Abstract: 957,079. Treating polyamide filaments. IMPERIAL CHEMICAL INDUSTRIES Ltd. Aug. 14, 1962 [Oct. 5, 1961], No. 35894/61. Heading B5B. Melt-spun filaments of a polymer of metaxylylene diamine and adipic acid are drawn at least three times their original length while passing through a heating zone, e.g. a hot pin or roll. The minimum temperature of the heating zone (Tp ‹ C.) satisfies: Tp=109-9.25 M. . . . . . . (1) where M is the % moisture content of the spun yarn to be drawn. The relative humidity (H %) of the environment in which the spun yarn, prior to drawing, is conditioned, does not exceed that defined by: H=118-0.55 T .....(2) where T (‹ F.) is the ambient temperature of the conditioning environment. The drawn filaments may subsequently be passed over a heated plate, the minimum temperature (Tpl ‹ C.) of which satisfies Tpl=172-11.1 M ..... (3) Equations (1) and (3) may be expressed as Tp=109-0.83 H<SP>1</SP>..... (1a) Tpl=172-H<SP>1</SP> ......... (3a) where H<SP>1</SP> is the % relative humidity at 70‹ F. of the atmosphere in which the yarn is stored prior to drawing. The required moisture content M may be obtained by storing the yarn in cabinets at predetermined temperature and relative humidity, or by feeding the yarn directly from the spinning unit into the feed roll system of a drawing device, without contacting the yarn with an aqueous spin finish, M then being zero. The polymer may also contain not more than 10% of para-xylylene diamine.

Abstract: 738,966. Sparking plugs. GENERAL MOTORS CORPORATION. Dec. 28, 1953 [Dec. 29, 1952], No. 35967/53. Class 7(4). [Also in Group XI] A combined fuel injector and igniter device particularly for the combustion system of a gas turbine engine comprises a substantially cylindrical duct adapted to project into the combustion system, a supply pipe to feed fuel to an annular chamber lying around the circumference of the duct, and containing a filter element, a hollow central electrode forming a fuel conduit and comprising an annular chamber containing a second filter element, and passages to conduct fuel from the first filter to and through the second filter to be discharged through the electrode conduit. In the device illustrated the electrode is supported by a member 92, Fig. 1, which is disposed in an insulating sleeve 36 having an outer shoulder resting on a spring washer 32 supported by an inner shoulder of an outer shell 2. A tubular insulator rests on the flared upper end 94 of the member 92 and receives an electric supply cable (not shown) retained by a cap (not shown) threaded on to a surrounding tubular shield 170. Liquid fuel is supplied through an elbow connector 58 maintained by a spring clip 68 so that a resilient outlets nipple 56 thereof is pressed through the wall of the shell 2, and the fuel passes into an annular chamber 210 containing a stainless steel mesh filter 44, and thence through annular spaces 214, 216, four holes 218 in the head 94, and a further fine mesh filter 150 wound around a core 144. The fuel discharges through a bore 226 in the core 144 into a valve chamber 228 to force a valve member 136, Fig. 2, from its seat against the action of a spring 134. The fuel then flows along the flat sides of the member 136 and past the bottom 234 and bores 236, 238, and 240 in a core 132 to pass into chambers 244, 246 from which it discharges through nozzles 128, 130. The discharged fuel impinges on inclined faces of target pins 110, 112 to produce a finely atomized spray which is mixed with air in a venturi 22 and ignited by sparks passing radially extending electrode prongs 196 and the lower end 26 of the venturi. The prongs 196 extend from a stub 118 held by a pin 202 in a holder 108 press fitted into the lower end of the member 92. The venturi end 26 is formed of a metal which stores sufficient heat to retain the flame thereat. When assembled in a gas turbine engine the lower part of the shell 2 extends into a well 12 disposed between the outer casing wall 10 and the flame tube wall 14, and part of the air flowing between the walls 10, 14 passes through apertures 204 in the wall of the well 12, and a part flows through circumferential ports 206 in the shell 2 and the remainder flows through the venturi 22 via ports 208.

Title: Pneumatic gauges
IPC: G01B13/00
Filed: 1956-11-26
Abstract: 842,045. Pneumatic gauge-photo-electric control. TOLIMIT GAUGES Ltd., WILLS, S. A., and GATHERCOLE, E. F. J. Feb. 26, 1958 [Nov. 26, 1956], No. 36152/56. Class 40(3). In a pneumatic gauge the rate of flow of gas through the measuring head is determined by means, including a photo-electric cell, and responsive either to the pressure measured by a monometer at the throat of a venturi placed upstream of the head, or to the position of a plug in a transparent divergent passage through which the air flows and whose vertical displace-. ment is a measure of the gas flow. In Fig. I the gas compressed air flows from a constant pressure source via the venturi 17 to the measuring head 18. The difference in pressure between the Venturi throat 17 and the point 16 upstream thereof is a measure of the gas flow and this difference is measured by the monometer comprising tubes 21 and 18 and the tank 20. In addition to the calibrated scale 19 two photoelectric detectors are provided comprising the lamps 25 and 30 and associated phototransistors 26 and 31 which are energized when there is no liquid between them and the source. The detectors are slideably mounted so that they can be set to any position on the scale 19, the output of each photo-transistor is amplified by a further transistor and operates a relay. In operation the relays associated with each  detector can be arranged to operate visual indicating devices which indicate whether an article being gauged is within required dimension limits, or arranged, in conjunction with a machine tool, to cease a machining operation when the size of the article being machined reaches a required dimension.

