Abstract: Abstract of the Disclosure A fastener for securing built-up roofing membranes used to water-proof cementitious roof decks combines the conventional nail used for this pur-pose having a head and a shank portion designed to resist withdrawal of the fastener from the dock, with a non-intergral tab penetrated by the shank of the nail and of larger diameter than the nail head, the tab having a design which allows the flued asphalt conventionally poured over the nail during construction of the roofing membrane to bond the portion of the membrane beneath the tab and thereby increase the wind uplift resistance of the cover-ing material.  Removability of the tab allows its detachment in applications where increased uplift resistance is unnecessary.

Abstract: VIR-CONTROLLED HUE CORRECTION CIRCUIT     ABSTRACT OF THE DISCLOSURE     A hue correction circuit for use in video display apparatus which is responsive to a composite color video signal including luminance, chrominance, burst and VIR signals. A controllable local oscillator circuit generates a reference oscillating signal of con-trollable phase for use in demodulating the chrominance signal.          A first phase control circuit is responsive to the burst signal for deriving a first phase control signal as a function of the phase error between the burst signal and the reference oscillating signal, this first phase control signal being applied to the local oscillator circuit to vary the phase thereof for minimizing the phase error.          A gain controlled amplifier is connected to receive the luminance signal and has a controllable gain for deriving a second phase control signal as a function of the luminance signal, this second phase control signal being applied to the local oscillator circuit to vary the phase thereof.  The gain of the gain controlled amplifier is varied as a function of the phase error between the chrominance reference component included in the VIR signal and the reference oscillating signal.  In one embodiment, the local oscillator circuit comprises a voltage-controlled oscillator which receives the first phase control signal as the control voltage therefor, the output of this voltage-controlled oscillator being coupled to a controllable phase shifter which receives the second phase control signal.  In another embodiment, the local oscillator circuit is a voltage controlled oscillator whose phase is controlled by the output of a matrix circuit, the latter receiving both the first and second phase control signals.  In this embodiment, a differentiated version of the luminance signal is amplified by the gain controlled amplifier to produce the second phase control signal.     -i-

Abstract: A B S T R A C T     An enclosure containing rotating blades for mechanical stirring of gaseous fluids may be a heat exchanger; flue gas energy recovery device, gas generator or combustion device.  A high rotational stirring velocity increases the convective heat transfer rate, rendering it independent of the lower throughput velocity of primary fluid which can be control-led independently of the stirring speed.  Primary fluid is isolated from a secondary fluid by a thermal transfer surface which is continuously swept by the swirling primary fluid and which may be the peripheral wall of the enclosure or a flow tube located proximate the peripheral wall. In one embodiment, swirling is achieved by radially-extending blade assemblies secured to a rotatable shaft at longitudinally spaced locations to establish discrete swirling zones in which fluid recirculates from the shaft outwardly. along the wall, and back toward the shaft.  In another embodiment, the blades extend longitudinally, proximate the peripheral wall, from peripheries of horizontal discs which rotate with the shaft.  In this embodiment, primary fluid follows a restricted helical path, maintaining continuous contact with the thermal transfer surface, away from the shaft.  Either embodiment may be converted to a combustion system by igniting primary fluid in the presence of admitted air.  In all embodiments recirculation of primary fluid condensate, injected water or additive optimizes heat transfer via latent heat of vaporization and dropwise condensation.          Blade rotary speed may be varied to commonly or independently control: combustion fuel and air flow; primary fluid flow; and stirring energy.

Abstract: Abstract of the Disclosure An adaptive differential pulse code modulation system is described in which the problems of instability and deterioration of signal to noise ratio are mitigated.  The transmitter of the system includes a subtractor for obtaining the difference between an input signal and a predicted value, a quantizer for quantizing the output signal given from said subtractor, and a decoder which stores the output signal given from said quantizer, multiplies at least one past signal of those output signals given from said quantizer by at least one coefficient, calculates the sum of the products as results of the multiplications, adaptively corrects the coefficient so as to lessen the output signal given from the quantizer, and produces the sum of the products as a predicted value or a part of the predicted value.  The receiver of the system includes a decoder which receives and stores the output signal given from the quantizer in the transmitter, multiplies at least one past output signal given from the quantizer by at least one coefficient, calculates the sum of the results of the multiplications, adaptively corrects the coeffici-ent so as to lessen the output signal given from the quantizer, and produces the sum of the multiplication results as a predicted value or part of the predicted value, and an adder for calculating the sum of the predicted value and the output signal given from the quantizer and producing it as a repro-duction signal.

Granted: 1982-05-25
Abstract: ABSTRACT OF DISCLOSURE     Disclosed herein is an electronic timing circuit which can be incorporated in an accelerator pump timing control, also disclosed herein.  The timing circuit is adapted to be connected to the first and second power terminals of a DC supply and for energizing a load, for example, a fuel pump solenoid valve, during a predetermined timed cycle.  The circuit includes a thyristor having an anode-cathode path adapted to be connected to the load so that when the thyristor is rendered conductive by a trigger pulse applied to the gate, current flows from the DC supply through the thyristor to energize the load and start the timed cycle.  A transistor control circuit including a transistor connected in series relation with the anode-cathode path is operable for controlling the energizing current flow through the thyristor, subject to a relaxation oscillator included in the timing circuit.  The relaxation oscillator produces a stop pulse a predetermined time after the start of the timed cycle for rendering the transistor operative to interrupt the energizing current flow through the thyristor and to thereby deenergize the load and end the timed cycle.

Abstract: ABSTRACT OF THE DISCLOSURE         A unique ground fault circuit interrupting (GFCI) device is utilized to control either an industrial circuit breaker of a contactor in protecting a large power distribution circuit against ground faults.  The GFCI device is equipped with plural sets of the GFCI device.  The particular switch contacts are selected to control energization of an actuator adapted to the circuit breaker or contactor, depending on the actuator type.  A ground fault sensor responds to ground faults on the distribution circuit by injecting a current imbalancing signal into the GFCI device, causing it to trip.  The consequent switch contact actuation initiates operation of the circuit breaker of contactor to interrupt the distribution circuit.

Abstract: ABSTRACT OF THE DISCLOSURE         A helical member comprises a continuum of coaxial, helixes disposed in spaced longitudinal relation which define an axial aperture that is adapted to receive an external connecting device such as a line or anchor pin.          An elastic core is disposed within the aperture in frictional engagement with at least one of the helixes.     One end of of the core is attached to the member and a free end extends out of the aperture.  Gripping the free end and stretching the core reduces its cross-sectional dimensions which releases the frictional engagement and provides sufficient space to admit the connecting device.  Releasing tension on the core substantially restores its original dimensions and releasably grips the connecting device between the core and at least one helix to provide a simple, yet effective attachment.
