Title: Selective sepn. of gaseous component by pressure swing adsorption - using radial gas flow to optimise utilisation of adsorbent bed in cylindrical vessel
IPC: B01D53/047
Filed: 1978-04-28
Abstract: A gas component is adsorbed in a pressure swing adsorption process in which the gas mixt. is passed through a bed of adsorbent material and an adsorbent zone is created in the bed and gradually displaced through the bed. Just as the adsorbent zone reaches the farthest limit of the bed in the direction of flow of the gases, the pressure in the adsorbent vessel is lowered by initially continuing to remove gas from the discharge end and then removing gas from the feed end and finally purging the vessel with low pressure gas, pref. the same gas as that obtd. from the initial pressure redn., until the adsorbed component is entirely removed from the bed. The vessel is then brought up to pressure again and the process is restarted. In order to obtain optimum utilisation of the adsorbent bed with the minimum possible length of adsorbent zone and correct exit velocities, the flow is arranged radially through the bed which is contained in a cylindrical vessel. The radial flow enables optimum utilisation of the bed to be achieved without increasing the dia. of the cylindrical vessel.

Title: Seal for large pipe socket and spigot joint - has inwards and outwards projecting lips with stiffening sleeve
IPC: F16L17/035
Filed: 1979-05-02
Abstract: Cylindrical elastomeric seal is enclosed over at least part of its length by a flanged cylindrical sleeve of more rigid material, e.g. polypropylene. Outer dia. of the sleeve is smaller than the internal dia. of the socket of the pipes between which a sealed socket and spigot joint is to be made. In addn. to its inwards projecting lip, seal also has an outwards projecting lip which extends along the end edge of the sleeve into a plane outside the outer diam. of the sleeve. Seal has a collar projecting outwards between which, and the outwards projecting lip, the sleeve is clipped. Sleeve has a widened counterbore to receive the collar, with a flange which rests on the end face of the socket. Seal compensates for discrepancies in dia. and rotundity in the 300-500 mm pipes to be joined without additional operations being necessary. It can be stored separately and fitted using very little effect.

Title: Method and apparatus for inductively measuring the conductivity of a fluid
IPC: G01R27/22
Filed: 1993-06-23
Abstract: Method and apparatus for inductively measuring the electric conductivity of a fluid, employing an insulated combination, to be placed in the fluid, of a driver transformer and a measuring transformer which are spaced apart, each have an annular (toroidal) core and are electromagnetically coupled by a fluid loop passing through the annular cores, and an electronic driver/measuring circuit. A reference voltage is fed to the driver transformer, and a measuring voltage induced by the current passing through the fluid is taken off the measuring transformer, thus cancelling the effect of the inductance associated with the current passing through the fluid loop. The partial current caused by the said magnetic flux is measured in the measuring circuit, and this is cancelled by an inverse compensation current of equal amplitude being fed back to the measuring transformer. The partial current proportional to the conductivity of the fluid is measured in the measuring circuit by said partial current being readjusted to zero in the measuring transformer by an inverse current of equal amplitude being fed back to the measuring transformer.

Title: Radial mining method
Inventor: ROYE H
IPC: E21C35/00
Filed: 1978-02-04
Abstract: The process is for mining a subterranean mineral seam, for complete removal of the mineral over a selected circular area, and for minimum distance of transport of supplies and product. A large dia. central vertical or slope shaft is drilled at a selected point on the surface of the earth, down to the selected seam of the mineral. The shaft is enlarged at its base in the seam to a selected radius to form a workroom. A small dia. central shaft is drilled parallel to the first shaft adjacent the workroom. A radial shaft is drilled in the seam from the workroom, to a selected radius by any conventional method. A second radial shaft is drilled by using a continuous mining method directed radially at a selected angle to the axis of the first radial shaft.

Title: Improvements in or relating to control valves
IPC: F16K31/44
Filed: 1978-07-11
Abstract: An installation control valve, for example for use in a fire fighting sprinkler installation, comprises a pivotal butterfly valve disc co-operable with a movable stop, which in one position abuts the valve disc to retain the valve closed against pressure forces acting thereon. A retaining mechanism is releasably held to resist stop movement and so prevent valve disc opening but is operable under a predetermined condition to permit stop movement from said one position to a second position. When the stop is in the second position, unequal pressure forces on either side of the valve disc cause same to move thereby opening the valve.

Title: Fluid planet turbine, engine propeller, vane
Inventor: PLESIVCNIK ANDREJ
IPC: F03B17/06
Filed: 1996-03-12
Abstract: The Fluid planetary turbine, engine, propeller or windmill has its planetary wings (1, 2, 3, 4, 5, 6) entirely submersed into the fluid. They travel around of central regulation cogwheel, and during one revolution - circle 360 DEG , rotate themselves each around its axis for 180 DEG . Therewith is factually improved the unwanted effect of cavitation corrosion. This rotation of planetary wings (1, 2, 3, 4, 5, 6) is provided by the planetary cogwheels (8, 9, 10, 11, 12, 13), which are driven by means of idle gears (14, 15, 16) and they rotate around the still standing central regulation cogwheel (17). In the case that the planetary wings are driven, we speak about the turbine, engine and windmill; in the case when we drive these planetary wings, we speak about the propeller, or the pump.

Title: Electric device switch
Inventor: SEMROV ANTON
IPC: H01H9/10
Filed: 1997-10-02
Abstract: The electric device switch, which can be made using a fuse operating with a fuse-link or without fuse, basically consists of a chassis (1), which includes two equal mirror-type halves (2), where both chassis differ only by the fact that the chassis featuring the fuse is extended for the length of the seat (3) for the fuse-link. The chassis (1) halves (2) feature beds (6, 7, 8) in the form of ribs for permanent contacts (9, 10) and contact (11) of the fuse-link (4). The moving contact (12) is guided by the rib-like guides (13), supported by a spring (14) and directly controlled by a shaft (15). On its opposite side the shaft (15) is gripping at the switching handle (17) by which the switch is manually activated. The handle (17) is mounted to the axis (18), which lies in both chassis (1) halves (2). The shaft (15) is apart from the handle (15) guided in each chassis (1) half (2) by an arched rib (21), having its center in the center of the axis (18). Inside both chassis (1) halves (2) there are two arched wings (26) located next to the axis (18), having its center concentrically to the axis (18) or rib (21) and which are made by a recess (27) as a shaft (15) bed when the terminals are open. The arc (19) is eccentrically positioned compared to the axis (18) or the wings (26), so that in the position of the handle (17) when terminals are open, the end of the arc (19) is in the rest position (20) between the concavity (27) and the axis (18) while the other end of the arc (19) is in the rest position (20') on the virtual extension of the wings (26) across the concavity (27). This ensures the fitting of the shaft (15) inside the concavity (27) in the most open position of the handle (17) and the release of pressure on the handle (17) by the spring (14) via the shaft (15).
