Patent DE-3825948-A1 (DE)
Title: System for detecting the activity of gene expression control elements
Inventor: WOLF HANS PROF DR
IPC: C12N15/65
Filed: 1988-07-29
Abstract: This invention comprises the possibility of investigating gene control regions by cloning the gene segment, which has been predicted by sequence analysis, in the vicinity of a part of the S antigen of hepatitis B virus (HBsAg) in such a way that this gene is transcribed under the control of the gene segment to be investigated. The HBsAg thus acts as quantifiable indicator gene for any desired control segment. A great advantage of this method is that the amount of the expressed indicator protein can be determined directly, without disruption and destruction of the cells, from the supernatant. This is achieved by deletion of the pre-S sequence, which is necessary for membrane integration of HBsAg, at the 5' end of the gene. It is possible in this way to measure the regulation of HBsAg expression over lengthy periods in samples from the supernatant without destroying the cells (11). This comprises a considerable improvement compared with the established CAT assay system (expression of chloramphenicol acetyltransferase) (6), which makes it necessary to disrupt the cells at a particular time in order to detect the total enzyme activity. Another advantage of the chosen indicator gene compared with others, such as interleukin-2, is that it is not a gene contained in the cell genome, which might lead to misleading results due to uncontrolled expression. By preparing constructs of various viral promoter sequences ... Original abstract incomplete.

Title: Adder circuit in 51111 code
Inventor: MERKLE PAUL
IPC: G06F7/50
Filed: 1988-09-19
Abstract: The adder circuit according to the subject of the invention differs from the adder circuit according to P 3714665.3 mainly in that it does not process decimal digits in 1-out-of-10 code and supply the result in 1-out-of-10 code, but processes decimal digits in 51111 code and supplies the result in 51111 code. Also, a square adder circuit is used as the main circuit, but it is smaller, because a possible carry is processed in circuit (3), which is a one-upwards shift circuit, which is combined with a straight-ahead circuit. The main circuit (1) consists only of 19 AND circuits (9) each with two inputs, and 16 OR circuits (10) each with two inputs. The value 5 is processed in the dual full adder (4). <IMAGE>

Title: Snow production unit using water atomiser nozzles
IPC: F25C3/04
Filed: 1988-10-24
Abstract: The production of snow in a coldroom at temperatures below zero by the known snow cannon has been unsuccessful until now. By the use of water atomisers which spray aerosols into the coldroom, a continuous transformation to powder snow is possible. The fineness of the snow can be varied by alterations in the water and air pressure ahead of the nozzles. Coloration of the snow is possible by admixture of dyes. By fully automatic control of all technical processes the production of snow and the generation of coldness can be programmed. The movement of air in the coldroom is draft-free and facilitates the stay of people. The movement of air is produced by a radial fan. The production of coldness takes place by direct evaporation. The air cooler can be located in or outside the coldroom.

Title: Development of the operating method of internal combustion engines which are designed as naturally aspirated piston engines (reciprocating or rotary piston)
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N13/10
Filed: 1989-02-22
Abstract: The patent application with its own reference lei N 88/8 is, in accordance with its designation, a development of the operating method of naturally aspirated piston engines and relates to 7 priorities (based on an earlier application filed at the German Patent Office). It extends, to multi-cylinder engines, the method depicted by the applicant in DE-OS 3700182 of an abrupt emission from the exhaust. In all engine combustion chambers this method uses means of gas exchange within the inserted fuel/air mixture to increase the air-loading degree to a level which hitherto has not been possible. The consequence is a new possibility for low-emission engine operation and a substantial increase in engine performance whilst, at the same time, reducing the size of the fuel metering elements.
