Title: Method and apparatus for the incineration of sludge
IPC: F23G5/38
Filed: 1975-08-15
Abstract: 1494946 Incinerators for chromium wastes CHUGAIRO KOGYO KAISHA Ltd 15 Aug 1975 [20 Aug 1974] 34120/75 Heading F4B Sludge containing chromium compounds is incinerated to form ashes, the ashes then being subjected to a reducing atmosphere at a high temperature to reduce hexavalent chromium to the trivalent form, the ashes then being cooled under conditions which do not allow the reoxidation of the chromium. The incinerator, Fig. 2, may comprise a chamber 1, forming the incinerating zone A, having a feed opening 7 for the sludge, burners 10 producing a hot, oxydizing atmosphere to convert the sludge to ashes, a second chamber 18 supplied with a reducing atmosphere, and forming the reducing zone B, where hexavalent chromium compounds are converted to a trivalent form, and a third chamber 21 forming cooling zone C where the residue is so cooled as to prevent reconversion to the hexavalent form. Hexavalent chromium compounds, being soluble, are more dangerous as pollutants than the trivalent form. To obtain the oxydizing atmosphere in chamber 1 the burners 10 are supplied with sufficient or more than sufficient air. The chamber is divided by a series of horizontal grates 5 with peripheral openings which are staggered vertically, the sludge passing from higher to lower grates and being stirred meanwhile by rabble arms 6. The residual ash passes out of chamber 1 through opening 17 and falls on to a conveyer 20 in chamber 18 where it is subjected to hot reducing gases from a burner 19 supplied with insufficient air for complete combustion. A pipe 24 recirculates some of the waste gases from the top of the incinerator into the middle of the chamber. Another pipe 25 takes air heated by cooling the ash in chamber 21 to the chamber 1 to conserve the heat. After being cooled the ashes leave the chamber 21 at 22 and are disposed of. In addition to the burner 19 a reducing gas D generator may be provided feeding reducing gas through the cooling chamber 21, where it is heated, into the reducing chamber. The generator D uses a burner, the combustion products of which may be passed to the incinerating chamber over pipe 28. Another pipe 29 may take the exhaust gases from the reducing chamber 18 to the incinerator chamber. In other forms, Fig. 3 (not shown), and Fig. 4 the reducing and cooling operations are carried out in lower parts of the same chamber 1 as the incineration, the ash passing from the lowermost grate of the incinerator A on to a grate of the reducing section B to where it is subjected to reducing gases from burner 19 and generator D. After passing over a second grate in section B the ash falls into the cooling section C before passing out at 17. The incineration zone A may alternatively comprise a rotary kiln with direct heating burners and the reduction zone B may also be a rotary furnace.

Title: An Offset Control System for Traffic Signals
IPC: G08G1/081
Filed: 1967-07-26
Abstract: 1,167,399. Road traffic signals. TATEISI ELECTRONICS CO. 26 July, 1967 [29 July, 1966], No. 34301/67. Heading G4Q. Clock pulses from a master controller are received at terminal 10, Fig. 1A and counted in counter C 1  which feeds decimal counters C 2  and C 3  which provide an output on line L 3  indicating one point in the cycle at which a change of signals is required. The stages of counters C 2  and C 3  are connected to a matrix MX 1  comprising pinboards adapted to provide three outputs, one of which is selected by a " split " signal received from the master controller on one of lines ST 1 -ST 3  thereby providing an output on line L 4  indicating a second point in the cycle at which a change of signals is required. The signals on lines L 3  and L 4  advance a four-stage counter (C 4 , Fig. 18, not shown) and initiate timing of an amber phase through a counter (C 5 ) fed from a local pulse generator (OS 1 ) followed by a further advance of the four-stage counter. The stages of the four-stage counter are coupled through a matrix (MX 2 ) to amplifiers (S1-S 6 ) supplying the signal lamps (IG to 2R). Offset control.-The counters C 2  and C 3  are connected to a matrix MX 5  adapted to provide three outputs, one of which is selected by an " offset " signal received from the master controller on one of lines OT 1 -OT 3  thereby providing an output on line L 5 . The instant when this signal occurs is compared with a desired instant by means of a logic circuit, supplied with three signals on lines L 6 , L 7  and L 14 . The signals on lines L 6 , L 7  are derived from a counter CC 2  supplied with clock pulses from terminal 10; signal L 6  lasts for the first 13% of each cycle and L 7  for all except the first 15% of a cycle. The signal on line L 14  is a square wave synchronizing signal at cycle frequency supplied from the master controller at terminal 12. In accordance with the incidence of the signal L 5  in relation to the other three signals, the gate IN 1  may be closed for a short time or the counter C 1  may be changed from its normal count of 48 to either 42 or 54, thereby shortening or elongating the cycle by 12¢%, and it is shown that this can change to a new offset within four signal cycles. In a modification, Fig. 4 (not shown), the counter C 1  is omitted from the local controller, and instead the master controller provides three sets of clock pulses; the faster or slower set is temporarily selected as described above when a change of offset is required.
