Title: Paddle blade with improved hydrodynamic thrust
Inventor: JUERGENS DIRK DIPL ING
IPC: B63H16/04
Filed: 1993-01-08
Abstract: The paddle blade uses the hydrodynamic thrust generated by the blade cross-section as it is pushed through the water. To prevent water flow running longways down the blade ribs (1) are set across the thrust face of the blade at an angle parallel to the optimum water flow.The ribs can be of varying length and height depending on the application while the paddle cross-section has an appropriate hydrodynamic shape.

Patent DE-4302566-A1 (DE)
Title: Process and apparatus for the packaging of articles in net bags
Inventor: FRITZ ERWIN
IPC: B65B9/15
Filed: 1993-01-29
Abstract: The packaging apparatus consists of a pipe (1) which carries an axially gathered tubular net stock on its outer circumference. A conveyor band (12) extends through the pipe (1). In order to package delicate packaging articles (14), such as, for example, fruit, carefully in net bags, provision is made for the net, previously closed at its front end, to be stretched out essentially horizontally counter to the effect of a net brake (17) by extendable tensioning arms (15), before the packaging articles (14) are thrown into the net (2, 16) by the conveyor band (12). The packaging articles (14) which have sprung off from the tensioned net (16) then come to rest gently on a depository (20). So that they need not be thrown far when they are thrown off horizontally into the net (16) and so that they do not fall onto a clip head (18) serving as a retaining device when the net is tautened around the packaging articles (14), the pipe (1) is movable in the longitudinal direction over the clip head. <IMAGE>

Title: Electrokinetic device
Inventor: AUMEIER GERHARD
IPC: G01N27/447
Filed: 1993-03-12
Abstract: The electrokinetic devices which have become known so far, for separating molecular mixtures of substances into their individual components under the influence of an electric field, consist of a separating chamber having a cooling plate to which carrier gel is applied in the form of a film, and of a separately fitted cooling unit and a likewise separately arranged high-voltage section. Working with the known electrokinetic devices involves drawbacks. The object of the novel electrokinetic device is to provide for simpler operation while, at the same time, permitting improved resolution and reproducibility of the electrophoresis results without significantly increased outlay in terms of equipment. The electrokinetic device (1) according to the invention has, in addition to a cooling plate (4) made of metal, a bearing layer (2) in particular made of ceramic, to which the carrier medium containing the mixture of substances to be separated can be applied and which has such a relatively small thickness (d) as to ensure a still adequate electrical insulating resistance, the bearing layer (2) at the same time having such a specific conductivity that a high heat flux density in the direction perpendicular to the surface of the bearing layer (2) is ensured. The electrokinetic device (1) according to the invention is suitable for numerous electrophoretic applications. <IMAGE>

Title: Operation of a load circuit with load recognition
Inventor: PUESCHEL SIEGFRIED
IPC: G01R31/00
Filed: 1993-09-15
Abstract: The invention relates in each case to a method and a circuit for recognition that the load circuit has been switched on and for operation of the same, the load circuit being supplied from a DC voltage source. The moment of switching-on can be detected by continuously monitoring the amplitude and/or frequency of a high-frequency AC voltage which is produced in the load circuit, since the AC voltage parameters change suddenly at this moment. The monitoring can preferably be carried out by means of a filter such as a high-pass filter. One application according to the invention comprises the operation of a load circuit which is supplied with DC voltage from a voltage converter. The voltage converter does not start to operate until the fact that a load has been switched on, that is to say the load circuit is made, has been recognised as described above. Alternatively, the operating switch of the voltage converter can also be switched on simultaneously via a direct operative connection, by means of a load interrupter switch, when the load circuit is made. In particular, only a suitable combination of loads can always remain switched on by means of a load rejection circuit. This leads to energy savings and avoids costly electronic components and wiring systems.

Patent DE-4408488-A1 (DE)
Inventor: EITRICH FRANK-THOMAS DIPL PHYS
IPC: B60R16/02
Filed: 1994-03-14
Abstract: The invention concerns a method for cyclically transferring data between at least two separately operating control apparatus. The method is used in particular for transferring synchronisation data between the control apparatus (10, 11, 12). The control apparatus (10, 11, 12) are interconnected by means of a serial bus (20). The control apparatus (10, 11, 12) each comprise a serial interface (17) and a computing/control unit (15, 18). A computing/control unit (15, 18) of one of the control apparatus (10, 11, 12) cyclically prepares data to be transferred by means of the serial bus (20). The data are transferred by means of a message via the serial bus (20). For this purpose, the computing/control unit (15, 18) of the control apparatus (10) sending the message places a transmission order for dispatching the message to the serial interface (17). The serial interface (17) then develops the transmission order. However, this occurs in such a way that, when the message is sent, it is not those data which were prepared when the computing/control unit (15, 18) placed the transmission order which are used but, instead, the data updated by the computing/control unit since the time when the transmission order was issued. In addition, further advantageous bus user stations are proposed for use in the above method.

Title: Torsion damper with progressive response for IC engine clutch
Inventor: AMENT NORBERT
IPC: F16F15/123
Filed: 1994-04-15
Abstract: The torsional damper comprises pairs of helical springs (8,9) one inside the other contained within openings in the friction surface rear cover and output plates (4,5,6) of a clutch plate (1). The springs dampen by compressing when torque is applied to the plate and allowing some rotation of the output plate relative to the other two plates.The end faces (13a,13b,14a,14b) of the openings in the output plate are shaped to be in contact with the ends of the outer spring (8) but have a gap between them (13c,14c) an the inner spring (9) when the clutch is disengaged. The additional stiffness of the inner spring only takes effect after some compression of the outer spring has taken place.
