Abstract: Process and apparatus for regulating the interpolar distance to compensate for anode consumption in electrolysis cells. 
<??>As a result of the large differences in the position of the anode beam in the upper and lower position, the current path and the power loss become too large during lowering or raising and substantial variations in the magnetic field arise. The lowering of the anode necessary to remove the anode effect results in a rise in the bath level which may bring about flooding of the carbon anodes and leakage of the melt. 
<??>To avoid these disadvantages, at least one further anode beam (2) is movably arranged parallel to, and at a variable distance from, the first anode beam (1), the anode rods (3) being attached either to the first or the second anode beam and the anode beams (1, 2) each being connected to a drive running in the opposite direction. This makes it possible to adjust the individual anodes precisely to the to anode consumption at a particular time. 
<??>Regulation of the interpolar distance in electrolysis cells, in particular those used for aluminium melt electrolysis.

Abstract: PCT No. PCT/SE90/00823 Sec. 371 Date Jun. 15, 1992 Sec. 102(e) Date Jun. 15, 1992 PCT Filed Dec. 12, 1990 PCT Pub. No. WO91/08946 PCT Pub. Date Jun. 27, 1991.A method and a device for power transmission from a motor having a supercharging assembly, particularly a supercharged diesel-engine (7), to a gear (3) with a surface water driving propeller mechanism (4) mounted in a boat of the planing variety and preferably with a large propeller with a large pitch. A turbine coupling (10), which can be filled to a variable extent, is mounted between the supercharged motor (7) and the gear (3). The motor is designed to drive the pump portion (15) of the turbine coupling (10), and the turbine portion (17) of the turbine coupling (10) is connected to the input shaft (6) of the gear (3). The turbine coupling (10), when the boat is started, is emptied completely or partially, in such a way that it is at least partially disconnected from the gear. The motor is then accelerated to such a speed that the supercharging assembly of the motor (7) is connected. The turbine coupling is subsequently quickly filled with hydraulic medium, so that the propeller mechanism (4) is influenced by the substantially maximum output of the motor, caused by the supercharging assembly. When the boat has reached its planing speed, the motor speed in the desired way is reduced and/or the extent of filling of the turbine coupling is reduced, but no to a lower speed than that the boat will be propelled with a speed which is somewhat larger than the planing limiting speed. The invention also relates to the use of a turbine coupling in planing boats having gears of the above-described variety.

Title: Magneto-optical recording medium
Inventor: OHTA KENJI
IPC: G11B11/10
Filed: 1991-02-12
Granted: 1995-11-14
Abstract: A magneto-optical disk having a magnetic layer and a conductive layer laminated on a transparent substrate, and having a lubricant layer provided on the conductive layer.          Recording and reproduction on and from the magneto-optical disk are performed by means of a flying head.  The flying head glides above and lands on the lubricant layer.  The magneto-optical disk can therefore be removed from the device easily since a magnetic head does not adhere to a recording medium.  Further, a depressing force exerted on the flying head is controlled so as to maintain a constant floating gap between the flying head and the recording medium.    The   depressing   force   is   controlled   by electrostatic capacity between an electrode, provided on a bottom face of the flying head, and the conductive layer.          Consequently, highly reliable recordings can be made since a magnetic field intensity applied to the magnetic layer becomes constant.   It is  desirable that  the  lubricant layer be composed of an organic binder containing a powder belonging to the ethylene tetrafluoride resin family.

Title: Method for radiotelephone autonomous registration
Inventor: MULLINS JEFFERY L
IPC: H04W88/02
Filed: 1990-08-22
Granted: 1993-11-16
Abstract: A cellular radiotelephone autonomous registration method. The radiotelephone attempts registration when a clock count transmitted by the system equals or exceeds the radiotelephone's threshold count. The radiotelephone then scans available channels for proper signal strength and attempts to seize that channel. If the channel seizure fails, the threshold count is updated with the clock count plus a random integer and the next channel seizure attempt is made when the next master clock value equals or exceeds this value. This method increases the length of time between failed channel seizure attempts, thereby decreasing the load on the radiotelephone's power source.
