Abstract:
A base assembly for a reel, such as a hose reel, including two cooperating base components joined to one another and supporting a spool assembly. The base components may be identical to one another, and each include a base portion and an upright portion disposed 90° with respect to one another and formed monolithically from a single piece of material such as steel. The base components further include rigidifying structures such as gussets, edge bends, and reinforcement ribs or channels to rigidify the base components against vibration and impact stresses. Each of the base portions includes a connection plate and an offset connection flange, wherein the connection flanges overlap and are secured to respective connection plates when the upright components are mated and secured to one another with one upright component disposed at an orientation rotated 180° with respect to the other. The base assembly may be attached to a surface, such as a floor, wall, or other surface via suitable fasteners, and the connections between the upright components are substantially isolated from vibration and impact stresses imposed upon on the base assembly. In one exemplary embodiment, the connection between base components may be varied to provide modularity to the base assembly. In this embodiment, the base assembly may be configured to support spool assemblies of various dimensions.
Abstract:
The present invention provides a hybrid lighting system that comprises at least one light collector for generating an output of fluorescent light. The light collector comprises an optically transmissive material that is doped with dispersed dye molecules which are arranged to absorb incoming solar light and to emit fluorescence light. The hybrid lighting system also comprises at least one electrically powered light emitting device that, in use, supplements the output of the light collector to providing light of a predetermined spectral characteristic.
Abstract:
The invention concerns a process for the preparation of chlorinated derivatives of pyridine compounds by a chlorination reaction of the corresponding pyridine compounds with molecular chlorine, carried out in the gaseous phase by means of bis(trichloromethyl)sulfone as a free radical initiator. The obtained chlorinated derivatives of pyridine compounds, such as 2,6-dichloropyridine, can be used as chemical intermediates.
Abstract:
The liquid phase dehydrochlorination of haloalkanes is performed with an initiator mainly comprising decachlorobutane and/or octachloro-1-butene.The process is applicable, in particular, to the production of chloroethylenes from the corresponding polychloroethanes.
Abstract:
A method of increasing productivity and recovery of wells in oil and gas fields includes determining a direction of maximal horizontal stresses, producing at least two wells so that they are spaced from one another in a direction corresponding to the direction of the maximum horizontal stresses, forming in at least one of the wells at least one vertical slot oriented substantially from the at least one well to the other of the wells, and introducing a hydrofracturing fluid at least into the at least one well to produce a hydraulic fracture in direction from the at least one well to the other well.
Abstract:
The invention relates to side-scattering light guides that generally comprise a core of transparent optically homogenous material seeded with diffuser particles. The light guide also comprises an optically transmitting sheath, having a lowerrefractive index than the core, surrounding and in contact with the sides of the core to prevent any light being transmitted along the core from escaping through the core's sides. In general, the diffuser particles impart only a small deviation to light rays incident upon them, and are distributed to scatter light being transmitted along the core so that at least some of the scattered light exits the sides of the core. A diffusing jacket is arranged to intercept scattered light exiting the sides of the core.
Abstract:
The invention relates to a process for the manufacture of a fluorinated hydrocarbon by the reaction of hydrogen fluoride with an unsaturated chlorinated hydrocarbon in the liquid phase in the presence of a catalyst constituted by a tin compound and of an additive constituted by an organophosphorus compound.
Abstract:
A plurality of nozzles are located on each side of a foot washing station on curved portions of spray members. At least some of the nozzles are located at a plurality of elevations and are downwardly directed to knock debris off the lower leg and foot of a user to thus wash the debris away. A foot platform supports the foot or feet of a user is preferably continuously sloped so that water does not accumulate at any portion of the foot platform. Additionally, an actuator is preferably actuated by the placement of the weight of the foot on the foot platform to begin the spraying of the foot or feet with water in a hands-free operation. Spray nozzle tips are screwed into orifices which then dispense water under pressure preferably in a spray pattern with highly atomized water pellets efficiently removing debris from the feet of a user.
