Abstract: Abstract of the Disclosure A gated diode switch requires a voltage applied to the gate which is more positive than that of the anode and cathode in order to break current flow between the anode and cathode.  In addition, a current of at least the same order of magnitude as flows between anode and cathode must flow into the gate of the switch to break current flow.  The use of a second gated diode switch coupled by the cathode to the gate of a gated diode switch which is to be controlled provides a high voltage and current capability means for cutting off (interrupting) or inhibiting current flow through the gated diode switch. The state of a gated diode switch is thus controlled by a second gated diode switch.  The state of the second gated diode switch is controlled by a circuitry consisting of an n-p-n transistor at least one p-n-p transistor, and at least one diode.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention is a system for accurately phase locking two signals having the same frequency but which are of arbitrary two signals having the same frequency but which substantially higher frequencies.  Elements of two signal are stored at sequential address locations in a pair of ROMS.  An oscillator drive a counter which provides a sequential address output signal, which is used to address the first ROM   A binary signal which can be generated from a manual control calibrated in 360° provides a phase control signal which is added to an address signal generated from the same oscillator, and which is used to address the second ROMs  The Increment between the two ROMs established from the control provides control over the phase differential between the two generated signals.   Since the addresses of both ROMs are generated from the same oscillator, their frequencies are the same, and their phases are locked at the desired phase differential.

Abstract: Abstract of the Disclosure A method of preparing a thermoplastic, water-soluble, phenolic aldehyde resin and the composition are provided to enhance the flexibility and resistance to compression fatigue breakage of glass fibers to which the resin has been applied. The method involves two steps. In the first step, the phenolic compound and the aldehyde are reacted to less than 100 percent completion in an amount so that the aldehyde to phenolic compound ratio is in the range of about 0.6 to about 1.5 and at an acidic pH and for a period of time equivalent to about 3 hours to about 10 hours when the temperature is in the range of about 55°F (13°C) to about 90°F (32°C) to produce a resinous mixture. In the second stage the pH of the reaction is adjusted within the range above about 7.0 to about 7.5 and the reaction is con; rued between the unreacted phenolic compound and aldehyde and resinous mixture to product a resinous mixture composition that is thermoplastic, and water soluble and has trimer polymer with slight cross-linking and dimer and no higher oligomer polymers. The phenolic aldehyde resin mixture is processed into an adhesive system by combining it with one or more elastomeric latex and various latex additives. The adhesive system is aged and has added to it an amine or ammonia to tie up any unreacted aldehyde. Also additional phenolic compound may be added. The adhesive system is used to coat filamentary materials and the coated filamentary materials are dried to produce reinforcement material for rubber.
