Title: Improvements in or relating to straining or filtering apparatus
IPC: B01D25/00
Filed: 1923-02-03
Abstract: 215,098. Fulcher, F. C. Feb. 3, 1923. Impurities, separating from gases.-A straining element for liquids or gases comprises a plurality of thin discs spaced apart on a carrier, either by washers or by pressed-up portions of the discs, so as to form peripheral straining slots at their edges. Holes in the discs combine to form inlet or outlet conduits. Scraper blades are provided which permanently engage the slots, the discs and blades being relatively movable. Apparatus comprising four such elements arranged in pairs endwise, the two pairs being parallel, is shown in Figs. 1 and 2. The discs 17 are mounted on a rotatable shaft 12, and have holes 19 which form the internal passages, and other holes through which are passed carrier rods 21. The discs are spaced apart by washers on the rods 21. The scraper blades 28 are carried by rods 26, the operative edges of the blades being oblique to the peripheries of the discs. These parts are all carried by members 8, 9 which close openings in opposite ends of the casing 1, the arrangement being such that the strainer parts can be removed as a whole with one of these members. Discs 30, which embrace the rods 26 and rods 32 fixed to the casing, serve as guides and supports. A spring 25 presses each element towards the corresponding ends of the casing. The fluid enters the casing through an inlet 2, is directed to the space between the two pairs of strainers by a wall 4 and is strained as it passes through the slots. The purified fluid is discharged through the internal passages of the elements, grooves 10 in the members 8, 9, a duct 11 in the casing, and an outlet 3. A modification is described in which the strainer casing is divided into three compartments, each of which contains one straining element. The fluid passes from the interior of one element to the space outside the next and is thus subjected to straining in each compartment. The elements may have successively finer slots. Fig. 6 shows a small strainer arranged vertically. The discs 17 are spaced apart by washers on the shaft 12, which, like the rods 26 which carry the scraper blades, are supported from the cover 46 of the casing. The scrapers are constituted by inward radial projections from rings 45. The blades may, alternatively, be carried by radial projections from rings on the shaft 12. The scraper blades may be constituted by wires extending across the casing, and may take the form of flattened loops. Specification 145,339, [Class 46, Filtering &c.], is referred to.

IPC: G01D5/20
Filed: 1959-01-30
Abstract: 882,123. Electric selective signalling systems. GENERAL ELECTRIC CO. Ltd. Jan. 18, 1960 [Jan. 30, 1959], No. 3517/59. Class 40 (1). In an electric shaft digitizer as described in Specification 863,027 which is referred to, sixbit accuracy is obtained from a mechanism which previously only produced five-bits (the mechanism having only 32 pole pieces) by providing the mechanism with an additional units bit winding arranged to be 90 degrees out of phase with the original units bit winding and combining these two bits to produce a sixth bit. As shown in Fig. 4 the first five bits are produced by coils 9 to 13 which give a pattern of in-phase or out-of-phase outputs. The output from coil 9, the units bit, is also combined with that from an additional units bit coil 28 by summing resistors 38, 42, the currents through which are shown in Fig. 6 (a) and (b) where the intervals P0, P1 &c. correspond to the successive digital ranges as demarcated by the pole pieces, and where a monophylic code is being employed so that both units bits make a complete cycle every two pole piece intervals. These two currents are summed, as shown at (c), to give, after shaping, the desired output (d) which functions as a sixth bit.
