Title: Downhole motor for driving a tool
IPC: F01C1/10
Filed: 1974-09-03
Abstract: 1482574 Rotary positive displacement machines W TIRASPOLSKY and R F ROUVIERE 3 Sept 1974 [3 Sept 1973] 38529/74 Heading F1F [Also in Division E1] A downhole fluid motor for driving an earth boring tool includes an outer casing which is adapted for connection at its upper end to a drill stem and which accommodates a tubular body and a shaft having intermeshing helical teeth between which the drilling fluid passes to cause rotation of the body and a boring tool carried thereby, the body having one more tooth than the shaft which is secured against rotation relative to the casing but free to nutate. The body is supported for rotation by upper and lower radial bearings, and at least a portion of the teeth is located between the bearings. In the Fig. 1 embodiment, body 1 is connectable to a drilling tool via sub 3 and is suspended from a coupling sleeve 15 supported by a sub 20 via bearings 16 associated with springs 21, 22 which allow sub 20 to come into direct abutment with a ring 17 on the sleeve 15. The sub 20 connects motor casing 4 to a seal sub 24 incorporating a fitting 25, for subjecting the motor lubricant to ambient pressure, and ports 29 allowing drilling fluid leaking past upper seal 27 to pass to the borehole. The lubricant is retained in the motor by seal 26 in sub 24 and seal 8 in a lower bearing 7. The motor shaft 2 is suspended by a cardan shaft supported in universal joints 13, 14 and has a bypass passage closed by a fitting containing a valve 11 and a fixed restrictor 12. The motor may include two stages, the lower motor shaft being suspended from the upper by a cardan shaft Fig. 2, (not shown). In the Fig. 3 embodiment, the motor shaft 115 receives bayonet fitting plug 117 incorporating the by-pass valve and nozzle, and a lubricant reservoir 131 is provided whose outer flexible wall is exposed to ambient pressure. The body 101 in this case is connected to a drilling tool connector sub 106 via extension sub 104, having a hexagonal bore 114 allowing it to be restrained against rotation during connection to sub 106. The lower bearing 109 on the motor casing 130 is grooved interiorly to pressurize the bearing inboard of seal ring 112. In other embodiments, the bearings may be lubricated by drilling fluid.

Abstract: 894,028. Automatic volume control. STANDARD TELEPHONES & CABLES Ltd. Nov. 11, 1960, No. 38877/60. Drawings to Specification. Class 40 (4). [Also in Group XL (c)] An amplifier comprising a tunnel diode biased to a point on the negative resistance part of its characteristic, has gain-control means controlled from its output. The control signal may be derived from a pilot current injected into the amplifier input, or may be the signal itself together with the noise associated with the signal channel. The control signal may change the value of a resistance in shunt with tunnel diode. The control signal may control this resistance mechanically; or the resistance may be a semi-conductor diode controlled by the rectified control signal; or the resistance may be a thermistor controlled by the control signal itself. Alternatively the control signal may change the bias on the tunnel diode.

Abstract: 1,088,809. Automatic voltage control. STANDARD TELEPHONES & CABLES Ltd. Sept.2, 1966 [Sept. 2, 1965], No.39315/66. Heading G3R. A load 9a is supplied from an A. C. source by way of an auto-transformer the winding of which is associated as shown with a controllable impedance constituted by a tuned circuit 5a, 6a and controlled rectifiers 7a, 8a. When the rectifiers are triggered to conduct continuously the tuned circuit is short-circuited so that the controllable impedance is zero and the load has the maximum percentage of the A. C. supply voltage applied across it; as the rectifiers are triggered later in the voltage cycle oscillatory currents build up in the tuned circuit with the result that the effective impedance and voltage across the controllable impedance increase and the output voltage decreases. The circuit 10a for the controlled rectifiers 7a, 8a produces triggering pulses in dependence upon output voltage variations, whereby the voltage across the load is maintained constant, and a suitable arrangement for the triggering circuit is described with reference to Fig. 3 (not shown).

