Title: Soil cultivating implements
Inventor: VAN DER LELY CORNELIS
IPC: A01B33/10
Filed: 1983-10-11
Abstract: In a soil cultivating implement, such as a rotary harrow, which comprises a plurality of soil working members 3 rotatably carried in a row by a hollow frame portion 1 that extends substantially horizontally perpendicular to the intended direction of operative travel of the implement, each soil working member 3 comprises a tine carrier 4 whose opposite ends are provided with tine holders 5 in which two tines 7 are arranged. Each tine 7 is of substantially circular cross-section and is provided at the front and rear, with respect to the intended direction of operative rotation of the soil working member 3 concerned, with projecting ribs 9. A resilient retaining pin 10 entered in a bore will co-operate with any chosen one of a plurality of notches or recesses 11 in each tine to allow the tines 7 to be downwardly spaced in the holders 5 to compensate for wear. The lower ends of the tines 7 are steeply bevelled and each holder 5 comprises a forwardly and outwardly bulging rib 12 that will assist in working the soil when the implement is adjusted for deep penetration of the soil working members 3 into the ground. <IMAGE>

Title: A drive unit for motor vehicles with a hydrodynamic torque converter
Inventor: FORSTER HANS-JOACHIM
IPC: F16H47/08
Filed: 1983-10-27
Abstract: A drive unit comprises an hydrodynamic torque converter 12, 13, 41 and an epicyclic overdrive gear unit 17 which may be interposed into the drive line between the input shaft 14 and impeller rotor 12 by means of a gear-shift element 15. To enable the torque converter to participate independently of the overdrive gear unit 17, the input shaft may additionally be brought into a driving connection with the impeller rotor 12 by means of a freewheel clutch device 19 for the traction or drive operations which blocks lagging of the impeller rotor in the rotational drive direction and does permit overtaking (over- running). The gear shift element 15 is operatively disposed between the overdrive gear unit 17 and the impeller 12, or a non-rotary housing component 20. <IMAGE>

Title: Casting chain
Inventor: SALMONS JOHN ARTHUR
IPC: B22C9/30
Filed: 1984-03-01
Abstract: Chain is cast in a mould comprising identical upper and lower halves each including a sequence of cavities (30, 31) fitted with identical core-pieces (C1, C2) which abut when the two parts of the mould are assembled. Each cavity is formed with a space (V1) co-operating with a corresponding space (V2) in the respective core-piece to define half of a vertical link, of which the other half is defined by corresponding spaces in the other half of the mould. The abutting faces of corresponding core pieces (C1, C2) are formed with spaces (H1, H3) defining the end portions of adjacent horizontal links, of which the central portions are defined by pairs of spaces (H2) in mating surfaces of the two parts of the mould and the opposite end portions are defined by similar spaces in the next adjacent pair of core pieces. A runner (20) extends along the junction of the two parts of the mould and communicates with the lower part of each space and a riser (24) communicates with the upper part of each space. <IMAGE>
Patent GB-2142423-A (GB)
Title: Production of liquid hydrogen
Inventor: MURRAY SMITH DR ERIC
IPC: F25J1/02
Filed: 1984-03-06
Abstract: A method and apparatus for producing liquid hydrogen in which water is electrolysed under pressure to generate separate streams of oxygen and hydrogen. A buffer cooling circuit is provided between two streams in order that heat can be removed safely from the hydrogen product stream by direct or indirect heat exchange with an inert medium flowing in the cooling circuit. At least some of cooling and/or work required in the cooling circuit is provided by expanding the oxygen stream. Preferably, heat is exchanged between at least some of the inert medium and the low pressure oxygen stream. The invention requires only compression of the feed water so avoiding the work necessary in prior art processes to comprise feed hydrogen gas. Also, use of the high pressure oxygen to provide work and/or cooling required elsewhere in the plant. As compared with conventional liquefaction processes, the economies are sufficient to enable the production, on a commercial scale, of liquid hydrogen for use as aircraft fuel to replace the usual fossil based fuels.

Title: Boat with improved hull
Inventor: WAWRZYNEK JOSEPH
IPC: B63B1/04
Filed: 1984-05-17
Abstract: A boat having a hull which has straight lines (25) in the hull plane normal to the central axis of the keel (22), the straight lines all making the same acute angles with the keel center line (20). Preferably the straight lines (25) extend beyond the water line to the chine (24). The freeboard portion (lines 27) above the chine (24) is inclined inwardly from the chine towards the keel center line (20). The boat remains substantially level as it increases speed under engine, or wind, thrust. An inward slant of the above water freeboard portion tends to deflect wind without undue sidewise tilt of the hull. <IMAGE>

Title: Fuse for an alternating current power circuit
Inventor: OAKES MARTIN CHRISTOPHER
IPC: H01H37/76
Filed: 1986-07-14
Abstract: A fuse for an alternating current power circuit in the medium voltage (3.3 kV to 38 kV) range. The fuse comprises a sealed chamber and a first electrode (41) is mounted within the chamber, the first electrode having a substantially circular periphery (42) and being electrically connected to a first terminal (3) to which a first conductor may be connected. A second electrode (35) is arranged with a conductive surface internally of the chamber, the conductive surface being spaced from the first electrode. A coil (10) is connected in an electrical path between the second electrode (35) and a second terminal (18) to which a second conductor may be connected. An additional electrical contact (44) is mounted within the chamber and in direct electrical connection with the second terminal, and a fusible element (43) directly electrically connects the first electrode (41) and the additional electrical contact (44). An electronegative halogenated medium fills free space within the chamber. The normal current path between the first and second terminals and through the fuse is by way of the first electrode (41), the fusible element (43) and the additional electrical contact (44). The arrangement is such that when the fusible element (43) breaks, the resulting fault current forms an arc between the first electrode (41) and the additional contact (44), one root of the arc subsequently commutates from the additional contact (44) to the second electrode (35), the fault current flows through the coil (10) and induces a magnetic field, the magnetic field causes the arc to rotate around the first electrode in the electronegative medium, and the arc is thereby extinguished, so interrupting the fault current.
