Abstract: 467,196. Disc mills; stuffing-box substitutes. PREISS, M. Dec. 12, 1935, No. 34459. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 18, 1936.] [Class 59] [Also in Group XXVI] In a disc mill cooling devices for gaseous or liquid medium conduct the medium over the outer surfaces of the discs, through gaps in the discs to the teeth and through the delivery passage for the ground material into the atmosphere. As shown in Fig. 1, air is drawn through an inlet 12, controlled by a valve 50, by a fan 4 on the back of the rotating disc 1. The fan blades are provided with slots 14 at their point of connection with the disc to allow air to spread over the whole surface of the back of the disc. Part of the air passes through a passage 8 to the centre of the discs and enters with the feed from hopper 9 which is prevented from entering the passage 8 by a leather &c. extension from the part 7. The air flow through the passage 8 is controlled by an adjustable flap 15 and additional air may be let in through plug 19. The remaining part of the air is driven by the fan through the outlet 13. The fixed disc 2 is water-cooled and air from a pipe 17 is inserted by nozzle 29 into a gap in the discs. The lefthand side, Fig. 3, shows a water pipe 25 and spray nozzle 24 for cooling the back of the rotating disc, the disc being provided with a flange 38 and sealing means 23, a stripper member 41 deflecting the water to the outlet 26. In a modification shown on the right-hand side of Fig. 3, air from a removable nozzle 28 is drawn in over the bearing of the rotating disc before passing to the back of the disc. The fixed disc 2 is formed with a water chamber 11 and cooling air is supplied to the teeth by jets 29, 31 from a spiral pipe 17. In Fig. 5 the stripper member comprises a rubber ring 44 on the rotary disc and a curved rubber ring 45 on the casing 5, the water being deflected from the rotary disc as shown by the arrows. The teeth on the discs, Fig. 7, are of tapered sections along their length so that in one direction of rotation a cutting action occurs with the large end A and in the other direction of rotation a crushing or bruising action takes place.

Title: Improvements in the melting and refining of glass and similar material
IPC: C03B5/225
Filed: 1936-12-24
Abstract: 482,532. Glass manufacture. NAAMLOOZE VENNOOTSCHAP MAATSCHAPPIJ TOT BEHEER EN EXPLOITATIE VAN OCTROOIEN. Dec. 24, 1936, No. 35386. Convention date, Dec. 28, 1935. [Class 56] [Also in Groups XI and XII] A method of melting and refining glass consists in melting the batch gradually by localized heat, flowing the molten material over a vertical or steeply inclined surface, and heating the flowing material to such a high temperature that it becomes very fluid and flows over the vertical surface in a thin layer from which seeds or gas bubbles can escape easily. A furnace, intended particularly for use in making glass wool, comprises a refractory container 10, Fig. 2, within which are electric resistors 14, 15, preferably made of platinum alloy, that melt and refine the glass. The resistor 14 is provided with a vent 17 and has its lower end open, and it surrounds the resistor 15 which has vertical side and end walls parallel with the adjacent walls of the resistor 14. The side walls of the resistor 15 taper downwards to form a well 18 perforated with openings 20 through which the glass may be drawn into fibres 23 by a blower 22, as described in Specification 428,720. The resistors are also provided with conducting elements 34, as described in Specification 471,838. In operation, batch 16 is melted by heat from the resistor 14, and the molten glass passes upwards between the walls of the resistors where it is raised to a high temperature and becomes very fluid. Thence it flows over the top edges of the resistor 15, or through perforations 15a formed near the top of the walls, and continues to flow in a thin layer 40 down the inner surfaces of the walls to the well 18. Owing to the fluidity of the glass and the thinness of the layer 40, gas bubbles are enabled to escape readily. In a modified construction, the refining element 15, Fig. 4, extends below the floor of the furnace. The molten glass accumulates and forms a pool 50 whence it flows over the upper edge of the element. In another modification, the pool of glass 51, Fig. 5, is supported on a platform 52 parts of which, 53, are inclined downwards to a slot 54. An electric resistor 55, which may be in the form of a flat plate, extends vertically downwards through the slot 54, and the glass flows over its surface in a thin layer to form a pool 56 of refined glass which can be discharged in any suitable way. The platform 52 may be electrically heated.

A multi-disc friction clutch 82 is arranged within the drum 86 of a band brake 88 which is lubricated by fluid passing through the clutch. The clutch is applied by an annular piston 100 in a chamber 98 formed in the drum 86, and on disengaging the clutch a valve 132 in the piston opens to prevent retention of centrifugally induced pressure behind the piston, the oil passing through the valve 132 supplementing oil from a lubricating passage 114 which passes through lubrication ports 134 to the clutch discs which are grooved to assist radial flow of the oil. The clutch discs 84 are splined to the interior of the drum 86, and the oil flows through the spline grooves to radial passages 144 leading to the inner surface of the brake band which has an annular groove 146 to facilitate distribution of the lubricant. Gearing.-A torque converter has a turbine shaft 24 forming the input of compounded planetary trains 42, 44 sharing a common sun gear 50, which is selectively stationable by the brake 88 and clutchable to the turbine shaft by the clutch 82, and having the carrier 48 of the front train 42 and the ring gear 54 of the rear train 44 connected to an output shaft 64. The ring 46 of the first train is connectible to the turbine shaft 24 by a multi-disc clutch 72, and the carrier 56 of the rear train is stationed by a one-way brake 62 and by an hydraulically applied multi-disc brake 60. Low ratio is obtained with the clutch 72 engaged and the other clutch and brakes released so that the front ring is driven and the rear carrier is stationed by the one-way brake 62. If engine braking is required brake 60 is applied. Intermediate ratio is obtained with the clutch 72 and brake 88 applied so that the front train only is operative. Direct drive is obtained by engaging clutches 72, 82 to lock the trains. Reverse is obtained by applying clutch 82 and brake 60 so that only the rear train is operative.
