A hybridoma is provided which yields a monoclonal antibody which binds to an epitope on an unreduced, nonenzymatically-glycated plasma protein, and which is substantially free of cross-reactivity with the corresponding non-glycated plasma protein.

A flexible interior element (7) for securing the foot of a skier inside a rear entry ski boot. The respective ends of the element are attached at two spaced points (8, 9) on the rear portion (4) of the upper, and form between these ends a loop which passes over a return element (15), which is displaceable by a tension adjuster so as to vary the length and hence the tension of the loop.

PURPOSE:To rigidly connect tapes without local increase of the thickness of the tapes by exfoliating and removing the kraft sheets at the ends of bot tapes to be bonded, butting the ends of the tapes, contacting and bonding a connecting plastic film to the portion to be removed. CONSTITUTION:Kraft sheets 3, 3' of one sides of one ends 4, 4' of composite tapes 1, 1' are exfoliated and removed to ex...

Apparatus for spinning yarn from roving including a spinning frame with spinning units arranged thereon. The roving to be drawn is fed from a common double-roving bobbin to each of two neighboring spinning units, further referred to as spinning units pair. At least one stopping device is assigned to each of the spinning units of the spinning units pair, to stop and release again the roving feed to...

A thermoplastics container comprises a body portion 1 formed from a flat sheet by bending the sheet to produce a tube and welding together the ends of the sheet by hot- plate welding. The sheet ends are preferably butt-welded. End portions 2, 3 are attached to the body portion 1 by welding or adhesive; one end portion may be injection-moulded directly onto the body portion. The body portion can be...

A pipe or fitting tubular section (17) is at first deformed so as to obtain at least a radial wall, substantially perpendicular to the pipe axis, and having, as regards the thickness, such a height that its buckling limit load is inferior to its combined bending and compressive limit load; then said pipe is deformed by substantially radial forces acting on a zone adjacent to said radial wall which...

PURPOSE:To improve working efficiency, by setting a level setter at a constant level output equivalent to a specified temperature of a heat block, comparing said output with the output of a temperature detector, starting the device by the presence or absence of the output without waiting time. CONSTITUTION:A heater 2 is embedded in the heat block 1 which heats a sample and the temperature detector...

In the hearing aid, the sound transducers (2, 3) are arranged in accommodation parts (5, 6) which in each case exhibit a compartment for accommodation the sound transducers (2, 3) which can be closed by the housing (1) or a separate part (11, 12) to form a soundproof chamber (13, 14) in order to shield the microphone (2) against airborne sound emitted by the receiver (3). On the outside, the accom...
