Abstract: VAN TENT FOR OPEN-ENDED VANS               ABSTRACT OF THE DISCLOSURE               This invention relates to a tent-like foldable room-forming extension for rear-opening van-type vehicles charac-terized by hanger brackets mountable on the upper rear outside corners of the van; a foldable subframe having its adjacent front corners fitted with eyelets detachably connectable to the hanger brackets to define a roof-supporting structure, foldable subframes depending from the side margins of the roof-supporting subframe and cooperating therewith to define an arch, a foldable fabric skin covering, the top and sides of said frame as well as the opening at the rear with an openable curtain wall, a forwardly-extending sealable cuff at the front end adapted to be drawn snug against the rear end of the van, and an expandable panel stretched between the sidewalls along the underside of the van cooperating therewith to enclose the front.  This cuff allows the tent to be connected to vans having rear ends of different heights, widths and configurations.  The sideframe members of the tent rest upon the ground when the tent is used on panel vans and cooperate therewith to produce a free-standing assembly.  With step-in vans, on the other hand, the sidewalls hang free from the roof and channel brackets are used on the van body near the bottom to maintain a fixed spacing therebetween.

Abstract: ABSTRACT OF THE DISCLOSURE     A nestible merchandise cart including a rear frame and hinged side frames which pivot outwardly until limit stops are engaged, and a movable shelf which, when in place to support a load, locks the side frames into positions generally perpendicular to the rear frame.  The shelf can be raised and stored, which releases the side frames to pivot outwardly and form a tapered nest into which a like cart will fit nestingly.  The side frames may be biased outwardly by springs and pivot outwardly automatically when the shelf is raised, and may also pivot inwardly against the rear frame to a collapsed position suitable for high density packing and shipment of the cart.

Abstract: ABSTRACT OF THE INVENTION       A one-piece bed pillow consisting of a pillow shaped molded body of open cell urethane foam material having its outer surface formed with a regular pattern of interconnected grooves. The pillow is formed in a mold which is placed in an upright position during foaming of the pillow body so that in use the pillow has a plurality of internal cells which are generally perpendicular to the direction in which load is applied to the pillow to thereby impart desirable load-deflection characteristics to the pillow so that it has low resistance to Initial load and has increased resistance to higher loads. The user of the pillow thus finds that it has a desirable initial softness with a subsequent firmness that gives the user confidence in the ability Or the pillow to hold the user's head.

Abstract: ABSTRACT OF THE DISCLOSURE         An illuminating and scanning system is disclosed for translucent or X-ray film which circumvents the need for a wide angle, large entrance pupil lens as used in the convention-al oscillating mirror scanning system.  The system is divided into two distinct and separate systems including an illuminating and n scanning optical system having an oscillating mirror which includes in its assembly a single element meniscus lens serving as an objective or first lens in the system.  Coupled to the oscillating mirror assembly is a slotted aperture plate located at the image focal point which establishes the "X" dimension of the scanned element ares upon the film.  The aperture plate is moved in parallel along the scanning optical axis to follow the focal point as the distance from the objective lens to the scanned element area varies during the sweep of a scanned line.  The illuminating optical system for establishing the "Y" dimension of the scanned  element area upon the film includes a light source and first and second cylindrical lenses having an illuminating aperture plate disposed therebetween.  Through the illuminating optical system diffraction and stray light are substantially eliminated, while little or no spectral radiation passes from the scanned image to the detector cell in the scanning optical system.

Abstract: A B S T R A C T           A method and apparatus for packaging thermoplastic fluid material is the subject of the present invention.  The thermoplastic material is mixed at an elevated temperature and emptied in predetermined batch quantities into a holding area.  A gate in the bottom of the holding area is operable to empty the batch of material in a very short time span.  A plurality of heating elements are disposed beneath the outlet of the holding means and are maintained at A temperature high enough to cause parting of the fluid material as it passes over the heating elements.  Thus the batch of material from the holding area will be divided into a plurality of indi-vidual masses as the material passes over the heating elements. By utilizing a number of heating elements equal to one less than the number of containers to be filled, and by spacing the heating elements equi-distances apart, the individual masses of material will be equal in size and the number of individual masses will equal the number of containers.  The containers are positioned immediately beneath the heating elements to receive the material and are filled simultaneously.

Abstract: SKIN MELTING                 ABSTRACT OF THE DISCLOSURE     A surface treatment for a class of metallic articles is described.  The treatment involves the melting of a thin surface layer of the article by a concentrated energy source, within a narrow set of parameters  The melting step is performed in a manner which maximizes the temperature gradient between the melted and unmelted portion of the article, consequently, cooling and solidification upon the removal of the energy source is extremely rapid occurring at rates in excess of 103°F/sec.          The preferred energy source is a continuous wave laser and in the preferred embodiment, a flowing inert gas cover is used to minimize melt contamination and plasma forma-tion.  The technique may be used to produce amorphous surface layers in a specific class of eutectic alloys.    In another class of alloys, based on the transition metals and containing precipitates rich in one or more metalloids, uniquely fine microstructures may be produced.
