A hydrostatic extrusion apparatus comprises a cylinder 3 defining an extrusion chamber 8, an end cap 5 with a through opening 16, means 6 for securing the cap to the extrusion end of the cylinder, and a combined billet guide and die holder 1 axially slidable and pivotable in the cap so as to be movable, with the cap secured, from an axially aligned billet loading and die-locating position to an angularly displaced position wherein the die holder is accessible for die handling purposes. Cap 5 is secured to the cylinder by a split locking ring 6 having at its end 11 segmental cam surfaces which co-operate with complementary surfaces 14 on the cap to press the latter axially whilst it is rotated. The cap opening 16 is of elliptical shape, Fig. 4 (not shown), on the minor axis X-X of which is pivotally mounted by means of trunnions 17, a bearing block 4. The die holder 1 slides in this block and carries the die 7 which is pressed and sealed in the extrusion chamber by a ring of wedges 26 operated by hydraulic rams. After hydrostatic extrusion of a billet from chamber 8 through die 7, the wedges 26 are withdrawn, die holder 1 is retracted axially and is then rotated through 180 degrees about axis X-X. Die 7 is then removed, the die holder is returned into its operative position and a fresh billet is fed through bore 21 into the extrusion chamber. Die holder 1 is again rotated for replacement of the die, the wedges 26 are inserted and the fresh billet is extruded. Instead of moving the die holder through 180 degrees, a die handling device may operate through spaces between flanges 11, 13 to remove the die after pivoting the die holder through 90 degrees. The locking ring 6 may be used to secure a back pressure container on to the cylinder 3.

Title: Improvements in and relating to hydraulic pistons
Inventor: DICKINSON RONALD SYDNEY
IPC: F16K47/10
Filed: 1967-10-05
Abstract: 1,245,406. Hydraulic piston. ARMSTRONG PATENTS CO. Ltd. 3 Oct., 1968 [5 Oct., 1967], No. 45425/67. Heading F2S. A cylindrical hydraulic piston 10, Fig. 1, has an axial bore 12 which is threaded at 14 to receive a piston-rod 16 therein and which combines with a number of blind branches 18 to define one recess. At least one of the branches 18 is connected by an arcuate passage 20 to an annular groove 22 formed in the rear face of the piston. A disc valve closure member 24 overlies the groove 22 and is spaced from said rear face by a washer 26 having radial peripheral notches 28. The member 24 is urged towards said rear face by a cup spring 30, the latter being retained by a washer 32 and by a circlip 34 which is received in a groove 36 of the piston-rod 16. The latter is provided with a radial bore 40 and an axial bore 42 which facilitate the passage of fluid flow from the rear to the front face of the piston. An end 44 of the piston-rod 16 forms a valve seat for a closure member 46 which is urged by a spring 48 housed in a cap screw 50, the latter being received in the bore 12 of the piston. In use when the piston moves to the right, hydraulic fluid is forced through the passage 20 thus causing the member 24 to lift against the force of the spring 30. Movement of the piston to the left forces hydraulic fluid through the bores 40 and 42 in the piston-rod 16, lifting the valve member 46 from its seat 44 against the force of the spring 48. The notches 28 in the washer serve to allow fluid to pass through the piston in either direction when the force is too small to lift the members 24 or 26. In a modification the closure member 46 is carried on a member 54, Fig. 3 (not shown) which is slidable in an aperture formed in the cap screw 50.

In the arrangement described, an excessive temperature rise sheath 17, which is of copper, expands more than rod 12 which is of nickel-steel and draws the rod 12 inwardly through bushing 37 so that contact unit 15 is opened through lever system 38 and plunger 39. The unit 15 may be automatically reset when the temperature falls. In an alternative construction the terminal connectors of the heating resistance 10 extend from opposite ends of the sheath and one of them is secured in the end 17 of the sheath by means of insulation to act as the rod 12 of the rod and tube thermal actuator. The metal mounting flange 14 to which the ends 16, 17 of the heating element are staked may be formed from a bar which in cross-section has a thicker central portion to which the ends of the element are secured and thinner flexible side flanges provided with mounting holes. This construction enables the thicker central portion to remain unstressed when the thinner flanges are secured to a curved vessel. The side flanges may be extended longitudinally to press a conventional thermostat against the outer surface of the vessel wall.

Abstract: 1,243,824. Knitting. G. BILLI & C. S.p.A. 8 Oct., 1968 [9 Oct., 1967; 6 Dec., 1967], No. 47547/68. Headings D1C and D1K. The toe of a stocking is formed of at least two layers by turning the end of the fabric tube with the aid of welt instruments in a welt dial in the same manner as a turned welt is usually formed. Prior to retransference of the loops from the welt hooks back to the needles a yarn or yarns is or are wound spirally about the fabric portion extending between the needles and welt hooks and pulled sufficiently tightly to constrict the fabric and in effect close the tube. The ends of the spirally wound yarn or yarns is or are secured in the fabric and on completion of the turns the welt hooks transfer their loops to the needles. This construction provides an effective closure of the toe. The turned portions forming the toe may have a stitch variation compared with the fabric body and the central portion intermediate the two layers and about which the yam or yarns is or are wound may be knitted of a finer or elastic yarn. The wound turns may also be elastic yarns. A double turned portion for the toe having in effect four layers may be knitted by first knitting one portion of fabric extending between the needles and welt instruments followed by a second portion of fabric which extends between the welt instruments and needles so as to provide two layers whereafter the yarn turns are wound around both layers and the two layers subsequently doubled on themselves to close the toe.

In an illuminated display means in which a projector 1, Fig. 1, projects light through a film on to a panel 2 of light-sensitive devices each of which is connected through circuitry 3 to an electric light bulb mounted in a corresponding position on a display board 4, each bulb is illuminated to an intensity determined by the intensity of the light projected on to the corresponding light sensitive device. In the circuitry, Fig. 2, a single phase A.C. 50 c/s. supply is passed via rectifiers 9 and 10, which produce output signals comprising a series of uni-directional pulses having a frequency of 100 c/s., Fig. 3 (not shown), to a silicon controlled rectifier 11, an R.C. circuit 12; 13 and a trigger circuit 14. Resistor 12 comprises one of the light sensitive devices and is such that its resistance varies when the intensity of the light falling upon it varies, thus varying the charging time of capacitor 13. The R.C. circuit is connected to the trigger device 14 which is itself triggered by the output from rectifier 10 to produce pulses, Fig. 4, not shown, which are applied to the controlled rectifier 11 to render it conductive, the delay in the pulses being dependent upon the value of the resistance 12. The silicon controlled rectifier may thus be made conductive at any time between the start and finish of each of the uni-directional pulses applied by rectifier 9, varying the voltage waveform across terminals A and B, Fig. 5 (not shown), and thus varying the illumination of bulb 15. The bulb can thus be controlled to be at any intensity from full on to full off.
