Abstract: ABSTRACT:      In apparatus for the automatic infusion of labour-inducing drugs during childbirth, in which the dose rate is steadily increased until a particular level of contraction activity is detected and then held con-stant, this constant rate can result in over-stimulation of labour.  The improvement comprises the inclusion of a dose rate control system in which the duration and period-icity of the labour contractions are detected in the form of a pulse train from which a signal is produced by integration, which signal is representative of the average value of the mark-space ratio of the pulse train.  This average value is compared with a predetermined value and the dose rate is increased or decreased according to whether the average value is less or greater than the predetermined value.

Abstract: IMPROVED PROCESS FOR PRODUCING INTEGRATED        CIRCUIT DEVICES BY ION IMPLANTATION            Abstract Of The Disclosure In this process of producing a bipolar transistor, all the regions of the device except the emitter region are formed by ion implantation through an inorganic dielectric layer of uniform thickness.  Subsequently, all the contact openings to the emitter, base and collector are formed and the emitter is implanted through the emitter contact open-ing.  This unique combination of process steps permits the use of a surface insulating dielectric layer of uniform thickness, wherein all capacitances are uniform and con-trollable while still permitting direct implantation of the emitter, which, because of its shallow depth is difficult to implant through an oxide.

Abstract: TITLE          APPARATUS AND METHOD FOR DETECTING SUBSTANCES FOR REGULATING CURRENT            ABSTRACT OF THE DISCLOSURE         An apparatus and method for sensing liquids, vapors and gases, which includes a conventional detection device operated in a non-linear region or current satur-ated condition so that it becomes sensitive even to sub-stances having a Van der Waals' constant "a" of nine or less. A change in the level of either the current through the detection device or the voltage across the detection device occurs upon exposure of the device to the sub-stance being sensed.  This current or voltage change is then detected to indicate the presence of the sensed sub-stance.  The relatively small current or voltage change associated with the detection device may be easily sensed by placing the detection device in a balanced bridge cir-cuit. Further, the bridge circuit enables easy, accurate normalization of the apparatus in a reference environ-ment.  The non-linear characteristics of the sensor allow it to be employed as a regulator for supplying a constant current to a power consuming device.

Abstract: ELECTRONIC APPLIANCE CONTROLLER WITH FLEXIBLE PROGRAM AND STEP DURATION CAPABILITY                      ABSTRACT OF THE DISCLOSURE     An electronic sequence type controller structure having a high degree of flexibility in programming the time durations of particula, steps in the program.  The controller which includes a digital program sequence counter capable of stepping from one state to the next in response to inputted clock pulses, each state representing a particular program step.  A programmable digital counter, programmed by a timer setting control, is operable to count inputted clock pulses and to output a signal when the number of clock pulses corresponding to a programmed time duration have been inputted.  A program memory is responsive to the state of the program sequence counter for directing the timer setting control to program a time duration desired for any particular program step into the programmable timer.  To direct the overall operation to effect periodic program advancing operations there is provided a control logic means.  In operation, the control logic means is operable to direct a clock pulse to the programmable timer for each program advancing operation in the event a signal has not been received from the programmable timer and a program step is therefore in progress.  When a program step is completed, a signal is received from the programmable timer and the control logic means is then operable to direct a clock pulse to the program sequence counter to cause stepping to the next program step, whereupon the program memory directs the timer setting control to program a new time duration into the program-mable timer.
