Title: A process for the production of cross-linked plastics of high molecular weight
IPC: C08G18/84
Filed: 1958-12-31
Abstract: A process for the production of cross-linked plastics comprises reacting formaldehyde with the reaction product of a polyisocyanate, a polyether containing oxygen and/or sulphur bridges and, as modifying agent, an N-di-(hydroxyalkyl) arylamine and/or a hydroxyalkyl phenol ether.  The term "formaldehyde" denotes formaldehyde, substances liberating formaldehyde or compounds with at least two methylol groups which may, if desired, be etherified.  The modifying agent can be incorporated by etherification during the production of the polyether, or the specified reactants (before the addition of the formaldehyde) may be reacted altogether or in stages in different orders.  The proportions may be chosen so that the modified compound has either terminal hydroxyl or NCO groups, both classes of compound being capable of cross-linking with formaldehyde. The polyisocyanates may be aliphatic, aromatic or hydroaromatic.  In the reaction giving the isocyanate-modified polyethers other bifunctional reagents may be present, such as water, aliphatic and aromatic diamines, glycols, and derivatives thereof which contain urea or urethane groups.  Hydroxyalkylated amines specified are reaction products of alkylene oxides, e.g. ethylene oxide, with aromatic amines, for example 4- or 5-amino-1,3-dimethyl benzenes, to give the N-di-(b -hydroxyethyl) derivatives, and also the reaction products of 2 mols. of ethylene oxide with xylidines, toluidines or aniline.  Suitable cross-linking agents are formaldehyde in solution, semi-acetals of glycol and diethylene glycol, paraformaldehyde, hexamethylene tetramine, trioxane, dimethylol urea, hexamethylol melamine or their ethers, polymethylol compounds of hexamethylene diurea, adipic acid dimethylolamide, and copolymerization products of methacrylamide methylol methyl ether and polymethyl compounds of polycaprolactam.  These cross-linking agents can be rolled into the other material together with carbon black or silica.  There may also be added catalysts such as inorganic or organic acids, substances splitting off acids, acid salts, zinc chloride or its complexes, and organic bases or metal oxides.  Together with the formaldehyde there may also be incorporated additional amounts of polyisocyanate. Hydroxyalkyl phenol ethers are reaction products of dihydric phenols with alkylene oxides.  In typical examples: (3) a dried mixture of a hydroxy polythioether, a polyethylene glycol and 5-N-di-(b -hydroxyethyl)-1,3-dimethyl benzene is heated with hexamethylene diisocyanate.  The melt is heated further, and then carbon black, paraformaldehyde and zinc chloride are incorporated and the mixture is cured at 150 DEG  C. Other examples employ polybutadiene glycol or polybutylene glycol as the polyether and di-b -hydroxyethyl resorcinol as the modifying agent.

Abstract: 1,086,129. Facsimile recording apparatus. MOTOROLA Inc. Oct. 5, 1965 [July 30, 1965], No. 43315/65. Headings H4F. A current-sensitive recording sheet 48 is pulled from a roll 14 by a driven roller 15, which coacts with a pressure roller 40, and is scanned in the transverse direction by electrode structures 45 carried by a belt 34, which loops around the sheet, the electrode structures comprising V-shape resilient bodies printed with five (or more) electrodes and being supported in holes formed in the belt. During the traverse of the recording zone the electrode structures pass between the sheet and a flexible channel member 42 printed with parallel conductors whereby they are pressed into contact with the sheet at one end and connected to receive signals to be recorded at the other. One end portion of an electrode structure has the same width as channel member 42, whilst the other end corresponds to the height of the recording to be produced. The central portion has a notch in each side for engaging the belt. In one arrangement, Fig. 4A (not shown), the holes in the belt are of rhombic shape with two different diameters. An electrode structure is passed through a hole with its smaller end parallel to the longer diameter and is then twisted through 90 degrees so that it is held along the shorter diameter. In another arrangement, Fig. 4B (not shown), the holes are semicircular with the straight side of the same length as the smaller end of an electrode. The belt is inclined to the horizontal and twisted (see Fig. 1, not shown), so as to allow for the sheet movement and cause marking in parallel lines. The recording sheet comprises a first layer of current-sensitive material (which is contacted by the electrodes), a second conducting layer and a third insulating layer. The marking current circuit is completed via pressure roller 40, which is conductive, and a conductive guide plate 50. Head shields 65 at each side of the sheet prevent the electrode structure engaging sheet 48 except in the recording zone. Drive to roller 15 and a sprocket for the belt extends through a one-revolution clutch (see Fig. 1, not shown).A high-speed drive is. also made to the roller for rapid paper advance.

