Abstract: ABSTRACT OF THE DISCLOSURE         A new "cold" process for the recovery of elemental sulphur from contaminated elemental sulphur products is described.  Elemental sulphur is recovered by froth flotation from:  contaminated base pads of elemental sulphur blocks, stockpiles of contaminated elemental sulphur, contaminated elemental sulphur rejects from industrial handling and hauling, complex sulphur agglomerate, reject by-product from hot melting processes which is presently unprocessable and discarded (or as is otherwise referred to as "sulphur crete melt residue"), contaminated products resulting from the exploitation processes using wells for the application of heat to reservoirs in order to recover elemental sulphur, and also from other sources of contaminated elemental sulphur in the oil and gas and other industries.          This process comprises the steps of coarse screening, crushing, wet grinding, sizing, classifying; then, the wet ground slurry at ambient temperature is treated by froth flotation, removing the elementary sulphur in the froth, and transporting the undesirable contaminants to storage ponds or subsequent land reclamation.  The initial elemental sulphur froth from the first stage of flotation is cleaned one or more times by reflotations.  The cleaned elemental sulphur-bearing froth is then filtered to remove excess water and to produce a filter cake.

Abstract: ABSTRACT OF THE DISCLOSURE     A low-speed diesel engine which is used as the propulsion engine for a passenger ship is directly coupled to a drive shaft bearing a variable-pitch propellor.  The propulsion engine is designed to provide the propulsion power for the required maximal cruising speed.  To provide additional power for reaching peak speed, an electric motor/generator is provided in series with the engine and supplied by the reserve power from the ship's electrical system.  Electrical energy is generated by a number of medium-speed or high-speed four-stroke engines.  Their power is dimensioned so that the ship's electrical system has a high excess of capacity over requirements.

Abstract: ABSTRACT OF THE DISCLOSURE:         An apparatus for driving arches into the ground for the making of a cultivation tunnel comprises a drum-like body made of a pair of wheels interconnected by three transverse arcuate arch supports and rotatably mounted on a chassis.  The ends of the arcuate arch supports are pivoted to the rims of the wheels adjacent the wheel spokes but behind them in the direction of rotation of the wheels.  The arch supports are held within the two wheels and forced to diverge from the spokes by a spring mechanism. Each arch support defines an outwardly open trough into which an arch is inserted, being held in the trough by hooks that are resiliently biassed into captive position of the arch in its support. A cam assembly on each arch support and on the chassis forces the arch support to move toward the vertical against the bias of the spring mechanism as the ends of the arch start to touch the ground.  Further rotation of the wheels drives the arch ends into the ground.  When each support and arch therein stand vertical, bars fixed to the spokes engage the hooks of the support and release them from the support, against their bias, to thus free the arch from its support.

Abstract: Apparatus (10) for the concentration and beneficiation of particulate matter by froth flotation employs a constriction plate (14) which separates vertically arranged flotation (17) and hydraulic (18) compartments. A discharge duct (29) may be used to extend through the hydraulic compartment (18) and to open through the constriction plate (14) centrally thereof. Orifices (16) in the constriction plate (14) are in communication with the hydraulic compartment (18) to provide a uniform dispersion of air bubbles in the flotation compartment (17). Aerated water distribution manifolds (22, 42) within the hydraulic compartment (18) and within the lower portion of the flotation compartment (17) are provided to enter the aerated water into the flotation compartment substantially uniformly throughout a horizontal cross-section thereof. In order to minimize the energy consumption of the apparatus (10) and to provide for the introduction of aerated water at a reduced flow rate, amenable to the separation of aqueous pulps having a low concentration of solid matter by volume, such as sulfides, a stream of pressurized air is passed through an eductor (53) wherein a mixture of water and, if desired, an appropriate surfactant is aspirated into the stream of flowing pressurized air. The flowing stream of pressurized air and the aspirated water and surfactant are then passed through a venturi region (59), producing a highly aerated, low water volume stream of aerated water for delivery to the hydraulic compartment (18).
