Patent CA-1099344-A (CA)

Abstract: JOSEPHSON SELF GATING AND CIRCUIT        AND LATCH CIRCUIT                    Abstract of the Invention A Josephson Self Gating And circuit which is powered by pulsed or clipped alternating current and provides true and complement outputs in response to true and complement inputs is disclosed.  Inputs applied during the duration of the applied pulsed power or clipped alternating current are delivered to outputs which are maintained in that state in spite of a change of input within the given pulse duration.  In one embodiment, the presence of an output signal interrupts a current path which, in turn, disables a pair of AND gates.  These gates, even though the input to them changes, can provide no other output until the applied power falls to zero resetting the pair of AND gates which are latching in character.  In another embodiment, current paths of one AND gate are cross-coupled with a current path of another AND gate.  The interruption of current in a serially disposed Josephson device in one or the other of the current paths disables one or the other of the pair of AND gates preventing a change in outputs until the next cycle of applied pulsed or alternating current power.  A latch circuit incorporating a pair of AND gates, a flip-flop and a Self Gating And circuit is also disclosed.          The latch permits an input different from a previously applied input to the flip-flop to change the state of the flip-flop without changing the output of the Self Gating And during the application of a cycle of pulsed or alternating current power.  The changed input to the flip-flop appears at the output of the Self Gating And circuit during the next cycle of applied pulsed or alternating current power.

Abstract: IN-MOLD COATING OF SHEET MOLDING COMPOUND MOLDINGS                  Abstract of the Disclosure Liquid compositions suitable for hot post-mold coating of cured sheet molding compound (SMC) parts com-prise a reaction product of an epoxide and an unsaturated carboxylic acid mixed with a low shrink additive and a filler having a sheet-like structure.  These liquid com-positions are used to smooth surfaces, fill porosity and other voids and to eliminate or reduce sink marks.          Coatings typically are cured in less than two minutes and appear able to provide many features of normal paint-ing without paint facilities except possibly those needed for touch-up.       The application method used to date has been to compression mold an SMC part in the usual way, separate the mold halves, inject the liquid composition and re-close the mold for a second cure cycle.  A unique feature of the liquid composition is its ability to adhere to an uncleaned SMC molding.

Abstract: ABSTRACT OF THE DISCLOSURE          A microwave heating apparatus comprises a heating chamber, a microwave generator and heating resistors selectively connected through first and second switches to a power supply, and a control circuit connected through the first switch to the power supply.  The heating apparatus also comprises heating resistor coupling units each including a displaceable member and a third switch.  The displace-able member is displaced when the heater end is inserted to a predetermined position in the coupling unit, and the third switch is closed when the displaceable member is displaced. The third switch is connected in series be-tween the first switch and the control circuit.  The high frequency  radio  wave generator or the heater is thus not connected to the power supply unless the heater end is com-pletely connected to the heater coupling unit.  According-ly, it can prevent external leakage of microwaves, insu-lation breakdown or other related incidents.
