Abstract: ABSTRACT OF THE DISCLOSURE         A flying spot scanning system is provided by utilizing reflected light from a multifaceted rotating polygon which is then directed to the scanned medium. A light source illuminates a portion of the mirrored sides of the polygon during each scanning cycle, to provide a desired sequence of spot scanning.  In each scanning cycle, information is transmitted to the scanned medium by modu-lating the light from the light source in accordance with a video signal.  An optical convolution of elements including at least two lenses having power in one optical plane and substantially no power in the other plane, is provided in combination with the polygon.  One of these lenses is placed in the optical path between the polygon and the scanned medium with its power plane substantially parallel to the axis of rotation of the polygon for allowing a wide variance in runout tolerance of the scanning system. The other lens is placed in the optical path between the light source and the polygon with its power plane substantially perpendicular to the axis of rotation of the polygon.

Abstract: Abstract of Disclosure A building construction and method for transforming a large open space into a plurality of smaller rooms.  A portable room module is folded into an essentially planar configuration for storage.  The module is supported upon retractable wheels and accommodates movement from a storage location to a predetermined utility location within a larger room.  In the utility location, the portable room module is expanded to room size and an elevated ceiling unit is lowered so as to rest upon the room module and form a ceiling unit therefor.  Partially collapsible insulating material is situated at joints of the wall portions of the room module and also at the top and bottom of the wall portions so as to form an acoustic and hermetic seal when the module is unfolded and when the elevated ceiling unit comes to rest upon the wall panels.  The weight of the ceiling unit simultaneously (a) displaces the wall panel vertically downward over the retractable wheels to secure the position of the wall panels and (b) compresses the insulating material at both the top and bottom of the wall panel.

Abstract: Abstract of the Disclosure Disclosed is a process chromatograph including a column for separating fluid samples into their individual components, and a density-responsive detector connected to the column output to produce a pressure signal representing the concentration of the separated components.  The column and associated elements are contained within a thermally-insulated housing the interior spaces of which are heated and maintained at a set-point temperature by a temperature regulating system.  Heat energy is sup-plied by steam to one section of a two-section tubular heat-exchanger.  A stream of air is caused to flow through the other section and into the housing interior, to transfer heat thereto.  The rate of heat transfer is automatically controlled by a thermostatic control which continuosly adjusts the flow of air through the heat exchanger so as to maintain the interior temperature at a desired set-point.

Abstract: FORAGE HARVESTER HAVING COMBINED   CUT-AND-THROW CYLINDER                ABSTRACT OF THE DISCLOSURE         The cutting cylinder has knife segments extending across its periphery in a staggered pattern so that each row winds essentially helically from end-to-end of the cylinder, thereby providing an effective shearing action as the knife segments cooperate with a stationary shear bar to sever incom-ing crops into countless short lengths.  Air and crop cups lo-cated directly below the knife segments capture the short lengths before they can enter the interior of the cylinder and sweep the same through the cutting chamber, blasting them out the discharge spout without the assistance of an auxiliary fan. By keeping the elongated cups substantially parallel to the axis of rotation of the cylinder and perpendicular to the path of travel of the entering crops, regardless of whether the cut-ting edges of the knife segments are arranged parallel to or slightly oblique to the axis of the cylinder, the full thrust of the spinning cylinder is utilized to propel the crop pieces up the spout for maximum efficiency.  The airflow path within the cutting chamber is also designed to provide the most effi-cient use of operating power possible.

Abstract: Abstract A pneumatic brake system employing dual-diaphragm, spring-actuated, air-released brake actuators is provided with an inversion valve which, in the event of a brake system failure, prevents the brakes from being automatically applied while permitting controlled brake application by releasing compressed air from each actuator's spring chamber in an in-verse ratio to that normally supplied from the system by the operator applied brake valve thus permitting a controlled spring brake application. The valve employs first and second pressure responsive pistons with associated valve seats to maintain the actuator springs compressed with air at supply pressure when the vehicle is normally operated. The air at supply pressure in each actuator's spring chamber is automati-cally ported to a lower pressure through the valve when a system failure occurs and prior to brake application to insure fast response time of the spring actuated brake.

Abstract: ABSTRACT OF THE DISCLOSURE     A berry picking device consisting of a container having an open front with a scoop-like portion projecting forwardly therefrom.          The scoop-like portion has a bottom wall formed at least in part by a plurality of spaced-apart tines for stripping berries from branches of shrubs, trees or the like carrying the same.  The berries stripped from their branches pass over the tines through a screen into a berry collecting compartment.

A portion of the for-wardly projecting tines pass over another compartment and the spacing between the tines is such that small berries pass therethrough into the compartment thus separating the collected berries into two different sizes.
