Title: Verfahren und programmierbare beleuchtungsvorrichtung zur hochauflösenden, massiv parallelen, räumlichen synthese und analyse von microarrays
Inventor: ROGALLA MARCEL
IPC: B01J19/00
Filed: 2003-07-03
Abstract: Die Erfindung betrifft ein Verfahren und eine programmierbare Beleuchtungsvorrichtung zur hochauflösenden, massiv parallelen, räumlichen Synthese oder Analyse von Microarrays. Die Erfindung ermöglicht es, gemäss einer Spezifikation zweidimensionale strukturierte Laserlicht-Punktmuster in einem Raum-, Zeit- und Wellenlängen-Multiplexverfahren zu erzeugen. Diese Punktmuster sind auf Rastern definiert, können leicht 10000 bis 100000 Lichtpunkte pro Quadratzentimeter haben, und dafür genutzt werden, Substanzen an den beleuchteten Positionen der Lichtmuster auf festen Oberflächen ablagern zu lassen. Nach dem gleichen Schema kann die Beleuchtungseinrichtung auch genutzt werden, um Microarrays mit spezifizierten zeitlichen Abfolgen zweidimensionaler Laserlicht-Punktmuster mit verschiedenen Wellenlängen zu beleuchten und dadurch Fluoreszenzeffekte für Analyseverfahren zu erzeugen. Die Erfindung beinhaltet die Realisation von digitalen Transmissionsfunktionen mittels elektrisch schaltbarer, mikrostrukturierter Optiken, welche durch Beleuchtung mit einer Laserlichtquelle und unter Ausnutzung des Beugungseffektes in einer definierten Bildebene spezifizierte Laserlicht-Punktmuster im Zeitmultiplex-Verfahren erzeugen.

Title: Synthetic diamonds from aromatic hydrocracked- - bons
IPC: B01J3/06
Filed: 1969-08-29
Abstract: C3 crystals are produced using C cpd. with more than two atoms in mol. as starting material, e.g. naphthalene, anthracene or benzene. Proportionate wt. of reagent (e.g. SiO2, H2O2 and/or O2) is added which combines with substances other than C, so that C is liberated. These materials are compressed to density of diamond (e.g. 3.5. g./cc) and only the heated to is approx. 2000 degrees C, ensuring that chemical reacted cannot occur until density reaches desired value. Initial reaction temp., reaction rate and magnitude of heat generated can be regulated, within limits, by suitable choice or mixing of reagents. These larger mols., having part of electrons already delocalised, are more easily converted to diamond (C3) than is graphite (C2). Colouring additives may be incorporated.

Title: Plate fin heat exchanger - with continuous sealing strip
Inventor: GUIDO JUERGEN DIPL ING
IPC: F28F3/10
Filed: 1972-08-08

Title: Drainage element where wall touches earth - has slits in front plate leading to drainage channels in cavity with plastic foil back
Inventor: DENNERT HEINZ
IPC: E04B1/70
Filed: 1973-08-31
Abstract: Drainage element for wall to drain the ground in front of the wall at its point of contact consists of a hollow sandwich plate. The back of the plate made of plastic foil, facing the drainage wall does not allow water through and the front of the plate facing the earth does through vertical slits.

Title: Open ended cold formed metal container - is directly supported internally and rotated during forming to give uniform wall thickness
Inventor: KINDELVICH FREDERICK THEODOR
IPC: B21D22/14
Filed: 1973-09-13
Abstract: The metal container is initially cold worked and it is processed into its final shape without deterioration of the mechanical properties or of the surface finish. The metal is caused to flow by a force which slightly exceeds the yield point. The process is carried out by using an internal mandrel and an external forming roll. The container material is contacted selectively by a roll during its movement and the cold flow of the material is controlled. The combination of the mandrel and roll act aproximately as deep drawing tools on the container. Complicated shapes can be produced at relatively low costs and at high speeds. The closed end of the container is sandwiched between the rotating surfaces for rotating the container for processing.

Title: Connecting of corners of window and door frames - pins are inserted in bores in corner angle and profile bare and fixed by press tool
Inventor: FRITSCH JOHANN
IPC: E06B3/98
Filed: 1973-11-24
Abstract: Connecting of the corners of window- and door frames, which consists of mitred metal hollow profiles where in the open ends of the hollow profile a connecting corner angle is inserted, which like the profile bar has transverse bores into which pins are pressed with a conical, or wedge-shaped face. Specifically, the pins are first inserted only partly into the bores and then with the aid of a press tool which can move in the bevel direction, simultaneously and synchronously two symmetrical pressure movements are derived which run exclusively in the direction of the bores axes. The pressure thus exerted on the ends of the profile bars is accepted by stops which are parallel to the axis of the bars to be connected and above the bore region.

Title: Insulator for a plastics-film processing roller - used for surface-treating film to render it suitable for accepting print
IPC: B29C63/00
Filed: 1974-03-18
Abstract: Insulation for a film pre-treating roller comprises an insulating tape wound onto the roller in abutting (i.e. non-overlapping) windings. The insulation stabilises the electrical discharge with which the plastics film is being treated so as to render it printable-upon. The insulation is more easily applied to the roller than prior-art silicone-type tubular coverings. Risk of voids is minimised.
