Abstract: ABSTRACT            A tread belt drive system for heavy mobile equip-ment includes an endless thread belt made up of a plurality of identical links joined together by link connecting pins.  Each of the links has a ground engaging bottom and a top having a cog, or cog portion, positioned medially of the link ends, which cog has fore and aft driving surfaces.  A pair of longi-tudinally extending tumbler rim and roller engaging surfaces which extend above the cog are positioned on the top of the link, one on each side of the cog.  The links have fore and aft pin connections with the pin center below the engaging sur-faces in alignment with the driving surfaces.  The drive sys-tem also includes rollers which support the weight of the equipment and drive and idler tumblers each having a rim and teeth.  The teeth of the driving and idler tumblers are entrap-ped between the fore and aft driving surfaces of the cogs of adjacent links to drive and guide the endless belt; the rollers and the rims of the tumblers bear on and roll along the engag-ing surfaces of the links and the link connection pins follow the tumbler rotation on its pitch circle.  In a preferred em-bodiment, the driving surfaces of the cogs have an involute gear rack profile; and the driving teeth of the tumbler have an involute gear profile.

Abstract: ABSTRACT OF THE DISCLOSURE   A single folded fiberboard carrier for an even number of drinking vessels of varying shapes and sizes, having a central vertical suspending handle portion or section, and a pair of depending hinged aperturedapart panels for clamping the conical or frusto-conical sides of drinking cups when suspended in the carrier, and for preventing tilting or spilling of the contents in the cups when the carrier is at rest and the cups are supported on their bottoms. The vertical handle portion is apertured for grasping with the fingers of one's hand and has depending therefrom tabs for engaging the rims Or the smaller cups to prevent them from falling through their clamping apertures. Hinged divergently downwardly extending from each side of 'he handle portion are panels having elongated cup body engaging apertures, which may have inwardly extending, tabs. At the outer edges of these diverging panels are hingedly supported downwardly and inwardly converging panels with elongated slightly smaller apertures vertically aligned with the apertures in the diverging panels. The bottom edges of the converging channels are hinged and joined together so that the carrier may be collapsed when not being used. One or more of the panels may be provided with an aperture for carrying straws for drinking the liquids in the carried cups.     - 1a -

Abstract: ABSTRACT OF THE DISCLOSURE        A flexible sheet material is disclosed for making air cushion vehicle skirts and the like.  A molded seamless air cushion vehicle skirt and method of making same are also disclosed.  In the method, an uncured, liquid polyurethane is sprayed onto a mold in the shape of a predetermined air cushion vehicle shirt.  This forms a first continuous polyurethane layer on which is laid a foraminous substrate made of triaxially woven Kevlar filament material.  The substrate is then coated with a second continuous layer of liquid, uncured polyurethane.          The polyurethane layers penetrate the substrate and mix together so that when the polyurethane is cured, a continuous molded shirt is formed of material which cannot be delaminated.  Parts of the mold may be masked to produce uncoated areas of the substrate.  These areas may be later sprayed with liquid urethane to produce permeable sections in the air cushion vehicle skirt.  The permeable sections reduce drag when the shirt is mounted on an air cushion vehicle and also prevent undesirable vibration or tramping problems in use.

Abstract: ELECTROMAGNETIC FUEL INJECTOR          -- Abstract of the Disclosure --An electromagnetic fuel injector for use in a spark ignition internal combustion engine and, in parti-cular, for use in a low pressure, throttle body fuel injection system for such an engine.  The fuel injector includes an electromagnet actuated valve having a semi-spherical seating surface thereon for cooperation with an annular valve seat at one end of a nozzle assembly for controlling the injection flow of fuel from the injector and a flat surface for abutment against the end of the armature of an electromagnet.  This valve is biased toward a closed position in seating engagement against the valve seat by a spring associated with the armature and is biased toward an open position relative to the valve seat by an opposed spring upon energization of the electromagnet.  The electromagnet structure includes a small diameter axial extending small diameter guide pin slidably received in a guide bore of the armature for reducing sliding friction of the armature.  In a preferred enbodiment the nozzle assembly is threaded into the injector body to abut against a deformable abutment shoul-der whereby the stroke of the armature-valve can be adjusted.

Abstract: Abstract of the Disclosure A multi-slide holder and editor comprises a rectangular plate-like body having a plurality of rectangular slide-receiving pockets formed between two sets of parallel ribs disposed at right angles to one another.  Upon insertion into its respective pocket each slide enters two spaced parallel open-ended side edge engaging channels, each channel comprising two spaced edge-engaging members.  One of these edge engaging members comprises at least two longitudinally spaced portions with a gap between them, while the other cooperating member is disposed opposite this gap and is of not greater length than the gap, so that the entire body can be formed by a single moulding operation with linearly-moving relatively simple mould parts.  A cabinet for the holder and editor has a source of illumination in the cabinet door, and a plurality of the holders are mounted by channel members on the top and bottom inner wall to move parallel to the door in its open position, so that they can be positioned in front of the door for inspection and editing.  The door can be readily removed to serve as a separate light source for viewing and editing.
