Title: An improved method and apparatus for burning solid fuels
IPC: F23H7/06
Filed: 1920-04-14
Abstract: 164,914. Martin, J. April 14, 1920. Grates; refuse fuel, furnaces for burning; fuel, feeding.-Solid fuels, particularly those not readily ignitible, or which are mixed with or produce much slag, such as coke with residues from the coking process, or garbage, are burnt in a furnace in which the fuel is continuously separated on an ignition grate within the heating range of the main grate, the finer particles falling through on to the latter whilst the coarser particles are retained longer on the ignition grate before falling in an ignited state on to the main grate, which is of step form and has mechanical means for breaking up the fuel. In the furnace shown, fuel is fed from a hopper 1, e.g. by a feed-screw 3, Fig. 4, to the ignition grate 4, the bars 5 of which project over the main grate and are longitudinally adjustable so that the projection may be varied, by which means the coarse partides may be retained for a greater or less time on the ignition grate. The bars are rocked by a shaking device such as the eccentric 7. A second charging device 8 may supply solid or liquid fuel to the main fuel. The main grate consists of U-shaped members forming hollow and perforated steps 9 with hollow side portions 10, through which air is supplied from pipes 12, the supply to individual steps being controlled by valves 13, which may be connected for operation in groups. Between the steps are pusher grates 15, 16, which are alternately connected to bars 17, 18 by which they are given reciprocating motions over the steps, adjacent grates thus moving in opposite directions. The slag passes out beneath a curtain 24 forming an air-seal and consisting of a number of hanging plates or doors 25, Fig. 5, arranged side by side, each having side wings 26 and a plate 30 hinged at its bottom. The slag passes into a collector 22 and pre-heats air for combustion which is drawn through the collector by a fan 33. The slag may be automatically discharged from the collector 22 in accordance either with the quantity of slag or its temperature. Part of the air may also pass through a heater 35 and be supplied by a pipe 36 to beneath the ignition grate 4.

Filed: 1925-04-22
Abstract: 255,525. Carlisle, D. W. April 22, 1925. Addition to 232,340. Apparatus for signalling one of a number of possible indications.-In an electric signalling system of the type described in the parent Specification wherein an indicator band is operated by reversible ratchet mechanism, the ratchet mechanism is controlled by a manually operated switchboard. As shown in Fig. 4, the indicator comprises a band H mounted upon drums F, G and controlled through ratchet-and-pawl mechanism by two solenoids A, B which are respectively connected to pairs of contacts p, p<1> arranged in parallel on a switchboard R. The arrangement is such that when a contact m co-operating with the pairs of contacts p, p<1> is moved downwardly the solenoids A, B are energized intermittently in sequence. The solenoid A moves a pawl D into engagement with a ratchet E and the solenoid B moves the band through a number of steps corresponding to the number of pairs of contacts p, p<1> which are operated. When the contact m is moved upwardly, the solenoid B is energized prior to the solenoid A and the band 11 is moved in the reverse direction when the solenoid B is de-energized. Several indicator bands may be arranged as a single unit so that a number comprising several digits or a word may be displayed. In this case each indicator is operated by an independent set of contacts p, p', all of which are mounted on a common board R. Each movable contact m may be operated through a pinion m<5> and a rack N<1> by a knob m<4> or may be slidably mounted on a bar. The knob m<4> has a pointer m<7> which co-operates with indications on the switchboard panel. In a modification, the switchboard comprises a contact arm M adapted to be rotated by a pinion m<5> which engages a circular rack N<2>. A plurality of indicating instruments may be connected in parallel and a bell may be operated when the indication is changed.

