Abstract: EASY OPEN BEVERAGE CAN - NON-DETACH    ABSTRACT OF THE DISCLOSURE          An easy opening beverage can wherein the closure is of the push-in type.  The dispensing opening in the container is defined by a sealing ring into which there is engaged a peripheral flange of the closure member with the closure member being held initially with respect to the sealing ring only by a mechanical interlock.  Pressure within the can tightly forces the closure member into sealing engagement with the sealing ring and normally prevents removal.  A lever is connected to the sealing ring to effect distortion thereof and bleeding-off of pressure from within the can so as to relieve the holding pressure on the closure member, after which the closure member may be readily pushed into the can in an opening action.

Abstract: ABSTRACT OF THE DISCLOSURE           A fluidized bed separator is disclosed, for use in dry processing of a mixture of solid particles of different specific weight.  The suspension bed of the separator is associated with an air deck operating with a single-particle-layer and adapted to receive heavy particle fraction discharged from the suspension bed and still containing a small portion of light particles.  The air deck operates such that a pure heavy particle fraction travels in a direction opposite to that of light particle fraction, the latter being recirculated to the suspension table as it still contains a small portion of tiny heavy particles.  Since the air deck is preferably secured to the suspension table, the reciprocating drive of the table also drives the deck, the level of the deck relative to the suspension table is selectively adjustable.  The device is extremely simple compared with prior art and is more universal as its operation is virtually independent on the shape of particles of the respective fractions.  It is particularly suitable in processing mixtures having relatively small volume of heavy particles, wherein a pure heavy particle fraction is to be obtained.

Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed herein is a lawn mower including a rotatable cutter blade, a reciprocating internal combustion engine drivingly connected to the cutter blade and a venting arrangement for venting the engine cylinder combustion chamber at engine shut down to decrease the engine coast-down time. The venting arrangement includes a flow passage having an inlet port which opens into the combustion chamber and a discharge port which either opens directly to the atmosphere, is connected in communication with the engine crankcase, or is connected in communication with the engine exhaust system. Venting of the combustion chamber through the flow passage is selectively controlled by a valve which is operably connected to the ignition switch and is opened in response to movement of the ignition switch from an engine operating position to an engine shutoff position.  The valve remains open during engine coast down and the minimum cross sectional flow area of the flow passage is sized relative to the volumetric displacement of the piston so as to produce pumping losses which minimize the time required for the engine to come to a complete stop.

Abstract: ABSTRACT OF THE DISCLOSURE     This invention is concerned with concrete sandwiched walls which are filled by placing an insulating board between the forms for concrete prior to pouring the concrete.  The problem to which this invention is addressed is that of providing a simple, inexpensive device which can be utilized in a manner compatible with traditional building methods, for maintaining the insulating board in position during the pouring of the concrete.  This is accomplished by an insulating board retaining member centrally secured to a conventional form tie.  The retaining member has a central section, a leading section and a trailing section.  These are initially substantially flat so that the retaining member can be forced into the form tie to which it is secured, through the insulating board.  The leading and trailing sections  are then bent to form a U to retain the insulating board.  This invention comprises also a building form structure and a building method each utilizing a device in accordance with this invention.

Abstract: ABSTRACT         This invention provides an articulating beam and belt system for an endless track vehicle drive.  This track drive, in single or multiple configurations, is attached only by resilient means to the vehiclebody, allowing the beam and belt system to track freely.  The belt used can flex universally, preferably with resilient resistance to flexing.  It is supported by wheels attached to a jointed beam that articulates at each joint.          Initiation of track curvature is accomplished by forced rotation of the end beam links.  Beam articulation with full belt flexing is so designed to allow the beam support wheels to roll the beam into a curved configuration, thereby changing vehicle direction with a minimum of sliding friction between ground and track.

Abstract: ABSTRACT OF THE DISCLOSURE     A packageable system employs principles of Doppler holography on near-field objects to produce images from which photographs, transparencies or video reproductions can be made with simultaneous improvements in depth of field, foreground-backregion exposure ratio, and resolution (where degraded by the object medium ). The apparatus includes a laser and associated optics for illuminating an object on A rotating/oscillating platform from which reflected light is collected and imaged on or near a hologram plane along with a Doppler-shifted reference beam:   a beam splitter splits a laser beam into two parts. For one beam an expander provides a diverging beam which reflects through a mirror or beam/splitter onto the object.  Reflected light passes from the object through an aperture in an object lens where it is focused and projected to a new focus on or near the hologram plane.  Another part of the beam split off by the first beam splitter is directed to A mirror, through a beam expander and a collimator, to strike a rotating oscillating reference mirror.  A pair of reference beam focus lenses conjugates the plane of the reference morror onto or near the hologram plane.  With proper adjustments of ? and ? (instantaneous reference mirror angular velocity and focus position of the object lens), Doppler-resolved holographic images appear at the holographic plane.
