Title: Improvements in net making machines
IPC: D04G1/00
Filed: 1933-05-02
Abstract: 419,066. Net-making. OKUMA, Y., 12, San - Chome, Fujitsuka - Cho, Higashi - Ku, Nagoya-Shi, Aichi-Ken, Japan. May 2, 1933, No. 12780. [Class 74 (i).] Relates to a machine for making knotless netting from strands issuing from groups of two or more bobbin-spindles 26 and twined together. The twines are caused to penetrate other similarly formed twines by progressing the groups backwards and forwards throughout a series of twisting and crossing raceways 3, 4 arranged alternately in parallel rows. The rows run transversely across the bed-plate and are joined at the ends by transfer raceways of somewhat larger size. The twines are positively disposed in correct relation to each other by means of a series of stepped guide slots into which the appropriate twines are gathered. A zig-zag groove extends from end to end of an arcuate bed-plate 33. Two series of notched plates 35, 40 arranged above the bed-plate 33 are movable in opposite directions. The plates 35, 40 are operated by slide bars 44<11>, 44<111> respectively mounted in the frame 32. Two other plates similarly operated are located at an angle to the plates 35, 40. The slides are reciprocated by grooved cams and linkwork. In extreme positions the notched edges 36 of the plates form a series of small holes which position the twines when crossings are effected, while pivoted horns 51, operated by inclines 49 formed in the plates 40, hold the twines temporarily after the crossings have been made. The net is guided by plates 50 to take-up combs 58, 59 and tensioning members 62. Transfer of the spindles from the races 3 to 4 and back is effected by switches under pattern control. As the net advances the combs rise with it until withdrawn by an arm 56 operated by a cam. The members 62 for tensioning the selvage meshes move with the combs and are operated by inclines 67 on levers 46. The spindles are moved along by overlapping notched carrier discs 6 driven by gearing 74, 75. Switches 10, Fig. 6, pivoted at 9 and operated by slides &c. 16 .... 21 determine the movement of the individual spindles under control of a pattern roller which acts upon feelers 23. When the switches are moved the corresponding spindles cease twisting around in pairs and form the crossings which join the twines together. Fig. 20 and 23 show typical crossings.

Title: Improvements in or relating to heat-transfers
IPC: B44C1/175
Filed: 1950-05-23
Abstract: In a heat-transfer material comprising a temporary support and a layer or design capable of being transferred from the temporary support to a permanent support by the application of heat and pressure, the transferable layer or design contains a blend of resins, the resin content being wholly thermosetting resins and consisting of 50-95 per cent by weight of a melamine-aldehyde resin and 50-5 per cent by weight of an alkyd resin, both resins being in an organic solvent-soluble state but capable of being converted to an insoluble and infusible form by the application of heat and pressure. In making the material, the resins are preferably dissolved in appropriate solvents, e.g. butanol for the melamine resin and xylol for the alkyd, and the resulting solutions mixed together.  Pigments or dyestuffs which are to be added are included in either solution or the mixed solution; the resulting composition is then applied by known methods to the temporary support, e.g. paper.  A curing catalyst may be added to the composition but is preferably applied to the transfer material immediately before or during the transfer operation. Catalysts specified are ammonia, zinc and aluminium sulphates, sodium bisulphate, ammonium chloride; formic, acetic, oxalic and benzoic acids, ethylhydrogen phosphate, dioctyl succinate and trimethylamine hydrochloride.  In examples: (1) a butanol solution of a butylated melamine-formaldehyde resin is mixed with an alkyd in xylol and an aniline pigment, and (2) with titania; (3) the aniline pigment is replaced by titania and benzyl alcohol added. The transference of the layer or design may be effected in the usual way but preferably by applying heat through the medium of a pad moistened with a solution of the catalyst to the reverse side of the fabric and placing the transfer so that the transferable layer is directed towards the source of heat.  Specification 641,412 is referred to.

Abstract: 547,137. Carburetters ; regulating ; lubricating. SCINTILLA, Ltd. Oct. 7, 1941, No. 12945. Convention date, Oct. 7, 1940. [Classes 7 (ii), 7 (iii) and 7 (vi)] An engine working with a carburetter is converted into one operating with a fuelinjection pump by coupling this pump to an existing auxiliary shaft of the engine, replacing the carburetter by an intake system including a nozzle supplied by the injection pump, and by controlling the quantity of fuel supplied by the pump automatically in accordance with the suction in the intake, the mixture being controlled by a throttle. Fig. 1 shows an engine 1 in which the carburetter has been removed from the intake manifold 4 and replaced by piping 8, 9, 10 including a fuel nozzle 13, Fig. 2, connected by a pipe 14 to the injection pump 46, which is coupled at 33, Fig. 3, to the shaft of the dynamo 24. The fuel is injected into a conical chamber 8 supplied tangentially with air by the pipe 10 and a filter 7, a throttle 21 being fitted in the section 9 and operated by the usual control. The shaft 30 coupled to the dynamo drives a swash plate 39 operating several fuel-injection pumps 43 and a lubricating pump 44. The injection-pump pistons 43 are rotated to control the fuel supply by means of gearing 54, 56, shaft 53, and.arm 78 connected to a diaphragm 80 subjected by a pipe 83 to the suction between the throttle and the engine. The outlet chambers 62 of the injection pumps are connected together by passages 63, and one of them is connected to the supply pipe 14. The lubricating-pump 44 draws oil through a passage 68 from the bottom 29 of the pump casing, and delivers it through passages 72, 73, 74 to the injection pump pistons. A byepass 77 returning oil to the sump 29 is throttled at 76 so as to cause a pressure in the oil supply to the passages 74 which is always greater than the fuel pressure in the injection-pump chambers 60. A Bowden wire control of the lever 78 may be provided for obtaining an increased supply of fuel for starting.

Filed: 1972-03-20
Abstract: 1391725 Modifying cellulose fibres; Absorbent products KIMBERLY-CLARK CORP 20 March 1972 13005/72 Headings D2B and D2W A method for producing modified cellulose fibres of improved absorbency comprises saturating cellulose pulp fibres with an aqueous phosphorylating solution; heating the saturated pulp to an elevated temperature to obtain phosphorylated cellulose fibres; washing the fibres with water to free them from reactant; converting the fibres to salt form with an alkali while dispersed in water; and drying the treated fibres in a manner which avoids interfibre bonding. Phosphorylation may be carried out using a solution of urea and phosphoric acid, phosphorous oxychloride alone or with pyridine, phosphoric acid, or dioxane, or an alkali metal salt of phosphoric acid. The phosphorylated fibres may be treated with an acid to convert them to an acid form prior to conversion to the salt form. The treated fibres may be dried using either solvent drying or freeze drying techniques. If ordinary evaporative drying techniques are used, the resulting fibres do not show improved absorbency, although they may be used as supplementary bonding agents in paper. The modified cellulose fibres of the invention may be used alone or blended with other fibres e.g. cotton, rayon, wood pulp in the manufacture of absorbent products.
