Abstract: ELEVATOR SYSTEM            ABSTRACT OF THE DISCLOSURE       A new and improved elevator system, and method of directing a plurality of elevator cars to serve floor calls in an elevator system.  Service is provided for floor calls which cannot be allocated to a suitably conditioned car already busy serving calls, by specifically assigning non-busy or available cars to serve such calls.  The floor calls are each timed from registration and when their registration time reaches a first value the strategy for assigning avail-able cars to non allocated calls is changed.  The timing of a call continues following the reaching of the first value, until the call reaches a second timed value. The strategy for assigning available cars to non-allocated calls is changed again, in response to a call registered for the second predetermined period of time.

Abstract: GROUND FAULT INTERRUPTER MODULE                  Abstract of the Disclosure The module is composed of the internal electronic circuitry and components of a ground fault circuit interrupter, and is designed for use with a power supply system having a neutral conductor and at least one line conductor and carry-ing current between a source and a load, with the neutral conductor being grounded at the source and the supply system including a system circuit interrupter or circuit breaker operable responsive to application of a potential to an operating element such as a solenoid.  The module includes first and second current transformers embracing the neutral conductor and at least one line conductor of the power supply system.  A resistor is connected across the terminals of the secondary winding of the first current transformer so that a potential appears across the resistor responsive to inequality of the currents carried by the neutral and line conductors, as a result of a ground fault.  An operational amplifier has its input connected across the resistor and a feedback network is connected between the input and output of the amplifier to control the gain thereof.  The output of the amplifier is connected to the base of a transistor controlling triggering of an SCR which, when conductive, acts as a switch across terminals connected to the solenoid so as to energize the solenoid to trip the power system circuit breaker.  The secondary winding of the second current transformer is coupled by a capacitor to the output of the amplifier.  When the volt-age across the resistor at the input of the amplifier reaches a predetermined value, responsive to a ground fault, the amplifier output is sufficient to trigger the transistor con-ductive.  If the neutral conductor becomes grounded on the load side of the two current transformers, it forms an ef-fective loop extending through the cores of both current transformers, so that the two current transformers form a magnetic coupling between the output and the input of the amplifier.  The amplifier then breaks into high frequency oscillation and the high frequency signal on the transistor triggers the same conductive to trigger the SCR conductive.          Thus, only one electric circuit performs both basic functions of a ground fault circuit interrupter with a corresponding substantial reduction in components and increase in relia-bility and economy of operation.

Abstract: ABSTRACT OF THE DISCLOSURE      Iron-bearing zinc sulfide concentrates are leached with a sulfuric acid solution containing hexavalent chromium ions, e.g. chromic acid or a dichromate.   The leach solution after separation from undissolved residue is hydrolyzed by heating under pressure at a temperature near or above the boiling point of the solution (ordinarily a range of from about 90°C to about 250°C ) to precipitate iron as a basic ferric salt. The iron precipitate is separated, the residual solution  subjected to zinc dust purification, and the thus purified solution then subjected to a first bifluid electrolysis to electrowin zinc and to regenerate sulfuric acid and reoxidize trivalent chromium ions to hexavalent form. Anolyte discharged from the first electrolysis is subjected as anolyte in a second bifluid electrolysis to oxidize the remaining trivalent chromium to hexavalent form, and thereafter the solution is recycled to the leaching operation.

Abstract: Abstract of the Disclosure In electrical connectors for use in a hostile environment it is usually important to exclude the ambient fluid from the region of the conductors and terminals where these are exposed within the connector.  This exclusion is difficult to achieve satisfactorily in connectors which are to be submerged in water because the hydrostatic pressure urges water into the connector by way of leakage paths that inevitably exist between the mating parts of the connector and at glands where the insulated conductors enter each part of the connector.  A connector for joining electrical conductors is disclosed, comprising separable mating first and second body parts res-pectively having co-operative plug and socket terminals, the body parts when united together defining a closed cavity housing the terminals and a container for pressurised insulant, and means effective to release the pressurised insulant from said container into said cavity after mating of the body parts and closure of the cavity.  The insulant may be a fluid such as air or oil, or it may be a semi-solid or pasty material such as a plastic mastic.  Convenient-ly, the container is a capsule housed in a recess in one body part of the connector and the means to release the pressurised insulant can be a pointed cutter affixed to the other body part of the connector so as to pierce the capsule when the two body parts of the connector are mated.

Abstract: METHOD FOR COATING PARTS      Abstract of the Disclosure.  A method for coating the faces only of parts having faces and backs, includes assembling the parts so that the faces and backs thereof define two opposed coating surfaces.  The parts may be staggered, and alternate parts have their faces disposed in opposite directions, with the faces recessed with respect to the backs of the adjacent parts.  Both coating surfaces therefore comprise a plurality of recessed part faces interspersed with part backs.    A hardenable coating such as a molten hard facing material is applied to both of the coating surfaces and allowed to harden.  After hardening, the surfaces are ground to reduce the thickness of the hardened coating sufficiently to expose the part backs, leaving a desired residual layer of coating adhered to the recessed part faces.  The parts are then disassembled to provide a plurality of separate parts, each having a coating on the face thereof.
