Abstract:
An acoustic driver assembly for use with any of a variety of cavitation chamber configurations, including spherical and cylindrical chambers as well as chambers that include at least one flat coupling surface. The acoustic driver assembly includes at least one transducer, a head mass and a tail mass. The end surface of the head mass is shaped to limit the contact area between the head mass of the driver assembly and the cavitation chamber to which the driver is attached, the contact area being limited to a centrally located contact region. The area of contact is controlled by limiting its size and/or shaping its surface.
Abstract:
A plastic bag for use with a coin sorting machine includes a front panel and a back panel sealed to the front panel. The front and back panels form a storage compartment therebetween and define an opening at an upper margin of the front panel. The opening is sized and shaped to receive coins from the coin sorting machine. The opening extends inwardly from one of a first side margin and a second side margin of the plastic bag and has a width which is less than an entire width of the plastic bag.
Abstract:
An acoustic driver assembly for use with any of a variety of cavitation chamber configurations, including spherical and cylindrical chambers as well as chambers that include at least one flat coupling surface, is provided. The acoustic driver assembly includes at least one transducer, a head mass and a tail mass. The end surface of the head mass is shaped so that only a ring of contact is made between the outer perimeter of the head mass of the driver assembly and the cavitation chamber to which the driver is attached. The area of the contact ring is controlled by shaping its surface.

Abstract:
A method of assembling multiple port assemblies in a cavitation chamber is provided. The method is comprised of boring at least two ports of different sizes in a cavitation chamber wall of the cavitation chamber. The external port diameter of the smaller port is smaller than that port's internal port diameter. A member selected from the group consisting of windows, plugs, feed-throughs, sensors, transducers and couplers is inserted into the chamber through the larger port and positioned within the smaller port. The member can be secured within the smaller port with an adhesive. A mounting ring/retaining ring, retaining coupler or port cover seals the second, larger port. A second member selected from the group consisting of windows, plugs, feed-throughs, sensors, transducers and couplers can be positioned within a cone-shaped port within the mounting ring or retaining coupler. A feed-thru, sensor, transducer or coupler can be integrated into the port cover. To aid the assembly process, specialized tools can be used to position the member within the smaller port.
Abstract:
A method and apparatus of circulating cavitation fluid within a cavitation fluid circulatory system is provided. The system provides a means of circulating the cavitation fluid through a cavitation chamber, before or during cavitation chamber operation, as well as a means of draining and filling the chamber with minimal, if any, exposure of the cavitation fluid to the outside environment. The apparatus includes a network of conduits coupling the cavitation chamber to a cavitation fluid reservoir and at least one external fluid pump. Preferably the cavitation fluid reservoir serves the dual function of fluid reservoir and degassing chamber. Manipulation of various valves within the conduit network allows the cavitation fluid to either be pumped from the reservoir into the cavitation chamber or from the cavitation chamber into the reservoir. During cavitation chamber operation, the same pump and conduit network can be used to continuously or intermittently circulate the cavitation fluid through the degassing system. A vacuum pump coupled to the degassing system can operate continuously or intermittently during system degassing. In another aspect, the cavitation fluid circulation system includes a bubble trap immediately following the fluid pump, thus providing a means of capturing bubbles generated during the pumping operation. In yet another aspect, the cavitation fluid circulation system includes a filter, preferably for removing contaminants that could disrupt the cavitation process. In yet another aspect, the cavitation fluid circulation system includes a heat exchange system, thus allowing the temperature of the cavitation fluid to be controlled.
Abstract:
A portable printer which can be removably attached to a variety of models and types of portable devices, such as Personal Digital Assistants (PDAs), cell phones, or other terminal devices. The portable devices can be attached to the portable printer via a clip-on adapter, thereby providing a universal clip-on printer. The adapter can take on a variety of shapes to hold the device and is unique for the model and type of each portable device, and contains mating electronic interconnectivity to electrically, wirelessly, or optically connect the portable device to the portable printer to enable communication between the portable device and the portable printer. The portable device connected to the portable printer can operate the portable printer in a controlling relationship.
Abstract:
Method and system for obtaining and using observed market rates in estimating suitable market-based compensation for one or more jobs. Each observed market rate is assigned a job family and a combination of a job category and a job level of responsibility (C/L). Median market rates and average market rates are observed for different job families and are combined in a novel way to produce job family factors and C/L factors that, when multiplied together accurately reflect market rates for that job, even for a combination of job family and job C/L that is not represented in the data.
Abstract:
A distributor insert screen cover adapted for use both as a particulate bay screen cover and as a lightweight and stable distributor insert stand. A screen is provided in multiple panels that span portions of an open, particulate bay top wall. The panels may be fitted together when removed from the particulate bay to form a stand having a footprint or base of sufficient width to provide improved stability and to allow support of the distributor insert at a height sufficient to allow suspension of a lowly disposed release element above the ground. Simplified versions having fewer or alternative stand components are also disclosed.
Abstract:
A lubrication system for lubricating bearings that includes at least one lubrication pump for pumping lubricant to the bearings and at least one metering valve for distributing the pumped lubricant throughout the lubrication system to the bearings. The system further includes a lubrication controller in communication with the at least one lubrication pump and at least one metering valve for controlling the lubrication system. The controller has firmware configured to provide a sequence of instructions to perform specified tasks and hardware that carries out the sequence of instructions to perform the specified tasks. In an unconfigured and unconnected state, the lubrication controller can be configured by reprogramming the firmware, to selectively control at least one of a series progressive lubrication system, a dual line lubrication system and a single line parallel lubrication system.
