Abstract: 1,118,001. Cooling unspecified articles. CROMPTON PARKINSON Ltd. 14 March, 1966 [22 March, 1965], No. 12050/65. Heading F4U. [Also in Division B3] A chamber 5 contains a nozzle 8 which directs a jet of coolant against a relatively thin, heat conducting wall 6 of the chamber, the chamber also having an outlet or drainage tube 12 but being otherwise air-tight. In use, the wall 6 is placed in contact with a metal surface 1 to be cooled. This may for example be the wall of an aluminium or stainless steel pan to one side of which a stud 2 is to be welded or brazed, the cooling chamber 5 being placed at the other side of the wall to remove heat arising from the welding or brazing operation. The coolant may as shown be a liquid (e.g. water) or it may be a gas such as air. Where a liquid is used, the air space above the liquid level in the chamber prevents this level from rising above the jet outlet. The heat conducting wall 6 may be made of a flexible material so that the wall adapts itself to the contour of the surface 1 when pressed thereinto by spring pressure. The vessel 5 may be formed as a metal bellows (Fig. 2) which itself constitutes the loading spring, or separate springs (not shown) may be used.

Title: Yarn with snarling twist
IPC: D02G3/26
Filed: 1973-03-14
Abstract: 1453058 Snarl twist yarns COURTAULDS Ltd 13 March 1974 [14 March 1973] 12207/73 Heading D1F Yarn with snarling twist is produced by heating a heat-settable yarn having a non- circular e.g. trilobal or rectangular, cross-section to a temperature sufficient to set twist therein, forwarding the yarn in twisted condition to an edge and guiding it thereover and over a surface adjacent thereto under conditions which prevent some twist in the yarn moving past the edge. The yarn may be a single, doubles or multi-filament (in which latter case the individual filaments may be of circular cross-section) of synthetic e.g. polyamide (nylon 6) material. Initial twist may be imported by unwinding untwisted yarn overend from a package. The edge may be formed by the base of a notch in a plate which also provides the adjacent surface and around which the yarn may effect two passes on the first only of which the yarn may be drawn, the twist set therein and it may be at a lower temperature than on the second pass. As shown, yarn 5 from a cheese (not shown) passes through nip rollers 4, over and in contact (for about 90‹) with a hot pin 6, through a notch 12 in a steel plate 9, over the surface 14, through another notch 15, thence one and a half turns around a driven godet 17 and separator roll 18. Yarn is returned to pin 6 on which it moves in an arc in excess of 180‹ before returning to plate 9 and having at this stage been drawn (about three times) between rollers 4 and the godet. In a second pass, yarn 5 is guided through notch 22, over surface 14, through notch 23, thence to godet 17 and separator 18, effecting several turns therearound, and wind-up. The conditions (tension, speed, and the value of the angle at which yarn approaches the edge and forms with the adjacent plate surface) should be such that twist is held in the length of yarn between roller 4 and plate 9.

Title: Process and apparatus for timing the ignition of electric projectile fuses
IPC: F42C11/04
Filed: 1928-04-26
Abstract: 289,473. Rheinische Metallwaarenund Maschinenfabrik. April 28, 1927, [Convention date]. Addition to 273,338. Projectile fuzes.-Relates to time fuzes in which the energy of discharge of electric condensers is employed for igniting the primer. According to the invention, the time of ignition. is determined by varying the charging voltage of the condenser or condensers, instead of charging a condenser always to the same voltage, and varying the time of discharge oy means of an adjustable resistance, as in the invention described in the parent Specification. The Figures show fuzes in each of which the charging current is obtained from a source external to the projectile, contacts a<3>, a<4>, preferably formed as rings, being provided on the fuze body, and being adapted to engage with contacts arranged, for example, in the gun barrel or breech. In the fuze shown in Fig. 1, a single condenser a is provided, connected to the contacts a<3>, a<4>, amd to a hot-wire igniter c in series with a high resistance b. The time taken for the wire c to be heated by the discharging current sufficiently to ignite the primer depends on the voltage applied to the condenser through the contacts a<3>, a<1>. Another contact device, normally open, but adapted to be closed by inertia when the projectile is fired from a gun, may be inserted in the discharge-circuit of the condenser. The modification shown in Fig. 2 comprises two condensers e, f, adapted to be charged to the same voltage, upon the value of which depends the time required for ignition. The electrodes e<1>, f<1> are connected together over a spark gap g (or a high resistance) and an ignition device h consisting of a spark gap or a wire. A high resistance i causes the gradual discharge of the condenser e when the fuze is in action, so that a current, sufficient to cause ignition, eventually flows through the device h. 'The resistance i may be made adjustable, preferably by arranging it in a rotatable ring, and by this means an additional or alternative means of varying the timing of the fuze is providted. The means for charging the condenser or condensers may be provided within the projectile. For example, a permanent magnet, displaceable in a coil, may be used, and the voltage thus generated may be determined either by controlling the speed of the magnet by means of a brake, or by altering the number of turns in the coil. Specification 283,585 is referred to.

