Abstract: ABSTRACT OF THE DISCLOSURE           A turnover apparatus for inverting a first sheet and placing it horizontally upon a second sheet as said sheets are carried along a horizontal path.  The apparatus includes lift-ing arms for raising the leading edge of the first sheet about its trailing edge and lowering arms for receiving the leading edge of the lifted sheet from the lifting arms and lowering the sheet when the same reaches a substantially vertical posi-tion.  The transfer of the sheet from the lifting arms to the lowering arms is responsive to the position of either of the arms when handling relatively wide sheets or to the vertical disposition of said sheet when handling relatively narrow sheets.

Abstract: METHOD AND APPARATUS FOR RUNNING AND RETRIEVING LOGGING INSTRUMENTS IN HIGHLY DEVIATED WELL BORES     Abstract of the Disclosure.  The system consists of means for running a logging instrument and a long semi-rigid extension on a logging cable through open-ended drill pipe.  A head on the upper end of the extension conforms sufficiently close to the inside diameter of the drill pipe that pump pressure down the drill pipe develops thrust across the head to push the extension and logging instrument down the well bore.  A catcher -1a-sub at the lower end of the drill pipe prevents the extension from being pumped out the bottom of the drill pipe.  As the extension and logging instrument are pulled back into the drill pipe by the logging cable, well bore measurements are made and recorded over the interval below the bottom of the drill pipe.          The extension consists of a number of sections that are joined together on top of the instrument as the instrument is lowered into the drill pipe on the logging cable, the extension sections each having a slot along their entire length in order that the extension will fit around the logging cable.  In one embodiment, the extensions are formed of a threaded steel insert connected to a dissimilar metal, for example, aluminum, by a special welding technique in order to enable the entire extension system to be lighter weight and thus supportable by the logging cable.  A cable tension adapter sub at the uppermost top extension causes fluid ports to be rerouted to enable free fluid movement downward through the cable tension adapter sub and restricted movement in the upward direction.  This minimizes swab load when logging out of a well. In addition, this makes it possible to apply fluid pressure down the annulus which will tend to force the cable tension adapter sub up the drill pipe, thus helping to retrieve the logging instrument when stuck.  In the other position of the valving system, there is free fluid movement through the cable tension adapter sub in the upward direction when there is a minimal tension on the cable clamp assembly to allow gravity descent of the instrument and extension system when possible and allows thrust development across the cable tension adapter sub by pumping fluid down the drill pipe.                             -1b-

Abstract: VACUUM INTERRUPTER AND DISCONNECT COMBINATION               Abstract of the Disclosure A compact combination vacuum interrupter and visible break disconnect switch, in which the interrupter is electrically connected in series with the disconnect.          The interrupter is manually closed, and can be tripped manually or automatically on overcurrent or undervoltage line conditions by a quick make, quick break, trip-free operating mechanism.          The disconnect is manually opened or closed by a separate operating mechanism, which is mechanically inter-locked with the interrupter operating mechanism so that the disconnect cannot be opened when the interrupter is closed, or the interrupter cannot be closed when the disconnect is open. The disconnect can be padlocked in its open position.         The interrupter is mounted integral with the movable contact of the disconnect on a pivotable, insulating support member of the disconnect, with the movable contact rod of the interrupter pivotably connected to the interrupter operating mechanism.  When the interrupter is in its open position, the pivotal axis of the interrupter movable contact rod coincides with the pivotal axis of the disconnect insulating support member, so that, when the disconnect is opened, the interrupter is pivoted about the same axis as the disconnect movable contact while the interrupter contacts are maintained at their fully open position.

Abstract: ABSTRACT OF THE DISCLOSURE          This invention relates to a method and apparatus for automatically forming packages of materials or goods such as milk packages from flexible film and to the novel packages pro-duced thereby.  The roll stock film is passed over a forming shoulder to give it a tubular shape and the opposite edges are joined by a sealing bar to form a tubular portion.  The milk pouches or other material to be packaged are then dropped into the tubular portion which has previously been laterally sealed across the bottom.  The weight of the pouches draws the film down between a pair of reciprocating cutting and sealing jaws when they are opened until the pouches come to rest upon a pivotal support member.  The jaws are then closed to form two lateral seals, i.e. one for that package and one for the next package, and a lateral cut separates the packages.  The package thus formed may also have an upper handle portion.
