Abstract: Reversible protectors are normally utilized to protect the leading edge of a work member from high wear during use. It is also advantageous to have a reversible protector that can be secured to a work member even though the work member may be composed of several components which are welded together thus adversely affecting the tolerances between the various components. In this subject arrangement, a reversible protector is provided and adapted to be mounted on and secured to a work member. The reversible protector has recesses located in the lower end thereof which, when assembled, are in mating engagement with protuberances on the work member. This mating engagement secures the lower end of the reversible protector to the work member. A pair of aligned openings are provided near the other end thereof which aligns with a transverse hole in the work member for receiving a retaining mechanism therethrough. The protuberances on the work member are protected from wear during use by respective lugs on the reversible protector that are located, when in use, directly adjacent the protuberances. The lugs also protect aligned openings in the reversible protector since the aligned openings are located behind and adjacent the respective lugs.

Title: High performance head assembly for an internal combustion engine
Inventor: SMITH RICHARD WILLIAM JR
IPC: F02F1/42
Filed: 1994-09-16
Granted: 2005-11-22
Abstract: A cylinder head assembly for an internal combustion engine. The cylinder head assembly has a deck surface for engaging an opposed deck surface on an engine block. A combustion chamber is recessed in the cylinder head assembly for each cylinder, and the combustion chambers each have first and second wedge portions. A first valve port penetrates the first wedge portion, and a valve seat is provided in the first valve port. The first valve seat is disposed at a first angle relative to the deck surface. A second valve port penetrates the second wedge portion, and a valve seat is provided in the second valve port.  The second valve seat is disposed at a second angle relative to the mounting surface. The second angle is less than the first angle. Each valve seat has a valve element for controlling the ingress and egress of gas flowing to and from the chamber.  The wedge portions permit a more erect valve orientation for the intake valve such that less scavenging of the fresh fuel/air charge will occur. The wedge portions also permit the exhaust valve and intake valve to moved to more advantageous locations relative to the combustion chamber. The relocation of the valves allows a more efficient placement of the spark plug, resulting in more even loading of the piston during the power stroke. The inlet passage which directs the fuel/air mixture to the combustion chamber has an independently unique configuration that improves atomization of the fuel/air mixture to achieve improved fuel economy and/or increased brake horsepower output.

Title: Structure and method for differentiating one object from another object
Inventor: BECK JIM
IPC: G01N21/27
Filed: 1993-07-27
Granted: 1999-09-21
Abstract: An apparatus and a method are provided for selectively eliminating weeds in agriculture operations. To provide selective elimination, at least two light (radiation) emitters (201, 202), powered by an internal power source, are modulated to switch on and off at very high speeds. Each emitter emits radiation of a different emitter wavelength. The on/off modulation of one emitter is phase shifted by approximately 90 degrees with respect to the modulation of the particular spot on the ground. The light beams (203, 204), provided by the emitters, are reflected off a plant (206) or the soil and are intercepted by a photodetector. Because plants have a characteristic spectral reflectance in regions of the electromagnetic spectrum which can be discriminated from the spectral reflectance of the background earth, the relative amplitudes of the reflected radiation at the two emitter wavelengths varies depending on whether the radiation is reflected off a plant or the soil. A ratio of the radiation at the two emitter wavelengths received by the photodetector is converted to phase. This phase is compared to an initial reference phase of the modulation of one of the emitters. A controller (221) uses this phase information to determine the presence or absence of a plant and then eliminates the weed.

Abstract: In a process for manufacture of a chemical product, a reactive hydrocarbon feedstream, which varies in composition of the reactive component, is combined with a compatible but unreactive hydrocarbon feedstream to form a blended hydrocarbon stream which is then combined with a reactive alcohol stream of stable concentration of its reactive component, to form a complete feedstream to the reactor. A desired ratio of relative reactant concentrations in the complete feedstream to the reactor is maintained by a control system which maintains a stable concentration in the blended hydrocarbon stream by manipulating flow rate of the unreactive hydrocarbon feedstream responsive to a concentration measurement in the blended hydrocarbon stream. Flow ratio control is then applied to maintain a desired ratio of reactants in the complete feedstream for the reactor by calculating a flow ratio of the blended hydrocarbon stream to the reactive alcohol feedstream. The calculated flow ratio is the process variable input to a manually set ratio controller which manipulates the flow rate of the reactive alcohol feedstream responsive to the flow ratio.

Abstract: Coordination of the overcurrent/time trip characteristics of a hierarchy of overcurrent protection devices is accomplished through a central tester whichestablishes a pattern of test currents for the individual overcurrent protection devices which simulates a fault at a specified location in the power system.  The individual assigned test currents are transmitted over a communications link to the separate overcurrent protection devices where they are stored in memory.  The central tester then broadcasts a test signal which simultaneously initiates testing of all of the overcurrent protection devices using the assigned test currents stored in memory.  The trip times are recorded and reported back to the central tester for analysis.
