Title: Improvements in the treatment of cellulosic textile materials
IPC: D06M15/423
Filed: 1961-04-27
Abstract: Cellulosic filamentary material, i.e. filament yarns, threads and woven, knitted or non-woven fabrics, are impregnated with a heat-hardenable resin precondensate made by reacting urea with an epihalohydrin to form a urea: epihalohydrin adduct and reacting the adduct with formaldehyde or para formaldehyde and optionally further reacting with an aliphatic alcohol having 1-6 carbon atoms, converted to a more complex textile form i.e. raw fibre is converted to yarn, yarn to fabric and fabric to garments or other fabric structure and the resin precondensate then cured.  The precondensate may be applied to the filamentary material as an aqueous solution containing 2.5-18 by weight of precondensate, an acid or acid forming cross-linking catalyst, e.g. acetic, phosphoric and hydrochloric acids, organic amine halides such as propanol amine hydrochloride, metal halides such as zinc and magnesium chlorides, metal sulphates such as magnesium sulphate and metal nitrates such as zinc nitrate, and conventional finishing agents such as hand-builders, lubricants and water repellants, e.g. silicone emulsions, polyethylene emulsions, hydroxyethyl cellulose and polyethylene glycol stearate.  The filamentary material may then be dried at 60 DEG -150 DEG C. and converted into a more complex form if desired after storage at 10 DEG -40 DEG C. Fabric segments may be joined to form fabric structures with an internal adhesive e.g. two fabric segment containing cellulose acetate fibre may be joined by heat and pressure sufficient to cause plasticization and coalescence of the cellulose acetate, or with an external adhesive, e.g. a latex cement or by sewing with a thread or yarn which is itself impregnated with the precondensate and fabrics and garments may be creased, pleated or emboss prior to curing.  The more complex textile structure may be moistened by spraying with water or steaming to raise its moisture content from 20-40% by weight and pressed and cured by using a "hot head" press at 150 DEG -180 DEG C. or pressed and then cured by hanging in a curing oven at 150 DEG -180 DEG C. for 3-20 minutes.  Yarns having permanently set twist suitable for making carpets and other pile fabrics may be made by impregnating fibre with the precondensate, drying, spinning into yarn having a high degree of twist and curing before or after making into a pile structure.  Natural cellulose fibres, e.g. cotton and linen, regenerated cellulose fibres and cellulose derivative fibres e.g. cellulose acetate, propionate and butyrate and carboxy methyl and carboxy ethyl cellulose, having not less than 1.5 unreacted hydroxyl groups per anhydro-glucose unit, alone or in admixture with other fibres, e.g. nylon, polyester and acrylic fibres, in which the proportion of cellulose fibres is at least 50% by weight may be treated. Specifications 796,815, 951,543 and 951,544 are referred to.

Title: Voltage control apparatus
IPC: G05F1/20
Filed: 1976-04-08
Abstract: 1500444 Automatic voltage and current control FERRANTI Ltd 8 April 1976 [15 April 1975] 15592/75 Heading G3R A voltage regulating circuit has two AC inputs of the same frequency and phase, but different voltages. A control device responds to changes in the output voltage of the circuit to replace the lower input voltage by the higher input voltage over a part of each AC cycle. As shown in Fig. 4, a transformer 10 provides a rectified output voltage on lines 12, 13. Line 12 is connected directly to a centre tap, while line 13 can receive a low voltage from intermediate taps through diodes D1, D2 or a high voltage through thyristors TH 1, TH2 connected to the ends of the transformer secondary winding. The thyristors are turned on at times during the supply cycle determined by a control signal on line 14, and operation is synchronized with the AC input by a transistor T3 which produces negative pulses at zero crossings. The signal on line 14 is produced by a control circuit, Fig. 6 (not shown), including a monostable device (M) responsive to the output of an operational amplifier (A2) which compares the circuit output voltage with a reference voltage derived from a Zener diode. A conventional series regulating circuit, Fig. 5 (not shown), is connected between the transformer outpout line 12 and the circuit output terminal, and includes a series transistor (T4) controlled by a regulating module (VR) in dependence on measured output current and voltage. In other embodiments, Figs. 7 and 8 (not shown), the secondary side of the transformer 10 is connected through a single-phase or three-phase rectifier bridge circuit.

Title: Improvements in or relating to automatic or semi-automatic or like telephone exchange systems and apparatus
IPC: H04Q3/42
Filed: 1932-06-02
Abstract: 402,452. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., WRIGHT, E. P. G., HARTLEY, G. C., and FIELDING, E. C., Cught House, Aldwych, London. June 2, 1932, No. 15638. [Class 40 (iv).] In a system employing single-motion conversational switches having a double set of wipers arranged 180‹ apart so as to engage corresponding terminal rows in turn and controlled by by-path marking switches, the final selectors have two sets of such wipers, thus giving access to 200 lines, and wiper-switching is controlled by a discriminating signal from a previous selecting stage. In Fig. 1, each group of outlets from the penultimate bypath switch PR2 is common to a pair. of consecutive odd and even hundreds digits, and if the digit is odd, relay JA energizes over the switch PR1 which receives the digit and sends forward a signal to operate the wiper-switching relay FKS in the final selector, which is set in accordance with the tens and units digits by marking from the switch FR2. In Fig. 2, the merging takes place at the thousands stage, and relay JA controls relay FKS over the by-path switches IR2, PR2. The by-path switches have two sets of wipers, and in order that the sizes of the groups may be varied, each group is wired exclusively to one bank of the switch PR2, and a relay C (not shown) is provided to prevent overrunning where necessary ; for example, the starting position of group 4 in one bank may be earlier than that of. group 3 in the other bank, and if the digit is 3, the switch waits in the earlier position until relay C relapses. In Fig. 3, merging takes place at both the thousands and hundreds stages. Relay JA is dependent on the odd or even value of the thousands digit and controls the marking of different groups in the hundreds by-path switch PR2, while relay JB controls relay FKS according as the hundreds digit is odd or even. An alternative arrangement is shown in Fig. 4, in which each group is wired exclusively to one bank of the switch PR2, and relay JA controls wiper-switching at the switch PR2 and connects up one of two marking banks of the switch PR1. Normally 25 final selectors are available for grading over a group of 10 outlets from the penultimate stage, but in some groups the full number of final selectors may be unnecessary. Fig. 5A shows the grading of two groups of 25 and 20 final selectors respectively over 6 penultimate switches. If it is desired to increase the availability of final selectors of the left-hand group, the arrangement of Fig. 5B may be adopted, two outlets being transferred from the right-hand to the left-hand group, and the full number of 25 final selectors being graded over the 8 outlets of the right-hand group.

Counter-clockwise rotation of shaft 69, further to extend the leg rest, is permitted by ratchet action of pin 143 and notches 139. In the fully extended position of the leg-rest, tooth 137 transfers pins 143 to the uper leg of L-shaped slot 141. In this position it is carried above notches 139, so that the subsequent retraction of the leg rest to the folded position is unimpeded. Tooth 135 is operative, in the folded position, to return the pin 139 to the lower leg of slot 141 so as to re-institute the ratchet action. The leg rest 43 is fitted to a reclining and platform rocking chair (11).
