Title: Data modem receive bit sync. analysis - has AND=gate fed by divider for counter analysis and subsequent scanning by second count source
Inventor: WINKELMANN HEINZ ING GRAD
IPC: H04L1/20
Filed: 1980-12-05
Abstract: A data modem is used for block or packet reception of transmitted data. The receive circuit incorporates a timing tolerance detector and bit synchronisation circuitry. The latter also performs error detection functions. After the input signal has passed through the input discriminator, low pass filter and threshold detector it is split so that one path feeds into a delay network and the other into the synchronisation circuitry. After passing through a differential circuit the signal is fed to an input of n AND gates. The other input to the AND gates is fed from a divider circuit which distributes an nxbit rate clock pulse at 1/n rate to the gates. The gates feed into counters through switches so that the counters can be interrogated from a second divider clock pulse source to ascertain their count.

Patent DE-3110804-A1 (DE)
Title: Method and apparatus for feeding samples to continuous preparative carrier electrophoresis
Inventor: LAMMEL BERND DR
IPC: G01N27/447
Filed: 1981-03-19
Abstract: In continuously operating carrier electrophoresis (Offenlegungsschrift 2,840,614), the carrier medium is moved in an electric field relative to a sample-feeding apparatus. The particles to be separated are applied in a fixed location to a point of the carrier medium, so that the carrier moves past the feeding apparatus. The particles to be separated move, on the one hand, in the direction of the electric field and are, on the other hand, taken along with the carrier medium. This results in a two-dimensional separation which is exploited for continuous running of the apparatus. A great difficulty in this method is the sample feeding. This difficulty is overcome by pumping the sample continuously into a small tube which is open towards both sides and which is placed vertically upon the carrier medium. The sample is then drawn into the carrier medium with the aid of an electric field. This apparatus has the advantage that the samples can be fed continuously and controllably. In addition, it is ensured that the sample is applied to the carrier medium within a limited area which is as small as possible.

Patent DE-3149646-A1 (DE)
Title: Method for the production of seamless steel tube
Inventor: NUMANO MASACHIKA
IPC: B21B23/00
Filed: 1981-12-15
Abstract: A description is given of a method in which a starting material is rolled and formed to give a steel tube by a procedure in which it is passed through a two-high Mannesmann plug mill (tube-piercing mill), a mandrel-type elongation unit having three rolls, a multiple-stand continuous tube-rolling mill with a fixed or locked mandrel bar and a calibrating unit or calibrating mill with a high degree of reduction in the sequence indicated. The calibrating unit is positioned in such a way on the delivery side of the tube-rolling mill that the tubular shell rolled out by the tube-rolling mill is taken (directly) by the calibrating unit, the latter pulling the rolled-out shell from the mandrel bar of the tube-rolling mill in such a way that a tensile stress is exerted on the length of tubular shell situated between the outlet of the tube-rolling mill and the inlet of the calibrating unit, while the rolling out of the tubular shell by the tube-rolling mill and the rolling out or calibration of the latter by the calibrating unit take place simultaneously. The relative amount of work performed by the plug or tube-piercing mill, the elongation unit, the tube-rolling mill and the calibrating unit are expediently fixed in such a way that maximum and efficient use is made of the advantages offered by the mills or units and that a high output and economy and a high degree of accuracy are guaranteed by the interaction between these mills or units.

Title: Oil scraper ring for internal combustion engines
Inventor: STEIN HERBERT DIPL-ING
IPC: F16J9/14
Filed: 1982-02-17
Abstract: The invention relates to a single-part oil scraper ring for internal combustion engines. It comprises a flat spiral spring, resilient in a circumferential direction and essentially meandering due to alternate indentations, with a U-shaped cross-section opening radially outwards. This ring is to be so designed that opening of the ring joint after insertion in the piston groove is prevented, thereby avoiding the risk of damage when introducing the piston into the cylinder. For this purpose a hook pointing axially inwards is arranged on each joint end of the ring. The two hooks are aligned in opposition and when assembled can engage behind one another. This prevents the joint ends from separating after assembly. The insertion of additional elements for connection of the two joint ends is no longer necessary.

Patent DE-3229139-A1 (DE)
Title: Method for the transmission of the chrominance signals in colour television
Inventor: DIRR JOSEF ING GRAD
IPC: H04N11/06
Filed: 1982-08-04
Abstract: In the NTSC, PAL and SECAM colour television system, the hue is coded by a phase angle of two alternating currents. Whilst the transmission is amplitude-modulated in the NTSC and in the PAL system, the SECAM system provides for frequency modulation. Time and again, phase errors occur in the transmitting and receiving devices and also on the transmission link. In the PAL system, such errors are compensated by complicated elaborate circuits. In the SECAM system, other errors occur due to the frequency modulation. The present invention avoids phase as a transmission feature. It transmits the quantities of hue and colour saturation digitally or by analog means by means of an alternating current. The error is not only avoided but bandwidth is also gained, particularly in the binary-coded alternating-current transmission.
