Title: Electrical contact for use in a current-interrupting unit
Inventor: HALL WALTER J
IPC: H01H1/44
Filed: 1983-08-09
Granted: 1987-05-19
Abstract: ABSTRACT OF THE DISCLOSURE A female interrupting contact for a current-interrupting unit includes a smoothly contoured, apertured pressure ring which is held in a groove formed in the wall of a bore through a contact body. A spring in the groove maintains the ring to one side of the bore so that the aperture is normally misaligned with the path of a male contact through the bore. When the male contact enters the aperture, it moves the ring against the action of the spring to align the aperture with its path. This alignment effects intimate sliding engagement between the male contact and both the ring and the wall of the bore, one or both of the latter of which are conductive so that a reliable electrical path through the contacts and the interrupting unit is established.

Abstract: A thermal engine with a power source located either externally or internally to its cylinders, such as a compressor or Stirling cycle engine. The engine includes a plurality of chambers in each which a double-effect piston is mounted. Each piston and chamber together form an expansion phase side and a compression phase side. Each expansion side of one piston and chamber assembly communicates via a fluid transfer circuit with a compression side formed by another piston and chamber assembly and directly opposite the expansion side. Each fluid transfer circuit is traversed by a gas conveyed from one chamber to the other by movement of the pistons. Each piston is equipped with an arm cooperating with means for transforming reciprocal circular motion of the pistons into circular motion of an output shaft. The chambers are distributed around the transforming means and the output shaft. Each chamber, piston and each expansion and compression side have a toroidal shape.

Abstract: CURRENT LIMITER FOR TELEPHONE OFFICE SIGNALLING by JOHN M. HUFT                         ABSTRACT OF DISCLOSURE A ring-ground circuit in a telephone system comprises a control transistor that selectively receives base drive from a microprocessor and that has its emitter connected through a low voltage LED and through the series combination of the base-emitter junction of a switching transistor and its emitter resistor to ground.  The LED has a sharp transition in its conduction characteristics when the voltage across it reaches a pre-determined value which is a reference voltage.  Conduction of the control transistor provides base drive to the switching transistor for causing collector current in the latter to initiate a ground-start condition in a relay coil that is connected to a central office battery voltage.  When current in the switching transistor increases to a prescribed value, that is set by the LED reference voltage and the emitter resistor, conduction of the switching transistor is automatically controlled for limiting the maximum value of its collector current.

Abstract: Abstract of the Disclosure Ammoniacal solutions that have been employed as a bath for etching copper such as in the manufacture of printed circuits are reconstituted or regenerated to substantially fully remove excessive copper solute therefrom and retain the ammonia content thereof in such a manner as to enable a continuous reuse of the etching solution.  The process is conducted in such a manner that no contaminating metal powder, compounds or sludge are formed.          The reconditioning is effected by introducing used copper solute containing ammonium etching solution into an electrolytic bath in which cathodic and anodic electrode containing compartments are defined by a cationic permeable membrane therebetween with the cathodic compartment having an electronegative cathode electrode plate therein.  Normal corrosion current generation and flow in the cell is substantially restricted and the copper content of the solution is substantially solely plated out as a pure metal slab on the cathode plate electrode by applying a sufficient external direct current potential to the cell, to thereby negate normal current flow of the cell, deterioration of the cathode, and in such a manner as to prevent formation of copper powder, metal compounds and sludges within the cell from either the cathode metal or the copper solute content of the ammoniacal etching solution.  The operation is conducted in such a manner as to con-serve the ammonia content of the used copper etch solution and enable the reconditioned solution to be reused with a minimized loss of its active etching ingredients.

Abstract: ABSTRACT OF THE INVENTION         A reclosing relay for reclosing a circuit breaker in an electrical power system.  The reclosing relay is a multi-shot reclosing relay (i.e., providing more than one reclosure  command to  the circuit breaker)  and includes primary and redundant lockout circuits for each reclose circuit.  The primary lockout scheme employs a flip-flop, with a reset timer for resetting if the breaker remains closed after the first reclosure.  The flip-flop is set when the circuit breaker recloses to lockout the first reclosure  circuit.  The redundant lockout circuit locks out the first reclosure circuit after a trip, reclose, and retrip  sequence.   The  second  reclose  circuit  includes similar primary and redundant lockout circuits.

ABSTRACT OF THE DISCLOSURE       A dispenser for cleaning and maintaining the cleanliness of a toilet bowl of a flush toilet is provided to co-dispense doses of two or more chemical solutions in response to the change in water level in the toilet tank reservoir during a flush cycle. The dispenser is to have an operational life based on an approximately predetermined number of flush cycles and includes a first internal reservoir containing a quantity of soluble solid-state first chemical sufficient to provide a saturated dose of first chemical cleaning solution in response to each flush cycle throughout the opera-tional life of the dispenser to thereby maintain bowl cleanliness. A second internal reservoir is also provided which contains a quantity of soluble solid-state second chemical sufficient to pro-vide a saturated dose of second chemical cleaning solution in response to each flush cycle only during an initial minor portion of the operational life of the dispenser thereby providing addi-tional concentration of chemicals within the toilet bowl to facilitate loosening of established organic soil deposits on contacting toilet bowl surfaces. Both the first and second internal reservoirs include dispensing passageways for conveying the respective doses of chemical solutions to the water in the toilet tank in response to water level change therewithin during a flush cycle. Both reservoirs also include air vents and means to provide isolation of the respective chemical solutions from the toilet tank reservoir water during quiescent periods.
