Title: Improvements in or relating to arrangements for adjusting the flow of liquids
IPC: E02B7/18
Filed: 1953-02-13
Abstract: 724,416. Injectors. PONSAR, Y. M., and HYDRAULIQUE & URBANISME. Feb. 13, 1953. [Feb. 20, 1952; April 7, 1952] No. 4163/53. Class 71. [Also in Group XXIX] In means for regulating the flow of liquid from an upstream section to a downstream section by means of a siphon containing gas in its upper part and with the flow of gas into the siphon being controlled by a valve, the latter is governed by a member sensitive to the level of liquid in the siphon arm pertaining to the upstream section. In an embodiment, the downstream arm 72 of the siphon is enclosed by the upstream arm 71, and the valve 78 controlling the flow of air into the upper part 83 of the siphon is actuated by a hollow float 80. As the liquid flows into the upper end of tube 72, it entrains air from chamber 83 through a tube 82 depending from the float, and this entrained air is collected and led away through a conduit 89 as compressed air. The depression produced by air sucked past valve 78 can also be applied for use through a conduit 76.

Abstract: 252,068. London Electric Railway Co., and Baker, W. S. Graff-. Feb. 14, 1925. Operating doors pneumatically and by crank and lever mechanism.-A door which is movable bodily on supporting rollers travelling in guide tracks intersecting one another at rightangles is operated by arms which are each hinged at one end to a stationary support to swing about an axis intersecting and perpendicular to the centre lines of the guide tracks, the arms having each a pivotal connection at the other end with the door, the axes of pivoting at the two ends of each arm being parallel to and so disposed that a plane containing them approximately bisects a line joining the centres of the rollers or other guide elements. The door 10 is mounted on a pair of operating-arms 17 pivoted to door brackets 15 and to a hinge red 18 mounted in bearings on the door post. Rollers 21, 22 on the lower edge of the door engage guide tracks 23, 24 which are formed in the floor and intersect one another in the axis of the rod 18. The axis of the pivotal connection between the rods 17 and the door is disposed midway between the rollers 21, 22 so as to bisect a straight line joining the centres thereof when the door is in a displaced position. A hinged strip 25 with a rubber edging 26 is fitted to the free edge of the door. The door is opened and closed by a compressed air motor 29 with link and lever connection with the rod 18. As shown, the crank 30 is connected by a rod 33 to one of the arms 17 so that the major length of the rod may remain hidden behind the wall 27. The members 33, 30 are connected through a sliding block 34 held between a fixed collar 35 and a spring 36.

Abstract: 837,581. Drawing tubes; cupping. ACCLES & POLLOCK Ltd. Oct. 28, 1958 [Feb. 10, 1958], No. 4221/58. Class 83 (4). In apparatus for (hawing metal tubes a reciprocatory head consists of two parts interconnected by a pair of cam controlled spring- loaded toggle links one part of the head being adapted to carry a mandrel extending through the other part, which is provided with a thrust collar for a tube carried on the mandrel. In operation a tube is loaded on a mandrel f ; the head a, b is moved forward by a ram e, thrust collars h feed the tube into the dies g and the forward end of the mandrel, which is shaped as shown to correspond to the internal diameter and length of the butt to be formed on the tube, then feeds, the tubes through dies g. The head initially travels between the parallel edges k of the cams i and the die contracts the forward end of the tube on to the mandrel. Continued movement of the head causes rollers m on the links to roll on to inclined edges n of the cams thereby retracting the collar h on the forward part b of the head relatively to the part a at a rate which accommodates the lengthening of the tube under the action of the die. After passing through the dies the tubes are stripped off the mandrels by a stripping collar q on the return movement of the head a. More than two tubes may be treated concurrently.

Abstract: 1,220,355. Laminates for thermal insulation. FEDERAL-MOGUL CORP. 29 Jan., 1968 [13 April, 1967], No. 4463/68. Heading B5N. [Also in Division F2] A laminate for thermal insulation of hightemperature ducts, especially in aircraft, comprises a metal foil which has been pressed into intimate association with a thermosetting-resinimpregnated fabric while the resin was cured, and is formed over its area, and throughout its thickness, with a stiffening pattern, e.g. of diamond-shaped depressions. Preferably, the foil is of soft aluminium, polished on one side to be reflective, and the fabric is of glass-fibre impregnated with a phenolic resin containing a dull black pigment. An insulator may be formed on a mandrel 22 bearing a diamond-mesh pattern by pressing a sheet of foil 17 into close contact with the mandrel and then wrapping an impregnated sheet of fabric 18 about it and pressing down. Alternatively, the foil and fabric may be pre-laminated. A plastic separator 27 is inserted where the ends of the sheets overlap one another. An over-lapping strip of impregnated fabric 26 is then applied. The laminate is then cured at high temperature in a vacuum bag, or under pressure derived from a heatshrinkable tape, removed from the mandrel, and applied as a shell 11 to a duct 10, spacing- member 14, which may be secured to the shell 11 or to the duct, producing an air gap 13. One edge of the laminate is then sealed, by adhesive over the other edge and beneath the joint strip 26. Expansion joints, Fig. 4, may be sealed by rings 32 of silicone rubber bonded to the adjacent shells by adhesive, and some of the spacing- members may take the form of metal rings 16 by which the insulators may be supported. Insulators for bends and junctions may be formed as half-shells 12, to be subsequently jointed together about the ducting.

Title: Improvements in or relating to Projectiles.
Inventor: SMITH JOHN GEORGE
IPC: F42B10/46
Filed: 1916-03-27
Abstract: 124,781. Smith, J. G. March 27, 1916. Projectiles.-Relates to devices arranged at the nose of a projectile to prevent deflexion when entering water at a low angle, and consists mainly in mounting co-axially on the nose of the projectile a device provided with ribs of relatively large cross-section having substantial water-engaging surfaces, and which allows the projectile to rotate relatively thereto when the device is engaged by the water. In the form shown in Fig. 3, a cap having outer ribs a and inner grooves b is secured to the nose of the projectile by setscrews c. The ribs a may be straight or curved, and the grooves b may be filled with lubricant or opened to the water. The screws c are intended to shear when the projectile strikes water, and may be replaced by any other yielding attachment such as : (1) cement or a low melting-point metal or alloy in the grooves b and in corresponding recesses in the nose of the projectile; (2) spring catches; or (3) magnetic attraction. In an other form, Fig. 11, plates e are hinged at f to the ribs a and swing out under the action of centrifugal force and a spring g when lugs' o on the plates are released during flight by the unscrewing of a winged nut m. A spring n helps to drive the nut forwards. A bearing j is interposed be tween the projectile and the cap. The ring j is made in three pieces with interlocking V-shaped ends to permit its insertion within the cap, and is then secured to the nose of the projectile by set-screws k ; or the ring is made in one piece of Babbitt-metal cast in the cap separately and then secured to the projectile by set-screws k, or cast between the cap and the projectile so as to run into the holes for the set-screws, which are then not required. Instead of releasing, the plates e by a winged nut during flight, they may be released on leaving the ,gun by a spring plunger which is pushed back by air pressure, or they may be released on striking water by the shearing of pins which normally lock them in the folded position. The cap may be made of the same material as armour-piercing caps so as to serve that purpose also.
