Title: Continuous filament yarns and a process and apparatus for making them
Inventor: CANNON CYRIL GEORGE
IPC: D02G1/00
Filed: 1964-06-19
Abstract: 1,102,095. Spinning; finishing and testing yarns; winding bobbins. IMPERIAL CHEMICAL INDUSTRIES Ltd. 17, June, 1965 [19, June, 1964], No. 25416/64. Headings D1F, D1J and D1W. A yarn composed of one or more continuous, synthetic e.g. polyamide, polyester, polyhydrocanbonate, or polyurethane, filament(s) comprises a multiplicity of interconnected loops arranged essentially parallel to the longitudinal axis of the yarn with many of the loops contained for at least part of their length within another loop and with a number of, perhaps shorter length, loops wrapped e.g. as a discontinuous sheath, around the body or relatively compact core of the yarn. The yarn is stated to possess an air drag factor of at least 7.5, a bulk factor, i.e. the percentage change in the diameter of the yarn on the application thereto of a given load (as detailed in the specification) of at least 1.3, and a twist factor i.e. actual twist divided by the square root of the cotton count, of at least 0.75. The air drag is measured by incorporating a length of the yarn in a pendulum arrangement (a two metre length clamped at one end and with a 4 grm. weight attached to its opposite end) and determining the number of swings between amplitudes of 30 and 20 on one side as the oscillatory movement of the pendulum is damped by air resistance. The air drag factor is then equal to the product of the fourth power of the drag and the denier divided by 10<SP>2</SP>.  The yarn is produced by passing an extruded continuous filament 20 (or up to, say, 50 thereof) to a rotating body 22 around which it is wound. The body has a peripheral speed sufficient to tension, attenuate and molecularly orient the filament, and a reciprocating movement is imparted to the filament by a traverse mechanism 25 whereby it moves back and forward along the body so as to form a constantly acccumulating sleeve thereon. The sleeve is continuously withdrawn from the body so as to impart twist to the coiled filaments. Simultaneously therewith, the sleeve is everted by pulling it, in the form of a strand 27 of complex interconnected loops, in the reverse direction through an axial bore or passage 23 and hollow driving shaft 24 of the body, a guide 28 to take-up bobbin 30. The process, materials and apparatus are the same as described in Specification 1,082,401 except as regards provision for evertion of the sleeve through hollow rotating bodies, as at 22.

Title: Repeaters for multiplex signalling systems
IPC: H04J1/10
Filed: 1920-09-03
Abstract: 151,600. Western Electric Co., (Assignees of Affel, H. A.). Sept. 26, 1919, [Convention date]. Multiplex systems; repeating systems.-In a multiplex system in which high-frequency carrier currents are modulated by low-frequency signals, and in which a two-way repeater is included in the transmission line, the eastbound and westbound carrier currents belong to different ranges of frequency, so that they can be confined by filter-circuits to their proper paths in the repeater. Exact balancing of the repeater transformers is thus rendered of less importance. In the system illustrated, low-frequency signal circuits L1, L2, L3 control modulators M1, M2, M3, operating at 5000, 8000, and 11,000 cycles. The modulated eastbound carrier currents pass to line ML through filters TF1, TF2, TF3, each adapted to transmit the corresponding carrier frequency, an amplifier TA, a filter TF which transmits all frequencies in the eastbound range but rejects those in the westbound range, and a balanced transformer 10 connected between the line ML and an artificial line MN. At the repeating station, the eastbound currents pass through a balanced transformer 20 (between the line ML and an artificial line N) an amplifier AE and transformer 20' to line ML<1>. Filters EF, EF<1>, on each side of the amplifier AE, transmit frequencies in the eastbound range but reject these in the westbound range. Westbound signals are carried by currents of frequencies 15000, 18000, and 21000 and pass through filters WF, WF<1> and an amplifier AW. At the terminal station they pass through a filter RF, which transmits westbound frequencies but not eastbound, and through an amplifier RA and filters RF1, RF2, RF3, which transmit the individual carrier frequencies, to homodyne detectors D1. D2, D3, which deliver the low-frequency signals to the circuits L1, L2, L3. The amplifiers, modulators and detectors may be of the vacuum-tube type. The filters may be either band filters or tuned circuits.

Filed: 1966-06-09
Abstract: 1,102,889. Moulding tyres. McNEIL CORPORATION. 9 June, 1966 [23 Oct., 1965], No. 25740/66. Heading B5A. A tyre press has opposed mould sections 20, 21 and a central tyre curing bag 51 comprising an open-ended radially distensible cylinder, its lower end closed by a ring assembly 75, 76 held against the lower mould section, and its upper end closed by a ring assembly 54, 55 carried on an axially adjustable central shaft 100. Radially movable elements 62 supported on the upper ring assembly are movable outwardly to contact the bag, when collapsed, by an actuator 70 slidable on the shaft 100 and moved vertically by a shaft 101. The two shafts are enclosed in a housing 95 having an open end communicating with the bag interior, and are driven by a mechanism 115, Fig. 7, extending transversely of the housing. Curing media is supplied to a manifold 104, having aligned bores for the passage of the shafts 100, 101, and passes therefrom into the bag. The ring 75 is clamped down by a number of rods 82, with ring engaging heads 85, which are attached to a toothed ring 202 engaging teeth 201 on a sleeve rotated about the housing 95 by a driven gear 206. After curing, when the tyre is raised from the lower mould section by the shaft 100, and the bag is brought to its cylindrical form condensate of the curing media passes through the ring 75 and housing 95 and is drained away at the bottom thereof. The shaft drive.-The shafts 100, 101 are driven together or independently by a mechanism including a primary drive shaft 125 which drives the shaft 100, and a secondary drive shaft 126 which drives the shaft 101. The shafts 125, 126 are provided respectively with output gears 127, 129 engaging rack teeth extending longitudinally of the shafts 100, 101. A gear 150 on the power input end of the shaft 125 is engaged by the teeth of a fan-shaped gear segment 152 driven in either direction about an axis (187), Fig. 3 (not shown), by a double-acting fluid cylinder (116). The power input end of the secondary shaft 126 has a spline gear 153 engaged by double-acting pistons 166a, 166b having circumferentially continuous rack gear teeth. The pistons are enclosed in a housing 155 clamped to the shaft 125 so that the shafts may be locked together for common movement. Rotation of the secondary shaft 126 in either direction independently of the primary shaft is effected by the supply of fluid pressure into the ends of the piston compartments 162a, 162b simultaneously. Such fluid supply is controlled by a rotary valve 160 supplied with fluid by conduits 171a, 171b, whereby fluid is led to both ends of the piston compartments as desired via ducts 173a, 173b, 174a and 174b. Movement of the gear segment 152 to raise or lower the shaft 100 in response to actuation of the cylinder (116) may be electrically controlled by a series of switch actuators carried by the gear segment and actuating an adjacent switch.

