Title: Pulse-echo system
IPC: G01S1/72
Filed: 1955-06-14
Abstract: 801,461. Echo distance-measuring. CLEVITE CORPORATION. June 14, 1955 [June 15, 1954], No. 17079/55. Class 118 (2). An underwater pulse-echo system comprises in combination underwater acoustic transducer means for transmitting an abrupt acoustic signal pulse and for receiving signal echoes, a receiver circuit connected to the transducer means to respond to signal echoes received thereby, time variable-gain amplifier means connected to the transducer means and operative to reduce the gain of signal echoes received initially and increase the gain of later-received signal echoes, and a differentiator in the receiver circuit capable of passing abrupt signal echoes and rejecting echoes of slowly changing amplitude. The transmitted pulse 12 produces various reflections from the water surface, from particles in the water, and from the sea bottom. The sum total of these discrete pulses from progressively distant reflections results in a slowly decaying reverberation signal 13 which tends to obscure a target echo such as 14. The differentiating circuit separates the slowly decaying signal 13 and abrupt signal 14 whilst the use of swept gain prevents the initial steep front of the reverberation 13 from producing an output signal.

Title: Apparatus for the processing of value systems whose units are connected to one another non-decadically in data-processing machines which serve for the processing of value systems whose units are connected to one another decadically
IPC: H03M7/08
Filed: 1964-04-24
Abstract: 1,057,193. Digital electric computer. SIEMAG FEINMECHANISCHE WERKE G.m.b.H. April 24, 1964 [April 25, 1963], No. 17177/64. Heading G4A. Digital electrical calculating apparatus for multiplying decimal non-decadic data such as sterling by specified digits comprises an input unit 1 connected by two alternatively switched paths to a store 3, one path being a direct transmission path and the other containing a decimal non-decadic to decimal decadic conversion unit, data in units such as pounds being transmitted in the direct line and the other data being converted to a decimal, and the decimal value being rounded off to two figures. The store 3 is connected by two alternatively switched paths to a calculation mechanism 6. One path is a direct transmission path, the other contains a unit 4 multiplying by a correction unit. The correction unit serves to correct for the error produced in rounding off the decimal and is found by factorizing the number expressing the relation between the highest and lowest units of the decimal non- decadic code, i.e. 240 for sterling, taking a factor other than 2 or 5 and using as the correction unit a multiple of this factor. For sterling 240 = 3 x 2<4> x 5 thus 3 or 6 is preferably used. The number is multiplied in unit 4 and rounded off in its last place and stored in unit 5. The complete number is multiplied by the specified digits in unit 6 and stored in unit 7 and then fed to unit 8 where it is divided by the correction factor, then the whole number portion is fed directly to the output unit 10 and the decimal portion fed to unit 9 which converts back to the decimal non-decadic system and thence is fed to the output. The switches may be manuallyoperated and the conversion means may have the decimal equivalent of each value of the non-decadic denomination stored therein.

Patent GB-1508774-A (GB)
Title: Apparatus for testing voltage regulators
IPC: H02J7/16
Filed: 1974-04-20
Abstract: 1508774 Testing electrical apparatus LUCAS ELECTRICAL Ltd 14 April 1975 [20 April 1974] 17430/74 Heading G1U In testing a voltage regulator, an increasing voltage is supplied thereto and at the operating point, when a semi-conductor switch in the regulator turns off, a switch in the test apparatus prevents further rise in the voltage which is indicated. The automobile voltage regulator, Fig. 1 (not shown), has three terminals +, -, F, normally connected to an alternator. These are connected to terminals 11a, 12a, 13a in the test apparatus. If the voltage supplied to the regulator at terminal 11a is below its operating point, terminals 12a, 13a are connected together through a transistor (19) in the regulator. Thus, transistors 27, 28 are off, allowing capacitor 29 to charge towards the voltage (45 volts) or line 23 derived from an A.C. rectified supply 25, 26, 20. At the switching voltage, the path from 12a to 13a is opened and the regulator oscillates providing a current through resistor 36 (simulating the alternator field winding) to turn on transistor 27, 28 allowing the capacitor 29 to discharge and causing the voltage at terminal 11a to fall. Thus the voltage supplied to the regulator oscillates about a mean level close to the operating voltage of the transistor switch (19) in the regulator. This voltage is passed to a meter 45 which because of its inertia, indicates the mean level. Zener diode 52 has a 15 volt threshold, thus if a correctly operating 12 volt regulator is being tested, the diode remains non-conducting, ensuring that transistors 55, 56 are off. In this state base current for transistor 61 flows through lamp 58 (which does not glow at such a low current) and the transistor turns on, breaking down the 12 volt Zener diode 46 and turning on transistor 43. The regulator voltage is thus transferred to the meter 45 via transistor 61, diode 46 and transistor 43 with a 12 volt back-off. Adjustment of resistor 47 calibrates the meter. If a 24 volt regulator is tested, the voltage at terminal 11a rises above the breakdown voltage of Zener diode 52 and the transistors 55, 56 are turned on, illuminating the lamp 58 and turning off transistor 61. A second 12 volt Zener diode 41 is now introduced between the meter 45 and the terminal 11a, providing a total 24 volt back-off. Resistor 42 is used to calibrate in this case. The meter 45 thus is required to indicate only the excess of the operating voltage above the nominal values 12 volts or 24 volts and consequently measures the same order of voltage in both cases, ensuring similar sensitivity.

Filed: 1934-06-13
Abstract: 438,064. Thermal switches. HALL, Ltd., J. & E., 10, St. Swithin's Lane, London, and BRAIN, C. M., Dartford Ironworks, Dartford, Kent. June 13, 1934, No. 17472. [Class 38 (v)] [See also Group XIII] A thermal switch controlling the circuits to heating and refrigerating apparatus in accordance with the temperature of a liquid has means influenced by the surrounding air whereby the temperature limits within which the switch operates are varied. The bulb 14 containing methyl chloride is immersed in the liquid and controls the expansion and contraction of a bellows 10 which acts against a spring 13 upon a lever 9 tilting mercury switches 1, 2 in the circuits of the heating and refrigerating means respectively. The normal temperature limits may be adjusted by a knob 27 which changes the pressures of the spring 13, and also by adjustment of a disc 22. According to the invention a bellows 19 subject to the temperature of the air actuates a lever 16 against a spring 21 so that its position depends on air temperature and, through a spring connection 17 to the lever 9 causes the refrigerating apparatus to be energized at a higher water temperature than normal and the heating apparatus to be energized at a lower temperature than normal.
