Title: Torque converter pump impeller - has pretensioned inner shell for ease of impeller assembly and therefore reduced precision manufacture
Inventor: MAGNUSSEN GERHARD DIPL ING
IPC: F16H41/28
Filed: 1992-04-01
Abstract: A pump impeller comprises an outer shell (1) and an inner shell (2) with blades (3) arranged radially in between. Both axial sides of the blade have a contour matching the respective outer and inner side of the inner and outer shells. The inner shell is pretensioned prior to assembly such that both ring contours lie in parallel, axially aligned planes. Upon alignment of the inner shell upon the blades, lying in the outer shell, the radially inner region is in contact with the blades. The radially outer region of the inner shell however has a small separation from the blades. This separation is smaller than its effective elastic deformability, and allows the blades to sit freely on the inner wall of the outer shell, without requiring precise form manufacture. ADVANTAGE - Easier manufacture.

Title: Point-like alignment of film, video and photographic cameras and lamps and flashlamps in underwater use by means of laser technology
Inventor: WIENDL HORST DIPL ING
IPC: G03B15/05
Filed: 1993-09-02
Abstract: In comparison with air, water has a density which is higher by a factor of 1.33. Objects are larger by a factor of 1.33 (refractive index of water). As a result of the density, objects are seen to be closer by 1/4. This leads to misalignments of recording equipment (film, photographic, video) and illuminating attachments. Under water, flashlamps and also luminaires are nowadays operated on two-dimensionally and three-dimensionally adjustable articulated brackets. The alignment of the luminous cone or the flash angle relative to the centre of the optical axis of film, video and photographic cameras is difficult and this leads not only to incorrect exposures but also to pictures with an inadequate illumination quality, e.g. underexposed black picture corners as a result of the incorrect alignment of light. A further disadvantage which emerges is the fact that the flexible articulated brackets can be readjusted without being noticed and that the illumination angles no longer coincide with the previously set image angle. The discrepancy between image axis and light axis becomes ever greater as the object is approached, and thus also the exposure error. For precise alignment of the reflector angle relative to the optical axis or to the centre of the image, a normal light source, e.g. halogen burner, can be used only to a limited extent. In the case of insolation, the luminous power (luminosity, brightness) is not sufficient to influence the image field in terms of brightness, never mind determine the centre of the light point, and is for these reasons ruled out as adjustment aid.

Title: Process for producing methanol
Inventor: ELIASSON BALDUR DR
IPC: B01J23/70
Filed: 1993-09-27
Abstract: To produce methanol from carbon dioxide and hydrogen, the starting substances carbon dioxide and hydrogen are fed to a thermal reactor and are converted into methanol therein at elevated pressure and in the presence of a catalyst. Particularly high conversion rates are achieved by the mixture of carbon dioxide and hydrogen being introduced into the thermal reactor from the top and then passing through the catalyst in the lower section of the reactor. The catalyst used is one based on copper. The residence time in the catalyst depends upon the temperature in the reaction department in such a way that the value of the quotient of residence time sv and temperature T is between 10 and 50, the residence time sv being defined as the gas volume/hour divided by the total amount of gas and the temperature T being measured in degrees celsius. <IMAGE>
