Title: Rotary furnace with planetary cooling tubes
IPC: F27B7/40
Filed: 1971-10-22
Abstract: 1356339 Planetary coolers for rotary kilns KLOCKNER - HUMBOLDT - DEUTZ AG 22 Oct 1971 [29 Jan 1971] 49220/71 Heading F4B Planetary cooling tubes 8 communicate with the interior of a rotary furnace through openings 13 formed in the shell 2 of the furnace, the shell widening conically in the region immediately before the openings, the cooling tube inlets being approximately aligned with the adjacent portion of the shell. The furnace shell is extended by a tube 7 which runs on a bearing 9, 10, the tube 7 carrying supports 26 for the cooling tubes. A fixed tube 12 rumning through the tube 7 is provided with a platform 47 to support a burner lance or other auxiliary devices. In order to accommodate the different thermal expansion of the furnace and cooling tubes the supports 26 allow the cooling tubes to move longitudinally of the tube 7 and the connection 21 between the cooling tube mouth 20 and a connecting piece 18 allows relative movement radially of the connecting piece. The discharge end of each cooling tube is provided with a sieve 34 and baffle 37 arrangement to separate the fines from the discharged material and to direct the sieved coarse material into a crushing plant. The cooling tubes may be partially refractory lined and may be provided with grooves and projections to direct and agitate the material discharged from the furnace.

Title: Improvements in drum sieves
Inventor: HASTRUP NEILS ERIK
IPC: B07B1/18
Filed: 1969-10-09
Abstract: 1,219,529. Rotary sieves. F. L. SMIDTH & CO. A/S. 9 Oct., 1969, No. 49621/69. Addition to 1,156,509. Heading B2H. In a sieve drum 3 of the kind disclosed in the parent specification, the part of the sieve surface of the channel last traversed by the material being sieved, i.e. the part lying between a partition 15 and the end wall 6 of the drum, have openings larger than the preceding part, i.e. the part lying between a partition 14 and the partition 15, and a hopper 13 is provided for collecting tailings passing through these larger openings separately from both fine material that may leave the channel through the smaller openings and the tailings that are discharged through the outlet 20 of the channel. As shown, the openings in the sieve surface between the partitions 14 and 15 are of the same size as those in the main part of the drum. The partitions 14, 15 are formed with openings 16, 17 and walls 18, 19 prevent direct passage of material from opening 16 through opening 17 and from opening 17 through outlet 20. Outlet 20 lies at the inlet end of a spiral tube 21 the other end of which constitutes the discharge outlet for tailings and lies on, or close to, the drum axis. In operation, ground material passes from the mill 1 through an opening 7 into the drum 3. Most of the fine material passes through the main part of the sieve surface 4 into the hopper 9. Tailings mixed with the remainder of the material pass through the opening 16 into the part of the channel between partitions 14 and 15 and the fine material passes through the sieve into the hopper 9. The tailings then pass through the opening 17 into the part of the channel between the partition 15 and the end wall 6. A fine fraction of the tailings passes through the larger openings of the sieve into the hopper 13 and is discarded, and a coarse fraction is discharged via the spiral tube 21 into a hopper 11 and is returned to the mill. The coarse fraction may pass through a magnetic separator so that only metallic grinding bodies are returned to the mill. In a modification, air may be drawn from the tube 21 so as to dedust the coarse fraction discharged therethrough. In this case, the hopper 11 is separate from the casing 8 and is installed directly below the outlet of the tube 21.

Title: Belt drive for spindles
IPC: D01H1/241
Filed: 1965-12-03
Abstract: 1,103,355. Spindle driving. PALITEX PROJECT CO. G.m.b.H. 3 Dec., 1965 [7 Dec., 1964], No. 51464/65. Heading D1D  In a spinning frame having the spindle wharves 4 driven by a belt 1 and pressure rollers 5 located on the opposite side of the belts immediately opposite the wharves 4, as shown, or intermediate the wharves, either the rollers 5 or the wharves 4 are movable towards and away from the belt and such movement is controlled by a common control means responsive to the speed of the belt. Thus the pressure of the belt on the wharve varies with belt speed. As shown belt 1 is driven by a motor 3 having a speed control handwheel 6. Rotation of handwheel 6 causes rotation of a shaft 8 and via cams 9 and cam followers 11 variation in the pressure with which rollers 5 press the belt 1 against the wharves 4. In other forms a pneumatic or hydraulic pump or an electrical generator is coupled to the motor 3 and the resulting pressure or electrical variation;  govern the pressure of rollers 5 on the belt, e.g. through piston-cylinder devices, solenoid or magnetic arrangements. In Fig. 10, not shown, the wharves (4) are mounted on pivoted arms (40) the ends of which are subjected to pressure variation. In Fig. 11, not shown, associated wharves (4) and rollers (5) are each mounted on a pivoted arm (40), (37) between the free ends of which a pressure variation device (35'). (36) is mounted. In Fig. 12, not shown, each wharve (4) is mounted on one end of an arm (43) pivoted beneath the belt and a roller (5) is mounted on the other end of the arm. The inclination of the arm to the belt and thus the pressure of the wharve (4) and roller (5) on opposite sides of the belt is controlled by a pressure variation device (35, 36). In Fig. 13, not shown, the wharve (4) is engaged on opposite sides by oppositely moving runs of the driving belt: an arm (43) is pivoted about the axis of the wharve and carries in opposite ends rollers (5) which urge the two belt runs towards each other under the influence of a pressure variation device (35) acting on arm (43). In another form a speed regulator of the belt driving motor is coupled to a servo transformer which feeds current to solenoids controlling the pressure of the pressure rollers. In a further form the belt drives a centrifugal governor which controls the pressure applying means. Elastic intermediate members, e.g. springs may transmit the pressure to each roller or wharve so that the rollers or wharves may move to adjust to their individual conditions. The means which tension the driving belt may be subject to control by the central pressure controlling means.

Abstract: 1,209,034. Automatic focus control. WELDING INSTITUTE. April 22, 1968 [April 25, 1967; Nov.20, 1967], Nos. 19062/67 and 52726/67. Heading G3R. [Also in Division H1] Focusing of the beam in an electron beam welding apparatus is connected automatically in response to signals from at least one probe which periodically intercepts the beam. In Fig. 1 three probes 13 are supported by a rod 12 from a shaft 10 driven by a motor so that the probes intercept the electron beam (not shown) once each revolution. The output current from the probes when the probes are staggered both horizontally and vertically as shown comprises three pulses Fig. 3 (not shown) the width of which corresponds to the width of the beam at the respective probes and the amplitude of which corresponds to the intensity of the beam. In an alternative arrangement, Fig.2 (not shown), the probes are stationary and the beam is scanned over them. In a modification of this arrangement, Figs.4 and 5 (not shown), the beam is periodically scanned along the boundaries of a quadrant thereby making two passes over an L-shaped probe. The output signals are used to provide automatic control of the current in a focusing coil, and in one arrangement, Fig. 6 (not shown), the peak voltage at each sweep is applied to a maximum voltage sensing device which senses a change of polarity in the slope of the signal resulting from the succession of peak voltages; whenever the polarity changes a signal is applied to a focus servo to adjust the coil current in the required direction. Alternatively the peak voltage may be applied to a null balance servo fed with a reference voltage. The probes are preferably ribbons placed edge on to the beam and may be of tungsten, copper or platinum.
