Title: Weftless tape
IPC: D04H3/00
Filed: 1960-05-02
Abstract: 923,184. Uniting threads by adhesives. AMERICAN VISCOSE CORPORATION. May 2, 1960 [March 30, 1960], No. 15384/60. Class 74 (2). [Also in Group IX] Weftless tape comprises a plurality of parallel textile strands predominantly composed of continuous and aligned filaments, secured together in side-by-side arrangement by a flexible film-forming plastic, at least every alternate strand containing some surface filaments with portions extending outwardly from the strand surface in overlapping and engaging relationship with an adjoining strand. Suitable continuous filaments are natural silk, glass, artificial cellulosic filaments such as rayon, synthetic resin filaments such as nylon, polyesters, olefins, and acrylic compounds. Suitable film-forming plastics are viscose, water-soluble and alcohol-soluble cellulose ethers, organic solvent soluble cellulose esters and ethers, glue, gelatine, casein, vinyl resins, nylon, polyester and acrylic resins, natural and synthetic rubber latices and solutions. The plastic may contain plasticizers, softeners, dyes and pigments. The strands may be untwisted bundles of continuous filaments or yarns of continuous filaments that have a low or a higher twist. The strands may also be two or more bundles or yarns that have a low or higher twist and which are cabled or plied together to form a cord. Strands with protruding filaments may be made by drawing the strands over a rough or cutting surface stretching them to break surface filaments or subjecting them while untensioned to a stream of air which loosens surface filaments and forms them into loops or whorls. As shown in Fig. 4, a tape comprises a plurality of strands of continuous filaments. Protruding filaments 29, forming part of strands 27 and 28, extend outwardly from these strands so as to envelope adjacent strands and are embedded in plastic 30. In making the tape, a plurality of strands or yarns having the requisite laterally extending filament portions are drawn from a source of supply, arranged in juxtaposed side-by-side relationship, passed through a bath containing a suitable flexible film-forming plastic binder and then through squeeze rolls.

Title: Process for curing epoxy resins
IPC: C08G59/62
Filed: 1957-05-15
Abstract: Epoxy resins having an average number of epoxy groups per molecule of more than 1 are cured by heating with a polyalkyl hydroxyphenyl chroman derivative containing at least 3 phenolic OH groups and having the formula <FORM:0814694/IV (a)/1> in which either X or Y is a group of the formula <FORM:0814694/IV (a)/2> where n is 1 or 0, the other being an alkyl group, in the presence of a catalyst which is a normal curing agent for epoxy resins. The chroman derivative may contain substituents such as alkyl groups.  The specified compound is 2,4,4-trimethyl - 7,21,41 - trihydroxyflavan.  Examples of catalysts are piperidine, triethanolamine, diethylene triamine, m-phenylene diamine, hydrogenated phenylene diamines, carboxylic acids, sulphonic acids and anhydrides.  Generally, from 20 to 150 parts by weight of chroman derivative are used per 100 parts of resin. The catalyst, if an amine, amounts to preferably not more than 1 per cent of the mixture of resin and chroman derivative.  Curing temperatures are usually less than 250 DEG  C.  Chroman derivatives which are immiscible with the epoxy resin at room temperature may be heated with the resin above 120 DEG  C. to form a homogeneous blend which, on cooling to a solid, is still fusible and soluble in the resin solvents.  Final curing may be effected by heating the solid to between 100 DEG  and 200 DEG  C., adding the catalyst and maintaining the heating for some hours.  The epoxy resin used in the examples was the reaction product of bis-phenol and epichlorhydrin, having a molecular weight of 370 and an epoxy equivalency of 1.85.

