Title: Improvements in corset clasps
IPC: A41F1/04
Filed: 1919-05-20
Abstract: 149,780. Marks, E. C. R., (International Corset Co.). May 20, 1919. Stud-and-slot fastenings.-Relates to a corset clasp of the type comprising a key-hole slot member carried by one of the parts to be joined and formed with rigid inclined surfaces adjacent the slots therein adapted to engage the head of the stud members carried by the other of the parts to be joined. The slotted member is formed on either side of the slot with an integral inclined surface or shoulder rising to substantially its greatest height at the limit of movement of the stud member, so as to support the head of the latter at said highest point for the purpose of securing the corset stays in close unyielding contact. As shown in Figs. 3 and 4, the portion of the slotted member 2 adjacent the narrow end of the keyhole slot 8 is bulged up to form the raised inclined supporting-surfaces 10, which engage the head 5 of the stud 3 when the latter has reached the limit of its movement, thus maintaining the two edges A, B of the corset in close contact. The forward slope 12 facilitates the movement of the stud head into position, and the undersurface of the part 11 is rounded at 14 to disengage readily the stud head when it has been inadvertently positioned in the recess formed by the undersurface of the bulge. In the modification shown in Fig. 7, the bulge is replaced by a pair of parallel flanges 15 formed with supporting edges 17 and front guiding edges 16, and in that shown in Fig. 9 the slotted member is bent to form a ridge 19 providing the raised supporting- surfaces 20.

Title: Improvements in or relating to the manufacture of phenolic resins
Inventor: REDFARN CYRIL AUBREY
IPC: C08G79/04
Filed: 1954-05-01
Abstract: In Example 42 a graphite beaker is made impervious to water by first impregnating it with a solution in methyl ethyl ketone of a resin obtained by polycondensing hydroquinone, phosphorus oxychloride and polyphosphochloronitride (see Group IV (a)), then partially removing the solvent under vacuum, next impregnating the beaker with formalin and finally baking it in an oven at 200 DEG  C. for 20 minutes to effect thermosetting of the resin.ALSO:A heat-resistant resin is made by reacting a polyhydric phenol with boric acid, an inorganic phosphoric acid or a polyfunctional chlorine derivative thereof or phosphorus trichloride to form a polynuclear compound containing unreacted phenolic hydroxy groups and curing this polynuclear compound with an aldehyde or a substance yielding an aldehyde. Specified are: phosphoric acids and chlorine derivatives-ortho-, meta- and poly-phosphoric acids, cyclic metaphosphoric acid, phosphorus pentachloride and phosphorus oxychloride; polyhydric phenols-resorcinol, pyrogallol, hydroquinone, catechol, phloroglucinol, tolu-hydroquinone and diphenylolpropane; aldehydes and substances yielding them-formaldehyde, furfural, hexamethylene tetramine, trioxane, paraformaldehyde, tetra - kis - (hydroxymethyl) phosphonium chloride, tris-(hydroxymethyl) phosphine oxide and partially condensed phenol- or urea-formaldehyde resins.  When using phosphorus oxychloride or pentachloride, reaction may be effected in presence of pyridine to absorb hydrogen chloride. Polyphosphochloronitride, monohydric phenols or partial esters of monohydric phenols with phosphoric or boric acids may be included in the reaction mixture.  In examples: (17) a coating composition comprises a mixture of a hydroquinone-phosphorus oxychloride resin and a phenol-formaldehyde resin dissolved in ethyl alcohol.  (24) A moulding powder comprises a resorcinol-phosphorus oxychloride resin, asbestos powder or china clay and hexa.  (25 A coating composition comprises a hydroquine-phenol-boric acid resin and a urea-formaldehyde resin dissolved in ethyl alcohol.  (28) A hydroquinone-phosphosphorus oxychloride resin is heated with aluminium octoate and the product cured with hexa.  (30) A moulding composition comprises a hydroquinone-phenol-boric acid resin, graphite and hexa.  (42) A graphite beaker is impregnated with a solution in methyl ethyl ketone of a hydroquinone-phosphorus oxychloride - polyphosphochloronitride resin and is then impregnated with formalin and baked in an oven to cure the resin (see Groups III and VIII).

Title: Improvements in and relating to the measurement of linear dimensions
Inventor: EVANS JAMES CHARLES
IPC: G01B13/08
Filed: 1956-04-25
Abstract: 819,918. Rolling. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 23, 1957 [April 25, 1956], No. 12725/56. Class 83 (4). [Also in Groups XIX and XXIX] Apparatus for measuring or controlling the thickness of thin sheet material 12 whilst it is in motion, by fluid gauging, comprises a nozzle 21 through which the fluid is discharged carried by a rigid support 17 which takes a direct bearing on the periphery of a roller 14 over which the material 12 passes, the nozzle 21 being arranged in substantially the same axial plane as the region of contact between the support 17 and the roller 14, this region being clear of the path of the sheet material. The material 12, e.g. cellulose acetate film of metal foil, passes under rollers 15 and over a measuring roller 14. The ends of the roller 14 carry a Y-shaped support 17 by means of pads 31 of a material having a low coefficient of friction, the support 17 being spaced a suitable distance from the roller 14 by packing pieces 33 which are slotted and so may be withdrawn endwise. The support 17 carries a plurality of nozzles 21 between its ends, these being adjustable towards or away from the roller 14, by means of a nut 34, and each having an adjustable leakage valve (not shown). Flexible connections 36 lead to one or more indicating or recording instruments. These may be pressure-sensitive capsules, or vertical tubes containing liquid, or there may be a valve (see Group XXIX) which can connect each nozzle as desired to a single recording instrument. Alternatively, the average of the pressures in the nozzles 21 may be indicated, e.g. by connecting a stack of capsules together. A pneumatic amplifier, for controlling the spacing of the rollers in a rolling mill, may also be provided. To set up the apparatus, datum packing pieces 33 are used, with no material on the rollers and the nozzles adjusted by the nuts 34 until they all show the same reading. The pieces 33 are then replaced by others, which are thicker than the datum pieces by the nominal thickness of the material to be measured. By this means and the use of the support 17 resting on the roller 14, errors due to eccentricity and lack of circularity of the roller 14 are substantially eliminated. The Y-shaped support 17 may be replaced by a support having a single contact surface.

