Abstract: PROGRAMMABLE RANDOM SIZE CASE SEALING MACHINE            Abstract of the Disclosure A machine for sealing the top and/or bottom flaps of random size cases is disclosed. The location of the front and rear of cases moved through the machine by a conveyor is continuously monitored by a programmable controller that uses the location information to control the operation of various case alignment, flap folding, and glue-applying mechanisms. Case entry is initially prohibited by a raised gate. When the conveyor reaches a predetermined position the gate is lowered and a case enters the machine. As a case enters the machine, the case is aligned along the center of the case path of travel throughthe machine; and, a T-deck drops to allow the bottom major flaps to separate from the bottom minor flaps. Such separation is necessary for the bottom flaps to be sealed simultaneously with the top naps. If the bottom flaps are sealed when the case enters the machine, no separation occurs. As the case continues to move through the machine, a kicker carriage is lowered, top rails (mounted onthe kicker carriage) are moved inwardly and a kicker (also mounted on the kickercarriage) is actuated. As a result, the upper minor flaps of the case are first folded, followed by a partial folding of the upper major flaps. The case is thenmoved past top and bottom glue heads that apply glue (if programmed to do so) to the top and bottom flaps at front and rear locations in an operator programmed (continuous or intermittent) pattern. The length of the glue pattern is also operator programmable. After the glue is applied, the case moves under acompression carriage that is lowered to apply vertical pressure that causes the major flaps to adhere to the minor flaps in regions where glue is applied by theglue heads. As the case moves beneath the compression carriage discharge rails are moved inwardly to maintain the case alignment. After each of their functions has been performed, the various movable mechanisms (the infeed, top and discharge rails, and the kicker and compression carriages) are repositioned for the next case being moved through the machine. In this regard, two cases may be sequentially moved through the machine by the conveyor mechanism, with the front and rear of both cases being continuously monitored by the programmable controller.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention includes a plurality of input/output pro-cessors communicating with a master processor. Each of the input/output processors has a filtering mechanism to filter the inputs before transmission tothe master over the communication channel precluding the necessity of filtering at the master. More importantly, the shared communications system is not loaded down with every change of an input. Because of this feature, only meaningful changes are put on the communication line, thus substantially reducing its load which makes its effective response time stay high. The inputs when received at the master can be immediately handled to improve the central processor response time. Two types of filtering are provided, in particular, transition and debounce filtering to respond to switch and sensor inputs. Also, there is provided a means to programmably select the type of filter and the time period of filtering.

Abstract: ABSTRACT OF THE DISCLOSURE Apparatus for the production of plastic film by the extrusion of a tube thereof includes a first air ring disposed at the die exit and delivering an annular stream of cooling air to the surface of the emerging tube, which is in a stable expansion phase as it escapes the die internal pressure.          Preferably the stream is directed axially of the tube path.  The apparatus includes the combination of a sizing cage and a second air ring that is mounted for longitudinal movement along the tube.  The tube is established with the air rings close together and they are moved as soon as possible as far apart as possible,  The second air ring is located just below where the tube begins to expand and delivers an annular stream of air, preferably in a known manner away from the tube to form a vacuum which stabilizes the tube.  The cooling air stream from the second ring can be high since the tube is again in a stable expansion phase with the material at an appropriate temperture.        The attached sizing cage supports the tube and holds it concentric with the second air ring against turbulence and the possibility of oscillation.  An additional mechanical or air tube stabilizer may be provided at the inlet to the second air ring consisting of a ring of rollers of low friction coefficient material.

Abstract: Abstract An electrical heating apparatus such as an electric blanket includes a resistance heating wire embedded in the blanket together with a single heat sensitive conductor also embedded in the blanket and disposed in a thermally responsive relation to the heating wire.  The heat sensitive conductor has a positive temper-ature coefficient electrical impedance which is continuous along its entire length.  As an overheating condition arises in the blanket this is sensed by the heat sensitive conductor which is being monitored by a controller to reduce or cut off current to the resistance heating wire as necessary.  The invention makes it a practical proposition to monitor all heated portions of the blanket with the elimination of all discrete temperature sensing elements.

Abstract: ADJUSTABLE AIR INLET CONTROL SYSTEM                  Abstract A rectangular air inlet control plate is pivotably mounted in the air intake passage of a forced air furnace to control the air intake volume and, thereby, insure optimal combustion of the fuel in the furnace.  The plate is adjustably counter-balanced to a closed position and is is further adjusted to allow the optimum volume of air intake during operation of the forced air furnace.  The rectangular shape of the plate provides for fast opening and closing of the air intake during startup and shutdown transients, since the actuation angle of the plate is reduced in proportion to its length.  The plate is mounted in a funnel-shaped air intake structure to reduce the noise and allow a maximum volume of air to enter the intake.  A windscreen is mounted on the funnel-shaped air intake in order to act as a turbulence breaker for the incoming air, and also to prevent ingestion of large debris into the air intake.

Abstract: TITLE Extraction of Substances From Aqueous Solution Abstract of the Disclosure Extraction of dissolved substances from aqueous solution by contacting the solution with a mixture of fluorocarbon solvents comprising normally gaseous monochlorodifluoromethane and normally liquid trichlorotrifluoroethane.  Contact is carried out under pressure which maintains the solvent mixture in the liquid state.  The aqueous solution and the solvent mixture form two phases upon standing. Separation of the phases and release of pressure on the fluorocarbon solvent liberates the monochloro-difluoromethane from the mixture, and extracted material insoluble in trichlorotrifluoroethane either precipitates or forms a second liquid layer.  The insoluble material is then separated from the trichloro-trifluoromethane.
