Title: Convertible well packer and bridge plug
IPC: E21B33/12
Filed: 1963-04-02
Abstract: 1,003,233. Wells, &c. BAKER OIL TOOLS Inc. April 2, 1963 [April 13, 1962], No. 12991/63. Heading E1F. A well packer A having a through passage 10 and adapted to be set in a casing B is converted into a bridge plug by means of a plug D which may be fixed within the passage by latches 39. The packer and plug are run into the well on setting apparatus comprising members 69, 70. The packer is set by moving the member 69 upwardly and member 70 downwardly, the slips 14, 21 and a structure 18 engaging the casing. After the packer has been set a release stud 67 is fractured and the setting apparatus withdrawn from the casing. As shown in Figs. 1, 1a the plug is held in the passage by the latch fingers 39 which engage a thread 41 on the body 11 of the packer, the fingers being held into engagement with the threads by a retainer 45 which also serves to close a bore 57 in the plug so that the packer and plug act as a bridge plug to close the casing. The plug is removed from the packer so that the packer may serve as a production packer. A tubing string E forces the retainer to the position shown in Fig. 5 after shearing pins 50. In the position shown in Fig. 5 the latch fingers are free to move inwardly and the bore 57 connects the upper and lower sides of the plug to equalize pressure. Further downward movement of the string ejects the plug from the packer. In a modification internal pads are attached by shear pins to the parts 51 of the latch fingers, the arrangement permitting the plug to be lowered by a running string into a packer which has been set in the casing.

Title: Improvements in magnetic core and method of making the same
IPC: H01F41/02
Filed: 1958-04-24
Abstract: 832,599. Making magnetic cores. GENERAL ELECTRIC CO. April 24, 1958 [May 1, 1957], No. 13036/58. Class 83 (2). [Also in Group XXXV] A method of making a magnetic core comprises forming bumps in sheet or strip magnetic material and subsequently annealing the material. The strip of silicon steel magnetic material 7 is insulated by passing it through a liquid composition bath 19, is then rolled between rollers 11 and 12 having intermeshing elements which form bumps 9 spaced from the edge of the strip and is then wound on a rotating mandrel 8 to form a core which is subsequently compressed to collapse the bumps between four side acting dies 16 and the mandrel. The core is annealed at 800‹ C. in a furnace after being externally banded to prevent the turns from enlarging to remove strains and permanently set the turns and is then unwound cut into a plurality of strips rewound and linked to a winding assembly in known manner. The bumps 9 may alternatively be collapsed by the annealing or by both the compression and the annealing processes. The method may also be used with plate cores and strip wound cores of the hinged, C, and circular type. Specification 545,229 is referred to.

Title: Improvements in and relating to electron discharge devices
IPC: H01J31/04
Filed: 1933-05-06
Abstract: 422,413. Discharge apparatus. SCHWERIN, P., 6, Farwell Road, Sidcup, Kent. May 6, 1933, No. 13272. [Classes 39 (i) and 40 (v)] Two thermionic systems are so arranged that their interelectrode gaps do not overlap, and one of the systems creates a conductive region influencing the electrodes or the interelectrode gap of the other system, means being provided for modifying or suppressing the conductive region to start, stop or modulate the second discharge. In one form, Fig. 1, the controlling system consists of a cathode b and a tubular anode c, whilst the controlled system consists of a cathode d and a flat anode e. The envelope may be evacuated or gas-filled. A pair of plates f serves to direct the beam for the system b, c, or a magnetic control may be used. In other methods, the potential of the anode c or the temperature of the cathode b may be modified, or a control grid inserted. In a modification, an apertured diaphragm gives the electron beam a flattened cross-section and the electrodes of the second system are inclined to one another so that deflection of the beam in a direction normal to its plane causes it to traverse a varying interelectrode gap in the second system. In another modification, either or both of the electrodes d, e is given a shape which produces a desired effect upon the beam as shown for example in Fig. 4. In another modification a beam of flattened cross-section is given a rotary or oscillatory movement by electrostatic or electromagnetic means. More than one controlled system may be provided in conjunction with a single controlling system. Fig. 7 shows a circuit which may be used for generating oscillations. The circuit to the control electrode p has a coil p<2> coupled to a coil p<4> in the circuit of the system d, e. Modulation may be effected by varying the anode potential or the potential between the two systems. Voltages to be amplified are applied to deflecting plates, the amplified voltage appearing across a coil connected in series in the anode circuit of the system d, e. Fig. 10 shows a modified construction of tube in which the first system consists of a cathode r, a control grid s and an anode t through which current may be passed. The second system comprises four anodes u and cathodes v. Screens w are provided. A control grid may be inserted between the electrodes of the second system.

