Title: Collet chuck
Inventor: HEIMANN ULRICH
IPC: B25B5/06
Filed: 1997-01-26
Abstract: The collet chuck has two arms to grip a workpiece between their free ends. One arm can move along a carrier rail which has a lever mechanism able to lock the movable arm in a tilted position. The lever mechanism (20), starting from the unlocking position, in a first clamping step, fixes the arm (14) in the longitudinal direction of the carrier rail (10), without appreciably tilting the arm. In its second step, the lever mechanism tilts the arm relative to the rail, bringing them closer together, without releasing the previous position fixing.

Patent DE-19729258-A1 (DE)
Title: Cleaning of solvent, e.g. per:chlor:ethylene
Inventor: BRINKER EWALD
IPC: D06F43/08
Filed: 1997-07-09
Abstract: In the cleaning of a solvent, e.g. perchlorethylene used in a textile cleaning process, before it is necessary to remove the distillation residues from the distillation cooling system solvent outlet, a mixture of air and solvent is sucked from the distillation cooling system via a liquid separator. With the heating system in operation, the solvent is blown into the distillation residue reservoir. The distillation residue is aerated, the remaining solvent is liberated, evaporated and then condensed in the distillation cooling section, following which the mixture of air and solvent is again exhausted, passed through the distillation cooler and liquid separator, and the air is then expelled into the distillation reservoir. The air circulation process is repeated until the solvent recovered from the distillation reservoir falls below a pre-determined level.

Opposite peripheral parts of the walls form a gap between the hole and the chain channel which allows the penetration of the gear teeth into the chain channel.  Around the central hole runs a peripheral edge which lies on an annular shoulder of the corresponding gear wheel and supports its movement. Each of the housings has a lip in the area of the inner diameter of the peripheral edge which stretches inwards from here in order to give the corresponding gear wheel some axial pressure.

Patent DE-19738914-A1 (DE)
Inventor: ENGLERT ULRICH DIPL ING
IPC: H04N5/12
Filed: 1997-09-05
Abstract: The inventive digital PLL circuit (2) consists of a phase detector (4) which receives an external synchronisation signal (to) and a first feedback signal and produces a phase difference signal. The value of said phase difference signal is a measure of the phase difference between a synchronisation signal (to) and the first feedback signal. The circuit also comprises a DTO (20) which is connected downstream from the phase detector (4), said DTO (20) producing an n-bit wide digital output signal according to the phase difference signal, a feedback device for conveying the output signal of the DTO (20) to the phase detector (4) as a first feedback signal, and a decoding device (14) which is connected to the output of the DTO (20) and which has an output (16) for a correction signal. Said correction signal represents a measure of the phase relation between two scanning values and is derived from at least a subset m of the bits of the second feedback signal. The digital PLL circuit is particularly useful for regenerating horizontal synchronisation in televisions, using the pixel timing.

Patent DE-19823958-A1 (DE)
Inventor: SCHMITT PETER
IPC: H04N5/325
Filed: 1998-05-28
Abstract: The invention relates to a method for imaging in digital dental radioscopy using a sensor array, the individual image elements (1 to 25, 51, 52, 53) of which are smaller than the desired local resolution so that a plurality of image elements (1 to 25) forms an effective image element (100, 200). First reference signals are initially detected, which are generated by the image elements of the sensor array when the latter is not exposed to X-radiation. In addition, second reference signals are detected, which are generated by the image elements of the sensor array when the latter is not exposed to X-radiation. Subsequently, defective image elements (7, 19) are determined on the basis of the detected first and second reference signals, whereupon an image of an object is generated using exclusively the image element that has been determined as being non-defective. It can also be determined during generation of the image of an object whether the object signal detected for the corresponding image element has been directly hit by an X-ray quantum. Image elements (51) that have been directly hit by an X-ray quantum are not used for generating the image of an object.