Abstract: 645,258. Gas turbines. BUCHI, A. May 9, 1947, No. 12597. Convention date, May 10, 1946. [Class 110(iii)] A gas turbine rotor 14, Fig. 1, is followed by a diffuser 15 the walls of which are surfaces of rotation generated by diverging lines 16, 17. The down-stream parts of these lines are straight and one of these parts may be radial. The gases are expanded in the turbine to below atmospheric pressure and are brought up to that pressure in the diffuser. In the construction shown in Fig. 1, the gases enter through passages 4, 5 separated by diametral walls and the separation may be continued through the diffuser. The flow through the turbine blading has both radial and axial components. The diffuser delivers radially into a chamber 20 of constant outer diameter but with an axial dimension which increases on both sides of the diameter from the lowest point to the exhaust opening 13 at the top. The casing comprises three portions 8, 11, 10 and the portion 11 may be divided axially. Cooling fluid is supplied to cavities 9 and 12. Cooling air is drawn from the delivery scroll 10 of the compressor 2 through passages 21, an annular space 22 and a packing 24 to the turbine delivery. The flow through the turbine may be axial and the diffuser may deliver axially into a volute chamber with a constant radial dimension and an increasing axial dimension. The volute chamber may be followed by a diffuser with a straight axis. The diffuser 15 may be preceded by a convergent portion produced by a hump 29, Fig. 9, or, by a parallel portion 34, Fig. 10, connected to the diffuser 15 by a constricted portion 35.

Abstract: 969,231. Dashpots. LANSING BAGNALL Ltd. April 5, 1962 [April 7, 1961], No. 12647/61. Heading F2S. In a dashpot arrangement for controlling the rate of rotation of a shaft 20 journalled in a bore in a boss 19 on the base 11 of a dashpot chamber having a peripheral wall 12 and a cover 14 an elongated flexible and sealed tube 21, made e.g. of polythene, nylon, or rubber and filled with hydraulic medium, e.g. silicone fluid, is arranged in the chamber against one half of the wall 12 concentric with the shaft 20 and a head 24 of the shaft 20, located in the chamber, carries a radially-extending arm 25 to the outer end of which the two plates 26, 27 of a roller carriage are pivoted at 29. Two rollers 31, 32 are mounted one at each end of the carriage, the roller 31 bearing against the tube 21 and the roller 32 being urged firmly against the wall 12 by a wire spring 33 acting between the shaft head 24 and a plate 28 which is connected between the plates 26, 27. The ends of the tube 21 protrude through corresponding diametrically-opposite slots 16 in the wall 12 and are clamped against the adjacent flattened outer surfaces of the wall 12 by fish plates 17 bolted at 18 to the wall 12. The pivot 29 is displaced a short distance from the line joining the centres of the rollers 31, 32 in a direction away from the head 24. The permissible swing of the roller carriage against the action of the spring 33 when the roller 31 is caused to bear upon the tube 21 is limited by an adjustable screw stop 35 which is threaded through a lug 36 in the shaft head 24 and is engageable by the web 28. In operation when the shaft 20 is initially turned in the direction of the arrow, Fig. 1, the roller 31 is pressed into the surface of the tube 21 so that the cage turns about the pivot 29 and the roller 32 moves away from the wall 12 the stop 35 limiting the distance the roller 31 penetrates into the tube 31. Continued rotation of the shaft causes the roller 31 to roll round the tube 21 fluid, transferred from one side of the nip between the roller 31 and the wall 12 to the other, offering resistance to the progress of the roller 31. When the shaft is rotated in the opposite direction the roller 31 lightly engages the tube 21 and the roller 32 rolls round the wall 12, a return spring from the shaft being provided if desired. The tube 21, which could be provided with a rubbing strip for the roller 31 to engage, may be formed in the arc-shape of the wall 12. The rollers 31, 32 may be interchangeable in the roller carriage so that the controlled direction of rotation of the shaft can be changed by interchanging the rollers and laying the tube 21 along the appropriate side of the wall 12. The invention is stated to be applicable also to a straight line tube 21 and a roller mounted for linear movement along the tube.
