Abstract: VITAL TRACK CIRCUIT WHEEL DETECTOR            Abstract of the Disclosure A vital, or fail-safe, track circuit wheel detector for detecting the presence and position in a given detection zone of wheel-axles on railroad cars; in order to provide the requisite fail-safe indication, the operation of the system relies on a sensing means which produces two distinct output signals.  The sensing means includes a biasing arrange-ment for providing, even in the absence of wheel-axles, a steady output signal derived from the path of normal feed current flow.          This bias signal is countered or opposed by a wheel sensing signal from the same sensing means responsive to flux level changes resulting from the presence of particular directional components of wheel-axle shunt current, whereby a dip or net reduced signal is effectuated; in the case of open circuit conditions, the output indication goes to zero when there are no wheel-axles in the detection zone.

Abstract: ABSTRACT OF THE DISCLOSURE     The  invention  is  primarily  concerned with  a  sandwich material  (55) made of sheets based on paper.   This material is substantially comprised of a sheet (42) of corrugated paper (44) forming one or several layers.  An intermediate paper sheet (31) is bonded to the corrugations of the sheet 42.  A film (29) of a thermoplastic compound adheres physically as the result of an extrusion to the outer side of the intermediate paper sheet (31). The process for manufacturing this material consists firstly in extruding  a  film  (29)  of  thermoplastic  compound  on  the intermediate paper sheet (31), and then in bonding the web (27) of protective layer thus obtained on the corrugations of the sheet of corrugated paper (42).   The invention is remarkable in that these operations are carried out on a standard machine for manufacturing corrugated paperboard.  However, on the one hand an adhesive setting instantly at room temperature is used,  and on the other hand the various heating elements used to bring about the  setting  of  adhesives  polymerizing through  an endothermic reaction are kept switched off.   The invention is particularly useful for making furniture or wall panels.

Abstract: Abstract of the Disclosure A laser beam scanning device is disclosed and which includes an optical system that is mounted on a carriage which is movable back and forth along a linear path in front of a target area and which is parallel to the optical path of a projected laser beam. The lens system includes a component on the carriage which is arranged in the optical path for the laser beam and serves to project the laser beam along a second optical path toward the target area and which is normal to the first optical path.  The optical system also includes a focusing lens on the carriage which is arranged in the second optical path for focusing the laser beam on the target area.  A pair of lenses that are mounted on the carriage as part of the optical system are arranged to form a collimating telescope so as to expand and then collimate the laser beam light for delivery to the focusing lens.  The collimating lens of the pair is movable relative to the carriage along a path which is normal to the optical path so as to thereby shift the focal point in the target area.  The device utilizes stepping motors for moving the carriage and collimating lens.  The device is shown as a component of a laser marking system where the laser system and scanning device are controlled by a computerized control system.

Abstract: ABSTRACT OF THE DISCLOSURE:      A roadway milling  machine includes a hollow, cylindrically walled, shaft mounted  imperforate drum having tungsten carbide tipped steel cutting tools supported in tool holders extending generally radially outwardly from the cylindrical surface of the drum. The drum is moved over a roadway to be milled  and is rotated on its shaft to bring the cutting tools into operative contact with the roadway.  Water is fed into the drum along a water access opening provided along the axis of the drum shaft.  The water flows through openings provided in the cylindrical drum wall toward each cutting tool.  The water impinges upon and cools the cutting tools.  In order to limit the flow of water from the drum to the cutting tools and, at the same time, to prevent the necessarily small openings from clogging up, large openings are provided through the cylindrical drum wall and well into the tool holders which  extend integrally outwardly from that wall. A transverse opening  through each tool holder is open to the tool holder large radial opening in the tool holder.   This transverse opening is partly closed with a bolt or other rod-like structure. The minimum cross-sectional area of the bolt is less than that of the transverse opening and the bolt is free to vibrate or otherwise move under the impetus of the shock to the tool and tool holder as the tool strikes the roadway on each rotation of the drum.

Abstract: PRECISION DISPLAY POSITION DESIGNATION SYSTEM          USING COARSE TOUCH PANEL INPUT                         ABSTRACT A display includes circuitry for locating a cursor (50) or similar position designation on a display (22) which might, for example, represent a geographical area on a keyboard.  A touch panel array (24) of photo-transistors (48) and light emitting diodes (46) provides a matrix of light beam paths across the face (12) of the display (22), or a separate detection unit, which are interrupted when a pointer such as a finger points to a particular location on the display (12) and inter-rupts the light beams which is a coarse indication of a new cursor position.  The fine position of the cursor (50) is calculated by using both the available positional data and also velocity corrections and/or acceleration based upon movement of the finger from the prior location to the new position.  Initial transient position desig-nation errors are eliminated by delaying until the array of light beams have been interrupted for several scan intervals at which time the fixed position is established or "jumped to"; and terminating transient errors are eliminated by deleting the last few position indications just prior to when the array of beams has remained uniterrupted for several scan intervals.
