Abstract: A system and method for injecting liquid/solid mixtures into porous pulse media, such as earth, is disclosed. A two-tank arrangement where liquid only is stored and run through a main pump, while a liquid/solid slurry is stored and moved to join the liquid under pressure by a chemical injector pump is shown. Finally, a displacement wheel commands solenoid valves, for pulsing the pressured liquid, through a distance measuring device such as a laser interacting with a laser target operatively coupled to a ground traveling wheel.

Abstract: A vending machine (10) is comprised of a platform assembly (110) encased by a transparent envelope (150) and supported by a anti-pilfering base (80) received within a housing (20). The platform assembly (110) includes a plurality of platforms (142) disposed about a helical path (260), and upon which articles to be vended are placed. A linkage assembly (170) includes a trigger means (210) and is operatively coupled between a latching mechanism (66) located within the housing (20) and at least one platform (142) to move the platform from a substantially horizontal plane to a substantially vertical downward position to discharge the article to be vended.

Abstract: A needleless dosage transfer system for filling medicating devices such as syringes or needleless cannulas to minimize the likelihood of an unwanted needle stick and to avoid the initial cost of a needle as well as the disposal cost of the needle. A vial has a body portion (20) formed with flexibly deformable walls and defines a blind bore. An opening of the vial includes a tapered section adapted to frictionally fit over a taper of a male luer-type fitting commonly found on syringes and needleless cannulas. By deforming the walls of the vial, fluid is forced from the vial into a syringe. The opening of the vial (10) is protected with a cap and includes a scoreline which, when fractured, defines the opening. The cap to be removed from the vial prior to its use is fabricated as one piece with the vial in order to assure sterile conditions during manufacture and filling. A tab is associated with the cap which lists the ingredients within the vial. The vial also supports an area which lists the vial's contents.

Abstract: The encapsulated transducer (10) includes an injection molded encapsulation (20) having a front end (22) and a back end (24). The encapsulation (20) ensconces a sensing element (40) proximate the front end (22) and a portion of a cable (60) which extends from the back end (24). The sensing element or coil (40) is electrically and mechanically connected to the cable (60) by a pair of suitably sized front and rear ferrules (80), (90) secured to a center and coaxial conductor (66), (70) of the associated cable (60) thereby forming a coil and cable assembly (110). At least the rear ferrule (90) includes a shoulder (100) for firmly anchoring the coil and cable assembly (110) within the encapsulation (20). In addition an injection molding process provides the durable encapsulation (20) which bonds with a dielectric (68) of the cable (60) and symmetrically locks the coil and cable assembly (110) therein.

Abstract: A fluid reaction device 10 is provided having a rotor 90 with vanes 92 pivotably connected thereto. The device 10 includes an entrance 30 for elevated pressure fluid and an outlet 40 for discharge of the fluid after contacting the rotor 90. The elevated pressure fluid passes from the entrance 30, into a high pressure chamber 80. The high pressure chamber 80 is in contact with inlet ports 74 accessing a cylinder 72 within the device 10. The cylinder 72 supports the rotor 90 with a rotational axis M of the rotor 90 off center with respect to a central axis N of the cylinder 72. The elevated pressure fluid causes the rotor 90 and an attached output shaft 97 to rotate. The rotor 90 includes a trunk 24 with a plurality of posts 93 extending therefrom and with vanes 92 connected to the posts 93 through hinges 94. The vanes 92 can pivot from a first position collapsed against the trunk 24 to a second position spaced away from the trunk 24.

Abstract: A hitch assembly is disclosed for use with endless track land vehicles that allows an implement mounted by a three-point hitch arrangement up to about 15 degrees arcing movement off the longitudinal axis oriented in the direction of travel of the land vehicle. A pivotal mounting means is connected to two horizontal arms which are joined at the rear by another member. The mounting means and connecting arms form a four-sided polygonal structure which can be raised or lowered by a hydraulic ram since the arms are pivotally connected at the corners. Finally, a telescoping linkage assembly, after the hitch assembly has been raised through 75 percent of its travel, urges the implement mounting means on the rear vertical connecting arm into a common, pre-selected travel position.

Abstract: The apparatus includes a funnel, connected to a section of clear hose. The clear hose has installed in line, 3 valves, for regulating water flow to the funnel for the process of separating gold from gold bearing soil.

Abstract: A method of making an encapsulated transducer (10), which includes an injection molded encapsulation (20) having a front end (22) and a back end (24). The encapsulation (20) is a monolith of cured moldable material ensconcing a sensing element (90) proximate the front end (22) and a portion of an information transmitting medium (120) emanating from the back end (24). A component alignment preform (40) operatively couples the sensing element (90) with the information transmitting medium or cable (120). The component alignment preform (40) includes a front ferrule (70) and a rear ferrule (80) bonded thereto and linearly spaced apart along a long axis "A". The component alignment preform (40) further includes an annular recess (44) in which the sensing element or coil (90) is placed so that it is linearly spaced and aligned along the common long axis "A" in which the front and rear ferrules (70), (80) are aligned.

Abstract: A disposable dental prophylaxis handpiece 10 is provided having a rotor 90 with vanes 92 pivotably connected thereto. The handpiece 10 includes an entrance 30 for elevated pressure fluid and an outlet 40 for discharge of the fluid after contacting the rotor 90. The elevated pressure fluid passes from the entrance 30, into a high pressure chamber 80. The high pressure chamber 80 is in contact with inlet ports 74 accessing a cylinder 72 within the handpiece 10. The cylinder 72 supports the rotor 90 with a rotational axis M of the rotor 90 off center with respect to a central axis N of the cylinder 72. The elevated pressure fluid causes the rotor 90 and an attached output shaft 97 to rotate. This in turn pauses a prophylaxis cup 160, coupled to the output shaft 97, to rotate. The rotor 90 includes a trunk 24 with a plurality of posts 93 extending therefrom and with vanes 92 connected to the posts 93 through hinges 94.

Abstract: A device which takes cut alfalfa laying in a field and turns it into a plurality of pressed cubes. A water spray conditions the cut alfalfa to have the right moisture content for subsequent processing. A pick up station delivers the alfalfa off of the ground and feeds it to an auger and paddle area for subsequent conveyance to a chopping station where the alfalfa is comminuted to the appropriate length. Thereafter, the chopped alfalfa is conveyed into a press where the cubes of alfalfa are formed by extrusion. Conveyors allow the formed cubes to be placed in a trailer hitched to the vehicle. By providing a vehicle which processes the alfalfa in the field, enhanced quality of the alfalfa cubes and efficiency results.

Abstract: A device for cryoprotecting thermolabile products. A container (20) receives an annular rack (40) which is sealed by an enclosure (60). The enclosure (60) includes an outer stationary toroid (70) and a rotatable core (90). A robotic arm (160) is adapted to move and is supported by the core (90). The robotic arm (160) accesses an interior of the enclosure (60). An access portal (80) allows removal and placement of thermolabile products constrained by a holder (150). The robotic arm (160) accesses product and holder (150) and embarks upon controlled freezing of the product and its location in the rack (40) until subsequent retrieval. A computer controls the rate of freezing and stores in memory the location of all of the stored products. The robotic arm (160) reads the product in storage to assure the correct product is being accessed.
