Title: Fabrics
Inventor: MANOCK GEOFFREY WINDLE
IPC: D06C7/02
Filed: 1962-11-30
Abstract: 983,968. Woven stretch fabrics; finishing fabrics. IMPERIAL CHEMICAL INDUSTRIES Ltd. Nov. 21, 1963 [Nov. 30,1962], No. 45345/62. Headings D1K and D1S. Woven fabric has 10-30% stretch imparted to it in one direction by stretching it in the other direction to straighten the yarns, thereby increasing the crimp of the yarns in the first direction; the fabric is heat-set and cooled before removing the stretching force. The yarns whose crimp is increased comprise synthetic thermoplastic fibres having a glass-to-rubber transition temperature above 80C. when wet, for example polyethylene terephthalate or a copolymer thereof with up to 10% of another polyester, or acrylonitrile or a copolymer thereof with up to 20% of another polymer. Weftwise stretch may be produced by treating the fabric on a Bates cylinder-type setting machine, Fig. 5, provided with additional tensioning bars 11-15 of square section, the tension applied to the fabric 10 being adjustable by swinging the bars 12,13 about an axis 16 by means of a handwheel 17; the fabric then passes over feed rolls 18, 19 and a spreader roll 20 to heated cylinders 21, 22 against which it is pressed by aprons 29, 30; it is then cooled by room temperature air supplied by a blower 33 and wound up on a roll 34. Alternatively, weftwise stretch may be imparted in a stenter, into which the fabric is fed under warpwise tension, the fabric being heated and cooled before allowing it to relax. Warpwise stretch can be imparted by treatment in a pin stenter with high weftwise tension, the fabric being taken in with overfeed just short of the amount that would cause waviness of the selvedges. A fabric may be given a crease-resisting treatment at a first temperature at least 30C. below the melting point, followed by one of the above stretch-imparting treatments at a second temperature at least 60C. below the melting point; the first and second temperatures may be equal. A durable pleat can be subsequently inserted in a garment made from the fabric at a third, lower, temperature on a Hoffman press.

Abstract: 1,122,353. Control of stepping motors. BAUSCH & LOMB Inc. 13 Oct., 1966 [15 Feb., 1966], No. 45847/66. Heading H2J. [Also in Divisions G1 and H3] A control circuit for a motor 11 which advances the chart of a chart recorder (see Division G1) a predetermined distance along the X axis of the chart includes an X resolution generator for determining which of four different increments the chart is to be advanced. The X resolution generator comprises four multivibrators connected so that four successive pulses are generated, the position of a switch SW2 determining the number of these pulses which are to be used to drive the motor one, two, three or four increments. The first multivibrator is triggered by a signal from a force plot delay circuit, Fig. 2B (not shown) and is timed at ten milliseconds but its output is differentiated to a one millisecond pulse by C71 and R209 and applied to a diode matrix. The trailing edge of the first multivibrator signal is differentiated by C66 and R191 and triggers the second multivibrator timed at eight milliseconds. The output of the second multivibrator is differentiated and applied to the diode matrix. Thus the time between successive pulses applied to the diode matrix decreases with delays of ten, eight, six and four milliseconds between successive one millisecond pulses. This decreases the time of advance of the chart when it is to be advanced more than one increment and the setting of the selector switchSW2 determines the amount in response to an advance pulse that the chart is to be advanced along the X axis. The output pulse or pulses are amplified by a transistor Q82 and fed to a sequencer circuit. The sequencer circuit comprises two flip flop multivibrators and delivers an orderly sequence of signals to the motor 11 to excite the proper windings. The outputs of the four transistors Q84-Q87 are connected to power drive transistors Q88-Q91 in the chart drive amplifier and the outputs of Q88, Q91 energize the windings of the motor which is a two hundred pole stepping motor.

