Abstract: INVENTORS:  HERMANN GAHWILER and HANSJORG SCHLAEPFER    INVENTION:  DIRECT INDICATOR DEVICE FOR DETERMINING             THE CARDIAC OUTPUT FLOW RATE ACCORDING TO THE THERMODILUTION METHOD     ABSTRACT OF THE DISCLOSURE           A direct indicator device for determining the cardiac output according to the thermodilution method em-bodying two temperature sensors connected to the blood cir-culation for respectively determining the inlet- and dilution temperatures.  A clock generator and a scaler connected at the output of the clock generator are provided, the scaler forming a control signal.  A respective one of the sensors is connected in circuit with inputs of an associated temper-ature-pulse frequency converter, the outputs of which are connected with a respective input of a multiplexer.  A control input of the multiplexer connected with the output of the scaler serves for the alternate switching-through of a signal from one input and from the other input of the multiplexer to the output thereof in time-dependent function of the con-trol signal.  A gate circuit has one input connected with the output of the multiplexer, another input connected with the output of the clock generator and a further input connected with the output of the scaler.  The gate circuit has an output at which there appears the clock rate of the clock generator as a function of time on the one hand of the control signal and on the other hand of the signal at the output of the multiplexer, the output of the gate circuit being connected with the input of a counter.  The output of the counter is connected with the input of an intermediate storage, and a control input of the counter and a control input of the inter-mediate storage are connected at the output of the scaler for the summation of the clock repetition rate delivered to the counter and for the storage thereof as a function of time of the control signal.  A digital computer has connected therewith a digital indicator device, the computer having in-puts connected respectively with the output of the intermediate storage, the output of the clock generator and the output of the scaler.                             - 1a -

Abstract: ABSTRACT OF THE DISCLOSURE           A gas cooking range of the smooth top type has four burners positioned under a single plate of heat-resistant glass/ceramic material; and a single igniter and safety control assembly is centrally positioned between the burners. The supply of gas to each of the burners-flows through an ignition chamber where it is ignited, and it then flows through a combustion tube to a combustion chamber, where combustion is completed.  Some air is mixed with the gas at the fuel supply control valve, and additional air is supplied through the ignition chamber.  The burning gas mixture then flows through the combustion tube to the combustion chamber at the entrance of which an additional quantity of air is added to provide the remainder of air necessary for complete combustion.  Air is drawn into the system, and the products of combustion are exhausted  by a blower positioned at the lower rear of the range so that a negative pressure condition is maintained along the entire path of flow of the fuel gas from the control valve and through the combustion chamber.

Abstract: Abstract of the Disclosure A cleaning composition of high chemical activity with anti-fungal properties, and with low dry weight residue and particularly useful for cleaning the surface of phono-graph records; the mixture includes a surfactant, an emul-sifier, an anti-microbe or fungicide, all intermixed in a liquid carrier such as water.  This composition is most effective when used in combination with a brush designed having a cloth cover whose projecting filament form a pile that is finished and maintained angularly, and which when brushed against this pile effectively loosens dirt par-ticles from the phonograph record surfaces being treated.          In the method of use of this invention, the cleaning composition may be applied to the leading edge of said brush pile, with the brush then being moved simultaneously across and with a rolling action upon the surface being cleaned, as for example, the phonograph record surfaces, thereby effectively cleaning the disc of lipids, dust particles, and fungal particles that may clog and/or be ger-minating in the microgrooves of the same.

Abstract: ABSTRACT OF THE DISCLOSURE                 A transformerless hybrid for coupling signals between two wire and four wire transmission circuits, and capable of meeting the operating requirements of practical telephone systems. The hybrid includes a pair of terminating impedances serially connected between the two wire port and the circuitry driving that port, the impedances being precisely matched and coupled to a.c. ground, thereby providing a hybrid with excellent longitudinal balance. Amplifiers driving the two wire port through the terminating impedance may be biased to couple a d.c. potential to the two wire line whereby the terminating impedances serve as battery feed resistors. Reverse signal recovery is provided by an amplifier differentially connected to the two wire port, achieving excellent longitudinal rejection and further allowing the amplifier to serve a supervisory function. Two of such hybrids, connected back to back, with amplification interposed therebetween, form an improved transformer-less repeater. In this embodiment, the amplifier may be constructed to be of variable gain, with the gain automatically adjusted as a function of sensed loop current, whereby the repeater may be installed without manually adjusting the amplification to suit the loop length.

The fastening assembly includes an elongated fastener which is driven into the supporting surface with the head end of the fastener protruding from the supporting surface a distance approximately equal to the thickness of the batt of insulation.  The batt is then impaled upon the protruding fastener and pushed down thereon until the head of the fastener protrudes from the surface of the batt remote from the supporting surface.  A planar locking clip having a keyhole-shaped opening is then slipped over the fastener head and wedged between the fastener head and the batt.  The locking clip is held in place by engagement with the fastener head, and prevents the insulation batt from pulling away from the supporting surface.

Abstract: IMPROVED FERRORESONANT VOLTAGE REGULATING CIRCUIT     Abstract of the Disclosure:           A ferroresonant voltage regulator circuit includes a non-saturating transformer, a linear reactor in series with the input, and a capacitor across the non-saturating transformer.          Voltage sensing and referencing circuits are inserted in the output.  A synchronous switch  -- usually a saturable reactor, a magnetic amplifier, a triac or back-to-back SCR's  --  is connected in shunt across at least a portion of the non-saturating transformer, and is controlled by its control coil in a manner such that the non-saturating transformer is loaded by the shunt loop at no-load conditions of the regulator.  The control coil of the synchronous switch is connected in the voltage sensing and referencing circuits, and acts so that the amount of loading on the non-saturating transformer from the synchronous switch varies substantially inversely as the amount of loading because of the load on the voltage regulator circuit.  A linear reactor may be series connected with the synchronous switch in the shunt loop.  The non-saturating transformer has an air gap in its iron core so that it has a considerably more linear volt-ampere vs. flux density characteristic of the core and air gap than that of a similarly rated and constructed saturating transformer.
