Title: Process of preparing lyo-phile products of fatty substances of any origin
IPC: A61Q19/00
Filed: 1929-02-14
Abstract: 329,305. Sandqvist, H., and Lindstr÷m, T. O. H. Feb. 14, 1929. Emulsions, making; ointments or salves.- Petroleum jelly, paraffin, lubricating oils, fatty oils and other substances of a fatty or oily nature are combined, preferably during heating, with 0.1-10 per cent of one or more phytosterins to form compositions capable of absorbing water, water solutions or substances such as glycerine, the absorbed substance being dispersed in the base. The products are applicable to the manufacture of ointments, medical and cosmetic salves, lubricants, paints, and food-products such as margarine. The phytosterins may be oxidized before addition or air may be passed through the liquified base during the addition in order to oxidize the phytosterins in situ. Examples refer to the addition of 3 per cent of a phytosterin to petroleum jelly, paraffin or lubricating oil, the mixture being heated, if desired, to 180‹-200‹C while stirring and passing air therethrough. The products are capable of absorbing two to three times their weight of water or water-solutions of substances such as glycerine, aluminium subacetate, silver nitrate or iodine. Petroleum jelly containing 50 per cent of a phytosterin is stated to be capable of absorbing four times its weight of water; in place of water, glycerine, aqueous alcohol or other substances may be absorbed. The preparation of salve bases, capable of absorbing water, water solutions or other liquids, by the addition to petroleum jelly, paraffin &c. of oxycholestrin or oleic acid is referred to.

Title: Improvements in or relating to modified polymers of ethylene
IPC: C08F8/50
Filed: 1942-04-22
Abstract: Modified polymers of ethylene, ranging from wax-like to grease-like and oily products, are obtained by subjecting polythene to heat treatment, in the absence of air or oxidizing agents, at a temperature above 290 DEG  C., preferably 330-600 DEG  C. for an appropriate time and preferably until no further pyrolysis occurs. Products of particular consistency may be obtained either by complete pyrolysis at the appropriate temperature, or by partial pyrolysis at a higher temperature; data correlating temperature, time and consistency are given.  Pyrolysis may be conducted as a batch, or as a continuous operation.  The treatment may be applied to a solution of polythene in a heat-stable solvent, sufficient pressure being maintained to prevent volatilization of the solvent.  Examples of batch processes are: (1) heating a polythene of molecular weight 17,000 for 2 hours at 400 DEG  C. to produce a hard wax; (2) heating the same polymer, in an evacuated vessel, at 600 DEG  C. for 4 hours, to obtain as distillate, an oily product suitable as a transformer oil; (3) heating a polythene of molecular weight 14,000 at 450 DEG C. for 3 hours to obtain a stiff grease, and of continuous processes; (4) forcing molten polythene, of molecular weight 14,000, through a tube heated to 450 DEG  C. under nitrogen pressure at a rate such that the material remains in the heated zone for 30 minutes; and (5) extruding polythene of molecular weight 12,000 through an iron tube heated to 550 DEG  C. at a rate such that it remains in the heated zone for 10 minutes to yield a tough wax.  Specifications 471,590 and 578,584 are referred to.

Abstract: 1493863 Radiographic apparatus SIEMENS AG 10 Feb 1975 [16 March 1974] 5649/75 Heading H5R [Also in Divisions G2-G3] Information from a data carrier 3 is recorded on to an X-ray film 13 in a cassette 5, the information being selectively recorded as an inverted image or a non-inverted image in dependence upon the direction of penetration of X-rays into the patient. The information is transferred from the carrier 3 via an optical system which includes a Dove prism 28 optionally movable into the optical path in dependence upon which direction the cassette 5 is manually inserted in a socket 4, the direction chosen depending upon whether the radiogram is p.a. or a.p., so that the recorded data is a mirrorimage or true image of that on the carrier 3 whereby when the film is viewed the viewer may assume that the direction of viewing is of the patient towards the viewer if he is able to read the patient's data. The prism 28 is moved by a solenoid 32 against a spring 33 into the optical path when the cassette is inserted in the socket 4 in the p.a. direction 36, the cassette moving a pivoted spring- loaded lever 14 anticlockwise to actuate contacts 20. If the cassette is inserted in the a.p. direction 35 contacts 19 are actuated which contacts are not connected to the solenoid 32, but either of the contacts 19, 20 when actuated operates a solenoid 21 for moving a permanent magnet 23 to open a protective light-tight ferro-magnetic coated window 12 in the cassette when the cassette is fully inserted in the socket 4, a flash lamp 30 connected in parallel with a capacitor 37 also being operated. The correct positioning of the data-carrier 3 is indicated by the carrier interrupting contacts 34. In a second embodiment, Fig. 3 (not shown), the Dove prism is connected by a cable to the lever for mechanical movement of the prism out of the optical path against a spring when the lever is pivoted anticlockwise by insertion of the cassette in the a.p. direction. The permanent magnet for opening the window in the cassette is moved by a servomotor. Alternatively, the Dove prism may be moved by an electrical motor which may also move the permanent magnet. The apparatus may be installed in an X-ray examination device, e.g. an X- ray target device, the data being recorded when the device is in a "readiness" condition, or during X- ray exposure, or immediately following X-ray exposure. The Dove prism and the flash lamp may be operated by a manually actuable switch having a neutral inoperative position.
