipeline and to the support, the connecting means including a coupling having members which are normally interengaged so that the coupling will transmit the steadying force for restraining vibration and inertial movements and which are releasable to render the coupling inoperative and permit free adjustment between the members for accommodating the limited movement of the pipeline without the latter being under the action of the spring. Figs. 1 and 2 show the invention applied to pipelines carrying fluid subject to temperature changes. The pipe 14, Fig. 2, is connected to a fixed support 16 by a number of spring-sway braces 10 of the type described in Specification 565,189 and a rod and sleeve coupling having expansion or shrink engagement. Fig. 1 shows a form of the invention for use with high temperature pipelines the materials of the rod 24 and sleeve 20 being chosen with the rod having the highest coefficient of thermal expansion so that, at operating temperatures, the rod will expand and be gripped by the sleeve. A similar arrangement but with shrink engagement of sleeve to rod may be used for refrigerant pipelines. Means may be provided for heating one of the parts of the coupling so that it will expand away from the other part when a substantial temperature change takes place in the pipeline thus relieving stresses in the pipeline by disconnection of the coupling. When readjustment is complete, the coupling members re-engage. Fig. 8 shows an alternative arrangement in which a toothed connection replaces the rod and sleeve. A rod 24d is attached to the spring and carries a solenoid 75 the plunger of which is connected to bellcranks 76 pivoted on the rod and each carrying a roller 78. The rod 24d is toothed and engages teeth on a rod 80 attached to the fixed support 16e. Yokes 82 are welded to rod 24d, these yokes carrying bearing plates 84 which are pressed against rod 80 by springs 86. The springs are sufficiently stiff to hold the two rods 24d and 80 engaged against all normal vibration but are adapted to be deflected by a pull of the solenoid on the cranks 76. The solenoid may be controlled by a mercury switch 97 which senses drift of the mean or relaxed position of the apparatus. Specification 575,385, [Group XXVIII], also is referred to.

[Classes 2(iii) and 15(ii)] Arylides of 2:3-oxynaphthoic acid are made by condensing 2:3-oxynaphthoic acid or a functional derivative thereof with an aminochrysene or an aminopyrene. In examples (1)-(3) 2:3-oxynaphthoyl chloride is condensed in presence of pyridine with 3-aminopyrene, 2:8-diaminochrysene (made by dinitration and reduction of chrysene) and 3:8-diaminopyrene (made by dinitration and reduction of pyrene). Azo dyes are made by coupling the above arylides with diazo compounds containing no groups which would render the dyestuff soluble in water in substance or on the fibre. The diazo compounds may be used in stabilized form or in the form of N-nitrosamines or diazoamino compounds ; these nitrosamines and diazoamino compounds may be used in admixture with the arylides or their alkali salts as preparations. The dyes may be used for colouring lacquers and varnishes. In examples (4) diazotized 2:5-dichloraniline is coupled with the product from 2:3-oxynaphthoic acid (2 mols) and 2:8-diaminochrysene) (1 mol) ; (5) cotton is impregnated with the arylide from 2:3-oxynaphthoic acid (2 mols and 3:8-diaminopyrene (1 mol) and developed with diazotized o-nitroaniline, or (6) with 2<1>-3<1>-oxynaphthoyl-3-aminopyrene and developed with diazotized 1-amino-2-methoxy-5- chlorbenzene. A table of further components is given. The Specification as open to inspection under Sect. 91 comprises the manufacture of arylides of o-oxycarboxylic acids by causing an ooxycarboxylic acid or a functional derivative thereof to react with an amine derived from a hydrocarbon having four angularly fused 6-membered rings and the manufacture of azo dyes therefrom in substance or on the fibre. This subject-matter does not appear in the Specification as accepted.

Abstract: Resinous products are obtained by condensing abietinols or hydroabietinol with polybasic carboxylic acids, their anhydrides, chlorides or amides in such proportions that the product contains at least one carboxylic acid or carboxylic acid chloride or amide group per molecule.  Suitable polybasic acids include oxalic, maleic, citric, diglycollic, malic, adipic, phthalic, hydrogenated phthalic, methylenetetrahydrophthalic terephthalic, diphenyl dicarboxylic, naphthalene-di- or -tetracarboxylic acids and the tribasic acids obtainable from maleic anhydride and colophony according to Specification 355,281.

Abstract: 471,620. Preserving meat. HIRSCHMANN, O. June 13, 1936, No. 16571. [Class 49] [Also in Group XVIII] Apparatus for preserving meat by injection of brine or other preservative liquid consists of a container b and a measuring vessel d for the liquid which are in direct communication by a pipe h, the flow of the liquid into the vessel d being effected and regulated by supply of compressed air through a pipe r and a reducing valve s to the container b. A pipe k supplies compressed air from container b to the vessel d to expel the liquid therefrom through a cock i to which the injection needle is connected, the pipe k having a three-way valve l which also enables the vessel d to be connected to atmosphere while it is being filled from container b through pipe h. As shown, two containers b, c, Fig. 2, and their measuring vessels d, e, are supported on a frame a with a common supply of compressed air from a vessel q to each container through a control valve v, w. A device for measuring the supply of liquid from the vessel d, which is made of glass or other transparent material, consists of a number of similar rods y, Fig. 5, pivoted on a vertical shaft x and provided at their ends with indentations z each half the depth of a rod. The shaft x is carried by arms 2 on a sleeve 3 adjustably mounted and fixed by a screw 4 on one of a pair of supporting columns t between the base g and cover f of the vessel d. The amount of brine used is determined by the weight of the piece of meat, the width of each rod y corresponding for example, to a half a kilogram and of each indentation y to a quarter of a kilogram, as many. rods as correspond with the weight of the meat being swung in against the vessel d. Manometers o, p indicate the pressure in vessel d and container b.
