Title: Diaphragm equalising means and valve assemblies for fluid pressure totalisers
IPC: F15C4/00
Filed: 1960-03-01
Abstract: 940,240. Fluid-pressure servomotor control systems. HAGAN CONTROLS Ltd. March 1,1960 [March 2,1959 ], No. 7161/60. Heading G3P. Also in Division F2] A valve member 64 operable to set up an output pressure in a chamber situated below a diaphragm 59 in response to the resultant of pressures acting on diaphragms 36, 36<SP>1</SP>, 43 consists of parts controlling an inlet 66 to the chamber and an outlet 631 from the chamber and is actuated by a beam 12 movable about a fulcrum constituted by a leaf spring 31 which is adjustable to alter the effective lever arms of the beam. The diaphragms 36, 43 are rigidly connected to each other by an element 45 and the diaphragms 36<SP>1</SP>, 59 are similarly connected together by an element 60, and extensions 48, 48<SP>1</SP> and 51 of diaphragm clamping screws locate the elements 45, 60 laterally on the beam. Adjustable stops 100, 101 coact with the beam which may be stabilized by a device 102. Each diaphragm has an annular corrugation so that its effective area can be varied by altering the position of its central portion relative to its peripheral portion and such alteration is carried out simultaneously and in opposite senses on each pair of diaphragms 36, 43 and 36<SP>1</SP>, 59 by adjustment of screw-pressed wedges 90, 91 by which the beam 12 is clamped to the elements 45, 60. By this means the effective area of the diaphragms of each pair can be equalized. The diaphragm 59 can be biased upwardly or downwardly by a spring 77 having a connection with a screw 80 coacting with a rotatable element 81.

Title: Textured yarn and process for making same
IPC: D02G1/20
Filed: 1973-02-14
Abstract: 1424472 Textured, interlaced yarns BURLINGTON INDUSTRIES INC 14 Feb 1973 7255/73 Headings D1F and D1W A method of producing textured air jet interlaced yarn comprises feeding at least one yarn through false-twist texturing means including heat setting means, and passing the so-textured yarn through an air jet 22 where air is passed concurrently with the yarn through the jet to interlace the yarn. In a preferred embodiment two multifilament yarns 2, 4 are fed over a heater 12 to two false twist spindles 14, 16 and then fed together through the air jet 22 and taken up on package 20. The air jet preferably comprises a stepped tubular yarn passage 26, the air inlet pasage 30 making an angle of 45-75 with the yarn passage 30. The yarn is overfed to the jet and the air pressure is in the range 15-30 psig. The yarn produced by the above method has repeating sections of #-1 inch in length, each section comprising an open portion of bulked multifilaments and a shorter node portion in which the filaments are interlaced. When two false-twisted yarns are used they are preferably false-twisted in opposite directions. The two yarns are also preferably differently coloured or differently dyeable; they may also be of different material e.g. nylon, polyester or acetate.

Title: Improvements to parachutes
Inventor: GREGORY JAMES
IPC: B64D17/00
Filed: 1960-03-02
Abstract: 899,455. Parachutes. GREGORY, J., and G. Q. PARACHUTE CO. Ltd. March 1, 1961 [March 2, 1960], No. 7365/60. Class 4. A parachute comprises rigging lines 2, each of which consists of a first portion 10 extending over at least a part of the canopy 1 and a second portion 11 extending beyond the periphery of the canopy, the first portions being less elastic than the second portions. In this way, the shock on opening is reduced by the portions 11, while the less elastic portions 10 do not reduce the effective diameter of the canopy during stable descent. The canopy material preferably stretches to the same degree as the portions 10, and the canopy gores 5 may be square rather than bias cut. Each rigging line may be of nylon or silk so woven or braided that the two portions have different elasticity, or may be in two portions joined by engaging loops at the canopy periphery. In the latter case, the loop in each portion 10 is formed so that the canopy edge is sandwiched between two parts of the loop. In the Figure, the canopy is composed of four panels having adjacent sides 14, 14a laced together as in Specification 742,417. An annular gap 16 is formed between the panels and a crown piece 15 having a vent 8 in which is a rigid floating ring 13. Each shroud line portion 10 extends along a gore seam from the canopy periphery to the ring 13, and is in two parts joined together in gap 16, as at 17, so that any panel can readily be removed from the canopy. In alternative canopies, each shroud line portion 10 extends from the canopy periphery to the hem of a crown vent, or crosses the vent and extends to the diametrically opposite point on the canopy periphery. An anchorage ring such as 13 may be located in the crown vent of a conventional gored canopy. Each shroud line may be attached to its corresponding gore seam at discrete points, or may form a core within the seam and be continuously stitched therein. Specification 722,442 also is referred to.

Filed: 1940-04-26
Abstract: 540,747. Tubular films. HEAVEN, H. S. April 26, 1940, No. 7569. [Class 2 (ii)] Tubular films, e.g. sausage casings are formed by extruding a cellulosic solution such as viscose from an annular die into contact with a setting liquid, passing the film in a partly set condition over a mandrel adjustable in respect of shape and of position in the apparatus and thereafter subjecting it, while still in the partly set condition, to regulated inflation by the controlled admission or removal of fluid to or from the interior thereof ; the fluid may be admitted and removed. The inflation may be maintained until the tubular film has been set substantially completely, the setting liquid, which for viscose solution may be an aqueous solution of ammonium sulphate, may be supplied to the interior of the tubular film between the die and the mandrel, the mandrel may be expansible and adjustable to regulate the diameter of the tubular film, and the diameter of the mandrel is preferably somewhat greater than the diameter of the die orifice. As shown the cellulosic solution is supplied through a pipe 15 to the annular orifice 14 of the die 13 disposed in the setting solution 12 and the tubular core 20 of the mandrel is slidably and adjustably mounted in the inner tube 18 of the die and carries the expansible member 21 formed of inflatable rubber or other flexible material bound to the core by clips 22, 23. Water is supplied from a pipe 24 to the inside of the member 21 to expand it, setting solution is supplied to the space between the inner lip of the orifice 14 and the member 21 through a pipe 25 and conduits 26, 27 and a pipe 28 passing through the core 20 and terminating above the level of the setting liquid is connected through a two-way cock 29 with an air pressure pipe 30 and an exhaust or vacuum pipe 31. The setting liquid supplied through the pipe 25 is maintained under a pressure slightly greater than that of the surrounding bath so that the extruded tube 32 is stretched while it is being set and guided on to the member 21 the inflation of which is adjusted to stretch the tube the desired extent; the end of the tube as it leaves the Member 21 is sealed and the tube is inflated by air supplied through the pipe 30 until the gases evolved-in the tube during the process attain sufficient pressure, when the cock is turned to bring the pipe 28 into communication with the pipe 31. The tube 32 passes from the member 21 in a slightly inclined upward direction, through the regenerating and washing apparatus, to a pair of nip rollers which draw the tube through the apparatus. The core may be made of glass or stainless steel. Specification 408,774 is referred to.
