Abstract: A surgical apparatus includes an instrument having an operative zone defined thereon for physical engagement with a patient's body tissue. The instrument has a foraminous outer shell disposed in the operative zone. The foraminous outer shell has a multitude of relatively uniformly dispersed, small perforations defined therein. The instrument has a fluid supply channel communicated with the perforations for diffusing a flushing fluid out of the perforations throughout the operative zone so that adhesion of tissue to the operative zone of the instrument is reduced. The flushing fluid preferably includes a cytotoxic solution and/or an anti-adhesive solution. Additionally, or alternatively, the outer surface of the instrument may be permanently coated with a cytotoxic material and/or an anti-adhesive material.

Abstract: A manifold system includes an array of conduit outlets fixed in position relative to each other. A fluid connector has two quick connect devices mounted thereon and communicated through a hollow handle, so that a selected pair of the conduit outlets can be placed in fluid communication with each other by simultaneous engagement of the quick connect devices with the selected pair of conduit outlets.

Abstract: A pivotal guide for a trailer hitch which guides a trailer socket to engage a hitch ball when the user forces the trailer guide to engage the trailer socket. A base plate is pivotally connected to a hitch bar, which when a trailer tongue engages a base plate the hitch ball attached to the base plate is raised to be positioned directly below the trailer socket. The base plate has a pair of guiding walls for horizontal positioning of the trailer socket. The guide further has two locking devices for securing the base plate to the hitch bar. A second locking procedure is one in which a latch and latch receiver are attached between the base plate and the hitch bar respectively, thereby allowing the base plate to automatically be secured with the hitch bar when the base plate is in the final position.

Abstract: A glass sorting machine optically sorts glass cullet according to different color characteristics by irradiating the cullet with red, green and blue light as the cullet are passed through a sensing region between a light source and light sensors responsive to the different light colors. The attenuation levels of the different light colors are measured by the sensors as the cullet passes through the sensing region. The machine analyzes the attenuation levels to determine the color characteristics of the cullet. A collimator is typically used to enhance shadow definition. In one embodiment, a pixel grid map is made of the sensing region and each cullet that passes through the sensing region. Mapped on to each grid is a red, green, and blue digital signal. Attenuated signals are compared against baseline values to determine the attenuation for given cullet. The pixel grid map may be used with a data erosion technique to compensate for refraction.

Abstract: A tilting container system suitable for use in the materials handling industry is described. The system includes a wire mesh container; and a pair of support legs pivotally mounted to the container at an end of the container. The support legs are spaced away from each other along the end of the container and are pivotally mounted to the container for movement between a raised and lowered position. The legs support the container in a tilted position when the leg is in a lowered position. The system can also include a pair of legs mounted to the container at an opposite end of the container from the pivotally mounted legs.

Abstract: A glass sorting machine optically sorts glass cullet according to different color characteristics by irradiating the cutlet with red, green and blue light as the cullet are passed through a sensing region between a light source and light sensors responsive to the different light colors.

Abstract: The internal combustion engine fuel system described includes a structure for mixing the alternative fuel, preferably hydrogen, with oxygen in ambient air to stratify the fuel. The system includes an adapter, and the adapter includes a housing mounted between spark plug and cylinder of the internal combustion engine. A plug is placed within the housing. The plug has ridges or grooves on its outer surface that act as mixing structures. Thus, when hydrogen is introduced into the adapter housing it is mixed with ambient oxygen within the chamber as it flows over the plug. The mixing structures in the housing creates a vortexing action as the hydrogen flows over the plug and towards the cylinder of the engine. An electrode protrudes from the plug towards the cylinder. The electrode is preferably platinum and generates the necessary spark to create combustion of the hydrogen/air mixture adjacent to the cylinder to thereby power the cylinder in the engine.

Abstract: A safety relief system for a CNG fuel supply of a vehicle includes first and second Type 4 cylindrical tanks, each having a shutoff valve at a first end and an outlet at a second end of the tanks. First and second relief devices are attached directly to the shutoff valve of the first and second tanks, respectively. Two separate relief outlet lines are connected to the outlets of the tanks. A common relief line is located generally parallel to and lying between the first and second tanks. The two separate relief lines are both connected to the common relief line. Third and fourth relief devices are connected to the common relief line. Each of the relief devices is constructed to relieve pressure on both the first and second tanks in response to either an excessive pressure or and excessive temperature at that relief device.

Abstract: A mobile separator system for receiving and separating a mixed composition of oil, water, and sludge. The mobile separator system including a tank for holding the mixed composition, and a drain manifold that includes a plurality of drain pipes extending into the tank at varying elevations for allowing the drainage of water from the tank system. A vacuum source is attached to the top of the tank for carrying a vacuum within the tank to draw the mixed composition into the tank. The drain manifold is surrounded by a screen that allows the passage of water and oil, while preventing the passage of sludge through the screen into the drain pipes. A floating check valve is connected to each of the drain pipes to regulate the flow of water through the drain pipe. The floating check valve includes a valve element that has a density which causes the valve element to float in water and sink in oil.

This mechanism includes a cylindrical shaft extending from the head, and having an eccentric cam follower lug extending transversely from the shaft. A mounting block has a cylindrical bore disposed therethrough, and the shaft is received through the bore of the mounting block. A cam piece is slideably disposed within the mounting block to rotate the shaft as the cam piece slides relative to the mounting block.

Abstract: The present invention relates to musical instruments and methods and apparatus for producing notes of a musical scale with real strings. More particularly, it relates to the division by frets, of the fingerboard, or neck, of a fretted stringed musical instrument, to obtain a desired musical scale with a specific set of strings. One embodiment of the invention is described in which the 12-tone equal-tempered scale is accurately produced on a guitar with steel strings having sufficient bending stiffness to cause audible intonation errors inherent in steel-stringed guitars of prior art. According to another embodiment of the invention, the musical scale is additionally tempered to approximate the 12-tone, equal-tempered scale while minimizing audible beats that occur when playing intervals and chords due to inharmonic frequency components inherent in tones generated by vibrating guitar strings. Manufacturing methods with respect to wound strings, and with respect to boundary conditions, are also explained.

Abstract: A Recreational Water Sprinkler apparatus includes a manifold having a water inlet and a plurality of manifold outlets. A plurality of elongated flexible discharge hoses are connected to the manifold outlets. The hoses are sufficiently long and flexible that when water is supplied at conventional household pressures, the water is discharged through the discharge hoses thereby causing the hoses to gyrate and whip back and forth in a random manner relative to the manifold, thus spraying water randomly in all directions within a hemispherical space around and above the manifold.
