Abstract: A fuel dispenser is disclosed. The fuel dispenser has a housing which contains two chambers, one contains a computer and the other the hydraulic parts of the dispenser. Fiber optic cables connect a fiber optic switch which detects the cradling of a nozzle to a computer, and other fiber optic cables connected to a pulser signal the flow of fuel in the meter of the dispenser to the computer. The computer controls a liquid crystal display which prompts the customer to actuate keys on a keyboard adjacent to the display. A pivotal boot supported by a horizontal shaft receives the nozzle. This boot pivots to permit better access to the hydraulic area of the housing. The shaft, itself, is rotatable to actuate a switch to indicate, through fiber optic cable, to the computer that the nozzle is stored and to shut down pumping. A fiber optic pulser feeds light signals to the computer for indicating the flow of fuel through the meter.

Abstract: A cleaning apparatus cleanses a portable keg tap for a keg of a beverage, such as beer. A keg tap coupling has an orifice which emulates a fluid outlet orifice of a keg. The keg tap coupling is connected to the inlet of a portable keg tap. A cleaning fluid coupling is disposed to connect to a cleaning fluid source, for example, a water spigot or water outlet from a water heater. A fluid regulator regulates the fluid pressure of the cleaning fluid flowing from the cleaning fluid source. A shut-off valve is used to selectively initiate and terminate the flow of cleaning fluid flowing from the cleaning fluid source. As a result, a portable keg tap can be efficiently cleaned and sanitized.

Abstract: Soffits for interior construction purposes are preformed from L-shaped foam material having insert furring strips for attaching the soffits to walls and ceilings. The preformed soffits are brought to the job site, quickly cut to length, fastened in place, and then covered with plasterboard before cabinets are mounted below.

Abstract: An improved navigational plotting system having convenient initialization and the ability to compute and superimpose hyperbolic time difference lines on a chart includes an X-Y plotter for plotting the position and course of a vessel on a navigational chart or a plain piece of paper, dictated by the reception of hyperbolic navigation signals. Ambiguity-free conversion to latitude and longitude is done automatically without the necessity of manually entering the initial latitude and longitude of the vessel. Remote initialization is established by placing the pen of the plotter on a known point or position on the chart and entering the latitude and longitude of this known position or its hyperbolic navigation coordinates, with all subsequent plot locations being referenced to this point on the chart. A set of default pre-stored conditions are utilized in the initialization procedure in which preset scale size and hyperbolic line parameters are assumed, with convenient override sequences being provided.
