Granted: 1983-05-11
Abstract: PCT No. PCT/EP80/00045 Sec. 371 Date Mar. 10, 1981 Sec. 102(e) Date Feb. 27, 1981 PCT Filed Jul. 5, 1980 PCT Pub. No. WO81/00263 PCT Pub. Date Feb. 5, 1981.The present invention concerns a method and an apparatus for producing a draftable staple fibre sliver (12) from a strand (12) of endless filaments, which is united and condensed for further processing. According to the invention the zone of the united and condensed sliver, from which, due to the cutting process, fibre points stick away inclined and pointed towards the front and outside, is inserted into the inside of the sliver. In this manner the detrimental effects, caused by the fibre points sticking out, are eliminated. Particularly the defective points in the end product produced, caused by these fibre points, are eliminated, fly waste generation in the processing room is reduced and, owing to the reduction of the danger of clogging of the fibre sliver guiding funnels, the operational reliability of the subsequent processing machines is improved.

Abstract: Alkali metal or alkaline earth metal peroxides, for example, particularly, calcium peroxide, is produced by recovering a moist peroxide product from an aqueous mixture, formed by reacting hydrogen peroxide and a hydroxide of the alkali metal or alkaline earth metal, and drying the moist product by means of a pneumatic conveyer drier. The peroxide so produced is suitable for granulation. Alternatively, particulate substances, such as seed, are coated with the peroxide by bending with the moist peroxide product and passing the blend through the pneumatic conveyor drier.

Abstract: The sensor for measuring the pressure of a medium comprises a wire (5) the resistance of which varies in accordance with the pressure. The wire (5) is placed within the medium in a coil or pleated form or the like. Preferably a portion (5a) of the wire is protected from the pressure. The protected portion (5a) of the wire and the portion (5b) exposed to the pressure are forming the branches of a bridge circuit. In order to measure the combustion pressure in combustion machines, circuits are located in the chamber (11) of a spark plug or disposed with the electric conductors (21) (44) of an incandescent plug. Combustion pressures may thereby be obtained by controlling and/or adjusting injection and/or ignition systems without further borings. In other embodiments of the sensor high pressure may also be measured, for example the pressure in an injection pump.

Abstract: A key actuated membrane switch comprises a key operated switch actuating member 101 in the form of a key module and a membrane switch panel 111. The switch panel consists essentially of three membranes (112, 113, 114), one on top of the other, sealed together with adhesives. The upper and the bottom membranes (112, 113) are each continuous and each has at least one contact (115) and a respective conductor formed on its interior surface. The middle membrane (114) has at least one aperture (117) which defines a switch cell. The two contacts (115) are coaxially aligned with the aperture so that pressure on the upper membrane (112) along the axis of the aperture, causes the two contacts to come together and make a circuit. The membrane package is mounted, preferebly by an adhesive, on a rigid base 120. Pressure is selectively applied to the upper membrane by means of the key operated switch actuating member (101) via the agency of a cantilevered single-arm spring (104) which acts to apply leverage on the upper membrane (112) when the actuating member (101) is operated. The spring has a first portion which extends from the supported end of the spring in a plane parallel to the plane of the upper membrane to the vertical axis of the said contacts, and a
