Patent GB-262827-A (GB)
IPC: B44C1/10
Abstract: 262,827. Lampen-und Metallwaren- Fabriken R. Ditmar Geb. Br³nner Akt.-Ges., (Assignees of Dornan, A.). Dec. 14, 1925, [Convention date]. Ornamenting. - A process for applying thin reflecting metal coatings to the surface of flexible backing material consists in impregnating the latter with a binder such as resin, shellac, celluloid, or gum which softens under heat and then applying it under pressure, with simultaneous heating, to the foundation plate to which the metal coating has been first applied. The impregnation of the backing material may be effected by spreading a thin layer of an emulsion comprising gelatine or celluloid. a filler such as zinc oxide or talcum, and gum, glycerine, or wax, on the surface of the plate which bears the reflecting coating, the backing material being pressed on before the binder is dry. Alternatively a thin layer of the surface of the backing material may be dissolved or made viscous, and that surface pressed on to the metal coating upon the foundation plate, heated rollers being used if necessary. The surface of a celluloid backing may for example be made viscous by means of glacial acetic acid. A preliminary backing of metal may be applied to the reflecting coating by electrolysis, after which the flexible backing is applied as described, and the finished sheet peeled off the foundation plate. The backing may be provided with pictures or wording, for example advertisements, by printing or otherwise, which become visible when light is passed through the mirror.

Title: Process for the production of acetone-formaldehyde condensation products
Inventor: WAAG THEODOR
IPC: C07C45/75
Filed: 1962-07-13
Abstract: Acetone-formaldehyde condensation products which contain 1 to 4 methylol groups per molecule are produced by a two step condensation of acetone and formaldehyde in the presence of an alkaline condensation catalyst, the first step being performed at pH 8-9 and 0 DEG  to 20 DEG C. and the second at pH 10-12 at 60 DEG  to 100 DEG C. The pH required for said second step may be obtained by adding more alkaline catalyst on completion of the first step.  The number of methylol groups per molecule is varied by adjusting the equivalent ratios of the reactants. Examples illustrate the preparation of condensation products having 3.7 to 3.8 and 1.9 to 2.1 methylol groups per molecule.  Specifications 361,597, 361,686 and German Specification 223,207 are referred to.

Abstract: 537,816. Metal phenates. STANDARD OIL CO. OF CALIFORNIA. Oct. 3, 1939, No. 27128. Convention date, Oct. 4, 1938. [Class 2 (iii)] [Also in Groups III and XIII] The properties of lubricating oils in respect of resistance to heat deterioration, decomposition causing piston ring sticking and corrosion of bearings are improved by the addition thereto of a metal phenate with a phenolic radical having more than 10 carbon atoms. The preferred phenates are those containing alkayl groups. Metals mentioned include sodium, potassium, beryllium, calcium, strontium, barium, magnesium, zinc, cadmium and aluminium. Specific compounds mentioned include sodium lauryl phenate, sodium cetyl phenate, calcium lauryl phenate, calcium cetyl phenate, calcium diamyl phenate, calcium heptyl phenate, calcium p-tertiary amyl phenate, calcium mono-chlor amyl phenate, calcium p-cyclohexyl phenate, aluminium lauryl phenate, aluminium di-cetyl phenate, magnesium cetyl phenate, barium cetyl phenate and calcium cetyl cresylate. Examples are given of the preparation of alkyl phenols from phenol and butene polymers by the addition of sulphuric acid to a mixture of phenol and the polymers followed by heating in an autoclave. The apparent molecular weight of the product depends on the exact composition of the polymers used and the degree of condensation. From products obtained by this process of different apparent molecular weights phenates of calcium, sodium, aluminium, magnesium and barium and prepared. An alkyl phenol is also produced by the addition of sulphuric acid to a mixture of cresylic acid and olefine polymers containing an average of 14 carbon atoms per molecule. The compound so obtained is reacted with calcium carbide to form the calcium salt which is used according to the process of the present invention.

Title: Improved method of and apparatus for removing gases from milk or cream or other liquids
IPC: A01J11/04
Filed: 1932-09-30
Abstract: In the pasteurization of milk, cream, or other liquids, gases are removed from the liquid by passing it as a film with a free surface over a series of moderately inclined surfaces 5, 6 in a closed chamber 1, successive surfaces having progressively increasing and decreasing surface areas and being curved transversely to the direction of flow of the liquid, e.g. being formed of hollow cones, successive cones being inverted.  The liquid is subjected during flow to a partial vacuum which is insufficient to cause ebullition, and is finally cooled.  As shown, the liquid coming from a heat exchanger in which it is partially pasteurized enters chamber 1 through an inlet 2 arranged above a spreader 3 with perforations 4 through which the liquid passes to the uppermost cone 5.  The cones may be detachably supported on one another by <PICT:0407743/III/1> marginal webs 17, the lowermost one being supported on lugs 16. Central and peripheral passages 18, 20 allow escape of the gases which pass off through an orifice 11 connected to vacuum.  Steam or an inert or neutral gas may be injected into the liquid from a perforated pipe 12.  The chamber may have a removable cover 14 with inspection windows 13.  The liquid leaves through an outlet 9<a>.  The surfaces over which the liquid flows may be matt or roughened, e.g. unpolished or sandblasted aluminium or other metallic surfaces to increase the surface area.

The paste passes through the aperture 4 to give a part 6 within connected by a core 7 to an outer cap 5 and this is allowed to dry in air and is then baked at 150 DEG  C. for 30 minutes and the temperature then raised to 500 DEG  C. for 20 minutes to burn off the organic material and fuse the paste glass to the glass of the tube 1, either in a furnace or by flame-heating the tip. The resultant porous seal is lightly ground to make it vacuum tight.  A second coating is then applied, after which a cadmium sulphide crystal may be soldered to the silver of the seal.
