The mat includes a flexible carrier sheet having an array of mutually spaced pegs projecting downwardly therefrom and a plurality of plugs. The plugs are externally configured and dimensioned to be inserted in and to seal the open mouths of the test tubes. Each of the plugs has an upwardly facing recess internally configured and dimensioned to receive and coact in frictional engagement with a respective one of the pegs to thereby releasably secure the plugs to the carrier sheet. The carrier sheet is separable from the thus inserted plugs by flexure to extract the pegs from the recesses.

Abstract: Methods are provided for processing and dispersing animal tissues that involve exposing processed (e.g., decellularized) tissue to an acylating agent, wherein the ratio of acylating agent to wet tissue weight is about 0.003:1 or less. Preferably, decellularized tissue is exposed to an amount of the acylating agent of about 0.1% to about 0.3% of wet tissue weight for a time ranging from about 30 seconds to about 10 minutes. A dispersed tissue matrix is produced that has a high degree of resistance to digestion by non-collagenase proteases, such as trypsin. In order to produce sufficiently high yields of these trypsin-resistant compositions, the processed tissue is preferably cryomilled to increase its surface area prior to acylation. The dispersed acylated decellularized tissue may be in the form of an injectable composition that can be introduced into tissue of a subject.

Abstract: An intermittent oscillation circuit is disclosed, and more particularly, relates to an intermittent oscillation circuit utilized in a RF transmitting/receiving system. The intermittent oscillation circuit of the present invention comprises an inversion circuit, a power control circuit and a power supply circuit. By utilizing the power control circuit to controlling the operation voltage level outputted from the power supply circuit, the duty cycle of oscillatory signal outputted from the inversion circuit can be adjusted. Therefore, data collision is decreased while transmitting/receiving various data in the RF transmitting/receiving system, and the power consumption is decreased at the transmitting/receiving terminal as well.

Abstract: An apparatus for mixing and spraying a catalyst with a resin onto a surface. The resin and catalyst are internally mixed within a disposable mixing tube. After the spraying is completed, the catalyzed resin is allowed to harden within the tube and the tube is thereafter disposed of. Because the catalyst and resin are not mixed within any reusable portions of the spraying apparatus, the need for rinsing with acetone or similar hazardous solvents is eliminated.

Abstract: An apparatus for mixing and spraying a catalyst with a resin onto a surface. The resin and catalyst are delivered to a mixer having no O-rings which could become clogged with catalyzed resin and destroy the gun. The manifold is connected to a mixer which is connected to an air supply. The spray gun eliminates the need for any check valves within the manifold.

Abstract: An apparatus for mixing and spraying a catalyst with a resin onto a surface. The apparatus is provided with a restricted orifice union on the resin line running into the manifold. The union traps large plugs of resin and prevents them from entering and clogging the manifold. The union is designed so that plugs of resin may be easily removed from the resin line with only a minimum of down time.

Abstract: An apparatus for monitoring and spraying a catalyst with a resin onto a surface. A pressure gauge is attached to the manifold of a spray gun to monitor the pressure of catalyst within the manifold. The pressure gauge warns of and diagnoses problems with the apparatus ranging from a damaged pump to a plug in the manifold.

Abstract: An apparatus for mixing and spraying a catalyst with a resin onto a surface. The resin and catalyst are internally mixed in confluence with pressurized air. The sprayer is provided with a specially designed check valve to prevent resin and catalyst from entering the pressurized supply line. The construction of the check valve prevents it from clogging or becoming stuck shut during operation.

Abstract: A gauging system includes a source of pressurized fluid, one or more fluid outlet means, each including a fluid line connecting the source of pressurized fluid with a fluid orifice that is located to measure small gaps and distances between the elements of a machine or die, and one or more pressure transducers connected to measure the pressure in each fluid line. One or more adjustable valves are provided between the source of pressurized fluid and each fluid line. A computer measures the transducer output to determine the distance between mold elements. The valve or valves include a threaded male member having an inlet at one end and a frustoconical surface with openings passing through it at the other, and a threaded female member having a channel in one end and an outlet in the other joined by another frustoconical surface.

Abstract: A molding system including a mold and a molding machine has been adapted to monitor the position of mold element surfaces that move relative to each other to form a mold cavity. The system includes a source of gas under pressure and orifice-forming sensors on a first mold element to direct a flow of pressurized gas from the first mold element. A monitoring system monitors the condition of the gas remote from the first mold element to indicate the spacing between the first mold element and one or more adjacent mold elements as the mold elements move with respect to each other.

Abstract: A font cartridge extrender into which a commerically available font cartridge can be plugged and which plugs into the font cartridge receptacle of a computer printer. The extender includes a novel latching mechnism which attaches the font cartridge to the extender so that the assembly can be conveniently plugged into, and unplugged from, the printer as a unit. The font cartridge is secured to the extender by a spring hook mechanism, which resides in a chute molded into the inside of the top portion of the casing of the extender. The spring hook mechanism is supported in the chute by braces and a pin molded inside the case which is inserted through an aperture in the spring hook mechanism. The spring hook mechanism is actuated by finger pressure on a contact surface.

Abstract: Cocaine addiction is treated by administration of an endorphinase or enkephalinase inhibitor, and optionally, a dopamine precursor, or a serotonin precursor, a GABA precursor, or an endorphin or enkephalin releaser. These components promote restoration of normal neurotransmitter function and are non-addictive. Use of the dopamine precursors L-phenylalanine or L-tyrosine, the enkephalinase inhibitor D-phenylalanine and/or the serotonin precursor L-tryptophan is especially preferred.

Abstract: A nozzle for a gap measuring system includes a short outlet passageway defined by a smooth, cylindrical wall terminating in an outlet orifice and having an entrance orifice surrounded by a wall portion that is substantially perpendicular to the outlet passageway. As fluid flows through the nozzle, it encounters the surrounding wall portion at the entrance of the short outlet passageway of the nozzle which constricts the fluid flow upon entry into the short outlet passageway of the nozzle. As a result of the nozzle geometry, the fluid exits the nozzle outlet with a higher velocity, lower pressure and decreased turbulence. The incorporation of such a nozzle into a gap measuring system can produce an increase in the reliability and accuracy of distance determinations nearly ten times that which was previously attainable with prior nozzle inserts.
