Title: Polyamides and process for their preparation
IPC: C08G69/08
Filed: 1965-06-25
Abstract: Polyamides are prepared by condensing one or more aliphatic aminocarboxylic acids, at least one of which has an aromatic or heterocyclic substituent directly attached to an aliphatic carbon atom and/or one or more aromatic aminocarboxylic acids in the presence of phosphorus pentoxide, a di-alkyl phosphite each alkyl radical of which contains 1 to 4 carbon atoms and concentrated sulphuric acid, gaseous hydrochloric acid or a Lewis acid.  The polyamides suitably have a molecular weight of 12,000 to 50,000. Preferably the aromatic aminocarboxylic acids do not contain condensed nuclei and suitable aliphatic and aromatic aminocarboxylic acids are 4,41-diamino-diphenyl-methane-3,31-dicarboxylic acid, 4-nitro-2-aminobenzoic acid, p-aminosalicyclic acid, 1-tyrosine, 1-alanine, 1-glutamic acid and lysine monohydrochloride.  The aromatic aminocarboxylic acids may also contain alkyl groups, halogen atoms, sulpho, hydroxy and nitro groups, the latter of which may be hydrogenated after polymerization.  The preferred dialkyl phosphite is diethyl phosphite whilst the Lewis acid may be aluminium trichloride or boron trifluoride.  The polyamides having a M.W. of 12,000 to 50,000 are claimed as new compounds. missing page 26

Patent GB-700555-A (GB)
Title: Process for producing regenerated cellulose filaments or fibres from viscose
IPC: D01F2/06
Filed: 1950-11-13
Abstract: Regenerated cellulose filaments and fibres are obtained by a two-stage spinning process which comprises extruding viscose into an aqueous coagulating bath having a pH of 1.5 to 10 and containing sodium sulphate and inorganic phosphate radicals, at least some of which are in the form of a sodium salt, withdrawing the xanthate filaments thus formed, passing them through an aqueous cellulose-regenerating bath containing an equilibrium mixture of sodium sulphate and phosphoric acid and also sulphuric acid to convert at least part of the phosphate salts carried over by the filaments to phosphoric acid, stretching the filaments between the coagulation and complete regeneration operations, continuously passing at least a portion of excess regenerating bath which builds up during spinning to the coagulating bath, withdrawing a portion of the coagulating bath and removing therefrom, by evaporation and crystallization, water and sodium sulphate, and maintaining the composition of the coagulating bath substantially constant by the addition of predetermined amounts of sulphuric acid and phosphoric acid from a source other than the regenerating bath.  In effect, it is the sulphuric acid that is consumed for the neutralization of virtually all the sodium hydroxide in the viscose, the phosphate radicals serving to dehydrate the viscose stream and as a vehicle to carry hydrogen ions to the stream for neutralizing the sodium hydroxide.  There is substantially no loss of phosphate radicals. The filaments may be stretched between the coagulating and regenerating baths and relaxed in the regenerating bath. Alternatively they may be stretched in the regenerating bath. Crimped filaments may be obtained by employing a high jet velocity-draw-off ratio.

As described, a reversible synchronous motor 1, Fig. 1, normally rotates the shaft 4 through gearing 2a-2g, 3 the latter being connected by a friction clutch 6-10 to a gear 5 fixed on the shaft 4. The gear 5 meshes with the outer ring 14, Fig. 2, of a free-wheel one-way clutch 12. Keyed to the shaft 4 are a plurality of annular members 21, Fig. 5, frictionally mounted on each of which is a pair of graduated rotary members 19 angularly adjustable with respect to a reference line 26 on a lug 25 on the member 21. Each member 19 of a pair has a circumferential groove 20 in which dogs 39 and 47 are located by means of grub screws. As the shaft 4 rotates each dog 39 raises a corresponding operating lever 31 which actuates a pilot valve or switch 23. The lever 31 is latched in its operative position by a latch 32 which is subsequently moved by the associated dog 47 to release the operating lever 31. The amount of the rotation of the shaft 4 is indicated by a reference wheel driven from the shaft and viewed through a window. The final operating member 31 of the series actuates a switch to cause the motor 1 to rotate in the reverse direction and the shaft 4 is driven forwardly at greater speed to its zero position through the gears 2a, 2b and the clutch 12. The associated dog 47 then releases the final lever 31 and the cycle of operations begins again or a switch may be operated to stop the motor 1 when the shaft 4 is in the zero position.

