Filed: 1922-03-11
Abstract: 178,422. Udylite Process Co., (Assignees of Wissler, W. A., and Humphries, C. H.). April 9, 1921, [Convention date]. Cadmium, depositing; treating after deposition. -Wires, rods, spring strips and other articles of iron, steel or other metal are provided with a rust-resisting coating of cadmium by electrolysis of a basic or neutral solution of the cvanide using an anode of graphite, carbon or other insoluble and non-polarizing material. The articles are then washed and baked for some hours at a temperature of 150‹ C. to 200‹ C., or up to 250‹ C. if embedded in calcium hydroxide. They may be further plated with another metal such as nickel, after being cleaned with dilute sulphuric acid or cyanide solution. The electrolyte may contain from 1.25 to 15 per cent of cadmium and from 1 to 25 per cent of sodium cyanide. It is preferably prepared by first dissolving 25 gms. of metallic cadmium in hydrochloric acid to form a neutral solution or a corresponding quantity of the sulphate or chloride in water. If nitric acid is used to dissolve the cadmium, the solution is evaporated to dryness with hydrochloric acid. A solution of sodium or potassium hydroxide is added to the neutral solution until all the cadmium is precipitated and the solution is red to phenol phthalein. Sodium or potassium cyanide is then added until the cadmium hydroxide is redissolved. A slight excess of free cyanide is allowable. The solution is then diluted to the litre. The strength of the solution is maintained constant by adding cadmium hydrate. With an electrolyte containing 10.5 per cent of cadmium, current densities of 25 to 290 amperes per sq. ft. may be used. The articles may be pickled in single or mixed acids, washed, and scratchbrushed, before plating.

Title: Improvements in, and relating to an Installation for the Sterilization or Pasteurization of Commodities Packed in Containers
IPC: A23L3/04
Filed: 1967-02-16
Abstract: 1,151,966. Endless conveyers. STORK & CO's APPARATENFABRIEK N.V. GEB. 16 Feb., 1967 [9 March, 1966], No. 7509/67. Heading B8A. [Also in Division A2] An installation for the sterilization or pasteurization of beverages and foodstuffs packed in tins or glass containers comprises a treatment space with an inlet and outlet through which advances an endless conveyer, carriers for the containers being mounted on the conveyer, the said carriers being loaded and unloaded outside the treatment space and a device which indicates which containers have been in the treatment space for a period of time greater than desired due to an interruption of the conveyer. A suitable device comprises a drive 1 which is synchronized with the conveyer and drive a ring 8 of magnetic material or electromagnet, a number of rod mark members 6, each rod representing a carrier or a group of carriers, and being held by magnetic force in locations 9 of ring 8, and a motion mechanism 2 for generating periodic displacement of the rods 6 when the conveyer is interrupted, the drive of which mechanism functions independently of the conveyer. The mechanism 2 comprises a rotary cam 3 and rod 4 carrying a disc-shaped member 5. The member 5 is provided with a sector 10 of magnetizable material, disposed within which is a magnetizing coil 11. The length of arc A of sector 10 corresponds to the time the carriers are in the treatment space. During an interruption of the conveyer coil 11 is periodically energized during an upward stroke of the rod 4 such that rods 6 in arc A during each energization, are dragged upwards due to the created magnetic field being stronger than the force of ring 8. When the conveyer is moved normally again the rods 6 which were in arc A during the stoppage, will indicate after leaving arc A, by their position with respect to scale 12, which carriers have been longer than desired in the treatment space. The rods 6 are returned to their original position by periodically energizing coil 14 during a downward stroke of rod 4. In other embodiments, the rods 6 may be mounted on the outside of rotary disc, outside of which is a reciprocating ring, or the rods 6 may be arranged radially and moved radially outwards, e.g. by means of a nut and screw thread mechanism during a disturbance of the conveyer. The device may be used with the sterilizing apparatus described in U.K. Specifications 991,430, 1,041,177 and 1,000,175.

Title: A process for the separation of mixtures of higher molecular weight alcohols into components of differing melting points
Filed: 1954-03-16
Abstract: A mixture of alcohols containing 8-30 carbon atoms is separated into components of different melting points by dispersing in an aqueous medium and separating the dispersion, at a temperature such that both solid and liquid alcohols are present in a solid jacket centrifuge (i.e. one employing no sieve or filter), into a lighter phase consisting of the liquid alcohols and a heavier phase consisting of the aqueous medium with solid alcohols suspended therein.  The mixture may be ground or crushed prior to dispersing or the melted mixture is cooled with agitation, prior to or after mixing with the aqueous medium, whereby a suspension of solids in liquids is obtained.  Organic liquids, e.g. substituted hydrocarbons, alcohols, ketones, esters and carboxylic acids, particularly liquid alcohols obtained in the process, may be added to the aqueous medium, the alcohol mixture or the dispersion.  Other additions include electrolytes, e.g. sodium or magnesium salts or corrosion inhibitors such as nitrates and salts of phosphorus acids, protective colloids including synthetic polymeric compounds, and surface - active agents of anionic, cationic or non-ionic type.  Where temperatures below 0 DEG  C. are employed, anti-freeze compounds may be added.  Numerous examples of the various additions are given.  The aqueous medium is in general 0.5-5 times the weight of alcohols.  The solids separated in the said medium can be recovered after heating to melt them and the aqueous phase recycled.  The solid and liquid alcohols can be again treated at higher and lower temperatures respectively. Examples describe the separation of alcohols obtained from sperm oil, by hydrogenation of the methyl ester of coconut oil fatty acids or of fatty acids obtained by paraffin oxidation, and by oxo synthesis which are cooled with stirring from 30 down to 10 DEG  to 20 DEG  C. with water alone or containing one or more of the following: magnesium sulphate, sodium chloride, sodium sulphate, chromium sulphate, fatty alcohol sulphate, fatty alcohol polyglycol ether, dodecyl benzyl diethyl ammonium chloride, lauryl pyridinium sulphate, sodium alkyl sulphonate, methanol, and sodium cellulose glycolate.
