Title: Automatic Earth Driller.
IPC: E21B47/09
Filed: 1967-09-19
Abstract: 1,192,228. Drilling earth. SMITH INDUSTRIES INTERNATIONAL Inc. 19 Sept., 1967 [19 Sept., 1966], No. 42639/67. Heading E1F. Earth drilling apparatus comprises a bit on the lower portion of a drill string and positioning means at the upper portion of the string for raising and lowering it, down-hole signalling means responsive to the position of the bit relative to the upper portion, and surface means responsive to the signalling means for controlling the positioning means, Fig. 1 shows part of a telescopic joint between the upper portion secured to outer pipe 12 and the lower portion secured to inner pipe 11. The string is suspended from a a rotary drive motor on a carriage movable up and down a portable mast, Fig. 5 (not shown) by a second motor. Working and cooling fluid (such as air) for the (percussive) bit passes down the string and as the bit descends, the joint extends, and a plug 97 on string 92 nears throat 99, to throttle the air flow. The air compressor feeding the string automatically raises its output pressure in response and this pressure rise is used to initiate lowering of the carriage and string by the second motor, by various arrangements of pressure operated valves. The string may be lowered for a predetermined time, by time delay in the closing of a valve, or for a predetermined distance by means holding a valve open, once opened, until the carriage has descended by a fixed amount. In an alternative, extension of the joint near its limit causes leakage of working fluid, the resulting pressure drop causing descent of the string until the joint contracts sufficiently to cause a plug and throat to throttle the flow, the resulting pressure rise terminating descent of the string. In a further embodiment extension of the joint permits working fluid to flow past an edge which sets up vibrations detected by a surface microphone. Extension of the joint may alternatively be signalled by electrical or magnetic devices.

Title: Improvements relating to filters
Inventor: BLAKEMORE JAMES DAVIES
IPC: B01D29/00
Filed: 1968-09-09
Abstract: 1278241 Moving band filter BLAKELL INDUSTRIAL PLANT Ltd 9 Sept 1969 [9 Sept 1968] 42744/68 Heading BID A moving band filter comprises a housing divided by a horizontal plate 19, having a central aperture, bridged by a grid 21, over which a filter element mounted between two chains 23 is extended, and end apertures 19a through which the chains enter the chamber above plate 19, hoods 24 being lowered by pneumatic rams 47 to seal apertures 19a before liquid is pumped into the chamber. Chains 23 are entrained over sprockets 31 and are connected by flat links (27). Filter elements are mounted between adjacent pairs of links (27), which are located under the inner edges of hoods 24 when the hoods are lowered. The hoods and plate 19 round apertures 19a have resilient seals 25, (26). A filter cloth may be extended from a supply roll 43 across the upper run of the chains, the 'filter elements' then having a supporting function only. Connected to hoods 24 is a rectangular clamping frame 38 which clamps the element or cloth round the periphery of grid 21 when the hoods are lowered. The frame is connected to the top of the chamber by pervious and flexible curtain 39. When liquid is pumped in through valve 28, some filters down through the cloth or element and some outwards through curtain 39, thereafter exerting additional sealing pressure on hoods 24. When the cloth or element clogs, the rise in pressure causes valve 28 to close and valve 46 opens to admit compressed air to force remaining liquid through the cloth. Escape of this air causes the hoods to be raised, valve 46 to be closed and the drive motor (37) to advance a new element and possibly a new section of cloth, carrying the old element, cloth and solids out of the chamber.

