Title: Element for play-free centring
Inventor: POESCHL GUENTER
IPC: F16D1/08
Filed: 1993-03-05
Abstract: An element for play-free centring of the rotational body (20) in a bore (28) is designed as a coil (10) which is to be inserted between the rotational body (20) and the bore (28), of which the turns are spaced apart axially from one another and which has a cross-sectional profile which, in the event of radial loading, in particular in the event of an increase in temperature, is subjected to torsion.

Title: Process for purifying or treating contaminated gas
Inventor: WANDKE ERNST DIPL ING DR ING
IPC: B01D5/00
Filed: 1993-07-21
Abstract: The invention relates to a process for purifying or treating contaminated gas, in which contaminants such as in particular CO2, H2O or NH3 are condensed or frozen out of the gas by reducing the temperature of the flowing gas and in which portions of the contaminants separated out remain in and are entrained by the gas stream in the form of ice crystal particles or liquid particles. The removal of these entrained particles is achieved according to the invention by the gas stream containing the particles being run through an electric field of high potential difference, preferably in a region of retarded gas flow in the course of purification or in continuous flow, which causes the entrained particles to be discharged from the gas stream in accordance with the action of the electrical field force on them.

Title: Glass plate-bevelling (chamfering) machine
Inventor: PARK KYUNG
IPC: B24B9/10
Filed: 1994-01-07
Abstract: There is described a glass plate-bevelling machine which is improved in such a way that it is suitable for the partial bevelling of a glass plate. When a partial bevelling is carried out with a conventionally designed glass plate-bevelling machine, at that moment when one of the two rollers for following the shape of the glass plate leaves the end point of the glass plate, one of the rollers is turned in the direction towards the straight edge, so that the bevelling wheel is also automatically turned. Consequently, the bevelling direction is departed from, with the result that a correct bevelling is impossible or an incorrect bevelling is produced. This disadvantage is avoided in that the bevelling wheel is not turned even when one of the two rollers deviates from the corner. A horizontal bearing cushion supports a device for following the shape of the glass plate and also, in addition, an adjusting-feeler control plate equipped with an adjusting-feeler guide slot. An end portion of the adjusting feeler is pivotably supported by the adjusting-feeler guide slot. Located under the bearing cushion is a pneumatic cylinder for fixing an adjusting feeler. The pneumatic cylinder 28 is actuated via numerical controls, while the adjusting feeler is controlled by the pneumatic cylinder, with the result that the device for following the shape of the glass plate is fixed or released exactly at the required locations. Thus, a partial-bevelling operation is automatically and continuously carried out by the bevelling machine.

Title: Laser cutting of thick walled sheet
Inventor: MAKASEV NIKOLAJ
IPC: B23K26/364
Filed: 1994-03-08
Abstract: Laser cutting method in which the laser gas from the nozzle creates a high pressure zone around the cut. This zone starts at the front end of the cut and extends back along the cut for a distance equal to 40-60% of the workpiece thickness. The width of the laser beam in the cutting direction is 5-10 % the thickness of the workpiece. The nozzle of the laser gun has an outlet whose length along the cutting line is 40-60 % the thickness of the workpiece and whose width transverse to the cutting line is 100-150% that of the laser beam width. The downward end of the nozzle approx. corresponds to that of the forward end of the laser beam. In an alternative embodiment, a pair of symmetrically located nozzles is used at an angle of 150-300 to the cutting plane. Both nozzles can be angularly altered by moving on parallel rails. The nozzles can also be split into 2 or 3 with the smaller nozzle used to pass chemically active gas and the larger nozzle used to pass inert gas. The second larger nozzle enables the gun to b moved in the opposite direction without having to change the order of the nozzles.
