Title: Improvements in continuous casting
IPC: B22D11/128
Filed: 1969-04-03
Abstract: 1,271,275. Continuous casting. CONCAST A.G., and SCHLOEMANN A.G. 3 April, 1969 [19 April, 1968], No. 17717/69. Heading B3F. A continuous steel casting 6 withdrawn from a mould 3 and having a liquid core 5 passes through a guideway of consecutive cooling plates or rails, or of opposed rollers 8, 26, and in the guideway it is cooled, e.g. by the plates or rails or by sprays, at least some of the guides at one side of the casting, e.g. the rollers 26, being mounted in sections 17-24 urged towards the casting and displaceable towards and away from the casting path, the displacement away from the path, at least of the first section 17, being limited by abutment means 44 to an amount 46, Fig. 2 (possibly different for different groups of rollers), to restrict bulging of the casting to a degree which avoids cracks and breakthrough. The guideway may be vertical instead of curved. The rollers 8 are grouped in fixed sections 9-14. Beyond a withdrawing-straightening unit 7, supporting rollers, like the rollers 8, are mounted in fixed bearings and there may be further cooling. The roller sections are urged towards the casting surface by the weight of the sections or by hydraulic pressure or springs in a chamber 47 between a fixed piston 58 and a portion of the section, e.g. 17, forming a cylinder mounted on the piston. The rollers are thus capable of engaging a dummy bar 54, Fig. 2, of smaller size than the casting. The admission of fluid to a chamber 41 at the other end of the piston displaces the section away from the casting surface. The stop 44 is selected according to casting thickness and acts by contacting the face 59 of the piston 58. In an alternative construction, the weight of the sections is counteracted by springs (48) or fluid pressure in the chamber 41 and the stop 44 is replaced by a screwed stop (50) adjustable according to casting thickness. In an alternative arrangement, the pistons 58 are attached to the roller sections, the cylinders being fixed. The sections may be displaceable on rods outside the cylinders.

Title: Improvements relating to the separation of liquids from solids by means of presses
IPC: B30B9/04
Filed: 1935-06-28
Abstract: 449,940. Presses for separating liquids from solids. CARVER, F. S., 345, Hudson Street, New York, U.S.A. June 28, 1935, No. 18520. [Class 46] A press for separating liquids such as oil and water from substances such as cocoa, copra and sewage which have been reduced to a sufficiently fluid state for pumping comprises at least three coaxial press chambers which can be shortened and to which the fluid can be supplied individually through pipes leading to the centres of the chambers. In the construction shown, a number of chambers are formed by movable platens 22 and rings 72 the fluid to be treated entering the chambers through radial passages 22a. To one side of each platen is secured a piston 34 and to the opposite side a filter plate 36<1>, the piston 34 also carrying a filter plate 36. The filter plates are recessed and provided with filtering elements 38 consisting of filter cloth, perforated metal sheet and coarse wire mesh. In the faces of the plates 36, 36<1> next to the filtering elements are circular slots 48 leading by passages passing through the plates to radial slots 52 through which the expressed liquid is conducted to slots 54 in the pistons 34 and slots 55 in the rings 72. In the centre of each piston 34 and its filtering element 38 is a hollow plug 64 the bore of which communicates through a central passage 22b in the piston with the radial passage 22a in the corresponding platen 22. The plug 64 is fitted with a check valve 69. The passages 22<a> are connected externally of the press to separate flexible tubes 71 which are all joined to a common pipe line 70 through which the fluid to be treated is pumped. The rings 72 are slidable over the pistons and filter plates and are pressed away from the platens on one side by springs 88. In this position the rings overlap both filter plates 36, 361 and close the chambers between them. The chambers are opened to allow the press cakes to fall out by retracting the rings over the pistons. After the chambers have been filled with fluid they are shortened by a hydraulic ram 104, the expressed liquids escaping through the slots 54, 55 and being received in a pan 120 having a spout loading to a tank. When the pressing is complete the pressure is released causing the springs 88 to separate the platens 22. The rings 72 are then retracted over the pistons thus opening the chambers and causing the cakes to drop out. The movement of the rings is produced through mechanism operated by a hydraulic ram 150 connected to a yoke 156 carrying rods 130 which engage the rings.
