Title: Process for the dewaxing of a wax-containing residual lubricating oil fraction
IPC: C10G73/04
Filed: 1962-03-13
Abstract: Wax-containing residual lubricating oil fractions are dewaxed by precipitation of the wax in the presence of at least one copolymer derived from a mono (2-, 3- or 4-) vinyl pyridine or a lower (C1-C8) alkyl substituted derivative thereof and from at least one ester of an aliphatic alcohol and acrylic acid or an alpha-substituted acrylic acid, followed by separation. The precipitation may be effected by chilling in the presence of a dewaxing solvent, such as a lower alkane, for example ethane, butane, or propane, or a polar solvent such as a ketone, for example acetone, methyl ethyl ketone, or methyl isobutyl ketone, with or without an aromatic hydrocarbon such as benzene, toluene, or xylene. The copolymers may be employed in an amount of 0.05-0.5% wt. of oil.  The copolymers may be added to the oil and subsequently the mixture combined with the dewaxing solvent. The average molecular weight of at least one of the copolymers may be between 5 x 104 and 2.5 x 106 and the mol. ratio of vinylpyridine type compound to ester(s) between 1 : 10 and 5 : 1. Preferably at least one copolymer in at least a terpolymer derived from two or three different esters. A large number of examples of suitable copolymer components is given.

Filed: 1918-06-12
Abstract: 154,239. Gerrard, A. J. June 12, 1918. Twisting wires together; shearing-adjuncts.- A bundling-machine comprises the following means for twisting the ends of the tying-wire together and for severing the tie from a main supply of wire. The twisting-devices are mounted in a head 24, and consist of three rotatable members 25, 26, 27 with radial slots to take the ends of wire, the middle member 25 being rotated to twist the wire ends together, and the side members 26, 27 being then rotated to aline the slots and release the wire. The member 25 is rotated by means of a pinion 28, Fig. 4, gearing with a segment 29 on a shaft 30 operated by a hand-lever 31. The members 26, 27 are rotated by means of segmental pinions 33, Fig. 3, carried in a shaft 32 and operated by a link 35 and a swinging arm 36 having a cam slot 38 traversed by a roller carried on an arm 39 on the shaft 30. The free end of the wire is held between a pivoted jaw 40 and a fixed jaw 41, Fig. 5. The jaw is normally held open by a spring latch 52, Fig. 3, which is released by hand to allow the jaw to fall and clip the end of the wire. At the end of the operation, a spring- controlled rod 45 is moved rearwardly by an arm 47 on the shaft 30 engaging a pin 46 on the rod, and an inclined surface on the rod opens the jaw 40 and engages it with the latch 52. A wire cutter 42 on the opposite side of the head is actuated by another arm on the shaft 30. A wire strainer consisting of a lever with two opposed pawls is mounted on the frame to draw the wire taut. The material is placed on a table carried by a rod which is raised by a treadle lever to compress the bundle and held by a. ratchet and pawl. The pawl is released by an eccentric after tying is completed to permit removal of the bundle.

Title: Process for the production of multi-colour pictures
IPC: G03C7/25
Filed: 1929-03-27
Abstract: 330,997. Jos-Pe Farbenphoto Ges. Feb. 28, 1929, [Convention date]. Photo-mechanical printing-surfaces.-Relates to the production of multicolour pictures by the dyeimbibition process, by applying in succession to a moistened paper sheet dyed gelatin reliefs which are produced from colour-record images each obtained by exposing a light-sensitive silvergelatin layer through its support, and treating the layer, after development, first with metal salts, such as salts of chromium or copper, to harden the gelatin in the presence of the developed silver, and then with water to wash out the unhardened gelatin. The invention consists in employing abnormally flat gelatin reliefs, each produced by staining, prior to exposure, a silver-gelatin layer of normal thickness in order to, restrict the depth of penetration of light into the layer. In the case of tricolour pictures for example, the reliefs employed are such that, if they were used singly in the production of black and white pictures, they would give only a third or less of the necessary contrast and depth. Reference is made to various processes of. producing flat gelatin reliefs from plates &c. coated with thin emulsion layers which may be coloured.

A tachograph comprises a rotatable plate 22 provided with a rod 24 for engaging as required either a hole 26 in a record disc 21 or a tube 29 on which is grouped a bundle of discs the rod 24 being threaded to receive a nut 27 adapted to grip the disc 21 or lock the tube 29 against the plate 22. The plate 22 has four equispaced concentric projections 25 and the nut 27 has a complementary circular groove 28 so that a single disc 21 can be firmly gripped to turn with the plate 22. The tube 29 for a bundle of discs is made longer than the thickness of the bundle by at least the sum of the thicknesses of the nut 27 and one disc and the thickness of the flange 30 of the tube 29 which is attached to the end disc is made greater than the height of a projection 25 so that a bundle can be fixed on the rod 24 by tightening the nut 27 without the projections 25 penetrating any of the discs. The number of projections 25 may be varied and if placed at different radii complementary grooves must be provided in the nut 27. The plate 22 and clockwork for driving it are mounted in the lid of a housing, itself mounted on the dashboard of a vehicle and containing three styli with driving mechanism for recording, speed, distance and running and stopping times.

IPC: B30B1/00
Abstract: 3947. Pistonless Hydraulic Press Co., and Beckwith, N. G. Feb. 17. Steam and other fluid-pressure presses. - Flexible-chamber fluid-operated presses are constructed with one chamber within another, so that the interior chamber may be submitted to a pressure greater than the flexible material will normally sustain. Fig. 1 shows a press comprising a chamber a arranged within the chamber b, and connected therewith by a valve e, which cuts off communication when the pressure in the chamber b exceeds a certain predetermined limit. The material of the chamber a is thus exposed to an interior pressure and an exterior pressure.

Title: Process for preparing protease resistent urokinase
Inventor: BLABER MICHAEL
IPC: C12N15/58
Filed: 1986-04-21
Abstract: Compsn. comprises a protease resistant single-chain urokinase (I). (I) may be prepd. by (a) providing nucleic acid encoding a protease-resistant amino acid sequence variant of single-chain urokinase, (b) transforming a host cell with the nucleic acid, (c) culturing the transformed host cell until the variant urokinase accumulates in the culture and (d) recovering the variant urokinase from the culture. (I) is produced by combining urokinase with an agent to complex with urokinase or by covalently modifying single-chain urokinase at sites of proteolysis. The target sites include Arg156 to Lys158 and, pref., the site at residues Lys135 to Lys136. Covalent modifications are accomplished by reacting native urokinase with derivatising reagents or by the recombinant synthesis of mutants having site specific substns., insertions or deletions of amino acid residues at target sites. Complexing agents such as antibodies bind to urokinase at the target sites or at flanking sites so that access to the sites by proteases is impeded or prevented.
