Title: Improvements in or relating to refuse destructors
IPC: F23G5/00
Filed: 1930-12-06
Abstract: 358,797. Refuse destructors. TUPPEN, G. L., 137, Sule Pagoda Road, Rangoon, Burma, India. Dec. 6, 1930, No. 36859. [Class 51 (i).] A refuse destructor of the type operating below atmospheric pressure and comprising an inclined grate with fixed and moving bars, the refuse being dried before combustion by the waste gases, comprises a combustion chamber 1 and drying chamber 2 together with an inclined grate having fixed bars 3 and movable bars 4 divided into a number of sections, there being means for varying the rate of movement of the material down the grate section by section. In the construction shown the fixed firebars 3, which alternate with the movable bars 4, are supported in slots in inclined racks 5 which are secured to the side walls and divided into sections to allow for expansion. The movable bars 4 are supported on two inclined reciprocating beams 8 divided into sections which may be reciprocated at different rates to vary the rate of movement of the material. As shown, two sections are employed, one extending throughout the drying chamber and the upper part of the combustion chamber, and the other through the remainder of the combustion chamber. The beams 8 carrying the first section are divided at the end wall 14 of the combustion chamber, the two parts being united by narrower members 15. The beams carry brackets 9 supported on rollers resting on fixed brackets 10, and are reciprocated through rods 20 by eccentrics 22, Fig. 1A. Each eccentric is driven by a ratchet wheel 23 intermittently rotated by pawls operated by rods 30 pivoted to arms 34 which are carried on a rocking shaft 35 and operated from a rotating shaft 42 through a crank pin 40 and connecting-rod 37. By altering the position of the pivot pin 38 connecting the rod 37 to the arm 34 the strokes of the moving bars in both grate sections are simultaneously adjusted, whilst the stroke of the bars in one section may be adjusted relatively to that of the remainder by varying the points of connection of the two rods 30 to the arms 34, thereby adjusting the movements of the pawls operating the ratchet wheels. The moving bars may be given a vertical as well as a horizontal movement by suitably forming the brackets 10 on which the rollers move. The portion of the grate in the combustion chamber may be stepped down with respect to the portion in the drying chamber, and the two parts may be of different inclinations. The gases are drawn by an exhaust fan through an arch 55 in one side of the combustion chamber, and may pass through a supplementary furnace or a boiler, or both, on their way to the chimney. A second exhaust fan draws gases from the flue and delivers them through inlets 62 to the drying chamber, from which they pass through outlets 63 back to the flue. Baffles 66 pivoted to the lower edges of fixed baffles 68 rest on the surface of the material and force the gases to penetrate into it during their passage through the drying chamber.

Abstract: 625,459. Detecting faults. DUBILIER CONDENSER CO, (1925), Ltd. (Dubilier, W.). Dec. 20, 1946, No. 37517. [Class 37] [Also in Groups II and XXX] Apparatus for testing and classifying pieces of electrical insulating material comprises a pick-up device which picks up each piece individually, transfers it to a testing point and releases it or carries it from the testing point according to the results of the test. Discs 1, Fig. 1, of insulating material are stored in containers 2 and are pressed upwards by cylinders 5, Fig. 3, under the action of weights 6. Each container 2 has a co-operating pickoff comprising a suction head 12 which is moved downwards to suck-off the top disc and lift it. The suction heads 12 are pivoted at 14 to a beam 13, slidable in a slot 19 oscillated about a pivot 16 by a lever 17 which is vertically reciprocated by cam 21 on the main driving shaft 22. The suction head, having picked off a disc is thus lifted by lever 17 and is withdrawn by the action of cam 29, beam 26 and slider 23 to carry the disc 1 to test station 10 where the suction head is lowered. In this position, the disc is subjected to a high potential, and if it passes this test, the suction-head is lifted to carry the disc 1 over container 32, where the low pressure in the suction head is released to allow the disc to fall in the accept container. If, however, the disc fails, the current passing through the disc actuates a relay to release the low pressure in the suction head so that when the suction head is lifted and moved over container 32, the disc is left behind. Any discs left on the testing stations 10 are removed to a reject container by being blown off by an air jet, Figs. 11, 12 (not shown), or by rotation of the test stations about their horizontal axis, Fig. 14 (not shown), or by tilting the test stations, Fig. 15 (not shown). In a further modification, the discs left at the testing stations are removed by an endless conveyer belt ; the belt 76, Fig. 13, is intermittently moved over shaft 84, belt 83, bevel gears 79 from a sprocket 78 rotated intermittently by a continuously driven Geneva drive 77 mounted on shaft 22. At the conclusion of the test, the suction head is moved forward over the test station to pick-off another disc 1.
