IPC: C12N15/31
Filed: 1983-09-03
Abstract: The treatment of tendamistat-producing strains of Streptomyces tendae with sublethal doses of acriflavine produces mutants which provide very much higher yields of tendamistat. In contrast to the initial strains, which harbour the tendamistat gene on a 4.7 kb Pst I fragment, in the mutants it is located on a 2.3 kb Pst I fragment. The gene is multiplied in the mutants by a factor of about 20.
Patent DE-3332539-A1 (DE)
Title: Tandem
Inventor: REICHMANN HELMUT DR
IPC: B62K3/12
Filed: 1983-09-09
Abstract: The invention relates to the seating position on a tandem. In order to enlarge the restricted field of vision for the rear rider, to make the vehicle more fun to use and to improve traffic safety, it is proposed to arrange the seating position of the second rider in such a way that he looks backwards ("Janus-tandem"). In order to maintain the conventional pedalling direction of the pedal drive, it is necessary to reverse the direction of rotation for the rear rider. As a result of the proposed seating position of the second rider, he receives a free field of vision which covers the blind spot of the first rider. At the same time, a more central distribution of mass is achieved which has favourable effects on the handling and the manoeuvrability and permits shorter constructional designs.

Patent DE-3346180-A1 (DE)
Title: Rigid thermal insulating body
Inventor: KUMMERMEHR HANS
IPC: C04B28/00
Filed: 1983-12-21
Abstract: In the hardening of a thermal insulating material based on microporous oxide aerogel such as silicic acid aerogel, material shrinkage occurs, which can lead to cracking in particular at points endangered by stress peaks. Such a cracking can be suppressed if reinforcing fibres with a length of more than 10 mm are added to the material in a proportion of more than 10% by weight, it being necessary in unfavourable isolated cases also to add a larger quantity of such long fibres. With an addition of 25% by weight of long fibres no more formation of cracks or even of fractures is to be feared. The flexural strength achieved by the hardening of the material is not impaired by the increased proportion of long fibres.

Title: Asynchronous and synchronous transmission of transformed data rates via digital networks with back transformation at the receiving end
Inventor: MARTIN HELMUT DR ING
IPC: H04N7/54
Filed: 1984-03-14
Abstract: The method serves to transform any given data rates through removal of redundant words or addition of words before transmission to match clock rates of digital networks. This is done synchronously in the case of direct transmission. In the case of multiplex formation with other data streams, the transmission may be carried out both asynchronously and synchronously. The method is suitable in particular for transforming data rates of digital colour television transmission for transmission via public networks.
Patent DE-3415525-A1 (DE)
Title: Automatic gear changes for toothed-wheel change-speed gears with two or more shifting members in permanent engagement
Inventor: FRANZ KASPAR DIPL ING
IPC: F16H3/10
Filed: 1984-04-26
Abstract: The invention represents a further development of a gear which has become known as the Maybach double overdrive gear, which had two shifting members in permanent engagement which were moved into one of the engagement positions or the other by pneumatically switchable tipping springs, the shifting members being replaced in a known manner by hydraulically actuable dog or multi-plate clutches in order to permit a rapidly and smoothly operating automatic shift. A structural innovation is the installation of a further pair of wheels, with the aid of which two additional gears can be selected. The tractive force is not interrupted during the gear change due to the installation of just two overrunning clutches (free wheels). The reversing gear on the output side, which can be shifted manually by means of a manual shift lever and is intended for idling, forwards and reverse travel, is retained, with the possible omission of the "emergency starting gear".
