Title: Extrusion press with rotary die carrier
Inventor: ROSENTHAL SALLI ALFRED
IPC: B21C23/21
Filed: 1960-02-03
Abstract: 939,034. Extrusion presses. LOEWY ENGINEERING CO. Ltd. April 28, 1961 [Feb. 3, 1960], No. 3914/60. Class 83 (4).  A metal extrusion press having a carrier which is rotatable to bring dies successively into operation has means for displacing the die carrier longitudinally along the centre-line of the press relative to the platen and billet container and means for longitudinally displacing, relative to the carrier, that die which lies on the centreline of the press. The carrier 34 and die 26 are movable axially together or in opposite directions to uncover a short length of the extruded article without axial movement of the container 16 to enable the discard to be sheared either in front of the die, Fig. 2, or behind it, Fig. 3. The carrier 34 is rotatable on a shaft 38 by a motor 40 through reduction gearing 42, the gear on the shaft being splined to permit axial movement of the shaft and carrier by two hydraulic actuators 44 and a cross-head 48 on the shaft end, the shaft assembly being carried by the platen 24. The shaft 38 is rotated when a second die 35 is to become operative, each die assembly 23 comprising a pressure ring 30, die-holder 28 and a bolster 32. A split distance-piece 36 (not shown) is insertable between the die-assembly and platen; it is in place during extrusion but is removed thereafter to enable axial movement of the die assembly towards the platen to be effected by two hydraulic actuators 54 carried within the platen. The piston-rods 56 of these actuators have forked ends whereby the heads of rods 58 attached to the die-holder are engaged to effect withdrawal of the die assembly 23 from the face of the container 16, as shown in Fig. 2, so that a saw 64 mounted on the press may be swung into position to sever the discard in front of the die, the container being then rotated in its carrier 20 about an axis 22 to bring another billet into alignment with the press axis whilst a motor-driven brush 74 cleans a container from which a discard has been ejected. If severing of the discard is to be effected behind the die assembly 23 the actuators 54 are operated to move die-holder 28 back towards the container, against compression springs 60, Fig. 3. The container itself is axially movable by means disclosed in Specification 904,593.

Abstract: 371,083. Tensioning warps in looms. COTTON, R., 3, Lyndale Avenue, Hasling- den, Lancashire. Feb. 13, 1931, No. 4515. [Class 142 (ii).] To obtain cover, the warp threads are divided by a stationary rod or bar F and by a control rod or bar G carried by arms g on the back rest D, which is oscillated by lever mechanism K, k, h and a cam H<1> on the bottom shaft. At the beat-up with the crank B at front centre, alternate warp threads are tensioned by the oscillation of the arms g and consequent lowering of the bar G at one pick, Fig. 4, and raising at another pick, whilst when the crank is at back centre the bar G is in a central position. The shedding is so timed that the shed is closed at the beat up and fully open when the crank is at back centre as shown in Fig. 3, thus allowing a maximum time for picking. In a modification, two stationary bars F, Fl, Fig. 7, are employed. In another modification, the movable control bar is carried by arms on the front stationary bar, and in another modification two bars G, G<2>, Figs. 10 and 10b, are carried by the arms g<1>, whereby both sets of warp threads are tensioned at the beat up, but one set more than the other. The Specification refers to a known method wherein the shed is open at the beat up and the healds are operated to strain the bottom of the shed.

IPC: B60T8/18
Filed: 1960-02-09
Abstract: 946,921. Vehicle brakes. ROLLS-ROYCE Ltd. Jan. 3, 1961 [Feb. 9, 1960], No. 4551/60. Heading F2F. In a vehicle braking system, the braking torque on the front wheels is increased in relation to that on the rear wheels in proportion to the load transfer on deceleration. A brake pedal 1 is fulcrumed about a point 3 to raise a link 5 having a lost motion connection 5a with a link 6 pivoted at 7a to a beam 7 contacting rollers of two piston valves 16, 17. The end of the link 6 remote from the beam is connected to the pedal 1 through a link 8 and a " feel " spring 12. The valves 16, 17 control the pressure of brake fluid through the front, 22, and rear, 23, brakes respectively; a continuous flow being maintained from reservoirs 20, 21 by pumps 18, 19 through brake cylinders 22a, 23a, chambers 26, 27, passages 29, 30, chambers 31, 32 to the reservoirs 20, 21. Light actuation of the pedal 1 causes slight compression of the "feel" spring 12 and movement of the link 6 in the direction of the arrow to move the valves 16, 17 and cause their pistons 35, 36 to throttle the passages 29, 30 and produce a pressure rise in the system to apply the brakes. As the pedal movement is small, the lost motion slot 5a allows the link 5 to rise without changing the position of the beam 7. Heavier brake application requiring greater pedal movement causes the link 5 to raise the link 6 and beam 7 to increase the travel of the valve 16 in relation to the valve 17 to provide increased braking on the front wheels proportional to the load transfer produced by such braking. In a modification, the front brakes are actuated both by cylinders in the circuit of the valve 16 and extra cylinders in the circuit of the valve 17.
