Title: Variable volume reciprocating metering pump - has axially adjustable cylinder housing to vary cut off point of delivery (NL 28.9.77)
Inventor: SCHMID ALFONS ING GRAD
IPC: F04B43/067
Filed: 1976-03-26

A housing attached to the main frame has a circular section with a screw thread on the inside and a chain wheel drive on the outside. The chain wheel is turned by a servo motor. A cylinder housing (39) with an external thread fits inside the circular section (31) so that when the circular section is turned the cylinder housing moves axially. The housing contains the cylinder (41) in which the piston (43) reciprocates. The cylinder has an opening (45) which releases the pressure when the piston uncovers it and this point is varied by the axial movement of the cylinder.
Patent DE-2613959-A1 (DE)
Inventor: WOLF HORST DIPL ING
IPC: H02H7/085
Filed: 1976-04-01
Abstract: The synchronous or asynchronous motors (6) are connected to a three-phase network (4) in the case of said three-phase network having a low frequency, and are accelerated when the network frequency increases. In order to reduce the protection complexity, the individual motors (6) are protected by fuses (14), dispensing with motor protection circuit breakers in their phase supply lines. The operating current of said fuses (14) corresponds to 1.05 to 1.2 times the respective motor rated current. The current consumption of the motors does not exceed these operating values in the connection phase and acceleration phase. The simplified overload protection circuit is particularly suitable for use in the case of a draw-twister machine. <IMAGE>

Title: Radially contracting pipe valve - has elastic sleeve located inside rigid housing bush by expansion rings
Inventor: LESK ADOLF
IPC: F16K7/07
Filed: 1976-04-12
Abstract: A constrictor pipe valve includes an elastic sleeve (1) which is located inside a coaxial rigid housing (2). Internal radial grooves in the housing bush (2) are provided so that expansion rings (3) are able to clamp the two ends of the elastic sleeve (1). The ring chamber which is formed by the elastic inner sleeve and the outer housing bush (2) is connected to a pressure source by means of fitting (7). In order to stop or to reduce the flow in the pipeline, the ring chamber is pressurized. This causes the elastic sleeve (1) to contract such that its inner cross sectional area is reduced or is nil, thus regulating the medium flow.

Title: Electromechanical pen recorder with analogue and digital indicators - controls chart by comparator responding to error signal with counter coupled to disc
Inventor: SCHLEBAUM KAREL HENDRIK
IPC: G01D9/34
Filed: 1976-08-06
Abstract: Pen recorder for currents or voltages with analogue and digital recording. The system will record both analogue and digital information on the same diagram. As the coded digital signal will be scanned, this means that the width of the scale will not be critical in the processing. The infinite recording tape is transported at a constant speed and the pen or printout elements for the analogue and the corresponding digital recording are located at regular intervals. The recording chart is controlled during the analogue recording by a comparator, which responds when the input signal is equal to a variable comparator signal. This signal is derived from a pulse circuit derived from a position counter coupled to a coding disc.
