Filed: 1974-03-08
Abstract: 1468377 Etching USS ENGS & CONSULTANTS Inc 8 March 1974 [8 March 1973] 10546/74 Heading B6J An internal taper is formed in the walls of a sleeve-like body S, Figs. 1 and 2, by exposing them to an etching solution which forms a pool P within the body, the level of the pool surface being gradually changed. The pool is formed by pumping etchant from a tank 12 through pipes 16, 19, and bores 30, 31 in a plate 32, up into the sleeve S, which is secured to the plate. The etchant returns to the tank by overflow into a telescopable member 44, and the level of the pool is determined by the level of the top of the member 44. The member 44 is raised and extended by a wire 51 attached to a winch mechanism comprising a motor driving a spindle formed with a helical groove in which the wire runs, and the diameter of the spindle varies from one end to the other in such a way as to control the height of the pool to take account of variation in temperature and strength of the etchant and produce a uniform taper.

Key and groove 7a, 8a connect member 7 to bevel gears 8, 12 by which core 13 is rotated to wind the motor 14. A braking spring 11 engaging a bush 9 to which spring 6 is attached and rotatable relative to member 7 provides the resistance to rotation which tightens spring 6. Gearing on the shaft of core 13 drives film transport, shutter tensioning, and other mechanisms.

Class 64(1) A sealing arrangement for a rotarymatrix type regenerative heat-exchanger comprises an annular chamber formed by cylindrical and radial walls of the stationary casing structure and the end wall of the rotor, sealing rings n, o being simultaneously pressed against two opposed walls of the casing and the end wall of the rotor by springs r pressing indirectly on the rings and either directly or indirectly upon the walls of the casing. The invention is applicable to apparatus incorporating either drum type rotors as shown and also as described in Specification 655,313, or disc type rotors. In the apparatus shown having a drum type rotor, the annular chamber i is formed by walls j, k, l of the casing and end wall m of the rotor, the springs r being located respectively between a sleeve s<SP>1</SP> and the inner race s of the rotor bearing t and other rings p, q bearing on the sealing rings n, o. The annular chamber i may be placed in communication with a low temperature, high pressure air space of the regenerator, e.g. by means of a pipe u, and the consequent flow of high pressure air through the space i cools the bearing and assists in applying a sealing pressure, thereby relieving the springs r of some of their loading.

Abstract: 881,026. Tanks. CONCH INTERNATIONAL METHANE Ltd. April 1, 1959, No. 11058/59. Class 69 (1). In a method of applying panels 7, 9, Fig. 1, of balsa wood &c., attached by adhesive to the interior of a large tank 1 for carrying methane &c., the panels compressed edgewise while the adhesive is setting so that the lining is precompressed to compensate for shrinkage which would otherwise produce gaps at the joints. In lining a large tank the floor 2 or roof is lined with annular segments 5, 7 which are laid in stages alternately with the panels 8, 9 on the walls so that a stepped joint is obtained in the region of a filler ring 6 at the welded comers. Apparatus for applying the wall panels 9 comprises a central support pivot 10, Fig. 2, having a vertically adjustable and rotatable slider 11 carrying radial arms 15 which may be swung to any position opposite a panel 9 to be applied. The arms 15 carry a segmental pressure plate 18 which is brought into position by radially disposed hydraulic rams 23. The plate 18 carries a pneumatic pressure pad engaging the work and forms part of a segmental support ring 16 similarly carried by sliders 19, Fig. 8, on radial arms 14 and actuated by hydraulic rams 22. The ring segments 16, 18 are interlocked by ring expanding rams 17 which are actuated to apply full pressure to the ring segments 16, 18 when required, the hydraulic rams 22, 23 merely being used to bring the segments into or out of position. One end of the segmented ring 16 carries a plurality of hydraulic presses 25 adapted to engage the end edge of the panel 9 to apply the tangential pressure. The pressure on the top edge of the panel is applied by a segmental anvil 32, Fig. 6, carried by pneumatic suction pad member 26 attached to the tank wall above the ring section 18. The member 26 has sponge rubber beads 28, Fig. 5, in sealing engagement with the tank wall and carries the anvil 32 on pivoted arms 30, 30a which are separated by a pneumatic pad 31 to apply downward pressure on the edge of the panel 9. An attachment for applying the top and bottom panels 69, 70, Fig. 9, comprises a vertically disposed framework 54 having projections 60 slidable along radial arms 58, 59 to the required position and being extendable at 66 to bring pneumatic pads 63 or 64 into operative position. Edgewise pressure is applied in two directions by pneumatic suction pads 71, 72 which are similar to the pads 26.

Title: Improvements in and relating to elements for use in filters and the like
IPC: B01D29/00
Filed: 1932-04-20
Abstract: 388,247. Filters. DURANT, H. T., The Lodge, Worth Park, Crawley, Sussex, and STUBBINGS, E. O., 9, Salisbury Road, Carshalton, Surrey. April 20, 1932, Nos. 11365 and 30860. [Class 46.] A filter cloth or other medium is mounted on a resilient support which yields when a difference of pressure is set up between its sides but is capable of elastic recovery when the pressure is released. Figs. 2 and 3 show a filter element comprising cloth or canvas 23, a layer of jute sacking 22, a cylinder 21 of porous rubber, another layer 20 of jute and an inner core built up of four segments 11 of wood, ebonite or iron spaced apart by wedges 14 and formed with circumferential and longitudinal channels on the outer surface. A suction pipe 4 passes through the centre of the element. In a modified form of element shown in Fig. 5, the rubber cylinder and one layer of jute are omitted and resiliency is secured by using strips 28 of rubber to separate the segments 11. Pneumatic cushions may be used in place of the rubber cylinder 21 or of the rubber strips 28. Fig. 1 shows thickening apparatus with elements 3 as described and a central rotary shaft 6 carrying an agitating paddle 5 and horizontal cutter blades 8, 9, which loosen the settled material and promote its discharge through an outlet 7. The cake is detached from a filter element by breaking the suction and causing liquid to percolate or ooze through the element in the reverse direction. This may be done without stopping the suction pump by connecting the suction side of the pump to a supply of liquid in excess of that which the pump can take. It is stated that filter cloth having a backing of perforated sheet rubber may be used for the elements and that one or more spiral or other springs may be arranged under the filter cloth so as to allow of deformation during filtering and elastic recovery when the filtering pressure is released.
