Title: Process for the thermal treatment of finely divided solids
Inventor: WHITE FRANK STEVENSON
IPC: C22B1/10
Filed: 1951-09-21
Abstract: A process for heat treating finely divided solids by up-flow of hot gas, which comprises feeding them, as in the apparatus shown, through conduit 38 to a bed 22 of thermally-stable coarser solids resistant to gas entrainment, controlling the velocity of the gas through the bed so as to maintain the thermally-stable solids as a fluidized bed whilst propelling the fine solids upwardly into a freeboard space 23 for discharge to a separator 40, and maintaining the bed at an elevated temperature, is characterized in that the thermally stable solids are of the same chemical composition as the reacted finely divided solids whereby contamination of the latter is avoided.  The heat required in the process may be produced by fuel supplied through conduit 44, or by preheating the fluidizing gas supplied through conduit 29.  If necessary, water for cooling may alternatively be supplied through conduit 44.  Conduit 25 <PICT:0731923/III/1> serves for the supply of the coarser solids, and conduit 27 for fuel for starting up the process.  The level of the bed is controlled by the operation of valves in overflow conduits 32, 34, 36.  The process is applicable to the calcination of calcium carbonate sludges, to the roasting of sulphide ores such as pyrite, to the reduction to magnetite of hematite, and to the treatment of red mud from the Bayer process.  Specification 593,180 is referred to.

Filed: 1954-07-30
Abstract: 789,979. Helicopter control systems. UNITED AIRCRAFT CORPORATION. July 30, 1954 [Aug. 4, 1953], No. 22293/54. Class 4. [Also in Group XXXV] In an automatic aircraft pilot a main servomotor operating a member controlling the position of the aircraft is controlled by the output of a differential linkage separately influenced by a further automatically controlled servomotor and by human pilot-operated means, and the human pilot operated means is also coupled through a lost motion connection to the member controlling the position of the aircraft. An arrangement for controlling a helicopter is described in which the pitch of a main sustaining rotor is varied cyclically or collectively by means of a swash plate which may be controlled automatically (see Group XXXV) through the double servomotor system or may be controlled manually through systems of rods controlling the main servomotor. The pitch of a tail rotor may also be controlled automatically or manually in a similar manner to determine heading. If the fluid pressure supply to the main servomotor fails the lost motion is eliminated automatically. In one arrangement, Fig. 12, for controlling heading, a main servomotor 207a controlling the tail rotor pitch through cables 219 is controlled by a pilot valve 229 which is controlled through a linkage 228 either automatically by a servomotor 222 in response to heading deviations or manually through cables 200. If the fluid pressure supply to servomotor 207a fails, a piston 338 moves to fix link 211 and hence point 208 of linkage 228 so that cables 200 directly operate cables 219.

Title: An improved process for trueing the curved surface of grinding discs for grinding toothed wheels
IPC: B23F23/12
Filed: 1937-08-18
Abstract: 501,021. Trueing grinding - wheels. SOKAL, S. (Zahnradfabrik Friedrichshafen Akt-Ges.) Aug. 18, 1937, No. 22699. [Classes 60 and 124] The tool, for trueing the curved working surface of grinding discs for the grinding of helical toothed wheels, whilst performing a screw motion according to the pitch of the wheel being ground, is guided in zigzag lines over an imaginary surface having the form of a tooth face of the wheel, either in the longitudinal direction of the tooth face or in the direction of the height thereof. As shown, the tool 13 is fitted to a bridge-piece 18 having a ball-joint 19 at one end and a pin 16 at the other end, the pin 16 being guided by a template 15 corresponding to the tooth face. The template 15 and the bar 12 carrying the ball joint 19 are supported by a carrier 10 fitted between the centres 2, 3 of the grinding machine. The centres 2, 3 are mounted on a reciprocable table 24 by head stocks 25, 26. Steel bands 33 are fastened at one end to a drum 34 and at the other end to a slide 30 movable transversely on the table 24 and having a block 31 slidable in a guide 32 inclined to the direction of movement of the table 24. The spindle carrying the drum 34 has a fork 35 engaging a pin 11 on the carrier 10. Thus upon sliding movement of the table the tool 13 will move in a helical path and if the pin 16 is moved over the template 15 the tool 13 will at the same time also move in a curve corresponding to the tooth profile. To permit the tool 13 to trace out a zigzag path in a longitudinal direction of the tooth face, the table 24 is reciprocated by any means and the pin 16 is slowly moved over the template 15, To permit the tool 13 to trace out the zigzag path shown in Fig. '3, the pin 16 is actuated by a lever 23 mechanically geared to the table 24 so that as the lever 23 is reciprocated the table moves step-by-step in one direction. As shown, Figs. 5 and 6, the lever 23 rotates a nut 47 by means of one way clutch members 46, the nut 47 being movable with the table 24 and co-operating with a screw 50 carried by the machine bed 27.

Abstract: 987,989. Rotary engines. KAVERTZ (PROPRIETORY) Ltd. June 23, 1961 [June 29, 1960; May 30, 1961], No. 22911/61. Heading F1F. A rotary prime mover of the geared-vane type, e.g., an I.C. engine operating on a four-stroke, twostroke or diesel cycle, comprises at least two double-winged pistons 7, 8, Fig. 1, rotatable about a common axis in a fixed cylinder 1 having, when operating on a four-stroke cycle, a combustion mixture inlet 2 an exhaust outlet 4 and a spark-plug 6, and a control linkage connecting the pistons which in addition to rotating the pistons about the common axis causes one piston to move relatively to the other to cyclically enlarge and diminish chambers A. B, C and D between the pistons. Opposite chambers A, B are completely sealed off and constitute the working chambers whilst chambers C, D are connected to each other and the outside atmosphere. The inlet 3 and outlet 4 may be closed by appropriately controlled valves as chambers C, D travel past them. The control linkage comprises guide rods 11, 14, Fig. 1a, rigidly connected to hollow and solid shafts 10, 13 respectively on which the pistons 7, 8 are mounted, satellite pinions 12, 15 rotatably mounted on the ends of the rods 11, 14 and riding on a gear-wheel 16 rigidly connected to the cylinder 1 and a crank 18 and crank-rod 19 interconnecting the pinions 12, 15. The crank 18 being rigidly mounted on a shaft 17 on which the pinion 15 is rigidly mounted and the crank-rod 19 articulated on the free end of the crank 18 and the free end of the guide rod 11. On clockwise rotation of the pistons from the Fig. 1, position, the angle between the crank and crank-arm decreases so that the piston 7 closes up on the piston 8 to diminish the volumes of the chambers A, B until in the Fig. 3a position, the crank-rod 19 crosses the guide rod 14 with the chambers A, B at their smallest volume. The chamber A is immediately adjacent the spark-plug 6 and with the combustion gases fully compressed ignition takes place to urge the piston 8 clockwise. Pressure acting on the piston 7 owing to the crossed position of the rods 14, 19 tends to turn the crank 18 also clockwise, the piston 7 then begins to trail the piston 8 so that the chambers A, B gradually increase in volume and spent gases are then exhausted through outlet 4. Compression ratio or ignition timing of the engine may be adjusted by adjustment of the gear-wheel 16, adjusting the length of the crank 18 by the fitting of, e.g., a turnbuckle or by the addition of an eccentric linkage comprising an additional guide rod 12b, Fig. 5a, the replacement of the crank-rod 19 by two rods 19a, 19b a satellite pinion 12c and an adjustable eccentric 12a. The prime mover may be driven by steam power.
