Abstract: 365,554. Gas producers. PALLEMAERTS, F. A. F., 100, Avenue de la Toison d'Or, and UNION CHIMIQUE BELGE, 61, Avenue Louise, both in Brussels. Oct. 20, 1930, No. 31464. [Class 55 (i).] Fuel is gasefied in a continuous process by the admission to a producer of a gaseous mixture rich in oxygen and of steam, the percentage of the oxygen being automatically kept constant, and the percentage of the steam variable so as to reduce the temperature of the fuel bed below the ash melting-point. 90 per cent oxygen from a source 1, and 35-70 per cent oxygen from a source 4, mix in a double-acting valve 9, with or without air drawn in at 11, and the mixture is admitted to a producer 13 through a pipe 12. The producer may be water-jacketed so that the gaseous mixture may be saturated with water vapour before admission into the producer at 15 ; a separate admission of water vapour may also be made. The volume of oxygen is kept constant by an automatic diaphragm analyser arranged at. 20. The diaphragm of the latter is calibrated and responds to the variation of gas density in the valve 9, this variation controlling the opening of a flap valve 21 in the pure oxygen conduit.

Abstract: 1,061,711. Magnetrons. S-F-D LABORATORIES Inc. Aug. 9, 1963 [Aug. 10, 1962 (2); Aug. 27, 1962; Sept. 6, 1962; Sept. 13, 1962], No. 31643/63. HeadingHlD. In an inverted magnetron with the cathode 9 surrounding an array of cavity resonators formed by anodes vanes 6 and with alternate resonators communicating through slots 7 with a central cavity resonator, waveguide or coaxial line supporting a circular electric mode, coupling to the output waveguide 2 is via an annular slot formed between the circular plate 13 and the surrounding anode wall in order to suppress more heavily loaded non- circular modes..The plate 13 may be replaced by a star- or snowflakeshaped plate, Fig. 6 (not shown), which is secured to the anode wall at its tips. Desirable coupling is enhanced by notches in the sides of the plate. The plate 13 is supported ,by a rod 14 which is axially slidable within a sleeve ,22 and sapphire ring bearings 23 so that the plate 13 serves also as a tuner. An annular slot mode absorber 24 consisting of a carbon-impregnated alumina ceramic is carried by the free end of the anode wall and, in order to eliminate unwanted radiation from the anode slots, annular conductive bands are provided to cover the ends of the slots, preferably on the vane side of the anode wall. These bands are secured to the anode wall through highly resistive electrical contacts. The anode wall is fixed to the tube envelope 1 only at the end remote from the slot mode absorber 24 so as to permit unrestrained axial movement at the free end. In another embodiment, Fig. 10 (not shown), the anode structure is carried from an insulator (52) by a shaft (55) supported by a transverse header (54). The cathode 9 is supported by spring fingers from three equally spaced stand-off insulators 72.

Title: Improvements in or relating to bonded articles such as abrasive wheels, and methods of and means for making them
IPC: B24D18/00
Filed: 1931-12-28
Abstract: 394,669. Moulding abrasive and refractory articles. CARBORUNDUM CO., Ltd., Trafford Park Road, Manchester. -(Carborundum Co. ; Niagara Falls, New York, U.S.A.) Dec. 28, 1931, No. 31691/32. Divided on 394,667. [Class 87 (ii).] Moulded bonded articles, such as abrasive wheels and refractory articles, are made by placing in a mould an oversupply of a mix containing granular material and bond, applying to the mix in the mould a preliminary consolidating pressure which is substantially uniform over different small parts of the area of the surface of the mix by means of a deformable pressing member capable of conforming to the irregularities of the surface of the mix, removing excess mix and further consolidating the article under comparatively heavy pressure. The preliminary consolidating pressure may be employed in conjunction with a jolting of the mix as described in Specification 394,668. The final consolidation may be carried out so that a predetermined volume of the mix in the mould is consolidated to a predetermined volume, e.g. by means of a stop mould. Abrasive wheels may be made in the apparatus shown which includes a mould comprising a body ring 3, a strike-off ring 4, a base plate 5 and a central post 6 for forming the arbor hole in the abrasive wheel. The deformable pressing member may comprise a rubber bag 25, Fig. 1, held in place by a metal cap 24 secured to the top of the mould, the bag 25 having a supply tube 26 connected to a suitable source of fluid, e.g. air under pressure. Instead of applying a fluid pressure to the bag a closed fluid pressure cushion 41, Fig. 2, may be used, weights 42 imparting the desired pressures. After the material in the mould has been subjected to the preliminary consolidating pressure the strike-off ring 4 is removed, the top surface of the mix levelled off with a straight edge to remove the excess mix and the remaining mix subjected to the final consolidating pressure by means of a plunger. Specification 394,667 is also referred to.

