Abstract: 263,785. Urbana Coke Corporation, (Assignees of Parr, S. W., and Laying, T. E.). Jan. 2 1926, [Convention date]. Retort furnaces; charging and discharging; cooling discharged materials.-In the coking of solid fuel such as coal, the fuel is preheated without exclusion of air in a container by waste flue gases before being passed through a rotary retort in which further heating takes place, the fuel then being coked in vertical retorts, the hot flue gases from which are passed in turn through a jacket surrounding the rotary retort and through the preheating device. The temperature of the rotary retort is controlled by a burner responsive to the temperature of the fuel leaving the retort. The fuel is fed into a preheating container 18 through which pipes 19, traversed by hot waste flue gases from a pipe 20, pass, and is supplied by a screw conveyer 10 rotating in timed relation to a rotary drum or retort, 25 to one end of the latter. This drum is enclosed in a heating chamber 26<1> traversed by hot gases entering by a pipe 16 and leaving by the pipe 20 and is so mounted that its angle of inclination may be varied by a jack 36. The temperature of the drum is maintained constant by a gas burner 30 controlled by a regulating device 32 and a thermo-couple 33 responsive to the temperature in a discharge hopper 11 so that the fuel is maintained at a temperature of 30‹ C. below that at which it becomes plastic. The fuel is discharged into a car 12 mounted on a track 40 supported on a transverse track 41 to permit of charging the vertical retort battery 13 below. The retorts 44 are enclosed in a chamber 45 heated by gas burners 47 at the bottom of up flues 51 leading to down flues 52 discharging the hot gases through passages 53 into contact with the retorts, the. walls 48 being thus heated to radiate heat uniformly. The hot gases pass out through a manifold 55 communicating with the pipe 16. The air for the burners is admitted through passages 72, 63 and preheated in flues 64, 65 leading to passages 67 below the burners, valves 68, 69 controlling the supply of air to the heating passages and to the passage 67 respectively. The coke is cooled in a reservoir 14 provided with passages 70 in which air is preheated before reaching the burners. A vent 74 connects the gas outlets 73 and leads to the main the gas and ammonia from steaming the coke.

Inventor: PEAT DEREK
IPC: G01P3/50
Filed: 1968-07-02
Abstract: 1,219,666. Knitting-machines. NATIONAL RESEARCH DEVELOPMENT CORP. 1 July, 1969 [2 July, 1968], No. 31609/68. Heading D1C. [Also in Division G4] An electrically non conductive member, e.g. yarn 29 (Fig. 1) is marked by applying a discrete region of electrostatic charge to it, the subsequent detection of the charge by detector 13 resulting in a further mark being applied to the member. As described for use in fully fashioned knitting machines each pulse from detector 13 is fed to a gate 25 enabled by the output of a photocell 37 when a screen 33 on the slur bar 31 of the machine obscures the light source 35 from the cell. The count in a counter 27 receiving the detector pulses via gate 25 then represents the average length of the stitches since the slur bar is of known fixed length. The counter may control a display 4i and a quality control governor 43 which detects any discrepancy between the detected and required stitch size and through solenoids 45, 47 controlling a ratchet and pawl mechanism adjusts automatically stitch size. If the measuring apparatus is used in a Jacquard machine, gating is effected by a microswitch triggered once per course of knitting. Yarn speed may be measured by gating the count for unit time.

Title: Improvements in and relating to change speed gearing for motor propelled vehicles
IPC: F16D49/10
Filed: 1932-02-29
Abstract: 402,793. Brake drums; change-speed gearing. WILSON, W. G., and WILSON, A. G., 23, Queen Anne's Gate, London. Feb. 29, 1932, No. 31745/33. Divided on 402,778. [Class 80 (ii).] Relates to means for arresting and holding stationary substantially cylindrical drums such as the reaction drums of change-speed epicyclic gearing of the Wilson type, as described, for instance, in Specifications 164,042 and 312,128, [both in Class 80 (ii), Gearing, Variable-speed &c.]. When such drums are machined inaccurately so as to have a slight taper, the brake grips at one end only of a drum resulting in " judder " and end thrust. To obviate this, the braked surface of a drum such as a, Figs. 3 and 4, is formed with a series of continuous annular grooves b and the brake lining is of such a kind as to become deformed so as to accommodate itself to the engaged drum surface. The grooves b are in planes normal to the drum axis. In Fig. 3 is shown a section of a two-part brake G described in Specification 220,021, [Class 103 (i), Brakes &c.]. The two brake linings c, dare pressed more deeply into the grooves b at the large end L of the drum than is the case at the small end S, and yet there is contact at points all along the drum. The grooves b may be distributed in groups with gaps a<1>, Fig. 5, between them. The grooves b are preferably cut V-shaped and to a depth of from À03 to À1 inch. Specifications 370,442 and 402,778 also are referred to.

