Title: Improvements in or relating to the manufacture of combustible gas
Inventor: HARTLEY WILFRED
IPC: C01B3/46
Filed: 1954-01-20
Abstract: 756,386. Oil-gas. HUMPHREYS & GLASGOW, Ltd. Dec. 14, 1954 [Jan. 20, 1954], No. 1758/54. Class 55(2). In a cyclic process for the manufacture of combustible gas from liquid or gaseous bydrocarbons in which plant-heating phases are alternated with gas-making phases and carbonaceous deposits on a contact bed are burnt in the plant heating phases, the gaseous flow is always through a heat-storage mass, a gas. making contact bed and another heat-storage mass consecutively, the sequence and direction of gaseous flow through the two heat-storage masses being periodically reversed while the gaseous flow through the gas-making contact bed is unchanged in direction throughout all the phases of the cycle. The gas-making contact bed may consist of refractory or catalytic material or it may be arranged in two sections in separate vessels one part being of refractory the other of catalytic material. In the arrangement shown in Fig. 1 there is a first regenerator 15, a gas-making zone 10 containing a bed of catalytic material 11 and a second regenerator 16. The regenerators 15 and 16 have combustion spaces 28 and 29 below their refractory masses and connections 13 and 17 and 14 and 18 leading therefrom to the top and bottom of the gas-making zone. Other connections 24 and 26 and 25 and 27 supply air and steam to the regenerators, waste gases leave by lines 19 and 20 and make gases by lines 21 and 22. Fuel and air are supplied to combustion spaces 28 and 29 by lines 30 and 32 and 31 and 33 respectively to provide for additional heating of the apparatus if this is necessary. In operation, when the plant is at operating temperature, during a gas-making phase, steam is passed through regenerator 15 by line 26 and into the gas-making zone 10 by line 13, oil is sprayed onto the contact bed 11 from a spray 12. Make-gases leave by line 18 and pass upwardly through regenerator 16 to the outlet 22. In a heating-phase air passes through regenerator 16 and into the gas-making zone by line 14 to burn off carbon deposited on the contact bed, waste-gases are withdrawn by line 17 and pass upwardly through regenerator 15 to outlet 19. This sequence may be repeated in subsequent cycles or the flow of steam and air may be reversed in alternate cycles or during a cycle. In a modified apparatus a combustion chamber separate from the regenerators may be provided for any additional heating required.

Title: Improvements in or relating to riveting tools
IPC: B21J15/04
Filed: 1946-01-19
Abstract: 606,825. Blind riveting. BRITISH UNITED SHOE MACHINERY CO., Ltd., and HENSHAW, J. N. Jan. 19, 1946, No. 1875. [Class 43] A tool for blind riveting comprises means for engaging the rivet to restrain its movement relative to the work, means for applying a pull to a deforming member to set the rivet, and a mechanical locking device actuated automatically when the magnitude of the pull reaches a desired degree, so that any further substantial increase in the pull is prevented. The tool is very similar to that described in Specification 348,818, but in the present case the levers 37 of the lazy tongs pivot on pins 39 mounted in a yoke 47 which is pivotally mounted on, and is embraced by, a U- shaped member 49 having in its base a threaded hole into which the casing 1 is screwed. The yoke 47 pivots on aligned pins 51 threaded into opposite sides of the yoke and received in holes in the walls of the member 49, the axes of the pins being slightly offset from the common axis of the casing 1 and sleeve 5. whereas the axes of the pins 39 are equally spaced from this common axis. The upper end of the sleeve 5 projects beyond the casing 1; it goes through, and can slide axially in, a hole in the base of the yoke 47, but very slight tipping of the yoke locks the sleeve against further movement. Normally the base of the yoke 47 is held at right angles to the axis of the sleeve 5 by a spring 53, which at one end engages an adjustment screw 55 threaded in a bracket 57 secured to the yoke 47, and at the other end engages a bifurcated lever 59 pivoted on a pin 61 mounted in the member 49 and carrying between its bifurcations a roll 63 mounted on a pin 65. The roll 63 engages an incline 67 on the yoke 47, which it tends to turn clockwise (viewing Fig. 2), but this movement is limited by a stop screw 69 threaded into the member 49. The rivet and mandrel used may be as described in Specifications 504,928 and 602,652. In the initial stages of a rivet-setting pull, the base of the yoke 47 remains at right angles to the axis of the sleeve 5, which can therefore move freely through the hole in the yoke. As the magnitude of the pull increases, the fact that the left hand pin 39 is further from the axis of the pins 51 than the right hand pin 39 gives rise to a turning moment about the pins 51, tending to move the yoke against the action of the spring 53. This turning movement does not cause tipping of the yoke 47 until it overcomes the force of the spring 53, which occurs when the magnitude of the pull reaches the desired degree determined by adjustment of the screw 55, and the yoke then tips slightly in a counter-clockwise direction causing the sides of the hole in the yoke 47 to lock the sleeve 5 against further axial movement, thus limiting the magnitude of the pull to that already applied and terminating the setting operation. Specifications 286,471, [Class 43]. and 558,156 also are referred to.

