Abstract: Encoded digital information signals are magnetically recorded on a magnetic recording medium with the assistance of a magnetic head to which write current is supplied. As a function of the encoded information signals, a head change is carried out wherein the current applied to the magnetic head is changed from a first current value to a second current value and vice versa. After each head change, an amplitude of the write current is varied in stepwise amounts from the first or second current value, respectively, and wherein the number of steps depends on a chronological spacing of the head changes from one another. Distortions of resulting read signals are reduced given the method and apparatus of the invention.

Abstract: Hydrolysis of plant kingdom polysaccharides by treatment with SPS-ase preparations.SPS-ase is an enzyme adapted to hydrolyzing the water-soluble protein binding polysaccharide present in soy flour decomposed by use of conventional pectinases, which polysaccharide is believed to be widespread in plant kingdom substances. Treatment with an SPS-ase preparation can clarify juices, wines and beers, hydrolyze process wastes such as sugar beet pulp, pomace, and soy milk remanence, improve the digestability of silage, and reduce the viscosity of wort.

Abstract: An electrochemical electrode device comprising a tubular member having a bottom end adapted to be inserted into a liquid sample to be measured, and a top end which is closed by a cap member including electrical conductors by means of which the electrodes of the electrode device are connected to an outer cable. In order to facilitate the introduction of liquid or gel into an inner space defined within the tubular member as well as withdrawal of liquid or gel from that space, a longitudinally extending passage is formed within the cap member. This passage may be selectively opened and closed by means of a closure member which is received in a cavity extending transversely to and intersecting the longitudinal passage. The closure member is preferably in the form of a swingably mounted slide valve member or a rotatable cock member.

Abstract: When setting a write gap or a read gap to a recording track on a magnetic medium, an edge of the medium is selected as a starting point, proceeding from which the write and read means are displaced in fixed track spacings. Appropriate method steps are:(a) generating a write signal with the write means of a read and write system exhibiting a write and a read means;(b) moving the medium from the write means toward the read means;(c) executing a read operation with the read means which generates a read signal;(d) comparing the read signal to a reference value identifying the write signal; and(e) outputting a detector signal indicating the edge when the write signal has been identified.

Abstract: A wet-motor pump having the rotor and the bearings utilize the pumped liquid, whereas the dry stator chamber with the stator windings is separated from and sealed against the rotor chamber through a tube-shaped can. The ends of the winding wires extend freely outwards on one side of the stator stack of sheets such as through an opening in the motor housing to be connectable to electric connections of a connection box mounted on the motor housing. A power cable for supply of energy to the windings is inserted in the connection box. The ends of the windings are connected to winding terminals in the stator chamber. The winding terminals are connectable to contacts and a plug. The plug comprising a shaft surrounding and isolating the contact may be inserted through the opening in the housing and into the stator chamber. As a result, a pump is obtained whereby the electric connections between the ends of the windings and the connections in the connection box may be provided in a simple and quick manner.

Abstract: The invention relates to a valve assembly for a refrigeration plant of the kind used for controlling the flow of refrigerant from the evaporator to the compressor. The closure member for the valve unit is controlled directly or indirectly by a movable wall of an expansible chamber filled with a refrigerant medium having vapor and liquid phases. The pressure exerted by the vapor phase of the medium provides a bias in a valve opening direction which is directly related to the temperature of the liquid phase and is opposed by a spring bias in the valve closing direction. A heat transfer element such as a heating resistor in the liquid phase is heated or allowed to cool in a controlled manner by an external control unit. A temperature responsive sensor element in the liquid phase of the medium is part of a feedback system for the control unit which allows a selected temperature to be maintained in the chamber which results in a desired constant pressure in a valve opening direction to be maintained in a chamber.

Abstract: A self cleaning vapor burner for liquid fuel in communication with a combustion chamber. The burner includes an electrically heated evaporating tube.

Abstract: The invention relates to a hydrostatic steering control unit of the type having valving for an open center neutral position which bypasses pressurized fluid from the pump to the tank when in neutral. During a turning operation with a steering wheel the open center valving is caused to close and the pressurized fluid is directed to one side or the other of a servomotor which is connected to wheels to be steered. The open center valving includes orifices in relatively rotatable elements which are aligned in the neutral position and closed to effect the turning operation. Open center valving can be the cause of noise and cavitation and such valving herein is provided with slot shaped orifices and flat generally wedge shaped throttle passages to minimize the noise and cavitation problems. The throttle passages are defined by curved bounding surfaces having rectangularly shaped outlines.
