Title: Apparatus for producing patterns in machines employing pattern cards
IPC: D03C19/00
Filed: 1927-03-07
Abstract: 291,534. Bree, E. van. March 7, 1927. No Patent granted (Sealing fee not paid). Jacquards; cards, punching.-The selection of the pattern in looms, card-punching machines, &c. is effected by electrostatic forces. As applied to looms current is supplied from the negative pole of a source of electric current to holders for semiconducting members combined into the form of a beam 18 moved up and down in contact with weighted insulated healds 1 hung on conducting wires 2 having parts 3 slidable up and down in U-form iron bands 4, arranged to form a beam 17 and to which current from the positive pole is supplied through wires 9. These are combined into a brush 19 and contact, where allowed, by pattern cards 11 arranged in endless band form with a tinfoil insert connected up through a resistance to the positive pole. The Johnsen Rahbeck effect is set up between the moving semiconducting members and the positively charged wires, whereby the friction is so much increased that these selected wires together with the healds and corresponding warp threads are raised. A modification is described wherein the wires supporting the healds are furnished at their top ends with movable semi-conducting leaves contacting with rising and falling metal bars which may be coated with tungsten, tantalum, or chromium &c., and wherein the return of the healds is effected by a rising and falling beam, the attraction of a magnetic beam being used to tension the shed. In another modification, the wires supporting the healds are caused to be hooked on to the rising and falling metal bars, so that after the coupling has been effected, the supply of current may be cut off. In this case the pattern card may run at constant speed and the wires contacting therewith have a circular movement. A cover of cellophane may be used to protect the apparatus, dry and dust free air being blown in. The cards may be similarly protected. Particles of dust settling on the lifting members may be removed by means of pieces of velvet on the heald supporting members. The semi-conducting members mav be made from resin mixed with finely divided iron or aluminium &c., or may consist of a material such as aluminium which automatically coats itself with a semi-conducting layer of an oxygen compound. Means are described for working with pattern cards punched solely for selecting the pattern and not the binding.

Patent GB-785012-A (GB)
Title: New n-acylated hydroxy prolines and their use in obtaining d-hydroxyproline and l-hydroxyproline
Filed: 1955-03-08
Abstract: The invention comprises N - 3,5 - dinitro benzoylated DL-, D- and L-hydroxy prolines and salts of the acylated D- and L-hydroxy prolines with, as resolution agent, D-(-) and L-(+)-threo-1-p-nitrophenyl-2-amino propane-1,3-diol respectively and their use in the formation of D- and L-hydroxy proline free from one another.  The dinitrobenzoylated DL-hydroxy proline may be prepared by direct acylation or by reacting 3,5-dinitrobenzoyl chloride with an ester or other like functional derivative of hydroxy proline followed by regeneration of the acylated amino acid.  The separate acylated D-and L-hydroxy prolines are produced from the acylated DL derivatives by reaction with the D- or L-form of the resolution agent in an inert solvent in which only one of the two acylated hydroxy proline enantiomorphs gives a salt with the resolution agent which is sparingly soluble in the solvent, separating the salts of the two enantiomorphs by means of their differing solubility and liberating the N-3,5-dinitro-benzoyl-D- and L-hydroxyprolines from their separated salts by treatment with a base followed by acidification. The difitrobenzoyl D-and L-hydroxy prolines are then saponified separately to give the D- and L-hydroxyprolines. Suitable solvents are water, aqueous dioxane, alcohol or other water-miscible organic solvent.  Under these conditions the D- and L-forms of the resolution agent give insoluble salts with the D- and L-forms respectively of the acylated hydroxy prolines; the corresponding D-L- and LD-salts remain in solution.  In examples: (1) DL-hydroxy proline is acylated with 3,5-dinitrobenzyl chloride, in aqueous NaOH; (2) the L-form of the resolution agent is added to N-3,5-dinitrobenzoyl-D,L-hydroxy proline dissolved in aqueous dioxane with stirring at 25 DEG  C.; the resulting precipitated resolution salt of the acylated L-hydroxy proline is removed, treated with aqueous NaOH, the liberated resolution agent is removed and the residual aqueous solution is acidified and worked up to recover the resolved acylated L-hydroxy proline which is hydrolysed to L-hydroxy proline with aqueous HCl; the aqueous dioxane solution, after removal of the precipitated resolution salt, is evaporated to dryness, dissolved in aqueous NaOH, liberated resolution agent removed and the remaining solution is acidified and worked up to recover resolved acylated D-hydroxy proline which on hydrolysis as above yields D-hydroxy proline; (3) the crude acylated D-hydroxy proline obtained in (2) is treated with the D-form of the resolution in the manner described in (2) whereby the resolution salt of the acylated D-hydroxy proline is recovered and is converted as above to the resolved acylated D-hydroxy proline and then to D-hydroxy proline in purer form.  Specification 785,013 is referred to.
Patent GB-1173337-A (GB)
Title: Improvements in or relating to valve devices
IPC: F15B11/08
Filed: 1967-02-14
Abstract: 1,173,337. Valves. ROBERTBOSCHG.m.b.H. 14 Feb., 1967 [15 Feb., 1966], No. 6954/67. Heading F2V. A valve 1, for controlling the state of a power cylinder (59, Fig. 2, not shown), connected to the valve at 18<1>, comprises a main valve 3 having a pressure connection 27 and an exhaust connection 28, and a subsidiary valve arrangement 5 having a landed piston 40, 41, a throttle valve 46 and a check valve 47. Pressure applied to the connection 27 causes, by virtue of the different surface areas of pistons 22 and 24, the piston 22 to seat at 21 thereby bringing the cylinder into communication with exhaust 28. To reverse this connection, so as to actuate the cylinder, a secondary pressure is applied to the duct 55 which pressure is transferred, via passages 54, 36, 49, 50 and 51 to chamber 35 and also, via passages 54, 36, 48, throttle 46 and passage 52, to a chamber 53. Upon a certain elapse of time, as determined by the size of chamber 53 and the force of a spring 42, the pressure acting on the left hand side of piston 41 becomes sufficient to overcome the force of spring 42 and the pressure within chamber 35 and so the piston 40, 41 moves to the right thereby applying the pressure at 55, via passages 54, 36, 49, 50, 51, 32 and 26, to a chamber 7. This pressure causes piston 22 to seat at 21 so bringing port 27 into communication with the power cylinder. Upon a reduction in the signal applied to duct 55 the pressure in chamber 53 is relieved via check valve 47, piston 40, 41 returns to position shown, piston 22 returns to its seating 21 and chamber 7 is exhausted, via passages 26, 32, 33, to atmosphere. In two further embodiments (indicated diagramatically in Figs. 3 and 4, not shown), the inlet pressure is applied to connection 28 and exhaust to connection 27, and the pressure signals applied at 55 and 18<1> are derived from the same source.

