Abstract: 1478542 Incinerators PEXIMAC BV 20 Sept 1974 [28 Sept 1973] 41133/74 Heading F4B An incinerator unit designed to be mounted on a truck has a furnace comprising a stationary casing 7 of sheet steel inside which revolves a rotary grate 8 of frusto-conical shape formed of a number of rings each consisting of a series of overlapping curved members 9 with end flanges 10, 11 Fig. 3, 4 the flanges of adjacent rings being connected by pins 14 with clearance to allow for expansion, the entry of unwanted air being prevented by cover rings 15 also secured to the pins. Clearance is provided between the overlapping parts of adjacent plates to allow for expansion. The members 9 have openings 20 to admit air blown into the space between the grate and the casing 7 by a fan. In another form the grate is built up from a number of rings each formed by an assembly of flat flanged members. In both forms the rings are made up from identical plates, different numbers of plates being assembled to obtain rings of different diameters. The ends of the grate are closed by members 31 and 38 having edges sealed to the casing at 32 and 39. Member 31 carries a drive ring 34 and member 38 runs on rolllers 40. A feed screw 45 feeds refuse from hopper 3 to loading shoot 44 passing through an opening in the end member 38. Burners 41, 42 are controlled to maintain the temperature at the desired level. The products of combustion are passed through a compartment 47 of the casing where there is a burner which is put into operation if the temperature is too low. A succession of other compartments are formed by baffles in duct 48 carrying the combustion gases to dust removal apparatus, e.g. a centrifugal washer, from which they are exhausted to atmosphere. Water is supplied to the washer from a reservoir 50. Ash leaving the incinerator is received in a sheet metal ash pit 5 from which it is removed by scrapers or screw conveyers and by water from the reservoir 50. A spout 54 may be attached when clearing out the ashes. Control means may be provided to prevent excess temperature.

[Also in Division G4] Apparatus for measuring the length of a strip 11 leaving the rollers 10 of a mill comprises a tachometer 14 which emits a number of pulses proportional to the number of rotations of rollers 10. These pulses are transmitted to counters 15, 16 but cannot be used directly as a measure of the length of strip because some slipping occurs. Detectors 17, 18, 19 are used to actuate counters 15, 16 when the leading edge of strip reaches detector 19 and to stop the counter 15 when the leading edge of strip 11 reaches detector 18 and to stop counter 16 when the trailing edge of strip 11 reaches detector 17.
