Title: Improvements relating to servo mechanisms
Inventor: SPENCER ROLF EDMUND
IPC: G08C19/46
Filed: 1956-06-16
Abstract: 863,114. Electric automatic machine control systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. June 4, 1957 [June 16, 1956], No. 18720/56. Classes 38 (6) and 40 (1). To maintain constant sensitivity in a servo system comprising a resolver 1 (Fig. 2) whose perpendicular stator windings 3, 4 are fed with dx dy - and - signals, respectively, to induce in rotor dt dt winding 5 a voltage which is automatically eliminated by motor 10, a second rotor winding 12 is added, perpendicular to winding 5, whose induced voltage is shown to be proportional to the loop gain and is therefore used to control the gain of amplifier 11 feeding motor 10. The voltage in 12 is amplified at 13 and compared at 14 with a constant value K, any difference being amplified at 15 to bias the valves in amplifiers 11, 13 to maintain the loop gain at a constant value. In another embodiment (Fig. 3) the loop gain signal in 12 modulates a carrier at 16 which is fed through amplifier 11 together with the signal from winding 5, the modulated gain signal being filtered out at 17 and demodulated at 18 to be compared at 14 with the constant value K to bias amplifier 11 and keep the loop gain constant. In alternative arrangements the signals from windings 5, 12 are multiplexed through amplifier 11, or amplifiers 11, 13 are gated to give an on-off ratio dependent on the output from amplifier 15. The invention is applied to a system for the automatic control of machine-tools from a recorded programme, wherein automatic compensation for the radius of the cutting tool is obtained by feeding a signal representing the radius into a rotor winding 6 and rotating it to an angular position representing the cutting angle at the point of cutting, whereby the signals in associated stator windings 7, 8 are the correction components to be added to the co-ordinate signals controlling the relative position of tool and workpiece. Specification 830,461 is referred to.

Title: Process for producing high bulk yarn
IPC: D02G1/02
Filed: 1972-04-24
Abstract: 1393712 Crimped and bonded yarns TORAY INDUSTRIES INC 24 April 1972 [17 June 1971] 18948/72 Headings D1F and D1W High bulk yarn is produced by false-twisting a single or doubled fibrous strand which contains (in one or more component ends) at least some short fibres e.g. spun staple, and is formed from fibres of different kinds and having different melting points, and heating the strand at such a temperature that the fibres of higher melting point are bonded together at random points throughout the strand by the fibres of lower melting point. The heating is effected whilst the strand is being false-twisted and in such manner that the strand does not come into direct contact with any heated surface e.g. by passage through a hollow heater or tunnel of circular, elliptical or rectangular cross-section, and the strand is maintained in vibration. The strand is underfed e.g. with feed ratio of 0.88-1.00, into the false-twisting zone and the number of false-twists imparted is 50-150 times the square root of the metric count of the yarn produced. The low melting point fibres may be selectively removed e.g. from a fabric made from the yarn, with a solvent. Polyester, polyamide, polypropylene, rayon, acetate, silk and wool fibres may be used in combination. The strand vibration may be that imparted by its ballooning under the action of the false-twisting spindle, friction or pneumatic vortex twister or a vibrator mechanism positioned adjacent the heater inlet or outlet.

Title: Improvements in or relating to steam generators

Filed: 1936-07-09
Abstract: 460,869. Regulating fuel supply to steam boiler furnaces. SIEMENSSCHUCKERTWERKE AKT.-GES. July 9, 1936, Nos. 19074 and 19075. Convention dates, July 18, 1935 and July 8, 1936. [Class 51 (i)] [Also in Group XIII] The ratio of the feed supply to the fuel supply of a once - through boiler is so regulated by changes of water level in a drum 14, which receives under normal conditions dry saturated steam from the generating sections 7, 11, as to bring the level back to normal. The feed valve 26 is controlled by a float 25 in the drum and by a device 24 operated by pressure varying in accordance with the quantity of steam flowing from the drum. If superheated steam enters the drum from the generating sections, the water level in the drum falls and the flow of steam from the drum increases; both the float and the pressure device then tend to open the feed valve. Conversely, if wet steam enters the drum, the feed valve is closed to a certain extent. The fuel supply is controlled by the pressure in the steam delivery pipe 23. The fuel supply may be controlled by the water level in the drum and the quantity of steam flowing from the drum, and the water supply by the pressure in the steam delivery pipe. In a modification, the steam enters the drum through a pipe coil arranged in the water space and opening into the steam space, and part of the steam may flow directly from the generating sections to the superheating sections under the control of a valve operated in dependence upon the difference of pressure at the inlet and outlet of the drum.

Title: Improvements in or relating to crepe and other highly twisted yarns and fabrics containing such yarns
IPC: D02G3/24
Filed: 1936-07-13
Abstract: 478,207. Yarns. WYLDE, J. R., and FINLAYSON, D. July 13, 1936, No. 19410. [Class 120 (iii)] A crape or other highly - twisted yarn is formed by doubling at least two components, one of low twist and the other of high twist, the doubling twist being substantially the same as the twist in the highly-twisted component but in the reverse direction; the initially low twisted component is thus given a high degree of twist and the initially highly-twisted component is substantially freed from twist and is doubled to a high degree with the initially low twisted component and lies somewhat loosely outside the composite yarn. The twist in the highly-twisted component may be a crape or voile twist; the components may be continuous filament yarns or fibrous yarns or may comprise both kinds of yarns; they may comprise the same or different materials e.g. a low twist cellulose acetate component may be doubled with a high twist viscose component; and the components may be of different appearance e.g. of different colour or lustre. When the yarn contains a low twist component of an organic derivative of cellulose e.g. cellulose acetate. the final doubling is advantageously effected while the yarn is under the influence of steam or hot water as described in Specifications 437,019, 438,590, and 438,591.
