Title: Poly-n-acrylylpiperidine filaments
Inventor: SANDERS ARTHUR JOSEPH
Filed: 1960-12-06
Abstract: Filaments are made by the solution-spinning of poly-N-acrylylpiperidine.  Solutions of crystalline poly-N-acrylylpiperidine in chlorinated hydrocarbon solvents or mixtures thereof, e.g. methylene chloride, chloroform, tetrachlorethane, chlorobenzene, and mixtures of methylene chloride with either chloroform or chlorobenzene, may be wet-spun into any of the following coagulants:- acetone, aqueous acetone, tetrahydrofuran, methyl ethyl ketone, N:N-dimethylformamide, N:N-dimethylacetamide, cyclohexane and isopropyl alcohol. Chlorinated hydrocarbon solvents boiling below 70 DEG C. are preferred.  Alternatively, solutions of crystalline poly-N-acrylylpiperidine in lower fatty acids, e.g. formic or acetic acid, may be wet-spun into water or aqueous alkali. Coagulated wetspun filaments may be stretched in a hot glycerol bath at, e.g. over 60 DEG C., dried, wound-up, and then further stretched, e.g. over a hot plate at temperatures above 130 DEG C.  In an example, a 20% w./v. solution of poly-N-acrylylpiperidine in methylene chloride is spun into a coagulating bath of N:N-dimethylformamide at 20 DEG C., and the coagulated filaments are drawn 100% in a glycerol bath at 120 DEG C.  After drying, the filaments are further drawn at a draw ratio of 2:1 over a hot plate at 180 DEG C.  Crystalline poly-N-acrylylpiperidine may also be dissolved in chloroform or methylene chloride and dry-spun into hot air at a temperature above 40 DEG C.  In an example, a 40% w./v. solution of poly-N-acrylylpiperidine in methylene chloride at 38 DEG C. is dry-spun into air at 44 DEG C.

Title: Process for the isomerization of n-paraffins into iso-paraffins
IPC: C07C5/27
Filed: 1962-11-06
Abstract: In the isomerization of n-paraffins in the presence of a liquid Friedel-Crafts catalyst wherein spent catalyst from the reaction is extracted with feed hydrocarbons to dissolve active constituents from the catalyst, the feed is separated into first and second portions, the first is heated to a temperature such that on recombining with the unheated second portion the desired reaction inlet temperature is achieved, the heated first portion is used to extract the spent catalyst and is then passed with the second portion to the isomerization zone.  The reaction temperature may be 20-120 DEG  C. and the feed is preferably at least 8 DEG  C. cooler than the inlet temperature, at least 40% of the feed forming the first portion. Up to 3% mol. of hydrogen may be added, the total pressure being 1-22 atm. abs.  The catalyst may be aluminium chloride or bromide preferably used in the presence of hydrogen halide and preferably mixed with another halide, e.g. antimony trichloride.

Abstract: 424,710. Printing-machines. GERPE, M. F., 371, Calle 25 de Mayo, Temperley, Buenos Aires. Nov. 24, 1933, No. 32940. [Class 100 (ii)] Rotary machines for printing tickets.-A machine for printing or dating railway or similar tickets comprises a pair of drums 3, 7, one drum 3 bearing the printing-types and the other 7 serving to feed the tickets, the drums being operated by a toothed sector 15 which meshes with a gear-wheel 19 associated with one of the drums, is normally kept in an end position by a spring 12, and is made to effect a partial rotation in the opposite direction by means of a lever 10 coupled to the shaft 16 of the sector 15, the dating-drum 3 receiving during each movement a supply of ink from one or more inking-rollers 1 arranged in a casing 24 resting on the machine. The drums are mounted in bushes in the side walls of the casing 20 and are geared together. Tickets are guided between the drums by a pair of inwardly directed members 30, and are issued through a slot 31. The inking- rollers 1 are coated with felt, &c., and are mounted on removable spindles 2 which pass freely through one side of the casing 24 and screw into the other side, knurled heads being provided to facilitate screwing or unscrewing. Impression adjustments.-The casing 24 forms a continuation of the casing 20, with which it co-operates to form a bearing for the dating- drum 3. It is pivoted at 24<a> at one end, and is resiliently retained at the other end by a screw 25 adapted to pass through a recessed boss 25<a>. A spring 28 interposed between the bottom of the recess in the boss and a collar 26 on the screw resiliently presses the casing 24 against the casing 20, so that the casing 24 can therefore yield upwardly when the insertion of a ticket between the drums 3 and 7 exerts a lifting action upon the drum 3. A screw 27 permits limited longitudinal movement of the screw 25.

Abstract: 1388517 Comparative A P PEDRICK 19 Sept 1973 44031/73 Heading G4M [Also in Division H1] An apparatus for making comparisons between digitally-encoded stored information and digitally formulated search questions is designed for use by Patent Offices, preferably on a world-wide basis, for mechanized information retrieval. Fig. 2 depicts the essential element of the apparatus, which is effectively a multiposition switch. Each of the rods 2 in each of two opposed sets of parallel rods is advanceable in discrete steps, the interengagement of spring- loaded balls 3 with sockets 3<SP>1</SP> on the rods locating the rods in their set positions. As is evident from the drawing when the extent of advancement of all the rods in the left hand set, as denoted by a scale of ten number defining the number of steps made by successive rods for that set, is the complement of the number similarly representing the state of the rods of the right-hand set, then electrical contact is made by the end-to-end juxtaposition of all corresponding pairs of rods. Evidently, if one of the rods is advanced by less than the distance required to meet its corresponding facing rod, there is a gap between them. In addition, as depicted in Figs. 4(A) to 4(C) (not shown, but see Division H1), the arrangement of electric contact making elements in the rod ends is such that, should one of the rods be advanced by more than the amount necessary to just meet its corresponding rod, the circuit made in the "correspondence" position is broken. A very large number of possible comparisons can be provided for by replication of the system shown, preferably in a helix configuration similar to the structure of a DNA molecule (Figs. 1 and 2, not shown). The intended manner of use is as described in the case of the apparatus having a similar function as described in prior Specifications 1,280,928 and 1,333,194, and, as in these patents, it is envisaged that several Patent Offices would record document-classification information in the system in accordance with an internationally-agreed coding and that search questions could then be addressed from anywhere in the world to the system. In particular, the stored information could be located in a quasi-static earth satellite addressable by radio from the ground.
