Abstract: BLOOD OXYGENATION            Abstract of the Disclosure A rigid blood oxygenator in which blood and oxygen-rich gas are admitted at the top of the device and caused to flow substantially concurrently downwardly through a tortuous path.  During the course of this downward flow, oxygen-rich gas bubbles are formed in the blood and a gas transfer is accomplished according to which the oxygen content of the blood is enriched and carbon dioxide is removed from the blood, which gas transfer is enhanced by the secondary flow induced by the tortuous path.  During the course of downward flow, the blood-gas-bubble mixture is also passed around a heat exchange device, which preferably is convoluted so as to form a tortuous path, to bring the blood to a desired temperature.  The device is equipped with a defoaming means such that the blood bubbles are converted back into liquid blood, which is then returned to the patient.  Vent means are provided for removal of carbon dioxide and other vent gases.  Means for promoting secondary flow in the blood are preferably pro-vided in the upward region of the oxygenator.  The present invention also comprehends the method of transferring gas in which the flow path of the blood-gas mixture during oxygenation is in a substantially downward direction and is tortuous, as well as simultaneous causing heat exchange to occur.

Abstract: OPERATING MECHANISM FOR A CIRCUIT INTERRUPTING DEVICE           ABSTRACT:  A bus-mountable, circuit-interrupting device, including an interrupting unit and a novel line-potential, manually-resettable operating mechanism for the unit, is usable in circuits in which faults may exceed the interrupting capability of the unit.  A normally engaged pair of contacts in the unit is separable within an arc-extinguishing medium.  The operating mechanism includes a robust, stored-energy operator, for separating the con-tacts, and a tripping mechanism, which selectively releases the stored operating energy.  The tripping mechanism nor-mally prevents release of the stored operating energy, and includes a high mechanical advantage lever-link system which permits a low latching force to counteract the stored operating energy.  A ratchet-solenoid combination in the tripping mechanism selectively removes the low latching force.  If a circuit fault occurs, the solenoid moves an arm past, and moves, the ratchet in a first direction, which does not remove the low latching force, but rather stores energy capable of moving the arm in a second direc-tion.  Arm movement in the second direction, which occurs immediately in the case of a fault within the interrupting capability of the interrupting unit, moves the ratchet so as to remove the low latching force, permitting the stored operating energy to overcome the latch and move the lever-link system, thereby separating the contacts.  If the fault exceeds the interrupting capability of the unit, the arm moves in the first direction, but is prevented from moving in the second direction until the circuit is otherwise opened, as by an upstream protective device.

Abstract: ABSTRACT   The invention describes a process which permits (1) the preparation of polymer solutions of sulfonated polymers in organic liquid having reasonably low viscosities (i.e., less than 20,000 cps), (2) the preparation of extremely viscous solutions or gels from such solutions by the simple process of mixing water with the polymer solution and (3) the reversion of such viscous solutions or gels to relatively low viscosity mixtures ? the reincorporation of polar cosolvents which are water immiscible at a desired stage.  These operations are achieved by the use of the appropriate concentration of polymers having low concentrations of ionic groups present, preferably metal sulfonate groups.  The novel process forms a polymeric solution or gel having a viscosity of at lease 50,000 cps and includes the steps of (a) forming a solvent system of an organic liquid and a polar cosolvent, the polar cosolvent being less than about 15 wt. % and the viscosity of the solution system being less than about 1,000 cps (b) dissolving a neutralized sulfonated polymer in the solvent system to form a solution, the concentration of the neutralized sulfonated polymer in the solution being 0.1 to 20 wt %, and the viscosity of the solution being less than 20,000 cps, and (c) adding 5 to 500 volume % water to the solution, the water being immiscible with the solution, with the polar cosolvent transferring from the solution to the water causing the viscosity of the solution or suspension to increase from less than 20,000 cps to greater than 50,000 cps.

Abstract: ABSTRACT         A digital control unit has an oscillator driven, binary coded counter, the outputs of which are connected to the first addend inputs of a number of adders.  The second addend inputs of the adders are connected to phase angle inputs.  The summation outputs of the adders are connected to a logic circuit, which derives timing pulses from the signals at the summation outputs of the adders and interlinks them to form a three-phase system of firing pulses for the controlled valves of the converter.  The control unit can be used for fast shutdown of the controlled converter by blocking the firing pulses for the controlled main valves and shifting the firing pulses for the quenching valves as a function of the instantaneous phase of the converter output voltage; also the operating frequency can be increased.

Abstract: VISION THERAPEUTIC APPARATUS Abstract of the Disclosure Vision therapeutic apparatus comprising spaced apart displays for showing sequences of images to a viewer-patient.  The apparatus provides the capability to vary the rate of image display and keeps score of the occurrence of the special events and the detections or misses thereof by the viewer.  In one embodiment, two displays (10, 12) are disposed, generally, in line, one near to and the other distant from the viewer.  Each display shows, on a random basis, a series of different images which alternate, image to image, with the series of images shown by the other display.  The viewer alternately observes the near and distant displays, thereby performing an optical exercise, and signals to the apparatus when a special visual event occurs, e.g., the successive showing of the same image by the two dis-plays.  In another embodiment, two displays (20, 22) are spaced in side by side relation and are simultaneously observable by the viewer.  The displays show images at the same time, and a special visual event occurs when the two side by side images, when converged by the eyes of the viewer (this being the optical exercise), form a composite, single image recognizable by the viewer. The spacing of the side by side displays is variable.

Abstract: ABSTRACT OF THE DISCLOSURE          An oil burner primary control in an interrupted ignition burner control system includes a miniature coupling transformer for controlling operation of the igniter.  The gate circuit of a flame responsive switch is effective, in the absence of a burner flame, to generate a plurality of gating pulses at a frequency substantially greater than line frequency.  The flame responsive switch is cyclically gated on by the pulses for energizing a safety switch resistance heater.  The primary winding of the coupling transformer is connected in the gate circuit of the flame responsive switch and is responsive to the gating pulses to induce voltage pulses in its secondary winding which is con-nected in the gate circuit of an ignition switch controlling the igniter.  At least one of the pulses occurs sufficiently early in each half cycle of the sine wave alternating current appearing at the ignition switch so that the ignition switch conducts during essentially all of the sine wave, as long as there is no burner flame.  When burner flame appears, the pulses are terminated, de-energizing the safety switch resistance heater and the igniter.
