Title: Radio frequency measuring methods and systems
IPC: G01R29/08
Filed: 1972-05-08
Abstract: 1338533 Evaluating frequency characteristics H SADEL 8 May 1972 [1 June 1971] 21305/72 Heading G1U A system for determining the frequency characteristic of a device under test 23, Fig. 1, includes a white noise generator 1 and a CW oscillator 4 which may effectively be selectively connected, by a switch 5 which applies a regulated voltage 11 either to the white noise generator or to the CW oscillator, to the device under test 23. The system is designed for use with a meter having a narrow input bandwidth whose centre frequency is tunable over the frequency range being examined, and it may be used either as mentioned above to test a device 23 or to test, i.e. to calibrate, the meter 13, which then itself constitutes the device under test, for use elsewhere. Calibration of the meter is done as follows. Switch 5 is set to energize the CW oscillator and the meter 13 is connected direct to the output terminal 16 and tuned so that its bandwidth embraces the CW frequency. The level of the CW signal is then adjusted 6 to some appropriate value, which can be read on a meter 7, and the meter is calibrated to this value. Next the white noise generator 1 is connected and its level control 18 and an attenuator 22 are adjusted in combination such that the meter 13 reads what it read when it received the CW signal. The meter 13 is then tuned over its centre frequency range and calibrated so that the value indicated after calibration correction, is constant. A device 23, such as an amplifier or attenuator, is tested using previously calibrated meters in a similar way. First, the CW signal is passed through the device under test and its level adjusted so that the meter indicates a convenient value for example Odb. Second, the white noise is applied and adjusted so that the meter still indicates the same value, and then the meter is tuned over the frequency range of interest. The system described also includes a bridge 24 so that with a switch 21 in its units position II a device 25 connected to one vertex 26 of the bridge, can have it reflected power measured.

Abstract: 459,313. Kinematographic targets. OFFICE GENERAL DE LA CINEMATOGRAPHIE FRANCAISE, and CHOLLAT, H., 39, Avenue Victor - Hugo, Paris. July 29, 1935, No. 21507. [Class 20 (i)] [See also Group XVI] A shooting booth comprises a casing 27 provided with an iron plate 16 to receive the impact of bullets and a moving screen 20 on which animated pictures are projected, the screen being wound alternately from one drum 7 to another drum 1 over rollers 28, 5, 4, 31, 32, 3, 2, 33. A supporting sheet 13 is wound very slowly from a drum 34 on to a second drum 35. The supporting sheet may be located between the runs of the screen sheet, as shown, or behind both runs. The impact of a bullet on the plate 16 may, through a vibrator coupled to the plate, or through a microphone responsive only to detonation, effect a stoppage of the picture film and of the screen, to show a stationary image registering the effect of the shot. The drums 1, 7 may be driven by an electric motor 9 driving a disc 36 through worm-gearing 10, the disc having a crank-pin 37 coupled by links 38, 41 to arms 40, 42 which are thereby oscillated about the drum centres. Pawls 44, 45 pivoted on the arms 40, 42 engage alternately with ratchet wheels 51, 50 on the drum shafts the engagement of the pawls being governed by a cam 60 mounted on a fixed pivot 59 and carrying an arm 58 coupled by a spring 55 to a lever 53 having a roller 52 which bears on the surface of the screen paper being wound on the winding drum. On completion of winding, the spring 55 moves over-centre and swings the arm 58 and hence the cam 60, so that one pawl is engaged and the other disengaged thus reversing the direction of motion of the screen. The lever 53 may also be provided with a link 65 actuating a ratchet mechanism (not shown), for advancing the roll 35 on which the supporting sheet is wound. An automatic reversing mechanism may also be fitted for the rolls of the supporting sheet.

Patent GB-844756-A (GB)
Title: Improvements in fault indicating circuits
Inventor: WYNDHAM PAUL IAN
IPC: H03F1/54
Filed: 1956-07-13
Abstract: 844,756. Protective arrangements. TELEPHONE MANUFACTURING CO. Ltd. June 26, 1957 [July 13, 1956], No. 21763/56. Class 38 (5). [Also in Group XL (c)] A fault-indicating arrangement for a plurality of electrical devices, e.g. valves A, comprises a current-responsive fault indicating means common to all the devices and a transistor J individual to each device. In the arrangement illustrated each transistor J (one shown) is of the PNP type and has its emitter connected through a common connection 1 to a constantvoltage source V and its collector connected through a common connection 2 to one terminal of the main winding RA of a common alarm relay which has its other terminal connected to the negative of the source V. The base of each transistor J is connected through a resistor r 1  to an appropriate point 3 of the cathode circuit of the associated valve A. The potential of the common connection 1 is normally maintained below that of the points 3 so as to reverse bias all the emitter-base junctions and prevent the flow of current from the emitters to the collectors, the winding RA being de-energized. Under fault conditions of a valve A, the potential at a point 3 falls causing the respective emitterbase junctions to be forward biased so that current flows from the emitter to the collector and energizes the relay winding RA to operate the relay which operates an alarm (not shown). The relay is provided with a bias winding RB which may have a constant energization, Fig. 1 (not shown), but to increase the sensitivity the bias may be reduced as the main winding RA is energized. Thus the bias winding RB may be connected to the collector of a further transistor J2 common to all the devices. The emitter of this transistor is connected to a constant current source I 1  and its base is connected to the common connection 2. The relay bias winding RB is normally energized, but on the occurrence of a fault, the potential at the connection 2 rises and the emitter-base junction of the transistor J2 is reverse biased so that the current in the bias winding RB falls as that in the main winding RA rises. In a modified arrangement, the transistors J are connected in parallel with the winding RA which is normally energized. In this case a transistor J partially short-circuits the winding RA to cause relay operation in the event of a fault, Fig. 4 (not shown). In other arrangements NPN transistors are used and respond to a rise in voltage at the point 3, Figs. 5 and 6 (not shown). To increase the speed of relay response, the transistors J may be arranged to trigger a flip-flop type of circuit connected between the transistors and the relay.
