Patent DE-3608499-A1 (DE)
Title: Electrical energy transducer (converter)
Inventor: SCHMID MICHAEL
IPC: H02N11/00
Filed: 1986-03-14
Abstract: An electrical energy transducer for converting electrical energy into mechanical energy and vice versa, using the interactions between electromagnetism and gravitation. An electrical energy converter, characterised in that electrical energy is supplied into an electrical or magnetic field in order to produce a dipolar gravitation field. The respective secondary field is produced depending on the type of the primary field into which the energy is supplied. Both fields have the same intensity (1 : 1 ratio) when the linking factor reaches its maximum value. The linking factor of both fields reaches this maximum value when the energy which is supplied reaches the magnitude of the threshold energy. In the case of energy being supplied beyond the threshold energy, the linking factor maintains its maximum value. Main possibilities for use:     - acceleration of masses - drive systems for aircraft and space vehicles as well as for electrodynamic suspension tracks (magnetic levitation tracks) and electrodynamic suspension rail vehicles   - deflection systems for reducing aerodynamic drag - braking of masses and conversion of kinetic energy into electrical energy   - conversion of thermodynamic energy into electrical energy - enclosure of thermochemical and thermonuclear reactions in reactors.   <IMAGE>

Title: Vibratory drive
Inventor: DITTMANN PETER
IPC: B06B1/16
Filed: 1986-04-04
Abstract: A vibratory drive for concrete block moulding machines has a drive shaft (2) which can be driven by a drive motor (25) and has an internal unbalance mass (3) and, mounted on said drive shaft (2), a cylindrical rotation body (5) with an external unbalance mass (6) and two stops (10 and 11). The drive shaft (2) is mounted, outside the rotational body (5), on a base plate or vibration plate (15). With full drive of the drive shaft (2), the internal unbalance mass (3) assumes a position determined by the first stop, in which it doubles the effect of the external unbalance mass (6). When the drive is switched off, the internal unbalance mass (3) assumes a position bearing against the second stop, in which the resultant unbalance is compensated to zero. To effect a very rapid start-up of the vibratory drive after switching off, the invention provides a control circuit (35) in the electrical circuit of the drive motor (25), which controls said drive motor (25) just such that the rotational speed of the drive shaft (2), and thus of the vibratory drive (1) does not decrease to below 80% of the nominal rotational speed in the operating position. The rotational speed is regulated slowly and smoothly back up to the nominal rotational speed such that the internal unbalance mass (3) does not leave the compensation position with respect to the outer unbalance mass (6). In the rest position, the vibratory drive can also be prevented from falling to below 80% of the nominal rotational speed by driving the external rotational body (5) by means of a further rotational motor. <IMAGE>

Title: Energy generation from deep-mining systems with decentral heat exchangers
Inventor: NASSER GAMAL EL DIN DIPL ING
IPC: F03G7/04
Filed: 1986-10-23
Abstract: All heat quantities occurring underground which originate from the rock heat, the heat emission from the material to be conveyed, the heat emission from electrical operating media and the heat of compression are first of all delivered to the air flow and heat the air flow up to 50@C and even higher at increasing depth. At a depth of 1500 m, for example, a rock temperature of 60@C can be expected. It is known to set up heat exchangers to create a tolerable climate for the miners, e.g. near the working faces. The heat exchangers cool the mine air by means of cooling water. According to the invention, it is now proposed to set up as many heat exchangers as possible for the generation of energy in the entire mine layout, preferably near to the faces. In the heat exchangers, heat energy is delivered from the air flow to a cooling medium. The return of the cooling medium from the individual heat exchangers is collected and delivers its heat content to an energy transfer agent, as described in the main application P 3621393.4, at one or more decentral locations.

Title: Subtraction circuit in 5211 code
Inventor: MERKLE PAUL
IPC: G06F7/50
Filed: 1987-08-26
Abstract: The subtraction circuit according to the subject of the invention is a true subtraction circuit, because it has a main circuit (2), which is a true subtraction circuit. This main circuit (2) processes only the value 2, because this reduces the size of the main circuit (2) to a quarter. The value 1 is processed in the dual full subtractor (6). The value 5 is processed in the dual full subtractor (7). Circuit (3) is a blocking circuit, which passes on only the high potential with the lowest value of the high potentials which occur in the output area of the main circuit (2). Circuit (4) is not a one-downwards shift circuit but a one-upwards shift circuit, because no possible subtrahend with the value 1 is processed using this circuit, but a possible partial minuend with the value 1 is processed. <IMAGE>

Title: Contact lens applicator
Inventor: SCHNEIDER PAUL
IPC: A61F9/00
Filed: 1988-07-05
Abstract: The invention relates to a device for placing contact lenses on the eye and removing them therefrom. The adhesive surface for retention of the contact lens on the device is formed by the flexible rubber diaphragm which can selectively be converted by the bellows pump to the concave state for holding or to a convex shape for releasing. At the same time, dry retention of the contact lens is possible if - as provided in an expedient embodiment of the invention - the rubber diaphragm possesses a passage opening for the reduced pressure to the contact lens, so that the contact lens is held by vacuum on the rubber diaphragm. In order to protect the mounted contact lens against impact from the eyelashes it is completely accommodated in the lens holder; thus, the contact lens does not project by its outer edge. The bellows pump for controlling the diaphragm shape is expediently fitted on the outer circumference of the thimble-like device holder, where it can be reached and actuated with the thumb.

Title: Method for producing printed circuit boards, device for producing printed circuit boards, and a printed circuit board
Inventor: MORCHE DIRK-WALTER DIPL ING
IPC: H05K3/10
Filed: 1988-07-01
Abstract: Printed circuit boards consist of a carrier material and a layer which forms the conductor tracks. Until now, a continuous copper layer has been coated, during production, with a photochemical material which is exposed, developed, and the printed circuit board surface subsequently etched. The known method is time consuming and not environmentally friendly. According to the invention, a substance is applied as the coating material which can be changed by a physical or chemical effect from an originally non-conductive state into a conductive state. The coating material is then subjected to the physical or chemical effect in the region of the conductor tracks to be produced.
