Abstract: A stopper rod for controlling the flow of molten steel from a tundish has a metal carrier element partly received in an internal passageway of the stopper rod, the carrier element compressing sealing means between a frustoconical undersurface of a laterally enlarged portion thereof and a complementary seating surface of the stopper rod passageway, there being an insert threadedly engaged with one of the carrier element and stopper rod body at a position above a laterally enlarged portion of the carrier element, with further sealing means disposed between said insert and the carrier element. Preferably the insert is a nut screwed down onto a washer which compresses the further sealing means.

Abstract: The invention is directed to a child car seat, composed of a) a seat shell, comprising a bottom sitting region with at least one bottom stand surface to be stood on a seat of a vehicle, a backrest region extending upwardly from the sitting region and having at least one outer surface to be leaned against the backrest of the vehicle seat, and lateral surfaces, for example lateral armrests, shoulder supports and/or head supports, for limiting the lateral range of movement of a child, at least that portion of the backrest region that comprises a rear leaning surface being rigidly connected to the sitting region comprising a bottom stand surface, and b) a rather two-dimensional seat element, comprising a sitting surface and/or backrest that is/are disposed on the inner side, turned toward the child, of the seat shell and is/are adjustable with respect thereto in terms of inclination and position and is/are lockable in a plurality of different inclinations and/or positions by means of a manually operable device o

Abstract: A pressure sensor device with a housing including an electrical contact plug section which provides a pressure channel for a pressure sensor accommodated in the housing. The housing is constructed in multiple parts comprising a first housing section with the contact plug section seated in one piece thereon and a second housing section forming the pressure channel constructed to act in conjunction with the first housing section. A pressure recording unit built in modular fashion and carrying the pressure sensor is constructed in such a way that in an operationally useful state of connection of the first and of the second housing section the pressure sensor unit is fixed between sections of both housing sections. The pressure recording unit possesses a connecting unit which is connected in cordless electrically conductive manner to a contact pin held in the contact plug section.

Abstract: This invention involves a child's car seat with a seat surface, a back rest, optionally with side arm supports and/or head supports or rests, and with side guides for the insertion of the belt of a car, and with at least one device for the automatic tightening of the car belt, and with a device for adjusting the inclination of the child's car seat relative to the vehicle's own seat. The device for the automatic tightening of the car belt is located in the area of a belt provided in the top area of the back rest guide and acts at the same time on the shoulder belt and the waist belt. There is further at least one device for fastening the car's shoulder belt immovably with respect to the child's car seat.

Abstract: A surface protection film comprising a transparent backing of polypropylene or propylene-ethylene copolymer, which comprises a light stabilizer, and a self-adhesive composition of polyethylene-vinyl acetate (EVA) having a VA fraction of from 40 to 80% by weight and a melt index MFI in accordance with ISO 1133 (A/4) of from 0.5 to 25 g/10 min at 190° C. and 2.16 kg, which is blended with from 0 to 35% by weight of a polyether of the form XO—[(CH2)4—O]—Y  (1) or XO—[(CH(CH3)—CH2—O]—Y  (2) having a weight-average molecular weight Mw of from 200 to 100,000 g/mol, X and Y being selected from the group consisting of H—, (CnH2n+1)— where n is from 1 to 20, CH2═CHCO—, CH3CH(NH2)CH2—, 2,3-epoxypropyl- or C6H5—CO—, CH2═C(CH3)—CO—.

Abstract: A rotor tie bolt nut includes a nut body having a threaded center hole therein; a first peripheral surface on one side of the center hole that spans the center hole and extends in opposite directions to define a pair of wing sections; and a pair of buttress sections supporting the wing sections; the buttress sections having second and third peripheral surfaces connected to opposite ends, respectively, of the first peripheral surface, and to each other by a radiused surface on an opposite side of the center hole.

Abstract: A method for analyzing a gaseous medium with respect to a component having a characteristic absorption frequency spectral line, including the steps of generating microwave radiation at a selected frequency, generating a first Stark voltage selected to have a value such that a reference signal produced by subjecting the component to the microwave radiation and the first Stark voltage has a zero passage, resulting from the change in polarity between the spectral line and the Stark voltage lines, at a frequency coinciding with the characteristic absorption frequency spectral line, and regulating the microwave radiation frequency as a function of frequency shifts of the zero passage of the reference signal.

Abstract: Enzymatic conversion of polysaccharides to monosaccharides or lower molecular weight polysaccharides is carried out by means of an enzyme derived from B. megaterium which exhibits alpha-amylase activity.

Abstract: A circuit is disclosed for fault-monitoring a microprocessor. The circuit includes an oscillator having an output signal of the same frequency as a test signal output of the microprocessor. The circuit also includes a binary counter. The microprocessor test output is coupled to the reset input of the counter and the oscillator is coupled to the counting input of the counter. The counter counts when the test signal does not correspond in frequency to the oscillator signal. A lower order output signal of the counter is used as a reset for the microprocessor and a higher order output of the counter is used to generate a fault indicating signal if the microprocessor has not resumed correct operation and to inhibit the microprocessor. The oscillator is coupled to the counting input of the counter through a logic circuit. The two outputs of the counter are coupled to another logic circuit which supplies the reset and inhibit signals to the microprocessor.
