Abstract:
Es wird ein Thermostatventilaufsatz (1) angegeben mit einem Thermostatelement (7), das einen Druckraum (8) aufweist, dessen Volumen sich temperaturabhängig verändert, mit einem Betätigungselement (17), das mit einer Dehnzone (14) des Thermostatelements (7) in Wirkverbindung steht, und mit einer Sicherheitsanordnung. Man möchte den Raumbedarf klein halten. Hierzu weist die Sicherheitsanordnung eine Überdruckdehnzone (12) ausserhalb der Dehnzone (15) auf.
Abstract:
The present invention relates to an electronic ignition circuit for oil burners, in particular a high voltage high frequency ignition circuit, said circuit comprising an oscillator and a high frequency high voltage transformer wound on a core (1). The core (1) on which the high frequency transformer is wound forms a substantially closed magnetic path for the magnetic flux generated by the winding of the transformer (T1'), when current flows through the windings (4a-4d).
Abstract:
A method and device are provided for the determination of the concentration of compounds in body tissue. The method utilises optical methods based on the interaction of light with compounds, whereby the concentration of the compound under analysis is determined. The method is especially suited for analysis for the concentration of glucose in blood or tissue of diabetic patients, a device being implanted underneath the skin of the patient and the method being carried out by using the implanted device. The device (1) contains photo detectors (8) at different levels connected by wires (17) to an electronic circuit device (18). A differential analysis is performed on the signals from the detectors (8) to reduce the effect of skin on the analysis.
Abstract:
Es wird eine Zweistoffdüse angegeben mit einer Drallkammer (2), die eine Austrittsdüse (1) aufweist und in die eine Gaskanalanordnung (4, 5) am Umfang und eine Brennstoffkanalanordnung (9, 10) stirnseitig auf der der Austrittsdüse (1) gegenüberliegenden Seite münden, wobei die Drallkammer (2) zumindest im Bereich der Gaskanalanordnung (4, 5) einen kreisförmigen Querschnitt aufweist.Man möchte eine derartige Zweistoffdüse bei Brennstoffzellen verwenden können.Hierzu ist vorgesehen, daß der Durchmesser der Drallkammer (2) um mindestens den Faktor 7 größer ist als der Durchmesser der Austrittsdüse (11).
Abstract:
A process for electrochemical deposition of tantalum on an article in an inert, non-oxidizing atmosphere or under vacuum, in a molten electrolyte containing tantalum ions, comprising the steps of: immersing the article into the molten electrolyte heated to a working temperature, passing an electric current through the elctrolyte to thereby deposit a tantalum coating on the article, wherein the process of tantalum deposition at least in an intitial phase deposits pure α-tantalum.
Abstract:
An implant and a process of modifying an implant surface, which implant is in particular a hip implant, a tooth implant, a bone screw, fixation pin or a fixation nail (pin-fixation), comprising a metallic base body (1), which implant has a surface modified by a tantalum or niobium, for the formation of a surface modification (4) where at least the tissue-friendly metal is alloyed with the surface and constitutes a uniform, diffusion-tight outer zone (2) on the body (1), which outer zone (2) has a higher ductility than the metallic base body (1) in order to obtain a tissue-friendly implant with increased fatigue strength.
Abstract:
The invention concerns an electric motor with a stator (10), in whose bore (13) a rotor is arranged, and with a control arrangement having at least one coil (9) with a core (15) passed by the motor current. The coil shall be arranged in a space saving manner without interfering too much with the magnetic field of the motor. To solve this problem the core (15) of the coil (5, 8, 9) is arranged on the stator (10) whose iron is used for a magnetic circuit.
Abstract:
A process for controlling a refrigeration system, as well as the refrigeration system and a new expansion valve for the refrigeration system. An electronic regulator is used to operate a sensor system having a device for applying heat power to the sensor system in direct dependence on sensed superheat of the refrigerant leaving the evaporator. By locating the sensing system in communication with liquid refrigerant upstream of the evaporator, heat transfer to the liquid refrigerant is utilized for operation of the sensor system rather than heat transfer to the superheat, resulting in a far more stable and efficient refrigeration control.
Abstract:
The invention concerns a radiator valve (1) with a housing (2, 3), a closure element (5) movable in the axial direction (6) towards or away from a valve seat (4) and a tappet (8) movable in the axial direction, which is led to the outside through an opening (9) in the housing (2), by which the opening (9) is sealed through by sealing (10) arranged in the housing (2) and enclosing the tappet (8). On one hand the embodiment of a valve of this kind must be simple, on the other hand it must enable inexpensive and simple repairing when leakages occur. For this purpose sealing room (12) surrounding the tappet (8) is arranged outside the housing (2), in which an additional sealing (16) can be placed. The housing (2) has a projection (14) providing a fixing for a sealing holder (17).