IPC: F16D43/26
Filed: 1953-11-16
Abstract: 782,154. Fuze-setting apparatus. ELLIOTT BROS. (LONDON), Ltd. Nov. 16, 1954 [Nov. 16, 1953], No. 31758/53. Class 9(1) A clutch device for fuzesetting apparatus as in Specification 578,330 comprises an annular driven element 1 adapted to engage the movable part of a projectile fuze and having an arm 2 extending between coaxial annular elements 3, 4. The element 4, which may be angularly adjusted by means of peripheral teeth 8 is coupled to the element 3 by a U-shaped member 9 pivoted on the arm 2 and provided with pins 10, 11 engaged in grooves 12, 13 in the elements 3, 4 respectively. The element 3 is keyed to an annular coupling 14 which is keyed to a hollow driving shaft 17. A motor (not shown) is so connected to the shaft, that the shaft may be periodically rotated from a fixed starting position through part of a revolution and returned to the starting position. The leading end of each groove 12. 13 in the direction of rotation has a radial extension, the ex-- temsion 12a (not shown) being in the opposite sense to extension 13a and each extension merging with the main groove through a smooth curve. The pins 10, 11 are so placed that when pin 10 is engaged in the extension 12a, pin 11 is received in the groove 13. Thus by setting the stop element 4 so that the extension 13a is angularly displaced from extension 12a by the angle through which the driven element 1 is to be rotated, rotation of the driving element 3 by means of the shaft 17 will rotate the element 1 until pin 11 enters the extension 13a. The coupling member 9 then swings inwards about its pivot and moves the pin 10 out of the extension 12a into the main groove 13, thus discontinuing the drive from the shaft 17, while the driven element 1 is adjusted by the continuously adjusted stop means 4 to adjust the setting of the fuze element. When the shaft 17 makes its return rotation, the pin 11 is forced out of the extension 13a and the driven element 1 is again locked to the diving element 3.

Abstract: 205,777. Corona Typewriter Co., Inc., (Assignees of Petermann, 0.). Oct. 21, 1922, [Convention date]. Ink-ribbon mechanism. - Automatic feed-reversal mechanism comprises worm gears carrying axially arranged spool-holders slidable and rotatable upon stationary posts, driving-worms rotated bv pawls and ratchets actuated by the keys, and means operable automatically bv an obstruction on the ribbon for disengaging the gear of the full spool and engaging the gear of the empty spool. The mechanism is described as applied to a machine having a folding platen carriage on pivoted arms 6, Figs. 3 and 12. The barrels 40 of single-headed spools 41 are frictionally gripped upon split sockets on the hubs 63 of worm-wheels 64 freely mounted upon two vertical posts 45 on brackets 43 carried on the arms 6. Spool cups 58 secured at 60 to lugs bent up from the brackets 43 are provided with axial openings 59 to allow the wheel hubs 63 to slide up and down within them. The driving-worms 52 are keyed on shafts 51 provided with ratchet wheels 53, Fig. 6, engaged by pawls 34 pivotally carried at both ends of a rocking bar 30 linked to the universal bar of the machine and actuating the feed on its forward return swing. Pivoted on the shafts 51, between the ends of the worms 52 and the shaft bearings, are U-shaped yoke members 68 with central upwardly-projecting lugs 69 and downwardly-projecting lugs 77. The lugs 77 are inclined or cammed at their rear edge 77<a> to coact with a slot 76 in the forward arm 70 of bell-crank reversing-levers pivoted at 74 to the brackets 43. The arms 71 of the reversing-levers are connected by a transverse wire link 86, the rearward movement of the arm 70 of one producing a forward movement of the corresponding arm of the other. The vertical spool shafts stand within the arms of the yokes 68, Fig. 12, so that when a crank arm 70 is moved rearward the slot 76 receives the lug 77 and the yoke drops, allowing the wormwheel 64 to engage the worm 52. The worm gear of the other spool is thrown out of engagement by the forward movement of its crank arm, the rear edge of the slot 76 engaging the cam edge 77<a> and tilting the yoke, thereby pushing up the worm-wheel 64. The crank arm 70 associated with an empty spool is pulled rearward when a trip lever 79 pivoted to a downwardly bent extension 78 of the arm is pulled into the path of a reciprocating hook 84 carried by the rocking bar 30. The trip lever has a wire loop 85 at its upper end through which the ribbon 38 passes, and is normally held vertically by a weight 82 until an eyelet 39 near the end of the ribbon bears against it and pulls the lower end of the trip lever into the path of the hook 84 which engages it on the next depression of a key on the spacebar.

Abstract: 1,239,970. Ultrasonic inspection devices. DR. J.U.H. KRAUTKRAMER GES. FUR ELEKTROPHYSIK. 5 July, 1968 [31 Oct., 1967], No. 32146/68. Heading H4D. In an ultrasonic pulse-echo inspection method for evaluating the magnitude of test specimen defects in terms of the size of equivalent discshaped reference flaws, and for locating defect positions, a cathode-ray tube (C.R.T.) provides an echo display, a transparent graph bearing a time-base scale and also DGS curves relating the echo amplitudes of such reference flaws to their sizes S and their distances D from a transducer probe is placed in front of the C.R.T. screen, the gain G of the ultrasonic inspection apparatus is first adjusted to bring the height of a displayed echo from a reference reflector block to a predetermined mark on the graph and secondly is raised a predetermined amount necessary for setting correct the heights of test specimen echoes in relation to the echo heights of said reference flaws on the curves, the equivalent flaw size of a test specimen defect is then determined from whichever curve is just reached by the peak of the displayed defect echo, and the defect position is determined from the position of its echo on the time-base scale. In the Fig. 2 embodiment plastics sheet 18 bears echo amplitude/distance (DGS) curves 40, 41 . . . 45 for reference flaws of 8, 6. . . 1À5 mm. diameter in a particular material. Plastics sheet 19 bears a distance scale 6 oriented along the C.R.T. time-base. R1 is a reference mark representing the height of the back-wall echo from a reference reflector block (approximating an infinite reflector), but plotted 30 dB below its true position. To calibrate the apparatus for testing, the gain is adjusted to bring this back-wall echo up to R1, then is increased by 30 dB. The slopes of the DGS curves may be altered to take into account the ultrasonic attenuation of different test materials, and a curve 11 for an assumed attenuation-free material may be drawn for evaluating gain corrections to take into account losses by roughness and curvature of a test specimen.
