Abstract: 1,186,597. Pulse circuits. COMMISSARIAT A L'ENERGIE ATOMIQUE. 8 June, 1967 [9 June, 1966], No. 26561/67. Heading H3P. [Also in Division G1] A detection apparatus incorporating a detector 2 which produces a signal whose amplitude is a function of the energy associated with an event such as the arrival of a charged particle, provides two outputs, one whose level corresponds to the amplitude of the detector signal, the other being in the form of a short pulse occurring at the time of commencement of the detector signal, so that the time of occurrence of this may be accurately displayed. The apparatus incorporates a negative feedback power amplifier whose output represents the signal amplitude and thus the particle energy. The amplifier has a first cathode follower type stage 5 having a cathode load impedance 8 across which a fast amplifier 1 is connected. This amplifier responds to the initial surge of current through the impedance 8 which occurs when an input signal is received before the feedback is established in the amplifier, to provide a sharp output pulse coinciding in time with the time of commencement of the input. The impedance 8 may be a short-circuited delay line, an inductor and resistor in parallel, or a transformer.

Title: Method of determining the varying equipment delays for pulse trans ponder
IPC: G01S13/78
Filed: 1970-06-02
Abstract: 1308629 Pulse radar; transponders INTERNATIONAL STANDARD ELECTRIC CORP 2 June 1970 [7 June 1969] 26626/70 Headings H4D and H4L In a secondary radar transponder, variable apparatus delay is determined utilizing a pulse abstracted from the transmitter and the result of the determination is utilized to compensate for the delay. The invention is described as applied to a TACAN ground beacon, a sample of the response pulse pair from transmitter power amplifier SL being demodulated, MDM, and thence applied to an AND gate U4 for suppressing the second pulse of the pair; the first, "measuring", pulse is applied via OR gate 02 to network VG which imposes the standard delay of approximately 33 microseconds. (True incoming pulse pairs are identified by a decoder which consists of a shift register SR, delay network VG and AND gate U2, and produces a single pulse at the output of gate U2 for a true incoming pulse pair, the single pulse enabling a trigger circuit T which starts a ring counter RZ: with uninterrupted clock pulses applied to counter RZ the latter passes through zero every 50 microseconds-the predetermined time between interrogation and reply-to cause an encoder C to issue a pulse pair for modulation of the transmitter). If a pulse from register SR is absent, AND gate U2 prevents the output of delay circuit VG from reaching counter RZ and at this instant the second input of an AND gate U3 is energized instead to enable the measuring pulse to reach modulator MM. An attenuator DG adjusts the amplitude of the measuring pulse-now at intermediate frequency I.F.-to ensure that any delay in I.F. amplifier VZF is the same for the measuring pulse as for the received pulse pair. On arrival of the demodulated measuring pulse an AND gate U5 is energized and an AND gate U1 is inhibited, the measuring pulse actuating trigger T, via OR gate 03, to interrupt the counting in counter RZ. The interval between the previous zero passage of the counter and when interrupted is the internal delay in the transmitter and most of the receiver; this delay is allowed for with the next interrogation pulse since the count at which the counter is stopped is a revised preset magnitude from which the next cycle is begun.

[Class 135] A mixing-valve for at least two fluids, for example, hot and cold water, comprises valve members 5, 6 for controlling inlet pipes 1, 2 actuated by a cam 18 so that the proportions of the mixture are determined by the position of the cam which is operated by circular movement of a handle 28. The resulting mixture passes from chamber 17, through the hollow cam spindle 19, into a passage 37 in the handle spindle 29 from where its delivery is controlled by a valve 40 which is actuated by relative movement of a part 42 of the handle 28 into an outlet passage 38 of the spindle 29. The final delivery may be directed towards either of outlet branches 34 or 35 according to the position of the outlet passage 38 in relation to ports communicating with the branches 34, 35. The cam 18 is so designed that the range of movement for full communication with each of the branches 34 and 35 provides for a complete regulation of the proportions of the mixture. A single outlet branch only may be provided for the delivery if desired and in such an arrangement the valves 5 and 6 may both be closed in a certain position of the operating handle and a syringing flow obtained by communication of a port in the handle spindle 29 with a previously filled syringe container.
