Abstract: 277,325. Hornsey, J. W. Sept. 8, 1926, [Convention date]. Rotary furnaces; charging and discharging; cooling discharged materials.-A furnace plant for the direct production of iron, or for the reduction of oxide ones, such as those of zinc, lead, and copper, comprises a preheater 1, a reducing chamber 24, and a cooler 47, all of the rotary type, the drums being mounted loosely in fixed end heads and escape of gas being prevented by sealing devices, such as 9, 17, &c. In connection with each seal is provided a pocket 10 with a. screw conveyer 11 for collecting and removing dust. The ore is fed to the upper end of the drum 1 by a conveyer 12 passing through the end head 8. and is delivered therefrom into a channel 20 in the intermediate head 26, from which it passes through a grating 22 to a screw conveyer 23 opening into the upper end of the reducing-drum 24. By this arrangement the ore and heating-gases are kept out of contact during transfer from one drum to the other. The conveyer 23 has four concentric casings 29 --32. Fig. 3, of which the three innermost are spaced as shown to form passages for the circulation of cooling-water, and a heat-insulating space. Alongside the ore conveyer is a second conveyer 28 for powdered coal, and beneath the junction between the drum 24 and the head 26 is arranged a dust pocket 36. At the lower end of the drum 24 the reduced charge passes over a lip 37 into a channel 42 in the head 38, and is delivered by the conveyer 44 to the cooler 47, on to the outer surface of which water is allowed to fall from an overflow trough 52 with notched edges. The upper ends of the preheater and cooler have helical ribs 13. 48 for preventing accumulation of the charge at the point of delivery. Reducing gases are supplied to the reducing drum through the port 45, and surplus gas is burnt in the preheater with air supplied through water-cooled nozzles 15, ignition being effected by a blower delivering through the port 27. Inspection ports and manholes are provided in the various fixed heads, and in the uppermost dust is collected in a pocket 4, and the gases pass over a baffle 3 to the stack. In a modification transfer of the charge between the drums, is effected through inclined shoots, and dust is removed from the pockets 10 of the seals by a double bell device. Specification 284,040, [Class 72, Iron &c.], is referred to.

Title: High speed multichannel recorder
Inventor: SCHMOLL RONALD HENRY
IPC: G01D9/24
Filed: 1971-04-19
Abstract: 1287716 Recording-apparatus CLEVITE CORP 19 April 1971 [19 March 1970] 23354/71 Heading G1J [Also in Divisions B6 and G4] In a chart recorder in which the values of signals on a plurality of input circuits 20-1... 20-8 are marked on a moving chart 1 successively and repetitively, the resulting intermittent traces relating to the respective input circuits are provided with gaps which identify the circuits they relate to by their position. A pulse generator 25 drives a sequencer 23 (ring counter arrangement) which gates the input circuits 20-1...20-8 at commutator 22 via line 13 to position a pen 14 transversely to the direction of chart movement 2. Some input circuits may be selected more frequently than others, or some may be skipped. Each pulse from generator 25 is delayed at 73 and passed via an AND gate 38 (if this is open) to energize a solenoid 69 in actuator 26 to lower the pen on to the chart 1 to mark a dot. Sprocket holes 7 and notches 82 in chart 1 are sensed photo-electrically to drive and reset-to-zero, respectively, a counter in a comparator block 34, the count being decoded and compared with an indication on lines 35 from commutator 22 of which input circuit 20-1...20-8 is currently selected. Comparator 34 holds gate 38 open except on equality in the comparison, so that for each input circuit, marking of the chart is prevented at respective positions, which are identified by preprinted numbers along the margin of the chart e.g. for input circuit 20-1 a gap will cover at each position marked "1" e.g. 29-1. A switch permits recording without gaps. Actuator 26 does not interfere with transverse movement of pen 14, glass 67 on the pen sliding along molybdenum disulphide filled nylon insert 66 in actuator 26. The pen tip 10 uses a bundle of plastics fibres through which the ink from reservoir 16 flows by capillary action. (For figure see next page)

