Title: A process for separating paraffins from hydrocarbon oils by treatment with urea
IPC: C10G31/06
Filed: 1959-09-04
Abstract: In the separation of paraffin from hydrocarbon oils by urea adduct formation, the adduct is obtained in an easily separable, granular form by treating the oil with urea in the presence of a urea solvent and an oil solvent and controlling the concentration and proportion of the urea solution and the temperature of the mixture during or after adduct formation to obtain a granular adduct.  Long lists of urea and oil solvents are specified, preferred being water or lower alcohols and chloro- or chloro-fluoro-hydrocarbons respectively. Upper and lower limits of temperature are given at various urea concentrations in water and proportions of urea solution for adduct formation with a spindle oil, kerosene, straight run gasoline and a reformed gasoline in the presence of methylene chloride as oil solvent.  If conditions during adduct formation result in a pasty emulsion a granular form can be obtained by lowering the temperature or increasing the proportion of urea present, e.g. by adding solid urea; the temperature may be lowered by evaporating part of the oil solvent.  If on the other hand a powdery adduct is formed, the temperature is raised or urea solvent is added.  In a preferred embodiment the urea is added in two stages observing the conditions for granular adduct formation in each.

Title: Method for preserving meat
IPC: A23B4/08
Filed: 1966-07-07
Abstract: According to the invention, hide removed from a decapitated and disembowelled animal, e.g. bovine animal, carcase, which, before removal of the hide, has been sprayed inside and outside with a preservative such as an aqueous 5% solution of sorbic acid or potassium sorbate, or an aqueous 7% solution of sodium bicarbonate or sodium chloride, then allowed to hang to attain a state of rigor mortis and put into "chilling" or "freezing" cold storage, then taken out of cold storage and allowed to thaw, until at least the hide has thawed (see Division A2), can be tanned with greater facility and simplicity than hide cured by know methods.ALSO:To prevent deterioration of a meat carcase during "chilling" or "freezing" cold storage, an animal, e.g. a bovine animal, is slaughtered and, before its carcase is put into cold storage, it is decapitated in such a manner that the strip of hide which covered the rear part of the head is retained on the carcase, together with the remaining portion of the hide.  The lower portions of the legs are then removed and the carcase is opened from the abdomen to the chest, and viscera are removed.  The inner part of the carcase is then washed thoroughly clean with a spray of warm water and dried, as by friction.  The carcase is then allowed to cool, e.g. in a current of air, and sprayed inside and outside with a liquid preservative, preferably applied at a temperature between 70 DEG  and 80 DEG  F.  Suitable preservatives are: an aqueous 5% solution of sorbic acid or potassium sorbate, and an aqueous 7% solution of sodium bicarbonate or sodium chloride. The resulting carcase is allowed to hang to attain the state of rigor mortis, before being put into cold storage.  When the carcase is taken out of cold storage the hide is removed after at least the hide has thawed, and the resulting meat, e.g. beef, is found is have retained its red colour.

Title: Polarised electro-magnetic tripping device for an electric switch
IPC: H01F38/30
Filed: 1952-12-04
Abstract: 719,917. Electrically tripped switches. AKT.- GES., BROWN, BOVERI & CIE. Dec. 4, 1952 [Dec. 29, 1951], No. 30766/52. Class 38(5) In a polarized electromagnetic tripping device, an armature is rotated in one direction by reverse current and in the other direction by forward excess current, rotation in either direction producing tripping by means of linkage systems such that a tripping catch is always moved in the same direction. In the Figure, a polarizing coil 2 sets up a constant magnetic field in the armature 5 and magnetic yoke 1, as indicated by full lines, and the current in bus-bars 3, i.e. the protected circuit, when flowing in one direction sets up the magnetic fields indicated by dotted lines. When the latter current is sufficient, the resultant field in the lower left hand pole piece and the upper right hand pole piece is able to rotate the armature 5 in an anticlockwise direction and by means of the left-hand linkage 6, 7, 10, rotate a catch 12, to release a switch lever 13. Should the current in the bus-bars 3 reverse, the armature is turned in a clockwise direction and through the righthand linkage 6, 7, 10<SP>1</SP> rotates the catch 12. The connections of the linkages to the armature 5 and catch 12 are such that when the armature rotates in one direction to move one linkage no movement is transmitted to the other linkage. The current settings are determined by setting the initial tensions of springs 8 which bias the links 7 against stops 9, the stops being adjustable so that the initial position of the armature may be set to permit response to low reverse currents.
