Title: Improved linear polyesters and polyesteramides
IPC: C08G69/44
Filed: 1960-12-19
Abstract: A linear polyester or polyesteramide has at least 5% of residues derived from 2,2,4,4-tetraalkyl-1,3-cyclobutanediol (see U.S.A. Specification 2,926,324), the alkyl groups of which contain 1-4 carbon atoms.  Other ingredients of the polymers are usual ones, e.g. glycols, bisphenols, hydroxy-carboxylic acids, amino-alcohols, diamines, aminocarboxy compounds and dicarboxylic acids or ester- or amide-forming derivatives thereof.  A number of suitable compounds are listed.  Most of the examples employ 2,2,4,4-tetramethylcyclobutane-1,3-diol.  Sometimes a pure isomer is used and sometimes a mixture of cis- and trans-isomers. Polymers are prepared, using as the co-ingredients: (1), (2) diphenyl-trans-cyclohexane-1,4-dicarboxylate, with lithium hydride and calcium hydride as catalysts; (3) diphenyl isophthalate; (4) diphenyl terephthalate with lithium hydride and magnesium as catalysts; (6) diphenyl carbonate with lithium hydride as catalyst; (7) dibutyl carbonate, with sodium butoxide as catalyst; (8) diphenyl terephthalate with lithium as catalyst; (9) diphenyl terephthalate; (10) diphenyl terephthalate and diphenyl carbonate with lithium as catalyst; (11) diphenyl terephthalate and diphenyl azelate; (12) diphenyl terephthalate and diphenyl isophthalate; (13) diphenyl terephthalate and 1,4-cyclohexanedimethanol (70% trans, 30% cis isomers); (14) dimethylene terephthalate hexamethylene diamine and dimethyl terephthalate; (15), (16) terephthalic acid and bisphenol A. In Ex. (5) 2,2,4,4-tetraethylcyclobutane-1,3-diol is employed together with diphenyl terephthalate.  It is also stated that a polyester-amide can be prepared from diethyl isophthalate, benzidine, and 2,2,4,4-tetra-alkyl-1,3-cyclobutanediol.  The products have high melting points, e.g. 100 DEG -375 DEG C. and are useful for forming fibres or films, e.g. for photographic uses, or other moulded articles.

Title: Gating circuits for low level signals
IPC: H03K17/62
Filed: 1962-11-20
Abstract: 1,027,472. Transistor gating circuits. WESTERN ELECTRIC CO. Inc. Nov. 20, 1962 [Nov. 29, 1961], No. 43786/62. Heading H3T. A gating circuit comprises an amplifier and an impedance which produce equal and oppositely phased signals which cancel to produce a zero output, and means operable by a gating signal to modify the gain of the amplifier without changing its D.C. bias conditions so that the output from the amplifier is greater than that from the impedance. As described, a number of similar gates each comprises an amplifier Q1 the gain of which is adjusted by an A.C. feedback path comprising resistor R1, to produce at its collector an output which cancels that produced via resistor RF, so that inputs signals EG1 . . . EG3 are prevented from reaching the output EO. In order to pass one of these signals to the output, the feedback path of the associated amplifier is shorted by switching on a transistor Q2 so that the gain of the amplifier increases, and its output is no longer balanced by the signal via resistor RF.

