Abstract:
A lock tongue for safety belts with a belt strap of the safety belt being adapted to pass through the lock tongue and be firmly attached to the belt strap so as to be safe against displacement at a certain location of the belt strap due to a loop-around friction occuring under load. The attachment is effected by repeated deflection of the belt strap by means of a component separate from the lock tab or tongue cooperating with the later. The lock tab or tongue includes two passage openings which are separated from each other by a central web, with the passage openings being adapted to accommodate the belt strap. A clamping bracket may be attached, preferably in a releasable fashion, into one of the passage openings. The clamping bracket bridges the passage opening and extends along an entire longitudinal extension of the passage opening and rests on both sides in marginal zones of the lock tab or tongue adjoining the narrow sides of the passage opening, wherein the clamping bracket serves for supporting the belt strap extended therearound.
Abstract:
Method for implanting and subsequently removing mechanical implants of an Ni-Ti or a Ti-Nb alloy material which exhibits the memory effect which occurs due to heating of the implant to a temperature above the specific temperature for the alloy material. The memory effect is actuated by heating the implant after implantation of same in the living tissue, and upon completion of the healing process, the implant is substantially returned to its shape upon implantation by cooling it to a temperature below the temperature which actuates the opposite memory effect to facilitate removal.
Abstract:
An arc quenching arrangement is disclosed for a circuit breaker equipped with stationary contacts and a contact bridge having respective sides facing toward and away from the stationary contacts. The contact bridge is movable between closed and open positions to respectively contact and separate from the stationary contacts, whereby an arc is formed as the contact bridge moves away from the stationary contacts to the open position. The arc quenching arrangement quenches the arc and includes an arc guide having a longitudinal axis. The arc guide is located adjacent the side of the contact bridge facing away from the stationary contacts and is positioned such that the longitudinal axis thereof extends in a direction substantially parallel to the longitudinal dimension of the contact bridge. The arc guide has respective end portions bent in a direction away from the contact bridge; these end portions are located in the vicinity of the respective ends of the contact bridge. Each of the end portions is bent so as to form an acute angle .alpha. with the longitudinal axis in the range 15.degree.
Abstract:
A filling neck to feed fuel into a motor vehicle tank using a filling nozzle, exhibiting the following features: a slotted drive ring comprising an insertion portion conically tapering toward the vehicle fuel tank, the cross-sectional constriction being less than the filling nozzle's cross-section; the drive ring, facing the fuel tank comprises, on at least one side of said gap, a locking segment; the drive ring is configured in floating manner in a cup-shaped housing portion of the filling neck, the outside diameter of said ring being less than the inside diameter of the cup-shaped housing portion; a sealing element is associated with the distal end of the drive ring, blocking access to the tank in its closed position; the drive ring's locking segment engages and keeps the sealing element in the locked position, and moves into the open position when said drive ring is expanded by the filling nozzle.
Abstract:
The present invention to an active muffler for an exhaust gas system of an internal combustion engine, in particular in a motor vehicle, includes a multi-shell housing having a pot-shaped top shell and a pot-shaped bottom shell, a funnel-shaped sound conducting body, which is inserted into the bottom shell and has a connection passing through the bottom shell and out of the housing, a loudspeaker, which is situated in the top shell and is attached to a flange section of the sound conducting body at a distance from the connection, such that a free inside cross section of the sound conducting body surrounded by the flange section is closed with an airtight seal, and a bypass through which an interior space of the top shell is connected to an interior space of the bottom shell so they communicate.
Abstract:
The invention relates to a method for producing polymers, in particular synthetic nucleic acid double strands of optional sequence, comprising the steps: (a) provision of a support having a surface area which contains a plurality of individual reaction areas, (b) location-resolved synthesis of nucleic acid fragments having in each case different base sequences in several of the individual reaction areas, and (c) detachment of the nucleic acid fragments from individual reaction areas.
Abstract:
The invention relates to a connecting strip (1) for telecommunications and mid-range communications technology, comprising a housing (2) and at least two contact elements (11), wherein the contact element (11) comprises a first contact (12) for the connection of wires or cables and a second contact (13) for contacting a printed circuit board, the second contact (13) taking the form of a press-fit pin contact or a tuning-fork contact, and in which the first contact (12) is aligned towards the upper side (3) of the housing (2), and the second contact (13) is aligned towards the underside (4) of the housing (2), the first contacts (12) being arranged laterally offset from the longitudinal axis (L) of the housing (2), and on the opposite side at least one fin (8) being arranged so that between the first contacts (12) and the fin (8) a trench (9) is formed, the contact element (11) being constructed with a bracket (15) positioned above the second contact (13), aligned towards the upper side (3) of the housing (2), and arranged underneath the trench (9).
Abstract:
The present invention relates to arrays of biochemical and/or biofunctional elements such as nucleic acids (oligonucleotides, for example) or other biomolecules on a carrier surface and methods of producing such arrays using photoactivation of predetermined areas for synthesis using an illumination matrix that is computer-controlled to generate an exposure pattern. This exposure pattern can be adjusted and monitored by computer using a light sensor matrix, for example a CCD matrix, to allow precise, controlled illumination of specific regions and therefore attachment of array building blocks to those specific regions. The methods and compositions of the invention permit spatially resolved photochemical synthesis of polymer probes on a carrier.
Abstract:
A method is provided for the detection of an immunoglobulin which binds to an allergen in a sample, whereby one or more allergens are immobilized on a microarray chip after which the sample is incubated with the immobilized allergens so that immunoglobulins which are specific for the allergens bind to the specific allergen after which the immunoglobulins which are bound to the specific immobilized allergens are detected, as well as a method for in vitro diagnosis of allergies in a patient.
Abstract:
The present invention relates to a microfluid reaction carrier intended for the purely fluid or light-controlled synthesis or analysis of oligomers or polymers. The reaction carrier comprises a structure of flow channels for the fluids, while supply channels and discharge channels parallel to the latter form an angle relative to the plane of the structure of the flow channels (reaction areas).
