Title: Double four drinker paper-making press section - has forming roller for lower four drinker at entry with water extn. unit and further forming roller at upper four drinker
Inventor: MUELLER KARL
IPC: D21F9/00
Filed: 1992-03-18
Abstract: Machine has a forming roller (4) at the press section, over the lower fourdrinier (3) where the two fourdrininers (2, 3) come together, so taht they both pass partially round it. A water removal unit, esp. a water suction chamber (6), is near the forming roller (4) or close behind it, at the upper fourdrinier, followed by a forming shoe (7) with bars (12) across the direction of material travel. Further forming rollers (8) are at the upper fourdrinier. The water extn.-chamber (6) pref. has a suction lip (5) pressed tighly against the upper fourdrinier. The forming shoe (7) at the lower fourdrinier (3) is pref. part of the suction chabmer (11) for the lower fourdrinier, with bars (12) giving a convex contour surface towards the lower fourdrinier (3). The forming shoe (7) can also be part of the suction chamber (6) for the upper fourdrinier (2), with bars (12) presenting a convex contour surface to the fourdrinier. The forming roller (4), near the stock inlet, has water retaining recesses at its outer mantle surface, without connections to the roller interior, as do the forming rollers (8) at the upper fourdrinier. The recesses in the upper forming rollers can be connected to the roller interior, with a non-rotating suction chamber to extract wafer from within the roller. The upper forming roller can also have a polished mantle, impermeable to water. A water removal unit (9), with underpressure, is between the forming shoe (7) at the lower fourdrinier (3) and the further forming rollers (8) at the upper fourdriner (2), to remove water through the upper fourdinier (2). The peak of the forming roller (4) at the lower fourdinier is higher than the level of the bars (12) at the suction chamber. A water container (10), after the upper forming roller (8), traps water spun from the roller, to be led away from the press section. USE/ADVANTAGE - The press section of the papermaking machine, as structured, gives an effective water extn. from the pulp with relatively short-length suction chambers at the lower fourdrinier and with high-speed fourdriniers, without web damage. The assembly occupies little space with reduced suction air consumption.

Title: Material identification using spectroscopy and two laser light sources, e.g. for differentiation of human tissue - illuminating material with light at two wavelengths and determining intensity of luminescence or scattered light emitted from material in wavelength range below upper illuminating frequency
Inventor: ENGELHARDT RALF
IPC: A61B18/24
Filed: 1992-05-15
Abstract: The method involves illuminating the material to be identified with a frequency lambda 1, detecting the intensity of light emitted from the material between wavelengths lambda 2 and lambda 3, and comparing with values for known materials. The material (11) to be identified is additionally illuminated with the light of a fourth wavelength (lambda 4). This lies above the wavelength range of the second and third wavelengths (lambda 2 and lambda 3). Two lasers (7,8) are used as light sources and respectively produce light of first and fourth wavelengths (lambda 1 and 4). The light is fed into an optical waveguide (10) across a beam splitter (9) and led to the material being identified. The light emitted is fed across a second beam splitter (12) to an evaluator (13). USE/ADVANTAGE - For removing layers of dirt, lacquer, etc. without harming substrate material; cutting using stencil; medical applications, e.g. stone and tumour destruction, plaque removal from teeth. Clearer differentiation between materials of similar types.

To form the recess, a part of the bottom ram is, before or after the introduction of the material forming the sole body, brought into the mould into contact at least in areas with the cover sole. As a result, an at least partially circumferential interspace is formed, the shape of which corresponds essentially to the shape of the lateral delimiting walls of the sole body, which delimit the recess. The container with the granular material is subsequently inserted into the recess which is sealed with the outsole. <IMAGE>

Title: Device for measuring surface structures of patterns
Inventor: AHLERS ROLF-JUERGEN DR
IPC: B23K26/08
Filed: 1993-06-30
Abstract: It is known to structure the top side of metal moulds and graphite electrodes for the metal moulds by means of a laser abraiding machine. It is also known for picture copies (original pictures, master photographic images) and image patterns to be read into computers by means of scanners and transferred onto tools. In order to be able to use the device to measure surface structures of patterns in such a way that at least approximately identical surface structures can be fashioned on parts to be produced, the device has a camera which records the surface structure of the pattern in two dimensions and is connected to a processing unit. It processes the signals delivered by the camera by means of signals of a sensing system which detects the depth of the surface structure, and makes the conditioned data available at a data output. A tool of a cutting machine can be controlled via these data. Using the device, the tool of a cutting machine can be controlled with the aid of the conditioned data, with the result that it is possible to cut parts made from metal, ceramic, plastic or other materials.