Patent GB-1060833-A (GB)
Title: A method of manufacturing fuel elements
Inventor: SMITH SAMUEL SPENCELEY
IPC: G21C3/20
Filed: 1964-03-13
Abstract: A fuel element is made by embedding a uranium rod in magnesium powder and heating the rod and magnesium in an inert atmosphere to a temperature at which the magnesium reduces a film of oxide on the surface of the uranium and is deposited as a coating on the surface. The deposition of magnesium is believed to occur by vapour phase transfer.  Instead of magnesium powder, a suitable magnesium alloy powder such as Magnox may be used.  By coating the uranium rod with magnesium, the rate of oxidation in carbon dioxide at elevated temperatures is significantly reduced. Prior to embedding the rod in the magnesium powder, it should preferably be cleaned and decarburized as described in Specification 1,060,832, and its surface may be chemically or mechanically roughened to improve keying of the coating to the surface.  The film of oxide on the surface may be that which occurs naturally, but if desired, the rod may be anodized before embedding in the magnesium powder in order to provide a thicker film of oxide.  The anodizing electrolyte consists of ammonia, water, and ethylene glycol.  Facility of deposition of the magnesium on the surface of the rod is increased by the presence of uranium tetrabromide in the inert gas stream in which the rod is heated.  The inert gas, preferably argon, must be dry and of high purity.  No moisture should be present in the magnesium powder and thorough drying immediately prior to use is essential.  Degassing under vacuum is necessary for all materials which could introduce undesirable impurities into the gas stream.  In one example, a tantalum container with the uranium rod embedded in magnesium powder is heated in a tube furnace connected to the supply of purified argon for 1 hour at a temperature of 700 DEG C.  The coated rod is placed in a magnesium or Magnox can to which it is united by autogenous welding.  This should be carried out at a temperature well below the melting point of magnesium, preferably not greater than 450 DEG C. in order to prevent grain growth in the canning material, by the simultaneous application of heat and isostatic pressure. The rod may, for example, be enclosed in its can by welding a plug in the open ends of the can, the interior of the can evacuated through a tube provided in the plug and the tube sealed off.  The assembly is then placed in an autoclave, preferably having an inert gas or carbon dioxide atmosphere, and heated to the desired welding temperature under pressure to effect welding.  In one example, the assembly was heated at a temperature of 450 DEG C. for 100 hours at a isostatic pressure of 1 1/4 tons/sq. inch.

The cells 14 are mounted in individual compartments 16 formed by radial walls 20 extending between the inner wall 18 and outer wall of a plastics container 12, the top of each cell being located in a recess 22. A hole 30 extends through the top of the container 12 above each cell and receives a cell post 26 which may be moved downwards to deflect the diaphragm. The actuating means for each cell comprises a plunger 28 biased by a spring 34 held under compression by a cap 82 screwed at 80 into the container cover 74. Normally, all the plungers 28 are held retracted by a common retaining ring 36 having lugs 36B locating under flanges 28D. A small clockwise rotation of the ring 36 releases the plungers simultaneously to engage the posts 26 and activate the cells. The ring 36 is rotated by rotating a nut 45A which is axially immovable and which engages a screwed rod 48 connected to an arm 36A. An upstanding rib 42 prevents unwanted movement of the ring 36 by obstructing the arm 36A, this rib being broken to permit the ring rotation.

Abstract: 513,532. Delivering blanks from hoppers. BIRKIGT, M. April 8,1938, No. 10780. Convention date, March 12. [Class 78 (i)] [Also in Group XXII] In an automatic machine tool such as a drilling- machine, blanks from a feed shoot are transferred to working position by means of two reciprocating parts whereof the first supports the blanks in the shoot until it is withdrawn to allow a blank to fall on the second part which supports it during the working operation and is then withdrawn to allow the finished blank to be ejected. As applied to the drilling of two opposed holes of differing size in the sleeves 1 forming inertia weights for shell fuses, by means of drills 4, 4<1>, Fig. 2, the blanks are stacked vertically in a shoot 3, which has projections 3, 3", Fig. 5, at the top adapted to co-act with a flange at the base of each blank in order to ensure that the blanks will be placed the right way up in the shoot by hand. The reciprocating parts consist of upper and lower plungers 8, 7 pressed forwardly by springs 12, 13, and periodically retracted by levers 14, 15, tappets 17, and cams 19, 20 on a shaft 21. The lowermost blank 1 rests on the plunger 8 until the latter is retracted, whereupon it falls on to the plunger 7. On the next forward stroke the plunger 8 yieldingly presses the blank against a stop m which positions it accurately in line with the drills 4, 4<1>, a spring r holding it down on the plunger 7. On the next retractive stroke the plunger 8 releases the drilled blank and the plunger 7 is then withdrawn from beneath it, allowing it to fall down a discharge shoot 6. The cams are arranged so that the plunger 7 lags behind the plunger 8. The plungers may be replaced by oscillating members.
