Title: Waste-heat boiler with slag-catching device
Inventor: KEMMETMULLER ROLAND
IPC: C21C5/40
Filed: 1960-05-02
Abstract: 942,262. Waste heat steam boilers; metallurgical converter chimneys and hoods. WAAGNER-BIRO A.G. May 2, 1960, No. 15399/60. Headings F4A, F4B, F4J and F4X. A waste-heat boiler for utilizing the heat of the blow gases from a Bessemer converter 8 operating on the basic process is disposed in a flue 3, the upper part of which serving to convey the gases to atmosphere being closed by a damper 10. The flue is divided by a partition wall into an up-pass constituting a radiation chamber 1 which is lined with contacting generating tubes and a downpass locating convectively heated surfaces 2. From the bottom of the downpass which contains a wet filter 12, the gases ascend in a third pass containing further wet filters 15 to an exhaust fan which delivers them into a stack 11. Water from the filters collects in funnels 5 and flows from the funnels to dust recovery plant, not shown. To prevent the boiler heating surfaces from being fouled by slag entrained in the blow gases a screen 4 of tubes is arranged across the boiler inlet so that the gases impinge thereon. The screen consists of several rows of tubes arranged in staggered formation, each tube consisting, as shown in Fig. 6, of an outer tube 13 within which is coaxially disposed an inner tube 14 extending almost to the closed bottom of the outer tube. Water flows down the inner tube whilst steam and/or water discharges from the outer tube, the screen tubes being included in the circulatory flow of the boiler. To dislodge slag accumulating on the screen the tubes are suspended so that they can swing freely, the gas flow causing them to collide so that deposited slag is dislodged and falls on to a watercooled travelling grate 7 whereon it is quenched and carried to slag-processing plant. The tubes can also be swung mechanically or vibrated for example by a pulsating supply of water thereto, to cause the slag to be dislodged.

Title: Apparatus and method for extrusion of plastic net
IPC: B29C48/05
Filed: 1973-03-31
Abstract: 1384187 Controlling net extrusion dies CONWED CORP 31 March 1973 15594/73 Heading B5A [Also in Divisions D1 and G3] A net-like structure of plastics material is produced by extrusion from a head comprising a fixed part 12 (having a tapered hole with grooves in its wall) and a co-operating part 24 which is reciprocated between first and second positions by an hydraulic actuator 28 controlled in response to an electrical signal by a servo mechanism 72, 44. In the first position of 24 it fully or nearly abuts the part 12, so causing the extrusion of longitudinal threads 16, Fig. 9, or such threads superimposed on a thin web, while in the second position an appreciable gap is formed to produce a transverse thread 22. The position of the actuator is monitored by a transducer 80 which feeds back a signal for comparison at 70 with a desired position signal on a switch 68. The desired position signal is produced at least by a function generator 64. This may comprise an oscillator producing a sine or sawtooth wave form, or a generator, producing a voltage which varies in any desired manner with time. It may be combined with a D.C. bias signal from 66 and there may be a similar pair of generators 64A,67 with a timer 88 operating switch 68 to alternate between the pairs. Typical waveforms are illustrated together with the resulting form of the net. That shown in Fig. 9 is produced by a sine wave from 64 (signal A) alternating with D.C. from 67 (signal B). Seven other examples are illustrated.