The apparatus is used for cutting the web of the joist along a castellated line, thereby dividing it into two similar parts. The lower carriage has four wheels 15 arranged to run on the flanges 17 of the joist and which are stepped to suit different standard sizes of joist to be cut. The front wheels are mounted on an axle 13 driven by an electric motor 22 through a friction drive 24, gear-box 23 and chain 25. Alternatively the lower carriage may be attached to a tractor driven by an electric motor and adapted to run on the supporting joist. The rear wheels on the axle 14 are driven only by frictional engagement with the flanges. The upper carriage 11 has four wheels 30 running along transverse tracks and is driven along them by the engagement of a follower 33 in a cam groove 34 of a cylinder 35 driven through gearing 37, 38 from the rear axle 14. The oxy-acetylene cutting- torch 41 is carried by brackets 39, 40 from the upper carriage. The cam groove has two spiral portions with intermediate arcuate portions to provide the dwells; different cylinders 35 are used for cutting castellations in different sizes of joist. Two or more cutting torches may be mounted on the upper carriage for cutting a corresponding number of joists arranged sideby-side. The apparatus may be used to cut the joist into two wedge-shaped castellated portions by disposing the joist obliquely to another joist along which the lower carriage travels. For making an apertured beam, Fig. 5, the two parts of the cut joist are welded together at the tips of the castellations.

Abstract: 889,531. Winding grid electrodes. STANDARD TELEPHONES & CABLES Ltd. July 22, 1958, No. 23456/58. Addition to 773,044. Class 83 (4). A machine for winding individual grid wires in accordance with the method claimed in Claim 3 of the parent Specification includes a clutch whose operation couples the said one mandrel to means for rotating the mandrel about its longitudinal axis and for moving it along said axis during rotation and a cam which controls the operation of the clutch, which cam includes a first part operable to cause a substantially instantaneous engagement of the clutch as the mandrel attains the said particular position, and a second part operable to cause a substantially instantaneous disengagement of the clutch when the required number of turns of the grid have been wound. A shaft 1, upon which a mandrel for winding a grid is mounted, is itself mounted in bearings 2, 3 and is urged away from the bearing 3 by a spring 4 acting on a clutch plate 5. The shaft 1 is rotated and moved axially by a splined shaft 6, having a clutch plate 9, adapted to engage the plate 5, slidable in a sleeve 7 rotated by a gear 12. The shaft 6 is urged away from the shaft 1 by a spring 10 and bears at its lower end on a bar 11 resting by means of a pin 13 on a cam 14 rotated by means engaging gear teeth 16. In operation, as the cam 14 moves from right to left, the pin 13 first drops on to a platform 17, carried by the cam 14, held down against a compression spring 21 by a guide plate 23. As the platform 17 moves beyond the plate 23 it is raised by the spring 21 to lift the pin 13 and thus bring the clutch plates 5 and 9 into engagement. The shaft 1 is thus rotated, and moved axially by the cam 14, until the pin 13 rises on to a platform 19 carried by the cam 14 and held up, against a tension spring 22, by a guide plate 24. As the platform 19 leaves the plate 24 the spring 22 pulls it down to allow the spring 10 to disengage the clutch plates 5 and 9 and the spring 4 to lower the shaft 1. At the same time gear means 26 causes a cam 25 to engage an arcuate slot in the shaft 1 to brake it. The clutch plates 5, 9 may have teeth.

Abstract: 1,147,467. Photo-electric length measurement using radiation interferences. CARL ZEISS JENA VEB. May 26, 1966, No.23587/66. Heading G1A. In a machine which rules or measures lengths by photo-electrically scanning radiation interferences the source of radiation is tuned to a wavelength which is an integral fraction of a statutory unit of length; the desired wavelength may be produced by an interferometric or beat-frequency comparison with a standard wavelength radiation source. Two interference plates 2 are fixed to the bed and slide of the machine respectively and as the slide moves the interferences are counted by a photo-electric receiver 3 and counter 4 as a measure of the slide's movement. The source of radiation which is a laser, is compared with a standard krypton source 8 by an interferometer system 10, comprising two inter-connected Fabry-Perot interferometers, which automatically tunes the laser to the desired wavelength. Tuning may be effected by adjusting the pressure of the laser. Alternatively one laser may be tuned to the standard source and a second laser tuned to the desired wavelength by noting the beat-frequency of the pair.