Filed: 1962-11-09
Abstract: 991,327. Multicolour dyeing yarns; mottle treating yarns. TOYO RAYON KABUSHIKI KAISHA, and E. KAWARABAYASHI. Nov. 9, 1962, [Nov. 10, 1961], No. 42396/62. Headings D1B, D1F and D1L, [Also in Division H2] A method for mottle treating a running yarn 1 comprises vibrating the running yarn by an electro-magnetic vibrator (see Division H2) at a point 4 thereby bringing the yarn into intermittent contact with a yarn treating device 5 provided within the amplitude of vibration of the yarn. For liquid treating e.g. with dye liquor, resist printing liquors, dye pastes, resin liquors or swelling agents, the treating device may comprise a nozzle or a roller; for heat treating e.g. to release crimp a heated roller may be provided. Two spaced rollers may be used dyes of different colours so that a colour mottled effect is produced. Yarns to be treated may be of natural fibres, regenerated cellulose and cellulose acetate fibres, synthetic fibres or may be spun yarns or continuous, filaments comprising mixtures thereof. For dyeing synthetic fibres such as polyamide, polyester, polyacrylonitrile and polyolefin fibres dyes such as dispersed dyes or oil dyes in which has been blended a swelling agent or solvent are used; a conventional carrier may be blended in these dyes. Suitable swelling agents or solvents would be phenol, formic acid and calcium chloridemethanol for the polyamide fibres; chlorobenzene, benzyl alcohol and ethane tetrachloride for the polyester fibres; benzene and carbon tetrachloride for the polyolefin fibres; and zinc chloride-methyl alcohol, phenol and meta-cresol for the polyacrylonitrile fibres. As carriers, surfactants, polyethylene oxide and the like may be used. In addition salts may be mixed in the dye liquor. It is also possible to use a dye having a hydrophilic group or an azoic dye comprising a coupling component and a diazo component. The viscous dye compositions used in print dyeing are preferred. Subsequent to dyeing, steps of heating, washing and drying may be performed. The heating step may be performed by hot air, infra-red means, a heating wheel or a heated tube through which the yarn is passed. An untwisted yarn may be mottled with a paste and then twisted to produce a yarn having alternate twisted and untwisted parts where the paste has applied. After weaving or knitting the paste may be dissolved to produce a fancy effect. A yarn may be mottled with an adhesive and other substances adhered to the treated parts.

Abstract: 1285956 Transistor bi-stable and switching circuits WESTERN ELECTRIC CO Inc 27 Aug 1969 [27 Aug 1968] 42607/69 Heading H3T [Also in Division G4] In a binary store (see Division G4) a matrix array of transistor bi-stables (Fig. 2) is connected in rows to a number of "word lines" 109 and in columns to a number of "digit lines" 107, 108 via diodes 105, 106. During stand by period the diodes 105, 106 are reversed biased due to the voltages on the word and digit lines. When a read or write operation is to be made on a selected bi-stable the voltage on the word line connected to the row in which the selected bistable lies is reduced by the corresponding word select circuit (Fig. 5). Each word select circuit comprises a multi emitter transistor which functions as an "AND" gate and when supplied with the correct inputs diverts the current flowing in the line from two Schottky barrier diodes 68, 69 through the transistor 67 thereby reducing the voltage in the line 109. If a read operation is to be performed the digit detector (Fig. 7) is energized and the voltage difference appearing between the line 109 and the lines 107, 108 is coupled through the emitter follower inputs 201A and 201B and through diodes 203A and 203B to the bases of detector transistors 205A and 205B. Transistor 207 is then switched on by a timing signal at 208, the diodes 203A and 203B are reversed biased and the voltage difference on the bases of detector transistors 205A and 205B causes one of these transistors to switch on. The transistors 205A and 205B then remain in this state due to their bi-stable configuration. During a read operation the write driver (Fig. 6) coupled to the digit lines 107, 108 is switched by applying 0À7 volts to the inputs 80, 90 and 93 and presents a high impedance to the digit lines. In a write operation 0À7 volts are applied to input 93 and one of the transistors 81, 89 is switched off by grounding the respective input 80, or 90. Current then passes through one of the transistors 83, 87 into the selected digit line causing the selected matrix bi-stable to be set or reset. The complete circuit is made on a monolithic integrated circuit by selective etching and field effect of junction transistors may be used.

