Abstract: Apparatus and method for the automatic packaging of one or more articles. An adjustable web guide structure that guides the webs of film into a configuration that mimics the geometry of a package to be wrapped is provided. The webs are conveyed over the guide structure, which structure provides an appropriate predetermined shape defining a web envelope for proper package entry and flow through the wrapping system. The position and geometry of the guides causes the web envelope to form around the corners of the product to be package to minimize film requirement, and allows for fluid transition from web supply rolls to package shape. External tension rods can be used to assist in preventing or minimizing web wrinkling. Guide rolls can be used in conjunction with the guide structure to assist in guiding and tracking the web material, as well as to provide axial transverse tension for proper web forming.

Abstract: A method of packaging point-of-purchase items involves supplying plastic bags as a continuously attached length of bags, each bag being separated from adjacent bags along the supply length by a perforated tear line. The length of bags is stored on a storage form or in another suitable manner permitting advancement of bags when pulled out of the stored condition. The perforated tear line cuts entirely through the web of bags. However, the perforation along one side of each bag is broken to present an open flap through which contents can be added to the bag prior to removal from the web. The method of using the bags for packaging produce, groceries or other articles generally selected at point of sale and which are generally segregated by type for later pricing by weight or unit, permits a user to at least partially fill a bag prior to removal from the web.

Abstract: In the control system for a turbo-charged diesel aircraft engine, a target value for a fuel injection amount is determined by the stroke of a throttle lever. A boost compensator determines the maximum limit for the fuel injection amount in accordance with the boost pressure of the engine in order to suppress the formation of exhaust smoke.

An electronic control unit (ECU) calculates an increase rate of the stroke of the throttle lever based on an output of the stroke sensor disposed near the throttle lever. The ECU determines that the current operating condition of the aircraft requires a rapid increase in the engine output power when the increase rate of the stroke is larger than a predetermined value and increases the maximum limit determined by the boost compensator.

Abstract: A central control system controls peak power of multiple air conditioners that includes indoor units installed in rooms of a building and an outdoor unit for controlling refrigerant circulation. A central controller is connected to the multiple air conditioners via a network to perform central control or monitoring of operations of the air conditioners.

A signal converter is connected between the multiple air conditioners and the central controller to perform mutual conversion of different protocol signals communicated between the multiple air conditioners and the central controller. This decreases excessive electricity costs due to excessive power consumption while approximately maintaining cooling/heating efficiencies, and also prevents the entire power of the building from being cut off.

Abstract: In a vapor-compression refrigerant cycle system, a switching device is provided to switch one of a first mode where high-pressure refrigerant discharged from a compressor is directly introduced to an exterior heat exchanger and a second mode where the high-pressure refrigerant is directly introduced to an interior heat exchanger. When the second mode is set, the pressure of the high-pressure refrigerant is set higher than a predetermined pressure by a constant-pressure control valve. Accordingly, it can prevent heating capacity of the interior heat exchanger from being greatly changed even when thermal load of the vapor-compression refrigerant cycle system is changed, and heating capacity of the interior heat exchanger can be improved in the second mode.

Abstract: A transcritical refrigeration system includes a compressor, a gas cooler, an expansion device, and an evaporator. Refrigerant is circulated though the closed circuit system. Preferably, carbon dioxide is used as the refrigerant. A fan moves outdoor air that exchanges heat with the refrigerant across the evaporator. The speed of the fan is regulated to regulate the evaporator pressure and to adapt the evaporator to different environmental conditions to achieve the optimal coefficient of performance. During high ambient conditions, the fan speed is decreased, decreasing the refrigerant mass flowrate in the system. The energy exchange per unit mass of the refrigerant in the gas cooler increases and the work of the fan decreases, increasing the coefficient of performance of the system. During low ambient conditions, the mass flowrate of the system is low and there is more heat transfer thermal resistance on the refrigerant side at the evaporator. The speed of the fan is lowered to decrease the work of the fan.
