Abstract: A high power high voltage transmission system consists of three highvoltage cables which are suspended from a transmission tower in insulated relationship with one another and with respect to the ground. Each of the cables is shown as a gas-insulated cable having a central high voltage conductor and an outer conductive housing which is insulated from the central conductor. The line-to-line voltage of the central conductors of each of the high voltage cables is 765 kV, while the potential between the outer conductive housings of each of the cables is 345 kV. The total right of way and height of the support tower is that needed for a conventional 345 kV transmission system even though the system is used to transmit 765 kV line-to-line voltage.

Abstract: Apparatus for automatically feeding bushings into a press for moulding covers for storage batteries. It includes a pipe (1) for conveying the bushings (6), said pipe being divided into branches (8, 9, 10, 11) each of which communicates with a bore (28, 28') provided in a first moving part of the press (2), push rods being linked to the stationary part of the press (2), which push rods can each be inserted in one of said bores (28, 28') during the translation movement of said moving part, studs being provided on a second moving part of the press (2) and each being disposed adjacent to one of said bores so that firstly, before moulding when the press is closed by the translation movement of the two moving parts such that they abut against the stationary part of the press (2), the push rods push a bushing (6) into each bore (28, 28') until the bushing mates with the stud and secondly, after moulding when the press (2) is opened, another bushing ( 6) drops by gravity into the bore at the end of said push rod.

Abstract: In a loading vehicle comprising a pick-up drum (21) with resilient fingers (23) for picking up straw or other crop material from the ground and a conveyor drum (26) with conveyors (27), fitted in rows, for carrying the material picked up into the vehicle, the pick-up drum and the conveyor drum are disposed with respect to each other so that the conveying direction of the material is abruptly changed when the material is introduced into the path of motion of the conveyors. This produces a damming-up effect causing the material to be distributed over the entire conveyor front, which minimizes the tendency of squeezing between conveyors and the housing wall defining the conveyor duct (34) at one side. The change in conveying direction also causes a certain compaction of the material, resulting in a better utilization of the available volume. The structure allows short spacing between the conveyors (27) and thus closely spaced knives in the conveyor duct so that the material e.g. blades of grass can be cut in small pieces which are suitable for ensilage.

Filed: 1986-05-07
Abstract: The present invention discloses a new method for obtaining a crystallized phosphoric acid of relatively high purity starting with conventional phosphoric acid. The new method is based on crystallization of orthophosphoric acid hemihydrate from the phosphoric acid. Massive nucleation which would lead to the formation of unprocessable masses is avoided in the new method by providing unusually large amounts of fine relatively pure seed crystals of orthophosphoric acid hemihydrate and operating the crystallization process under conditions which favor crystal growth on the seed crystals and disfavor the occurrence of secondary nucleation. To prevent the crystallizing magma from reaching a viscosity which would render further processing difficult the present invention provides for recycling raffinate in an amount suf­ficient to maintain the solids content of the crystallizing magma below about 40%.

Abstract: A fire isolation device having a valve designed to close after a given temperature has been reached by a fusible nose member in the form of a sleeve of fusible material. The device has a passageway therethrough and a self-closing valve member having a poppet and a seat disposed in the passageway with the poppet being biased toward the seat to a valve closed position. At least one aperture through the nose member provides for continuous fluid flow through the device around the poppet and the seat. The nose member is positioned to hold the valve in an open position against the bias on the poppet. The seat has a flow path on its outer end dimensioned to fit the nose member and a flow path towards its inner end larger in diameter than the nose member in an area occupied by the aperture to permit flow therethrough when the nose member holds the valve in an open position. The nose member is made of a material designed to melt in the neighborhood of 700 DEG  F. when the fire isolation device is exposed to 2000 DEG  F. for 15 minutes, for example, after which it will collapse into the larger diameter permitting the bias to close the valve. The nosse member is designed to melt prior to an attached component in order to prevent fluid leakage at the component. The remainder of the parts of the device are made of a higher temperature resistant material. In a second embodiment a bi-directional device is provided in which valve and nose members are positioned in both ends thereof.
