Abstract:
The present invention encompasses an improved immunoassay method which involves the simultaneous transfer of multiple antigens onto a single solid support. The antigens which may be utilized by this method may be either naturally or recombinantly produced and may be purified on a variety of electrophoresis gels. This method is particularly useful to provide an extremely sensitive multiple component assay using essentially pure antigenic polypeptides capable of detecting the presence or antibodies to HIV-1 or HIV-2 viruses in infected patients.
Abstract:
An immunoassay which is capable of simultaneously detecting any desired number of antigens of one infectious agent, or combinations of antigens of several infectious agents, or any desired number of immunoglobulins of one infectious agent, or combinations of immunoglobulins of several infectious agents on a single solid support. A test sample is contacted with a solid support on which one or more antigens are immobilized as discrete test sites. Antigen-antibody complexes are formed and detected on the solid support.
Abstract:
A precision force transducer having a spring element (1) whose load-dependent deflection is converted into an electrical signal by means of strain gauge elements (10). The spring element (1) is made of a precipitation-hardenable nickel-based alloy with a nickel content in the range of 36 to 60 percent and a chromium content in the range of 15 to 25 percent. The strain gauge elements (10) are composed of a polymer-free layered film system. This makes it possible to produce a precision force transducer that features great accuracy, low creep and low moisture sensitivity.
Abstract:
A measurement device (10; 110; 210) and associated seating arrangement, in particular for measuring a weight acting on a vehicle seat, that includes: a force transmission element (12; 112; 212), which is connectable to a first unit, preferably a vehicle seat, and a measurement assembly (14; 50; 114; 214), which is rigidly connectable to a second unit (80), preferably a vehicle body part. The force transmission element (12; 112; 212) is pivotable about at least one axis around the measurement assembly (14; 50; 114; 214).
Abstract:
A force sensor with two force input elements to which the force to be measured and the support force are applied. The two force input elements are substantially rotationally symmetrical and are axially spaced apart, and the force to be measured and the support force are applied in a radial direction. A spring element, arranged axially between the two force input elements connects these elements and its load-dependent deformation is converted into an electrical signal. A substantially tubular cover connected to one of the two force input elements surrounds the spring element. The cover surrounds a portion of the other force input element, forming a circumferential gap. The cover has an inwardly projecting constriction that is spaced apart by a small axial distance from an opposite shoulder on the other force input element.
Abstract:
The present invention provides a a headlight operable as a running light of a vehicle and, in particular, as a headlight of the vehicle for selectively projecting a low and a high beam. The headlight includes a reflector having a light source disposed therein. A beam position adjusting device operates to move the light source between its low beam position and its high beam position. The beam position adjusting device includes an electric powered drive motor and a displaceable interconnecting element interconnecting the beam position adjusting device and the light source. The device also includes a motion translation element for translating the drive output of the drive motor to displacement of the displaceable interconnecting element, the beam position adjusting device being operable to dispose the light source in its high beam position. A return movement device automatically biases the light source to move to its low beam disposition when the drive motor is not powered.
Abstract:
A lop loaded balance with a load receiver (1, 2, 3) connected by at least one upper (11) and at least one lower guide rod in the form of a parallel guide to a system carrier (4) fixed to the housing, which load receiver, guide rods and system carrier are manufactured from one piece. The system carrier (4, 5, 6, 7) is designed as a frame. The frame-like system carrier is completely surrounded by a second frame (14, 15, 16, 17) supported on the balance feet and that both frames are constructed in a one-piece manner and are connected to one another in such a manner that twistings of the one frame are transferred as little as possible onto the other frame.
Abstract:
In a motor-driven pump unit for a high-pressure cleaning apparatus, where the cleaning fluid supplied by the high-pressure pump is conveyed through the housing of the motor so as to cool the motor, in order to improve the cooling characteristics and in order to reduce the dimensions of the motor-driven pump unit it is proposed that a fan wheel, which is driven by the motor and which directs a cooling air stream towards the motor housing, be disposed at the end of the motor opposite the pump, and that the fan wheel and the cooling surfaces of the motor be designed in such a way that an adequate cooling of the motor is achieved by the air stream cooling alone when the pump is not conveying any cleaning fluid to the cleaning apparatus or, in other words, is pumping the cleaning fluid only in circulation.
Abstract:
A nozzle for spraying a medium under pressure has a selectable form of jet. A knife edge body is rotatably mounted in front of the outlet from the nozzle bore, and has a front knife edge which breaks the jet from the bore into a spray mist when that knife edge is rotated into the jet and a rear knife edge which spreads the jet to a fan-shape when it is rotated into the jet.
Abstract:
A top-pan scale with a scale pan which is supported on at least one force transducer (7) of a force measurement system (5) and with a corner load sensor which outputs a signal if the weighing goods are positioned eccentrically on the scale pan. The corner load sensor (10) has a flat underside via which it can be placed on, or attached to, the scale pan or a bottom pan of the scale. The corner load sensor also has a flat upper side on which a scale pan (4) can be placed or attached. The corner load sensor (10) is connected to a positionally fixed electronic processor (22) via a force-feedback-free connection (21). Embodiments of the corner load sensor can therefore be used for a wide variety of scale designs and can be retrofitted easily.
