Abstract: In a high pressure fluid system for providing fluid to a hand held nozzle, an improved power assisted dump valve which may be remotely located and controlled. The dump valve includes a stepped piston positioned in a stepped bore with one end of the piston adapted for sealing off a pressure relief outlet. A fluid conduit, preferably a passageway through the piston, conducts high pressure fluid to the valve chamber at the large diameter end of the piston. A control valve either seals off the large diameter end of the chamber or vents it to ambient pressure so that differential pressure supplied by the working fluid itself drives the valve piston to its open or closed positions. An electrical, hydraulic, or mechanical actuator operates the control valve, remotely if desired, to control the flow of high pressure fluid to the nozzle.
Abstract: An apparatus for cutting vegetation with a rotating head carrying a flexible, non-metallic cutting line extended radially into a cutting plane. An additional length of line is extended into the cutting plane automatically during rotation of the head as its speed increases from a first magnitude to a second magnitude. A laterally displaced cam within the head moves outwardly for releasing a spool carrying coiled cutting line to advance a first angular displacement within the head. The spool rotates a second angular displacement to return the cam to its original position by the drag of the cutting line during vegetation cutting but not by free air travel. After the cutting line length extension is completed, the spool is secured by the cam at its initial position automatically against further rotation within the head.
Abstract: An impeller is rotatably mounted in a housing on the lower end of a sub which is lowered by means of a wire line into a bore hole. The fluid flow in either direction within the bore hole engages and rotates helical vanes of the impeller, which in turn rotates a digital sensing device. A magnetic coupling links the impeller to the sensing device which is sealably secured within the housing. Rotation of the sensing device in one direction produces a digital output signal which is distinguishable from the output signal produced when the sensing device is rotated in the opposite direction. The digital signal is produced by the rotation of a butterfly valve between signal emitter elements and signal receiving elements coupled to a distinguishing logic circuit. The direction of flow of fluids along the bore hole is thus easily detected in a reliable, highly sensitive manner.
Abstract: A meat cutlet tenderizing machine having first and second sets of coacting roller cutters between which a meat cutlet is fed is disclosed. The coacting roller cutters of each set are arranged in parallel pairs with rotary tenderizing knives mounted in axially spaced relation on each roller cutter. The second set of roller cutters are vertically spaced with respect to the roller cutters of the first set to permit a meat cutlet to be engaged and perforated simultaneously by the rotary tenderizing knives of both first and second sets as the meat cutlet advances through the coacting roller cutter pairs. The coacting roller cutters are driven by a chain and sprocket assembly in which the drive sprocket coupled to the roller cutters of the second set has a greater number of sprocket teeth than the drive sprocket coupled to the roller cutters of the first set thereby causing the rotary tenderizing knives of the second set to rotate at a faster rate relative to the rotary tenderizing knives of the first set.
Abstract: Disclosed is a system for irradiating living bodies, or portions thereof, using electromagnetic radiation (EMR). A source or generator provides electromagnetic energy at a selected frequency, within an operational band width, via a coaxial cable to an applicator for radiation into living tissue. The source, cable, and applicator each have a characteristic impedance approximately equal to the average impedance of the living tissue over a broad frequency band, thus enabling efficient operation of the apparatus without using auxiliary impedance matching devices. The applicator is of a waveguide transmission line type enabling efficient transmission and radiation of the electromagnetic energy and further incorporates means for cooling surface portions of the living tissue during radiation thereof. Selective dielectric loading of the applicator enables shaping of the radiated power to a preselected distribution.

Strobe signals which are applied to the driver conductors are counted during the alternate scan intervals for selecting a day temperature different from a night temperature, for selecting the times which divide night from day and for providing set-back to night temperature during a predetermined time of the day.
Abstract: A method for manufacturing an artificial rose bud primarily from a rectangular fabric section. With the rectangular fabric section positioned with a short side on the right, the right edge is folded down to a position near the lower edge to form a bias fold extending from the lower right-hand corner to a point on the top edge near the upper left-hand corner. The upper left-hand corner is then folded to a point near the lower left-hand corner and between that corner and the folded position of the upper right-hand corner. The lower right-hand corner is then folded to a point near the lower left-hand corner and between that corner and the folded position of the upper left-hand corner. The left and lower edges are then pleated and thereby formed into a bundle about the lower left-hand corner of the fabric section. A small diameter shaft forming a stem is preferably positioned on the fabric section before the first fold is made so that after pleating, the bundle is formed about the shaft.
Abstract: A valve for automatically dumping a load of solids entrained within a fluid transport medium in response to flow interruption is disclosed.