Abstract: 1282401 Pipe couplings; fluid pressure brakes EXACTOR STERLING Ltd 4 Sept 1969 [11 Sept 1968] 43111/68 Headings F2F and F2G Two co-operating parts 10, 60 of a twin fluid line coupling, each comprising two fluid passages 65, 66, 17, 18, sealed by valves, are coupled together, locked and the valves are then opened. The locking means comprises a sleeve 43 which, with parts 10, 60 in position, slides axially along part 10 towards part 60 and depresses a series of balls 15, held in a sleeve portion 13 of part 10, by means of a taper 50, so that the balls engage in a groove 63 in the periphery of part 60, thereby locking the two parts. Further axial movement of the sleeve 43 towards part 60 causes the taper 50 and another taper 51 to depress four spring controlled plungers 67, 32 which open valves 33 in both parts by tilting the valve spindles 30, 68, 69. Part 10 carries a spring loaded plunger (47) Fig. 2, (not shown), which locates in a groove 48 in the sleeve 43 to retain the sleeve in the locking position. Location of the two parts 10, 60 is facilitated by hollow projections 74, of different diameters 4 containing the fluid lines in part 10 mating with matching sockets 72 in part 60. For use in a vehicle braking system, whereby part 10 is mounted in a tractor and part 60 is mounted on a trailer, the two fluid lines in part 60 are interconnected by a fluid line 81, (82), 83 containing a tilt valve controlled by a plunger (87) Fig. 2 (not shown), which protrudes from the mating face of part 60. The valve is open when the parts 10, 60 are uncoupled, thus allowing fluid to flow between the fluid lines 65, 66 in the braking system, from high pressure source to the brakes, keeping the trailer brakes applied. During mating of parts 10, 60, the plunger (87) is depressed, thus closing the interconnecting passages and placing the trailer under control of the tractor. A manual overide button (93), Fig. 6, (not shown), used to allow the trailer to be unbraked when required, is depressed when the parts 10, 60 are coupled, and locks the plunger (87) in the retracted position so that the valve interconnecting fluid lines 65, 66 remains closed when the parts are subsequently uncoupled. The tilt valves, Fig. 5 (not shown), each comprise a stem which screws into a flange part (33A), the stem and flange each having a taper retaining a sealing ring between the two members, the sealing rings abutting shoulders in the fluid passages when the valves are closed. Porous discs 77 are provided in the fluid passages near the mating faces of the parts 10, 60, which allow flow of fluid when the valves are open, but retain fluid in the passages by capillary action when the parts are uncoupled.

Abstract: 1,114,779. Power-assisted steering. CAMGEARS (CLEVEDON) Ltd. 18 Oct., 1966 [11 Oct., 1965], No. 43129/65. Heading B7H. A control means for use in an hydraulic power-assisted steering or other hydraulic system has a torsionbar 6 which transmits rotary motion between first and second parts 1a 9 of the system and has valve members 10 formed thereon, which are rotatable with the second part 9 and co-operate with two fluid-flow orifices 11 in a valve body 1 rotatable with said first part 1 to vary the pressure in two opposed hydraulic operating circuits. As shown, the first part 1a is secured to a steering shaft 12, the second part 9 rotates a pinion 22 in mesh with a steering rack 23 and the two opposed hydraulic operating circuits communicate with opposite sides of a servo piston through ports 21. In the neutral steering position pressure fluid-flow from inlet 17 is divided equally by axiallybored shuttle valve 16 and passes to the orifices 11 through respective annular passages 14 and axial passages 13 of the valve body 1. The exhaust from the orifices passes back to the pump supplying the inlet 17. On relative rotation of the valve parts during steering movements (Fig. 4), the portion 10 of the torsion-bar 6 acts as a flap valve producing at the orifices 11 a differential pressure which is communicated through drillings 13 and annuli 14 to the ports 21 to move the servo-piston and through the drillings 14 and ports 18 to the opposite sides of the shuttle valve which moves so as to provide a greater flow to the high pressure side of the servo-piston. In modifications, shuttle valve (30) is provided with bores (34) through the lands and ends which coact with coaxial bores in the valve housing (Fig. 5, not shown), or two constant output fluid supply pumps are provided.
