Patent GB-475949-A (GB)
Title: Process for producing clear aqueous solutions of animal, vegetable or synthetic lipoids
Filed: 1936-05-25
Abstract: Clear aqueous solutions of lipoids are obtained by treating these in presence of water with a polyethyleneglycol ether of a fatty alcohol of high molecular weight under conditions which tend to cause a de-mixing or desolvatation of the solution.  Such influences are the addition of an electrolyte or a feeble acid or alkali, or of an organic solvent of the lipoid having a limited solubility in water, also heat with or without increased pressure. The de-mixing influence is preferably applied to an extent just insufficient to produce separation of the solution into two phases.  The lipoids may be of animal, vegetable, or synthetic origin, such as oils, fats, waxes, phosphatides sterols, and their derivatives.  Specified examples are triolein, oleic acid cholesterol ester, beeswax, cod liver oil, kephalin, lecithin, oleic acid, cholesterol, lipoids from tubercular bacilli, and lipoids from horses' serum.  Solvents suitable as de-mixing agents include hydrocarbons and their halogen derivatives and alcohols of high molecular weight, e.g. toluene, aniline, phenol, chloroform, heptyl alcohol, and nonyl alcohol.  The dispersion medium may be a physiological salt solution, yielding products suitable for percutaneous injections.  According to typical examples, (1) a physiological salt solution is heated in a closed vessel to 100 DEG C. with 2,5 per cent of kephalin and 6 per cent of polyether; (2) 1 part of triolein, 1 part of lecithin, 2 parts of polyether, 96 parts of physiological salt solution, and 1 part of aniline are boiled together for a short time and the aniline is then expelled by steam. A clear solution of the lipoid is obtained.ALSO:Clear aqueous solutions of lipoids obtained by treating these in presence of water with a polyethylene glycol ether of a fatty alcohol of high molecular weight under conditions which tend to cause a de-mixing or desolvatation of the solution.

Title: A device for the generation of a static and homogenous magnetic field
IPC: H01F7/20
Filed: 1961-04-26
Abstract: 917,842. Electromagnets. TRUB, TAUBER & CO. A.G. April 26, 1961 [May 2, 1960], No. 15044/61. Class 35. The flux between poles is rendered uniform over a central region by means of two or more straight conductors close to each pole face and lying so as to be tangents to a circle K whose radius is 0.365 times the pole spacing, Fig. 4. In its simplest form, for symmetrical fields, four linear conductors BCEF carrying a single current i in a closed square is used. The correction may be achieved by the use of only two parallel conductors, and to correct several errors, several such pairs of conductors may be placed at angles to one another. These pairs may form a square or regular polygon, and the currents in the pairs may be unequal. The orientation and position of the correcting system with respect to the poles may be adjustable. In a practical form, Fig. 9, the conductor pairs, e.g. a, b and c, d, are elongated loops made of printed circuit to secure the required flatness. In the form shown, the circuits may be printed on opposite sides of the backing sheet. In order to neutralize the reduction in the main field that the correcting conductors produce, additional conductors carry the same current at a greater spacing. Specification 838,160 is referred to.

Patent GB-1585345-A (GB)
Title: Electrical connector having displaceable sidewall terminal element
IPC: H01R4/24
Filed: 1978-04-18
Abstract: The electrical connector has a connecting part (10) which is in the form of an elongated groove with a U-profile and is inserted into a contact socket (34). The mutually opposite side walls (12, 14) are connected to one another at specific points by means of a base (16). Each side wall has an elastically deformable region (18) on which inward bends are arranged. The insulation of a conductor which is intended to be pressed in between such bends is cut into by means of inclined surfaces (28) of opposite inward bends. The inclined surfaces (28) have a cutting edge at their upper end for this purpose. Connected to the surfaces (28) at the bottom is a connecting part (29) which forms a flat rubbing surface which engages on the conductor. The lateral dimension of the connecting part in the elastically deformable region (18) exceeds the internal dimensions of the contact socket (34) so that, in the installed state, it is in pressing contact with the walls of said socket. A portion of the forces exerted during insertion of a conductor (C) is thus absorbed by the contact socket (34). <IMAGE>
