Granted: 1991-07-09
Abstract: ABSTRACT OF THE DISCLOSURE         In a process for edging metal strips, especially nonferrous metal strips, by means of an edging machine wherein the longitudinally driven metal strip is guided between an upper and a lower linear guide and cutting tools are disposed successively along the line of movement of the strip, on either side of the linear guides.  It is proposed according to the invention that a liquid or gaseous fluid be forced out of the central part of the linear guides at individual points along the line of the movement, into the clearance between the metal strip and the linear guides.  In a linear guide for carrying out this process, provision is made according to the invention such that, in each linear guide face confronting the metal strip, there are a series of grooves running longitudinally along the center of the guide, the grooves being separate from one another and connected to inlets for the fluid.  These measures assure, by means of the pressure cushion that forms in operation, that the friction and hence the driving force become extremely low, that the chips produced from the material are reliably kept out of the area between the linear guide tracks and the metal strip, and that the surfaces of the metal strip are protected against damage.

Abstract: Disclosed is herein a disc drive system comprising: a magnetic disc, spindle motor means for rotating the magnetic disc, transducer means for transducing information from and onto the magnetic disc and biasing means for biasing the transducer means against the magnetic disc with different biasing pressure according to the rotation speed of the magnetic disc.          When the rotational speed of the disc is increased, the pressure due to the air flow generated by the rotation of the disc is raised.  A spacing distance of the magnetic heads from the disc tends to increase.          However, according to the preferred embodiment, since the pressure of the leaf spring, that is, a contact pressure between the magnetic heads and the disc is increased, the spacing distance of the magnetic heads from the disc may be maintained substantially constant.      Therefore, although the rotational speed of the disc is increased, a spacing loss, for example, is not increased, thereby enabling good reproduction.

Granted: 1992-07-28
Abstract: ABSTRACT Figure 1) The invention relates to charge balancing of cells (3,4) of rechargeable batteries (1,2), such as that based on the electrochemical reaction between a negative electrode of a lithium-aluminium alloy and a positive electrode of iron sulphide. The battery (1,2) has means to balance the charge in the cells of the battery comprising connection means (8) to enable distribution of hydrogen between all of the cells (3,4) and means (9,10) to remove the hydrogen from the cells (3,4).  As the battery (1/2) is started up and hydrogen is formed from the reaction of water with the lithium, each cell (3,4) will discharge to zero charge and thus they will all recharge from a common base point. The battery (1,2) may further include means for maintaining the cells (3,4) within the battery (112) at a uniform state of charge by monitoring the charge on each cell (3,4) to detect if the charge on a cell (3,4) becomes out ofbalance with the other cells (3,4) and adding hydrogen to the cells (3,4) when the charges are detected to be out of balance to ensure that all the cells (3,4) self-discharge.
