Abstract: DUAL LOAD CONTROL CIRCUIT               ABSTRACT OF THE DISCLOSURE A control circuit provides full range power control to a pair of electrical loads via a single two-wire power cable by controlled switching of a bidirectional solid state switch during each consecutive half-wave cycle to supply power to one load during each positive half-wave cycle and to the other load during each negative half-wave cycle.  The switching during each half-wave cycle is con-trolled by a respective trigger circuit.  Interference by power supplied to one load with the operation of the other load is prevented by removing any residual voltage from the respective trigger circuit at the end of each half-wave cycle.

Abstract: RCA 76,982 ABSTRACT OF THE DISCLOSURE           In a television receiver, apparatus for non-linearly processing a vertical detail signal includes first and second cascaded amplifiers which exhibit linear and limiting regions for processing a vertical detail signal.  A first keyed sample and hold circuit provides detail signal amplitude samples to the first amplifier.  A second keyed sample and hold circuit provides amplitude samples of sampled detail signals from the output of the first amplifier, to the second amplifier.  The sampling circuits operate at different times such that the second sampling circuit is operative in a sampling state at times when the first sampling network is inoperative and exhibits a holding state.  Output detail signals from the first and second amplifiers are combined with a linear version of the vertical detail signal to produce a combined, output vertical detail signal manifesting signal coring, amplification, and paring (attenuation) over selected amplitude ranges.

The interior of the housing is filled with a hardened filler material which completely surrounds the bare portions of the conductors, the beads which are formed on such bare portions, the sleeves which are shrunk onto the bare portions of conductors between the respective beads and the insulators for the conductors, and a tension reducing clamp which surrounds the outer sheath of the cable in the housing.  The aperture at one end of the housing contains an O-ring which is biased against the external surface of the outer sheath of the cable and against the surface surrounding the aperture by a second ring.  The conductors are further surrounded by additional insulators which extend from the filler material by way of an open end of the housing. The beads are welded or soldered onto the bare conductors between the respective pairs of insulators.

Abstract: ABSTRACT The method disclosed is one wherein n pumps and n relative solenoid valves operated by a single microprocessor controll-ed stepping motor dispense one or more of n colouring agents into a paint/varnish medium. The quantity dispensed is either a proper of improper fraction of an integer of 1/m of the volumetric unit of measure (fluid oz) and is defined p,  a nominal value reflecting the number of half-steps indexed by the mdor which is corrected proportionally by comparison of the effective and the nominal weight of a droplet downstream of the pump and upstream of the solenoid valve in order to produce an effective number of half-steps x. A similar correct-ion is made to the number R of half steps which correspond to the delay occasioned by operation of the solenoid valve, comparing the effective and-nominal  weights of the droplet downstream of the valve; the speed of the motor is corrected to compensate for system resistances. The machine comprises a single motor (26) operating the n pumps (25) which dispense colouring agent from n relative containers (16) by way of n nozzles (8) located above  a vertically-mobile platform (4) on which the container (2/3) with the medium is placed, its position controlled by a photocell (15). All of these components are housed in a cabinet comprising a basic framework (1) the top surface of which accommodates a computer (22-23-24) with circuit boards controlling operation of the machine according to the method as disclosed; data is displayed by video and documented by a printer.

Abstract: Abstract of the Disclosure The present invention provides a photodosimeter for use by sunbathers and the like and which activates an alarm when a predetermined radiation dosage has been received by the user.  The photodosimeter includes a photocell mounted within the housing and exposed to sunlight through a housing opening.  This photocell generates an analog output signal proportional to the radiation which impinges upon the photocell.  An A/D converter converts the analog signal to a digital signal which is connected to a microprocessor which periodically samples the output from the converter and updates a cumulative radiation dosage counter in memory. When the cumulative radiation dosage exceeds a user settable maximum an alarm is activated.  The microprocessor is further programmed to test a plurality of electrical conditions of the photodosimeter and to activate the alarm by a fail safe conduit in the event that one or more conditions are unsatisfied. Specifically, the microprocessor compares the determined radiation dosage to ensure that it falls between 0 and a predetermined maximum amount which are indicative of a nonfunctioning and overload conditions, respectively. The microprocessor further compares the read radiation dosage with the previous maximum amount and, if the current radiation dosage is less than a predetermined percentage, for example 25%, of the maximum amount, indicative that the photocell has been covered or obscured, activates the alarm.  Still other electrical conditions of the photodosimeter are reiteratively checked by the microprocessor.
