Patent GB-2196171-A (GB)
Title: Double-cell battery
Inventor: JOHNSON PHILIP JAMES
IPC: H01M6/42
Filed: 1987-09-23
Abstract: The invention provides a double- cell battery (10) which comprises a pair of electrochemical cells connected in series. The battery has a casing (12) divided by a fluid-tight partition (14) into two chambers (16, 18). Each chamber is divided into two compartments by a ceramic tube solid electrolyte separator (20, 22). One of the cells has active anode and cathode materials (36, 32) which are contained respectively in one of the tubes (20) and outside the tube (20) in the associated chamber (16); and the other cell has active anode and cathode materials (38, 34) which are contained respectively outside the other tube (22) in the other chamber (18) and inside said other tube (22). The cell chambers (16, 18) are electronically connected to each other. An advantage of the invention is that it provides a battery 10 comprising two cells arranged in series and requires only two purpose-built current collectors. The batteries 10 may be assembled into larger batteries or modules 40 (Fig.2). <IMAGE>

Title: Hot-rolling seamless pipes in a plug mill
Inventor: HAUSLER KARL HEINZ
IPC: B21B17/12
Filed: 1990-10-25
Abstract: In a process for hot-rolling seamless pipes in a plug mill, a pusher guides the hollow block into the roller nip of the plug stand, the working rolls of which roll out said block, drawing it over the plug of a stopper rod in a reduction pass to reduce the wall thickness, and form a pipe. After the reduction pass the pipe is conveyed back to the entry side of the plug stand in a return pass with the working rolls open by means of return rollers arranged in a stand on the exit side in order to perform at least a second reduction pass. The pipe is smoothed between the return rollers without or with only a slight reduction in the return pass.

Title: Rotary drum shear
Inventor: SATO HISASHI
IPC: B23D25/02
Filed: 1991-09-03
Abstract: A shear for cutting a strip of metal moving along a pathway includes two opposed parallel horizontal drums (2, 6) extending transversely at the pathway and situated on opposite sides of it. Each drum has a shaft (3a, 3b; 7a, 7b) at each end and carries a cutting blade (45, 46) extending transversely of the pathway. The shafts of each drum are supported by respective checks (5a, 5b; 9a, 9b), the chocks of at least one of the drums being movable towards the other drum. Hydraulic cylinder means (11a, 11b; 13a, 13b) are connected to each movable chock and arranged to move the associated drum between a first position in which the two drums are relatively remote and a second position in which they are relatively close. Gears (14a, 14b; 15a, 15b) mesh with one another when the two drums are in the second position. Drive means (30) synchronise the two drums. A speed sensor (33) produces an output signal when the said speed reaches a predetermined value and causes the drums to move into the second position. <IMAGE>

Patent GB-2252282-A (GB)
Title: Steering apparatus with variable steering angle ratio
Inventor: SHIMIZU YASU
IPC: B62D5/22
Filed: 1992-01-24
Abstract: The steering input shaft 12 is externally threaded at 12a to form part of a ball screw mechanism 20, the ball nut 15 of which is accommodated in a conversion nut 17 which thus moves linearly along the axis L1 when the steering wheel is turned, and has a neutral position. A lever member 26 is operatively coupled to the steerable road wheels, and is angularly moved about an axis C that extends perpendicularly to but is offset from the axis L1 when the steerable road wheels are steered, the lever member 26 having a neutral position. The conversion nut 17 is angularly moved by a motor 40 via worm gearing 25, 39 in response to sensed road speed and steering angle ratio. An arm 23, which is part of the conversion nut 17, is positionally variably held in engagement with the lever member 26. The position in which the arm 23 engages the lever member 26 is located within a plane P (see FIG. 2) containing the axis C, and is movable on a path (i.e., the bearing 32) equidistantly spaced from the axis L1. This arrangement prevents the neutral position of the steering wheel and the neutral position of the steerable road wheels from being affected by a change in the steering angle ratio. The motor 40 operates only when the ratio is to be varied, so consumes less energy. <IMAGE>

However, the heat dissipation rate at the ends of the stack exceeds that at the center such that all of the discs cool to a predetermined temperature concurrently. <IMAGE>