Title: Improvements in or relating to remote position control apparatus
Inventor: FITZGERALD GERALD
IPC: G01S7/40
Filed: 1959-12-28
Abstract: 890,819. Radar. DECCA RECORD CO. Ltd. Dec. 20, 1960 [Dec. 28, 1959], No. 44031/59. Class 40(7). [Also in Group XL(b)] In a remote position control apparatus, a rotatable follower element, e.g. the deflection coils or the resolver of a P.P.I. radar apparatus, is driven by a motor synchronously with a continuously rotating member, e.g. a radar aerial, and switches are associated with the member and the follower which each produce a pulse during each revolution, the pulses feeding a bi-stable circuit which controls the engagement of a clutch in the drive from the motor to the follower, thereby to make the angular position of the follower correspond exactly to the position of the rotating member. As applied to a radar apparatus having rotating deflection coils, the coil holder 21 is required to be kept in synchronism with the aerial 12 driven by a motor 16. A generator 19 driven from the aerial shafting feeds a synchronous motor 20 which, via a clutch, drives the coil holder 21. A switch 22, which may be the heading or azimuth bearing marker switch, is closed once in each revolution of the aerial to provide a voltage 'reset' pulse at the grid of valve 25 part of a bi-stable circuit circuit. A second switch 27 mounted on the coil holder 21 may be adjustable there-about and is also closed once per revolution to give at the grid of valve 25 a 'set' pulse which has a shorter duration than that of the 'reset' pulse, this being ensured by the differentiating network 29, 70. In operation, if a 'set' pulse occurs valve 25 conducts and the clutch is disengaged so that the coil holder stops rotating. The clutch, Fig. 3 (not shown) is disengaged by the passage of anode current in the coil 55. Upon the closure of switch 22, the 'reset' pulse causes the clutch to be reengaged. The 'set' pulse being shorter than the 'reset' pulse the clutch is not disengaged if the two pulses are in substantial coincidence.

Filed: 1967-09-29
Abstract: 1,164,390. Detecting gases electrically. GENERAL ELECTRIC CO. Sept.29, 1967 [Nov.25, 1966; June 21, 1967], No.44537/67. Heading G1N. [Also in Division H1] A combustible gas detector comprises a thin indium sesquioxide film heated by a heater adjacent the film to a temperature above its transition temperature, thereby converting it to an intrinsic semi-conductor, and connected as a resistor to a power supply; an ammeter being provided by which its resistance is determined. A combustible gas is detected by one of two effects. If the gas contains atomic hydrogen, e.g. hydrocarbon gases such as methane, the heater catalytically cracks the gas releasing the hydrogen which is then reversibly absorbed by the indium sesquioxide film giving up an electron to the film, thereby increasing its conductivity in proportion to the amount of the gas present. For all other combustible gases the heater raises the gas temperature above its combustion point, the heat of combustion of the gas increasing the temperature of the N.T.C. film to thereby decrease its resistance. The indium sesquioxide film 23, Fig.3, is deposited, e.g. by evaporation techniques, on the central part of a support 22 of dielectric material, e.g. quartz, the ends of the support being coated at 24, 25 with a noble metal, e.g. platinum, and platinum wire 26 wound round these coatings to provide electrical connections to the indium sesquioxide film. The heater coil 31, e.g. of platinum, is wound round but spaced from the indium sesquioxide film, the gas to be analyzed being directed through this gap.

Abstract: 1402695 Unloading discs from a cartridge INTERNATIONAL BUSINESS MACHINES CORP I Oct 1973 [13 Nov 1972] 45758/73 Heading G5R When unloading laminar members 2 from a cartridge 1, e.g. in a dictation apparatus using magnetic discs, insertion of the cartridge into an unloading station to a first extent releases a disabling engagement between an unloading member 28 and a lever 29 and insertion of the cartridge to a second extent, further than the first extent, releases a disabling engagement between member 28 and a lever 33, member 2 being unloaded from cartridge 1 by engagement between members 2 and unloading member 28 during withdrawal of cartridge 1 from the second extent of insertion. Levers 29, 33 have edges 4, 22 respectively which are engageable with a finger 14 to disable member 28. When edges 4, 22 have been released from finger 14 by the cartridge first engaging guide 32 of lever 29 and then edge 18 of lever 33, a spring 12 pivots lever 28 so that a latch 19 thereof rides on a surface 9 of lever 33 during further movement thereof by the cartridge and the latch 19 rides on edge 18 as the spring 12 brings a finger 3 of lever 28 into central openings 27 of members 2 so that the latter are pulled out of cartridge 1 during withdrawal thereof, engagement of latch 19 with edge 18 preventing a spring acting through lever 33 to lift the finger 3. When the cartridge 1 has been withdrawn to said first extent of insertion, the lever 29 is released and is moved by a spring 10 to lift finger 3 from apertures 27 and disengage latch 19 from edge 18 whereby the initial position is resumed with edges 4, 22 engaging finger 14 to disable unloading lever 28. The spring 10 may cause the guide surface 32 of lever 29 to push the unloaded laminar members 2 towards an aperture 23 through which the members 2 are moved (by means not detailed) to other stations. The apparatus may be used in dictation apparatus similar to that of Specification 1,364,906.
