The probe (1, 1') contains a mea-suring unit (14) which incorporates a temperature sensor (17) and which is in communication with the test liquid via a supply bore (13).  The upper part of the measuring unit (14) forms a condensation zone (15) which is con-nected to the atmosphere via discharge openings (16).  On ebullition of the test liquid, a bubbles or foam boiling zone (22) is formed directly on top of the surface (21) of the liquid, and on top of the zone (22) a condensation zone (15) is formed, out of which the condensate flows off to the outside.  The temperature in the bubbles boiling zone is measured by means of the temperature sensor (17).            (Fig. 1)

Abstract: ABSTRACT OF THE INVENTION       Multiple small-article receiving cassettes are provided for removably mounting on the upper surface of an inclined support.  A drum housed within each cassette is rotated by connection with the drive shaft of a motor projecting through the support.  The disk-like bottom of the rotatable interior drum of the cassette is undercut to form a circumferential series of radial and angularly spaced article receiving slots with the innermost end of the slots in overlying relation with respect to an outlet opening formed in the bottom stationary plate of the cassette.  A second outlet opening, located in the upper surface of the support, is aligned with the opening in the bottom of the cassette.  Upon proper rotation of the drum, articles placed within the cassette will travel along the receiving slots to their innermost end and then drop through the two outlet openings and into a dispensing chute.  A single electrical control means and single motor is used with numerous different cassettes for dispensing different drugs.  The motor is rotated until a desired number of pills is dispensed and is then stopped.

Inventor: BLAZEVIC DAVID T
IPC: B21B15/00
Filed: 1987-09-21
Granted: 1991-12-17
Abstract: ABSTRACT    A system for processing steel strips in a hot strip mill includes an apparatus and method for removing the oxide layer in the finishing mill process such that the final thickness of the oxide layer is much less than previously possible.  In order to reduce the thickness of the oxide layer, the invention provides for the removal of oxide scales from the surface of the steel strips at a distance in front of the working rolls of the finishing mill that minimizes the time the strip is exposed to ambient conditions after it is descaled and before it is received between the pair of working rolls.  By minimizing this exposure time, the thickness of the oxide layers in the finished strips is substantially reduced,

Title: Double-layered fabric for paper making machines having a coarse-structured bottom side and a fine-structured forming side
Inventor: VOEHRINGER FRITZ
IPC: D21F/
Filed: 1987-10-14
Granted: 1993-05-25
Abstract: ABSTRACT           Double-layered fabric for paper making machines having a coarse-structure bottom side and a fine-structure forming side.  Forming fabrics of this kind have a set of warp strands and at least two sets of weft strands which are interwoven at least in a six-shaft repeat, so that a weft strand set on the bottom side constitutes a primary wearing plane and the remaining weft strands or sets of weft strands are arranged on the forming side and may differ from each other in respect of diameter and/or float lengths.  Modern, fast and high-performance but more sensitive printing processes require highest-quality paper grades.  However, so far the above-mentioned quality features could not be optimized for double-layered fabrics.  The double-layered fabric is improved in such a way that it meets highest demands in respect of a fine-meshed structure on the forming side and a coarse-meshed structure on the bottom side as well as its wearing characteristics.  This is achieved in that at least portions of the bottom-side weft strands constitute multi-strands each formed of at least two closely adjacent strands which are tied up by different warp strands.

Filed: 1987-10-22
Granted: 1992-03-17
Abstract: Abstract:    The invention relates to a worm mower for cutting blade material of all types.  The mower has a mowing worm that turns at a high peripheral speed and combines the following features: the helical angle (a) of the worm is less than the angle of friction (gliding angle) of the worm for the material to be cut.  Moreover, the circumference of the worm features in the axial direction a continuous cutting surface that runs either parallel or at an angle to the axis of the worm or in a stepped fashion.  The mower works with a clean cutting operation, even at low speed.

Title: Pilot-controlled pressure-limiting valve
Inventor: WIDENMANN KARL
IPC: F16K17/10
Filed: 1988-01-29
Granted: 1991-01-29
Abstract: ABSTRACT          Pilot-controlled pressure-limiting valve A compact pressure-limiting valve is provided for optional attachment to a water-conducting device which for this purpose comprises a flange which matches the connecting flange of the pressure-limiting valve and which can be closed with a closure-plate when the pressure-limiting valve is not required.  A compact unit providing high respone speed of the pressure-limiting valve is achieved by a particular relative arrangement of the main piston and the pilot valve piston and by short and loss-free flow connections in the interior of the pressure-limiting valve.  In spite of the high response speed and the compact constructional form the pressure-limiting valve is distinguished by a large flow cross-section for levelling pressure peaks.

Title: Cursor interface for waveform displays
Inventor: SLAVIN KEITH R
IPC: G01R13/20
Filed: 1988-02-29
Granted: 1992-06-09
Abstract: Abstract of the Disclosure A cursor interface for a waveform display provides for movement of a waveform relative to a first cursor.  When the first cursor overlies a desired point on the waveform, the cursor is locked to the waveform by transforming the cursor coordinates from display coordinates to waveform coordinates.  The waveform may then be moved together with the first cursor relative to a second cursor.  When the second cursor overlies another desired point on the waveform, a measurement value is displayed indicating the difference in positions on the waveform of the cursors.  The cursors may be centered independently, and when locked to the waveform the result is to correspondingly move the waveform.
