Title: Improvements in and relating to paper-making processes
Inventor: HOEL LEROY W
IPC: D21H19/82
Filed: 1958-05-28
Abstract: 824,556. Mineral-coated paper &c. KIMBERLEY-CLARK CORPORATION. May 28, 1958, No. 17016/58. Classes 96 and 140. In coating a web of paper with a mineral coating containing a protein adhesive, the first coating applied includes a mineral pigment, a non-proteinaceous adhesive and an agent, e.g. a formaldehyde donor material, for rendering protein adhesive insoluble, and after drying a second coating containing mineral pigment and the protein adhesive is applied. According to an example, to a mixture of 93 parts clay and 7 parts TiO 2 , there was added 28 parts of a hot dispersion containing 25 parts starch and 3 parts melamine-formaldehyde resin; the pH of the mixture was adjusted to 8.0 using alkali and a small quantity of a dispersing agent, e.g. sodium hexametaphosphate was then added. The resultant coating mixture was diluted with water to a solids content of 54% and applied to both sides of a paper web at a rate of 7 lbs. per ream per side. A second coating mixture was prepared by addition of 13 parts casein and 9 parts concentrated ammonia solution to a mixture of 81 parts clay, 9 parts TiO 2  and 10 parts calcium carbonate. After addition of small quantities of dispersing agent and of alkali to give a pH of 8.5 to 9.5, 2 parts latex solids, 1¢ parts sulphonated tallow and a small amount of a foam inhibitor were added and the mixture was diluted with water to a solids content of 54%; the coating mixture was applied to the paper, after the first coating had dried, at a rate of 6.5 lbs. per ream per side. The coated paper was then passed through heated calendering rolls.

Title: Improvements relating to wind screen and like cleaning devices
IPC: B60S1/34
Filed: 1937-06-18
Abstract: 497,366. Windscreen - cleaners ; securing wiper arms on shafts. OSHEI, W. E., and TRICO-FOLBERTH, Ltd. June 18, 1937, No. 17040. [Class 138 (i)] [Also in Group XXIV] The wiper arm is secured on the motor shaft by means of a sleeve on the arm and a split collar, tightening of a nut causing coacting inclined surfaces to tighten the collar on the shaft. As shown in Fig. 2, a sleeve 13 to which the wiper arm is pivoted has an inclined surface 15 co-operating with the inclined outer surface of a split collar 20 which is slipped over the end of the motor shaft 14. When a nut 17, formed with a recess 19 to receive the end of the shaft, is screwed into the sleeve 13, the collar 20 is moved axially and tightened on the shaft. The collar has a liner of harder metal and is held from rotation on the shaft by a key 22. The split collar and nut may be secured permanently on the wiper arm. In modifications, the inclined surfaces are formed on the collar and nut. In other modifications the collar is provided also with a tapered inner surface, co-operating with an inclined surface on the shaft. In another modification, the collar has an internal rib co-operating with a circumferential groove on the shaft. In Fig. 6 the collar 132 is formed of soft metal so that it binds on the tapered end of the shaft when the nut 17 is screwed in. It can be forced off the end of the shaft, when required, by screwing in a screw 34.
Patent GB-774052-A (GB)
Title: Method and device for the production of energy from exothermal chemical of nuclear reactions
IPC: F24V30/00
Filed: 1955-06-14
Abstract: <PICT:0774052/III/1> A temperature of the order of 106 to 109 degrees K to promote nuclear or chemical reactions is obtained at the centre of a hollow sphere by producing spherical pressure shock waves. These shock waves are produced by energizing electromagnets 2 spaced from the steel sphere 1 or electrostatically, Fig. 3 (not shown), by a negative charge on a hollow metal sphere surrounding a hollow insulating sphere.  The frequency and amplitude of the shock waves are controlled at 8, 7, so that resonance is achieved and the temperature and pressure at the centre of the sphere is regulated. Hydrogen admitted at 10 is converted at the centre of the sphere into helium, removed at 11, and the heat generated is utilized by a heat transfer fluid admitted at 29 to a space surrounding the sphere 1 and expelled at 30.  In a modification, Fig. 2 (not shown), the electromagnetic impulses are transmitted to the metal sphere through a liquid to ensure that a good spherical wave is set up.  This liquid, water or mercury, may be used for heat transfer.

Abstract: 322,797. Carrier Engineering Co., Ltd., and Robertson, K. J. R. June 13, 1928. Fats and fatty oils, extracting by solvents.- Grease is removed from metal and other articles by immersing them in or passing them through a vapour solvent for the grease while they are at a temperature below that of condensation of the vapour, so that the vapour condenses on the articles and dissolves the grease which falls off in solution and leaves the articles dry. Vapour is regenerated from the resulting solution, and the grease and dirt are discharged. In the apparatus shown, the articles 4 are passed through vapour 7 by means of a conveyer 2, the vapours being admitted through nozzles 8, and the liquid and grease being passed through pipes 10, 11 to thermostatically heated stills 12, 13 having curved bottoms. Coils 20 are provided for cooling the vapour in the upper part of the chamber. In a modification, the condensed liquid is vaporized by means of heating pipes 26 which may be thermostatically controlled. After cleaning, the articles may be passed by the same or another conveyer through a hot air chamber to remove the last traces of solvent. Specifications 278,061 and 314,912 are referred to.

Title: Complex cobalt salts of carboxylic acid hydrazides
IPC: C07D213/86
Filed: 1954-06-16
Abstract: A complex cobalt salt of a heterocyclic carboxylic acid hydrazide is obtained by reacting a heterocyclic carboxylic acid hydrazide or salt thereof, e.g. the hydrochloride, with a cobalt salt in a liquid medium, e.g. water or alcohol, in which the reactants are soluble. Specified hydrazides are pyridine-4-carboxylic acid hydrazide, thiophen-2-carboxylic acid hydrazide, salicylidenepyridine - 4 - carboxylic acid hydrazide, and cyclohexylidenepyridine-4-carboxylic acid hydrazide and specified cobalt salts are the acetate, sulphate and chloride.  In examples (1) pyridine-4-carboxylic acid hydrazide and cobalt sulphate (CoSO4) are separately dissolved in the minimum amount of water at about 50 DEG  C. and the two solutions mixed together in a flask to yield the complex cobalt salt which separates out on standing; (2) two mols. of thiophen-2-carboxylic acid hydrazide and one mol. of cobalt acetate are shaken together in absolute alcohol for 24 hours after which the mixture is filtered and the filtrate evaporated to leave the complex cobalt salt.  In this example the acetate may be replaced by another cobalt salt soluble in the reaction medium and any of the above specified hydrazides may be used instead of thiophene-2-carboxylic acid hydrazide.  The products are stated to be active against tuberculosis.
