Title: Optical position measuring unit and optical coordinate input unit
Inventor: OGAWA YASUJI
IPC: G06F3/033
Filed: 1994-03-23
Abstract: Optical position measuring unit, comprising: a light-receiving device, including a pixel field, for forming a light-receiving region and for outputting signals with respect to the light detected by each pixel in the pixel field; a patterned material which is arranged upstream of the light-receiving region of the light-receiving device and has a pattern with a characteristic such that a part of the pattern is projected onto the light-receiving region by an incident light beam in such a way that an image of this part of the pattern uniquely determines the direction of incidence of the light beam; and a signal processing device for extracting information with respect to the direction of incidence of the light beam on the basis of the signals output by respective pixels in the pixel field. The pattern preferably has an M-sequence characteristic. Furthermore, an optical coordinate input unit is implemented with the use of a coordinated detector which is formed by the use of at least two optical position detecting units of the type described above, and of a position indicator including a light-emitting region.

Patent DE-4437739-A1 (DE)
Inventor: RAUCH GERHARD DIPL ING
IPC: G01N33/00
Filed: 1994-10-21
Abstract: In order that the pollutant concentration in exhaust gases may be measured, especially when said gases are collected before analysis, they are diluted with air so that the water vapour in them does not condense and falsify the measurements. According to the present invention, a constant-flow sample of the exhaust gas to be analysed is taken and mixed with a constant stream of clean air. A measuring gas stream proportional to that of the exhaust gas is taken from the constant flow of mixed gas and taken to a collection tank or analysing instrument. The invention is applied in the measurement of the pollutant emission of internal combustion engines.
Patent DE-4438777-A1 (DE)
Inventor: MEYER HEINRICH DR
IPC: H05K3/46
Filed: 1994-10-18
Abstract: To manufacture electrical circuit bases with extremely fine conducting paths, laminates without metal foil coverings are used as the initial materials; to produce the holes, a temporary metal layer is applied to the laminate surfaces, that metal layer is structured and etched and removed from the laminate surfaces once the holes have been etched in the laminate. A foundation metal layer is then deposited on the laminate surfaces, including the hole walls, to create the conducting paths; this is done by the glow discharge decomposition of volatile metal compounds. Further metal layers are applied to those layers without current and/or electrolytically. The metal layers are structured using photomask techniques.

Title: Automatic pretzel shaping
Inventor: SCHNEEBERGER MICHAEL
IPC: A21B5/06
Filed: 1994-12-30
Abstract: Automatic shaping of dough strips into pretzels comprises transferring the dough loop to a conveyor support surface (17) after or during the twisting action of the looping and lifting assembly (3). The assembly (3) is at the same or higher speed than the pick-up conveyor. The centre of the dough is moved towards the conveyor (17) to support the transfer operation with a shaped and/or force grip on the dough. The overlapping of the dough loop is effected by the interplay between at least two conveyor surfaces, where at least one acts as the transfer unit at a given point in time. Also claimed is an appts. with a carrier (18) on a recirculating support (19) to draw the centre of the dough loop onto the conveyor surface (17).
Patent WO-8707011-A1 (WO)
Inventor: HEIZMANN FRIEDER
IPC: B23B49/00
Filed: 1987-04-11
Abstract: Une source de rayonnement (10) projette un motif optique sur la surface (17) de la pièce à usiner (18) et le rayonnement (26) réfléchi par la surface (17, 22) est reproduit sur un récepteur de rayonnement (30). Différentes distances (16, 19) donnent différentes positions des images (27, 28) de la surface reproduite (17, 22) dans un champ d'image (25). Les distances (16, 19) sont déduites des positions des images (27, 28) par un dispositif de traitement de signaux (32). Ce procédé convient particulièrement pour mesurer la profondeur de trous percés. Une profondeur de consigne est prédéterminée à l'aide d'un dispositif d'entrée (33). La profondeur du trou percé est continuellement mesurée pendant l'opération et affichée sur un dispositif optique de sortie. Quand la profondeur de consigne est atteinte, un signal acoustique est délivré et le moteur d'entraînement (37) est débranché.
Patent WO-8808670-A1 (WO)
Title: Filling head for a device for the production of pastries
Inventor: MUELLER FRANZJOSEF
IPC: A22C7/00
Filed: 1988-05-13
Abstract: Pastries produced by means of a filling head are composed of slices containing regions made of different types of dough and thereby represent, for example, a face. These regions are obtained by the use of filling tubes (38-46) of different shapes and cross-sections. The dough would pass more slowly through filling tubes of narrow cross-section, which would result in regions of small thickness. To prevent this, a perforated plate (58) is arranged in the filling tubes (38-46) in such a way as to impede the passage of the dough through all the filling tubes and maintain it at a constant low rate.

Title: Hydrophober, stoffdurchlässiger verbundwerkstoff, verfahren zu dessen herstellung und dessen verwendung
Inventor: HYING CHRISTIAN

Filed: 1999-03-20
Abstract: Die Erfindung betrifft einen hydrophoben, stoffdurchlässigen Verbundwerkstoff, ein Verfahren zur Herstellung eines hydrophoben, stoffdurchlässigen Verbundwerkstoffs und die Nutzung dieses Verbundwerkstoffs in verschiedenen Prozessen. Hydrophobe, stoffdurchlässige Materialien sind seit langem bekannt. Vor allem Materialien aus Kunststoff, wie z.B. Gore-Tex®, aber auch aus anderen organischen Polymeren werden eingesetzt, wenn ein Stoffdurchgang nur in Form von Gas oder Dampf, nicht aber in Form von Flüssigkeit erfolgen soll. Diese Materialien haben den Nachteil, daß sie nur in einem begrenzten Temperaturbereich einsetzbar sind. Der erfindungsgemäße Verbundwerkstoff zeichnet sich durch eine höhere Temperaturbeständigkeit aus, da er überwiegend aus anorganischen Materialien besteht. Da der erfindungsgemäße Verbundwerkstoff über die Sol-Gel-Technik erhältlich ist, ist die Herstellung des Verbundwerkstoffes relativ einfach. Der erfindungsgemäße Verbundwerkstoff kann als Membran bei der Oxidation von Aromaten, z.B. bei der Diorektoxidation Benzol zu Phenol, eingesetzt werden.
