Title: Circuit for encoding and decoding teleprinter communication data - reduces multiple pulse codes to two variable length pulses
Inventor: DIRR JOSEF ING GRAD
IPC: H04L25/48
Filed: 1979-09-25
Abstract: A transmitting station and a receiving station or intermediate exchange each have an oscillator of the same frequency, which serves a common gauge for producing pulses of a well defined length. Each signal is represented by a combination of only two pulses of accurately defined lengths, separated by a pause of a defined length. In a receiving unit these two pulses are evaluated without error because allowance is made for minor length variations. An example for a receiving circuit comprises an oscillator, a Schmitt trigger, a start switch operated by loop interruption in an optoelectronic relay, bistable flip flops, BCD counters and logic gates. The combined outputs of the counters results in a unique signal identifying output which is then temporarily latched.

Title: Tape activating control for video recorders - uses rapid sequential change in magnetic tape transport direction, with specified recording during forward run
Inventor: ZAHN HEINRICH
IPC: G11B5/02
Filed: 1979-12-22
Abstract: The video tape energising is carried out during the reproduction of video tape recorders. The signals, corresp. to the image to be reproduced, are written in an image memory and read out repeatedly from it. After signal storage, the magnetic tape is moved in opposite direction and arrested in a position, from which the magnetic tape can reach the required velocity when the forward run is again operated. The velocity provides a certain number of images in front, or behind, the image stored in the memory. The change between the two transport directions of the magnetic tape follows in a rapid sequence. During a forward motion a recorded standard signal is reproduced, followed by recording of a standard signal. Pref. the recording and reproduction are carried out by different transducers. In the following forward motion phase the transducer function may be exchanged.

Patent DE-3027046-A1 (DE)
IPC: B28B15/00
Filed: 1980-07-17
Abstract: In the method of manufacturing prestressed concrete sleepers on a prestressing bed, the form moulds, in which the prefabricated parts are moulded in production stations (A, B, C), are moved, after the compaction of the concrete of the respective prefabricated part, from one production station to the production station which follows in the direction of production. In this case, for manufacturing the prefabricated parts, in addition to the number of form moulds necessary for in each case one production operation in one production station, at least one further set of form moulds is used and the form mould (20) used for manufacturing the prefabricated part at the production station (C) lying at the rear in the direction of production is only freed from the latter and removed when the concrete of the prefabricated part which is being manufactured at the adjacent production station (B) is completely compacted and this form mould (20) is subsequently brought to the production station (A) which follows in the direction of production. As a result, it is brought about that, while the prefabricated part which in each case is the next to be manufactured is compacted by vibrating, the previously manufactured prefabricated part is not damaged by the vibrations which are conducted further in the prestressing wires, but that there is even an intensification of the bonding of the prestressing members (2) with the concrete surrounding them. <IMAGE>

Patent DE-3032578-A1 (DE)
Inventor: KOLITSCH JOERG DIPL ING
IPC: G01F1/28
Filed: 1980-08-29
Abstract: Method for the dynamic and density-independent determination of the mass flow of fluids. A single vortex generating bluff body is placed in the flow to generate vortices according to the principle of the Karman vortex path. The dynamic pressure (1/2 rho v2) is determined via the effect of the drag directly at this bluff body. The velocity of flow (v) is determined via the effect of the vortex shedding at the bluff body. The mass flow is determined according to the equation: m=2x(1/2 rho v2)x1/2xA wherein A is the cross section of the flow channel. Device for implementing such method. The device consists essentially of a vortex-generating bluff body having one or two fixed ends, which itself serves as a transducer or at which one or two transducers are provided. An electronic system for processing the resultant signal is available.
