Abstract: TITLE          Coupling Clutch/Brake And Housing ABSTRACT OF THE DISCLOSURE    A coupling clutch/brake according to the teachings of the present invention is shown in its most preferred form as including first and second hubs having first and second splined friction discs received thereon.  The first friction disc is movable between the second friction disc and a stationary friction surface mounted to a housing by a piston reciprocally mounted to the housing and rotatably mounted to the first friction disc by a bearing mounted therebetween.  The second friction disc is substantially prevented from sliding on the splines with the second hub.  The splines between the second friction disc and the second hub allow the second friction disc to cant to compensate for axial angular misalignment of the first and second hubs.  In its most preferred form, the housing has a unique construction and specifically includes three generally hemispherical components.  The open ends of the first and second shells abut together to form a volume for the first and second friction discs.  The open end of the third shell is received on an axially extending flange integral with the second shell.  The piston is slidably received on the flange of the second shell and on the third shell.

Abstract: ABSTRACT     An insert for use in a modified cyclone apparatus, which surrounds the vapour outlet conduit thereof.  Such insert lessens the tendency for carbonaceous deposits to form within the cyclone apparatus when separating mixtures of particulate and conversion products from high Conradson carbon feedstocks, by narrowing the space between the outside surface of vapour outlet conduit of the cyclone apparatus and the interior circumferential  wall surrounding the outlet tube.  In a particular embodiment, this is achieved by locating the insert around at least a portion of the vapour outlet conduit in a way preferably not centrosymmetric with respect to the longitudinal axis of the cyclone apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE            An object is produced from a tubular blank of thermo-plastic material of the type polyester or polyamide, preferably of polyethylene terephthalate by reducing the thickness of amorphous material in one or several areas of the blank by means of one single or several consecutive re-shaping operations.  A mechanical shaping device moves a transitional zone situated between thicker and thinner material along the blank and elongates simul-taneously the blank in the moving direction of the tran-sitional zone.  After the last re-shaping operation the thinner material has preferably an oriented state.  During the re-shaping operation the temperature of the material in the transitional zone is controlled at a level which, immediately before the re-shaping operation, is within or close to the range of the glass transition temperature. In one embodiment the reduction of the wall thickness of the material is begun in a track in the wall of the blank and continues symmetrically around the track. Clamping devices are used to maintain the axial position of the blank.  The blank is suitable for re-shaping for instance into a container in which the mouth too consists of oriented material.  The invention offers possibilities for materials savings by comparison with previously used methods, at the same time as the thermal and mechanical characteristics of the container are improved.

Abstract: ABSTRACT         A method of producing alkaline peroxide, and a solution for use therein, comprising electrolyzing an alkaline solution in the presence of oxygen, in an electrochemical cell.  The solution used contains a transition metal ion complexing agent which may be ineffective in complexing transition metal ions in the strongly alkaline solutions used.  Such method inhibits reduction in current efficiency of the electrochemical cell during long term operation.  In addition, the method may be advantageously used to increase current efficiency in an electrochemical cell previously used for producing alkaline peroxide with a solution which did not contain a metal ion complexing agent, and which cell is suffering from substantially reduced current efficiency.          The pH of the solutions used is typically greater than or equal to about 13.

Abstract: A B S T R A C T           An improved refractory inductor block is provided for channel induction furnaces for melting aluminum com-prising a hearth and an inductor.  The improvement comprises casting the refractory inductor block from a refractory resistant to corrosion by molten aluminum comprising 9.5 to 40 wt.% calcium aluminate, 0.5 to 10 wt.% of a borosilicate frit, and 60 to 90 wt.% of an aggregate consisting of an alumina-bearing compound, a silica-bearing compound or mixtures thereof.  The refractory is cast around a solid core pattern made from a material capable of desolidifying upon the application of heat, such as a wax pattern.  The channel core pattern is shaped to provide the desired channels within the refractory inductor block.  After formation of the green refractory, the mold material, such as wax, may be melted off and the refractory cured by firing at a temperature of from 760 to 871°C.
