Abstract:
A conveying system is provided for moving a pallet along straight and curved paths. The conveying system includes a track on which the pallet is mounted for movement by a motor driven roller which engages a stationary shaft mounted on the track. The drive roller is urged into contact with the shaft and is capable of clockwise and counterclockwise rotation in order to effectuate forward or reverse motion of the pallet. A control device is provided for controlling the speed and stopping and starting the pallet. The control device may include object detectors and/or switches for stopping the pallet in response to objects on the track or for stopping the pallet at predetermined locations.
Abstract:
Disclosed herein is a three-element gas tube fail-safe station protector of known design modified to incorporate a back-up air gap system. To the ground terminal stud of the protector is added a lateral conductive member defining a pair of blade-shaped ground electrodes. To each of the line electrode terminal studs is added a conductive blade-shaped electrode which overlaps and is spaced from a respective one of the ground electrodes. The air gaps which are thus defined between ground and each line, i.e. paralleling the gas tube gaps, are encapsulated and dimensioned to provide back-up ionization in the event of a failure of the gas tube.
Abstract:
The present invention relates to uses and methods for the detection of a quantitative difference between first and second target sequence regions present in a nucleic acid sample, in particular but not exclusively a DNA sample, and a kit for carrying out the uses and methods of the invention.
Abstract:
A germicidal composition comprising an aromatic dialdehyde; a medium chain linear alcohol; a surfactant; at least one enhancer selected from the group consisting of a halide salt, a carbonate and a carboxylate salt; and water, wherein the germicidal composition is a microemulsion.
Abstract:
A method and system for evaluating the durability of spark plugs. A test system simulates the pressure, temperature, and exhaust flow of an internal combustion engine, and has a test chamber in which these simulated conditions exist. A number of spark plugs are installed in the test chamber and are cycled through a desired ignition cycle. The test chamber temperature and pressure may be precisely controlled, as well as the duty cycle of spark events.
Abstract:
A valve for a gas-driven motor and a valve assembly and reciprocating pump incorporating the valve are provided. The valve includes a shiftable valve for alternatively supplying a motive gas through first and second supply ports to opposed first and second power pistons in opposed motive gas chambers, respectively, and for effecting alternating exhaust of said chambers. The shiftable valve has a front face with a valve projection located thereon and a rear face with a valve projection located thereon.
Abstract:
Germicidal compositions including a phthalaldehyde and methods of using such compositions for killing bacteria, disinfection, or sterilization, are disclosed. In one aspect, a germicidal composition may include a diluent, a germicidal compound, such as phthalaldehyde, and an amount of isophthalaldehyde to enhance the germicidal efficacy of the germicidal compound. In the case of phthalaldehyde, the composition may have a staining property that is less than a staining property of a composition consisting essentially of phthalaldehyde diluted to the same concentration. In another aspect, the composition may further include an amount of terephthalaldehyde to enhance the germicidal efficacy of the phthalaldehyde. In yet another aspect, a germicidal composition may include a diluent, phthalaldehyde, and a material such as isophthalaldehyde, terephthalaldehyde, or a combination of isophthalaldehyde and terephthalaldehyde, in order to reduce a staining property of the phthalaldehyde.
Abstract:
A pair of closely adjacent electrically conductive coils, suitably encapsulated, are secured to or retained closely adjacent an electrical accessory and a fuel line of an internal combustion engine. When the engine is utilized to drive a rubber-tired motor vehicle a ground strap is provided to provide an electrical connection around the insulation produced by the rubber tires and the rubber motor mounts of the engine.
Abstract:
Disclosed herein are α-Hydroxy sulfonate aldehydes and synthesis methods therefor. Germicidal compositions including the α-hydroxy sulfonate aldehydes, are also disclosed. In one aspect, a germicidal composition may include a diluent, and a germicidally effective amount of a water-soluble germicidal compound including an aldehyde group and an α-hydroxy sulfonate group. The water-soluble compound may have a solubility of at least 5 (w/v) % in water. In a further aspect, the compound may include 1-hydroxy-3-oxo-2-phenyl-propane-1-sulfonic acid salt, (2-formyl-phenyl)-hydroxy-methane sulfonic acid salt, 1-hydroxy-2-(4-methanesulfonyl-2-nitro-phenyl)-3-oxo-propane-1-sulfonic acid salt, 2-bromo-1-hydroxy-3-oxo-propane-1-sulfonic acid salt, 2-chloro-1-hydroxy-3-oxo-propane-1-sulfonic acid salt, 2-(1-formyl-2-hydroxy-2-sulfo-ethyl)-isonicotinic acid salt, 2-benzooxazol-2-yl-1-hydroxy-3-oxo-propane-1-sulfonic acid salt, or 1-hydroxy-2-(4-methoxy-phenyl)-3-oxo-propane-1-sulfonic acid salt. Germicidal compositions including a mixture of an α-hydroxy sulfonate aldehyde and one or more phthalaldehydes, such as phthalaldehyde, isophthalaldehyde, terephthalaldehyde, or a combination thereof, are also disclosed. Methods of using the compounds or compositions for killing bacteria, disinfection, or sterilization, are also disclosed.
Abstract:
Germicidal compositions containing phenylmalonaldehyde-type compounds, or mixtures of phenylmalonaldehyde-type compounds and phthalaldehydes, and methods of using such compositions for killing bacteria, disinfection, or sterilization, are disclosed. In one aspect, a germicidal composition may include a diluent, and a germicidal compound having the formula: wherein Ar is an aryl group that is selected from the group consisting of phenyl, 4-pyrimidinyl, and 2-(2-nitro-3-formyl-phenyl). In a further aspect, the composition may also include a germicidal efficacy enhancer such as isophthalaldehyde or a combination of isophthalaldehyde and terephthalaldehyde.
