Title: An improved method of applying lubricants to bearings
Filed: 1944-07-12
Abstract: Lubricating greases are applied to antifriction bearings by immersing the bearing in a composition comprising 1/4 to 4 parts by weight of lubricating grease to 1 part by weight of a volatile solvent and thereafter heating the bearing to evaporate the solvent.  The solvents specified comprise petroleum or mineral spirits, paraffinic hydrocarbon solvents of boiling range 110 DEG -395 DEG F., aromatic hydrocarbon solvents of boiling range 200 DEG -412 DEG F., and safety solvents containing halogenated hydrocarbons, the hydrocarbon solvent known under the Registered Trade Mark "Varsol" is exemplified.  The greases may be alkali metal or alkaline earth metal soap greases or mixed base greases such as sodium-barium, sodium-aluminium, and particularly lithium-aluminium, and lithium-barium.  These may be of the usual soap-making fats or acids particularly stearin and hydrogenated fish oil acids.  Antioxidants may also be added such as zinc naphthenate and phenyl a -naphthylamine.  A drying oven heated to a temperature of 100 DEG -200 DEG F. may be used.  The dipping followed by the drying steps may be a continuous operation by loading the bearings or articles to be lubricated on to a conveyer.

Title: Improvements in or relating to the character and life of foam in foam-producing beverages
Inventor: SEGEL EDWARD
IPC: C12H1/14
Filed: 1960-04-25
Abstract: The character and life of foam in naturally or artificially carbonated foam-producing beverages is improved by dissolving high molecular weight polyethylene oxide in the beverage.  In the case of alcoholic beverages, the polyethylene oxide is preferably added after the completion of fermentation but it may be added during or before fermentation.  Polymers of ethylene oxide in the molecular weight range of two hundred thousand to over six million when present in a concentration of 40-80 parts per million are particularly suitable; the polyethylene oxide may be sheared to reduce its viscosity in aqueous solution, before being added to the beverage; e.g. a 1% aqueous solution may be stirred at 15,000 r.p.m. for 15 seconds.  A cobaltous salt, such as the chloride, citrate, sulphate, nitrate and acetate or their mixtures, may additionally be dissolved in the beverage, preferably in a concentration of 0.5 to 5 parts per million.  According to an example, a 1.34% aqueous solution of a high molecular weight polyethylene oxide (viscosity of a 1% solution about 3,000 centipoises) and a 0.134% aqueous solution of cobaltous chloride hexahydrate were added to beer; the final concentrations of the polymer and cobalt were 40 and 2 parts per million, respectively. The foam collapse times of beer thus treated and untreated beer were 7 minutes 10 seconds and 5 minutes 18 seconds, respectively. Another example is directed to the treatment of a carbonated soft drink.  A number of beverages are referred to.  Reference has been directed by the Comptroller to Specification 816,361.

[Also in Group XXXI] The steering wheel of a vehicle is mounted upon either an inextensible shaft or a shaft constructed in two relatively movable parts by an assembly comprising male and female collet elements, the coned part of the male collet element being contractible for clamping engagement with the steering shaft when the two elements are urged axially towards one another under the influence of a locking nut constructed separately from the female element and having an abutment face for co-operation with the male element for producing the clamping engagement. On an inextensible shaft 11, Fig. 1, the female collet element 13 is integrally joined to the steering wheel casting 12 and is splined for axial movement upon the shaft. The male collet 17 having radial slits in the coned portion is urged into contact, thus gripping the shaft, by a nut 19 threaded upon the female member and having an abutment face 21. As shown in Fig. 3, the female conical portion may be formed in a shaft 13 which is axially movable relative to the shaft 11 to which the wheel casting 12 is attached, the nut 19 with an abutment face 21 being threaded upon the shaft 13 and being capable of urging the male collet element into contact with the female conical portion causing it to grip the shaft 11.

[Class 100 (ii).] To enable a copper skin bearing an intaglio printing-surface to be readily stripped from its base after use, a layer of amalgam is applied to the base before the deposition of the copper and the copper is deposited thereon in an acid bath. As shown, an iron roller 1 is provided with a sleeve 2 of copper or other amalgamizable metal. The surface of the sleeve 2 is treated with a solution of mercury chloride in potassium cyanide to form a layer 3 of amalgam. A copper skin 5 is then deposited in an acid bath. The acid bath causes the formation of a thin film 4 of mercury sulphate which permits of ready removal of the skin, when desired, after slitting the skin circumferentially and longitudinally by knives 6, 7 respectively.
