Filed: 1966-02-09
Abstract: 1,130,395. Adhesive tapes. T. J. SMITH & NEPHEW Ltd. 2 Feb., 1967 [9 Feb., 1966], No. 5581/66. Heading B2E. An adhesive tape has a backing made from either (a) a thermoplastic sheet material having a regularly spaced relief or recessed pattern on at least one surface, the sheet material being capable of forming a non woven net upon stretching or stressing biaxially; or (b) a thermoplastic sheet material as in (a) that has been stretched uniaxially or biaxially. The thermoplastic material may be polymers or copolymers of olefins particularly ethylene. The adhesive may be solvent, heat, or pressure sensitive and may be of acrylic resin or rubber based e.g. of pale crepe rubber and poly-betapinene resin. Rubber-based adhesive may require the use of a primer coat of, for example, acrylic-rubber emulsion. High density polyethylene backing may be surface treated e.g. by corona discharge, prior to coating with adhesive. The adhesive may be applied to one or both surfaces of the backing by immersion or roller techniques. The tape may be produced 'by (i) applying the adhesive to the unstretched thermoplastic sheet material having a regularly spaced relief or recessed pattern on at least one surface; (2) stretching the adhesive coated unstretched material in one or two directions at right angles; or (3) applying the adhesive to the thermoplastic sheet material which has been stretched in one or two directions. The stretching in two directions may be done in two stages or simultaneously. Where necessary, the openings in the net may be blown free of adhesive, after application of the adhesive to the stretched material, by an air blow. Tapes having adhesive on one surface may be coated on the other surface with a release coating. Tapes coated with adhesive on both surfaces are provided with a releasable liner to permit winding. The tapes may be applied to window glass, or, if coated on both surfaces, may be used to join two or more porous sheets to form a laminate e.g. in clothing.

Title: Felt for paper-making and the like
Inventor: KINOSHITA MICHISUKE
IPC: D04H13/00
Filed: 1968-02-06
Abstract: 1,206,010. Paper-maker's felt. M. KINOSHITA and T. IIZUKA. 6 Feb., 1968 [5 June, 1967], No. 5785/68. Heading D1R. A felt for paper machines comprises a foraminous meshwork backing having an open space ratio (as defined) in the range 10-50% and a mat of non-woven fibres having tufts extending through the meshes of said backing to secure said mat to said backing and being substantially confined to the meshes, the mat being consolidated into a felt. The open space ratio P(%) is defined as:- where a=(diameter of warp in mm) x (number of warps per 50 mm) and b=(diameter of weft in mm) x (number of wefts per 50 mm). The process for producing such a felt comprises forming a non-woven mat containing shrinkable and/or fullable fibres over one or both faces of a foraminous meshwork backing having an open space ratio as above, needling the mat to the backing so that tufts of the mat are disposed in the meshes of the backing, the shrinkable and/or fullable fibres being shrunk and/or filled before the mat is laid on the backing and the distance between the warps and the wefts, whichever is the smaller, being in the range 0.2 to 4 times the diameter of the felting needle. The mat may consist of synthetic, natural or regenerated fibres or mixtures thereof, and the backing may consist of a meshwork of synthetic and/or regenerated fibres or a meshwork of metal wires. The backing or the mat may be impregnated with binding agents e.g. synthetic rubber latices or polyurethane, polyamide, polyvinyl and epoxy resins. In a preferred embodiment of the process, the mat is partially shrunk and/or fulled before being laid upon the backing, and is thereafter fully shrunk and/or fulled. The shrinking ' may be effected by heat and may take the form of a crimping of the fibres.

