Abstract: Embodiments of the invention provide a method for continuous flow production of mixed fluids. The mixed fluids can comprise a mixture of different fluids or a mixture of the same fluid having different input properties such as temperature. In general, two streams of fluid of varying temperature are supplied to a mixer. The flow rate of each of the input fluids can be regulated to produce a mixed fluid at a desired flow rate and temperature. As an example, mass flow controllers can regulate the flow rates of a hot and cold stream of de-ionized water to produce a stream of de-ionized water at a desired flow rate and temperature.

Abstract: An interactive system for assisting a user in the selection of ammunition based upon user entered parameters. A stand-alone kiosk includes a computer having a microprocessor and a memory, an input device in operative communication with the computer for permitting a user to enter parameters, and an output device in operative communication with the computer for providing information from the system to the user. A program is stored in the computer for execution by the microprocessor, the program interactively displaying a series of prompts on the output device, each prompt eliciting a response from the user concerning hunting parameters. The program stores the user inputted parameters in memory, applies predefined rules and/or recommendations against the user inputted parameters to thereby suggest advantageous ammunition, and displays the selected ammunition to the user on the output device.

Abstract: Embodiments disclosed herein provide a pump or a multiple-pump system that can mix chemicals without dilution tanks and can dispense the mixture of chemicals in a precise and highly controllable manner, particularly useful in semiconductor manufacturing processes. In some embodiments, one or more piston pumps of similar displacement are used to mix and dispense the chemical directly. A first valve is opened to a first chemical source. A piston is moved in a first direction to a selected position in a chamber to draw the first chemical into the chamber. The first valve is closed and a second valve is opened to a second chemical source. The piston is moved in the first direction to a second position in the chamber to draw in the second chemical and mix the chemicals. The second valve is closed and the piston is moved to dispense the fluids through a dispense port.

Abstract: The present invention relates to a kit for determining feline blood type, wherein the kit includes a mixture comprised of a first monoclonal antibody and a second monoclonal antibody, wherein both antibodies recognize feline blood group specific A antigens. The present invention also relates to a method for determining feline blood type, wherein the method utilizes two distinct monoclonal antibodies, which recognize feline blood group specific A antigens.

Abstract: Compositions useful for making lightweight roof tiles. The compositions comprise in percent by weight: between about 2.0 to 4.1 latex (solids basis), between about 20.0 to 28.0 cement, between about 28.0 to 55.0 lightweight aggregate, between about 9.0 to 15.0 water, between about 5.0 to 35.0 standard weight aggregate such as sand, between about 0.0 to 8.0 filler such as limestone, and between 0.0 to 1.5 accelerating additive such as calcium chloride. Methods for making the compositions e.g. into lightweight roof tiles, are also disclosed.

Abstract: A tool changer is provided in which a rotary tray positioned beneath the forward edge of a machine tool supports a large number of tools in individual cartridges. A tool changer head includes two outwardly projecting tubular members and can be rotated about a horizontal axis, moved vertically and pivoted about a vertical axis. A vacuum or positive pressure can be generated in the tubular members. Therefore, the tubular members can be positioned over a tool in one of the cartridges after which the tool changer head is raised and rotated to extend the tool into the spindle of a machine tool which has been run past the forward edge of the machine. Negative pressure will withdraw the tool from the cartridge and positive pressure will drive the tool into the spindle. Similarly, a tool can be removed from the spindle by negative pressure and reinserted into the cartridge by positive pressure.

Abstract: The present invention relates to a method to detect feline blood type B comprising: combining feline blood with a sufficient amount of Triticum vulgaris lectin to agglutinate feline blood type B. Additionally, this invention relates to a kit to detect feline blood type B.

Abstract: A steam-producing orchard heater operating on the pulse-jet combustion principle has a horizontal cylindrical combustion chamber with an exhaust tube of smaller diameter extending coaxially from one end thereof, an air supply and ignition tube, extending tangentially from the combustion chamber near the closed end, a fuel supply fitting in the combustion chamber in the same transverse plane as the air supply and ignition tube, and a water injection fitting near the exhaust tube end of the combustion chamber. Two legs are provided under the combustion chamber, and one leg is provided under the exhaust tube.

Abstract: A compound bearing consisting of an outer and an inner member movable relative to each other and between which are disposed load carrying annular members. The load carrying annular members comprise a pair of elastomeric rings held between the outer and inner members under compression, and a metallic ring insert disposed between and separating the two elastomeric rings. A narrow clearance is provided between the peripheral surface of the metallic ring insert and the inner surface of the bearing outer member, and between the metallic ring inner surface and the inner member peripheral surface. Normal loads are taken and absorbed by the elastomeric rings, while overloads and shock loads are taken by the metallic ring insert.

Abstract: A helical bearing bushing for use between a cylindrical shaft and an element containing a bore disposed around the shaft, such as a kingpin and steering knuckle assembly, includes a helically wound spring wire as the bearing bushing. The spring wire is helically wound to form a tubular member having interior and exterior surfaces which form the respective bearing surfaces. The tensile force of the helical spring holds arcuate surfaces of adjacent coils in elastic abutment, although lubricant under pressure can elastically separate the coils and pass from one surface to the other. Non abutting portions of the arcuate surfaces form helical lubrication grooves. Either the interior surface or the exterior surface, or both, may be machined flat to provide a better bearing surface.

Alternatively, the kingpin end portions and the internal surface of the bushing, preferably split bushing, are cylindrical and the bushing external surface is frusto-conical and disposed in a frusto-conical bore in the knuckle yoke. The bushing is pre-loaded in a direction causing engagement of the kingpin end and bushing bearing surfaces, being spring-biased or, in the alternative, by an end cap closing the yoke bore and having an annular position projecting within the bore.

Abstract: A motor vehicle steering knuckle and kingpin assembly comprising a kingpin fixedly mounted through the motor vehicle front axle or beam with the end portions of the kingpin projecting above and below the front axle or beam. A wheel spindle knuckle is pivotally mounted relative to the kingpin, the spindle knuckle having an upper yoke having a bore disposed around the kingpin upper end portion and a lower yoke having a bore disposed around the kingpin lower end portion, a bushing being installed in each of the yoke bores. The kingpin end portions have a frusto-conical peripheral surface and the yoke bushings have a cylindrical internal surface such that, under load, the bearing surfaces in engagement and capable of transmitting the load are along the whole length of the bearing surfaces. Alternatively, the kingpin end portions are provided with a peripheral cylindrical surface co-operating with an appropriate frusto-conical internal surface for the bushings.

Abstract: A wear indicator for knuckle or swivel joints of the ball and socket type wherein the spherical surfaces in swivelling engagement are urged in bearing engagement by a retainer member accomplishing the double function of holding the ball and the socket in assembly and of applying a pre-load force to the ball to prevent vibration and rattle and to compensate for wear of the bearing surfaces. The wear indicator is in the form of an elongate member attached to the pre-load retainer member at a portion thereof which is progressively movable in the direction of wear of the bearing surfaces of the joint for maintaining the pre-load pressure upon the bearing surfaces.
