Abstract:
A method is described for separating off trace components from a fraction (1) containing at least nitrogen and helium, wherein this fraction is partially condensed (E) before enrichment of the helium. The partially condensed fraction (2) is fed at least in part to at least one separation column (T) and separated therein into a helium-rich gas fraction (6) and a nitrogen-rich liquid fraction which also contains the unwanted trace components (5).
Abstract:
The present invention relates to a sleeping device, such as a mattress, quilt or pillow, wherein the sleeping device is adapted to be used by a person during rest and comprises a core element, wherein said core element is covered by a first layer of a material having temperature regulating properties by absorbing and releasing heat and a second layer of down. By using a material with temperature regulating properties together with a layer of down filling, very good properties of minimizing temperature variations are obtained.
Abstract:
An apparatus for injecting compressed air into a liquid comprises a tubular basic body such as a pipe that is surrounded by a perforated membrane through which air is distributed into wastewater and is connected to the nipple of a compressed air supply through a hollow and cylindrical member that transfers compressed air to the space between the membrane and the tubular basic body and also has a passageway for wastewater so that wastewater can flow through the tubular basic body, thereby avoiding stagnant areas of untreated wastewater.
Abstract:
A method for the manufacturing of a metal core pc board which provides for manufacturing of two or three dimensional metal core pc boards of any form. The manufacturing of such pc boards can occur by injection molding, injection/compression methods or by a pressing method. High-heat resistant thermoplastics, as well as thermoset plastics are preferably used as pc board materials. A metal with good thermal conductibility is used for the core. The material is selected such that the thermal expansion coefficients of the metal core and the pc board material are optimally equal. The manufacturing contains the following steps: lamination of the metal plate with a plastic foil on one or both sides; placing of such prepared metal core in an injection molding tool; and thermoforming the plastic on the laminated core over the plastic foil.
Abstract:
A physiological monitoring device receives a plurality of physiological measurements, including the user's diastolic and systolic blood pressure, pulse rate and body temperature. The physiological measurements are stored in a memory which is controlled by a microprocessor. The microprocessor organizes the measurements and causes the measurements to be displayed for analysis on a screen in either digital or graph form, printed in either digital or graph form and/or transmitted over a phone line or other communication link for reproduction in either digital or graph from at a distant receiver located, for example, in a doctors office or hospital.
Abstract:
A tantalum capacitor comprising a cylindrical body and an axial tantalum anode wire. This wire is first folded and then soldered to an anode connection wire roughly parallel to a cathode connection wire which is itself soldered to the body of this capacitor. The connection wires include preferably a double right-angled section so that the distance between the outward portions of this wire correspond to predetermined standards.
Abstract:
The invention relates to a photographic camera of high quality and extremely small dimensions. To this end the camera objective and the film track are provided on the front and rear faces, respectively, of a generally block-shaped central housing body. An upper housing portion extends on both sides laterally beyond the central housing body and carries, on its projecting parts, the film drive motor and a battery. A lower housing portion defines chamber members on both sides of the central housing body. These chamber members are open at the top and are interconnected by a rear wall and a bottom plate to define a space therebetween which accommodates the central housing body. The take-up and supply spools are located in the chamber members and, in turn, accommodate the film drive motor and battery, respectively, which project downwards from the upper housing portion.
Abstract:
A self reversing drive mechanism is disclosed for providing a reversible speed reducing drive between a drive shaft and the rotary tuner mechanism of a television receiver. The drive mechanism comprises an idler wheel freely pivotally mounted about the drive shaft and in engagement with it. The idler wheel has a circumference which is greater than the distance between the drive shaft and the driven member of the rotatable tuner. As a result, the idler wheel mechanism rotates about the drive shaft in either direction until itself engages with the driven member of the rotary tuner. This is done without any additional external forces to accomplish tight engagement of the idler wheel between the drive shaft and the driven member.
Abstract:
A turret indicator for a television receiver includes a stationary gear attached to a mounting base with a shaft passing through it. A rotatable carrier turret is mounted on the shaft and it carries five rotatable planetary indicator turrets which are programmed with channel numbers, five on each indicator turret to give a total of 25 indicating positions. When the rotatable carrier turret is rotated, the numerals on the indicator turrets appear sequentially at a viewing window in the television receiver cabinet.
Abstract:
In a mounting device for the heel of a ski boot, a sole depressor is lockable in a heel-engaging pivoted position irrespective of the sole thickness or any snow packed beneath the sole. A locking arm carried by the sole depressor or a frame member passes through a hole in a clamping plate pivoted to the frame member or depressor, respectively. A spring acts on the clamping plate so that the locking arm is canted in the hole and binds on the edges of the hole, thereby locking the sole depressor against movement to a heel-releasing position. A handle can deliberately unlock the sole depressor by straightening the clamping plate against the action of the spring so that the locking arm is no longer canted and no longer binds on the edges of the hole.
