Abstract: A system and method for providing weed extraction so Industrial, Commercial and Home users (ICAHUs) can assure that unwanted weeds can be easily and effectively extracted. The system and method allows ICAHUs to work safely and efficiently and to extract weeds by using a hand-held device that can easily penetrate the ground around weeds, secure the unwanted weed, and aid the user in extracting the weed from the ground. ICAHUs can easily operate the levers of the device which operate jaws to secure to weeds. Specialized debris passages in the jaws of the device allow for debris to be passed through the jaws of the device which allow to for continued use and a greatly reduced need to clean the device during use. The method comprises a system in which unwanted weeds may be easily secured and extracted by the user without an increased risk of accidents or without unnecessary steps or procedures for cleaning.

Abstract: The present invention is a drop-down extra axle and wheel set for a utility truck. The extra axle and wheels are pivotally connected to an extra frame set that overlies and/or extends along the original frame for the truck, from the back end of the truck frame to near its midpoint just behind the cab of the truck. The extra frame set is a generally horizontal, rectangular piece that lays over the top of, and/or extends along, from the back end of to just behind the cab of, the original truck frame. The extra frame set has a trailing, extra, axle support assembly near its back end. The extra axle support assembly depends down from the extra frame, and supports an extra axle and wheel set at its bottom. A set of pivoting connecting rods extend forwardly from the bottom of the extra axle support assembly to pivot brackets which also depend down from the extra frame several feet forward of the extra axle support assembly.

Abstract: A process of extracting liquid from a fabric having a first content of liquid includes the steps of creating a surfactant surface layer including at least one surfactant at an air-liquid interface of the liquid on the fabric, wherein the surface layer has a first surface tension, and adding at least one co-surfactant different from the surfactant. The surfactant and said co-surfactant have substantial chain length compatibility. The co-surfactant reduces the surface tension at the air-liquid interface. The fabric is then subjected to mechanical extraction for a period of time to reduce the liquid content of the fabric from the first content of liquid to a second liquid content.

Abstract: An internal combustion engine (14) has an associated controller (18) controlling operation of the engine. A fuel pump (10) delivers fuel to the engine at more than one pressure (300 kPa, 800 kPa). The fuel pump includes a fuel inlet (34) and a fuel outlet (68). It also includes a motor (38) and pump assembly (36) for drawing fuel through the inlet into the fuel pump and delivering fuel to the outlet at a pressure higher than the pressure at the inlet. An outlet assembly (40) of the pump includes an outlet pressure sensor (76) and a processor (79) which is responsive to an input from the controller to vary the outlet fuel pressure by controlling the speed of the motor.

Abstract: A system for determining the depth of a fluid in a storage tank. The depth of the fluid is determined after the detection of a pulsed wave that is reflected from the top surface of the fluid. The system includes a transducer, an analog-to-digital converter, and a filter. The transducer is configured to sense the reflected pulsed wave and to generate an analog input signal that corresponds to the reflected pulsed wave. The analog-to-digital converter is coupled to the transducer, and configured to convert the analog input signal into a digital input signal. The filter is coupled to the analog-to-digital converter. The filter includes a finite impulse response filter that is configured to receive the digital input signal and to generate a digital output signal.

Abstract: A multi-stage turbine fuel pump (10) for automotive vehicles includes an inlet section (12) through which low pressure fuel is drawn into the pump, a first pump stage (14a) and a second pump stage (14b), and an outlet section (16) through which high pressure fuel is discharged from the pump. Components (13, 22a and 22b) comprising a pump inlet and respective first and second pump stages are aligned together by spring pins (32) inserted in open channels (36, 38, 44a and 44b) extending through the components so to improve fuel flow through the pump and prevent fuel leakage between the stages. Each pin has a hollow, cylindrical shape with a longitudinal slot (34) extending the length of the pin. The pins are made of a spring material, and each pin is compressed when inserted in place for the pin to thereafter press against a sidewall of the channel in which it is inserted, the force exerted by the pin on the channel sidewall maintaining alignment of the components.

Abstract: Each snow-gun site of a multisite snow-making system is equipped with a microprocessor-based logic and control unit. The latter responds to time-varying signals representative of the ambient temperature and relative humidity of its associated site to continuously adjust the flow rate of water applied to the snow gun(s) of such site in order to maintain a desired snow consistency. Based on the instantaneous values of temperature and relative humidity, the logic and control unit determines a nominal water flow rate value which, for the particular parameters of the snow-making system, will produce a desired snow consistency. This nominal value is compared with the present water flow rate value to produce a control signal used for adjusting a motor-controlled valve which determines the water flow rate applied to the snow-gun. The nominal water flow rate value can be selectively adjusted, on site, to account, for example, for gradual changes in system parameters, e.g.
