Filed: 1967-03-03
Abstract: 1,140,996. Boring earth &c. MOBIL OIL CORP. 3 March, 1967, No. 10183/67. Heading E1F. A  borehole is formed .by generating acoustic pulses in drilling fluid interposed between the bottom of .the hole and the drill. The pulses are generated by a plate 34 reciprocated relative to the drill string 12 by mechanism driven by a turbine 14 or an electric motor, by a magnetostrictive device, or by a jet-edge 'generator. The plate may be smaller than and eccentric of a skirt 40, the plate moving in a closed arcuate path during drilling. The plate which may be stainless steel or titanium is spaced from the hole bottom 'by a distance ranging from 2 m.m. to 2,borehole diameters; and the spacing is held by a pressure sensor or by fingers depending from the plate. The frequency of the pulses may be high enough to cause cavitation of the fluid which may be sufficiently dense so that debris fro mdrilling floats upwardly to be entrained by a less dense drilling fluid which is supplied through the drill string The fluid may slowly circulate to entrain the debris which is finally removed from the borehole by faster flowing fluid above the plate. A shock absorber comprising .a neoprene sleeve in which a spring is embedded is inserted in the drill string. The first part of the borehole is bored by conventional methods;

Title: Thermal radiation sensors
IPC: G01J5/12
Filed: 1972-03-04
Abstract: 1381001 Thermoelectric devices SENSORS Inc 4 March 1972 10225/72 Heading H1K A thermoelectric device is formed on a support produced by treating one face of a blank to form from the material of the blank a composition in the form of a high strength electrically insulating layer and removing part of the blank material to leave an exposed portion of the layer as a thin film supported at its entire periphery by the remaining blank material. An Al blank is produced with a recess in one face and the opposite face is polished and then anodized to form a layer of amorphous Al 2 O 3 . The depth of the recess is then increased, e.g. by etching, until the blank takes the form of a ring 22 having a thin film of Al 2 O 3  bridging the aperture. Thermoelectric materials are then deposited to form a thermocouple having its hot junction 46 at the centre of the film over the aperture and its cold junction above the Al supporting ring 22 which acts as a heat sink. The thermocouple is provided with contact pads 49, 50 of Ag, Au or In to which Au leads 47, 48 are connected by soldering or conductive cement. The blank may be completely anodized, but the oxide at the base of the recess must then be removed by abrading or etching before the recess can be etched out. The thin film may be in the shape of a cone, Fig. 6 (not shown), the interior surface of which is coated with radiation absorbing material and the hot junctions of a thermopile are deposited on the outer surface of the cone. A plurality of overlapping limbs of thermoelectric material may be deposited on the substrate to form a thermopile and the hot junctions may be covered with a radiation absorbing layer of lamp black. A radiation sensitive device may be mounted in a T05 type housing, having a transparent window in its cap, which may be evacuated or filled with Ar. The thermoelectric materials may be Bi, Sb, BiTe, PbTe or PbSe and may be applied to vacuum evaporation. The film may also be of Al 2 O 3 , AlN or Ta 2 O 3  produced by plasma anodizing Al or Ta blanks or of SiO 2  or Si 3 N 4  produced by thermally oxidizing or by chemical reaction with the surface of a Si blank. Al alloys may be used for the blank.

Title: Improvements in or relating to circuit arrangements for a transmission system, for example, a carrier wave telephony system
IPC: H04B17/40
Filed: 1963-03-15
Abstract: 1,012,462. Unattended repeaters. PHILIPS ELECTRONICS & ASSOCIATED INDUSTRIES Ltd. March 15, 1963 [March 20, 1962], No. 10381/63. Heading H4R. For the location of a faulty repeater in a carrier system, each repeater station includes an oscillator 4 for sending a signal to an indicator 7 at a terminal station, and the oscillators are controlled over an auxiliary line 9 which has Zener diodes 11, 14 in series and in parallel at each station so that as an increasing direct voltage is applied from a source 10 the oscillators are activated one at a time in succession. If, for example, in a one-way system, Fig. 1, the amplifier at VS3 is faulty, no indication is given until the oscillator at VS4 becomes operative. In a 2-way system, Fig. 2, the go and return paths are coupled as regards signal currents through an amplifier 15, so that high level signals are transmitted as long as the amplifiers in the go path are operating correctly. In order to reduce the direct voltage required for testing a large number of repeater stations, the line 9 is reversed between the stations, which are also provided with diodes 17, and the voltage is applied to the line over a change-over switch 16, so that half the oscillators are controlled in each position of the switch. A suitable transistor oscillator is described with reference to Fig. 3 (not shown).
