Abstract: 1283597 Air filtering system KAPPERS KLIMATECHNIK GmbH & CO KG and FRIED KRUPP GmbH 5 Dec 1969 [6 Dec 1968] 59602/69 Heading B1T [Also in Divisions B7 and F4] A mobile unit for supply air to an inflatable tent comprises a blower 9 which in normal operation draws air from the inlet 6 through filter 2, valves 8 and the chamber 10 and delivers it via conduit 12 to the distribution chamber 11. Air for inflating the tent is supplied via the conduit 13 whilst air for the tent interior is supplied via a heat exchanger 4 having a burner 17. Air is also supplied from the outlets 16 to maintain the interior of the substantially air-tight housing 5 above atmospheric pressure. When the outside atmosphere is contaminated the valves 8 are shut and air is drawn into the chamber 10 through the spherical filters 3 having external inlets 7. Control of the amount of air supplied to the tent interior is controlled by a throttle valve 22 provided in a recirculating pipe 23 connected between the heat exchanger 4 and the chamber 10.

Abstract: 1, 247, 542. Monitoring the curing of an elastomer. B. F. GOODRICH Co. Dec. 17, 1968 [Dec. 18, 19671 No. 59971/68. Headings G1N, G1S and G1U. Apparatus for monitoring the curing of an elastomer comprises means for measuring the torque on the shaft of a paddle oscillated in the elastomer during the airing process, and means for comparing this torque with predetermined limiting valves based on the known curing characteristics of the material. The elastomer material is located in a conical chamber 26 Fig. 1 in a member 25 fixed to the pistons 22 of two cylinders 20, mounted on a fixed bracket 13. A motor 40 is coupled via coupling 34, 35 to a plate 33 carrying a central shaft 31 terminating in a conical rotor 27 located in chamber 26. When the motor is energized it causes the rotor 27 to oscillate in the elastomeric material in chamber 26 which is being subjected to a standard curing programme. The degree of curing is measured by the torque in shaft 31, sensed by a strain gauge bridge transducer 43, and fed to a recorder 44. The latter is coupled to the slider 47 of a repeating potentiometer 151 Fig. 4, for automatic comparison of the torque value with upper and lower limiting values previously determined and set up on resistance banks 125, 127, using a punched cad which also detects the time of fed on a timer 140. The two voltage comparisons are made as Voltage Detector Units A, B and selectively operate lamps L1, L2, L3 in accordance with the comparisons.

Abstract: 680,843. Dividing by fusion. HUNT, Ltd., A. H. April 16, 1951 [June 26, 1950], No. 15924/50. Class 83 (iv). [Also in Group XXXVI] Relates to condensers of the kind disclosed in Specification 647,573, [Group XXXVI], in which a strip of di-electric material is metallized on one face, demetallized to leave a pattern as shown in Fig. 1, and then rolled. According to the present invention, the scale of the pattern is progressively increased by altering the relative speed between the movement of the di-electric strip and the demetallizing means. As shown, a fully metallized strip is led from a spool 39, Fig. 2, past a suitably profiled demetallizing wheel 27, and is wound into a condenser at 47 ; the shafts 50 and 26 are positively driven, so that as the wound condenser increases in diameter, the strip is pulled through more quickly and progressively increasing slip occurs between the wheel and the strip. The wheel demetallizes as disclosed in Specification 647,573, [Group XXXVI]. For large condensers, the drives may be arranged so that negative slip occurs at the beginning of the wind.

Title: Improved structural supporting arrangements for a multi- break live-tank circuit-breaker assemblage having improved voltage- distribution characteristics between the several series breaks
IPC: H01H33/915
Filed: 1979-05-11
Abstract: A multi-break circuit-interrupter assemblage has its voltage-division characteristics determined by having upstanding supporting column structures 15, 16 either disposed slantingly outwardly, in a somewhat diverging "V"-shaped relationship, or, alternatively, vertically-disposed, with the electrical bus-bar interconnection 8A located at the upper ends of the upstanding column structures, and the line-terminal connections 11, 12 therefor disposed part-way down each of the column structures, thus constituting thereby, a somewhat inverted "U"- shaped electrical current path due to the supporting arrangement. The specification also discloses a mounting support comprising an inverted "U"-shaped supporting construction, with the series multi- breaks disposed at the upper horizontal side of or "bight" portion of an inverted "U"-shaped supporting structure. Both arrangements are intended minimize the effects of inherent parasitic capacitance effects, which tend to lead to unequal voltage distribution between the several series breaks. <IMAGE>

Abstract: A fluid pressure operated engine comprises a cylinder 1, a piston 3, a crank 6 and driveshaft 5 and a distribution valve 12 which controls the admission of working fluid from a source 23 to each end of the cylinder. Valve 12 is reciprocated by the armature of an electromagnet 30 which is energised by an oscillator 28 which is manually adjusted by lever 29 to run at a frequency which is numerically equal to the desired rotational speed of the drive shaft 5.

The difference of electrical signals from oscillator 28 and contact 43 is amplified by operational amplifier 56. A further operational amplifier 64 and switch 65 is used to reverse the polarity of the oscillator signal in order to reverse the engine. <IMAGE>

Title: Microelectronic circuit and method of manufacture
IPC: H01F41/34
Filed: 1979-07-26
Abstract: In a magnetic bubble domain circuit, a conductive layer 13 on a garnet substrate 10 is etched to form conductor patterns. The grooves through the layer 13 are filled with an insulating material, e.g. a glass, 21, 22, 23, to provide a flat surface. Therefore when an insulating layer and patterned permalloy overlay 25 are subsequently provided, there are no steps in the overlay. This eliminates a source of defects and the uniform spacing of the overlay from the substrate results in better operating characteristics. The same technique, employing a flat surface, can be used in semiconductor circuits. <IMAGE>
Patent GB-2057531-A (GB)
Title: Measuring while drilling tool
IPC: E21B47/18
Filed: 1979-08-30
Abstract: A measuring while drilling tool includes a closed circuit hydraulic system which is energised by variations in mud pressure and serves to modulate mud back pressure to provide surface signals indicative of well parameters. The hydraulic system includes a low pressure reservoir (215) from which five transducers are charged with fluid via a fill valve (147). The volume of fluid needed to charge each transducer is dependent on the value of the parameter detected by each transducer. Each transducer is provided with a detent valve, the detent valves being connected to a common manifold (150) and being operated in sequence by an enlargement (127) on the rod (126) of a hydraulic ram (124). When a particular detent valve is opened by the enlargement (127) the fluid contained in the associated transducer is dumped into the common manifold (150) and controls a hydraulic ram via lines (185, 200) whereby the flow area of a mud flow orifice is restricted for a period of time proportional to the volume of fluid in the particular transducer. Parameters detected may include tool inclination and magnetic heading. <IMAGE>

Title: Determination of water saturation adjacent well boreholes
IPC: G01N23/222
Filed: 1979-10-26
Abstract: Gamma ray spectra of earth formations surrounding a well borehole are obtained by bombarding the formations with neutrons from a pulsed neutron source 22 and detecting the gamma rays resulting from capture of thermalized neutrons in the formation using a germanium gamma ray detector 28. A measure of the ratio of chlorine to hydrogen is obtained by integrating areas under selected capture peaks of chlorine and hydrogen after subtracting the continuum from the spectra, and forming the ratio of the areas. The apparent formation water salinity is determined from the chlorine/hydrogen ratio. The water saturation of the formation is then obtained from the apparent formation water salinity and the true formation water salinity. Compensation is made for the presence of saline water in the borehole fluid and in the cement annulus, as well as for any bound water in the formation. <IMAGE>
