Abstract:
A blood lancet device for taking blood for diagnostic purposes, having a housing with an exit opening for the lancet, a lancet guide for guiding the puncturing and return movement of the lancet, a spring drive for movement of the lancet and a stop by means of which the lancet is held in a position remote from the part of the body from which blood is to be taken. In the region of the exit opening for the lancet, a release element is present in the housing, the release element being in operative connection with the stop.
Abstract:
A composition comprising a polyester, a brominated flameproofing agent for said polyester and 0.5-20 weight percent, preferably 1-8 weight percent, of an epoxy resin; a process for improving the decomposition behavior of a polyester composition containing a brominated flameproofing agent which comprises adding to said composition an epoxy resin an amount of 0.5 to 20 weight percent.
Abstract:
This specification describes transferring a partial block of data with first and last words that are partial words from a processor and storing it in a memory protected by an error correcting code that requires the words to be stored in the memory as whole words. Prior to the initiation of the transferring and storage procedure, the memory is accessed and data words corresponding to the partial words in the partial block of data are fetched and placed in registers. Thereafter, during the transferring of the partial words, the fetched words are combined with the partial words to generate full words. Error correction check bits are added to these generated full words and the combination is stored into the memory.
Abstract:
A process and apparatus for forming objects of thermoplastic material by deep-drawing in which portions of a foil are cut to a size appropriate for each object, and are then freely supported while heating to the desired temperature. After heating the cut-out portions are tensioned about the edges thereof for the deep-drawing step. Modifications include multiple stations for heating and deep-drawing and means may be provided for deep-drawing the foil into a permeable container so as to line it with the deep-drawn thermoplastic material.
Abstract:
A device for stimulation via electric and magnetic fields is provided. The autonomic/vegetative nervous system can be controlled by signals in the frequency ranges of 0.05 to 0.15 Hz and 0.15 to 0.30 Hz, respectively. By addition of characteristic sinusoidal oscillations between the head and a peripheral area with the corresponding low-frequency sympathetic or parasympathetic control frequency as base oscillation and with application-typical EEG frequencies and higher-frequency sinusoidal oscillations in the range of ca. 250 to 1500 Hz, characteristic stimulation programs are established. These are applied by field applicators in the upper body area and in the lower body. The associated mat applicators distribute field energy. The field applicator is equipped with a combination of a magnetic-field-generating coil arrangement and an electrode arrangement generating the electric field. The electrode generating the electric field can at the same time be designed as a magnetic-field-generating coil.
Abstract:
The refrigeration compressor is a double-acting refrigeration compressor, comprising a piston which is freely guided on two cylinder sections that are opposite each other and that cannot be moved relative to each other, and which has a flow channel that extends internally through the piston, wherein each cylinder section and the piston have at least one check valve along the flow channel, wherein the check valves are arranged in such a way that the flow directions thereof are oriented in the same direction.
Abstract:
A gas release valve to be mounted in an access port of a battery cell includes a housing, the upper side of which is closed by a lid. The lower side of the lid has an opening leading into the battery cell and is in communication, via degassing passageways closed by an elastic sealing element, with at least one vent provided in the lid. The elastic sealing element is a preloaded non-return element, the inner surface of which is urged into sealing contact with a seat provided in the housing by its own elasticity and, in addition, by a pressure differential with the outer pressure that acts through the vent against the outer surface of the sealing element.
Abstract:
In a system made up of battery units (2) and corresponding terminal connectors (10), the battery units may be combined in different ways in order to obtain larger battery groups. Each battery unit (2) has one surface that forms a terminal area (3) and that includes two terminals (6, 7), this surface having longitudinal edges (4) with a length (a), and lateral edges (5) with a width (b), (a) being equal or nearly equal to (2b), and the distance of each terminal (6, 7) to the longitudinal edges (4), as well as to the adjacent narrow edge (5) being equal or nearly equal to (b/2). A terminal connector (10) connects two terminals (6, 7) of adjacent battery units (2, 2′) and includes an electrical junction (12) having two connection points (16, 17) at its ends and a span equal or nearly equal to (b). Vertical connectors may be provided to interconnect terminals of battery units belonging to different layers of stacked up batteries.
Abstract:
The invention relates to a lifting device for raising the hood (20) of a motor vehicle during a collision with a pedestrian. The device comprises a retaining member (10) for connecting the hood (20) to the vehicle bodywork (14) and a pyrotechnic explosive unit (16) for detaching the retaining member (10). To guarantee a reliable operation, the device is equipped with lifting means (18) for raising the hood (20) into a collision position, the means being actuated by the energy of the explosive unit (16) released during the detachment of the retaining member (10).
