Title: Incubator, in particular for the polymerase chain reaction
Inventor: FRH V GISE HARDO DR MED
IPC: B01L7/00
Filed: 1988-03-17
Abstract: The invention relates to an incubator (10) which is provided, in particular, for the polymerase chain reaction (PCR). The incubator (10) is provided with at least two reservoirs (14) of which each contains a liquid (16) which can be set to a defined temperature.

Title: Worm-type reaper
Inventor: WIENEKE FRANZ PROF DR ING
IPC: A01D34/52
Filed: 1988-06-06
Abstract: Worm-type reapers, especially with a toothed cutter, tend to recut and shorten the stalk crop.

Patent DE-3828752-A1 (DE)
Title: Electronic spoiler adjustment controlled by travel parameters and using drive units on land vehicles
Inventor: ZIFFER ARMIN
IPC: B62D35/00
Filed: 1988-08-25
Abstract: The electronic control of spoilers on land vehicles is used to provide a vehicle with constant optimum stabilisation as a function of travel parameters, i.e. always to ensure an optimum position on the road. All the travel parameters (speed, acceleration, braking and cornering) which are important for a suitable attack angle of spoilers are transferred by measurement sensors to an open-loop and closed-loop control unit and processed in order to obtain an appropriate attack angle for the spoilers. This attack angle is then set at the spoilers by means of the drive units.

Patent DE-3843826-A1 (DE)
Title: Silencer
Inventor: SCHUELE PETER
IPC: F01N1/10
Filed: 1988-12-24
Abstract: In a silencer for the damping of sound waves generated by internal combustion engines an inner pipe (11) is arranged in a casing pipe (10). The space (14) between casing pipe (10) and inner pipe (11) is filled with sound-absorbing media. Silencing occurs due to reflection on the transitional surface between inner pipe (11) and the sound-absorbing media. By means of a deformation of the inner pipe (11) into a pipe of polygonal cross-section with sides (11b) deformed into the interior of the polygon, an enlargement of the transitional surface is achieved, which makes enhanced silencing possible but nevertheless only slightly reduces the engine power output. <IMAGE>

Title: Projectile arrangement
Inventor: PAHNKE KLAUS-DIETER DIPL ING
IPC: F42B12/06
Filed: 1989-01-17
Abstract: The invention relates to a tandem projectile arrangement which is mechanically coupled by means of cable. In the case of known tandem projectiles, the fastening of the cable ends requires costly (complex) and space-consuming designs in order to absorb cable extension shock. A space-saving cable end fastening which reliably absorbs the cable extension shock occurring is proposed according to the invention. To this end, recesses (30, 32) which expand conically and are on the central axis are provided in the rear part (24) of the front flying body (10) and in the nose part (26) of the rear flying body (12), in which recesses (30, 32) the spliced-on and knotted fibres of the cable ends (34, 32) are wedged and securely fixed by means of a potting resin or a metal alloy which is poured in in the melted liquid state. <IMAGE>

Patent DE-4012433-A1 (DE)
Inventor: ROTH PAUL DIPL ING
IPC: B05B12/00
Filed: 1990-04-19
Abstract: The throughput control of liquids is usually carried out with devices which operate according to the suspended solid particle principle, with turbine wheel counters, with impact plates or, for example with shutters. Here, solids in the liquids in the measuring devices can lead to blockages and/or contaminations. Furthermore, the measuring devices can only be cleaned with difficulty. In order to be able to monitor the throughput of the active substance fluid through the discharge line in a simple manner over a relatively long period of time without there being a risk of blockages, the liquid level (18) in the active substance tank (1) can be controlled by at least one monitoring element. When the liquid level (18) drops below a predetermined level, a sound signal is transmitted to a rinsing device (15, 16, 17) for automatically rinsing at least a part of the discharge line (3). As a result, the active substances located in the active substance fluid are easily prevented from being precipitated in the discharge line (3) leading to contaminations or furring. <IMAGE>
