Abstract: ABSTRACT OF THE DISCLOSURE    A refrigerator cabinet having a metal outer shell and a plastic inner liner, containing a partition between fresh food and freezer compartments formed of a metal plate defining the fresh food compartment ceiling, a rigid expanded styrene bead thermally insulating divider mounted on the plate, and a plastic tray forming the freezing compartment floor mounted on the divider.  An elongated strip of flexible polyurethane is folded length-wise over a vertical edge of the plate so as to form a compressible, resilient air tight thermal seal between the sides and back of the plate and the adjacent liner walls regardless of changes in the gap distance between the plate and liner caused by the thermal variations of refrigerator operation or reasonable manufacturing variations.  The partition inserts into channels formed on the sides of the liner which are partially defined by upper ledges with overlap raised flat rims extending along the sides of the tray to prevent unsightly gaps from occurring between the tray and the liner as a result projecting tabs formed on the sides of the rims at the front of the tray project behind frontal edges of the outer shell a distance sufficient to prevent unsightly gaps between the sides of the tray and the edges of the shell resulting from thermal variations or manufacturing variations.

Abstract: ABSTRACT OF THE DISCLOSURE     A control device for a continuous processing line which is fed material from a coil utilizes information regarding the outside diameter of the material on a coil having a constant inside diameter as a basis for its control functions. A typical application is in the control of a strip accumulator (15) in n strip processing line wherein strip (8) on a revolvable coil is drawn from an uncoiler (10) by the revolvable pinch rolls (16) of the accumulator at which point a certain quantity of material is stored so that when the end of a   coil is reached a new coil may be attached to the old coil without stopping the line.  In such instances it id highly desirable that the accumulator be substantially filled so that a maximum time is available to attach the new coil. The control device includes means (31) providing a signal proportional to the revolutions of the pinch rolls and means (30) providing a signal proportional to the revolu-tions of the supply coil. The pinch roll revolutions are counted by a counter (38) and if the counter receives the signal proportional to the revolution of the supply coil after counting a predetermined number of pinch roll revolu-tions, it is reset to count again until such time that the counter does not reach the predetermined number of counts before receiving a supply coil revolution signal at which time accumlator control is initiated.

Abstract: ABSTRACT:            "Apparatus for converting cinematographic pictures into video signals".           An apparatus is described for converting cine-matographic images into video signals. The film gate in which a frame to be scanned is located is illuminated uniformly. The film is scanned by means of a rotatable scanning mirror, which with the aid of an imaging system images one line of the film frame onto one row (three rows for colour film) of radiation sensitive detectors. The detectors of a row are read sequentially. The illu-mination beam has a large aperture angle in a first plane transverse to the direction of film transport and a small aperture angle in a plane transverse to the first plane. The film movement is detected with the aid of a sprocket hole detection system, in which an elongate narrow light spot, whose longitudinal direction is trans-verse to the direction of film transport, is projected onto the strip of film with the sprocket holes. The posi-tion of the scanning mirror is detected with the aid of two gratings of special shape.

Abstract: 48,390 ABSTRACT OF THE DISCLOSURE         This invention provides shielded access to the irradiated heat exchanger tube bundle of a nuclear steam generator contained within a cask after removal from the generator.  This tube bundle must be reduced in size and confined for removal from the containment building through hatchways of generally limited size.  Access to the en-closed bundle is at the flanged joints of adjacent sec-tions forming the cask and which are vertically separated to  permit  an oxygen  lance  to be  inserted  therein  for burning the tubes at that level.  A rotatably supported annular  seal  ring  covers  the  separation  and  shields against  the  escape  of radiation or irradiated material during  the  burning process.   The  ring provides  access ports through which roller supports are mounted on the cask and provide access of the cutting tool to the tubes. Rotation of the ring on the rollers permits the tool to be inserted  completely  around  the  cask.   After  the  tubes within one section of the cask are severed, the tubes and that portion of the cask are removed and the ring raised to a next position where the procedure is repeated.

Abstract: AUXILIARY HYDROSTATIC DRIVE SYSTEM                   Abstract of the Disclosure The steerable wheels of a hydraulically driven vehicle are provided with fixed displacement type auxiliary motors which are connected in parallel both with each other and with the motor which powers the main drive wheels.  A selector valve permits the motors for the steerable wheels to be optionally connected and disconnected from the reversible, variable dis-placement main pump.  Flow dividers in the hydraulic lines limit the maximum flow of fluid to any one auxiliary drive motor.  To prevent large power losses when the steerable wheel assist mode is not being utilized, the selector valves are placed in close proximity to each fixed displacement motor.  This al-lows the motors to circulate large quantities of fluid around a closed loop at minimum pressure drop.

Abstract: PLASTIC CONTAINER WITH INTERNAL RIB RE-INFORCED BOTTOM AND METHOD OF FORMING SAME                     ABSTRACT OF THE DISCLOSURE         This disclosure relates to an unexpected increase in the strength of a bottle bottom of the champagne type by the addition of ribs internally of the preform when the pre-form is axially stretched prior to the blowing thereof within the blow mold.  Most particularly, by adding internal ribs to the interior surface of the bottom defining portion of the preform, the preform has the bottom forming portion unduly strengthened against shrinkage in wall thickness when the preform is axially lengthened through the use of a stretch rod.  The net result is that the stretching of the preform and the thinning of the wall is held to a minimum in the bottom forming portion of the preform and is transferred primarily to the body forming portion of the preform where lesser wail thickness does not unduly detract from the strength of the bottle.
