During refining/beating of beating material there exists a need to measure more parameters than the gap, directly in the beating zone. The present invention makes this possible and it relates to a system for continuous measuring of pressure and temperature in the beating zone and the system is characterized in that a number of separate/combined pressure sensors or temperature sensors provided with...

The valve has a valve shaft (9) which is displaced against a return spring bias via an operating element (8). A valve play setting element operates between the operating element and the valve shaft. The operating element has a setting screw (11) which oscillates with the armature of the electromagnetic operating device, used for adjusting the effective length of the operating element. The setting ...

The drive includes two electromagnets, whose pole surface areas face each other at least partially, and a movable armature arranged reciprocating between these pole surface areas. The armature is held in an intermediate position using spring while the electromagnets are turned off. The armature is brought, at switching on of one of the magnets, into one of two end positions, at least nearby the po...

A blade (10) of the bat has a rubber face applied via an exhaling adhesive. It is placed in a container, and this is charged with excess pressure maintained over a period. The pressure is generated by compressed air, and is approximately 1.5-2.5 bar. The container has an upper and a lower part (20, 23) connected via a releasable closure (27), and is pressure proof. It has a valve (30) for connecti...

A resistive exercise suit has a resistive shirt and resistive exercise trousers. The resistive exercise shirt uses tension bands on sleeve fronts and backs and attachment to central elastic blocks on the front and back of the shirt. Both the tension bands and the elastic blocks are incorporated into the shirt and provide means by which resistance can be made against arm movements. Thumb stirrups f...

To be able to produce metal melts using any metal carriers incurring in metallurgical practice as the charging materials, namely in the most diverse quantitative compositions, a plant for producing metal melts is provided with the following characteristic features:an electric arc furnace vessel (1) provided with one charging opening (11, 21) for a metal melt and/or scrap and/or direct reduced meta...

Um bei einem chirurgischen Rohrschaftinstrument mit einem Schaft, an dessen distalem Ende mindestens ein Werkzeug an einem Halter angeordnet ist, der seinerseits am Schaft festgelegt ist, und mit einer den Halter teilweise abdeckenden Kunststoffummantelung, eine bessere Festlegung der Kunststoffummantelung am Halter zu ermöglichen, wird vorgeschlagen, dass die Kunststoffummantelung an ihrem Rand V...

A curved mirrored surface (78) is used to collect radiation scattered by a sample surface (76a) and originating from a normal illumination beam (70) and an oblique illumination beam (90). The collected radiation is focused to a detector (80). Scattered radiation originating from the normal and oblique illumination beams may be distinguished by employing radiation at two different wavelengths, by i...

A method and apparatus (1003) encodes identification information into a stream of digital data representing an object. The digital data representing an object is modified to add embedded identification information (1005) into the data. This modification is done such that the resultant changes to the object are not objectionable to the user. By comparing the original digital data to the modified da...

A photodetection system and related circuitry designed to sense the intrusion of an opaque object in a light plane. Upon sensing the intrusion, the system quickly initiates a machine-stopping sequence prior to the opaque object coming into contact with the machine while that machine is operating. The system comprises a SYSTEM microcontroller and a WATCHDOG microcontroller, both of which operate an...

An on-line, fiber-optic based apparatus for monitoring the concentration of a chemical substance at a plurality of locations in a chemical processing system comprises a plurality of probes, each of which is at a different location in the system, a light source, optic fibers for carrying light to and from the probes, a multiplexer for switching light from the source from one probe to the next in se...

A novel polyester polymer containing 9,9-bis[4-(2-hydroxyethoxy)phenyl]fluorene as the diol component. It has good transparency and thermal resistance, small optical anisotropy and excellent moldability, dimensional stability and chemical resistance, thus being useful in the industrial fields including optical material, fiber, film and sheet.

A security system having a two way wireless keypad which operates in a particular manner for improved operation. The keypad processes information to effectively reduce communications between the control panel and the keypad. The keypad selectively activates and deactivates a transmitter and receiver arrangement for power conservation reasons. The system provides confirmation of communications betw...

The method involves inspecting an object (10) using a light source (12) and a camera (16). A contrast pattern (14) of transparent and non transparent areas is placed between the light source and the object. Faults are recognized from a reduction in the contrast of the pattern image after passage through the object