Title: Improvements in or relating to indicating apparatus for scoring games or for other purposes
IPC: F41J3/02
Filed: 1938-12-12
Abstract: 522,630. Scoring-apparatus for games ; calculating-apparatus. ELWELL, E. M. Dec. 12, 1938, No. 36179. [Class 132 (ii)] [Also in Group XIX] An indicating apparatus particularly for registering the individual and total scores in games such as darts and billiards comprises a number of units each including a scale of numbers, means associated with the scale for positioning a score-indicating member in relation thereto, and mechanism the movement of which is determined in one direction by the position of the score-indicating member for subsequently actuating a counter for registering the aggregate score. In a form suitable for scoring darts, the apparatus comprises counters 2, 2a for the opposing sides, the counters being provided with trip levers 2b, 2c for setting them to the total score required when commencing the game. When the score of a player is to be subtracted from a counter, a corresponding peg 10 is inserted in the appropriate hole 3d in a series of holes numbered 1 to 100 from the bottom upwards, and a finger piece 11 is moved up to the peg and then returned to zero. The finger piece is secured to an endless strip 5 which drives the counter 2 through a one-way clutch-and thereby makes the subtraction from the previous total. Instead of pegs 10, sliding pointers may be used. The endless bands 5 may be replaced by racks or by slides travelling in arcuate, cylindrical, semi-circular or circular paths. The counters may be arranged for addition instead of subtraction.

Title: Sorting apparatus
IPC: B07C5/344
Filed: 1965-08-24
Abstract: 1,116,722. Determining physical qualities. SPHERE INVESTMENTS Ltd. Aug. 24,1965 [Aug. 26,1964], No. 36207/65. Addition to 1, 009, 597. Heading G1N. In sorting apparatus of the type described in the parent Specification, the spring electrodes 104 are mounted on the opposite side of the path to the trajectory plate 17 and an arc discharge current between one of the spring electrodes and a conductive portion of the trajectory plate or between a conductive portion of the trajectory plate and a flat electrode embedded in a non-conductive part of the trajectory plate is initiated or interrupted by movement of an appropriate body past the electrodes thereby controlling an associated air blast nozzle to direct the body to an appropriate one of two conveyer belts (not shown). The spring electrodes are critically damped and are spaced across the whole width of the path. They may be grouped in pairs, each group controlling one nozzle. The electrodes may be energized with high voltage D. C., A. C. or pulses in which case the duration of the air blast may be controlled in accordance with the number of pulses of the spark discharge or interruption. The medium in which the particles move may be oil or gas instead of air. In the case of discharge being interrupted by the bodies, photo-cell means may be used to initiate discharge on the approach of a body to the electrodes. Photo-cells may also be used to control the air blast nozzles in which case a signal from an electrode may inhibit the blast from an appropriate nozzle.

Title: Improvements in or relating to the manufacture of filter tips for cigarettes
IPC: A24D3/02
Filed: 1933-12-23
Abstract: 432,482. Cigarette-making machines. WIX, A., 338, Goswell Road, and EDWARDS, W. F. M., 2, Kempsford Gardens, Earl's Court, both in London. Dec. 23, 1933, No. 36221. [Class 130] A filter tip is produced by feeding a length of strip material 1 edge first into a receiving chamber 4 in which it is folded upon itself under the influence of the feeding movement. Duplicate feeding means may serve two chambers carried by an oscillating arm and moving alternately from the respective feeding points to a common discharge position 6 at which the filling is delivered transversely into a paper tube. The receiving chambers may be mounted in an intermittently rotatable drum. The width of the strip material is preferably a multiple of the length of filter tip desired. The material after being forwarded by rollers 12, 12a, passes between the slotted guide-rollers 16, 16a and guidestrip 12<c>, and is severed by a knife 13. The severed strip is forwarded by a blade 14 carried by an arm 14a actuated through a linkage from the cam 15b. The leading edge of the blade is slotted to intermesh accurately with the strip-feeding rollers 2, 3, and rises clear of the strip on the return movement. The chambers 4, 4<a> are similarly slotted to accommodate the rollers 2, 3. The filling may be ejected by a plunger 6 and subdivided during or after ejection into single or double length tips as described in Specification 413,655. Preferably, a paper tube 17 is severed by a cutter and engaged by one of a series of spoons projecting from a disc 18 intermittently rotated by a toothed segment 19<a>. A friction roller carries the tube on to the spoon and against the disc 18. As the tubes come into alignment with the plunger 6 a gripper 23 holds it during ejection of the filling from the chamber 4, the rear end of the filling being allowed to project slightly from the tube. Exact registration is effected by a plunger 24 with the assistance of a gripper 25. The complete filling and tube are discharged by a plunger. In a modification the chamber 4 is elongated, and the loosely folded strip ejected laterally into an extension of the chamber 4 wherein it is pressed to circularcross-section by a plunger. The wrapped sticks may be reduced to an exact multiple of the length of filter-tip by passage between grinding members, the lengths being carried in channels in a rotating drum.
