Patent DE-3443797-A1 (DE)
Title: Process for producing a plate having a fluid-line system formed to one side
Inventor: RICHARD ROBERT
IPC: B21D26/059
Filed: 1984-11-30
Abstract: In this process, two metal sheets are laid one above the other and are welded to one another on their entire contact surface, with the exception of regions in which the formation of lines of a line system is provided. The line system has a closed outer line and an inner fluid-line system which are connected to one another by means of at least one connecting line. The plate formed from the sheets welded together is introduced into a press, in which the outer line is expanded by means of a pressure fluid, until it sealingly closes off a volume between the press jaws of the press. One side of the plate is subsequently subjected to pressure, and the connecting line or connecting lines of the inner fluid-line system are expanded. The process is characterised in that the flow resistance of the connecting line or connecting lines is designed so that, at a constant pressure of the pressure fluid, the plate is subjected to pressure after the outer line has been expanded and before the expansion of the inner fluid-line system takes place. 
<??>This process is simpler and very much more reliable than conventional processes and, furthermore, requires only presses of lower power.

Title: Ergonomic line-engraving apparatus
Inventor: LORKOWSKI CHRISTA
IPC: B44B11/02
Filed: 1984-11-27
Abstract: The apparatuses which have been used hitherto have two particularly striking disadvantages. Due to the cutters always being positioned vertically, it was not possible to have an accurate view of the cutter tip. The position of the legs with respect to the cutter and the resulting "T"-shaped or triangular basic form did not permit individual guidance of the cutter on the rule, and "mobility" for engraving sharply curved lines was thus not provided. In the case of the present apparatus, the cutter/legs relationship was selected such that legs no longer bear on the rule, but solely the precise positioning of the cutter on the engraving foil is thus achieved. As a result of the novel outline and the selected inclination of the cutter with respect to the left-hand outer edge, said cutter can be clearly seen jutting out therebeneath and the chisel-shaped, fixed cutter can be applied accurately at any point without difficulty.

Title: Electronic flash apparatus having a series controller
Inventor: NAKAMURA HIROAKI
IPC: H05B41/32
Filed: 1985-01-03
Abstract: An electronic flash apparatus having a series controller is created, which apparatus has a series circuit consisting of a discharge tube for the flashlight and of a main thyristor, which circuit is additionally also connected in series with a thyristor which forms a reversing charging path for a commutating capacitor. The series circuit consisting of the discharge tube, the main thyristor and the last-mentioned thyristor is connected in parallel with a main capacitor. A diode is connected in series with the commutating capacitor such that this series circuit is connected in parallel with the thyristor, for charging in the reverse direction. This thyristor for charging in the reverse direction becomes conductive when the main thyristor is switched on, in order to produce a reverse charging path for the commutating capacitor when it is intended to carry out a commutation operation. This prevents charging current or blocking current blowing in the reverse direction to the commutating capacitor, through the discharge tube for the flashlight. In consequence, exact control of the extent of illumination by the flashlight is possible. <IMAGE>

Title: Clock case with an aperture frame
Inventor: SCHULTHEISS UDO
IPC: G04B37/00
Filed: 1985-10-17
Abstract: A clock case with a carrier plate which is surrounded by an aperture frame and is intended for the clockwork and minute wheel work is to be designed in such a manner that despite very different clock shapes depending on the selected viewing side of the clock case the complexity in terms of production with regard to individual parts to be provided and assembly requirements is reduced. For this purpose, on each of its surfaces the carrier plate has aperture frames of different configurations which protrude approximately axially parallel, surround the clockwork radially on one side and on the opposite side determine the geometry of the clock face. In each case depending on which side of the carrier plate is equipped the result is a clock in which either a relatively small clock face is surrounded by a relatively wide case boundary surface or in which a large clock face surrounded by a narrow front face dominates.

Title: Automatic silo water power station
Inventor: WUERTH GUSTAV DR
IPC: F03B17/02
Filed: 1986-01-20
Abstract: The automatic silo water power station consists of a recirculating mechanism resembling an elevator, which is installed in a water silo and on whose recirculating roller chains or the like horizontally situated cylinders are mounted at regular intervals. Located in each cylinder is a movable piston which divides the cylinder into an air space located at the front and an open water space situated behind the piston. A strong spring of appropriate length is accommodated in the air space. This spring can be biased by means of a cable line, driven by an electric motor, or the like by pulling the piston to the cylinder head. In this state, the air space is at its smallest and the displacement of water at its slightest. This state is brought about in each case at the upper turning point. The cylinder is thus guided downwards with the slightest water displacement. At the lower turning point, the spring is detensioned and then presses the piston outwards, resulting in the formation of an additional air space. The cylinder thereby starts to rise, and as rising proceeds the water pressure on the piston is continuously reduced, with the result that the piston can slide further outwards and enlarge the air space. The spring is then detensioned again at the upper turning point and can be biased again. As the air space is enlarged, there is also an increase in the flotation energy, since the empty weights of the rising and falling cylinders neutralise one another. The flotation energy can...

Title: Highly flexible shaft coupling
Inventor: BOEHM HEINZ-DIETER DR ING
IPC: F16D3/74
Filed: 1986-07-15
Abstract: A description is given of a highly flexible shaft coupling in which the coupling halves are connected to one another via at least two annular arrangements of rubber-elastic coupling bodies arranged axially in series. One of the annular arrangements consists of coupling bodies with a V-shaped cross-section and an annular arrangement adjacent to the first-mentioned arrangement consists of coupling bodies which comprise rubber-elastic elements which are vulcanised at their inner and outer circumference to cylindrical rings. This configuration provides the advantage that the axial displacements which occur when the V-shaped coupling bodies are deformed can be absorbed by the adjacent, differently designed coupling bodies. An adequate angle of twist is nevertheless achieved by the addition of the angles of twist of the two types of element. By appropriate structural design, good ventilation of the coupling parts is also ensured.