Title: Method of manufacturing lead-acid batteries
IPC: H01M50/529
Filed: 1972-06-03
Abstract: 1427325 Lead-acid batteries JOSEPH LUCAS (BATTERIES) Ltd 22 May 1973 In a method of manufacturing lead-acid batteries firstly the required intercell connections are formed between packs of battery plates through the integral partition walls which divide the thermoplastics battery box into compartments, then the compartments are filled with the acid which is to define the electrolyte of the battery in use, and lastly a thermoplastics lid is secured to the thermoplastics battery box by placing the mating parts of each into physical contact with a heater to soften the mating parts and then pressing the lid and box together. The pack of battery plates may be preformed or may upon assembly into the compartments carry a suitable paste for conversion to the respective positive or negative plate material. This conversion may be carried out after the intercell connections have been completed by filling the compartments with dilute sulphuric acid of 1À050 s.g. and connecting to a D.C. supply. Whereafter the dilute sulphuric acid is removed and replaced by conventional battery acid of 1À25-1À28 s.g. Alternatively if an acid of 1À255 s.g. is used for the conversion it may be retained in the cell as the final electrolyte as it then has a resultant specific gravity of 1À28. As shown in Fig. 3 the heater 25 used to soften the internal peripheral shoulder 23 and the transverse ribs 24 of the thermoplastics lid 21 is undercut away from its surface of physical contact to ensure that the peripheral depending wall 22 of the lid is not heated.
Patent GB-740591-A (GB)
Title: N-carbamylimides
Filed: 1953-09-20
Abstract: N-carbamyl amic esters derived from a olefinic dicarboxylic acids having 4-6 carbon atoms and having two carbon atoms between the carboxylic groups, can be copolymerized with monomers containing a terminal vinyl group CH2=C<, such as styrene. Typical esters are those of N-carbamyl maleamic acid.  Many others are mentioned; the carbamyl group may be substituted by hydrocarbon radicals.ALSO:The invention comprises N-carbamyl-imides of a -olefinic dicarboxylic acids having 4-6 carbon atoms and having two carbon atoms between the carboxylic groups, the N-carbamyl substituent being of the formula-CO-NH-A, where A is hydrogen or a hydrocarbon radical.  These are made by dehydration of the corresponding N-carbamyl amic acids by treatment with the anhydride of a saturated aliphatic monocarboxylic acid having 2-4 carbon atoms (e.g. acetic anhydride).  By heating the products, with or without a catalyst (e.g. zinc chloride) or a solvent, the carbamyl group is split off (as iso-cyanic acid or ester thereof) leaving the unsubstituted imides.  The N-carbamyl-imides also react with non-tertiary alcohols to give N-carbamyl amic esters useful for making copolymers.  The starting materials are made as in Specification 727,867.  Examples show the preparation of N-carbamyl-maleimide, N - carbamyl - itaconimide, N - carbamylcitraconimide, N - (n - butylcarbamyl) - maleimide, N - (phenylcarbamyl) - maleimide and N - (t - butylcarbamyl) - maleimide. By decomposition of the above there are obtained maleimide, itaconimide, citraconimide, cyanuric acid (by polymerization of the isocyanic acid formed), phenyl isocyanate and t-butyl isocyanate. Imides may also be formed from ethylmaleic, ethylidenesuccinic, b  - methyl - itaconic and dimethylmaleic acids.  The substituent A may also be methyl, ethyl, propyl, isopropyl, isobutyl, sec.-butyl, amyl, hexyl, heptyl, octyl, nonyl, dodecyl, octadecyl, allyl, methallyl, crotyl, cyclohexyl, bornyl, benzyl, phenethyl, tolyl or naphthyl.ALSO:Cyanuric acid is obtained by thermal decomposition of N-carbamyl-imides of a -olefinic dicarboxylic acids having 4-6 carbon atoms and having two carbon atoms between the carboxylic groups; the isocyanic acid formed initially immediately polymerises to cyanuric acid.  When the N-carbamyl-imide is heated in the absence of a solvent part of the isocyanic acid distils over and forms cyanuric acid in the receiver; the remainder polymerises in the reaction mix and leaves behind cyanuric acid when the dicarboxylic imide formed simultaneously is distilled off in vacuo.  Alternatively the N-carbamylimide may be heated in a solvent in which case the cyanuric acid precipitates and is filtered off.  Suitable N-carbamyl-imides are those of maleic, itaconic and citraconic acids.
