Abstract: ABSTRACT OF THE DISCLOSURE            An improved technique for standardizing a basis weight gauge used to measure the weight per unit area of sheet material is described.  The gauge is of the type that has a radiation source and detector defining a gap through which the sheet material is fed and across which the radiation is directed.  The amount of radiation detected is a measure of the basis weight of the material.  The gauge also includes a standard disc having a predetermined and stable basis weight and which can be swung into the radiation path.  The method involves firstly constructing two calibration curves each showing basis weight on a first axis versus a function of transmission ratio on a second axis, the first calibration curve being constructed without simulated dirt and the second calibration curve being constructed with simulated dirt.  The next step is the construction of a standardization curve by plotting the displacement of one calibration curve relative to the other measured parallel to the first axis.  The gauge is standardized during operation by placing the standard disc in the gap without the sheet material in the gap and determining the standardize transmission ratio,determining a correction factor based upon the standardize transmission ratio and applying the correction factor to the uncorrected basis weight to determine a corrected basis weight.

Abstract: ABSTRACT                   SENSOR ARRAY     A sensor array, usually a sensor matrix for sensing pressure,  comprising  a  grid  of  conductors  in  a  woven fabric, the row conductors (10) crossing over the column conductors (12) to form a matrix array of crossover points (15).  The rows are separated from the columns by indivi-dually coating the conductors of one or both series with an electrically partially resistive fibrous material (14), so that when the conductors at any crossover point in the array are pressed closer together, the resistance between the two conductors at that crossover point decreases.  By connecting  the  conductors  to  suitable  electrical  cir-cuitry, the force applied at any crossover point and the location of that crossover point within the array can be determined.

Abstract: ABSTRACT         A code converting system according to the invention has a first code converter for converting a first code result-ing from the encoding of multi-level signals in a prescribed manner into a variable length code, and a second converter for converting the first code into a run-length code.  A selector selects either the variable length code or the run-length code in response to a selection signal, and supplies the selected code to a memory.  The memory stores the output of the selector, supplies it to a transmission line at a constant speed, and at the same time generates a signal of the memory occupancy by counting the quantity of codes stored therein.  A control cir-cuit controls the selector to output the variable length code when the memory occupancy is below a prescribed level.  The invention lessens deterioration of picture quality, permits fine control of the encoding and avoids the complicated hardware structure of prior systems.  Furthermore, underflow can be pre-vented by finely controlling the occupancy of the memory.

Abstract: ABSTRACT      An in duct humidification and evaporative cooling system for industrial and commercial buildings is disclosed.  Air and water under pressure are utilized to atomize water into minute droplets which rapidly evaporate and raise the level of relative humidity while producing evaporative cooling.  A first relative humidity sensor/transmitter produces a signal proportional to the relative humidity of return air, and a second relative humidity sensor/transmitter provides a signal proportional to the relative humidity of supply air.  Preset receiver-controllers external to the duct receive the two signals and send them to a low signal selector which in turn sends the lower signal to a modulating water valve and to an electrical switch which opens a valve in the pressurized air supply line.  A second electrical switch operatively connected in the air supply line opens a valve in the pressurized water supply line.  Air and water from the two supply lines are delivered to in duct air and water manifolds and to spray heads on the air manifold to maintain automatically the required humidification and cooling parameters.

Abstract: ABSTRACT OF THE DISCLOSURE      An apparatus for detecting degradation of a grounded arrester, including a wave conversion circuit for producing an output signal corresponding to the total leakage current flowing through the arrester, and a phase shifter circuit coupled to the output signal for providing a capacitive-component leakage current signal, which is cancelled from the total leakage current signal by means of a differential amplifier to produce a resistive-component leakage current signal.          According to one embodiment, this latter signal is applied to a synchronous rectifier circuit for synchronous rectification of the output signal from the differential amplifier circuit.  A real resistive-component leakage current signal is then detected by adjusting the phase shift amount in the phase shifter circuit so that the output signal from the synchronous rectifier circuit may become zero, thereby bringing the phase of the cancelling wave signal in agreement with the phase of the capacitive-component leakage current signal.  In another embodiment, the resistive-component current leakage signal is applied to a multiplier and a time averaging circuit, the output of which is likewise nulled by means of the adjustable phase shifter.
