Title: Drive for fully mixed bioreactors
Inventor: ETZOLD MICHAEL
IPC: C12M1/08
Filed: 1988-03-30
Abstract: Pulse drive (8, 9, 10) for fully mixed bioreactors for adjusting the circulation of a substrate introduced into the reactor container (1) with a pulse nozzle (10) whose inflow and outflow cross-section and/or inflow and outflow rates are adjusted in the intake and pressure stroke of the pulse cycles to achieve substrate circulation so that the vigorous mixing and circulation of the reactor contents take place without mechanically moved parts in the reaction volume for use in biological fermentation processes substantially without adverse effects on the active microorganisms, an optimal supply and discharge of the reaction components are guaranteed by the continuous renewal of the contact surfaces. The pulse drive also effectively counteracts possible channelling or formation of dead spaces and is equally suitable for sludge, fixed or fluidised bed operation even in reactors with packings. The pulse drive operates on the displacement principle and can contribute to reducing the energy consumption necessary for the process because new types of operating states with superimposed pulsation can be set up. <IMAGE>

IPC: C07H21/00
Filed: 1988-07-01
Abstract: A method of producing double-stranded nucleic acid derivatives having RNA as the parent body (the total molecular size distribution of which is from 4S to 13S expressed as sedimentation constant value of, alternatively, is such that the derivatives have base numbers in the range 50 to 10,000) including sizing nucleic acid polymers and subsequently combining them.

Title: Coupling device on double lock cylinders
Inventor: LAURENZ LOTHAR
IPC: E05B9/10
Filed: 1988-08-20
Abstract: The invention relates to a coupling device on a double lock cylinder (1) with a danger function, which coupling device has a coupling member (21), extending between the inner end faces of the two cylinder plugs (9, 10), with two coupling halves (22, 23) which are sprung relative to one another on a central shaft and which each have two mutually sprung components in the form of a loading part and of a coupling element and possess radially projecting wings (45) capable of being pushed into a groove in the locking-member hub middle wall. It proposes, for perfect functioning, especially without any tilting of components, that the loading parts (25, 26) be designed as cylindrical bodies which are guided axially in the respective associated cylinder plugs (9, 10) which possess central bearing recesses (29, 30) for the coupling elements (27, 28) having the wings (45). <IMAGE>

Title: Seal for contact zones of two or more sealing systems
Inventor: FRANKENHAUSER GEORG
IPC: F16J15/40
Filed: 1988-08-30
Abstract: The object is to provide a seal which, in addition to sealing off the volume to be enclosed, also guarantees reliable separation of parts of the sealing system in which different sealing media which must not come into contact have been used. In the region of the contact zone between the grooves (3, 4) carrying different sealing media, one of the two grooves (3) is widened to a, preferably cylindrical, cavity (5), and the mouth (6) of this groove (3) is comprehensively sealed by means of a rubber pad (8) which is pressed on by means of a ram (9). The second groove (4) opens into the cavity (5) in the vicinity of the side opposite the mouth (6) of the first-mentioned groove (3). As a further development, the invention can also, and in particular, be used with advantage in contact zones between more than two sealing media. Sealing systems of the type described are found, for example, in the casings of hydrogen-cooled turbo generators, which are generally sealed, inter alia, with a viscoelastic composition and oil, where contact between the sealing media mentioned must be prevented. <IMAGE>

Patent DE-3839662-A1 (DE)
Title: Sewing machine with a thread-guiding needle movable to and fro
Inventor: HAGER WALTER
IPC: D05B55/14
Filed: 1988-11-24
Abstract: The object is to eliminate or at least mitigate known sewing difficulties, such as the sagging of the sewing material during pricking, tension curling, thread wear and the occurrence of faulty stitches. To achieve the object, it is proposed to connect the needle for rotation to a control device, in such a way that, before pricking, it is rotated out of the normal position with the needle eye pointing in the thread-feed or thread take-up direction (direction of advance of the sewing material), so that the thread tension can be reduced during the downward movement back to the normal position and beyond rotatably opposite the direction of rotation of the gripper and movably upwards into the loop-receiving position of the needle and gripper, in order to reduce the pricking force of the needle and therefore the sagging of the material and to move the needle-thread loop towards the gripper and thereby increase the reliability of the grasping of the loop. The direction and amount of the needle rotation can preferably be controlled in dependence on the direction of displacement of the sewing material. The control can be carried out by a sensor monitoring the tilting of the loop, via a stepping motor, in a simple version via a cam-slot/guide-pin arrangement. The subject of the invention is used in sewing machines. <IMAGE>
Patent DE-3840206-A1 (DE)
Title: Continuous rotational drive
Inventor: VAIC HELMUT
IPC: F01C1/356
Filed: 1988-11-29
Abstract: By means of the continuous rotational drive a high torque and an immediate reversal of the direction of rotation is achieved at a continuous, low speed of rotation. The advantage lies primarily in the fact that a constant, endless rotation exists in contrast to existing types of drive. For the drive, both pneumatic and hydraulic media are feasible.

Title: Device for the variable timing of the same type of lift valve for each combustion chamber of an internal combustion engine
Inventor: SEIDL JIRI
IPC: F01L1/14
Filed: 1989-02-16
Abstract: In the case of a device for the variable timing of the same type of lift valves for each combustion chamber of an internal combustion engine, a camshaft has three control cams, the outer control cams acting separately on the lift valves by means of transmission elements, and, for changing the timing, the two transmission elements being lockable via an intermediate element, cooperating with the central control cam. Due to the deviating contours of the central control cam the intermediate element undergoes a relative lift with respect to the transmission elements, and in conjunction with the relative lift of intermediate element and transmission elements, stops, which are arranged opposite one another and are spaced apart when the relative lift is at its maximum limit, serve for the purpose of introducing lift-blocking elements, which are subjected to compression by a locking device, between the transmission element and the intermediate element, in the base-circle phase thereof, for the mutual locking of the transmission elements above the intermediate element so that the same type of lift valves are operated jointly via the central control cam.
