Abstract: APPARATUS FOR TEXTILE COLOR ANALYSIS USING REFLECTED LIGHT           Abstract of the Disclosure In a textile color analyzer, a sample of textile is supported on the pad of an elevator mechanism that holds the sample against an instrument head.  The head has an opaque housing provided with a chamber having an opening therein.  A glass plate is mounted in the head and covers the opening and presses against the textile sample to provide a stable reference plane.  The head includes an illumina-ting fiber optic bundle that directs light substantially perpendicular to the textile sample.  A plurality of additional fiber optic bundles are mounted to receive diffuse light reflected from the sample.  The elevator includes a pad of translucent polyethelene material that backs up the textile sample and takes on the color of the sample so that there are no adverse effects due to light showing through the sample and reflecting from the plate.

Abstract: ABSTRACT OF THE DISCLOSURE           Capacitively coupled, transient response improving, series capacitance compensating electrostatic shields in a disc-wound winding progress inwardly from the outer portion of said winding in a tapered configuration or inwardly and outwardly in a conical-taper configuration, as the winding progresses from a high potential end.  With this arrangement a substantial reduction in the change in series capacitance is effected between the compensated and uncompensated portion of said winding which minimizes unsatisfactory voltage transient build-up at the beginning of the uncompensated or lower series capacitance portion of said winding.

Abstract: An apparatus for dispensing steel strapping material from a heavy coil thereof supported on a pallet having laterally spaced-apart elongated feet and a positioning hub for preventing horizontal movement of the coil thereon.  A horizontal turntable is rotatably driven about a vertical axis by an air motor and it includes a pair of laterally spaced-apart elongated roller conveyor tracks for respectively receiving the pallet feet for rolling the pallet to a dispensing position on the turntable coaxial therewith.  The track assemblies engage the sides of the pallet feet and cooperate with positioning bars spanning the ends of the track assemblies for limiting horizontal movement of the pallet, while a hold-down assembly cooperates with the turntable to prevent vertical movement of the pallet.  Control means controls the actuation of the air motor in accordance with the demand of associated strap-utilizing equipment.  An entry conveyor comprising track assemblies like those on the turntable may be utilized for storing a spare pallet and coil and facilitating rolling thereof onto the turntable.  Handling of the coils themselves is eliminated as the coils need not be removed from their pallets.

Abstract: CONTROL SYSTEM OF A RAILWAY VEHICLE AIR BRAKING SYSTEM Abstract of the Disclosure A condition-responsive or safety switch regulates the energizing of a first relay having two contacts that are open when non-energized.  The first contact is connected to a contact switch of a differential pressure switch and regulates and ener-gizing circuit for a second relay through a holding contact of the second relay.  The second contact of the first relay is in series with a pressure switch and connected into an energizing circuit for the second relay in such a manner that a contact of the second relay when open in the deenergized state regulates a control circuit for a brake solenoid valve.  The brake solenoid valve is in a connection between the control input and control output of an operator's brake valve.  Pressure regulating means are connected to the control putput and means for controlling pressure in the air line are connected to the control input.          The solenoid valve when in the deenergized  condition interrupts the connection between the control input and control output and establishes a throttled connection between the control input and the atmosphere.  This causes a first air tank to be connected to the control input through a first throttle check valve open-ingin such direction of flow in such a manner that the pressure in the first air tank acts upon the differential pressure switch in its closing direction against the pressure in the operator's brake valve control input.  A second air tank is connected to a second throttle check valve opening in such direction of flow to a control connection of the operator's brake valve which is vented to the atmosphere only in a position of the operator's brake valve that corresponds to full braking.  Otherwise, com-pressed air is passed,  The pressure in the second air tank acts upon the pressure switch in the opening direction thereof.

Abstract: 60.427/479 Canada TO ALL WHOM IT MAY CONCERN:        Be it known that We, GERALD HUCHITAL and JACQUES TABANOU, have invented an improve-ment in METHOD AND APPARATUS FOR DETERMINATION OF SUBSURFACE PERMITTIVITY AND CONDUCTIVITY   of which the following is a SPECIFICATION                   ABSTRACT OF THE DISCLOSURE          The disclosure is directed to an apparatus and method for determining the dielectric constant and/or con-ductivitv of earth formations surrounding a borehole.          Electromagnetic energy is generated at a first location in the borehole.  The relative attenuation and the relative phase of the electromagnetic energy are detected at second and third locations in the borehole, respectively.  The third location is spaced farther from the first location than is the second location; in other words, the second location is between the first and third locations.  The relative attenuation is preferably obtained from a first or "close" differential receiver at said second location and the relative phase is measured by a second or "far" differential receiver arrangement located at the third location.  Means are provided for determining the dielectric constant and/or the conductivity of the formations as a function of the detected relative attenuation and relative phase.  These properties are determined with improved accuracy as compared to prior art techniques because the relative attenuation and relative phase information represents the effects of formations at substantially the same depth of investigation.  In a further embodiment of the invention, the relative attenuation of the electromagnetic energy is also detected at the third location and then combined with the other information to obtain an "ultra deep" conductivity value.

Abstract: HOLD-DOWN CLAMP ASSEMBLY FOR UPPER SWINGABLE INKER OF PERFECTING PRESS                 Abstract Of The Disclosure In an offset printing press the inker is normally clamped down against the printing section so as to transfer ink from the form roll of the inker to the plate cylinder of the printing sec-tion, but upon actuation of an air cylinder to extend the rod thereof, a clamping jaw on the outer end of the rod releases its grip on a latch lever and pushes against the frame of the printing section, thereby incrementally raising the inker and effecting slight separation of the form roll and plate cylinder.  Such slight separation is not, however, sufficient to disengage drive mech-anism associated with the form roll and plate cylinder so that the form roll may continue to rotate notwithstanding the slight separation. Substantial separation of the form roll and plate cylinder sufficient to disengage the drive mecha-nism may be effected by leaving the rod of the air cylinder extended so that the jaw on the rod is out of clamping engagement with the latching lever, whereupon raising of the inker by means other than the air cylinder causes the jaw to flip the swingable latch lever to a released position as the cylinder is raised with the inker.  A reset lever attached to the latching lever is engaged and operated by the jaw as the inker and air cylinder are lowered back into position, thereby returning the latch lever to its original position where it may be clamped between the movable jaw on the rod and a stationary jaw on the body of the air cylinder so as to once again hold the inker against the printing section.
