Title: The manufacture of fibres, filaments and films from molten material
IPC: C03C13/00
Filed: 1967-11-20
Abstract: 1,210,920. Continuous casting-machines. MONSANTO CO. 20 Nov., 1967 [22 Nov., 1966], No. 52697/67. Heading B3F. In the streaming or spinning of fibres, filaments or films through an orifice 16 of a crucible 14, the operating parameters affecting the aerodynamic drag on the filament as it passes through a chamber 12 are controlled so that any drag-sustained deviations are prevented from migrating upstream towards the still liquid part of the filament. The crucible 14 is induction heated by coils 32 and is pressurized to force molten material, e.g. lead/tin alloy, pure tin, stainless steel, boron and aluminium, or an alumina-calcia mixture, out of the orifice 16, which may be formed in a jewel material set in the crucible. The chamber 12 may have a gas, e.g. helium, oxygen, or a mixture thereof, or a helium/propane mixture, circulated therein in either direction through ports 40, or the gas may be stagnant. The operating parameters are controlled to maintain the velocity of propagation of the-drag-sustained deviations less than the velocity of the filament. Theoretical considerations and formulµ relating to the effects of varying the operating parameters are included in the Specification. A plurality of orifices 16 may be provided in the jewel material. Specifications 1,197,972 and 1,153,577 are referred to.
Patent GB-528312-A (GB)
Abstract: 528,312. Acyl-styrenes ; synthetic resins. ARMOUR & CO. March 24, 1939, No. 9292. Convention date, April 11, 1938. [Class 2 (iii)] Acyl styrenes are prepared by reacting styrene with a fatty acid chloride having at least twelve carbon atoms in the molecule, in the presence of a Friedelcrafts' catalyst, and hydrolyzing the intermediate product formed. Examples describe the preparation of stearoyl-, oleoyl, linoleoyl-, linolenoyl-, and lauroyl-styrenes by slowly adding the fatty acid chloride to a cooled solution of styrene in chlorobenzene in which aluminium chloride is suspended, and gently heating ; the reaction mixture is then hydrolyzed with ice and the solvent removed by steam distillation. The use of myristoyl and palmitoyl chloride is referred to ; also of mixed fatty acid chlorides, e.g. those prepared from the fatty acids of coconut oil, lard, cottonseed oil, fish oils, linseed oil and the synthetic fatty acids derived from the oxidation of paraffin wax and similar hydrocarbons. The acyl styrenes are useful as plasticizers for resins, especially styrene and vinyl resins; they themselves rapidly polymerize to transparent, flexible, glass-like solids and also react in all proportions with styrene and vinyl compounds to give very plastic, transparent resins. The Specification as open to inspection under Sect. 91 states that the products may be incorporated in paints and lacquers to impart elasticity to the films or may be dissolved in organic solvents and used as lacquers per se. The products prepared from unsaturated fatty acid chlorides polymerize more readily than those prepared from saturated acid chlorides. Reference is made to the polymerization of stearoyl-styrene at room temperature or by heating to 100‹C., and to the polymerization of mixtures of the stearoyl-styrene with styrene in which the percentage of the former is varied between 2 and 75 per cent. This subject-matter does not appear in the Specification as accepted.

Abstract: 1442843 Sliding windows SOLVAY & CIE 15 Nov 1973 [16 Nov 1972] 53072/73 Heading E1J A horizontally sliding window comprises two panels 1, 2 slidable in a casing which has an upper cross-bar 3 with a ridge 10 and provided with leak-proof gaskets 4, 5, 6, 7, 11, 14, 15. When the window is closed the gaskets 4, 5 are in contact with the undercut ridge 10, the gaskets 6, 7 close the central gap between the panels and the gaskets 14, 15, which act as extensions of gaskets 6, 7, contact gasket 11 which is attached transversely to ridge 10. When the window is to be opened the panel is first lifted by handle means causing it to tilt away from the vertical due to the angled strips 18, 19, 20, 21 acting on the fixed guides 26, 27 and break contact between the various gaskets; this allows the panel to slide freely. On releasing the panel tilts back into position and the gaskets resume contact.
Patent GB-1113374-A (GB)
Title: Improvements in or relating to a method for expanding articles of foamable polymeric material
IPC: C08J9/224
Filed: 1965-12-14
Abstract: Individual strands of expanded polymeric material are made by coating strands of foamable polymeric material with an anti-coalescing agent in an amount sufficient to prevent the strands coalescing during expansion.  The expansion is unconfined in at least one direction, and is effected by partially filling a closable vented chamber with the strands so that the ratio of the volume of the chamber occupied by the unexpanded strands to the total volume of the chamber is not more than the ratio of the bulk density of the expanded strands to that of the unexpanded strands, closing the chamber, and heating the strands to cause them to individually expand without subsequent coalescence. The polymeric material is preferably a polymer of a monovinyl aromatic compound, e.g. polystyrene, but may also be a methyl methacrylate or aliphatic olefin polymer, and contains a volatile organic foaming agent, e.g. pentane.  Suitable anti-coalescing agents are stearic acid and its salts, e.g. magnesium stearate, silicones, sodium oleate, talc, tricalcium phosphate, potassium lauryl sulphate and combinations of these.  The strands are initially about 4 to 5 inches long and 0.125 inch in diameter.  When expanded they are suitable for use in packaging.

