摘要： A digitally controlled two legged bridge comprising a component under test and a reference resistor selected from a decade ladder as a function of the exponent of the value of the component under test. A drive signal, whose amplitude is a function of the significant digits of the value of the component under test, and a reference signal are connected to selected points on the bridge in the appropriate waveform as a function of the component under test. The output of the bridge is fed back to the drive signal to balance the bridge and is compared with acceptable percentage error levels, for the component under test.

摘要： A high frequency thermode-driven device for use in hotbar soldering has a unitary metal support frame which is used for the secondaries of four individual transformers. The support frame also serves as the structural member to which the transformer and thermodes themselves are fastened. This is possible because the secondaries require only one turn; the upstanding ears of projections which extend radially outwardly from the support frame so as to protrude through the apertures in the transformer cores provide a source of voltage and become a secondary winding when connected to a load impedance, such as a thermode.

摘要： A computer controls a plurality of satellite machines in real time via a single bus comprised of undedicated, continuous transmission lines terminated at both ends in matching impedances. Each machine coupled to the bus is addressed and commanded during every computer cycle, responding only to signals directed to its address. When a machine is not electrically powered the computer provides an internal signal; computer cycles are never interrupted; continuous control of all other machines is maintained. Any number and mixed types of machines may operate from the bus simultaneously. Machines may be added or removed from bus, and machine programs may be added, removed or modified without interrupting operation of the other machines. Automatic safety reset is provided for machine or computer failure.
