Abstract: Method and arrangement for control of a brushless alternating current motor 23 which is driven by an inverter 31-36 connected to a direct current source 24, 25. The direct current that is supplied to the inverter is detected. The signal is taken across a peak-value detector 41 to a regulator 45 which decreases its frequency-control output signal if the peak-value input signal exceeds a predetermined value. A control signal corresponding to the motor's momentary requirement is also created. This signal controls the voltage supplied to the motor. Negative pulses arising when the inverter switches are closed are also detected and used to control the degree of magnetisation of the motor. <IMAGE>

Abstract: An electronic postal meter has a control unit, an accounting unit and a printing unit, each incorporating a CPU having a separate crystal controlled clock. Communication between the units is serial character asynchronous, bit synchronous, in message form, with the bits of the messages being timed in accordance with a given schedule for synchronous control. The messages themselves, upon receipt by a receiver, are returned bit by bit to the transmitter, for checking, whereupon the transmitter sends a no-error pulse upon successful comparison of the transmitted message and the message received from the receiver. All control and data signals utilize the same pair of conductors in each direction with precisely defined timing for control.

Abstract: Teat cups are linked to a receptacle which feeds via a choke into the vessel coupled to a vacuum. The teat cup vacuum can be raised during milking above a first level or lowered below a second level by a control block with mode indicator. Between the receptacle (7) and choke (8) the milk line (6) contains a hydropneumatic transducer (15) linked to a membrane comparator (32-35) control block (12) to convert milk line pressure to a pneumatic signal output. The output is fed to the block input (16). A first output signal (13) is formed when the pneumatic signal reaches a first preset level due to milk production rising to the first preset level, and a second control signal for reduction in pneumatic signal due to production falling below the second level. In series with the transducer and parallel to the choke linking the transducer to the vessel (9), when production falls below the first level, is a slave valve (17) to link the transducer to the vessel, when production rises above the first level.

Abstract: An internal combustion engine includes a cylinder head having attachment surfaces which lie in the same plane and to which a head cover and an intake manifold are attached, respectively. The attachment surfaces can therefore be machined simultaneously in one process with a common cutting tool. The internal combustion engine also has a valve operating mechanism housed in a valve mechanism chamber in the cylinder head for actuating intake and exhaust valves. The valve mechanism chamber is defined by a pair of opposite trapezoidal end walls extending from the bottom of the valve mechanism chamber and a ceiling wall integrally interconnecting the upper ends of the trapezoidal end walls. The valve mechanism chamber has a pair of windows defined one on each side of the ceiling wall thereof between the trapezoidal end walls to provide access therethrough to the valve operating mechanism.

Date Feb. 25, 1988.A process for manufacturing potato fibers and potato fibers manufactured in the process. According to the process, potatoes are subjected to washing, dividing into potato juice, starch and pulp, and subsequently separating of starch from potato juice and pulp. The process is distinguished in that solid impurities are removed from the pulp, potato juice being defoamed and added to the pulp to form a pulp/potato juice mixture which is relieved of solid impurities by density separation. Subsequently, the pulp is dewatered to remove part of the potato juice, and the dewatered pulp is refined such that the content of potato juice and dissolved salts in the pulp is reduced in that the pulp is prepressed to a dry solids content of 20-30% and thereupon washed by adding water to obtain a dry solids content of 11-16%, whereupon the pulp is finally pressed to a dry solids content of 20-30%. Finally, the refined pulp is subjected to drying and grinding to the final potato fiber product.
