Title: Guiding a draw cable during cable-pulling operations
IPC: H02G1/06
Filed: 1980-05-01
Abstract: A method of drawing a supply cable through a duct by means of a draw cable and a winch, includes the use of a flexible incompressible sheath 1 through which the draw cable is passed, and which is attached at one end to a prop located along the draw cable and at the other end to the winch frame. As the draw cable is tensioned by the winch, the pull on the winch frame is balanced by the compressive force developed in the sheath since it is trapped between the winch frame and the prop. The preferred form of the flexible incompressible sheath consists of a plurality of vertebra-like metal bobbins 2 with complementary hemispherical end faces and each having an axial channel 6 the bobbins being enclosed in a flexible hose 3 having end fittings 4, 5 suitable for plugging the sheath into a socket. The flexibility of the sheath permits the operation of the draw cable with a curved lie, and the sheath will transmit a compressive force without distortion since it is not compressible. <IMAGE>

Filed: 1980-06-04
Abstract: A fluid temperature indicator comprises a temperature sensor 92 located in the outlet of a fluid mixing valve (not shown) receiving at its inputs hot and cold fluids via respective manually operable control valves. The sensed temperature is compared at 96, 98, 112 with a predetermined temperature range and indicator lights 100, 102 are illuminated as appropriate. Light 100 or 102 is illuminated when the sensed temperature is respectively above or below the predetermined range, both lights 100, 102 being illuminated when the sensed temperature lies within the predetermined range. The lights 100, 102 are associated with or incorporated into the control handles of the manually operable control valves. The lights 100, 102 may have different colours; alternatively, audible warning devices or tactile display devices may be used. If the sensed temperature deviates too far from the predetermined range, additional control valves are automatically actuated. To conserve battery power, a flow sensor 114 is employed so that the indicator circuitry is energised only when fluid is present in the outlet of the fluid mixing valve. <IMAGE>

Title: Cathodes for electrolytic furnaces
IPC: C25C7/02
Filed: 1980-12-04
Abstract: The invention relates to cathodes of electrolytic furnaces, for use in the production of metals, in particular aluminium, where the cathode is formed by a liquid metal (14). The liquid metal (14) contains, apart from an uppermost freely movable layer ("a") of at least 2 mm, a bed (16) of particulate material, which rests on a floor (10) of the furnace and is inert and solid at operating temperatures of the furnace. As a result, the movement of the liquid metal (14) is suppressed or retarded, and the interpolar distance ("d") to the anode (22) can be lowered to 10 to 25mm. The bed in the liquid metal can be subdivided into smaller regions by dividing walls (20), and formed of TiB2, TiC, TiN, ZrB2, ZrC and/or ZrN, or SiN bonded SiC or SiON. <IMAGE>
Patent GB-2067250-A (GB)
Title: Change speed gear
IPC: F16H61/70
Filed: 1981-01-09
Abstract: An input shaft 19, 21 carries high speed range and low speed range input gears 27 and 25 and a reverse gear 43. A forward synchronized clutch 29 can selectively couple either of the gears 25 and 27 to the input shaft. A non-synchronized reverse clutch 45 can couple the reverse gear 43 to the input shaft. The gears on the input shaft are in constant mesh with gears on a counter-shaft 55, via gears on a reverse counter-shaft in the case of the reverse gear 43. Gears on the counter-shaft are also in constant mesh with gears on a gear shaft 65 provided with clutches 85 and 87 for selecting three speeds in either speed range. A gear 73 fixed on the gear shaft 65 is in constant mesh through a gear 75 with a gear 81 fixed on the output shaft 83. When the vehicle is stopped and reverse is to be engaged the reverse gear 43 is stopped because one of the clutches 85 and 87 will already be engaged while the input shaft still rotates because of drag through the main clutch. Gear clashing is nevertheless avoided because the selector mechanism for the clutches 29 and 45 is arranged, in going from neutral to reverse, momentarily to engage the clutch 29 with the gear 27 (which is also stopped) before engaging the clutch 45, whereby the input shaft is stopped before the reverse clutch is engaged. <IMAGE>

Patent GB-2079463-A (GB)
Title: NMR imaging method
IPC: G01R33/561
Filed: 1981-03-13
Abstract: To produce image information from an object it is subjected to a continuous static magnetic field along a Z axis and to sets of sequences of magnetic field gradients Gx, Gy and Gz. Spins in a selected plane X-Z are excited by rf pulses and an associated Gy gradient. The selected spins are subjected to a reversed Gy gradient together with a Gx gradient. The Gy gradient is then switched off and the direction of the Gx gradient is then repeatedly reversed. During the action of each subsequent reversal of the Gx gradient, a small Gz gradient is provided. Each reversed Gx gradient is held constant for a sufficient time for a free induction decay signal to be generated, providing a multiple echo of the spins in the selected plane. Alternate signals are time-reversed, then both the time- reversed and non time-reversed signals are subject to Fourier transformation. <IMAGE>
