Abstract: An improved apparatus for cutting an enveloped body, which consists of an assembly having at least three circumferentially disposed cutting members with at least two sliding surfaces. The cutting members are assembled in sliding contact with each other such that the sliding surfaces of adjacent cutting members are slidable along each other so as to form or close a central opening surrounded by the cutting members. The opening is opened and closed for cutting the enveloped body passing therethrough. One sliding surface of a cutting member forms a convex surface, and the other sliding surface forms a concave surface complementary to the convex surface, so that the convex surface of a cutting member slides on the concave surface of an adjacent cutting member.

Title: Remote tracking system particularly for moving picture cameras and method.
Inventor: PARKER JEFFREY L
IPC: G01B11/26
Filed: 1991-05-31
Abstract: The system includes a mobile remote unit sensitive to infrared (IR) signals transmitted by a base or stationary unit and an IR transmitter which is placed behind a rotating lens whose position at any time is known with precision resulting in the IR signal being "scanned" across an area. The remote unit detects when the peak strength of the signal occurs and provides this data via an RF signal to the base unit wherein the exact effective angle between the axis of the IR signal and the remote unit creates an error signal used by the base unit to position the camera mounted thereon. Transmitters for TILT and two PAN positions, PAN 1 and PAN 2, are used to include range calculations for ZOOM functions. Command circuitry to override the automatic tracking function is provided in each of the units.

Abstract: A method for improving the aging resistance of the sidewalls of retreaded tires is provided. The method involves the steps of treating the surface of the sidewalls of the worn tire to be retreaded with an aqueous solution or dispersion containing a film-forming polymer and an antiozonant, retreading the treated tire and then curing the treated retreaded tire thereby causing the antioxidant to migrate into the inner portion of the sidewall. 
     The method of the invention is particularly useful for improving the aging resistance of the sidewalls of worn truck and bus tires which are conventionally retreaded several times.

Abstract: A presensitized plate for use in making a lithographic printing plate comprises a substrate provided thereon with a light-sensitive layer formed from a light-sensitive composition comprising a diazonium polymeric compound having two kinds of specific repeating units and a lipophilic polymeric compound having an acid value of not less than 20 and less than 250. The presensitized plate can provide a lithographic printing plate having excellent printing durability since the diazonium compound used has a high molecular weight. Moreover, since the diazonium compound has alkali-soluble groups and the lipophilic compound having an acid value of not less than 20 and less than 250 and easily soluble in an alkaline water is used as a binder, the presensitized plate has good developability and can provide a lithographic printing plate free of background contamination.

Abstract: The thickness of the layers of rubber covering the steel belts within a tire can be measured by transmitting a microwave signal toward the outer surface of the tire and measuring the phase shift of the signal reflected by the tire. In the preferred embodiment, a waveguide is used to direct the microwave signal toward the tire. A standing wave is created within the waveguide by interference between the transmitted microwave signal and the microwave signal reflected from the tire. A series of crystal detectors mounted along the length of the waveguide measure the standing wave. A processor calculates the phase of the reflection coefficient, and determines the thickness of the rubber layer as a predetermined function of the phase. By proper selection of the microwave frequency and the spacing between the waveguide and the tire, the rubber layer thickness can be uniquely determined as a function of phase for any range of rubber thicknesses likely to be encountered in a tire. In addition, a phase reversal (from 180° to -180°) can be arranged to occur at a specific rubber thickness by proper selection of these parameters. This can be used in the tire retreading process to halt buffing when a predetermined minimum rubber thickness has been reached.
