Patent number: 4565334Abstract: An electrohydraulic drive for process line equipment, especially a spooler that winds and pays out an indefinite length of metallic strand, varies the output torque of a hydraulic motor by controlling its displacement and the pressure differential between its inlet and outlet. A valve controlled by a proportional actuator reduces the supply pressure of the hydraulic fluid in a feed line for the motor. A sequence valve located in a return line from the motor maintains the pressure at the motor outlet at a preselected and adjustable value. During braking, fluid from the return line is directed to a regeneration circuit that includes a flow divider returning one portion of the flow to the feed line and another portion to a supply reservoir. A servo-amplifier circuit includes an integrating amplifier that compares the actual rotation speed of the motor to a speed command signal. An analog multiplier produces a control signal for the proportional actuator.Type: GrantFiled: November 13, 1984Date of Patent: January 21, 1986Assignee: Kennecott CorporationInventor: Robert C. Ruhl

Patent number: 4564190Abstract: In appliances for practicing aquatic sports with water flowing upwardly over a sloping bottom surface a premature breakdown of the flow caused by the accumulation of portions of water slowed down by friction at the boundary faces is prevented by at least partially removing said portions of slowed down water. This can be done by sucking off at least the increasingly portions of slowed down water which are preferably refed to a return pipe of the appliance. A further possibility provides that portions of slowed down water are accelerated by supplying water at an increased flow rate. Suction of the portions of slowed down water as well as the supply of water at an increased flow rate is particularly effected through apertures in the bottom surface in the regions in which the portions of water are particularly slowed down, i.e. above all in the regions in the vicinity of an overflow at the upper end of the sloping bottom surface.Type: GrantFiled: May 23, 1983Date of Patent: January 14, 1986Inventor: Otto Frenzl

Patent number: 4563401Abstract: An electrochemical cell of the type characterized by an essentially constant operating voltage essentially independent of the degree of cell discharge is disclosed, which in its output voltage exhibits one or more step changes of predetermined and fully adjustable magnitudes at any predetermined point or points during the life of the cell. This enables timely replacement of the cell under non-critical circumstances, and also can be used to indicate state of discharge of the cell. In essence, the anode of the cell comprises a plurality of anode elements which become depleted at mutually different degrees of cell discharge. As each anode element becomes depleted, the internal resistance of the cell increases to cause a drop in the operating voltage of the cell as the remaining active anode elements are required to supply the required current.Type: GrantFiled: December 24, 1984Date of Patent: January 7, 1986Assignee: Battery Engineering, Inc.Inventors: Philip F.

Patent number: 4561962Abstract: The invention concerns an ion-selective electrode comprising a polymer membrane, and its manufacturing procedure. Selectivity of the electrode to a given ion has been achieved in that the membrane is of material polymerized from a substance or mixture of substances containing the ion in question and from which after the polymerizing step a quantity of ions of this kind has been removed so that gaps of equivalent size have been produced in the material. An example of said polymerizable substances is a mixture formed by allyloxy-substituted propyleneglycol phosphate and calciumbisdiallyl phosphate, which is used in making a calcium-selective electrode. If in the example mixture calcium is replaced by another ion, an electrode which is sensitive to this particular ion is similarly obtained. It is to advantage in view of the electrode's mechanical properties to make the electrode without internal solution by affixing the polymer membrane directly on the surface of a semiconductor body consisting e.g.Type: GrantFiled: December 14, 1984Date of Patent: December 31, 1985Assignee: Fluilogic Systems OyInventor: Jouko Kankare