Title: Improvements in or relating to polystyrene compositions and mono- and multifilamentary materials produced therefrom
IPC: D01F6/20
Filed: 1954-09-29
Abstract: A composition for making artificial filaments comprises 80-98 per cent of polystyrene and 20-2 per cent of a copolymer consisting of (1) a binary copolymer of styrene and at least 20 per cent of acrylonitrile or (2) a ternary copolymer of styrene and at least 20 per cent each of acrylonitrile and alpha-methyl styrene.  The ternary copolymer may consist of about 35 per cent styrene, about 30 per cent acrylonitrile and about 35 per cent alpha-methyl styrene, and may comprise about 8 per cent of the composition, the balance being polystyrene.  The composition may be melt-spun to form a monofilament, which is cooled to below its melting-point either in a gaseous medium or in a liquid non-solvent bath, stretched to effect orientation, and then twisted or flexed to effect longitudinal rupture or splitting of the monofilament into a multiplicity of long continuous filaments, with little or no transverse rupture of the monofilament or of the finer filaments into which it splits.  After the monofilament has been twisted and split longitudinally, the resulting bundle of filaments may be held so that the twist is maintained, and may be heated at about 80 DEG  C. while thus held in order to set the twist. In a series of examples mixtures of 80-98 per cent of polystyrene with 20-2 per cent of the above ternary copolymer are extruded at about 460 DEG  F. through an orifice 0.1 inch in diameter, the hot extruded monofilament formed being withdrawn from the orifice by a pair of rubber draw-rolls operated at a speed to reduce the diameter of the filament to 0.075 inch and positioned a distance from the orifice sufficient to permit partial cooling of the monofilament to about 230 DEG  F. before stretching occurs.  The partially stretched filament, after passing around snubbing rolls, is stretched further at a ratio of 5.8 to 9.2 by a second set of draw-rolls to reduce its diameter to about 0.02 to 0.03 inch.  The resulting oriented filament is twisted about its longitudinal axis or flexed several times to split it into a multifilamentary strand, which is heated for about an hour at 80 DEG  C. to set the twist permanently.

Title: Mechanism for automatically adjusting the operation of steam pressure regulators in steam heating systems
IPC: F24D19/10
Filed: 1933-10-13
Abstract: 414,544. Heating buildings. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Nash Engineering Co. ; South Norwalk, Connecticut, U.S.A.) Oct. 13, 1933, No. 28327. [Class 64 (ii).] In the automatic control of the steam pressure regulator of a steam heating system wherein the regulator valve is operated by a mechanical element, the element is automatically adjusted to meet varying temperature conditions by means of thermostats arranged outside and inside the chamber to be heated. The regulator valve h, Fig. 1, is moved up or down according to the position of weights 16, 17 movable along a bar 15 which presses on valve stems I, I<1>, the position of the weights being determined by a screw 24 which is rotated by a motor 22, Fig. 6, under the control of the outside and inside thermostats. A thermostat 50, which constitutes the basic setting of the regulator according to weather conditions, sets into operation a motor 49, which co-operates with a motor 45. The shaft of the latter carries an adjustable cam 44 which bears against the hub of a control rod 39, Fig. 8, one end of which is pivoted to a shaft 36, which rocks a group of mercoid switches M-M<1>, N and O, Fig. 9. The intermediate part of the control rod engages a bearing on a follow-up bar 41 which is arranged between the weights 16,17 ; movement of the bar 41, therefore, rocks the mercoid switches. Two inside thermostats, T, T<1>, Fig. 14, supplement the setting effected by the thermostat 50 and limit switches L, L <1> prevent the weights from being moved too far. In operation, the inner thermostats being set to throw at deviations from the desired temperature, the thermostat 50 causes the rotation of the cam 44, which turns the control rod 39 to right or left thus rocking the mercoids M-M<1>. These cause the motor 22 to be set into operation and effect control. The follow-up bar 41 now rocks the control rod 39 restoring the switches M-M<1> to normal. If the temperature rises or drops below the setting effected by the outside thermostat, the inside thermostats allow current to flow to the motor 22 and the movement of the regulator is corrected accordingly. In modifications, the mechanical element may be replaced by a spring mechanism and the switches may be replaced by a single mercoid with one inside thermostat.
