Patent DE-4210504-A1 (DE)
Title: Method for drive control for hydraulic press - blocks pressure medium flow to retraction cylinders after working stroke, to prevent return stroke
Inventor: PAHNKE MICHAEL
IPC: B30B1/32
Filed: 1992-03-31
Abstract: The method is for use with forming machines, esp. a hydraulic press or forging machine. The machine has pump cylinders, charged by a crank drive, and retraction cylinders, which are under pressure from permanently rechargeable accumulators. After a working stroke, the pressure medium flow to the retraction cylinders is blocked. This prevents return stroke, and pressure fluid is sucked from the low pressure vessel into the working cylinder of the forming machine. Working and pump cylinders (2,4) are connected via a conduit (3), which is connected to the low pressure vessel (7) via a nonreturn valve (6). A second valve (15) is located in a conduit (13), which connects the retraction cylinders (9) to the fluid accumulator (14)/low pressure vessel. ADVANTAGE  - Allows stroke displacement and longer overall strokes.

Title: Machine for reeling continuously fed plastic sheeting - has main contact roller plus cutter for sheeting, system to move wound reel out and fresh shaft into position, and drive for either direction
Inventor: CZASCHKE UWE
IPC: B65H19/22
Filed: 1992-04-25
Abstract: A winding machine reels up continuously fed plastic sheeting. It has uninterrupted feed of the sheeting to form a reel of desired dimensions on the shaft in the reeling station and this reel plus shaft is moved out of that station; synchronised with this a fresh winding shaft is fitted in position and similarly wound on to desired dimensions. The machine has a wide guide roller for the fed material, a contact roller for the drive of the reeling shaft(s) plus sheeting; this last roller can be driven in either direction; a device holds the winding shaft and moves fresh shafts into position; a cutter cuts off the finished reel from the fed sheeting; the winding station reels up on the shaft to form the finished reels. The feed station is above the contact roller at 12 o'clock whereas the reeling station is at 9 o'clock; the shaft holding device also transfers a shaft plus reeling sheeting to the reeling station, from the 12 o'clock to the 9 o'clock position, and then to the 6 o'clock position i.e. pivots about the axis of the contact roller; during reeling the contact roller rotates in one direction, whilst the plastic film concerned is fed in at its 12 o'clock position and brought out at the 9 o'clock position and the shaft holder is at 6 o'clock; the contact roller rotates in the opposite direction during winding, whereby the film is fed in at or above 6 o'clock and brought out at 9 o'clock, and the shaft holder is at 6 o'clock. The cutter is connected to the shaft holder and is located behind it (in the first winding direction); to bring a fresh winding shaft into position the holder plus cutter pivot from 6 o'clock in the same direction as the contact roller to 12 o'clock of the feed station, whereby at least one guide roller for the cutter moves between the direct-reeling (i.e. non-festooned) sheeting and the contact roller; if the contact roller rotates in the opposite direction, to apply a fresh reeling shaft the holder and cutter pivot in the same direction as the contact roller from 6 o'clock to 12 o'clock at the feed station, and at least one guide roller for the cutter takes the sheeting and forms a loop in the web. A curved lifting device releases the shaft plus its reel from the shaft holder at the winding station and a secondary driven contact roller is applied to the wound reel to move it out. ADVANTAGE - The machine can be driven in either direction for reeling. It has a simple construction.

Title: Variable speed DC traction motor for vehicle - has separate low-current field winding and thyristor controlled excitation for combining advantages of conventional series and shunt wound motors.
Inventor: LEIBE BERTHOLD DIPL ING
IPC: B60L9/04
Filed: 1992-11-12
Abstract: A variable speed DC traction motor for a vehicle is dimensioned to drive the load at approx. 50 percent of nominal load rpm. when its armature (1) is energised at nominal system voltage (11, 9). The separate field winding (3) has a larger number of turns than normal to reduce excitation current and is supplied from an excitation regulator (17) controlled by e.g. a thyristor over the complete range of system voltage. Normal acceleration against load torque up to 1/2 nominal load rpm. is followed by acceleration to nominal load rpm. by progressive weakening of the field with armature direction and regenerative braking controlled by the reversing switch (21, 23). USE/ADVANTAGE - Combines best features of DC series and shunt motors for speed and torque control of traction vehicle using low-cost circuitry. Thyristor controlled excitation independent of load torque materially reduces number of armature current rated contactors compared with equivalent series motor. Field winding dimensioning is similar to shunt motor and short-circuiting of field does not result in high speed 'run-away' as with series motor.

Title: Mechanical holding device in the microphone stand
Inventor: SCHWARZ WERNER
IPC: H04R1/08
Filed: 1993-02-24
Abstract: The holder within the microphone tube is designed in such a manner that this holder can be comfortably detached by the speaker himself/herself in order to be able to perform an up or down movement. In the moving microphone tube, a mechanical blocking device is mounted which presses the spring B downward by pressure on the button E and slides the rod F with the wedge C downward and thus releases the blocking device. Due to this process, the holder of the tube A is released again and the microphone tube with microphone A can be guided in any desired direction. The particular advantage lies in that a second person is no longer required for the adjustment to a particular height or depth with respect to the direction of the mouth of the speaker. This mechanical holding device can be installed in any type of tripod stand in order to achieve a comfortable height or depth with respect to the object. <IMAGE>

Title: Method of machining material by means of a laser
Inventor: ENGELHARDT RALF
IPC: B23K26/122
Filed: 1993-07-15
Abstract: The method serves to machine material by means of a laser in a liquid-filled space. Material is removed inside this liquid-filled space by pulsed laser emission. In order to reduce the pronounced transient pressure increases and cavitation effects which can otherwise be observed during the removal under liquid by means of a laser, the laser machining is effected inside a gas bubble so that the liquid is displaced in this area. The gas is either fed or is produced directly by the laser at the application point.
