Title: Producing a protective coating on metal by cathodic coating
IPC: C25D11/38
Filed: 1963-06-10
Abstract: A tough protective coating is cathodically deposited on a metal base, e.g. of steel, zinc-electroplated steel, or aluminium sheet, from an aqueous solution of pH<1.5 containing a hexavalent chromium compound and a halogen oxyacid or a salt thereof.  The halogen oxyacid or salt which may be present in an amount of 1 to 200 g/l is typically perchloric acid, sodium perchlorate, potassium chlorate, or sodium or potassium bromate, while the hexavalent chromium compound which may be in a concentration of 10 to 300 g/l is typically chromic acid but may be a soluble chromate or dichromate together with sufficient perchloric or nitric acid to obtain the necessary pH.  Bath temperatures may be from 10 to 90 DEG C with cathode current densities up to 20 A/sq.dm. and treatment times of not more than 1 second.  The colour of the coating varies with its thickness, endures working without peeling and accepts paint, for which purpose a coating thickness corresponding to 2 to 3 mg/sq.dm. is sufficient. Before coating the metal is degreased and if rust is present it is pickled, and after coating it is subjected to an alkali dip in dilute sodium hydroxide or ammonia solution.

Patent GB-594350-A (GB)
Title: Composition of ice cream and method of making same
IPC: A23G9/34
Filed: 1944-11-22
Abstract: A small percentage (from .1 to .3 per cent.) of carboxy methyl cellulose (cellulose glycolate) and/or its salts is added to an ice cream mix which forms a gel to facilitate the production of overrun and to take the place of the usual gelatin or vegetable gums which tend to include dirt and bacteria to contaminate the mix.  The cellulose or its salts such as of sodium, ammonium or potasium are dissolved and added to the mix before or during freezing.  Owing to the absence of contaminating materials pasteurisation may be unnecessary.  The highest viscosity grade of the cellulose compound is preferred.  As an example, 5.5 lbs. skim milk powder, 55 lbs. milk, 25 lbs. of 35 per cent. butterfat cream, 14 lbs. sugar and 3 lbs. of sodium carboxy methyl cellulose are homogenized and mixed through a colloidal mill and frozen. The mixture may also contain 1 lb. of dry orange juice concentrated as set out in Specification 594,347, dissolved in 1 gallon of water.  This is homogenized with five gallons of ice cream mix.  Since up to .3 per cent. of sodium carboxy methyl cellulose was added to the orange juice before concentration as described in the above-numbered Specification no further addition of cellulose is necessary in the ice cream mix unless it is desired to increase the viscosity.  During homogenization the desired amount of air is incorporated to obtain the desired amount of overrun.  The longer the mix is treated in the colloidal mill or other homogenizer the greater will be the amount of overrun. In the same way, the juices or a combination of juices, of other fruits or vegetables may be added.

Abstract: 1486056 Winding side-by-side windings SOC ANON FRANCAISE DU FERODO 2 June 1975 [11 June 1974 28 Oct 1974] 23858/75 Heading D1J A device for winding cable 1 onto a drum 2, Figs. 1 and 2, such that a major portion of each turn 7, 8 of the cable lies in a plane normal to the axis of the drum, and such that there is a short oblique portion E, F between adjacent turns 7, 8 comprises a cable guide member 16 that is displaceable by means comprising a guide cylinder 18 bearing peripheral guide grooves 23 having portions of circular arcs joined by short oblique portions to shift the guide member 16 in a step-bystep manner along the drum 2 as the drum rotates, the circular arcs serving to keep the cable guide member 16 stationary during the major part of each revolution of the drum 2 and the short oblique portions of the grooves 23 serving to displace the cable guide member 16 by one step over a distance equal to the diameter of the cable each time the drum completes one revolution. In Figs. 1, 2 and 3 the guide member 16 includes a carriage with a nut 19 on a threaded shaft 20. The shaft 18 is driven by a chain transmission 22 at half the speed of rotation of the drum 2. In the periphery of the shaft 18 in a groove 23 in which there is engaged a feeler 24 carried by the bearing 17. As will be seen from Fig. 2 the groove 23 comprises a plurality of annular channels interconnected by cross-over channels. The feeler 24 is part of a reading head 25, Fig. 3, controlling a hydraulic motor 27 that drives the screw-threaded shaft 20. When the feeler 24 is in an annular channel no signal is sent to the hydraulic motor 27 and the shaft 20 does not rotate. When the feeler 24 is in a cross-over channel it sends a signal to the motor 27 that causes the shaft 20 to rotate in the appropriate direction to cause the bearing 17 to move into alignment with the next succeeding annular channel in the shaft 18. The cable 1 is thus traversed in a step-bystep manner onto the drum 2. The carriage 16 carries rollers 14, 15, Fig. 2, between which the cable 1 passes. In a second embodiment, Figs. 6 and 7 (not shown) the screw-threaded shaft 20 and nut 19 are replaced by a slidable bearing 19a that can be displaced by a double-acting jack (27a) supplied directly by a distributor controlled by the feeler 24. In a further embodiment, Figs. 8, 9 and 12, (not shown) the first turn that is wound on the drum is spaced from the end flange of the drum by a packing piece (30) in the shape of an interrupted ring having a thickness equal to half a diameter of the cable, the edges of the interruption being cut on the slant so as to serve as a support for the oblique portion of the cable between said first turn and the point at which the cable passes in through a window in a side flange of the drum 2. The drum 2 may have welded to its cylindrical surface hoops (36), Fig 12, that serve to position the turns of the first layer in correct array. The feeler 24 may form part of a magnetic or photoelectric reading head.
