IPC: E21B47/10
Filed: 1970-02-11
Abstract: 1304702 Measuring fluid flow electrically SOC DE PROSPECTION ELECTRIQUE SCHLUMBERGER 11 Feb 1970 [6 March 1969 6649/70 Heading G1N [Also in Division F1] A fluid flowmeter for studying flow in boreholes comprises a screw impeller 23 having foldable blades 87, a mechanism for folding the blades to permit the flowmeter to pass through strictures, and a shaft 67 having ferromagnetic parts 74, 75 responsive to the magnetic fields from respective coils 67, 73 so as to provide an electromagnetic suspension for the impeller, rotation of which causes repetitive closures of a magnetic reed relay 84 to produce electric signals of which the frequency represents rotary speed of the impeller. In use the flowmeter is drawn up through a casing 13 in a borehole 11 when coils 67, 73 are energized as is solenoid 53 to open valve 51. Flattening of bow springs 33 by a restriction urges sliding ring 34 and piston 37 to compress hydraulic fluid in chamber 43 communicating via passage 46 and valve 51 with chamber 48 to urge pistons 60 and 64 downwardly into engagement with shaft 67. Consequential downward movement of hub 85 causes at 86 pivoting of impeller blades 87 when the downward movement of rod 92 is halted by abutment of stop 96 on sleeve 93 against shoulder 98 of body 30. The voltage, Fig.4, (not shown), applied to the coils includes a d. c. component, a V.L.F.a.c. component and a 60Hz.a.c. component so that the shaft performs reciprocatory motions along its axis. In an alternative embodiment, Fig.5-7 (not shown), the impeller has eight blades, in two sets of four spaced apart axially of the shaft and displaced angularly by 45. The sets fold by pivoting in opposed angular directions so that for a given flow direction the resultant force exerted on the blades by the flowing fluid and tending to close the blades is substantially zero. In another embodiment folding of the blades is by an electrically actuated pump controling fluid pressure in the passage 46, when the piston is eliminated.

Abstract: 367,203. Elastic diaphragm pressure gauges. WATSON, F., 43, Southampton Buildings, London.-(Aktiebolaget Nautiska Apparater ; 28, Sveavagen, Stockholm.) March 10, 1931, No. 7366. [Class 106 (ii).] Relates to the type having a resilient member moved by the differential pressure to be measured, a chamber having a casing which includes a resilient element, a conduit connecting the chamber to a source of fluid pressure, gauges connected to said chamber, and separate valves controlling the passage of fluid between the chamber and the conduit and the atmosphere respectively, and consists in providing a valve to control passage of fluid from the conduit to the chamber, and a valve controlling passage of fluid from the chamber to the atmosphere arranged one on each side of the chamber and on a common spindle controlled by the resilient member. The high and low pressure pipes of a Pitot tube device are connected to chambers 13, 14 on each side of a flexible diaphragm 12. Passing at right-angles through the centre of the diaphragm is a bolt 34 surrounded by sleeves 39, 40 between the diaphragm 12 and two stiff diaphragms 37, 38 and serving to clamp these parts together. The parts 37, 38 are clamped at the edge to the castings forming the chambers 13, 14 by caps 32, 33. An adjustable extension 46 of the bolt 34 engages the central hood part 75 of a flexible diaphragm 52 similar to the diaphragm 12 and clamped at the periphery between a ring 51 and casting 49. A stiff diaphragm 66 is clamped between the casting 49 and a cap 62 provided with a connection for a pipe 64 supplying an auxiliary pressure fluid. A rod 70 carrying two valves 69, 71 passes through the diaphragms 66, 52, the valves being kept on their seatings by a spring 78. A pressure gauge is connected by a pipe 59 to the chamber 58. When the diaphragm 12 is moved to the right by the pressure difference to be measured the end 46 of the rod 34 moves the diaphragm 52 to the right and the valve 69 is opened to admit pressure fluid to the chamber 58. The movement of the diaphragm 12 is then neutralized and the pressure difference read on the gauge connected to the pipe 59. If now this pressure-difference falls, the diaphragm 52 moves to the left and the valve 71 is opened to vent fluid to the atmosphere through holes in the hand 75 until a balance is regained.

Abstract: 746,422. Conveyers. OHRNELL, O. March 15, 1954 [March 14, 1953], No. 7478/54. Class 78 (1). In a process of manufacture wherein operators are situated at various stations at the sides of a conveyer track along which boxes, containing parts necessary in the manufacture are conveyed to the different stations, the boxes are stopped automatically opposite their appropriate stations by stops arranged at different heights above the conveyer track at the work stations, each of which stops co-operates with an abutment on a particular box, which abutment is adjustable into different height positions on the box. In Figs. 1, 2, 4 the upper and lower runs of an endless belt convey the boxes 3 to working stations I-VI at each of which is arranged a machine 4 with associated seat 5 for an operator. Tables 8, 9 arranged along the sides of the conveyer for receiving boxes stopped at the stations are formed with gaps 10 in which operate elevator platforms 11 for carrying the boxes from the upper to the lower tables. Stops 12 mounted at the side of the conveyer co-operate with abutments on the boxes, each abutment comprising a plug mounted in one of a series of holes 14 at a height corresponding with the height of the appropriate stop. In the embodiment shown in Figs. 5, 6 the stops 12a are adjustably mounted by bolts 23 in slots 21 in uprights 22. Alternatively, the uprights may be provided with holes which register with the holes for the abutments 13 on the boxes. The stops 12a may be slotted or provided with more holes such as 24 to enable it to be adjusted laterally. If a box cannot be received at a work station on the upper run, it may be allowed to continue to the end of the run and transferred by a roller track to the lower run which returns it to the work station where it is retained by stops disposed at the same height as on the upper run. The box is allowed to continue along the'upper run by lifting the belt so that the abutments 13 on the box pass above the stops 12a. This is effected by depressing a lever 18 whereby a portion 20 of a metal sheet 16 pivoted to the conveyer support 17 extends upwardly through a slot 19 in the support to raise the belt. The conveyer may comprise a roller track.