Title: Method for tightly closing tubes made of ceramic-metal composite materials, for example sheaths for the fuel elements of nuclear reactors
Inventor: AGACE CARLO
IPC: G21C3/10
Filed: 1964-08-05
Abstract: 1,070,204. Welding by fusion; brazing; stamping. EUROPEAN ATOMIC ENERGY COMMUNITY (Euratom). Aug. 5 1964 [Aug. 6, 1963], No. 31767/64. Headings B3Q and B3R. [Also in Division G6] A method of closing the ends of tubular elements made of ceramic metal composite materials comprises the steps of closing the end of the tubular element with a plug having a projecting flange which co-operates with the element to form an annular cavity around the mouth of the element, securing the plug in the element, inserting in the cavity a ring of the same metal as the matrix of the composite material, said ring having a size to project from the cavity and heating the ring so that it melts and the metal diffuses into the element and the flange of the plug. A tube 13 made of sintered aluminium containing a high percentage of alumina and forming the sheath of a nuclear fuel element is internally threaded at 19 and has a counterbore 20. The plug 15 of the same material has external threads 18 and a flange 17, which is reduced in diameter at 21 to form, with the element an annular cavity which receives an aluminium ring 22. The thickness of the metal of the sheath and plug on each side of the ring is the same and is equal to the projection of the ring above the cavity. Preferably the thickness (i.e. the axial length) of the plug 15 is ten times the wall thickness of the tubular element, and twice the axial length of the ring 22. The plug is secured in the element by swaging and is then rotated at 2 r.p.m. and bombarded by an electron gun 23 which causes fusion of the ring to produce the joint shown in Fig. 7. Argon or helium shielded arc-welding using a tungsten electrode may be used in which case the ends of the tube and the plug flange are chamfered at 45 degrees to contain the molten metal of the ring. In a modification, the threads 18 and 19 are omitted and the plug is formed with a cannelure (27), Fig. 10 (not shown), into which the tubular element is electromagnetically swaged. In a second modification, Fig. 11 (not shown), the counterbore 20 is omitted from the element and the full radial depth of the cavity is formed by machining the plug. In a third modification, Fig. 12 (not shown), the method is applied to special sheathing tubes having a solid plug (30) through which thermocouples extend. The ring (32) has an angular crosssection and is received in a cavity comprising a counterbore (34) in the sheath and a V- groove formed by chamfered flange (31) on the plug and the chamfered end of the tube. In a further modification the plug is coated with silver and heated to obtain a mechanical connection by diffusion.

Filed: 1955-11-07
Abstract: 794,605. X-ray apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 7, 1955 [Nov. 6, 1954]. No. 31778/55. Class 98(1) [Also in Group XXXVII] A carriage 4 for X-ray apparatus is supported by rollers 5, 6 on a frame 1 and is driven by means of an electric motor 12 having an armature 12a and a field winding 12b, the armature being supplied through reversely-connected discharge valves 21, 22, and the field winding through bridge rectifier 20. When a control handle 27, which is.mounted on the carriage 4, is moved upwardly from its central spring-biased position in which the motor is de-energized, a contact 31 moves from conductive bar 34 and slides along resistor 32 whereby the voltage input to transformer 26 increases. This causes the grid potential of the valve 22 to increase so that the valve fires and the motor is energized for movement of the carriage in the appropriate direction, the speed of movement increasing and decreasing with the amount of pressure exerted upon the control handle..If the handle 27 is pressed downwardly the carriage moves in the opposite direction in a similar manner. Transformers 35, 36, act upon the grid circuits 23, 25, of the valves 21, 22, respectively so as to prevent the development of excessive motor current, due to the carriage meeting a stop member at the end of its travel, for example. The maximum torque of the motor may furthermore be controlled in dependence upon the inclination of the frame 1 which is adapted to turn about the journals 2. For this purpose, the secondary circuits of the current-limiting transformers 35, 36, comprise potentiometers which are adjusted by sliders coupled to the movable frame, Figs. 2, 3 (.not shown).
