Title: Improvements in or relating to turning wheel sets in lathes
IPC: B23Q17/22
Filed: 1962-06-27
Abstract: 988,725. Lathes. MASCHINENFABRIK DEUTSCHLAND A.G. June 27, 1962 [July 24, 1961], No. 24732/62. Headings B3B and B3T. A method of turning the wheel rims of railway vehicle wheel-sets comprises rolling the set above a lifting device 2 in a lathe, raising the set automatically to centres 6, testing the set for flaws, measuring it and then machining the wheels in the same lathe. A motor 3 for the worm-driven lifting device 2 is operated automatically to raise the set, after which a beam carrying measuring heads 15, 17 for each wheel is moved axially by a gear 10 until stopped and clamped centrally of the wheels when the line 11 of an optical locating system coincides with an edge 13 on the axle. The axle is first rotated between the centres and tested for flaws by ultrasonic heads 19 positioned hydraulically or mechanically. Simultaneously, a measuring head 24 raised by rack-and-pinion measures the set of the axle, the value being passed through an amplifier and a converter to an indicator, Fig. 5 (not shown). The spacing of the wheels and their offset from the axle midpoint are measured by the heads 15, the measurements being transferred through amplifiers 29, converters and control members 33 to devices 34 for positioning the tool saddles 35, and through control members 31 to follow-up devices 32. A numerical indicator 36 is also provided. The measuring heads 17 are similarly linked to amplifiers 38, converters 39, control members 40, 41, follow-up devices 37 and numerical scales 43 to adjust template carriers 42 for minimum removal of metal, the carriers 42 being adjusted laterally by the devices 34. The measuring heads are retracted automatically before the copy-turning operation is started by a press button. If a flaw is discovered during testing, or the measured points are outside permissible limits, the control members or converters release sound impulses which stop the measuring operation, retract the measuring devices and stop the drive to the centres.

Title: Method of manufacturing lime by burning powered limestone in rotary kilns
IPC: C04B2/10
Filed: 1963-06-21
Abstract: Lime is prepared by burning limestone in a short rotary kiln up to 55 m. in length for 45-180 minutes, the limestone being present in fractions less than 2 mm. in size, optionally together with up to 40% of fractions less than 8 mm. in size, and being preheated to 900 DEG C. in a heat exchanger utilizing the heat of the gases discharged from the kiln.  A multi-stage heat exchanger is described, in which the limestone is entrained upwards in the gases, separated in horizontal cylindrical separators, and falls by gravity to the next stage.  It enters the kiln at 900 DEG  C., and is maintained there at 1000 DEG  C.  The lime may be air-cooled in a fluidized bed, the heated air being then used as secondary air in the kiln.

IPC: C04B7/44
Filed: 1964-06-15
Abstract: In the burning and sintering of cement or other raw materials on a travelling grate, at least a portion of the exhaust gases from the grate are mixed with the combustion air which is passed through the layer of material on the grate to sustain combustion therein, said layer consisting exclusively of a mixture of raw material and finely divided fuel, no sinter returns being added to the raw material.  The exhaust gases are withdrawn from below the grate and the suction box is preferably divided into several compartments, and only the hottest exhaust gases, i.e. those obtained from the compartment adjacent the discharge end, are mixed with the combustion air.

Abstract: 599,226. Gas-blast switches. ENGLISH ELECTRIC CO., Ltd., and ROWLAND, F. G. Sept. 28, 1945, No. 25280. [Class 38(v)] The isolator switch 15, 16 of a gas-blast circuit-breaker is opened in response to pressure of blast gas discharged from the arcing chamber. When the circuit-breaker is opened, compressed air from a reservoir 4 flows through a valve 5, between contacts 1, 2 into an exhaust chamber 7 where it is trapped as in Specification 571,118, the chamber 7 having only small leakage ports 18 to atmosphere. The pressure in the chamber 7 is communicated by a pipe 8 and filter 10 to a cylinder 11 and operates the isolator through a piston 12 and a torque insulator 14. In an alternative construction the cylinder 11 is at the potential of the isolator switch arm and a hollow insulator connects it directly with the chamber 7. A diaphragm-operated relay energising a motor may replace the gas motor 11, 12. The blast valve 5 may alternatively be located in the pipe 8 the leakage ports 18 being omitted. The Provisional Specification refers to a diaphragm operating a control valve for the isolator and also to the incorporation of the invention in a circuit-breaker constructed in accordance with Specification 582,599.