Abstract: 1377423 Press for packaging tobacco F B FISHBURNE 17 Jan 1972 [27 July 1971] 2213/72 Addition to 1326246 Heading B8C A press for packing fragmentary compressible material such as tobacco into containers comprises a distributer for acting on the material as it falls through a charger 1 from a feed conveyer 47 into a container to ensure an even distribution of material within the container prior to pressing by a vertically movable ram 4. For packing in circular containers (3, Fig. 1) the distributer comprises an arcuate plate 35 which can be pivoted inwardly by a fluidic piston device 37 from a rest position adjacent the cylinder wall to an operative deflecting position. The plate 35 is mounted on posts 29 supported on a ring 19 driven over flanged rollers 15 by a pulley belt 23 so that during operation the plate 35 travels back and forth along an arcuate path between a pair of limit switches 54, (53, Fig. 3) The limit switch circuitry includes manually adjustable time relay delays (55, 56, Fig. 5) for adjusting the dwell periods at each limit of travel. After a sufficient quantity of material has entered the container, the deflector returns to rest to allow the ram 4 to pass. The ring 19 may be provided with a finger (122, Fig. 7) for tripping a two position selector switch (126) connected to manually adjustable time delay relays (117-120) so that the dwell periods and length of travel of the plate 35 may be varied. Overtravel limit stops may be provided for the plate 35. For packing in rectangular containers the distributer comprises a pair of opposed pivotable plates 204, 205 interconnected by a fluidic piston device 214 having an adjustable piston length. For operation, pressure fluid is supplied to the device 214 via a pipe 229 whilst the piston is held stationary, by a fluidic piston device 221 thus causing the plate 204 to pivot inwardly from its rest position to its deflecting position. Pressure fluid is then supplied alternately through pipes 231, 232 to the device 221 whilst pressure fluid is supplied in the device 214 so that the plates 204, 205 are caused to pivot in and out in turn. Adjustable time delay relays 244, 248 enable the dwell periods and the time of pivoting to be varied. The charger 1 is provided wth a lower end portion (7, Fig. 1) of translucent fibre reinforced polymeric material. The circuitry for all embodiments is fully described (Figs. 5-7), Fig. 8.

Title: Transmission of Well Logging Signals.
Inventor: BARGAINER JAMES DANIEL
IPC: E21B47/12
Filed: 1967-01-16
Abstract: 1,151,804. Well logging. MOBIL OIL CORP. Jan.16, 1967, No.2315/67. Heading G1A. In an arrangement for investigating radiation in a well-logging system measured parameter values are transmitted to a remote point by discrete signals e.g. digitally, or by binary code. A sonde may include a neutron source 34 Fig.2 of plutonium beryllium or pulsed neutrons and parameters of secondary radiation may be measured by for example a scintillation crystal and photomultiplier 37-38, the resulting pulse heights or pulse durations being encoded by gating the output of an oscillator 84 to a binary scaler, the output from which is applied to one or more transmission lines 153-156 in sequence in response to an initiating pulse from a multi-vibrator 104 and under the control of a clock source 100. Arrangements are included to block the input path whilst the circuit is so acting, and the binary scaler is reset by a pulse from a multi-vibrator 92. At the surface, amplifying and separating circuits 55, connected one to each cable, insert the coded value in a register or analyzer wherein pulses of different radiation energy levels may be stored on for example magnetic cores, and counted, and may be readout for the production of a spectrum and/or may be recorded via a digital-to-analogue converter and a pulse-height analyzer which selects analogue pulses exceeding a selected threshold and width. The invention may be applied to measuring decay characteristics of the formations or elements therein, i.e. the decay of thermal neutrons or radioactive isotopes by the emission of gamma rays, the slope of a thermal neutron decay curve indicating the thermal neutron capture crosssection of formation elements. The formation is irradiated by pulses of fast neutrons for this last test, and detection may be made at predetermined time intervals after each pulse. Time intervals also may be transmitted in binary form. A Deuterium-tritium source of fast neutrons is exemplified, and it is pulsed by a blocking oscillator and a phantastron, the arrangement may be used to determine the presence of sodium and thus salt water, and a sodium iodide scintillating crystal detector may be used in conjunction with a photomultiplier. The uphole analyzer may respond only to radiation detected in a predetermined energy range, which may be adjustable.

The apparatus further includes a supporting structure, a pair of platens, one fixed 17, one movable 22, which receive and grip the material to be spliced therebetween, a supporting member 31 for the platen 22, an attaching element 30, means 34 36 for mounting the element 30 on the member 31 for bodily movement relative to the member 31, means 29, 32 pivotally securing the platen 22 to the element 30, and means 42, 44, mounting the supporting member 31 on the supporting structure, whereby the platen 22 is moved relative to the platen 17. The actuator is moved by means of a fluid-operated cylinder 55, whereas a similarly operated cylinder 45 moves the platen 22 by means of a rod 48 and the supporting member 31. The splicing is controlled by a switch 76 having an arm carrying a roller 77 which is engaged by the member 31 when the latter is lowered to the operating position. A limit switch 84 is motivated by the actuator 57 when the latter moves downwardly at the end of a splicing and resets the control for a further splicing. In operation, the tube is placed on the lower grippers 8, 9, with confining rubber pads 72 and the cylinder 45 operated, whereby the rod 48 moves the member 31 on its pivot 44 and so closes the platens on to the tube. The cylinder 55 now operates and the actuator 57 is raised whereby the clamping arms 51, 52 are raised through table apertures 66. Such movement is limited when pins 54 bear against the lower edges of slots 53 but continued operation of the actuator now draws the clamping arms together and so squeezes the gripper bars together.