Title: Improvements in the treatment of woollen fabrics
IPC: D03D15/56
Filed: 1961-12-07
Abstract: 949, 883. Treating woollen fabrics. J.P. STEVENS & CO. Inc. Dec. 7, 1961 [Dec.12, 1960], No. 43859/61. Headings D1K, D1L and D1P A woven fabric comprising a set of weft yarns and a set of warp yarns of which one of the sets comprises wool and is preferably of woollen yarns which have been highly twisted, is treated at an elevated temperature with a solution of a stabilizing agent capable of setting the yarns to cause shrinkage of the yarns, treated to permanently set the yarns in their contracted state and is then dried by the application of heat while it is in a loose, tensionless state, to produce a fabric in which the wool is in a highly crimped and bulked state and which is capable of stretching by at least 8% and of returning to its contracted state when the stretch force is released. The stabilizing agent may be monoethanolamine sulphite, thioglycolic acid or its calcium or sodium salts, sodium formaldehyde sulphoxylate, sodium bisulphite or sodium borate and the treating solution may also contain a sequestering agent, e.g. a non-toxic alkylarylpolyether. The fabric may be treated with the solution of the stabilizing agent at 212-230 F. under a pressure adapted to prevent the liquid from boiling and may be cooled by the passage of cold water therethrough to a temperature to arrest the action of the stabilizing agent prior to drying. The fabric which may comprise textured yarns, e.g. crepes, boucles, slub and flake yarns, may subsequently be treated with an aqueous solution of hexamethylene diamine and a solution of sebacyl chloride in trichlorethylene or perchlorethylene to deposit a coating of nylon on the fibres. As shown in Fig. 1 the fabric 9 in a wet or dry state may be rolled loosely on drum 11 having perforations 12, covered with a fabric sleeve 13 and placed in treating vessel 20 containing the solution of the stabilizing agent admitted from reservoir 41 and recirculated by pump 30 driven by motor 31, and heated in heat exchanger 35 provided with steam pipes 36 for supplying steam at elevated pressures. After treatment with the stabilizing agent the package is removed from the vessel 20, unrolled on a pair of supporting rollers 51 shown in Fig. 2, passed between a pair of squeeze rolls 52 to reduce its liquid content to a predetermined value to scray 54 and slack loop dryer 55 supplied with hot air from pipe 56 where it is free to shrink. Alternatively after treatment with the solution of the stabilizing agent the fabric may be squeezed and wound with a fabric apron on a decatising machine as shown in Fig. 3 comprising a drum 60 having perforations 61 on which the wet treated fabric 62 is rolled from a supply roll 63 with an interleaved fabric apron 64 delivered from supply roll 65 and heated by steam supplied to the interior of the drum and then through the perforations 61 for 3-5 minutes. The fabric may then be cooled by passing cold water therethrough, removed from the decatising machine and dried in a slack loop drier.

Abstract: 441,028. Reproducing lenticular picture films. OPTICOLOR AKT. - GES., Glarus, Switzerland. Sept. 14, 1934, No. 26453. Convention date, Sept. 15, 1933. Addition to 421,084 and 435,859. [Class 98 (ii)] In apparatus for copying lenticular films by projection according to the parent Specifications the plane reflecting surfaces are arranged to rotate about an axis. The moving parts may be rigidly mounted on a rotating holder or some parts, e.g. the objective, may remain stationary with respect to the films. In one form, plane mirrors 4, 5, Fig. 6, are arranged parallel to one another on opposite sides of the objective 3, on a carrier 6 which revolves about the optical axis. The film 1, illuminated by the source 44 is projected by angle mirror 38, the mirror and objective system 4, 3, 5 and mirror 39 onto the copy film 2. Field lenses 58, 59 may be arranged in front of the films 1, 2. Stray light is cut off by screens 7, 8. In order to interrupt the copying when the image of the objective seen from the films passes over the lines corresponding to the dividing edges of the striped filter used in taking and when the films are advanced one frame, a shutter 43 provided with four blades is placed in front of the objective, and the light source 44 is enclosed in a drum shaped screen 47, the part between the points 48 and 49 being opaque. Since the time of exposure of the parts corresponding to the lateral zones of the filter is longer than that of the part corresponding to the central zone, grey glasses 50, 51 may be inserted in the aperture of the drum to adjust the intensity of the light during the copying of the side zones. Various modified forms employing different arrangements of objective and plane reflectors and a form employing a concave mirror in place of an objective are described. The apparatus may be used for copying on the same or different scales and for copying lenticular films other than colour-record lenticular films, e.g. stereoscopic records.

