Abstract: ABSTRACT OF THE DISCLOSURE The developer storage capacity of a development system for an electrostatic processor is increased by adding a passive reservoir to supplement the system sump.          Provision is made for maintaining a more or less continuous flow of developer into and out of the reservoir, including means for feeding developer from the reservoir to the sump whenever the supply of developer within the sump drops below a predetermined level.  In a cascade development system, a hopper having a constricted discharge orifice leading to the development zone of the processor is filled to overflowing with developer so that there is a substantially constant head causing the orifice to meter developer into the development zone at a substantially uniform rate.  The reservoir is, in turn, positioned to intercept the overflowing developer and to feed developer into the sump whenever the supply of developer therein drops below the bottom of the reservoir.

Abstract: Abstract Analog signals initially are stored in a linear array such as a charge coupled device (CCD) register.  There is provided, for each stage of the linear array, a different column of a CCD matrix, termed here a B register.  During a transfer interval, the analog charge signals concurrently are permitted to flow into the columns.  As the stages in the B register have much smaller charge storage capacity than the stages in the linear array, the charge signal fills and then overflows successive potential wells of each column until an equilibrium condition is reached.  At equilibrium, the number of filled wells in a column will be proportional to the amplitude of the charge signal supplied to that column by the stage of the linear array coupled to the column.  The matrix is read by concurrently sensing all of the signals present in one column, and then doing the same for each following column.

Abstract: Abstract of the Disclosure The invention relates to a circuit for protecting a plurality of series-connected thyristors against spontaneous ignition resulting from inadequate release time.  For the purpose of individual protection, a device producing a switching signal when the voltage becomes negative is associated with each thyristor.  This switching signal is transferred to an evaluating device.  This produces a time signal for a monitoring period corresponding to the period of protection of the thyristor.  A second switching signal is produced when the voltage becomes positive.  When this second stitching signal occurs during the said monitoring period, the ignition circuit is triggered.

Abstract: ABSTRACT OF THE DISCLOSURE                A stroboscopic tuning device for a stringed musical instrument that is mounted on the musical instrument adjacent to the strings to be tuned.  A solid state circuit employs a frequency generator, such as a piezoelectric crystal oscillator or a tuning fork oscillator, to operate the stroboscopic light source at a preselected frequency.  In the use of the device, a string is plucked, and when the vibratory motion of the plucked string is either the fundamental frequency or the harmonic frequency of the preselected operating frequency of the stroboscopic light source, the string will appear to an operator to be in a nonvibrating condition.  At that time, the string is tuned or adjusted to the desired tone.
