Title: Testing apparatus for testing valves
IPC: G01M99/00
Filed: 1976-05-07
Abstract: An automatic test device for multipressure valves of differing design is specified, in which pneumatic pressures are applied to the valves which are to be tested in an automatic fashion with respect to their magnitude and duration. These pressures are measured using sensors (9) and compared with prescribed pressures in an error-evaluating device (5). Depending on the output signals of the error-evaluating device (5) and on time conditions prescribed by a timer (4) the pneumatic pressures are varied in accordance with the prescribed test conditions in order to carry out further test steps. The prescribed test conditions are stored in memories (3) the contents of which can be varied by manual data input (1). Given the occurrence of specific errors, test operation is halted and the type of error is printed out on a printer (8). The sensors (9) are automatically recalibrated at predetermined intervals. <IMAGE>

Abstract: 1,097,174. Pulse modulation circuits; inductive signalling. F. L. SMIDTH & CO. A/S. May 4, 1965, No. 18747/65. Headings H4L and H4U. [Also in Division G1] The temperature inside a rotating body is sensed by a temperature-sensitive resistor rotating with the body, and converted to a proportional mark-space ratio which is conveyed by inductive coupling to an external stationary receiver. As shown (Fig. 1), the rotating measuring circuit 2 is fed with A.C. from an external oscillator 8 coupled via coil 9 and conductive rings 3, 4 fixed to the rotating body. The A.C. voltage in circuit 2 is rectified and fed to a transistor multivibrator with temperaturesensitive resistor 1 in the base of one transistor, whereby it determines the mark-space ratio of the signal from the multivibrator. This is fed via output transformer 10 to the rings 3, 4 and picked up by stationary coil 5, connected to a circuit 6 which converts the signal for indication on a meter 7. In modifications: (a) the rotating body may itself constitute one of the conducting rings; (b) the transducer may be a strain gauge resistor. The invention may be applied to a rotary kiln, or a rotating cement grinding mill with automatic water injection control.

Abstract: 947,721. Testing radio apparatus. McMICHAEL RADIO Ltd. Aug. 29, 1960 [June 2, 1959], No. 18790/59. Heading H4L. [Also in Division G1] In a transmission system with two channels carrying signals whose relative amplitude is significant, test signals of predetermined relative amplitude are intermittently applied to the inputs of the channels and the outputs are compared. The Figures show a system for transmitting the readings of a flux-gate compass over a radio link. In the transmitter (Fig. 1) the exciting coil 13 is fed from a 400 c/s. oscillator 14 and the second-harmonic outputs from the pick-up coils 11 and 12 are passed through filters 17 and amplifiers 18 to frequencymodulate sub-carrier oscillators 19 operating at different frequencies, e.g. 16.5 kc/s. and 35.5 kc/s. A reference phase is obtained by frequency-doubling the output of the oscillator at 15 and using it to frequency-modulate a third 7 kc/s. sub-carrier oscillator 27. The three sub-carriers are used to frequency-modulate a further oscillator 29 whose output is radiated. At the receiver (Fig. 2) the carrier is demodulated and the three sub-carriers separated by filters 31, 40 and 46 before being demodulated, filtered and amplified in three separate channels. The two signals from the compass coils are passed to the coils 38 and 39 of a resolver whose rotor 51 is turned by a motor 52. The reference signal is applied to an amplifier 50 where it is compared with the signal induced in the rotor 51, and any difference energizes the motor 52 to position the rotor for zero error signal. The compass reading is obtained by a pointer on the rotor shaft and can be transmitted to remote indicators by a synchro 58. To monitor the gain-equality of the two signal channels, the output from the oscillator 14 is periodically switched into these channels by means of a 20 c/s. multivibrator 53 operating high-speed relays or electronic switches 16. Similar switches 36 and 45 in the receiver pass the outputs of the channels to a null detector 54 whose output (normally zero) can operate a visual indicator or adjust the gain of one channel. Synchronism between the switches in the transmitter and receiver is achieved by amplitude-modulating the oscillator signal at unit 26 in the transmitter, and picking this off in the receiver by a rectifier and integrator 56 to operate the switches 36 and 45. The integrated voltage also controls a blanking-pulse generator 57 to open-circuit the two signal channels during the change-over, thus preventing cross-talk. According to the Provisional Specification, the frequency-doubler 15 can be in the receiver instead of the transmitter, and the checking signal is taken from one of the coils 11 or 12 instead of the oscillator. Different frequencies are quoted for the sub-carrier oscillators.