Abstract: 966, 047. Automatic control of speed. LOUIS ALLIS CO. Dec. 13, 1961 [Dec. 13, 1960], No. 44608/61. Heading G3R. [Also in Division H2] A Ward-Leonard control system, having automatic cross-over from armature voltage control to field-energization control, comprises a generator 14 driven by a three phase motor 20, connected by conductors 22, 23 to a motor 17 driving a shaft 24. The motor field winding 18 is energized from an amplifier 26 and the generator field winding 16 from an amplifier 30. The motor speed is set by movement of a slider 42 of a potentiometer 34 the output voltage e r  of which is fed to a function multiplier 54 to which is also fed a signal e fa  from the output of the amplifier 26 through a resistor 56. The output of the multiplier is em = Ker . e fa  and is fed to the input of the amplifier 30 and to a diode 60. At low speeds the field winding 18 is energized at a constant voltage, determined by reference voltage E at the input to the amplifier 26 through a resistor 56 and stabilized by negative feed-back through a resistor 48 and a diode 50. The input e fa  to the multiplier 54 is then constant and the voltage e m  applied to the input of the amplifier 30 is proportional to e r  and the speed of motor 17 is controlled by variation in armature voltage, which is stabilized by negative feedback through a resistor 66 and IR compensated through an impedance 68 and a shunt 67. At high speeds voltage e m  exceeds voltage E and diode 60 conducts so that with an increase in the voltage e r  the voltage across the field winding 18 is progressively decreased to increased motor speed. Reduction in the field voltage causes the voltage e fa  to fall so that the multiplier output voltage e m  is maintained at that value at which the diode 60 becomes conductive. The voltage em being constant the energization of the field winding 16 is kept constant and the speed of the motor 17 is varied by field-weakening in dependence on the setting of the slider 42. The amplifiers may be electronic, magnetic or rotating amplidyne or metadyne amplifiers.

Abstract: 1439936 Steam power plant UNITED KINGDOM ATOMIC ENERGY AUTHORITY 24 Sept 1973 45494/72 Heading F4A In a steam power plant in which a boiler 2 supplies steam to a turbine 3 driving an alternator (not shown) a controller 15b operates a steam by-pass valve 15 in response to a sensed part load condition to divert steam via a jet pump 18 to a feed water storage drum 17. Valve 15 is linked to turbine governor valve 4, preferably hydraulically, so that valve 4 opens as valve 15 closes and closes as 15 opens. The controller receives inputs from two transducers: 15c which indicates the steam flow from the boiler (lbs./hr) and 15d which indicates the temperature of water leaving the feed water storage drum 17. The controller maintains steam flow from the boiler constant up to the point at which the feed water leaving 17 is at a pre-set value, after this point the controller responds to the temperature only. As shown condensed steam from the turbine passes back to the boiler via direct contact heaters (not shown) a deaerator 11, a high pressure pump 12, and high pressure heater 13. A by-pass, controlled by a valve 17 leads from the outlet of jetpump 18 to the deaerator.

A device measuring rate of fuel consumption of a motor vehicle comprises: (a) a tacho-generator 1, Fig. 1, measuring vehicle speed, (b) a flow meter operating an interrupter contact 2, Fig. 2, giving a pulse output of which the frequency is inversely proportional to the time rate of fuel flow, and (c) integrating means which combines the two signals to indicate at 17 the average value of fuel consumption. The interrupter contact 2 is driven by a rotary flowmeter, and successive closures of the switch 2 respectively open and close a relay A, which thus operates at half the frequency of the interrupter 2. One contact a1, of the relay connects the tacho 1 signal to the base of a transistor 3, the output pulses of which vary in height with vehicle speed and inversely in width with rate of flow. The remaining contacts a2, a3, a4, of the relay A control the operation of a multivibrator consisting of relays B, C and a capacitor 12. The periods during which relays A and B are energized vary with variations in the flow rate. Certain of the contacts of relays B and C are connected so that the tacho signal pulses from transistor 3 charge a condenser 8 and a condenser 9 alternatively. While one condenser is being discharged and recharged, the other has its voltage measured by a voltmeter circuit comprising transistors 13, 14 and a meter 17. Contacts c3, c4 and b2 control the measuring and charging processes, and contacts c5, b3 and b4 control the discharging process. The remainder of the contacts of the relays B, C, are connected in the multi-vibrator circuit.
