Abstract: A water sports equipment storage rack includes first and second seats configured to receive a water sport device, an first engagement member aligned with the first seat and a second engagement member aligned with the second seat where each engagement member is configured to linearly move outward and inward with respect to the seat between an extended and retracted positions and to rotatably move about a pivot axis between an open position where the engagement member is spaced from the water sport device and a closed position where the engagement member abuts the water sports device thereby securing the water sport device within the storage rack, and a first drive mechanism configured to linearly move the first engagement member between the extended and retracted positions and rotatably move the first engagement member between the open and closed positions.

Abstract: A water sports equipment storage rack includes a seat configured to receive a first portion of a water sport device, an engagement member configured to linearly move in outward and inward directions between extended and retracted positions and to rotatably move about a pivot axis between an open position where the engagement member is spaced from the water sport device and a closed position where the engagement member abuts the water sport device thereby securing the water sport device within the water sports equipment storage rack, and a drive mechanism configured to linearly move the engagement member in the outward direction during a first portion of the linear movement of the engagement member and configured to rotatably move the engagement member from the closed position to the open position during a second portion of the linear movement of the engagement member.

Abstract: A water sports equipment storage rack including at least one U-shaped support, a claw, a drive mechanism, and a biasing member. The claw is (i) configured to move in an outward direction and in an inward direction and (ii) rotatable about a pivot axis between an open position and a closed position. The drive mechanism is configured to linearly move the claw in the outward direction and the inward direction. The biasing member is configured to (i) impart a biasing force to rotate the claw about the pivot axis in a direction toward the closed position and (ii) reduce the biasing force as the claw approaches the end of its linear travel, allowing the claw to move to the open position.

Abstract: A method of making N-(2,4-dinitrophenyl)-4-nitrobenzamide from a mixture of 2,4-dinitroaniline, 4-nitrobenzoyl chloride, and solid acid catalyst in an organic solvent, wherein the solid acid catalyst is not soluble in the organic solvent, the solid acid catalyst being an acidic clay, an ion exchange resin, a beta zeolite, a sulfonated tetrafluoroethylene-based fluoropolymer-copolymer, or some mixture of these.

Abstract: An induction heating apparatus includes a susceptor defining a reaction chamber. A housing is spaced from the susceptor opposite the reaction chamber and defines a port. A void space is defined between the housing and the susceptor. An induction coil extends through the port and is disposed within the void space for conducting an electric current to heat the susceptor to heat the reaction chamber. A flange comprises a metal material and is coupled to the housing at the port for sealing the port with the induction coil extending through the flange. An isolator is disposed between the flange and the housing to prevent the electric current from passing into the housing.

Abstract: Described are aromatic amino compounds that are useful to methods of carbon dioxide and sulfur dioxide removal.

Abstract: Aromatic compounds such as o-xylene are selectively nitrated by nitric acid in the presence of polyphosphoric acid and a large pore, acidic zeolite or a large pore, hydrophobic molecular sieve. This is an environmentally friendly, commercially viable, high conversion process for the selective nitration of aromatic compounds in the para position.

Abstract: A process for the purification of fluoroalkanesulfonate salt comprising (a) contacting a mixture of said salt and an inorganic salt contaminant with a solvent to selectively dissolve said fluoroalkanesulfonate salt in solution, and (b) isolating the solution, to yield a fluoroalkanesulfonate salt containing less than 500 micrograms of inorganic salt contaminant per gram of fluoroalkanesulfonate salt, or containing less than a maximum of 0.3% by weight of individual solvent.

Abstract: A device for tracing electrical cable. The device allows a cable installer or service person not only to identify one wire or cable in a group, but to simultaneously remotely identify as many cables as he desires. The device requires only that the installer connect a test device to each of the cables which he wishes to identify. Additionally, this identification is extremely easy to accomplish, as the “Identifying label” is in the installers own spoken words, and can be heard at the remote end by using existing industry standard test equipment (i.e.: an installer's test set, phone, headset, or amplified probe).

Abstract: A process that can be used for manufacturing a tetraalkylonium perfluoroalkylsulfonate is provided. The process comprises contacting a tetraalkylonium halide with a metal perfluoroalkyl sulfonate to produce a mixture; allowing the second mixture to produce an aqueous upper layer and a separate lower liquid layer; separating the lower liquid layer from the upper aqueous layers to produce a product layer; optionally washing the product layer with 1 to 10 volumes of water, based on the volume of the product layer at a temperature of about 50° C. to about 100° C. to produce a washed product layer; and drying the product layer or washed product.

Abstract: Polyether glycols, especially poly(tetramethylene ether) glycol (PTMEG) having a narrow molecular weight distribution of about 1.25 to 1.80, or dispersity of 1.05 to 1.90, are made by a process involving distilling the low molecular weight fraction in unit operations including at least one short-path distillation evaporator. Two short-path distillation evaporators, in series, are desirable if significant narrowing of the PTMEG is required. In these units, PTMEG is subjected to temperatures in the range of 270.degree.-400.degree. C. with the hold-up time varying between 10-200 seconds. The required vacuum to force the separation of the low molecular weight PTMEG varies between 0.001 mm and 1.0 mbar. PTMEG residue from the distillation unit is also characterized by its low water content and low concentration of oligomeric cyclic ethers.
