Title: Improvements in or relating to Formation Fluid Samplers
IPC: E21B49/08
Filed: 1967-01-12
Abstract: 1,158,503. Wells &c. BYRON JACKSON Inc.. 12 Jan., 1967 [24. Jan., 1966], No. 1780/ 67. Heading E1F. Apparatus for sampling formation-fluid comprises a sample receiving chamber 43 having end apertures 39, 41 closable by linked plugs 48, 49. The apparatus is embodied in a pipe string, the part 21 being connected to a perforated pipe receiving the fluid from the formation and a valve being incorporated between the apparatus and the perforated pipe. The valve is closed and after the pressures in the string below the valve become steady the valve is opened, the fluid flowing through the chamber and parts 86 into an extension 73 of a rod 44 carrying the linked plugs. From the extension the fluid flows upwardly through passages 94, 101, 102 and the interior of the pipe 32 to the surface. The pipe 32 is rotated to cause a threaded member 30 to lift the rod and its extension to close ports 86 until a steady pressure is reached in the chamber. The string is then further rotated to lift the rod and its extension until the ports 86 are opened and the apertures 39, 41 are almost closed by the plugs. The rod and extension are then further rotated to close the apertures and block flow above the ports 86. A spring 60 is compressed by a cup 59 holds the linked plugs in the closed position and an annular projection 51 is lifted clear of the plug 49 so that fluid may flow through an annulus 47 to balance the pressures on both ends of the chamber. Mud may be pumped down through the apparatus and through the perforated pipe into the borehole, the pressure of the mud displacing a plug (not shown) at the foot of the passage 45 so that the mud can pass through passages 71 into the string below the apparatus shown. The parts 22, 23 forming the chamber and the linked plugs may be withdrawn from the string and fitted with handles, the lower handle serving to keep the linked plugs in position.

Title: Improvements in turbo-jet units
IPC: F02K3/12
Filed: 1956-01-19
Abstract: 793,986. Jet-propulsion gas-turbine plant. CAILLETTE, G. Jan. 19, 1956 [Jan. 25, 1955; Jan. 25, 1955], No. 1813/56. Class 110 (3). [Also in Group XXXIII] In a jet-propulsion engine comprising a gas turbine driving the compressor which supplies air to a combustion chamber which supplies the motive gases to the turbine, the angular momentum of the turbine and compressor rotors is counterbalanced by the equal and opposite angular momentum of a rotating mass which may comprise engine auxiliaries such as dynamo-electric machines, fuel pumps or auxiliary air compressors, one or more flywheels or another jet-propulsion engine. This obviates gyroscopic effects. Fig. 1 shows a jet-propulson engine in which the angular momentum of the compressor and turbine rotors 6, 7 is neutralized by that of a flywheel 18 and the rotor 11 of a dynamo-electric machine, driven through bevel gearing 13, 15, 14, 16 at the same speed as the rotors 6, 7, but in the opposite direction. If a propeller 21, rotating in the opposite direction to the rotors 6, 7, is provided, the angular momentum of the propeller and its reduction gearing 22 is taken into account. In another embodiment, the gyroscopic balancing is done by a flywheel comprising a rim connected to a hub by arms which are formed as turbine blades and acted upon by the turbine exhaust so that the flywheel rotates in a direction opposite to that of the turbine and compressor rotors. In a further embodiment, Fig. 3, the rotors 46, 52 and 46<SP>1</SP>, 52<SP>1</SP> of two jet-propulsion engines are connected by bevel gearing 53 so as to rotate in opposite directions to balance each other gyroscopically. If the engines are of different moments of inertia, the ratio of the gearing 53 differs correspondingly from unity. The air intakes 42, 42<SP>1</SP> of the two engines are fed from common intake passages 47, and the front engine has two discharge conduits (not shown) leading from the exhaust nozzle 43 and symmetrically arranged with respect to the axis of the engine with extensions which are bent so as to direct the exhaust gases in the rearward direction. A flap valve 59, controlled manually or automatically, is provided in each intake 42, 42<SP>1</SP> for closing the intake of an idling engine. Pins connecting the two parts 56, 57 of a coupling are sheared in the event of sudden stoppage of one engine.

A breathing-mask has a window secured in a slot in a bead around the window, clamping means engaging the bead on opposite sides of the slot and being spaced from the bead where it surrounds the edge of the window. A rubber facepiece 1 has a window opening 3 surrounded by an integral bead 4. A window 6 is fitted in a slot 5 in the bead 4, the sides of which are clamped together by a clamp 10 which encircles the bead 4. The clamp 10 comprises rigid upper and lower interchangeable halves each having an outer flange 11, which engages a shoulder 7 on the bead 4, and an inner flange 12 which engages a groove 8 formed between the bead 4 and the facepiece 1. The halves of the clamp 10 are drawn together by screws 16 engaging lugs 15 at their ends and thus stretch the bead slot 5 over the edge of the window 6 and press the sides of the bead slot 5 against the window 6. When in position a space 13 is left between clamp 10 and the part of the bead 4 adjacent the extreme edge of the window 6. The facepiece has a flexible sealing lip 2 near its edge and grooves 19 adjacent the ends of the window 6 to increase the flexibility of the facepiece. An air supply is connected to a coupling 23, air flowing, on inhalation, into a housing 21 and thence by way of an inhalation valve 26 into a space between the facepiece and a deflector 31. Most of the edges of the deflector 31, which is secured around a speaking diaphragm 32 by a ring 33, contact the facepiece 1 to define a duct on each side of the facepiece. The ducts open adjacent the ends of the window 6 so that air sweeps across the window 6 before being inhaled. A tube 24 extending through the deflector 31 and the housing 21 conveys exhaled air to an exhalation valve 27. In an alternative construction (not shown) the tube 24 is omitted and inhalation valves are provided in the air inlet housing and in the ducts formed by the deflector. Exhalation valves are provided in the base of the deflector and in the housing. The inner flange of the clamp 10 may be replaced by a band pressed against the groove between the bead and the facepiece by the clamp. Specification 837,355 is referred to.

