Abstract: 1,088,675. Radar and like systems. GENERAL ELECTRIC CO. Ltd. Dec. 16, 1964 [Dec. 16, 1963], No. 49569/63. Heading H4D. Relates to systems of the kind wherein an angle-modulated signal is transmitted and a counterpart thereof is mixed with the echo signal to afford a resultant signal which is range-dependent. According to the invention the transmitted signal is a carrier wave simultaneously angle-modulated at two different frequencies (# m , # r ) and range is computed from the resultant signal by means responsive to a relationship between selected parameters of two components of the resultant signal which are respectively attributable to the two modulations. In the embodiment the angle-modulation is F.M., the modulating signals (6, 7) are sinusoidal, the carrier is a radio wave, and the selected parameters are amplitudes; but the modulating signals may be sinusoidal, the carrier may be a sound wave and the selected parameters may be phases. The envelope of the output of adding circuit 8 is detected (9) (see also Fig. 3 (not shown)) and an amplifier 10 has its gain controlled by a peak detector 11; the output of a high-pass filter 12 is fed to a D.C. voltmeter 14, indicating range, via a peak detector 13.

Abstract: In order to prepare stable, aqueous emulsions of water-insoluble substances having low to medium viscosities, i.e. such having dynamic viscosities at temperatures between 15 and 32 DEG C of from 20 to 10,000 cP, a mixture of from 2 to 30% by weight of emulsifier - based on water-insoluble substance - and from 2 to 25% by weight of water - based on water-insoluble substance - is introduced as an initial charge. It is essential at this point that the amount of water is from 0.4 to 1.7 times the amount of emulsifier. The water-insoluble substance or the mixture of such substances is now slowly added stepwise, and the mixture during the addition of the water-insoluble substance or substances is subjected to shearing forces. It is possible in the process to prepare, in a first stage, a pre-emulsion from part of the water-insoluble substance and the entire remaining components of the mixture, and then to admix, in a second stage, the remainder of the water-insoluble substance.

Abstract: 1483268 Automatic control systems XEROX CORP 22 Nov 1974 [14 Dec 1973] 50648/74 Heading G3R In a web transport system, a web is moved from a supply reel to a take-up reel and each reel is driven by a motor. The current to a first motor is measured, and compared with a reference value and the difference applied to the other motor so as to tension the web and thus regulate the torque of the first (take-up reel drive) motor. In the embodiment a web driven encoder 30 provides a signal whose frequency depends upon the web speed. This signal passes through one-shot multi-vibrator 34 and low pass filter-shaper 36 to form a speed dependent voltage. This is compared with a speed reference Vo, any difference being amplified and used to vary the current I to D.C. motor 18 that drives the web take-up reel 12, and thus to regulate the web speed. The motor current I, which is proportional to the torque of motor 18, is measured using resistor 40 and compared at 42 with a reference value. Any error after amplification and inversion energizes D.C. motor 16 driving supply reel 10, to reverse bias the motor and tension the web. This regulates the current, and thus the output torque, of motor 18, which torque is then independent of the web radius on the take-up reel. The web may be magnetic tape, micro-film or paper.

Abstract: 1328224 Packaging articles in bags W R GRACE & CO 28 Oct 1970 [24 Nov 1969] 51287/70 Heading B8C Apparatus for opening a bag in a pre-determined position comprises a blower 120, Fig. 2, having an outlet for directing a stream of air across the opening of a bag located in the predetermined position, an air delivery passageway at the outlet of the blower and means movable into the passageway for constricting the passageway to a variable extent. As shown, a string of bags is pulled from a box 26 over rollers 22a, 22b, 22c on to a table 30, Fig. 3, where each bag is opened by a stream of air prior to filling by hand. The bags are interconnected by a pair of adhesive coated tapes 35, 36, Fig. 5, from which the bags are detached by hand as the leading end of the tapes are pulled down and fed one on each side of guides 40, 41, stuck together and fed between gear-wheels 42, 43 and through an aspirator opening 113 and channel 112 and back to the box 26. The table 30 forms part of a removable assembly 46 which includes a motor 63 driving the wheel 42 which is controlled by an air jet signalling means 53, controlling the sequential advance of the bags. When the jet 53 is blocked by the lead bag, the air pressure operates a switch 62 which switches off the motor 63. An override switch 72 operates to switch off the motor if a bag over-rides the jet 53 and engages a rod 37 positioned in a cutout at the forward edge of the table 30. The wheel 43 is loaded into engagement with wheel 42 by an air cylinder 83 against spring means. The aspirator 44 is shut off each time the motor 62 is stopped. The blower 120 delivers air to an air delivery shoot 126 which directs air across the forward edge of table 30 to inflate the leading bag thereon. Drawers 132a, 132b, Fig. 1, are slidably adjustable in side walls 130a, 130b to constrict the width of the shoot in accordance with the size of bags being opened. A damper plate 134 is also positioned to partially block the air inlet to the blower 120. Articles to be inserted in the bags are positioned on a carriage 144 at a loading station 162. The carriage is then propelled by an air cylinder 167 to an inserting position 163, upon actuation by an operator of a hinged plate 164 extending substantially the length of the machine and controlling the actuation of a valve 165 which controls the cylinder 167 and also a similar cylinder which propels the carriage from the inserting position back to the loading position 167. The machine is adjustable to handle bags of different sizes by adjustment of guides 40, 41 and drawers 132a, 132b. Specifications 1,328,225 and 1,328,226 are referred to.

Abstract: 1,075,080. Ultrasonic flaw-detection. J. OBRAZ. Dec. 17, 1964 [Jan. 14, 1964], No. 51381/64. Heading H4D. In a pulse-echo ultrasonic flaw-detector, changes in the acoustic coupling between a transmitting/receiving transducer and the workpiece are automatically compensated for by a circuit in which selected echo signals resulting from a transmitted acoustic pulse are summed on a capacitor to provide a control voltage for varying the amplitude of the next transmitted pulse. In the embodiment of Figs. 1 and 3 (not shown) an ultrasonic transmitter (2) is triggered at time t 1  by the trailing edge of a pulse of a waveform a produced by a signal generator (6). The resulting signal, b, from a receiver (3) comprises the transmission pulse t 1  and echo pulses t 3 , t 4  e.g. from a flaw and from the back surface of the workpiece respectively. The receiver signal b is applied to a pulse amplifier (14) which is gated by a waveform c, generated by the signal generator (6) and comprising pulses of variable delay t 1 -t 2  and variable duration t 2 -t 5 , such that selected echo pulses are fed to a storage capacitor (C) on which they are summed. Capacitor (C) is discharged through a valve (15) at the instant to before each ultrasonic transmission. The resulting voltage waveform d at capacitor (C) is fed through a cathode follower (16) to a summing circuit (8) in which it is shaped by a network (R 1 C 1 D 1 ) to give a waveform e which is then algebraically summed with a waveform f applied to a capacitor (C 2 ) by the signal generator (6). The resultant waveform, g, is fed through an amplifying stage (9) to the screen grid of a valve in the transmitter circuit. The arrangement is such that the potential applied to the screen grid in the interval t 0 -t 2  (and therefore at the instant of transmission, t 1 ) is representative of the amplitudes of the selected echoes from the previous transmission, the transmitter power output being increased if the echo amplitude was low (i.e. due to poor acoustic coupling) and decreased if the echo amplitude was high. The receiver waveform b is displayed on a cathoderay oscilloscope, and the gating waveform c is also displayed for monitoring the selection of the echo pulses.
