Title: Improvements in and relating to filters
Inventor: CLARKE LESLIE JAMES
IPC: B01D35/20
Filed: 1962-01-26
Abstract: 956,311. Filters. WILLIAM FRANKLIN & SON Ltd. Jan. 14, 1963 [Jan. 26, 1962], No. 3171/62. Heading B1D. Solid residue is detached from a filter element by vibrations generated by a device which is actuated by a manometric device sensitive to increase in pressure difference across the filter element caused by the accretion of solid thereon. The vibration generator may act on the filter element itself, or a vibratable support for the element or on a body of liquid in which the element is immersed. The vibrations may be supersonic, sonic or of low frequency. In one embodiment, Fig. I, a conical bag filter of woven nylon 10 is immersed in container 11 provided with inlet 12 and outlet 13 for liquid to be filtered, and with sump 14 having drain outlet 15 normally closed by valve 16. Filter element 10 is secured to hollow body 17 having rigid outlet pipe 18 connected by flexible tube 19 to outlet 13. Hollow body 17 is carried by rod 21 connected to vibration generator 20. This generator comprises (Fig. 3) rigid contact arms 27, 28 mounted on blocks 29, 30, electromagnet 24 and armature 23. Electrical supply lines 25, 26 are connected to manometric device 31, Fig. 2. This comprises aneroid chambers 32, 33 separated by impervious, electricallyconducting plate 34. Chamber 32 communicates via 35 with outlet 13, and chamber 33 communicates via 36 with inlet 12. When the pressure difference in chambers 32, 33 (a function of pressure drop across the filter) is increased, contact is made between plate 34 and contacts 37, 38 causing vibrator 20 to operate. The solid detached from the element gravitates to sump 14 provided with float 40. When a predetermined level of sludge is reached, float 40 causes switch 43 to close, and energize solenoid 44, causing armature 45 to tilt beam 46 about a pivot 47 and raise valve 16. The valve closes when switch 43 opens due to the drop of the float. In a further embodiment, Fig. 5, vibrator 20 carries a rod 21a bearing a perforated plate 48 which sets up vibrations in the liquid surrounding the filter element.

Title: Improvements in or relating to the manufacture of cigarettes
IPC: A24C5/52
Filed: 1937-02-03
Abstract: 465,584. Cigarette-making machines. HOLE, F. R. Feb. 3, 1937, No. 3255. [Class 130] In a continuous-rod machine for making cigarettes provided with filter tips or mouthpieces, a continuous tobacco filler is cut into lengths which are spaced before being enclosed in a paper strip ; the tobacco filler moves at the same speed as the paper strip during the cutting operation and the spaces are formed solely by a deceleration or temporary interruption of the travel of the continuous tobacco filler. The tobacco is fed from a hopper 1 on to a belt 2 and is cut into lengths by a cutter 4 carried by a reciprocating frame 4a and passes through a tube 3 on to the paper strip 2a. The belt is looped around groups of rollers 8, 8a, 8b and 9, 9a, 9b and is driven alternately by rollers 10, 11. Each group of rollers contains a movable roller 8b, 9b, carried by a lever 12 having an arm 12a which is operated by a cam 12c. After the cutter has severed the filler the cam-actuated lever 12 lowers the roller 8b to increase the length of the loop and thus slow down or stop the run of the belt passing beneath the hopper. The space formed by the action of the rollers 8b, 9b on the belt 2 may be of greater length than the length of the filter tip or insertion and the belt 2 may then be moved slightly faster than the paper strip 2a, for a short period to close any gap between the tobacco and the insertion. In modifications (a) the belt is driven through interrupted gears whereby the whole of the belt is slowed down or stopped, and (b) a 'gripping device ensures the continued forward travel of the cut length.

Filed: 1968-04-11
Abstract: 1,222,624. Superconductor devices. MULLARD Ltd. 30 May, 1969 [11 April, 1968; 21 Jan., 1969], No. 40737/69. Divided out of 1,196,788. Addition to 1,196,788. Heading HlK. . The invention of the main Specification 1,196,788, which comprises an array of Josephson junctions constituted by a plurality of balls each separated from a superconductive part by a thin non-superconductive barrier, is modified by replacing the balls with members having one dimension very small compared with another dimension. A plate having conical or cylindrical projections on one face is placed with the projections in contact with a further plate, Fig. 1 (not shown). The projections or contacting plate may be self-oxidizable. The projections may be produced by machining, etching, or casting, or may be individually produced and soldered into holes in a plate. The projections may comprise parallel ridges produced by milling or etching grooves, Fig. 2 (not shown), and two such plates may be placed with their ridges contacting at right angles. The ridges may also be produced by securing a plurality of wires to a plate with solder or aluminium-loaded resin, Fig. 3 (not shown). The wires may be of circular or triangular cross-section. The plate contacted by the projections may have corresponding depressions and may be formed by pressing the projections into the surface of liquid mercury which is then frozen. The arrays may be operated as generators or detectors as described in the main patent. A stub aerial may comprise a large number of parallel oxide-coated wires (e.g. of Nb) embedded in solder with their ends projecting. The wires may be produced by forming projections integrally with a plate and casting solder, mercury, or lead between them, Fig. 5 (not shown). A three-dimensional array of Al or Nb wires or tubes may be assembled, Fig. 6 (not shown), and the materials may be varied within the array to broaden the bandwidth. A plurality of circular areas of superconductor material may be deposited on a quartz substrate with the edges of the areas just overlapping, Fig. 7 (not shown). Although no insulator is present between the areas it is stated that the overlapping portions form weak Josephson junctions the efficiency of which is improved by the parallel connection of further weak junctions. Alternatively a thin film having closely spaced circular apertures may be deposited on a substrate, the narrow necks of film between the apertures forming an array of weak Josephson junctions, Fig. 8 (not shown). Such a film may be deposited using an array of balls as a mask, the balls being mechanically oscillated to produce the desired pattern. A plurality of substrates may be stacked to form a three-dimensional array.
