Patent GB-562184-A (GB)
Title: Improvements in and relating to regenerated cellulosic fibres, yarns, films and the like
IPC: C08L1/24
Filed: 1942-11-27
Abstract: A water-soluble polymerisation and condensation product, of intrinsic viscosity at least 0.5, formed by reaction between a dibasic carboxylic acid and a diamine containing at least two oxygen atoms in the chain separating the amino groups, is incorporated in an aqueous alkaline cellulosic spinning solution and the solution is formed into artificial fibres, yarns, films, and other structures.  The presence of the polyamide renders the regenerated cellulose products more receptive for wool dyes, particularly those capable of dyeing from neutral baths, and the dyeings are resistant to sunlight.  The polymer may be a simple polyamide or it may be obtained by interpolymerization of a polyamide-forming composition containing in addition to the reactants specified above, other linear polymer-forming reactants such as monoaminomonocarboxylic acids or mixtures of dibasic carboxylic acids with diamines other than those of the kind specified above.  The cellulosic solution may be viscose, cuprammoniumcellulose solution, or a solution of cellulose in a quaternary ammonium base.  The polymer may be present to the extent of 5-20 per cent of the weight of the cellulose.  It may be a polytriglycol adipamide of molecular weight at least 5,000. In an example, there is used an interpolymer made by heating together the adipic acid salt of triglycoldiamine and a minor proportion of the adipic acid salt of hexamethylenediamine, and in another example there is used a polyamide made by condensing the adipic acid salt of triglycoldiamine with a minor proportion of the adipic acid salt of decamethylenediamine.  Other diamines from which the polymers may be obtained are bis-(amino-propoxy)-hexane, tetraglycol diamine, and p-bis-(b -aminoethoxy)-benzene.  Instead of the diamines and dicarboxylic acids, there may be used as reactants for the production of the polymer, any amide-forming derivative of these compounds, e.g. esters, anhydrides, amides, or halides of dicarboxylic acids, or, in presence of water, nitriles, cyano-carboxylic acids, cyanoamides, or cyclic imides of dicarboxylic acids, or carbamate, N-formyl, or N : N1-diformyl derivatives of the diamines.  In examples, regenerated cellulose yarns, from viscose containing the polyamide addition, are dyed with the wool dyes of Colour Index Nos. 289, 430, 1088. Specifications 461,237 and 543,426 are referred to.

Title: An elastic coupling between an air-screw and a coaxial driving shaft
IPC: F16D1/08
Filed: 1934-06-07
Abstract: 440,804. Screw propellers. ARMSTRONG SIDDELEY MOTORS, Ltd., VIALE, S. M., and WYLIE, H. N., Park Side, Coventry. June 7, 1934, No. 16901. [Class 114] [See also Group XXIV] An elastic coupling between the hub 11 of an air-screw and its driving-shaft 12 comprises a plate 14 secured to the shaft between a pair of plates 13, 15 secured to the hub, with a rubber disc 16 interposed between and vulcanized or cemented to each adjacent pair of plates, the thickness of each disc 16 at any radial distance from the axis being proportional to that distance. The plates and discs may be conical. The plates 13, 15 may, as shown in Fig. 1, be connected to the hub 11 by bolts 18 which have clearance in holes in the discs 16 and in the plate 14, and which may serve to apply compression to the discs. The thrust of the air-screw may be taken by a washer 20 of friction material, so as to act as a friction damper, or of rubber fixed to a rigid plate 21. The hub 11 is centred on the shaft by a bush 22 of metal or of friction material. The plate 14 may have a cylindrical part 23 co-operating with a friction band 24 carried by the plates 13, 15. Alternatively, the plate 15 may have a sleeve portion 25, Fig. 3, surrounding a sleeve portion 17 of the plate 14, a series of oppositely-arranged conical washers 28 being interposed between the sleeves. These washers are urged into frictional contact with each other and with the sleeves by a nut 32 carried by the end of the shaft 12. Thus the frictional damping varies with the axial thrust of the air-screw. Alternatively, the washers may be urged into contact by a spring abutting against a member adjustably screwed in the sleeve 25. Specification 422,418, [Group XXIV], is referred to.

