Title: Improvements in prestressed concrete piles
Inventor: SYKES WALTER BURRANS
IPC: E02D5/58
Filed: 1952-09-25
Abstract: 712,674. Concrete piles. STENT PRECAST CONCRETE, Ltd. Sept. 24, 1953 [Sept. 25, 1952], No. 24041/52. Class 68(2) A pre-stressed one-piece concrete pile is formed by threading one end of a high tensile steel wire cable c through a thin-walled metal tube b and distending the other end to form a cage-like structure d round a metal loop e, concrete then being cast around the cage d, the tube b, and other reinforcements including four longitudinal steel bars k surrounded by mild steel links l, m, and steel rod mats n close to the end of the pile. A sleeve i is also placed around the lower end of the tube band the neck of the cage d, hooks j being bent round the tube b for carrying purposes. A pointed cast iron shoe may be fitted to the toe of the pile. After the concrete has set and the cage d is anchored in the toe of the pile, the cable c is tensioned, e.g. by a hydraulic jack, and is held in tension by a wedge, or clamp f, the ends of the cable c<SP>1</SP> being cut and spread within a recess at the head of the pile. Grouting is then injected into the tube b until it emerges from an outlet g in the toe of the pile. In an alternative arrangement a tubular passage is formed by casting concrete round a collapsible rubber hose which is withdrawn when the concrete has set, the cable being threaded through the tubular passage, and further concrete being cast round the cage d and on the main portion of the pile. Should the pile be driven short the projecting portion of the head can be broken away and the bars k can be bent at right angles to link with a pile of a superstructure cast thereon; alternatively, should the pile require to be driven further, the bars k can be exposed and more bars can be spliced thereto, the head of the pile being extended by casting more concrete. In a modification the links m are at wider intervals, the concrete being further reinforced by a helically bent mild steel rod surrounding the tube c.

Abstract: 1,131,559. Bottling. HOLSTEIN & KAPPERT MASCHINENFABRIK " PHOENIX " G.m.b.H. 24 May, 1967 [24 June, 1966], No. 24135/67. Addition to 1,078,708. Heading B8T. In a counterpressure filling machine, excess liquid which has entered the gas return pipe after the bottle &c. has been filled is discharged to waste after removal of the filled bottle &c. instead of being supplied to a succeeding bottle or a separate liquid reservoir. The filling head comprises a valve block 1 with a liquid valve 2, a shifting valve 3, a gas valve 29 and a return gas valve 4. A filling pipe 5 contains a return gas tube 6, which may be connected by the bore 7 and the valve 4 to a riser pipe 8 situated inside the container 9 which holds the gas and liquid, e.g. beer, with which a vessel 14 is to be filled. Initially, an empty vessel 14 is placed in position with the expansion valve 3 closed, and the gas valve 29 is opened to allow gas to flow into the vessel 14 under pressure. The valve 29 is then closed, and the liquid valve 2 opens to admit liquid into the filling pipe 5. At the same time, the return gas valve 4 is opened and retained by the pawl 27 allowing displaced gas to flow up the tube 6 and into the container 9. When the liquid in the vessel 14 covers the orifice 10, the level of the liquid rises up inside the gas return tube 6. The valves 2 and 4 are now closed, and the shifting valve 3 actuated so that the shaft 21 moves to a position wherein the top of the vessel 14 is connected via the ring passage 13 and the bore 12 to the exterior at the opening 15, hence allowing relief of the pressure in the vessel 14. As the shaft 21 moves further, it causes the valve shaft 22 to move also, connecting the upper end of the filling pipe 5 with the exterior, thus allowing the liquid in the pipe 5 to fall into the vessel 14 which is then removed. The liquid in the return gas pipe 6 is retained up to this point, but the valve 4 is now opened briefly so that the liquid is expelled by gas pressure prior to the arrival of another vessel for filling. Vessels are held in position by the member 16 which is suspended from the valve block 1 by a gripper 17.

IPC: G01N11/14
Filed: 1920-08-20
Abstract: 171,774. Frink, R. L. Aug. 20, 1920. Viscosimeters.-The apparatus is particularly intended for measuring the viscosity of highly viscous material such as molten glass, and comprises an angularly displaceable or rotatable member contacting with the material, and means for measuring the speed of rotation of this member produced by a constant torque, or the torque required to produce a constant angular velocity. The invention also includes means for measuring the angular velocity or displacement of a member which contacts .with the viscous material and is subjected to the torque produced by the rotation at a substantially constant speed of the receptacle containing the viscous material. In the form shown in Fig. 1, the member 1 of refractory material such as fire-proof clay contacts with the glass &c. 2a in a pot 2, and is carried by a watercooled shaft 4 passing through a water-cooled bearing 6 on the roof 7 of the pot. The shaft 4 is driven by a shaft 10, which is subjected to a constant torque as by a falling weight 11: The shaft 10 is geared to a shaft 16a carrying a centrifugal device 16, which actuates the pin of a recorder 17. In a modification, the shaft 10 is rotated at constant speed and the power absorbed is recorded. In the form shown in Fig. 5, the member 1 dips endways into the glass &c. 20<a> and the pot 20 is rotated at constant speed. The resultant rotation of the shaft 21 carrying the member 1 is communicated to the shaft 26 carrying the centrifugal device 25 for operating the recorder 24.

Abstract: 429,589. Light-current relays. BERNHEIM, G. W., 17, Rue Jean Leclaire, Paris. Sept. 1, 1933, No. 24267. Void [Abridged as open to inspection under Sect. 91 of the Acts, March 13, 1934]. [Class 38 (v)] A sensitive relay, more especially for use in conjunction with photoelectric cells, is provided with means for vibrating the whole of the relay or a part thereof in order to prevent sticking of the relay contacts. The sensitive relay effects control through a second relay which is shortcircuited by the sensitive relay contacts when in the unoperated position, but completes its own maintaining circuit after being operated by operation of the sensitive relay. As shown in the Figure, the sensitive moving coil relay A fed by currents from photo-electric cells is vibrated as a whole or in part by an electromagnet D fed by A.C. Alternatively, a selfinterrupting magnet fed from D.C. may be employed, the vibration produced preventing sticking between the movable contact arm and the relatively fixed contacts a<1>, a<2>. When the former of these is engaged the second relay B is short-circuited, but when the contact a<2> is engaged by sufficient energization of the moving-coil the relay B is energized, completing a maintaining circuit at contact b and a control circuit at contact b<2>. These contacts are opened when the sensitive relay contact again engages contact a<1> and short-circuits the operating coil B. The circuit of a controlled device J is completed at contact b<2> on operation of relay B.
