Title: Thread tension control mechanism
IPC: B65H59/10
Filed: 1966-05-03
Abstract: 1,098,215. Thread - tensioning apparatus. THERMIGUIDES S.A. May 3, 1966 [May 14, 1965], No. 19518/66. Heading D1D. Means for controlling the tension in a yarn, comprises a feeler movable when the tension rises against a controlling-force, the movements of the feeler actuating a tensioning-device to keep the tension constant for a given value of the controlling-force. The controlling-force is applied by a pressure-sensitive member subject to the pressure in a pneumatic system in which the pressure is the same throughout and can be adjusted by a device which includes a movable part subject to the pressure and to an adjustable force which determines the pressure in the system. The feeler 8, Fig. 3, is secured to a boss fixed on a spindle 6. Projecting from the boss oppositely to the feeler is a sector-shaped plate on the inner face of which is the movable member 18 which cooperates with two fixed members 16 to form a tensioning-device. The yarn passes to a guide on the end of a feeler between two fixed guide pins, then to a grooved pulley 10 loose on the spindle, through notches in the members 16 and over the end-surface of the member 18. The members 16, 18 are arcuate about the spindle as centre and the member 18 varies in depth along its length, so that it tensions the yarn to a greater or less extent as it moves between the members 16 (Fig. 6, not shown). The controlling-force is applied to the spindle by a cord fixed at one end to a pulley (7) and at the other to a diaphragm 2, Fig. 4. The other side of the diaphragm is subject to the reduced pressure in a pipe C. A series of such pipes C, each controlling a tensioner, is connected by a manifold B to a cylinder A, Fig. 1, a piston in which is loaded by weights. With the piston at the top of its travel, the air in the system is connected to a low-pressure source through a valve 25 which is then closed, so that a reduced pressure is established in the system depending on the loading of the piston which is selected according to the working tension desired. Any movement of one or more of the diaphragms will not affect the pressure in the system, since any change in the volume of air in the system will result in a movement of the piston without any change in the force applied to it. In other forms, (a) the controlling force is applied to the spindle by a cord which passes around a pully attached to the diaphragm and having its ends fixed to two pulleys of different diameters on the spindle, (Fig. 8, not shown) so that changes in the pressure in the system will produce only very small differences in the torque applied to the feeler; (b) the reduced pressure in the system is established by weights attached to a bellows the interior of which is connected to the manifold B and the valve 26 and which has a damping- device; (c) above-atmospheric pressure may be employed instead of reduce pressure in the system B, C.

Abstract: 1402941 Coated galvanised sheet steel: coat ing apparatus ROBERTSON BAUELEMENTE GmbH 25 April 1973 [1 May 1972] 19533/73 Headings B2E and B2L [Also in Division C3] A post-formable protected galvanised steel sheet comprises a galvanised steel core having a wash primer coat applied to at least one surface of the galvanised core and a weather resistant hot-melt alkyd resin coat applied to the wash primer. Preferably a roll 10 of galvanised steel sheet is unwound and cut by a guillotine 11 into sheets 12a which are heated to 60-100‹C, supported and impelled by an uprush of hot gases from burners 20 in a chamber 13. The sheets are coated on both sides with a wash primer in a volatile solvent by rollers 14, the thickness of the coating being governed by doctor rolls 22, 25, Fig 5, Flashing off of solvent is aided by passing the coated sheets through a first drier 15 wherein the sheets are supported, heated to above the solvent flash temperature and impelled by an uprush of warm recycled air which passes through a perforated plate 32 from plenum chamber 31. The primer is reheated to 60- 105‹C in a chamber 16 wherein heat is supplied by combustion gases passing through a perforated base then through a flue 34 to a pump 29 then a pipe 30 to be recycled through chamber 15. The heated sheet is hot-melt coated with the alkyd resin by rollers 17 before being quenched in a water tank at a temperature at least 50‹C below the softening point of the hot-melt coating. The hot melt alkyd may cross-link in air so that after a period of exposure, it becomes non-softenable, and the sheets non-postformable. The primer system preferably, includes polyvinyl butyral, zinc tetroxy chromate, solvents and aqueous phosphoric acid (see Division C3). The primer may include modifying resins such as melamine, phenolic resins, vinyl ethers, phenoxy resin, epoxy resin or alkyd resins. The primer is applied as a dispersion in an organic solvent. The alkyd resin is preferably formed from the esterification of unsaturated aliphatic acids (e.g. tall oil fatty acids, oleic acids, dehydrated castor oil, tung oil, linseed oil), alkyl (meth)- acrylates, dicarboxylic acids such as phthalic aci dor triols such as trimethylol ethane. The resin may also contain waxes, wetting agents, driers (e.g. cobalt naph'thenate), pigments, or inert fillers (e.g. crushed limestone, talc or short asbestos fibres).

Title: Improvements in and relating to methods of utilising rubber waste
IPC: C08L19/00
Filed: 1931-07-07
Abstract: Moulding materials, capable of being softened by heat and possessing good resistance to alkalis particularly ammonia, are made from rubber dust or waste and a resinous aldehyde amine condensation product which has a softening point within the range of temperature at which the rubber is in a soft or plastic state. The softening point of the resin is chosen within the above limits having regard to the amount of heat it is proposed to use in moulding.  The sulphur contained in the rubber is stated to produce a certain degree of vulcanization in the resin.  In an example 80 parts of ebonite dust is mixed with 20 parts of resin having a softening point at about 100 DEG  C. when in the presence of a suitable amount of solvent.  After mixing, the solvent is removed in a vacuum, and the material is pressed in matrices at 150 DEG  C. at 150-200 kilograms per square centimetre for 40-60 seconds per millimetre of thickness of the article.

Abstract: 1,009,355. Semi-conductor devices. WESTERN ELECTRIC CO. Inc. May 24, 1962 [June 8, 1961], No. 19959/62. Drawings to Specification. Heading H1K. An alloyed contact region is produced in a semi-conductor body by vapour depositing on the body a charge comprising a metal and the same semi-conductor material and heating the body to a temperature below its melting point but above the eutectic temperature of the charges. In the embodiment described, a transistor is made from an indium doped germanium wafer provided with an arsenic or antimony doped base region. The wafer is placed on a heating block in an evacuated or inert gas-filled chamber and covered with an apertured mask. A charge consisting of indium doped germanium with a resistivity approximately that of the wafer and aluminium, preferably in eutectic proportions, is loaded into an evaporating filament, deposited on the wafer, and subsequently alloyed thereto to provide an emitter contact. To perform the alloying the wafer is raised from the temperature at which the charge is deposited to the alloying temperature and held at this temperature for 5-10 minutes before being returned to the deposition temperature, in contact to the more usual rapid heat/coal alloying spike. Another evaporating filament is so positioned that a base contact may be evaporated through the same mask aperture. In this case the charge consists of antimony doped germanium and gold. A similar procedure is followed to obtain the alloyed contact. To complete the transistor the wafer is provided with a collector contact, mounted on a header, and canned. In practice a large wafer is used in conjunction with a multi-aperture mark to provide many emitter and base contact regions and the wafer cut to provide a plurality of transistors. The method may be used with silicon and other semiconductor materials and may be used to form alloyed contacts in the production of diodes, transistors, and other semi-conductor devices.