Title: Improvements in and relating to battery charging systems, particularly for batteriessupplying telephone installations
IPC: H04M19/00
Filed: 1930-06-02
Abstract: 356,165. Exchange systems. LOOG, C., 10, Berlinerstrasse, Wilmersdorf, Berlin. June 2, 1930, No. 17064. Convention date, Jan. 28. [Class 40 (iv).] Telephone exchange batteries are charged as required during use, the charging current being automatically regulated in stages by a series of relays which operate in accordance with variations in the load. In the arrangement shown, relays 1 .. 7 have main (lower) windings connected in series with the load 53 and secondary (upper) windings in parallel across the battery B. Normally all the relays are unoperated and the battery is not connected to the generator. When the load current rises to 2À5 amps., relay 1 operates due to both windings acting in conjunction and energizes relay 8 which connects the generator over resistance 39 to the battery, the value of this resistance being such that a charging current of 3À5 amps. is supplied. Relay 1 also inserts a resistance 154 in its own circuit and energizes upper (opposing) windings of relays 3 .. 7. When the load current rises to 5 amps., relay 2 operates over its lower winding alone, connecting its upper winding in partial opposition and energizing relay 9 which connects resistance 40 in parallel with resistance 39 thus increasing the charging current to 7 amps. When the load current rises to 9 amps., relay 3 operates increasing the current in the upper windings of relays 4 .. 7 to prevent them also operating at this time, and energizing relay 10 which inserts a third shunt resistance 41. Relays 4 .. 7 act similarly in response to further increases in the load current. When the load falls the relays release in succession but in reverse order to give corresponding control. Switches 46 . . 52 provide manual control of the charging current. In an alternative arrangement, the relays 1 .. 7 are all energized under no load and release successively in response to increases in load, only one however remaining de-energized at one time so that the resistances 39 .. 45 which are of different values are connected singly and not in parallel combinations.

Title: Apparatus for Forming Molten Glass or like Material in Cylindrical Form.
IPC: C03B17/04
Filed: 1916-11-29
Abstract: 111,521. Marks, E. C. R., (Libbey Glass Co.). Nov. 29, 1916. Drawing.-Relates to apparatus for drawing molten glass or like material, in either hollow or solid cylindrical form in accordance with the process described in Specification 110,642, and comprises an inclined forming mandrel or blow-pipe on to which the molten material flows and around which it is evenly distributed and from which it is drawn lengthwise. The molten glass is placed in a trough 3, Fig. 3, above a furnace 2, and, after flowing down a step to eliminate air bubbles, passes beneath an adjustable gate 11 and flows in a stream A on to the exterior of a hollow rotating mandrel 15, Fig. 2, situated in an independently heated furnace chamber 9. The mandrel, which may be adjusted longitudinally, whilst in action, projects into a casing 25 which is continuously rotated on wheels 26 so as to radiate heat uniformly to the glass upon the mandrel. The casing is enlarged at the exit portion 25<b> thereby allowing a slight cooling of the glass before leaving the mandrel. A ring-like door 44 carrying a trough 53 to catch falling particles from the mandrel closes the furnace opening around the casing 25. In operation, the stream A of glass winds around and flows down the rotating mandrel and is drawn off in the form of a tube B by means of any suitable drawing-device. air under slight pressure or at atmospheric pressure being continuously supplied through the mandrel. In drawing a solid rod, the end of the mandrel is closed by an imperforate tip. In a modification, Fig. 11, the mandrel is surrounded by a conical casing 43 which is partially filled with molten glass, the thickness of the glass film being regulated by the size of the outlet. In a further modification, the rotating shell enclosing the mandrel is replaced by a stationary housing 68, Fig. 14, and the molten glass in the furnace trough is shielded from direct contact with the flames. The mandrel is rotatably mounted in a bearing 72 carried by an arm which may be adjusted so as to vary the inclination of the mandrel without varying the height of the stream A of glass. The wide end of the housing 68 is closed by a vertically sliding door 81 with the exception of a slot 82 for the passage of the drawn glass, and the slot is restricted by a pair of suspended plates 87, these closures affording means for regulating the temperature of the housing 68.
