Abstract: Abstract of the Disclosure A gas heated soldering iron comprises a soldering head having a chamber into which a gas/air mixture is fed by means of a bunsen tube to burn as a small, very hot flame.  The chamber is surrounded by a flame suppression gauze which protects the flame and prevents any combustible gases outside the chamber being ignited.  Gas is supplied to the bunsen tube from a fine jet to which the gas is fed at low pressure.  The low pressure is regulated by a valve operating  mechanism which cooperates with the depressible valve of a disposable gas canister to form a differential valve.   The canister serves as a handle for the soldering iron, and is insulated from the soldering head.   1(a)                    Cont. 2

Abstract: EXCESS CONSUMPTION WATTHOUR METER                     ABSTRACT    A restraining means of mildly magnetic material is adjustably implanted in the rotor disc of a conven-tional watthour meter,  The restraining means interacts with a magnetic field generated by the meter's damping magnet to stop the disc from turning when the rate of energy consumption in the metered circuit is below a predetermined rate.  The predetermined rate can be alter-ed by varying the radial distance between the center of the disc and the restraining means and by varying the amount of magnetic material passing through the field of the damping magnet.

Abstract: ABSTRACT OF THE DISCLOSURE A tape playback unit is designed to transmit messages recorded on an endless loop dual channel recording tape.  The tape contains a series of independent messages recorded on one channel and stop-start signals coordinated with the beginning and end of each message on the other channel. A multiple of receiving units each having an audio receiver as in a tele-phone receiver, hereafter referred to as an earphone, are connected to said playback unit and the independent messages contained on the tape are trans-mitted to the earphones.  A control unit associated with each receiving unit intercepts the message being transmitted by the playback unit and permits transmitting thereof to the earphone only upon activation of a switch associated with the receiving unit, e.g. activated by a coin.  The control unit further includes a timer associated with detecting means for detecting the beginning and end of each message, i.e. it detects the stop-start signals on said other channel.  The earphone receives transmission only after the switch is activated and the start of a sentence is detected and ends only after the timer signals completion of the timing cycle and the end of a sentence is detected.

Abstract: 45,781 DISTRIBUTION TRANSFORMER SECONDARY CIRCUIT   INTERRUPTER HAVING AN IMPROVED BIMETAL     ABSTRACT OF THE DISCLOSURE         A distribution transformer having a secondary circuit breaker utilizing a bimetal thermal trip for opening the circuit breaker upon the occurrence of overload currents wherein the power dissipation is concentrated in the base of the bimetal.  The teachings of this invention are particu-larly adaptable for an oil immersed circuit breaker, as utilized with distribution transformers wherein a given oil temperature change must produce a required deflection and a given current flow for a predetermined period of time must also produce the required deflection,  Standard bimetal thermal trip elements are generally constructed with a linear power distribution along their lengths to provide a predetermined deflection,  The total power dissipation in the bimetal can be reduced and the predetermined deflection still obtained by concentrating the power dissipation in the base of the bimetal trip element,  A movable bridging contact is spring biased towards an open position separated from the stationary contact, but with the circuit breaker in the normally closed position is held in engagement with the stationary contact. by a latching mechanism which is respon-sive to a bimetal trip element to allow the circuit breaker to trip open during selected overloads,  The conducting bridging contact completes a series circuit through the circuit breaker which opens during circuit interruption, The secondary circuit breaker can also, if desired, be provided with a signal light circuit which activates the signal light, on the exterior housing of the transformer, when current through the circuit breaker exceeds a low signal overload value which is less than the trip value.  A single signal light provided for each multipole circuit breaker can be activated by the bimetals of any one of the individual poles.
