Title: Tool to mfr. stainless steel kitchen sinks - has bending rail with step, adjustable in height by wedges
Inventor: KOERNER RALF
IPC: B21D22/26
Filed: 1991-08-22
Abstract: The tool consists of two parts (1, 2), moving towards or away from, each other. One part has a bending die (13), the other has a bending rail (16). The bending rail has a step, which impacts on the bending edge of the metal plate (4). Adjustment is by a number of support wedges, which carry the bending rail, and are displaceable at right angles to the adjusting direction. The wedges are adjustable by screws. The width of the gap is adjustable, by displacing the section of the bending rail, forming the gap, parallel to the metal plane. USE/ADVANTAGE - Tool for mfr. of stainless steel kitchen sinks ensures that fold is of same size all round, so that formation of corrugations is avoided.

Title: Method for hydraulic expansion of closed hollow profiles - processes blank, which is pre-profiled before hydraulic expansion
Inventor: KAEMPEN KLAUS IN DEN DR ING
IPC: B21D26/02
Filed: 1992-04-28
Abstract: The method is esp. for use with profiles, which have sections of different dia. After sealing the ends of the open blank, internal pressure is applied hydraulically, and the material is pressed against a mould, which surrounds it. A tubular blank is pre-profiled, so that relative to the required overall expansion, the number of circumferential sections with high stretching strain is small relative to the number of sections, which are mainly bent in the wall. After the preformed part is placed in a mould, it is expanded hydraulically. The second mentioned sections engage first on the inside of the mould, and after the pressure has been increased, the small and angled sections are formed. USE/ADVANTAGE - Easy mfr. of closed profiles with complicated or narrow sections.

Title: Paper pulp suspension air removal - uses underpressure from cleaner reject for air removal
Inventor: GMEINER ANTON DIPL ING
IPC: D21D5/26
Filed: 1992-12-11
Abstract: To extract air from a paper pulp suspension, the overflow reject of the hydrocyclone cleaner (3) passes into the container (15) giving separation of two phases. The gas and air-filled section extends into the part of the cleaner filled with gas and air to extract air and gas from the separated phase zone. The air-filled section of the degassing zone is connected to the container (15) holding the reject, with throttling to give a pressure difference between the degassing zone and at least most of the container (15) for the cleaner (3) reject. USE/ADVANTAGE - The method is for the extraction of air from the pulp for the prodn. of newsprint and other papers produced on a high-speed papermaking machine, where the pulp is of wood, or used paper after ink removal or cellulose after separation of particles which would give faults. The reject overflow action from the cleaner gives a sufficient underpressure for the air removal from the pulp, in a simple assembly occupying little space.

Patent DE-4314486-A1 (DE)
Inventor: THIEL JUERGEN DIPL PHYS
IPC: G01B9/02
Filed: 1993-05-03
Abstract: 2.1 Known measurement methods and measuring arrangements have the disadvantage that the measurement of the phase change in the interference signals which is necessary for determining the measured distance is performed with a resolution of at most approximately 1/10 of the total wavelength. However, this resolution comes nowhere near the resolution which can be achieved using other methods. Moreover, because of the ignorance of the wavelength no relative measurements can be carried out following an absolute measurement. 2.2 This disadvantage is overcome in the measurement method according to the invention owing to the fact that at the ends of each measurement cycle the air wavelength of the laser beam is controlled to a specific wavelength value by means of an additionally provided control interferometer having a control section which is shorter than the measurement section and thereafter the air wavelength is continuously tuned within a specific wavelength interval and controlled to the final value by means of the control interferometer. The phase change in the interference signal is continuously detected during the wavelength modulation. A simple mathematical relationship can be used to determine the measurement section from the measured wavelengths and the phase shift. Relating the measurement uncertainty of this method to that of the conventional interferometers can be achieved by using a further laser having at least one further discrete wavelength by generating a beat wavelength, which must be greater than the measurement uncertainty owing to the continuous tuning of the wavelength. It is possible, furthermore, to use this method to carry out relative measurements following an absolute measurement. 2.3. The measurement method and the laser interferometer arrangement are suitable, in particular, for absolute distance measurements. <IMAGE>

Title: Braking system, in particular for muscle-powered two-wheeled vehicles
Inventor: JAHN GISELA
IPC: B62L3/08
Filed: 1993-08-16
Abstract: The invention relates to a braking system in which the braking forces of the rear-wheel brake are used to operate the front-wheel brake. This takes place via brake-shoe holders of the rear-wheel rim brake, which brake-shoe holders are movable in the circumferential direction of the road wheel. By means of a brake-operating mechanism the deflection of the brake-shoe holders which has taken place as a function of the braking forces of the rear wheel is used to operate the front-wheel brake. The front-wheel brake is put into operation independently of the braking system by means of a brake lever arranged in the customary manner. By virtue of a stop for limiting the deflection of the brake-shoe holders the braking system is maintained with two brakes which can be operated independently of each other in the event of a defect in the brake-operating mechanism between the rear-wheel rim brake and front-wheel rim brake. <IMAGE>