Abstract: Diels-Alder adducts of trivinylcyclohexane and cyclopentadiene are made by reacting trivinylcyclohexane obtained from cyclododecatriene by isomerization, with dicyclopentadiene, in an autoclave, at 180 DEG C. for six hours, and processing the products by vacuum distillation. The products are 1,2-divinyl-4-(norbornene - 5 - yl) - cyclohexane, 7 - (31,41 - divinylcyclohexyl) - 1,4,5,8 - bis - endomethylene-1,4,4a,5,6,7,8,8a - octahydronaphthalene, and 5 - (3,4 - divinyl - cyclohexyl) - bicyclo[2,2,1]-heptene-(2).ALSO:Copolymers of ethylene and/or a higher alpha olefine with a minor amount of a Diels-Alder adduct of a trivinylcyclohexane and cyclopentadiene are made by effecting the copolymerization of the monomers in the presence of an organometallic low-pressure-type polymerization catalyst, in particular a Ziegler-Natta-type catalyst.  The Diels-Alder adducts are obtained by heating at 180 DEG  C. in an autocalve cyclopentadiene and trivinylcyclohexane obtained by isomerizing cyclododecatriene. The copolymerization may be effected in bulk, but is preferably effected in a hydrocarbon or halogenated hydrocarbon medium, e.g. in a mixture of hexane and isopropylcyclohexane. The two component catalysts may be modified by a third component, e.g. an ether, thioether, amine, or phosphine. The polymerization may be continous.  The exemplified catalyst is vanadium oxychloride and ethyl aluminium sesquichloride dissolved in hexane and supplied at such a rate that the concentration of the vanadium compound is 1 millimole per litre of hexane, and the concentration of the aluminium compound is 12 millimoles per litre of hexane. The exemplified copolymers are ethylene, propylene and 1,2-divinyl-4-(norbornene-5-yl)-cyclohexane, or 7 - (31,41 - divinylcyclohexyl)-1,4,5,8 - bis - endomethylene - 1,4,4a,5,6,7,8,8a-octahydronaphthalene, or 5-(3,4-divinyl-cyclohexyl) -bicyclo-[2,2,1]-heptene-(2).

Title: Improvements in or relating to electrical members provided with organopolysiloxane insulation
IPC: H01F41/00
Filed: 1957-03-05
Abstract: 835,139. Transformers. WESTINGHOUSE ELECTRIC CORPORATION. March 5, 1957 [March 14, 1956], No. 7266/57. Drawings to Specification. Class 38 (2). The invention is identical with that of Specification 693,819 inasmuch that an electrical member, such as a transformer, is sealed by filling irregularities with a pasty mass which is hardened to a porous solid body, it is then coated with a resinous material through which spaces are left and finally impregnated with a polymerizable liquid resin, but differs therefrom in that different synthetic resins are used. Thus, after a primer coating of an organic titanate or silicate has been applied to the exterior surface of any metal parts, the entire outer surface of the transformer is encapsulated with a pasty organopolysiloxane composition which is then polymerized to an elastomer; an opening is then made through the elastomeric cover and the interior is vacuum impregnated with a polymerizable siloxane or mixture thereof with one or more other siloxanes, the polymerizable siloxane having an average of at least 2 silicon-bonded vinyl radicals per silicon atom, and the impregnant is subsequently polymerized. The polymerizable siloxanes and mixtures thereof are described and claimed in Specification 832,966.
