Abstract: A method and apparatus for making bags or pouches is disclosed. It includes a track, at least two sleds that move on the track, and operating stations mounted on the sleds. The film moves along the track, and the sleds move with the film while performing operations on the film. The system can have the sleds stationary while operating for an intermittent machine, and move to reconfigure when the film is moving. The operating stations include one or more of a sealer, a heater, a cooler, an inserter, a knife, a punch, a perforator, a static charger, and a printer. The track forms a continuous path or is linear. A controller controls the sleds and operating stations. The controller includes an operating time and/or a reconfiguration module. The operating time module is responsive to a user set material thickness or a sensed material thickness.

Abstract: A novel pressure-exchange ejector is disclosed whereby a high energy primary fluid transports and pressurizes a lower energy secondary fluid through direct fluid-fluid momentum exchange. The pressure-exchange ejector utilizes non-steady flow principles and both supersonic flow and subsonic flow embodiments are disclosed. The invention provides an ejector-compressor/pump which can attain substantially higher adiabatic efficiencies than conventional ejectors while retaining much of the simplicity of construction and the low manufacturing cost of a conventional ejector. Embodiments are shown which are appropriate for gas compression applications such as are found in ejector refrigeration, fuel cell pressurization, water desalinization, and power generation topping cycles, and for liquid pumping applications such as marine jet propulsion and slurry pumping.

Abstract: An electrical wiring system includes an electrical wire and an electrical safety device. The electrical wire includes at least one electrifiable conductor, first and second insulating layers formed on opposing sides of the at least one electrifiable conductor, first and second return conductors formed on the first and second insulating layers respectively, such that the at least one electrifiable conductor is at least substantially entrapped by the first and second return conductors, third and fourth insulating layers respectively formed on the first and second return conductors, and first and second grounding conductors respectively formed on the third and fourth insulating layers. The electrical safety device is coupled to the electrical wire and is operable to test the electrical wire for at least one of a short or a miswire. The electrical safety device tests the electrical wire prior to the electrification of the electrical wire or subsequent to the electrification of the electrical wire.

Abstract: An electrical wire includes at least one electrifiable conductor for delivering electrical power, a first insulating layer formed on one side of the electrifiable conductor, a second insulating layer formed on the opposite side of the electrifiable conductors, a first return conductor formed on the first insulating layer opposite the at least one electrifiable conductor, and a second return conductor formed on the second insulating layer opposite the at least one electrifiable conductor. The at least one electrifiable conductor is at least substantially entrapped by the first and second return conductors such that the distance between said at least one electrifiable conductor and each of said first and second return conductors is no greater than approximately 0.030 inches. At least one of the first insulating layer or the second insulating layer comprises a plurality of insulating layers.

Abstract: A secondary source of dispatch information is provided in the event of a failure of a primary source of dispatch information. The second source of dispatch information can be accessed electronically by service technicians in the field when the primary source of dispatch information fails so that service technicians do not have to contact operators in a central office to obtain the dispatch information. The secondary source of dispatch information can distribute the dispatch information in a number of ways including e-mail, web and other methods.

Abstract: An electrical wire includes at least one electrifiable conductor, and a return conductor formed around the at least one electrifiable conductor, such that the at least one electrifiable conductor is completely entrapped by the return conductor.

Abstract: A combination selector switch and infinite switch energy regulator provides a plurality of simmer voltages. An infinite switch energy regulator for adapting input voltage level to an average output voltage level is provided. This energy regulator has a rotatable shaft for adjusting the average output voltage level. An input voltage selector, such as an F switch, selects between a plurality of input voltages by actuation of a rotatable cam. The output of the input voltage selector is provided as an input to the infinite switch. The rotatable shaft is also operatively coupled to the rotatable cam and thus controls the input voltage selector as well as the infinite switch. The selective provision of two different voltage levels as an input to the infinite switch permits a plurality of simmer voltages when the unit is assembled in an electric range.

Abstract: A novel ejector, an ejector-refrigeration system, and a method of refrigeration are disclosed. The system is particularly well suited for the utilization of energy sources such as waste heat from automobile engines and solar collectors. Further, the system is compatible with the use of environmentally benign refrigerant such as water. Unlike conventional ejectors, the novel ejector disclosed in the present invention is designed to utilize the principal of "pressure exchange" and is therefore capable of attaining substantially higher levels of performance than conventional ejectors whose operating mechanism is based on the principal of "turbulent mixing".

Abstract: A computer controlled hot/cold water mixing valve in which the set point discharge water temperature is controlling by measuring the hot inlet temperature and the cold water inlet temperature and performing appropriate calculations with the computer based on the measured temperatures.

Abstract: A system having a microprocessor to provide an adjustable control of the temperature and pressure of water at the outlet of a single adjustable valve. The water temperature at the valve outlet is constantly monitored. A processor compares the actual water temperature with a specifically requested temperature for the water at the valve outlet, and provides signals to relays and a control circuit for a motor which adjusts the temperature of water by the relative proportions of hot and cold water discharged through the valving to the outlet. The system with the microprocessor provides a multi-speed control of the motor having variations in the speed of adjustment of the valve so as to effect a quick valve movement to a temperature in the vicinity of the desired temperature after which fine tuning provides the exactly requested temperature.