Title: Improvements in or relating to electrical positional control systems
IPC: G05D3/14
Filed: 1946-02-25
Abstract: 625,567. Electric control systems. SPERRY GYROSCOPE CO., Inc. Feb. 25, 1946, No. 5835. Convention date, June 20, 1942. [Class 40 (i)] In a positional control system, coarse and fine control signals are developed, and the first time derivative of the coarse signal is added to the coarse signal before it reaches the common channel through which both coarse and fine signals act. The invention is described with reference to a gun control system in which signals from coarse and fine receivers 35 and 17 are applied to balanced demodulation rectifier systems 45, 46 and 79, 80, so that D.C. voltages corresponding in magnitude and sign to the magnitude and relative phase of the error voltages are obtained from filters 55 and 85. The " fine " D.C. voltage is applied through a differentiating network to amplifier 60, together with a fraction of the original fine signal from potentiometer 40, and with the " coarse " D.C. voltage which is applied through a network 88 which gives an output proportional to the original signal plus its differential. Two further feed-back voltages are applied to the amplifier (see below) which is A.C. operated and gives an A.C. output corresponding in phase to the sign of any D.C. input or to the relative phase of any A.C. input, and proportional in magnitude to the magnitude of any such voltages. This output voltage is applied to motor 107 which controls the output of continuously driven pump 116 to hydraulic servo motor 119, driving gun 20 and Selsyn rotors 18 and 37, by means of rod 114 coupled to eccentric 112. A feedback voltage proportional to displacement of motor 107 is obtained by integrating the output of generator 125 coupled to motor 107 in network 126 and is applied to the amplifier input together with a signal proportional to the differential of the pressure drop across motor 119 obtained by means of device 140. Normally the fine error signal predominates, but if the error exceeds a predetermined amount the fine signal circuits are shorted out by contacts 30, 32, 33, this being effected by mounting contact 30 on the movable stator of Selsyn 27, connected to the coarse lines, the mains energized rotor being coupled to the gunpositioning mechanism so that the stator moves relative to its surroundings in proportion to the error. Fig. 2 shows an embodiment of device 140 in which pistons 141 and 142, acted on by the input and output pressure of the motor, rock member 153 which moves double cylinder 157 causing member 167 to be displaced against the action of springs 172, 172<SP>1</SP> until sufficient fluid from space 163 has leaked past valve 177 into space 160 or vice versa to enable member 167 to move back to its datum position. The movement of member 167 causing pick-off 168 to produce the desired signal. In another arrangement pistons 141 and 142 squash two carbon piles in a bridge circuit, differentiation of the out-of-balance voltage being effected electrically, Figs. 3 an 4 (not shown). Reference has been directed by the Comptroller to Specification 592,208.

Filed: 1938-02-25
Abstract: 512,038. Synthetic resins. NEUSS, 0. Feb. 25, 1938, No. 6076. [Class 2 (iii)] Protein-containing plastic masses are produced by allowing urea compounds and formaldehvde to react for several hours in ammoniacal solution which is just alkaline to litmus, without application of heat, acidifying the reaction mass till it is just acid to litmus, adding to the protein material, and drying and pressing the resulting condensation mixture at a temperature above 100‹ C. The protein material may be horn meal. In place of acidification, bleached horn meal with a content of sulphur dioxide may be used. In an example, 60 gr. of urea are dissolved in 120 gr. of 30 per cent. aqueous formaldehyde solution. This solution in neutralized with ammonia till just alkaline to litmus. The solution is allowed to stand for 3 hours. 150 gr. of the solution is then mixed with 50 gr. of horn meal which has been treated with sulphurous acid and the paste dried and hot pressed at 130‹-C. Thiourea may be used. Casein may be used instead of horn meal. The horn meal or other protein may be swelled prior to the reaction.
Patent GB-568394-A (GB)
Title: Improvements in the manufacture of artificial films, filaments and the like
IPC: D01F2/08
Filed: 1943-04-21
Abstract: Artificial filaments, films, etc. are produced by extruding a solution of viscose into a precipitating medium containing a condensation product of an aliphatic alcohol an anhydroderivative thereof or a sugar with ethylene oxide.  The product has at least nine ethylene oxide units per molecule and is free from groups more hydrophobic than a hydrocarbon radical of 5 carbon atoms.  Suitable alcohols from which the condensation product is derived include methyl, ethyl, propyl, and isopropyl alcohols, polyhydric alcohols such as glycols, glycerol, and erythritol, pentahydric alcohols, hexahydric alcohols such as mannitol, sorbitol, and dulcitol, heptahydric alcohols, and anhydroderivatives such as glycide, mannitan, sorbitan, mannide and sorbide.  Sugars such as glucose or sucrose may also be included.  Substituted alcohols may be used provided any substituent does not impart to the condensation product a group more hydrophobic than a hydrocarbon radical of 5 carbon atoms. The invention ensures uniformity in product and reduces any tendency of the filaments to break during spinning, particularly when high spinning speeds are employed and when the spinning solution contains a high proportion of combined carbon disulphide. Numerous examples are given in which the spinning bath contains condensation products of ethylene oxide with mannitol, glycerol, glucose, and sulrose along with sulphuric acid, sodium sulphate, zinc sulphate and glucose.  The number of ethylene oxide units per molecule of condensation product may be more than 50 and in one example it is 300.
