摘要： The invention concerns an apparatus and method for ultrasonically testing thick-walled workpieces at an increased scanning speed by the use of a plurality of ultrasonic test probes wherein the probes are selectively rendered operable. The transmit probes are temporarily inhibited from transmitting search signals into the workpiece for a time interval during which the receipt of a defect responsive echo signal by a receive transducer is anticipated. The scan frequency is determined therefore by a clock circuit and the transmission of search signals is halted only temporarily for a brief period during which time there is no skipping in the predetermined transmitting sequence of the transducer probes.

摘要： A control device for the coolant and heating circulation circuit of an internal combustion engine having a radiator, a feed pump, and a heat exchanger. The control device includes a rotary slide valve arranged in a valve housing. The rotary slide valve has at least nearly a sleeve shape and is provided with an axial collector opening for the feed or removal of coolant to or from the intake or delivery side of the feed pump. Provision is made in the circumferential wall of the valve housing for inlet or outlet openings for a bypass-circulation line of the coolant, for a radiator line connected to the radiator, and for a heating line leading to the heat exchanger of the heating circulation circuit. The rotary slide valve has, in its circumferential wall, a control opening having an opening through which a connection is established from the collector opening to one individual inlet or outlet opening or, for a mixed operation, through which an overlapping connection is established to two adjacent inlet or outlet openings.
