Title: Process for treating coal
Inventor: GRIFFITHS DAVID MORGAN LUTHER
IPC: C10B19/00
Filed: 1963-08-27
Abstract: Bituminous coal particles are entrained in a carrier gas and passed through a high temperature zone for a period not exceeding 0.01 second, during which the temperature of the coal particles is raised to a value in the range 2000 DEG  to 3000 DEG  C.  The coal, which should be ground to at least -60 B.S.S., preferably -200 B.S.S., may be directly heated by a plasma flame, electric arc, by partial combustion or by mixing with a hot gas which may be the same as the carrier gas, e.g. both may be hydrogen, or the carrier gas may be methane and the heating gas hydrogen.  Alternatively, the coal may be indirectly heated, e.g. in a furnace. The pressure may be above or below atmospheric. The products are cooled rapidly, e.g. by water or liquid hydrocarbon sprays, by a water-cooled surface or by cold gas. Products obtained include acetylene, ethylene, methane and hydrogen. Two examples are described.

Title: Improvements in servo motors and to methods of assembling the same
IPC: B60T13/575
Filed: 1958-10-24
Abstract: 846,056. Fluid-pressure brakes. BENDIX AVIATION CORPORATION. Oct. 24, 1958 [Nov. 27, 1957], No. 34142/58. Class 103 (1). A servomotor has a flowable pressure - transmitting material interposed between the power member and the driven member and pressurized responsive to transmission of force between the members to create a reaction force to oppose actuation of the control device of the servomotor. On brake application, controlmember 56 is moved from seat 74 to first seat atmospheric valve 58 on poppet member 46, supported by diaphragm 50, to seal off chamber 38 from atmosphere via passages 64, 62 and filter 68, and then move member 46 from seat 52 to connect chamber 38 with a vacuum chamber 42 via control-chamber 60. The piston C then moves member D to pressurize master-cylinder A until the desired braking intensity is reached, when rod F is stopped, piston C then moving sufficiently to seat valve seat 52 on member 46 to prevent further pressure decrease in chambei 38.. On brake release, member 56 is moved rearwardly with rod F by spring 80 to open atmospheric valve 58, the master cylinder pressure and spring 76 returning piston C and member D to the release position. To apply a reactive force to member 56, to give the operator " feel," proportional to the force applied to member D, a fluid-filled chamber 82 is formed in a boss 84 of piston C in which projects the member D and a reaction-pin 88 which abuts control-member 56. On braking the piston C pressurizes the fluid in chamber 82 to move member D and to also move pin 88 to oppose the actuating movement of member 56, to give " feel." In assembling the servomotor, the piston C is placed horizontal with the head 94 of pin 88 projecting upwards, the chamber 82 is filled with liquid and member D lowered into the chamber to abut the raised head 94, the member D is then forced into chamber 82 displacing some liquid until it engages the seal 86, further movement pressurizing the liquid to force head 94 against the wall of chamber 82. The master cylinder A and servo casing are then lowered into position and the member D equipped with a washer 16 to operate tilt valve 14, the master cylinder being closed by plug 98. In Fig. 2, not shown, the chamber 82 is formed in member D, and the member 56 has an extension extending into the bore 90 to abut a shorter reaction pin; in assembly, the member D is held vertical and the piston lowered into position. In a further embodiment in Fig. 3, not shown, the fluid chamber formed in a piston boss contains a sliding plug which abuts the member D, the chamber being filled with liquid and the plug inserted to enable the piston to be transported without being assembled with the remainder of the servomotor. Specification 810,167 is referred to.

In an optical maser employing an active medium (e.g. a heliumneon gas mixture) which emits radiation at more than one wavelength, means is provided for spatially dispersing the radiation and for selectively reflecting optical radiation at the desired wavelength through the medium a sufficient number of times to sustain maser operation. The dispersing means may be a prism 7, Fig. 2, and the reflecting means mirrors 5, 6, of which the latter mirror is adjustable about an axis 9; or a reflecting echelon diffraction grating 11, Fig. 4, may form the dispersing means and one of the mirrors, the perpendicular step portions of the grating being an integral number of wavelengths long at the desired operating region. Radiation at the desired wavelength enters and leaves the prism at substantially the Brewster's angle and the angle A of the prism is substantially the supplement of twice the Brewster's angle. For the far infra-red-fed region, window and prism material, for the arrangement of Fig. 2, may be bariumfluoride or calcium fluoride.

The display, Fig. 1, originally has ship A at origon 0 and ship B on collision course L B , being plotted at B1r at time t1 and then at Bor at line to. It is proposed to investigate the change of speed and course of from V A  to V AP  and # A  to # AP . The vector difference between V A  and V AP  when multiplied by a suitable time interval #t can be indicated by # # line S. To cause the sheets's displacement by S, resolver 11, fed with the ship's bearing #A and speed V A  produces orthogonal components of V A , viz. V AX  and V AY . Likewise resolver 13, fed with the proposed bearing and speed, produces components V APX  and V APY . However:- The subtracting of the corresponding pairs of components is done at 15X and 15Y and the multiplication by #t at 16X and 16Y. The two # components of S are fed to orthogonal deflection coils 18. Origon 0 is thus shifted to 0 P  and ship B's last image Bor to Borp. A line from plotted point Bir on sheet 6 down through point Borp by-passes Op at the nearest point of approach distance Cp, indicating that a collision can be avoided.

Filed: 1928-11-23
Abstract: 326,862. Rogers, F. H., (Eclipse Machine Co.). Nov. 23, 1928. Driving-arrangements.- An engine starter for aeroplane or other engines is arranged in axial alignment with the engine crank shaft 40 and provided with a driving member 9 adapted to engage a yielding driven member 45 mounted on the crank shaft and connected thereto by a separate clutch, the member 9 being in axial alignment with the member 45 and adapted to rotate it after disconnection of the primary power source from the member 9. As shown in Fig. 1, the driving and driven members 9, 45 have clutch teeth 14, 47 and the driven member 45 is secured by a ring 46 to a rotatable barrel connected to an extension 41 of the crank shaft 40 through two sets of clutch plates 50, 51 and 56, 57. The plates 50, 51 are arranged to transmit a substantially constant torque, the plates 50 being splined in the barrel 42 and the plates 51 splined to tongues 52 on a nut 49 engaging a threaded sleeve 48 slidable on splines on the shaft extension 41. A spring 53 acts on the plates 50, 51 through a ring 54 and bears against an abutment plate 55 on the extension 41. The clutch plates 56, 57 transmit a variable torque, the plates 56 being splined in the barrel 42 and the plates 57 splined on tongues 58 on the nut 49. A heavy spring 60. interposed between the nut 49 and the plate 55 acts on the clutch plates 56, 57 and its pressure is relieved by the action of the nut 49 when the engine starts. A bevel gear 61 on the barrel 42 drives a bevel gear 62 on the shaft 63 of an electric generator, which is thus driven from the crank shaft 40 through only one set 50, 51 of clutch plates, transmitting a substantially constant torque. The driving clutch member 9 is splined on a shaft 8 and moved axially into engagement with the member 45 by a manually operated rod 11. The shaft 8 is in threaded engagement with a sleeve 17 driven by a hand. actuated shaft 22 through bevel gearing 21, 20. A flywheel 38 coaxial with the shaft 8 and sleeve 17 carries planet wheels 30 each having two sets of teeth in engagement respectively with a fixed internal gear 28 and with internal teeth 27 on a flange 26 on the sleeve 17. The flywheel is set in rotation by means of the shaft 22 and sleeve 17, and the clutch member 9 is then engaged with the member 45 by means of the rod 11.