Title: Electrical control apparatus, particularly for heating installations
IPC: F23N5/20
Filed: 1969-10-31
Abstract: 1293581 Burner control DANFOSS AS 31 Oct 1969 [9 Nov 1968] 53489/69 Heading F4T Control equipment for starting up and monitoring a heating installation comprises a relay A which operates a contact A1, thus operating motor M or a fuel valve, in series with a parallel combination of a resistor R, and a monitoring switch F1 which opens when a flame is detected, the switch F1 also being part of a parallel path 8 which by-passes the relay and resistor, the resistor R 1  being rated so that the relay can be energized only when the switch F 1  is closed, but remains energized when switch F1 is opened by virtue of the current flowing through the resistor R1. In operation the closing of a thermostat KT energizes the heating coil T of the slow acting switch T1 which on closing causes current to flow through an ignition transformer ZT and operates relay A, the resulting flame causing the switch F 1  to open, thereby de-energizing heating coil T and eventually causing switch T 1  to open and cutting off the supply to the ignition transformer. If the burner fails to ignite and switch T 1  remains closed a heater V energizes slow acting switch V 1  cutting off the supply to the relay and motor and operating the warning lamp G. If the flame fails during operation the switch F 1  is closed causing relay A to be de-energized because current passes through low resistance path 8 thereby stopping the motor M. In a modification the relay contacts operate a fuel valve. In a further modification two fuel valves are operated by the relay, one of which is in a circuit containing a modified two-position switch T 1 , the circuit being closed when the switch is in the cooled-down position.

Abstract: 1487310 Corona charging apparatus IMPERIAL CHEMICAL INDUSTRIES Ltd 13 Nov 1974 [21 Nov 1973] 53940/73 Heading H1X [Also in Division H2] Apparatus for charging particles comprises a duct with at least its inner surface conducting, a stream of insulating gas carrying the particles through the duct, an earthed corona discharge electrode within the duct and means for applying a voltage to the inner surface of the duct. As shown, a fan 16 blows air, in which particles are entrained, round a circuit comprising a tube 10 made of conductive material and tubes 12, 14 made of insulating material. A wire 18, held coaxially in tube 10 by insulating supports 20, 22, is earthed by a wire 19 passing through an insulator 24 in the wall of tube 10, which is connected to a high voltage generator 26 so that a corona discharge occurs between wire 18 and tube 10. Tube 14 is surrounded by a toroid 28 of conductive material, to which is connected a needle 30 projecting into tube 14. Because of the charge on the particles, the toroid 28, becomes charged through needle 30 to a very high voltage. Triboelectric charging may also take place, in which case the materials of the tubes and the powder are so chosen that the polarity of the triboelectric charge on the powder is the same as that produced by corona charging. The charged particles may be ejected from a duct instead of being circulated, and they may be liquid droplets instead of solid particles, or solid particles in a liquid.

A device for adjusting an adjustable floor 1 of a swimming-bath in a vertical direction comprises four hydraulic jacks, like the one shown, mounted two by two on opposing sides of the floor at a mutual distance. Each jack comprises a cylinder 2 with a piston having a piston-rod 3. Pressure oil is supplied through a pipe 4 by a separate pump for each jack. A pipe 5 provides for the discharge of water and oil which may get on top of the piston. The cylinder 2 rests on a bottom plate 6 and is prevented from rotating by a projection 17 attached to the inner wall of a pipe 11. The piston-rod 3 has a head 7 with three guide rollers 8 bearing against the inner wall of the pipe 11. A profiled section 12 is secured to the head 7 and engaegs a bearing roller 13 secured to the floor 1 by its shaft 14 which is received in a slot 15 when the jack is retracted. A roller 16 engages the sides of the slot 15 to prevent the head 7 from rotating. At the highest position, as shown, the profiled sections 12 and bearing rollers 13 allow the floor to be moved horizontally. When the jacks are retracted the floor is lowered, rollers 13 fitting accurately into the pipes 11. If, for any reason, the jacks do not move uniformly the floor is tilted out of the horizontal and the guide rollers 8 jam against the inner wall of the pipe 11, preventing further vertical movement of the floor 1. The pumps may be operated by a common electric motor, enabling one man to operate the device.

An overload release clutch comprises driving and driven rings 1 and 2 carrying dog teeth 21, 22 and drawn into engagement by a magnet or electromagnet 3 against a spring 6, the sides of the dog teeth being inclined so that when the transmitted torque exceeds a predetermined value the teeth cam over each other to move the members 1 and 2 axially apart until the air-gap 14 is too large for the magnet of electromagnet 3, and spring 6 disengages the clutch. As shown, the ring 1 is fast with a rotating electromagnet 3, and ring 2 is fast with armature 4. Again, the ring 1 may be bearing mounted on a stationary magnet or coil. To ring the predetermined overload torque, the coil 11 is in series with an adjustable resistance (12), Fig. 3 (not shown) which may be set to determine the coil current and hence engaging force of the electromagnet. A switch (10) is mounted parallel to the resistance to enable initial engagement of the clutch. Closure of the switch by-passes the resistance and allows maximum current to flow in the coil to engage the clutch. With the switch open, even when the resistance is at its minimum setting, the current is not large enough to engage the clutch across the air-gap 14.