Abstract: 1,122,031. Photo-electric measurements. NATIONAL RESEARCH DEVELOPMENT CORP. Nov. 11, 1965 [Nov. 11, 1964], No. 46057/64. Heading G1A. The transmissive and reflective properties of a test sample in comparison with a reference sample are determined by alternately moving the test and reference samples into and out of a single light beam between a single source and detector and a measurement value is derived either by bringing to equality the test and reference electrical signals produced by the detector during the test and reference phases or by measuring the ratio of these electrical signals. The signals may be brought to equality either by attenuating them directly or by reducing the intensity of the light beam whilst either the test or reference sample is illuminated with a variable aperture shutter or a variable time of opening shutter. The final electrical measurement-valve signal may operate a recorder or control an industrial process. The samples may be mounted on a wheel or reciprocating slide whose movements may be continuous, or step-wise to momentarily hold the samples stationary in the beam. The wavelength of the light may be varied by using a variable output monochromator or filters. Fig. 10 shows a unified optical arrangement for determining direct, diffuse or total transmissive and reflective properties and also luminance factors. It comprises two integrating spheres IS1, IS2, two wheels W1, W2 for supporting the reference and test samples RS, TS, of which liquids are mentioned, and four photo-cells PC1 to PC4 covered by diffusing screens DS1 to DS4. Using the integrating sphere IS1 and wheel W2 the direct reflective factor is determined using PC4, the light paths for which are shown, and the diffuse and total reflective factors determined using PC2 with the cap C (shown dotted in Fig. 10) blocking off PC4 and internally painted either black or white respectively. The equivalent transmission factors are determined using integrating sphere IS1, photo-cells PC1 and PC3 and wheel W2, but with wheel W1 and integrating sphere IS2 removed. The luminance factor, for which light is directed at 45 degrees on to the sample which is then viewed in a normal direction, is determined using wheel W1 and photo-cell PC4 with wheel W2 and integrating sphere IS2 removed; a prism placed after lens CL directs light away from prism PC2 and at 45 degrees to the right hand side of the wheel W1 as viewed in Fig. 10. The inverse luminance factor, which is vice-versa of the above luminance factor, uses wheel W1 and photo-cell PC4, the prism PC2 now directing light normally on to the sample and PC4 receives light reflected at 45 degrees.

Title: Indicating instruments

Filed: 1961-12-29
Abstract: 1,006,096. Aircraft instruments. SPERRY RAND CORPORATION. Dec. 29, 1961 [Jan. 10, 1961], No. 46700/61. Heading B7W. Apparatus indicating the value of an aircraft flight parameter includes an instrument housing having a pointer and a reference member, movable along the same or adjacent paths relative to an index or indicia, the two movable members being controlled so that the displacement between them indicates the value of a signal representing the parameter, the displacement of the pointer and the reference member indicating the value of the shortterm and long-term components of the parameter. In Fig. 1, a fixed part 34 of the indicator bears a fixed index (not shown), and rotatably supports a ring 32 marked with a heading scale which co-operates with a pointer 36. A heading signal is fed to a comparison circuit 10 energizing a slow response servo 16, e.g. a servo damped by a rate feed back signal, which drives ring 32 and a synchro 20, the latter providing a feed-back signal to circuit 10. The position of ring 32, and the signal from synchro 20, thus represent the long-term value of the heading signal. The output signal from circuit 10 is therefore the short-term component of the heading signal, and this is fed to a comparison circuit 14 energizing a quick response servo 22 driving pointer 36 and a feed-back synchro 26. The displacement between the ring and pointer thus always represents the heading. A rapid change of heading is indicated by immediate displacement of pointer 36 to indicate the instantaneous heading on ring 32, and the pilot can observe such changes by concentrating on the pointer. A long-term change of heading results in rotation of ring 32, and the new steady heading is shown on ring 32 against the fixed index. During a steady turn, the output of circuit 10 tends to a constant value indicative of the rate of turn, whereby pointer 36 can be used as a rate of turn indicator, and an appropriate scale may be marked on the instrument. A ball bank indicator may be placed on the instrument face. Provision is made so that if either servo fails, the other can be made to operate its associated member 32 or 36 to indicate the total value of the heading signal. The ring 32 may be rotatable manually and locked showing any desired heading against the fixed index. The comparison circuit 10 then has an output representing the heading error, so that pointer 36 is upright when the aircraft is on course. Servo 16 may be disabled by a switch. In an alternative arrangement, the heading signal is divided into long and shortterm components by low and high-pass filters of equal time constant, the two components energizing servos 16 and 22 respectively. Fig. 10a shows a bank indicator, wherein short-term changes of bank result in immediate rotation of an aircraft representation 98. If a new bank angle is held, the representation 98 and a line 97 are rotated eventually to a position in which the representation is horizontal and the line 97 is tilted like a conventional artificial horizon. The parameter displayed may be altitude or airspeed.
