Abstract: 649,550. Load-handling trucks. BICKERSTAFF, L. N. July 2, 1948, No. 17894. Convention date, May 18. [Classes 78 (iii) and 78 (iv)] In a lift truck the load-handling attachment comprises a plurality of forwardly extending tines having gripping members secured thereto which, when said attachment is lifted, first engage the sides of the bottom bricks of a plurality of stacks of bricks and then lift said stacks. On either side of tines 18 and on the inside of tines 16, 17 are shafts 32 carrying, at spaced intervals, rubber gripping blocks (not shown) which engage the sides of bricks 71 when shafts 32 are rotated by cranks 39 and pull rods 59, 61. Relative movement between the tine frame 19 and a lift frame 41, operatively secured to the lifting chains 13 of the truck, is effected when the gripping blocks lightly engage the sides of bricks 71 and the lift frame 41 is raised, said movement, and the friction between the gripping blocks and bricks, causing springs 57, 58 to extend, springs 62, 63 to compress and rods 59, 61 to rotate shafts 32 so that the bricks are firmly but resiliently held by the gripping blocks. Continued lifting of frame 41 then serves to lift bricks 71 together with the stack thereabove. On lowering the frame 41 collars 67 on rods 59, 61 abut against a channel member 53, secured to said frame 41, so positively disengaging the grippers from the bricks 71. A bolt 68 forms an adjustable stop member to limit relative movement between the frames.

Title: Improvements in or relating to processes and apparatus for sprinkling granular or pulverulent substances on to band-like webs or foils, more particularly roofing felts and the like
IPC: D06N5/00
Filed: 1957-06-05
Abstract: 845,667. Sprinkling granular substances on to webs. DOTT, C. June 5, 1957 [June 22, 1956], No. 17902/67. Class 140. A process for sprinkling a granular or pulverulent substance on to an adhesive-coated web comprises carrying the substance by conveying means from a container to the adhesive-coated uppermost surface of said web, the web being then displaced so that said upper surface becomes the lower surface, any granular substance not adhering to said web being returned to said conveying means other than via said container and any of said substance falling to either side of said web of material also being returned to the conveying means, the returned substance being subsequently re-sprinkled on to the web. As shown (Fig. 1) a web 2 travels round cylinders 3 and 4 so disposed in a frame that the direction of travel of the web is changed. A stripper 13 engages the surface of cylinder 3 in order to remove from it any sprinkled substance carried by it. The sprinkling apparatus consists of a container 6 and a conveyer 7, the latter travelling round rollers 8 and 9. The sprinkled material falls from container 6 on to conveyer 7 and thence on to the web 2. Any material falling to either side of the web falls on to guide-plates 18 (Fig. 2) and thence into the annular trough 15 formed in the periphery of wheel-like conveying devices 14 disposed on each side of the frame. The trough is sub-divided by blades 16 into compartments 17. Guide-plates 19 direct the material which falls out of the troughs as the wheels turn back into the container 6 and thence to the conveyer 7. The web 2, coated with adhesive, passes below the conveyer 7 and is covered with sprinkling substance. As it passes round roller 3 the upper surface becomes the lower and loose substance falls off on to roller 3 and is conveyed back to the conveyer 7 by the stripper 13.

Abstract: 923,116. Valves. CARL ZEISS JENA VEB. May 23, 1960, No. 18179/60. Class 135. A needle valve, particularly for high-vacuum apparatus, comprises a needle 5 finely adjustable by means of a rotatable knob 9 adjustably secured to a differentially threaded spindle 4 and rigidly secured to a threaded bush 6, the threaded bush being limited in its rotation by a pair of stops 1, 7 co-operating with each other at a point in the rotation of the knob which is determined by the setting of the spindle relative to the knob, the ratio of needle length and needle thickness being such as to allow elastic deformation of the needle after it has fully closed the valve seat and shortly before the engagement of the stops thereby preventing overstressing of the needle. The bush 6 is clamped to the spindle by means of screws 8 which, to set the stops 1, 7, are loosened and the needle screwed down until a vacuum-tight fit in its seat is obtained. The bush is then rotated on the spindle 4 until a very small gap is produced between the two stops; the screws are then tightened to lock the bush in this position. In operation, when the stops are abutted, the small gap is taken up by the flexure of the needle as indicated at 5.

Abstract: 841,071. Hydraulic brakes. CITROEN S.A., A. June 14,1957 [July 19,1956], No. 18910/57. Class 103 (1). [Also in Group XXIX] In an automatic clearance adjustment device for an hydraulic control system, e.g. an hydraulic braking system, a hollow body 1 having a chamber 2 filled with hydraulic fluid is connected with the movable member to be controlled and a differential piston 8 is adapted to move to a predetermined limited extent within this chamber, the rear face of the piston being subjected to the pressure of the fluid fed through pipe line 10 from a source of fluid under pressure; the pipe line 10 also being connected with a chamber 2 through a non- return valve 11 permitting the ingress of hydraulic fluid into the chamber after the clearance has been taken up. The brake arrangement illustrated indicates a disc brake having an hydraulic cylinder 4 in which piston 5 is operatively connected to axially slidable brake lining pressure plate 5 against the force of return springs 13. When fluid from a pressure source is fed into pipe line 10, differential piston is displaced downwardly until it reaches its abutment such that a volume of liquid V has been displaced from chamber 2 into the cylinder 4 and other cylinders (if any) through pipe line 3<SP>1</SP> to take up the clearance of the brake. Further pressurization of the fluid in line 10 lifts spring-loaded valve 11 off its seat and allows fluid to pass into chamber 2.