Patent GB-412675-A (GB)
Abstract: 412,675. Totalizators. HANDLEY, J., SUCKLING, C., 22, Sandringham Road, and SUCKLING, R. H., 19, Heather Gardens, both in Golders Green, London. Feb. 9, 1933, No. 4046. [Class 106 (i).] In an electric totalizator in which bets made at different ticket-issuing machines are counted in succession under the control of a rotary commutator, the battery connection to the commutator for effecting the counting operations is made over wipers of three step-by-step switches (or equivalent relay sets) which must all be in the same position before counting can proceed and which are operated at each counting-operation by impulses transmitted respectively from a release magnet at the ticket machine, an individual counting magnet, and a total-counting magnet. Assuming that the second pair of contacts 24 has been closed at the 2/- machine 1, when the commutator 11 connects battery 43 over brush 45 to lead 14, magnet 16 operates causing escapement 26 to lower arm 33 so that contacts 71 are closed. Battery 68 is thus connected to release-magnet 17 which withdraws a locking armature 28, and over closed contacts 24 to individual counter 3 and total counter 4. Magnets 17, 3, 4, transmit impulses to the magnets 19, 21, 23, of three checking switches the wipers 35 .. 38 of which only connect battery 43 to brush 45 when they are in corresponding positions. If this synchronism is not maintained, normally-energized relay 46 releases opening its locking contacts 47 and closing contacts 48 to connect up signalling battery 49 which (1) operates relay 51 to connect ground to lamps 63, (2) operates a relay 56 individual to the ticket-machine concerned over a second commutator brush 55, and (3) lights lamps 42 over wipers 39 .. 41 to indicate the positions of the checking switches. Relay 56 lights a lamp 58 individual to the ticket-machine and extends the battery 49 over lead 61 and contacts 24 to complete the circuit of one of the lamps 63. To restart the system, key 64 is operated connecting battery over an intermediate (shaded) commutator segment to operate relay 46. Any machine may be disconnected by operating a key 66 connecting the corresponding lead from the commutator to a resistance 65 which is also connected to the intermediate (shaded) segments to prevent sparking. At a 10/- ticket machine 2, five sets of contacts 71 are provided and five impulses are transmitted over lead 15 from the commutator. When the counting is completed, arm 33 closes contacts 32 and magnet 16 is subsequently operated over a commutator segment corresponding to a later machine. Contact arm 33 then drops to a stop 30 and releases contact-locking bar 25. The commutator 11 is driven by a motor and the brushes 45, 55, may be connected through a friction clutch so that they may be stopped by a pawl when a fault occurs.

Apparatus for intravenous administration of liquids comprises a liquid reservoir 15, in communication with a conduit 13 via a suitable flow control assembly 17, e.g. a signalcontrolled valve or clamp, and a temperature responsive transducer, e.g. a thermocouple or thermistor 21, the electrical output from which is amplified at 27 and fed to a variable threshold detector 29 adapted to produce an output only when the input from the amplifier 27 lies in a certain range. In use, a cannula 11 is placed into an artery and the transducer 21 is placed nearby on the skin. Preferably a second transducer 35 is placed on the at a distance from the first and the amplifier 27 adapted to amplify the difference of the outputs from both elements. If liquid from the reservoir starts to collect under the skin, the skin temperature falls closely to the temperature of the liquid used. Such a drop in temperature causes an output from the detector 29 to operate the control assembly 17 and/or an alarm 33 to prevent further liquid flow. Alternatively a generator of a reference signal may replace the second transducer 35, or an initial temperature recorded, using the first element 21, and used to pre-set the detector 29.

Downward movement of the handle is limited by the abutment of handle members 42 against tabs 31 in the partitions. The longitudinal partition is adhered to the box walls by glue panels 23, 25. The glue used is a pressure adhesive so that it is arranged to have co-operating panels of glue for the parts which are to be adhered together. The carton may be open-topped.
