Abstract: The present invention reveals a method and apparatus for more efficiently injecting a primary fluid flow in a fluid ejector used to pump lower velocity fluid from a secondary source. In one embodiment, the primary fluid flow is a pulsed or unsteady fluid flow contained within an inner nozzle situated within a secondary flow field. This secondary fluid flow is bounded within the walls of an ejector or shroud. The secondary and primary fluid flows meet within the ejector shroud section wherein the secondary fluid flow is entrained by the primary fluid flow. The geometry of the ejector shroud section where the primary and secondary fluids mix is such as to allow the beginning of primary injector pulse to be synchronized with an acoustic wave moving upstream through the ejector initiated by the exiting of the previous pulse from the ejector shroud. The ejector's geometric properties are determined by the acoustic properties, frequency, duty cycle, and amplitude, of the pulsed primary fluid flow.

Abstract: An ice making device including a control system to regulate the dispensing of manufactured ice to a hopper for subsequent dispensing into a container such as a cup. The control system senses a low level of ice in the hopper and initiates a signal that is sent to a controller. The controller initiates a time delay that prevents discharge of ice from the ice making device to the hopper until a monitored variable about the ice meets a predetermined value. When the value is reached, additional ice is dispensed to the hopper. Such an ice making device has use in combination with a beverage dispensing device.

Abstract: The objects of the invention are provided using a method for horizontal drilling in which a shoe having an elbow-shaped cavity therein is lowered to a selected point. An explosive charge is placed at the far end of the shoe adjacent to the well casing. Impact transferring means are positioned between the explosive charge and the vertical portion of the well above the shoe. An impact is struck on the surface of the transfer means to cause an impact-type detonator to discharge, causing the explosive charge to discharge. This perforates the casing of the well at the tip of the shoe. The shoe and the tubing above it are then cleared and a hydraulic drilling device is inserted into the shoe. The shoe guides the hydraulic drilling device into place and high pressure liquid is pumped through the hydraulic device which extends through the perforation in the well casing into the earth's strata.

Abstract: A switch-mode power converter uses a digital signal processor (DSP) to control operation of power semiconductors through gate drive amplifiers, further using the DSP's internal analog-to-digital converters to measure necessary currents, voltages and timings within the main power circuit. Using values captured by the A-to-D converters, software controlling the DSP manipulates duty cycle and timing parameters of the main semiconductor switches to provide at least three different modes of operation for serving a wide range of lighting loads. This power system reduces the size, cost, and weight, of circuitry needed to operate stage lighting equipment. The DSP's microprocessor eliminates most of the complex and dedicated analog circuitry commonly used for electronic power conversion, and a common power circuit topology provides an identical hardware platform for each luminaire circuit. Overall reliability is enhanced because of the reduction in circuit complexity.