Filed: 1970-04-01
Abstract: 1307905 Anaesthetic evaporator SACCAB SpA 1 April 1970 [1 April 1969] 15481/70 Heading A5T An evaporator for volatile anaesthetics adapted to cause the surface area of evaporation to vary in inversely to the vapour pressure of the liquid, comprises two coaxial cylinders 2, 3 defining an annular space 6 between them which is sealed at its ends by rings 4, 5, and a base 9, having a domed portion 10 extending into the inner space 8 defined by the inner cylinder 3, the portion 10 having a layer 11 of porous material, e.g. gauze, sintered metal, affording a large surface area. Liquid anaesthetic is introduced through a funnel 16 such that it occupies a part of the space 6 to the line 18 and covers part of the domed base portion 10, flowing into the inner space 8 via a plurality of holes 7. Gas is caused to flow into an axial tube 14 from a deviating valve 13 at the top of the apparatus, which gas absorbs anaesthetic vapour from the surface 11 and flows out as shown, the portion 15, slidably mounted on the tube 14, serving to limit the volume of the evaporation chamber. As evaporation takes place, the liquid cools and cools the air and vapour mixture trapped in the outer space 6 causing a reduction in volume and pressure of the gas and a rise in the liquid to the point 19, a corresponding fall of the liquid in the inner space 8 results in a greater surface of evaporation being available.

Abstract: 727,491. Echo-sounding apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 10, 1953 [June 25, 1952], No. 16024/52. Class 118 (2). [Also in Group XIX] Echo.signals converted into pulsating electric signals are caused to modify the amplitude of continuously-produced oscillations in accordance with the intensity of the received echo signals, the modified oscillations being applied to a stylus which produces on electro-sensitive chemically-prepared paper a mark corresponding in density to the intensity of the signal. The electric signals after passing, if desired, through an adjustable-gain amplifier are applied at the points IN to the circuit shown and pass as negative pulses through a rectifier MRI and filter circuit R3, C2, C3 to reach the first grid G1 of a double triode KA, KB, the second section VIB of which is operating as a tunedanode oscillator with an anode circuit ATC working at the anode voltage of the first section VIA. The negative pulses at the grid GI change this anode voltage and consequently modify the amplitude of the oscillations in the circuit ATC. The said modified oscillations pass through an amplifier G3 to the recording stylus S. The frequency of the said oscillations is materially different from and not harmonically related to the input oscillation frequency. A potentiometer RV5 is so adjusted that, in the absence of input signals, the recorder produces a just-discernable mark and the gain of the initial amplifier (not shown) is set so that the largest signals expected will result in the maximum possible density of mark.

Abstract: 1,100,743. Aircraft instruments; hydrofoils. BOWLES ENGINEERING CORPORATION. 14 April, 1965 [14 April, 1964], No. 16047/65. Headings B7A and B7W. [Also in Division G3] A system for sensing lift forces acting on an aerofoil or a hydrofoil when in motion comprises a pressure-sensitive device within the foil and arranged to produce an output signal which is a function of the difference between the fluid pressures at two ports in the foil adjacent its leading edge, wherein said pressure sensitive device is a pure fluid amplifier having a power nozzle, at least two fluid-output passages for receiving fluid from said power nozzle, and a pair of control nozzles connected respectively to said two ports through separate passages. A foil 10a is formed with ports 12, 13 which connect through passages 22 and 23 provided respectively at their ends with flow restrictors 24, 27 and 26, 28 and intermediate their ends with metering or restricting orifices 19, 21 incorporated in a supply line 16, 17 from a source of pressure fluid 14. The restrictors in the passages 22 and 23 establish a minimum pressure in the passages which is changed by variation of flow over the ports 12, 13 as by variation in the angle of attack of the foil 10. Source 14 delivers pressure fluid to a nozzle 30 which directs it towards output passages 31, 32 and 33, passages 31 and 33 being connected to a lift indicator 35 or other utilization device. Passage 32 connects back to source 14 or spills overboard. Variation in pressure in passages 22 and 23 resulting from variation in angle of attack of the foil deflects the flow from nozzle 30 to influence or unbalance the pressures in passages 31, 33 to operate device 34. The ports 12 and 13 may be located at different distances from the leading edge and in a further embodiment flexible diaphragms are inserted across ports 12 and 13.
