Abstract: A system for performing radar cross section measurements of a target may include a radar system and an antenna associated with the radar system to transmit signals and to receive reflected signals from the target and a clutter source. An EM tagging device is locatable proximate to the clutter source to spectrally tag the clutter source by causing changes in an electromagnetic signal reflected by the clutter source when a predetermined radar signal transmitted by the radar system is incident on the target, the clutter source and the EM tagging device. A module may identify a spectrally tagged component of reflected signals received by the radar system from the target, the clutter source and the EM tagging device.

Abstract: A novelty kit for provide supplies and to amuse a caregiver expecting a baby includes a container including a bottom wall and a perimeter wall being attached to and extending upwardly from the bottom wall. The perimeter wall has an upper edge defining an opening extending into an interior space of the container. Humorous indicia are positioned on an outer surface of said container. A cover is attached to the upper edge of the container. The cover is selectively positionable in a closed position extending over said opening.

Abstract: A method for forming an optical fiber includes drawing the optical fiber from a glass supply and treating the fiber by maintaining the optical fiber within a treatment temperature range for a treatment time. Preferably also, the fiber is cooled at a specified cooling rate. The optical fiber treatment reduces the tendency of the optical fiber to increase in attenuation due to Rayleigh scattering, and/or over time following formation of the optical fiber due to heat aging. Apparatus are also provided.

Abstract: A method for forming a doped optical fiber includes drawing the optical fiber from a doped glass supply at a draw speed and a draw tension sufficient to introduce a heat aging defect in the optical fiber. The optical fiber is treated by maintaining the optical fiber within a treatment temperature range for a treatment time while preferably maintaining the optical fiber within a treatment tension range to reduce the tendency of the optical fiber to increase in attenuation over time following formation of the optical fiber. Apparatus are also provided.

Abstract: An apparatus for forming optical fiber from a glass preform using a forming gas includes a draw furnace having first and second opposed ends. The draw furnace defines an exit opening at the second end and a furnace passage extending between the first and second ends. A control tube extends through the exit opening of the draw furnace. The control tube defines first and second opposed tube openings and a tube passage extending between the first and second tube openings. The control tube includes a first tube section and a second tube section. The first tube opening and the first tube section are disposed in the furnace passage and cooperate with the passage of the draw furnace to form a buffer cavity adjacent the control tube. The second tube opening and the second tube section are disposed downstream of the draw furnace. The tube passage includes an inner diameter. The inner diameter of the tube passage is less than an inner diameter of the furnace passage.

Abstract: The present invention relates to an apparatus, automated system and method for packaging food products. The system has a novel arrangement for transferring the product from a receiving station to a bagging station which arrangement includes mechanical devices for pulling a bag over the product. The system further includes a unique platen system for transporting the bagged product to various stations where it is vacuumized, sealed, trimmed, and finished. Optionally, the system includes a plurality of needles for injecting a fluid such as a basting fluid into the product.

Abstract: A method of opening a bag includes the steps of providing a bag having a first lip and a second lip defining a substantially flat bag opening, the first lip being secured to adhesive strips for positioning the bag and the second lip having an extending portion extending beyond the first lip; and applying a force to the extending portion of the second lip of the bag so as to displace the second lip away from the first lip, thereby opening the bag opening.

Abstract: A method of cleaning and polishing a variety of porous and non-porous materials including porcelains, plastics, marble, glass, and finished wood. The polishing compound is comprised of an abrasive powder, an hydroflouric acid, and an organic solvent. The polishing compound is applied with a cloth and scouring of the surface to be cleaned and polished is accomplished with a soft cloth or with a polishing machine. The invention effectively removes scratches, stains, and blemishes from the surface to be polished and after scouring the result is a blemish free and polished surface.

Abstract: This application relates to a piston having two sets of three roller bearings mounted by means of milled grooves in a lightweight skirt of less diameter than the piston head. Each triangularly arranged set of roller bearings is symmetrically arranged to give a rolling three point stability and rolling anti-friction support to the piston as it reciprocates in the cylinder. Lubrication of the roller bearings is enhanced by openings through the piston skirt in the area of the oil rings above the roller bearings. The roller bearing axles are mounted in milled grooves.