Title: Improvements in or relating to artificial nitrogenous textile fibres
IPC: D01F4/00
Filed: 1938-05-02
Abstract: 507,114. Casein artificial fibres. DONAGEMMA, G., DONAGEMMA, P., and SNIA-VISCISA SOC. NAZIONALE INDUSTRIA APPLICAZIONI VISCOSA. May 2, 1938, No. 13103. Convention date, May 3, 1937. [Class 2 (ii)] Artificial textile fibres are produced by spinning a caustic soda solution of casein containing a borate of soda such as borax, or a phenol, or, a homologue of phenol, or creosote, or a mixture of any of these substances. The presence of these substances in the casein spinning solution renders a separate treatment of the coagulated casein fibres with a fixing agent such as formaldehyde unnecessary. Viscose, cellulose acetate or cuprammonium cellulose may be incorporated in the casein spinning solution, for example in such proportion that 100 parts of the mixture of casein solution and cellulosic solution contain 10 to 75 parts of casein solution. In examples, a caustic soda solution of casein containing phenol and/or borax, with or without viscose, is spun into a coagulating bath containing sulphuric acid and zinc sulphate. The Specification as open to inspection under Sect. 91 refers to a process for the production of nitrogenous artificial textile fibres in which nitrogenous raw materials are dissolved in alkalis and are thereupon spun in a coagulating bath characterized in that a fixing agent for the nitrogen content is incorporated in the mass to be spun before spinning. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in or relating to the manufacture of electric battery separators
Inventor: CALLENDER LESLIE HUGH
IPC: H01M50/491
Filed: 1950-05-25
Abstract: 679,514. Batteries. YOUNG ACCUMULATOR CO., Ltd. May 25, 1951 [May 25, 1950], No. 13175/50. Class 53. [Also in Group VIII] An accumulator separator is made by coating a sheet of glass or other fibres with a plastic material in finely divided form and heating the coated sheet to cause the particles of plastic material to coalesce or sinter and become bonded to the fibrous sheet. The fibrous sheet may consist of glass wool loosely woven into a mat or of matted filaments of a plastic material such as polyvinyl chloride, polystyrene or polythene, and the coating may consist of polyvinyl acetate, methyl methacrylate, or other synthetic resin. The fibrous sheet may be stiffened by a binder of synthetic resin which may be applied as a powder or in solution and which is cured simultaneously with the heat treatment of the coated sheet or as a separate prior treatment. In another method of stiffening the sheet it is perforated before the application of the coating so that the latter fills the perforations and forms keys extending through the sheet. In another method the sheet is divided into strips which are spaced apart during the coating operation so that strips of plastic material are formed in the body of the finished separator. In order to increase the porosity of the separator a gas-forming substance may be incorporated in the plastic material with which the fibrous sheet is coated. Sodium carbonate, lead carbonate or diazoamino-benzene may be used for this purpose. The Figure shows an apparatus for making the separators. A glass fibre sheet 1 is fed from a roll 2 and passes between rollers 3 one of which dips into a water trough 4. The damped sheet passes on to a conveyer belt 6 and under a heated roller 7 which dries and smooths the sheet which then passes below a vibrating sieve 9 supplied from above with powdered polyvinyl chloride. A blade 10 ensures a uniform thickness of the polyvinyl chloride on the sheet which then traverses an oven 11 in which the particles of the chloride become sintered. The sheet is cooled by an air blast at 13 and removed from the conveyer by a scraper 14. A guillotine 17 cuts the sheet into the required lengths 19. The sheet may be immersed in a solution of phenol formaldehyde and cured in an oven before or after receiving the coating of plastic material from the sieve 9. Specifications 448,468 and 632,061 are referred to.

Title: Improvements in or relating to arrangements for splicing paper or like webs
Inventor: RALPH FREDERICK WALLACE
IPC: B65H19/18
Filed: 1962-04-05
Abstract: 963,765. Feeding webs. WITTON-JAMES Ltd. June 6, 1963 [April 5, 1962], No. 13181/62. Heading B6B. When a web 9 unwinding from a reel 2 is expiring, the spider 1 is rotated by a motor 8 to bring the replacement reel 3 adjacent the web 9. At the same time a motor 10 under control of a servo-system related to the speed of the printing press and thus to the linear speed of the web 9 is caused to accelerate until the speeds of the reel 3 and web 9 are approximately the same. The spider is stopped with the reel still out of contact with the web by a cam switch in a housing 6. Inactive adhesive is present on the web or the reel 3. The spider is then moved further to bring the reel into contact with the web 9, and any difference in speed is corrected by a monitoring device responsive to the drag between the reel and web. When the speed matches, activating solvent is applied from a spray 13. As the web 9 is displaced by the reel 3, it intercepts the optical axis of photo-electric means 7, controlling the spider movement. After splicing, knives 14 sever the web 9, and the spider is rotated to bring the reel 3 to operative position under cam control.
