Abstract: A tensioner assembly pre-stretches a film web prior to unitizing a pallet load. The film web undergoes three stages of stretching by the tensioner assembly which includes two driven rollers and a resiliently biased dancer roller. The dancer roller engages the film and maintains it under continuous tension loading as the pallet load rotates. An electrical control signal proportional to the angular position of the dancer roller is employed by a control circuit to vary the rotational speed of the pretensioner drive rollers. The film web is stretched in a first stage between a feedstock roll and the first drive roller. A second stage of stretching occurs between the first driven roller and the second driven roller. Finally, the film web undergoes a third stage of stretching between the second driven roller and the pallet load, with the web being maintained under tension at all times by the resiliently biased dancer roller.

Abstract: A method for packaging and shaping sanitary napkins (10) in a container (44) is described. The method comprises advancing a succession of pre-moistened, embossed sanitary napkins (10) along a predetermined path (30), deflecting the ends of the napkins (10) by means of deflector guides (32) to impart a non-planar shape to the napkins (10), introducing the napkins (10) into a container (44) which provides packaging therefor, and reducing the moisture content in the napkins (10). After the moisture content is sufficiently reduced, e.g., as by evaporation during commercial storage or shipment, the napkins (10) retain their non-planar, curved shape after removal from the container (44) for individual use.

Abstract: The disclosure concerns an integral weigh wrapper for wrapping products in stretch film, by weighing each product as it is placed on an infeed support surface, and feeding successive weight signals to a data processor. Successive signals are compared, and when a stabilized weight signal is received, as determined by the successive comparisons, the data processor produces a start signal which activates a drive motor to rotate one revolution. This initiates one cycle of operation of the weigh wrapper, in which the product is advanced from the infeed station to the wrapping station, a wrapping cycle is initiated for any product then in the wrapping station, and a previously wrapped product is advanced to a printing and labeling station--where it is automatically indexed, a printed label pneumatically applied to a selected location on the wrapper, and the wrapped and labeled product outputted.

Abstract: A ground speed control for an agricultural combine driven by a turbocharged engine through a variable transmission continuously monitors a plurality of speed and load parameters of the combine and engine, identifies the controlling parameter representing the limiting capacity in the harvesting process as field conditions change, and varies combine ground speed in response to such controlling parameter to maximize the harvest cutting rate. Sensors monitor ground speed, boost pressure and engine speed parameters and convert them to electrical signals which are compared to boost pressure and ground speed setpoint signals selected by the operator and to a fixed engine speed setpoint signal to derive error signals for such parameters. Voltage level sensitive OR-means and AND-means establish deadbands for the error signals having upper and lower limits on opposite sides of the corresponding setpoint signals.

Abstract: A catalytic converter is adapted to retard spark timing to increase the temperature of the converter catalyst when a temperature sensor within the converter senses low exhaust temperature. A vacuum advance mechanism is responsive to intake manifold vacuum conducted thereto via an intake vacuum passageway to advance spark timing for the engine. The temperature of exhaust gas from a catalytic converter for exhaust emissions is sensed. When the sensed temperature of the exhaust is below a predetermined value, a comparator outputs an actuation signal which is used to cause a solenoid valve to open an air passageway to admit atmospheric air into the vacuum advance mechanism so that spark timing will be retarded, thereby increasing the temperature of the catalyst.

Abstract: This patent refers to a gas-liquid separation process by centrifugal force, which takes place in a fast turning vortex confined in a tube, similar to inventor's former patents. Against the separating centrifugal force the thermal (Ranque) effect tends to heat the periphery of the tube and vaporize the liquid. This improvement refers to a method of preventing the vaporization of the liquid, either by cooling a short section of the periphery with a cooling jacket, or by taking out the liquid at a short distance from the inlet, where the heating effect on the periphery is minimal, and insulating the liquid from this heating effect. It also refers to the method of control of this liquid separation, and the process of using it as a wellhead oil and gas separator.

Abstract: A Stirling heat pump driven by a Stirling engine has its stroke limited under conditions of decreasing pump load. This stroke limitation is accomplished by effecting the flow of gas from the engine to the heat pump in response to a maximum piston stroke. Preferably, a valved passageway is formed in communication between the gas in the engine and the gas of the pump. The passageway is valved by a means which normally blocks the flow of gas but opens when the piston of either the pump or the engines strokes to an extreme selected position. The passageway opens into the engine and into the pump at zones so that when the valve is open the zones are at a pressure differential which will cause a flow of gas from the engine to the pump. By this means the power delivered by the heat engine portion of the machine can be made to be equal to the power absorbed by the heat pump at all conditions of heat pump temperature differential.

Abstract: An improvement in an absorption heat pump cycle is obtained by adding adiabatic absorption and desorption steps to the absorber and desorber of the system.

The improved system can operate with a larger difference between high and low working fluid concentrations, less circulation losses, and more efficient heat exchange than a conventional system.
