Abstract: 1,099,487. Pulse amplitude discriminating circuits. T.I. (GROUP SERVICES) Ltd. Oct. 5, 1966 [Oct. 12, 1965], No. 43193/65. Heading H3P. [Also in Division G1] A signal amplitude discriminating circuit comprises a first detector 12, responsive to signals above a first amplitude, a second detector 13 responsive to signals above a second greater amplitude, a delayed signal being produced from the output of the first detector 12, the circuit providing an output categorized as low amplitude if the second detector 13 is not in its actuated state when the delayed signal occurs and categorized as being of high amplitude if the second detector is in its actuated state when the delayed signal occurs. The circuit described is applicable to the detection of holes and oxide and sulphide inclusions in steel as described in Specification 1,098,575. Light reflected from the specimen impinges on a photomultiplier 10 which is arranged to provide a high amplitude signal corresponding to a hole or an oxide inclusion and a lower amplitude signal corresponding to a sulphide inclusion, the signals being amplified at 11 and fed to Schmitt trigger low and high level discriminators 12, 13. In order to prevent the sloping edges of high level signals being categorized as lower level signals, the signals from the low level discriminator 12 are differentiated and fed to a monostable multivibrator 17, responsive to the leading edge of each signal and a further monostable multivibrator 18 responsive to the trailing edge. The resultant pulses are combined by OR and AND gates 19, 20 so as to provide a pulse from 20 of the same duration as that from 12 but delayed in time. The pulse from 20 gates the output of a 45 kc/s. pulse generator 28 the gated pulses being fed to a counter 24 which indicates the duration of signals from the low level discriminator 12. Each pulse from the high level discriminator 13 is prolonged by a monostable multivibrator 21 and OR gate 22, the prolonged signal being fed to an AND gate 26 which passes pulses from 28 only in the combined presence of the delayed low level signal from 20 and the prolonged high level signal from 22. These pulses are counted at 25 to indicate the duration of oxide inclusions. Modifications.-A further AND gate 27 may be included so that counter 24 determines the duration of sulphide inclusions. The pulse generator 22 may be fed to a timing counter which switches off the apparatus after counting one million pulses. The outputs of the counters 24 and 25 then represent one million times the volume fractions of the relevant inclusions. The counters 24, 25 may alternatively be arranged to record the total number of incoming signals, the number of signals of each amplitude or the number of signals of each amplitude greater or less than a predetermined length.

A temperature control system for an incubator 4 comprises a thermostat 16 responsive to the temperature of the air in the incubator, a thermistor 20 responsive to the body temperature of the occupant of the incubator and a second thermostat 23 all connected in series between a current source 13, 14 and an electric heating element 7 in the incubator, the arrangement functioning to maintain a desired body temperature of the occupant. With the thermostat 16 set at its maximum setting by means of a control knob 26 an associated cam 28 operates a microswitch 18 to connect the thermostat 16 to thermistor 20. Thus after placing an infant in the incubator 4 the initial control of current to the heater 7 is exercised in a cyclic manner by the thermostat 16 to cause a rapid increase in the temperature inside the incubator, the resultant rise in the body temperature of the infant thereafter causing the thermistor 20 to assume control of the heating current. Should the control knob 26 be operated to set the thermostat 16 below its maximum setting cam 28 operates the microswitch 18 to connect the thermostat 16 to the by-pass 21, then the thermistor 20 is removed from the control of the heating current. Thermostat 23 is set so as to disconnect the heater 7 from the supply should the air temperature in the incubator rise about a desired limiting value. Elements 33, 34; 37.. 39 are various indicating devices such as lamps or buzzers.

[Also in Divisions F2 and G3] In an antiskid braking system, a sensor 32 generates an alternating signal of frequency dependent on wheel speed which signal is rectified and the resulting pulse charge capacitors 120, 128 to voltages dependent on the wheel speed. Temperature compensating diodes 123, 124 are provided to correct the voltage on capacitor 120. The resulting D.C. signal is differentiated and amplified and fed to a differential amplifier 160, 170 also fed with a reference signal set on a potentiometer 171. If the resulting signal at the collector of transistor 160 is less than a predetermined value, a monostable multivibrator 220, 230 is triggered to deliver a pulse through amplifier 90. The trailing edge of this pulse turns off a transistor 210 to start a Miller integrator 200, 201, 202 and when the voltage on the base of transistor 190 rises above that on the base of transistor 180, the multivibrator is again triggered, so that the pulse repitition rate varies with the voltage applied to the base of transistor 180. If this voltage is sufficiently low, it is always less than that on the base of transistor 190 so that a continuous D.C. signal is transmitted through amplifier 90.

Abstract: <PICT:1108027/C4-C5/1> A light (visible or near infra-red) emitting junction diode is produced by epitaxially depositing an N-type layer 1 of GaAsP on a substrate 2 or semi-insulating GaAs 0.010 inch thick for instance, making a cavity in the substrate, and diffusing-in a donor impurity Zn to form a P-type region 4.  The cavity is produced by air abrasion the diode being completed by plating a gold layer 5 over P-type region 4 and a small area gold layer 6 on the surface of the N-type layer 1.  The side wall of the diode may be tapered, as shown, to reduce internal reflection losses.  The efficiency of the diode may be enhanced by increasing the phosphorus concentration of the epitaxial layer as the deposition progresses; this decreases the attenuation of the radiation by the parts of the N-type layer remote from the junction.
