Patent CA-1067453-A (CA)
Inventor: CASSON HAROLD V
IPC: C25B1/26
Filed: 1976-05-03
Granted: 1979-12-04
Abstract: ABSTRACT         An electrolytic cell is provided that is particularly suitable for the production of oxy-halogen compounds such as sodium chlorate by electrolysis of an alkali metal halide such as sodium chloride.   A cell chamber is provided containing an electrode assembly and is connected for the circulation of electrolytic solution to a cooling and concentrating chamber.          Gas communication between the cell chamber and the cooling and concentration chamber is substantially avoided.  Gas evolved during the electrolysis is separately removed from the cell chamber and is preferably scrubbed.  Gas such as air is swept through the cooling and concentration chamber so as to provide at least part of the cooling requirements for removing the heat generated during the electrolysis and to evaporate, thereby concentrating the electrolytic solution.   This takes advantage of the sensible heat of the electrolytic solution for the evaporation of such solution.

Granted: 1979-02-06
Abstract: Abstract of the Disclosure A thermal barrier member or shape of plastic or other suitable insulating material having a plurality of small flat-faced surface protrusions or projections thereon located at selected areas on the member is provided for joining metal members of a window or door frame together.  End portions of the projections are adapted to be shaved off or sheared to form the flat faces when the thermal barrier member is joined to the metal members.  The insulating member is slidably longitudinally joined to the metal members.  The receiving metal members are adapted to receive the thermal barrier member and the receiving areas are of such a size that the end portions of the small projections on the thermal barrier member are shaved off in the joining process.  Such construction provides a tight or interference fit between the metal members and the thermal barrier member thereby providing a unitary thermo break or thermal barrier construction.  Greater dimensional variations in either the insulating member or the metal members are permissable with the invention.

Abstract: ABSTRACT OF THE DISCLOSURE      Electrical circuitry for delivering to a flashtube a series of flash-producing electrical pulses. The circuitry includes energy circuitry for repeatedly storing electrical energy and discharging the energy in the form of such pulses through the flashtube, each pulse producing a flash, each flash being grouped in a flash cycle synchronized with a cycle of an AC voltage source. The energy circuitry comprises first and second capacitors connected by a switching element responsive to the difference between a first voltage at the junction between the first capacitor and the switching element and a second voltage on the second capacitor. The energy circuitry steps up the voltage discharged across the flashtube by the second capacitor. Firing circuitry is provided for receiving during each flash cycle a portion of the energy discharged by the energy circuitry, to initiate each flash. The firing circuitry is timed to initiate the flash, thereby reducing the second voltage upon discharge of the second capacitor, at a time during the period when the first voltage is below the value of the extinction voltage of the flashtube. Thus the switching element remains off during the flash and the flashtube is thereby isolated from the first capacitor during the flash.

Abstract: ABSTRACT OF THE DISCLOSURE               A resiliently impact cushioned adhesive-applied restricted growth low profile wall surfacing system for use in sports activities is provided.  The wooden or composition wall members are held in place by spaced ridged elastomeric cushioning adhesive material between the wall members and the receiving sur-face.

Abstract: Improvement in the mass transfer in liquid media Abstract of the disclosure:    In the case of reactions in the liquid phase the reactants should be contacted with one another as intimately as possible.  The economy of a process depends on the transfer of the reactants to the place were the reaction takes place and the removal of the reaction product. The mass transfer in liquid media can be improved by adding to the liquid medium 0.1 to 10 % by volume of inert solid particles having a specific gravity which is by 1.1 to 20 times greater than that of the liquid medium and imparting to the liquid medium a movement such that the solid particles having a diamter of from 0.1 to 40 mm are kept in suspension.

Control of the agglomerate size dis-tribusion discharged from the drum is achieved by increasing the relative residence time of the small or growing agglomerates and by limiting contact between the large formed agglomerates and the small forming or growing agglomerates.  The preferred means to insure adequate growth time for the small agglomerates consists of a plurality of annular ribs spaced about the inside wall of the drum and a cooperative scraping mechanism.          The scraping mechanism comprises a plurality of scraper blades projecting radially from a rotating shaft throughout the length thereof of the agglomerate-forming section of the drum.  However, at the annular paths wherein a rib is found the scraping blades are shorter in length.

Abstract: MARINE PROPULSION CONTROL SYSTEM       WITH MANEUVERING BRAKE                      Abstract of the Disclosure There is disclosed an improved control system for air actuated ahead and astern clutches, an engine speed governor, and a propeller shaft brake of a marine pro-pulsion system. The control is actuated by a throttle lever which is moved from a neutral position to select a direction of travel. The degree of movement from neutral of the throttle lever is representative of the desired speed in the selected direction. The improved control engages the brake when the throttle lever is in neutral and when the throttle lever is moved from an ahead to an astern direction at medium or high forward speeds. When such a change in commanded direction occurs, a shift delay valve is first actuated to delay the inflation of the astern clutch. The delay is dependent upon the for-ward speed previously prevailing. At medium forward speeds the brake is released shortly after the astern clutch begins to inflate. At high forward speeds the brake is released when the pressure within the inflating astern clutch reaches a predetermined level. At low forward speed, the brake will not be engaged. The shift delay valve can be manually overridden to immediately signal for the inflation of the astern clutch.
