Abstract: A medical electrode for attachment to the skin of a patient has a cup member forming a cavity for containing an electroylyte. The cup member has a base portion which is movable inwardly of the cup member so as to contract the interior volume of the cavity and in so doing displace the electrolyte outwardly of the cup member for contact to the skin of a patient. In a modification, the configuration of the base of the cup member allows an electrode conductor to be supported out of contact with the electrolyte until the base portion is moved to displace electrolyte outwardly of the cup member.

Abstract: In the present invention, an automatic flue damper located in the vent stack of a household furnace or other apparatus requiring venting is interfaced with a thermostatic control and a fuel supply valve associated with the apparatus so as to maintain a vent passage to the atmosphere normally open during times when combustion is occurring in the apparatus and to close the vent passage at an appropriate time following the termination of combustion in the apparatus. The normally open vent condition is maintained by a damper positioning spring. Vent closure following combustion is accomplished by means of a direct current solenoid. Further included in the interfacing circuitry are a temperature sensing device effective to disable the solenoid, thus opening the vent, upon the appearance of unsafe stack temperatures and a pressure sensor which also disables the solenoid to open the vent stack upon the occurrence of an inappropriate discharge of fuel to the combustion chamber.

Abstract: An electrical socket and associated circuitry is provided wherein current can flow to the socket only when a load device is in the socket and a normally open, momentary "make" switch is closed. The circuitry includes a relay for actuating a switch in parallel with the momentary make switch, which relay is energized upon closure of the momentary make switch and remains energized so that current will continue to flow to the socket until a normally closed, momentary "break" switch is opened. Current cannot flow through the socket with the load device removed even if one should touch the socket except in the unlikely event the make switch is closed.Several embodiments are disclosed wherein no current can flow through the socket unless at least three socket parts are engaged. In one form of socket, the socket base contact is divided into two parts, both of which must be engaged in order for the relay to remain energized.

Abstract: A sludge digester is equipped with a network of pipes leading to several separate effluent ports distributed around the base of the digester near its walls. During use, sludge undergoing active digestion within the digester is withdrawn from the digester and forcefully pumped through at least one of said pipes to flush or sweep material tending to settle from less active regions of the digester into other regions undergoing active digestion, thus to prevent accumulations of sludge which is not actively consumed by bacteria.

Abstract: Means are disclosed for introducing a biological poison to water being removed from a lake or stream for presentation to an automatically operating water quality monitoring system. The poison introducing means is operative at only periodic intervals; and, when operating to introduce poison, a sampling device of the monitoring system is disabled to preserve its accuracy. The monitoring system is otherwise permitted to operate routinely during the time the poison is present in the system. The poison is admixed to the water promptly as the water is introduced to the monitoring system, with the result that the biological poison will cleanse the entire monitoring system by killing biological slime otherwise adhering to the exposed surfaces within the system. The biological poison also maintains sensor sensitivity within the monitoring system.

Abstract: A transfer mechanism for transferring armature forms between a supply pallet and an armature winding machine comprises a turret plate rotatable through 180.degree. angles for presenting opposite margins thereof successively to said supply pallet and said winding machine. In operation, the supply pallet is indexed to receive wound armature forms held by a first armature gripping mechanism mounted on said turret plate and to supply unwound armature forms to said first gripping mechanism. As these events occur, the turret plate supports a second armature gripping mechanism which presents unwound armature forms to the winding machine. The winding machine has winding guide members cooperating with semicircular spaces located in a post projecting upwardly from a mounting plate supporting the turret plate to support the unwound armature forms in position for the winding of coils thereon.

Abstract: A container and closure assembly wherein the container is adapted to be initially closed by a sealing means such as a vacuum disc. The closure has two positions of attachment to a bead encircling the container. In the first position of attachment, which accommodates the aforementioned sealing means, the container bead is engaged in an annular notch located in the inside wall of a closure skirt. The notch weakens the skirt so as to allow a distal end of the skirt to be torn from a remaining portion of the closure to free the remaining portion of the closure from attachment to the container bead. This exposes the sealing means so as to allow a removal thereof and access to the contents of the container. The remaining portion of the closure is then reattachable to the container bead at a second position of attachment rendered accessible by removal of the sealing means for reclosure of the container. In a first embodiment, the closure has retention ribs permitting preassembly of the sealing means to the closure.