Abstract: 432,199. Television. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, Liverpool, and SIMPSON, L. M., Lyndene, Kensington Avenue, Thorner, near Leeds. Jan. 18, 1934, No. 1855. [Class 40 (iii)] A record 28 of a scene is transmitted at a speed less than that at which it was produced so that the signals occupy a frequency band similar to that normally used in broadcasting. The scene is scanned by a cathode-ray tube of the " Iconoscope " type, which controls a Kerr cell to produce the photographic record 28, Figs. 1 and 2 (not shown). The scanning is controlled by the drive for the photographic film so that the same amount of scanning always occupies the same length of film. The record is moved between a light source and a photo-electric cell 31 connected to a broadcast transmitter. The synchronous motor 29 drives the record at such a speed that the signal frequency does not exceed 9,000 cycles. At the receiver the photographic record is run off at high speed to control a beam of light which is synthesized into the scene by a rotating mirror drum, Fig. 5 (not shown). The film drive is connected to the mirror drum through a differential gear to facilitate framing, Fig. 6 (not shown). The record may be made by a scriber on an opaque film and may be accompanied by sound. A kinematograph film may be used, and the signals recorded magnetically, Fig. 7 (not shown).

Title: Improvements in and relating to photo-electric relays
IPC: H01J40/14
Filed: 1933-01-21
Abstract: 414,102. Valve circuits. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Cookrell, W. D. ; 1, Rugby Road, Schenectady, New York, U.S.A.) Jan. 21, 1933, No. 2031. Convention date, Jan. 21, 1932. [Class 40 (v).] A relay 32 controlled by a photoelectric cell 12 operates upon an increase or upon a decrease of illumination, according to the setting of switches 8, 13. The relay includes a valve 30 of the vapour type having a plate-voltage-interrupter 37 and a shunt resistance 38 for ensuring that the interrupter shall be effective even if its open-circuit resistance is not infiriite. The gas-filled photoelectric cell 12 controls a screen-grid valve 18 which controls the vapour valve 33, and these parts are tapped off a potential-divider 3, 4, 5 (or 9), 6, 7 which is connected between the positive and negative mains 1, 2. In the condition shown and in the dark the control grid 18g is negative, but when the cell 12 is illuminated it connects the grid to the positive point 10 and thus operates the relay. When the switches 8, 13, are thrown, however, the direction of current through the valve and cell is reversed and the relay then operates upon a decrease of illumination. The resistances 5, 6, 7, 9, 15 are so arranged as to ensure that in both cases the cell 12 shall receive the correct voltage, account being taken of the grid current which flows in resistance 15 when the switches are thrown. The voltage-drop in the plate-circuit resistance 20 is applied to the vapour valve 33, the current flow in which has to be extinguished periodically by the plate-circuit interrupter 37. In case the interruption should be imperfect, the valve is shunted by a resistance 38 which ensures that the drop in plate voltage shall be adequate to cause extinction. Valve 18 is protected against the plate voltage becoming excessive by the fact that when this valve is inactive, and valve 30 is consequently active, a voltage-drop is set up in resistance 20 by grid current flowing through resistance 35. A condenser 39 is provided for the purpose of effecting an initial kick of current for operating the output relay 32, the steady current through valve 33 being only sufficient to hold the relay when once it has been operated.

Filed: 1967-01-16
Abstract: 1,125,030. Rotary pumps. ITT. INDUSTRIES Inc. Jan. 16, 1967 [Jan. 14, 1966], No.2121/67. Heading F1F. In a rotary pump of the flexible-vane type comprising a housing 32, Fig. 1, including a pumping chamber 34 in which rotates a rotor 38 formed with a plurality of flexible vanes 40, the chamber profile is formed by two surfaces 42, 44 having different radii inter-connected by cam surfaces 46, 48 spanning inlet and outlet ports 50, 52 respectively to smoothly blend with the surfaces 42, 44 and at least one of said ports is fitted with a removable bridge-piece which supports the vane tips as the vanes slide across said one port to prevent the momentary extension of the vanes into the ports and so lengthen the life of the vanes. In its simplest form, a bridge-piece 90, is associated with the outlet port 52 and comprises a flat blade element 92 shaped at its inner end 100 to correspond to the surface 48 and an outwardly flared portion 96 which seats in grooves 98 in the coned end 56 of the port 52 so that the element 92 is maintained parallel to the direction of movement of the vane tips. The pump is intended for use in pumping liquids, e.g. milk, in which strict cleanliness is essential and for this purpose the edges 94 of the element 92 are rounded to make line contact with the port 52 and the bottoms of the grooves 98 so that flowing liquid cleanses the pump outlet. A coupling nut 72 permits the easy removal of the element 92 for cleaning. Instead of having a shaped end 100, the element may have a plane face normal to the bridge axis positioned slightly within the inner end of the port 52. This will give sufficient support to the vane tips when sweeping over the port 52. Other forms of bridge-pieces are described, e.g. two parallel spaced apart flat blade elements connected at their outer ends to a ring having projections on its outer periphery which engage grooves in the port base to correctly locate the bridge-piece. The bridge-piece may also be in the form of a wire bent to various shapes and sprung into a groove at the mouth of the port 52. The bridge-piece is made, e.g. of stainless steel or plastics material unaffected by the liquid being pumped.
