Abstract: Abstract of the Disclosure The invention relates to the manufacture of plywood.  It is known to use in adhesive for plywood manufacture various extenders and a commonly used one is comminuted corn cobs.  Comminuted corn cobs have recently been in short supply, which has led to attempts to find other satisfactory extenders.  It has now been found that comminuted bark of aspen trees can satisfactorily be used in place of comminuted corn cobs and that there arises an unexpected advantage when using the comminuted bark.  The maximum assembly time, i.e. the time which can elapse between the start of laying up of the veneers to form the plywood and the application of heat and pressure to cure the adhesive, is increased.

Abstract: REFRESH COUNTER     ABSTRACT OF THE DISCLOSURE     A refresh counter which uses existing address buffers and is implemented with refresh address storage and decoders.  The address buffers act to multiplex the refresh address storage outputs as inverted outputs when properly enabled.  When all lower order bits are true at a  particular unit of the refresh counter and a transfer clock signal occurs, the outputs of the buffer are transferred to the refresh storage  where the buffer multiplexes them when enabled.          The clocking scheme is structured to enable only at the end of a re-fresh cycle.   In this manner, the counter is incremented at the end of each refresh cycle.

To this end, the gas mixture is admixed with at least the stoichiometric amount of oxygen and/or of oxygen-containing gases necessary to achieve conversion of the total phos-phorus contained in the gas mixture to oxidation level V. The resulting mixture is introduced into a reaction zone maintained at a temperature within the range 200 to 700° C and allowed to remain therein over a period of 0.5 to 20 seconds. Resulting phosphorus-V compounds are finally separated from the gas mixture.

Abstract: Abstract Input offset voltage compensation in an amplifier is provided by a feedback capacitor in a feedback loop. For periodically resetting the compensation, the signal input terminal is grounded by an electronic MOSFET switch.  Other such switches close the feedback loop in front of the capacitor and connect the output side of the capacitor to ground for recharging.  An input capacitor for compensating the switching feed-through charge of the feedback loop switch is connected between the input signal source and the signal input terminal.  The ratio of the inherent capacitances of the switches is equal to the capacitance ratio of their respective capacitors.

Abstract: ELECTROACOUSTIC NETWORK            ABSTRACT OF THE DISCLOSURE         Disclosed is a passive delay network for insertion in the high frequency signal path of a crossover network in a high fidelity loudspeaker.  The delay network provides a device to adjust the optimum listening window electrically rather than by changes in the physical construction of the speaker cabinet.  Electroacoustic high frequency and low frequency drivers may be mounted in a planar baffle or mounted co-axially.          The delay network retains a "flat" amplitude-frequency charac-teristic and minimizes time dispersion in the acoustic signal received by the listener.  Correction for time delay is most important near the transition frequency of the crossover network because near the transition frequency substantially equal sound energy is radiated by both the high frequency and low frequency drivers.  Also disclosed is a novel construction for a co-axial driver combination and a technique for adjusting both the delay in the electric delay line network and the air path delay of electroacoustic drivers.  The co-axial drivers include sound absorbant material between the drivers to prevent direct sound radiation between the low and high frequency drivers.  The adjustment technique comprises a method of experimentally testing and adjusting the mutual inductances in the electric delay line and the air path delay.
