Patent GB-381661-A (GB)
Title: Improved manufacture of sterilised catgut
IPC: A61L17/08
Filed: 1931-08-17
Abstract: A process of sterilizing catgut is characterized in that the insufficiently sterilized, undried intestine sections are suspended individually each in two loops so that they hang freely in a covered trough, which is filled with a sterilizing solution, for example, of iodine, before or after placing the threads in position so that the threads and loops are submerged.  Hemp loops may be used, but rustless steel is preferred.  Each loop is pushed over one of two supporting rods of rustless material positioned in the trough.  After sterilization, the solution is removed and may be replaced by other solutions for purposes of removing excess of sterilizing agent, or of tanning the thread or of charging it with antiseptics.  After the last solution has been discharged, the threads are allowed to drain and then removed for drying.  A statement of prior art refers to the incomplete sterilization of the threads by suspending them in bundles in the solution, or by placing a bundle horizontally in the solution, and by stirring the same.

Title: An improved games racquet
IPC: A63B51/00
Filed: 1926-09-25
Abstract: 287,583. Claremont, C. A. Sept. 25, 1926. Rackets.-In a games racket the rim is pliable in the plane of the racket to afford wholly or in part the required resiliency and the stringing is arranged so as not to oppose the yielding of the rim. The rim may be made of steel, wood or other suitable material capable of yielding to the required extent and the stringing may consist of steel wires or other comparatively non-stretchable material, or gut stringing may be used. In determining the position of the strings a drawing of two positions b and c of the rim, viz. the normal and a distorted position are first ascertained by applying a distorting force to the rim, and the position of each string is inserted by the use of dividers so that its two extremities either move closer together or remain the same distance apart when the frame is distorted. One or more strings may be introduced so as to oppose the free distortion of the rim.

Abstract: 480,861. Braid. PRICE, W. H. Aug. 28, 1936, No. 23670. Convention date, March 9, 1936. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 1, 1937.] Addition to 477,473. [Class 74 (i)] The invention described in the parent Specification is improved or modified in that the fancy threads 10 are caused to stand up from the plane or surface of the fabric on either side. This is done by the use of empty bobbins, which guide the fancy threads on the reverse side of the fabric, as required. The ground work may be made dense enough at these places to conceal the fancy threads 10, when viewed from the opposite face. The threads 10 may be tied in at intervals and may serve to outline a pattern. According to the Specification as open to inspection under Sect. 91 the threads 10 may be elastic. This subject-matter does not appear in the Specification as accepted.

Title: New and improved organo-silicon condensation products
Inventor: JACK JAMES
IPC: C07F7/18
Filed: 1957-07-26
Abstract: An organosilicon condensation product is obtained by reacting together one or more aromatic di-hydroxy compounds having at least 2 aromatic nuclei, two of which are linked together either directly or through a C atom, the 2 linked nuclei each having a OH group in a position ortho to the linkage, and one or more silanes of the formula Rn SiX4-n, where R is hydrogen or a monovalent hydrocarbon radical, X is a halogen atom or a lower alkoxy radical and n is 1, 2 or 3. Reactants specified are (a) aromatic dihydroxy compounds - 0,01 - dihydroxydiphenyl, 0.01-dihydroxydiphenyl methane, 5.51-dichloro2.21-dihydroxydiphenyl methane, di-b -naphthal, bis (2-hydroxy-1-naphthyl)- methane, and bis (2-hydroxy-3, 5-dimethylphenyl)-methane and (b) silanes-trimethylchloro-, methyltrichloro-, dimethyldiethoxy-, methytriethoxy-, phenyltrichlorodiphenyldichloro-, diphenyldi-ethoxy-, naphthyltrichloro- and vinyltrichloro-silanes and silicochloroform. The reaction may be effected in the presence or absence of a solvent, e.g. benzene, xylene or toluene. When using a halogenosilane, a hydrogen halide accepted may be added or the hydrogen halide may be removed as formed by the passage of a stream of inert gas, e.g. nitrogen.  The reaction is normally effected at elevated temperatures, e.g. by heating under reflux.  In typical examples (1) a mixture of CH3 SiCl3, 2. 21 dihydroxydiphenyl, pyridine and benzene was refluxed for 2 hours, cooled and the precipitated pydrine hydrochloride filtered off, to give a resinous product; (2) the reaction of CH3Si(OC2H5)3 and 2.21-dihydroxydiphenyl gave 2.21-di[methyl(2.21-dioxydiphenylene)siloxy] diphenyl and a resinous product identical with that of (1); (3) the reaction of C6H5SiCl3 and bis-(2-hydroxy-naphthyl) methane gave a dark coloured thermoplastic resin; (7) the reaction of (CH3)2Si(OC2H5)2 with 2.21-dihydroxydiphenyl gave 2.21-dioxyphenylene dimethylsilane.  (12) the reaction of silicochloroform with 2.21-dihydroxydiphenyl gave 2.21-(dioxydiphenylene) chlorosilane).  Uses: as heat exchange media, for waterproofing masonry and as resin intermediates.

Patent GB-937422-A (GB)
Title: An improved method of and apparatus for producing flattened tubular film from thermoplastic materials
Inventor: GERBER KENNETH GEORGE
IPC: B29C48/10
Filed: 1959-07-14
Abstract: Flattened tubular film is produced by extruding a hot synthetic organic normally solid polymeric thermoplastic material, such as polypropylene through a die 2 (Fig. 1) to form a tube 3 which is drawn past a cooling can 4 by two endless moving belts 5 which are parallel to and engage the tube.  There may be more than two such belts uniformly spaced around the tube.  The belts are made of resilient material and shaped to conform to the periphery of the tube.  Instead of belts there may be provided rows of wheels the peripheries of which engage and are shaped to conform to the periphery of the tube.  After the tube leaves the <PICT:0937422/IV(a)/1> belts 5 it is drawn by nip rolls 7 through a heater 6 by means of which the tube is heated to temperature which permits orientation of the molecules of the tube material and lateral and longitudinal stretching of the tube.  Gas, preferably air, at superatmospheric pressure is introduced into the tube 3 through a pipe 8 which extends through the die 2, cooling can 4 and a sealing member 9 provided with two frustoconical tube-engaging elements 11 which are spaced apart axially and engage the interior of the tube 3 and thus provide a seal such that while the tube zone 12 and the bubble 10 contain gas at super-atmospheric pressure the zone 13 of the tube 3 remains at atmospheric pressure and distortion of the tube in the region of the die 2 is thus prevented.  The peripheral speed of the nip rolls 7 is greater than the linear speed of the belts 5 so that the film is stretched longitudinally as well as being stretched laterally by the bubble 10.  The process and apparatus of the invention avoids substantial distortion of the tube prior to the formation of the bubble.
