Filed: 1969-07-30
Abstract: 1280236 Endless conveyers SANDCO Ltd 30 July 1969 [1 Aug 1968 13 May 1968] 38314/69 Heading B8A [Also in Division F2] A seal for sealing a gap provided for the flow of a fluid medium between a fixed part and a movable part such as for sealing the gaps 21 through which a conveyer belt 3 may pass into and out of a pressure chamber 2 comprises a seal element 19 which is movably-mounted on the fixed part and yieldably-urged towards the other by pressure means having a resultant which is directly opposed to the resultant of forces exerted on the seal element by fluid flowing under pressure through the gap. As shown, the conveyer belt 3 passes through a pressure chamber 2 supplied with gas from a source 18, the gas pressure tending to lift the seal element 19 being opposed by springs 16 which are off-set so as to balance the forces and maintain the seal element parallel to the belt. In a second embodiment, Figs. 3 and 4 (not shown), sealing elements (26) are provided one on each side of the belt (22) which in this case consists of two separate belts with the material to be treated between them. The sealing elements are mounted on plungers (27) which are urged towards the belt by the gas pressure until the pressure in the sealing gaps are balanced by the plunger pressures; alternatively the plungers may be operated by a pressure source which is independent of the pressure chamber. In Figs. 5 and 6 (not shown), the sealing elements are resiliently-mounted and urged towards the belt by the gas pressure, the elements being extended axially on the side remote from the pressure chamber so that the forces on each side of the elements balance and maintain the elements parallel to the belt. In Fig. 7, the sealing elements 50 are each mounted by a pair of flexible tubes filled with a pressure medium which exert a force F R . The opposing forces F P  produced in the sealing gaps 55 set up torques M and the elements are maintained parallel by means of lever arms 60 supported at their free ends by pneumatic cushion devices; alternatively, each sealing element may be mounted by a pair of flexible tubes one being filled at a pressure higher than the other so as to maintain the element parallel.

Title: Internal shuttering for the cells of caissons and other hollow bodies of concrete
IPC: B28B7/30
Filed: 1928-12-28
Abstract: 303,174. Hollandsche Maatschappij tot het Maken van Werken in Gewapend Beton. Dec. 30, 1927, [Convention date]. Caissons.-The internal shuttering for use in moulding in concrete the cells of caissons forming the foundations of waterside embankments, quays, &c., consists of a flexible wall supported by an internal framework which, when lifted, withdraws the wall from the concrete and enables the shuttering to be raised and reset. Fig. 2 shows in plan a flexible sheet-metal wall 1 attached to vertical beams 2 supported, in groups of four, by top and bottom T-irons 4. On these irons rest the supporting-frame, consisting of two pairs of crossed beams 7, 8 combined into a rigid whole by vertical angle-irons 9-12 and by bars 14 connecting the beams 7, 8 to the inner ends of the T-irons 4. The outer ends of the irons are connected by pivots 15. Spring bolts 19 are connected by cables 20 to a central vertical bar 21. At the upper ends of the vertical beams 2 are fitted horizontal beams supporting boards forming the working-floor or upper surface of the device. To remove the shuttering, the pivots 15 are first with-drawn, and the whole frame 4-12 is raised. The wall 1 at first remains stationary, but presently draws away from the concrete, until the frame 4-12 touches the horizontal beams at the tops of the vertical beams 2. The bolts 19 are drawn in, and the whole shuttering is raised for a distance about equal to its depth. It is then reset in place, and a further section of the concrete structure is cast round it. In a modification, the beams 7, 8 are replaced by four beams forming a quadruple cross, the ends of the beams abutting centrally on the T-irons 4. In a similar modification, inclined bars connect the beams of the quadruple cross to the middle beams 2, and to secure the walls 1 in their outer position loose horizontal beams are forced against the beams 2 by wedges driven between them and the beams of the quadruple cross. The spring bolts 19 are replaced by rigid rods.

Title: Improvements in or relating to fluid flow regulators
Inventor: ALLEN GEOFFREY REX
IPC: G05D16/06
Filed: 1957-12-11
Abstract: 908,891. Fluid-actuated valves. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 10, 1959 [Dec. 11, 1957], No. 38493/57. Class 135. A fluid flow regulator comprises a diaphragmactuated valve member 13 loaded by a spring 15 and which responds to demand pressure at a remote point in a delivery line 18 and in accordance with the velocity of flow through a Venturi 19 adjacent the regulator in the delivery line 18. A duct 18a connects the throat of the Venturi to a chamber 17 beneath the diaphragm so that on inspiration by the user of, e.g., breathing-equipment, pressure beneath the diaphragm is lowered to permit the valve to open. Once open the pressure in the chamber 17 will be related to Venturi throat velocity and on a high flow rate being demanded the pressure of the fluid at the expansion end 19a of the Venturi will be maintained at a correspondingly high level. In a modification the Venturi 19 is replaced by a converging injector nozzle in the line 18 with the nozzle outlet shown adjacent the opening of the duct 18a. It is not necessary for the duct 18a to be precisely opposite the throat of the Venturi or the nozzle outlet, it may be at any point in a low-pressure region affected by the high velocity of fluid flow.
