Title: Improvements in filters
IPC: B01D25/00
Filed: 1959-07-13
Abstract: 914,523. Filters. HALLETT, S. A. Oct. 13, 1960 [July 13, 1959], No. 23919/59. Class 46. A receptacle encloses an arrangement of parallel filter elements inserted in, and protruding horizontally from, one or both sides of transversely disposed anchoring means which secure the filter elements by applying transverse pressure and which divide the receptacle, forming two chambers for unfiltered liquid which are connected so that the same liquid pressure will exist in both. In Fig. 4 an edge filter element has a central transverse drainage port; nine such elements are located with their central portions secured by screws d, Fig. 3, in columns and rows in an anchoring frame c so that the filtering portions project equally on either side (see Fig. 1). Unfiltered liquid introduced at e passes to both chambers of the outer (two-part) casing and filtrate is discharged at f. Fig. 12 shows an anchoring frame in two parts which are screwed together at g to secure between them the inner edges of bags k and the central portions h of double bag filter elements b, Fig. 13. Spacers d<SP>1</SP> are inserted between adjacent elements. Unfiltered liquid is introduced at e and filtrate is discharged at f. In a modification of this embodiment the bags are disposed with their greater area horizontal, and the lower surface, and the outer margin of the upper surface, of each bag is rendered impermeable so that cake forms only on top of the bag and is undisturbed by intermittent filtration or drainage. Subsequently a different liquid (e.g. a solvent), to dislodge or dissolve the deposited matter may be introduced. The bags may be of cloth or gauze. In another embodiment six cylinders of porous ceramic material are secured in pairs to a common central portion which may be located in the anchoring frame. The ceramic cylinders may be replaced by resin-bonded paper cartridges. In all cases, washing liquid may be introduced at the filtrate outlet.

Title: Improvements in or relating to electric discharge devices
IPC: H01J61/72
Filed: 1936-09-08
Abstract: 486,940. Discharge apparatus. WESTINGHOUSE ELECTRIC & MANUFACTURING CO. Sept. 8, 1936, No. 24432. Void. Convention date, Oct. 3, 1935. [Classes 39 (i) and 40 (v)] In order to protect the cathode of a gas or vapour-fined tube against bombardment by positive ions before reaching the operating temperature, a screen is arranged about the cathode and, when cold, blocks the passage of electrons to the anode, but allows their passage when it is sufficiently heated by radiation from the cathode. The screen may be perforated or of thin material, and is coated with electronemitting material either initially, or by material projected from the cathode. In the rectifier shown in Fig. 1, a cylindrical screen 17 of wire mesh, closed by an insulating disc 19, is interposed between the filament cathode 11 and the anode 13. The screen is maintained at a negative potential by a battery connected through a resistance. Electrons emitted from the screen due to heat radiated from the cathode, produce in the resistance a potential drop opposed to that of the biassing battery. In the lamp shown in Fig. 3, two heating elements 77, connected in series, are each surrounded by electron-emitting electrodes 83 and mesh screens 89 ; the screens and electrodes 83 are connected directly with the corresponding heating elements, the zero potential on the screens being sufficient to prevent premature starting of the discharge as long as the pressure of the mercury vapour is low. The application to tubes of the high vacuum type is suggested. In a time-delay relay Fig. 6 (not shown), the winding of the relay is connected in the anode-cathode circuit, and the bias on the screen is supplied through a set of resistances from a secondary of the transformer supplying the discharge tube.
