Abstract: ABSTRACT OF THE DISCLOSURE            Defect formations and unwanted indiffusions caused by residual impurity products is prevented in a semiconductor fabrication method which includes the step of forming a composite mask which simultaneously defines for instance base, collector and diffusion isolation openings. After these openings are defined a thin protective layer of silicon dioxide is grown over the exposed area and remains there throughout the remainder of the doping process which includes the steps of selectively covering areas which are not to be doped with photoresist and thereafter ashering the photoresist to remove it in preparation for the next ion implantation step. The thin protective layer of silicon dioxide protects nonselected areas against residual impurity products formed during removal of the photoresist.

Abstract: ABSTRACT         The method for heating the furnace chamber produces high momentum levels during the heat treating cycle so as to obtain sub-stantially uniform temperature throughout the charge.  The method includes initially firing a plurality of high velocity burners at substantially maximum fuel input and in substantially stoichiometric ratio.  Thereafter, the fuel input is reduced while maintaining the stoichiometric ratio at least during the high input portion of the cycle.  Excess air is introduced external of the combustion zones of the burners on a predetermined signal such as a given fuel input reduction to maintain the desired momentum level within the furnace.  The apparatus comprises a high velocity burner having associated therewith an excess air unit for discharging excess air external of the combustion chamber or part block of the burner.  The excess air unit can be integral with the burner so as to supply excess air through the burner port block or a separate unit can be provided which is connectable to the burner and about the port which defines the com-bustion chamber.

Abstract: ABSTRACT OF THE DISCLOSURE:           A circuit for producing sinusoidal wave-forms representative of signals used in voiceband signaling for telephone dialing, frequently referred to as DTMF signaling.  A sine wave is broken into a predetermined number of time increments.  The amplitude changes for each increment may be indicated in the form of a binary digital word for a quadrant of the curve.  The remaining quadrants will exhibit essentially the same change characteristics at like time increments with only the bit order reversed or the polarity changed thus, the basic binary word is unchanged for each quadrant. A programmable memory is set to produce the binary word at a selected clock rate.  In this way, synthesis of a plurality of sine waves may be readily produced using delta modulation techniques.  For all sine curves, the number of time increments remains the same, the rate of pulsing the increments is varied responsive to the keyboard signals generated.  For tele-phone use, a high and a low signal are synthesized at essentially the same time.  These signals may further be combined on a single output for transmission to the tone receiver.

Abstract: FOLDING FLEXIBLE UNDERCUTTER PLOW            ABSTRACT OF THE DISCLOSURE          Apparatus is disclosed for folding an articulated agricultural implement such as a multisection plow in order to facilitate movement of the implement from field to field along avail-able roadways.  Stability in the folded condition and minimization of the number of hydraulic cylin-ders required are achieved through the use of a gravity operated lock arrangement associated with adjacent sections of the foldable wing frame units of the implement.  The number of locks and hydraulic cylinders depends upon the total number of hinged sections used to form the base and wing units of the frame assembly.  The inboard hydraulic cylinders are pivotally connected to respective draft beams on the base unit and each acts directly between such beam and the associated wing unit.  The arms of the hitch are connected to the forward ends of the draft beams, and the arrangement is such that the overturning moment created during folding of a wing unit is opposed by a sufficient equal and opposite force to maintain equilibrium and prevent arching or buckling of the flexible frame sections.  The hitch arms con-verge at a special nose provided with a tongue connec-tor that is continuously adjustable over a wide elevational range to accommodate various tractor drawbar heights.  Each gang of a multiple gang treader behind the plow runs askew and is provided with a gang check to limit forward swinging movement and thereby prevent the treader wheels of adjacent gangs from engaging each other and damaging the wheels when terrain irregularities are encountered.

Abstract: TRANSMISSION CONTROL SYSTEM              Abstract of the Disclosure A control system to change gear ratio in an automatic transmission through friction elements engaged by hydraulic pressure.  A closed loop electrical circuit is completed between a transducer, which provides an electrical signal related to the output torque of the transmission, and a pair of control valves, to vary the pressure applied to a friction element by each control valve.  A circuit for computing reaction torque is coupled between the transducer and a logic control circuit, which provides logic command signals for controlling operation of components in the closed loop circuit.  The system computes an output torque ramp when a downshift is called for by the shift point computer and uses controllers which react oppositely to control engagement of a clutch and brake in response to error signals of torque output compared to a desired ramp to produce a proper shift.
