Patent GB-1152771-A (GB)
Title: Hydraeric Control System
IPC: F15B13/04
Filed: 1966-08-16
Abstract: 1,152,771. Fluid-pressure servomotor systems. BELL AEROSPACE CORP. Aug. 16, 1966 [Aug. 23, 1965], No.36583/66. Headine G3P. A fluid control system comprises an active servovalve 41, a stand-by servovalve 51 and a monitor servovalve 61. The valves are similar and comprise a flapper 104, movable in response to an electrical input, to actuate a spool valve 109, a spring 113 providing a feedback. The position of the spool 109 moves a flapper 115 to provide a fluid signal proportional to the spool position. The spool positions are compared in pairs by comparators 71, 72, 73 each of which comprises a valve spool loaded to the central position by springs and subjected at opposite ends to the pressures from two flappers. Each comparator controls a pressure release valve 132, 142, 152 which normally connects conduits 76, 77, 78 to a pressure supply but closes the connection to supply when the comparators connect these conduits to drain. The conduits 76, 77 are connected to chambers of switching valves 135, 136 and the conduit 78 to an actuating chamber 219 of switching valve 136. The various valves and actuator chambers are connected to the pressure supplies P 1 , P 2 , P 3  in the manner indicated, these supplies being those to the servovalves 41, 51, 61. In operation an input signal is fed to the servovalve and if the system is functioning normally the valves are in the position shown in which spool 109 of the active servovalve 41 controls the movements of the actuator 47. If the servovalve 41 fails, comparators 71, and 72 are subjected to a pressure differential which causes the conduits 76, 77 to be connected to the reservoir R 1  and the valves 132, 142 close. The fall of pressure in conduits 77, 76 also cause the switching valve 135 to move to the right to connect the actuator conduits to reservoir and also close the conduits from spool 109 of servovalve 41 while the switching valve 136 also moves to the right whereby the actuator 47 is controlled by the spool of stand-by servovalve 51. The Specification also describes an arrangement of two monitor servovalves where only two separate pressure supplies are necessary.

Title: Improvements in or relating to the treatment of keratinic textile fibres to improve their resistance to felting
IPC: D06M13/364
Filed: 1964-09-09
Abstract: Keratinic textile fibres, e.g. wool, are given improved resistance to setting and may be bleached, by treating them with a solution containing an alkali metal salt of N-dichloroisocyanuric acid and an alkali metal permanganate and having a pH of 6.5-9.  The pH of the solution may be adjusted by the addition of alkali.  The concentration of N-dichloroisocyanuric acid salt in the solution is preferably such that the active chlorine content of the solution is 1-5% by weight of the fibres being treated and the concentration of alkali metal permanganate, e.g. potassium permanganate, may be 0.5-2.5% by weight of the fibres being treated.  The weight ratio of textile materials treated to processing bath is preferably in the range 1:5 to 1:60 and the treatment may be carried out for 20-90 minutes at 5-35 DEG C.  The treating solution may also contain an anionic, cationic or non-ionic surface active agent, e.g. a condensate of ethylene oxide with lauryl alcohol.  The fibres may subsequently be dechlorinated by treatment with an aqueous solution containing sodium bisulphite or hydrosulphite.  The fibres may be in the form of wadding, combed or carded ribbon, thread, woven or knitted fabric or made-up articles.

Title: A method and apparatus for calibrating a gauge
Inventor: FLEMING JOHN WILLIAM JR
IPC: D21G9/00
Filed: 1967-12-12
Abstract: 1,215,948. Gauge calibration. INDUSTRIAL NUCLEONICS CORP. Dec. 12, 1967 [Dec. 14, 1966J, No.37670/70. Divided out of 1, 215, 947. Headings G1A and G1S. A method of calibrating a gauge, e.g. a #-radiation gauge 42 for measuring basis weight or a moisture gauge 44 of the capacitance type, which monitors a property of a web 11, the gauge providing measurements of the property of a portion 62 of the web as the web travels along apredetermined path in the direction of its length, comprises cutting a sample from the portion 62 being measured whilst the web is moving, accurately measuring the property of the cut sample, comparing the property measurement obtained with that provided by the gauge on measuring the property of the portion from which the sample was cut, and then adjusting the gauge so as to reduce any differences between the two measurements. In the apparatus described for performing the method the cutter housing 40 is mounted on the same carriage as the gauges 42, 44 and may be moved transversely of the web 11 on rails 61 by motor 60. The gauges transmit signals to a recorder 50 including marking pens 52, 54.producing traces on a chart 55. A master programmer 56 determines the position of the gauges relative to the web. When it is desired to cut a sample a turner 64 generates a voltage pulse to energize a cutter actuator 66 which causes the cutter to enter the web and begin to cut a sample along lines 37. The cut sample is deflected by a tongue into a storage bag. The tuner 64 then removes the voltage pulse and the cutter withdraws from the web to end the sample. An R-C differentiator 70 may be employed to pulse the pen 52 or 54 as the cutter is energized and de-energized to indicate the part of the trace corresponding to the sample cut. Alternatively the pen corresponding to the gauge not being checked may be clamped to indicate the required part of the other trace. After the sample has been cut it is sealed in the storage bag and transported to a laboratory where the accurate measurement is made.

The latter are controlled by a solid state timer and are of pneumatic piston and cylinder type having shock pads (156, 160, Fig. 3, not shown) to limit displacement of the respective actuator rods 90, 100, 120. The assembly is charged with fluent material, e.g. oil, grease, epoxy, adhesives or moulding compounds, from a container (74, Fig. 1, not shown) via port 72 by displacing piston 78 rightwards until annular groove 80 aligns with ports 58, 60 in a surrounding bushing, piston 108 remaining in the closed position shown. Piston 78 is then returned to its closed position and piston 108 moved rightwards to its open position (Fig. 7). Piston 94 is then moved rightwards to force the material through nozzle 76, the volume dispensed depending on the setting of stop bolt 132. Piston 94 then moves leftwards to draw back a small amount of material and prevent drool from nozzle 76. Piston 108 subsequently returns to the closed position to complete the cycle. The housing 12 may be heated when low viscosity materials are used.
