Title: Improved grab for recovering lost articles from bore holes
IPC: E21B31/18
Filed: 1926-02-22
Abstract: 262,632. Hinderliter, F. J. Feb. 22, 1926. Borehole apparatus.-A fisl ing tool for recovering lost articles from boreholes comprises an offset spud 16 extending below a gripping lever 20 so as to strike against the object 13 and bring it to an erect position. The lever 20 is pivoted at 22 in a recess in the shank. In operation, the device is lowered through the casing 10, 11 and the offset spud then swings clear of the casing and lies close to the wall of the hole. The gripping lever 20 is held away from the spud by a pin 26. When the tool strikes the object 13, the pin is fractured and the grip is closed by springs 23. The spud may be semi-circular in crosssection and provided with sexrated slips 17 sliding in inclined grooves to grip circular objects by a wedging action.

Title: Improvements in or relating to fire alarm apparatus

IPC: G08B19/00
Filed: 1956-02-20
Abstract: 855,707. Fire alarms; electric. PYRENE CO. Ltd. Feb. 20, 1957 [Feb. 20, 1956], No. 5202/56. Class 118 (1). A fire detector of the kind having detector heads each comprising two resistances a, b, differently affected by temperature and connected in series respectively with the resistances a, b of other heads, the two series circuits being connected in parallel and joined to a source of power and an alarm device, is so adjusted that when one or more heads become heated then the resistances of the elements a of the head or heads will increase more than that of elements b and cause the alarm device to operate and indicate the warning either locally or at a central station. In such a kind, two points 1, 3, separated by a part, the whole of, or more than one resistance a are connected through high resistances rl, r2, r3, r4, which need not be equal, to the other parallel circuit at points 2, 4 (in the preferred case cross connected as shown). A galvanometer is connected between the transverse con-  nections as shown, so that if the ratio of the currents in the transverse connection alters, due to fire conditions, then current passes through the galvanometer to swing the needle across alarm contacts, which needle is then held magnetically. Fusible links c connected as shown, may break with fault conditions and so operate the galvanometer, and fault indicator lamps may form part of each detector head.  A suitable method of connecting the heads to the alarm device is shown in Specification 632,279.

Abstract: 713,040. Electromagnetic switches. ESMENARD, E. March 3, 1952 [March 8, 1951], No. 5555/52.

Abstract: 743,403. Television. BRITISH BROADCASTING CORPORATION. March 10, 1952 [March 8, 1951], No. 5674/51. Class 40 (3). [Also in Group XL (c)] The Figure shows a circuit in which the signal from a television camera 10 is caused to assume a predetermined and adjustable datum level in the interval between line scans the occurrence time of which is determined by positive pulses supplied from generator 22. In the intervals between pulses from generator 22 valves 11 and 12 which have similar characteristics, are conducting and the signal output from camera 10 is applied, by virtue of cathode resistor 13, in push-pull to their control grids the anti-phase outputs from the anode loads 20, 21 being applied directly to the control grids of a further pair of valves 23, 24. As the signal voltages at the control grids of valves 23, 24 are in antiphase there is no effective negative feedback across the common cathode resistor 25 and an output voltage may be taken at either or both of terminals 34, 35. When a positive pulse is applied from generator 22 both valves 11 and 12 are rendered non-conductive so that the potential difference between their anodes is substantially zero thus providing a predetermined datum level. This datum voltage is in phase at the anodes of valves 11 and 12 and as resistor 25 provides a considerable degree of negative feedback the switching pulse from generator 22 appears at the outputs 34, 35 only at a low amplitude and may be eliminated from one output entirely by adjustment of resistor 18. If the switching level is required to provide a datum level at either of the outputs 34, 35 its amplitude may be adjusted by variation of resistor 18.

Title: Improvements in thermionic valve voltmeter arrangements and their application to measurements on electrical circuits
IPC: G01R27/28
Filed: 1942-05-01
Abstract: 554,959. Voltage measurements. STANDARD TELEHONES & CABLES, Ltd. May 1, 1942, No. 5888. Convention date, April 25, 1941. [Class 37] In a thermionic-valve voltmeter arrangement for measuring on site the voltages on a transducer unbalanced with respect to earth potential, the effects of temperature and humidity changes of ageing, and supply-voltage irregularities, are neutralized by providing a pair of thermionic valve devices balanced with respect to earth potential and measuring the voltage-difference between two of their terminals, such difference representing the magnitude of the voltage on the transducer at that point. Figs, 1, 2 show an arrangement for measuring the gain characteristic of a coaxial-conductor line 10 having a repeater 9, over a range of frequencies, say 50-3500 kc., supplied by an oscillator 11 and the outer conductor being earthed at both ends. Thermionic-valve voltmeters 20, 21 are located at the input and output of line 10 which also includes a variable attenuator 13. The voltmeters 20, 21 are both as shown in Fig. 2, each comprising a doublediode rectifier 30 having one 'anode-cathode circuit 31, 34 connected to lead 22, and the other 40, 44 to lead 23. The voltage across resistance 36 is fed to the grid of an amplifier 59, the cathodecircuit of which includes a bias resistance. A similar amplifier 74 has its grid connected to resistance 46 and its cathode circuit includes a fixed and a variable resistance 75, 76. A meter 81 is connected to both cathodes at 62, 83 and is shunted by a variable resistance 84. In operation, an initial zeroizing of meter 81 is effected by adjusting resistance 76 with the oscillator 11 disconnected, thus making the amplifier-cathodes of equal potential. Oscillator 11, or another source, then supplies the voltmeters 20, 21 with a calibrating frequency within the test frequency range and of a given amplitude. The resistors 84 are adjusted to give the same pre-assigned reading on both meters 81, thus providing an amplitude calibration. Oscillator 11 then applies successive frequencies and in each case attenuator 13 is adjusted so as to restore the pre-assigned reading of meter 81 of the volt-meter 21. The sum of the readings of 20 and 13 is then a measure of the gain of the line. The amplifier 74 and other half of the diode provide initial balance and then effect the necessary compensation. Fig. 3 shows a differential voltmeter for a transducer having adjacent input and output terminals and an amplifier 100 the voltage across which is to be measured, each amplifier 59, 74 having its own rectifier 101, 102. The initial zero-reading of meter 81 is produced by cathode-resistance 103 and in subsequent tests, attenuator 13 is adjusted to restore the null-reading and its own setting shows the gain for the particular frequency.
