Title: Prophylactic pacemaker
Inventor: CITRON PAUL
IPC: A61N1/365
Filed: 1976-05-14
Granted: 1979-12-11
Abstract: ABSTRACT OF THE DISCLOSURE       A demand pacemaker having different standby and pacing rates and circuitry for selectively rendering the standby and pacing rates substantially identical.  First and second capacitor control the standby and pacing rates, respectively, one capacitor being responsive to either a natural heartbeat or a pacemaker output pulse to alter the rate established by the other.  In a preferred embodiment, the second capacitor is charged during a pacemaker output pulse and discharges through the first capacitor to decrease its charging time, the charging time of the first capacitor controlling the pacemaker output pulse frequency.  Circuitry responsive to externally generated signals causes the second capacitor to charge during both a natural heartbeat or a pacemaker out-put pulse to render the pacemaker standby and pacing rates substantially iden-tical.  In this manner, the pacemaker of the present invention may be employed to monitor heart activity at a first, or standby, rate while providing a pacing function at a second, higher rate, on demand, until such time as the necessity for the pacing function is established with the standby rate then being mod-ified to conform to the pacing rate.

Abstract: METHODS AND MECHANISMS FOR DRILLING TRANSVERSELY                    IN A WELL                 ABSTRACT OF THE INVENTION  Two methods and four mechanisms are disclosed for drilling at right angles to a vertical well at and location or depth in the well.  The drilling mechanisms each comprises a flexible spring biased telescopic fluid conduit having a turbodrill on the lower end thereof for extending from an open-ing in the side of an elongated cylindrical hous-ing for drilling at right angles to the well.  The flexible spring biased telescopic fluid conduit comprises a plurality of axially aligned spools with cylinders interconnecting the adjacent ends of adjacent spools and with a compression spring in each cylinder between the two adjacent spool ends for permitting flexibility and telescopic action of the fluid conduit while resisting high compression and torque loads.  Rubber-like rings and serrations increase the friction between the telescopic spools and cylinders, and tongue-and-groove splines between the flexible spring biased telescopic fluid conduit and the elongated cylin-drical housing increase friction for receiving torque loads in the right angled drilling mechanism. A method for drilling in a transverse direction from a vertical well and a method for forming and assembling a drilling mechanism for drilling at right angles to a vertical well in a well are disclosed.

Abstract: Abstract of the Disclosure A motor-driven propeller is disposed within a draft tube beneath a buoyant float and is adapted to pump water upwardly through the draft tube. In one mode of operation, the pumping device functions as an aerator in that the water pumped upwardly through the draft tube flows upwardly through an opening in the float and is deflected across the upper side of the float and into the atmosphere by a diffuser plate spaced above the opening. The pumping device can be converted into a flow developer by positioning the diffuser plate beneath the opening in the float and, when the plate is so positioned, water pumped upwardly through the draft tube strikes the plate and is deflected outwardly beneath the lower side of the float.

Abstract: ABSTRACT OF THE DISCLOSURE         An ion exchange compound in a fluid organic carrier is cycled between mixing and separating from a weak acid stream and a strong acid stream.  The weak acid stream is cycled between directly contacting ore to chemically dissolve metal and exchanging the metal for hydrogen ions of the exchange compound. The strong acid stream is cycled between exchanging its hydrogen ions for the metal bonded to the exchange compound and yielding the metal to a recovery system.  The mixing and separation of the organic carrier with the two acid streams is by a pump, an electric field and a centrifuge.
