Convention date, Feb. 26, 1932. [Class 83 (i).] The mouthpiece of the metal-pot of a casting- machine is so constructed that the amount of air to be displaced by the molten metal during the casting is reduced to a minimum, and that the mouthpiece is maintained at the same temperature as the molten metal. The arrangement is described as applied to the machine described in Specification 29058/10, [Class 100 (iii), Type making &c.], in which the pot 10, Fig. 1, is connected by a hinge 22 to a rotatable pivot member 23, so as to be movable upwards into contact with the mould 21 and, after the casting, to be swung laterally to shear off the metal. The mouthpiece 13, Figs. 4 and 8, comprises a plate-like portion 24, which is adapted to fit against the upper surface of the throat 12, and a depending fin-portion 27, which extends down into the throat, so as to be in contact with the molten metal when the pot is tilted downwards, and, preferably, at all times. The passage 28 through the mouthpiece tapers in width from the lower end to the plate portion 24, and is preferably flared upwardly in the direction of its length, as shown in Fig. 1. The mouthpiece may be in two longitudinal sections riveted together. The fin 27 reduces the amount of air to be displaced, and also conducts heat to the plate portion 24. To permit the escape of the air normally contained in the mould, grooves 34, Fig. 8, are formed in the upper surface of the mouthpiece on either side of the passage 28 and out of communication therewith.

Abstract: 909,872. Digesters. NORSTEL & TEMPLEWOOD HAWKSLEY Ltd. April 20, 1961 [Feb. 16, 1960], No. 5429/60. Class 64 (1). Raw organic sludge is passed through anon- return valve to a preheating stage and then mixed with steam before passing vertically through a closed reaction vessel, the rate of passage of the sludge through the reaction vessel being regulated so that the emerging sludge is conditioned to the required degree and the level of the sludge is maintained constant in the vessel so that sufficient space is provided for gas given off from the sludge before being vented from the vessel. Sludge is pumped from a container 10 by a variable feed pump 11 through a non-return valve 24 to a heatexchanger 13 to be preheated. The sludge then passes through the pipe 14 to the reaction vessel 15. Steam from a boiler 22 also enters the vessel 15 by the pipe 14. Sludge passes from the vessel 15 via pipes 16 and 17 to the settlement tank 19, but when the plant is first started up then the sludge is recirculated by closing the valve 18 and opening valves 20, 21 and 23, the valve 21 being closed when sufficient sludge has entered the vessel 15. When the operating temperature is reached the valves 21 and 18 are opened and valve 20 closed. Electrical flow gauges (not shown) are connected to the valves 18 and 21 to enable the flow into the plant to be equal to the flow out of the plant. In a modified arrangement a pair of electricallyoperated probes is located within the vessel 15 to adjust the valve 18 so that the level of the sludge in the vessel 15 is constant. Electric probes 25 may also be fitted to the vessel 15 to indicate the level of sludge in the vessel. A gas relief valve 26 is fitted to the vessel 15. Fig. 2 shows the reaction vessel 15 while another embodiment, Fig. 3 (not shown), has an annular baffle depending from the roof of the vessel forming in effect a second vessel with no base. In two other embodiments, Fig. 4 and 5 (not shown), the sludge and steam enter the vessel from the top. Fig. 4 has an horizontal baffle fitted at the end of the pipe 14 and another parallel to and a short distance from 7, while Fig. 5 has an annular baffle. In Fig. 6 a secondary vessel 35 is placed inside vessel 15, and also a conical baffle 36 is provided to deflect the flow in the required direction.
