Title: Compact transverse flow gas laser - passes gas in same direction through discharge channels, and inverts relative position of radiation fields in direction parallel to flow direction
Inventor: SCHOCK WOLFRAM DR
IPC: H01S3/07
Filed: 1992-09-01
Abstract: The laser has two discharge channels (12) through which a laser gas flows. The resonance radiation field of a resonator in the transverse direction is made up of several partial fields. The differences in optical wavelengths of the partial fields are reduced due to density gradients. A branch of each channel (12) passes through the resonance field. The resonator surrounds a mirror element (60,120,150). This couples the branches of the field together such that they define an angle of 90 deg. or less. Laser gas flows through both discharge channels (12) in identical flow directions (30). The mirror element (60,120,150) inverts the relative position of the partial field (84,86) with respect to at least one inversion direction (88,134,152) parallel to the transverse direction (80) of the resonance field (54). ADVANTAGE - Simple and compact structure.

Filed: 1993-04-06
Abstract: 2.1 In paint spraying installations, the workpieces to be sprayed are transported through the spray booth (10) by means of a belt conveyor (12). As a result, the surface of the conveyor belt (13) is also provided with a paint or enamel application. However, it is necessary for the conveyor belt to be carefully cleaned after the removal of the workpieces. A paint spraying installation is to be further developed in such a way that the quantity of solvent required for the cleaning is substantially reduced. In addition, the doctor device for cleaning the surface of the conveyor belt (13) is to be readily accessible for maintenance work and is also to permit a quick paint change. 2.2 In the paint spraying installation according to the invention, the top strand of the conveyor belt (13) is deflected in the direction of the bottom strand by a deflection roller (16) mounted in the area of the discharge side of the spray booth (10). The top strand of the conveyor belt runs at an angle in this area. The doctor device is allocated to this sloping area. The doctor device essentially consists of at least one rotary doctor blade which can be driven in a rotational manner. The rotation axis of the rotary doctor blade (22) is perpendicular to the surface of the conveyor belt (13) to be cleaned. 2.3 The paint spraying installation according to the invention is especially suitable for spraying flat components such as, for example, parts of furniture. <IMAGE>

Title: Sewage treatment plant operating by the SBR principle
Inventor: KOTZBAUER ULRICH
IPC: C02F3/12
Filed: 1993-09-27
Abstract: In known sewage treatment plants, an expansion of the connected capacity or an alteration of the process strategy is only possible with limitations. The solution presented is to enable the expansion and alteration of the process strategy in a simple and cost-effective manner. In order to enable the expansion of the connected capacity and the process strategy, existing sewage treatment plants or tanks utilised in other ways are modified in such a way that hydraulic uncoupling of the individual components is enabled. This is enabled in particular by the addition and/or removal of individual components or units. In addition to conversion, this is also possible in a simple and cost-effective manner in the event of complete new construction. The area of application covers the purification of municipal and industrial waste waters.