Patent GB-135055-A (GB)
IPC: B62J1/20
Abstract: 135,055. Mortimer, G. E. Jan. 31, 1919. Saddles.-In a spring. roller waterproof cover for cycle saddles, the roller is removably arranged within a casing A secured to a folding frame H clipped to the upper rear fork of the machine. When the cover is required, the frame is unfolded so that the casing occupies a position above and behind the saddle, as shown in full lines in Fig. 4; the cover P is then drawn out and a loop at the front engaged with a pin secured to the saddle peak. When not required, the cover is released from the saddle, and a wing- nut at I is then slackened so that the frame can be folded till the casing rests upon the mud-guard. The casing is fitted with a hinged lid. At one end the casing and frame are furnished with vertical slots to receive and prevent the rotation of a square pin secured to the end of the spindle within the roiler, and at the opposite end the casing and frame are perforated to receive a round projection upon the roller, the roller being solid at this end. The control spring is fixed at its inner end to the non-rotatable spindle and at its outer end to a sleeve secured within the end of the roller. After the lid has been opened, the square spindle end can be raised in its slots and the roller moved to an angular position so that the round projection can be disengaged and the roller removed from the casing. When the apparatus is folded down, the slot in the casing end allows any water carried into the casing to drain away.

Title: Synchronous thermal imaging system
IPC: H04N3/09
Filed: 1974-03-27
Abstract: 1444518 Infra-red scanning system HUGHES AIRCRAFT CO 27 March 1974 13603/74 Heading H4F An infra-red scanning and display system for use in an aircraft such as a helicopter for obtaining a thermal image of the terrain comprises a vertical array of detectors across which an image of the terrain is swept (i.e. azimuthal scan) by a mirror, the resulting simultaneous video signals from the linear detector array being passed to a time division multiplexer type processing arrangement operable in real time to sample the video signals and to render the samples sequential so that they correspond to a vertical image line scan, and the resulting vertical raster scan video signal being displayed, e.g. on a CRT, under the control of synchronizing pulses generated in the processing arrangement. The time division multiplexing is effected in two stages, for example in the embodiment described an N detector linear array is divided into four groups each including every fourth detector, i.e. N/4 detectors, the sampled outputs from the detectors of each group being first rendered sequential and then appropriately time division multiplexed with each other. An interlace mirror is including in the optical scanning system so that successive field scans are interlaced, i.e. an interlaced display of vertical lines is produced. An AGC circuit is associated with each detector and is responsive to a modulated reference signal derived thereby in response to a modulated automatic responsivity control light source. Any effect of a cold narcissus image formed in response to the detector array (which is maintained at a low temperature) by reflection from optics in the system is cancelled by providing a hot infrared narcissus vertical-image line source, a proportion of the output of which is modulated (by a modulating slit and beam splitter arrangement) to comprise the AGC control source. Adjustably positioned horizontal and vertical sight-lines (boresights) may be added to the processed video signal and displayed, the optical imaging telescope-type system including an adjustable vertical boresight mirror and the horizontal boresight being generated electrically in response to the horizontal sync pulse. In addition the optical system includes adjustable optical elements for narrow and wide field of views, and an adjustable pointing mirror.
