Title: Improvements in Method of and Apparatus for Treating House Waste and Sewage.
Inventor: MEGILL EDWARD LANDON
IPC: B01D21/00
Filed: 1917-04-18
Abstract: 111,422. Megill, E. L. April 18, 1917. Plant.-A plant for treating water - carried domestic sewage, to replace the cesspool or septic tank, treatment comprises an outer tank and an inner receptacle, the intervening space being filled with sand or like filtering material. Sewage is fed to the inner receptacle, where solid matters settle. The liquid passes through openings in the base and percolates through the sand. The apparatus is ventilated to cause a stream of air to pass over the materials. A number of tanks may be arranged in series to deal with excessive flows of sewage, and a number of series may be used to rest and clean any one of them. Sewage from a pipe 21, Fig. 2, passes through a distributing device consisting of a ball-jointed pipe 25, Fig. 5, adapted to be moved by a handle 28 so as to discharge into one of a number of pipes 22 supplying series of tanks. Each series is formed by a shallow concrete trough 1 divided by transverse concrete walls 3 which extend not quite to the side walls. Removable side boards 4 slide in grooves in the walls 3 to form inner compartments 2, 2<a>, 2<b>, openings 12 being left at the base. The spaces between the side-boards and the walls are filled with sand and contain reciprocatable rakes 10, Fig. 3, which project into the openings 12. The trough is enclosed by removable covers 17 with inspection windows 50 which may be large so that the light may act upon the sewage, and by an insect-excluding screen 19. Air is drawn through by a ventilating pipe 34. In operation. sewage fed into the receptacle 2 deposits the solid matters therein, and the liquid percolates through the sand in the space outside the sideboards 4 and through sand on the open end 18 of the trough. When excessive flow occurs, sewage passes into the succeeding receptacles 2<a>, 2<b> through pipes 8 bent downwardly at the inlet ends to prevent passage of grease and floating solids. Circular tanks may be used and may be divided by a partition so that one part may be used while the other part is resting or being cleaned.

Title: Improvements in or relating to the preparation of asphaltic bitumen compositions
IPC: C08L95/00
Filed: 1946-02-21
Abstract: Asphaltic bitumen compositions are prepared by grinding together asphaltic bitumens, preferably in lump form, with melting points above about 100 DEG C.  (Ring & Ball) and penetrations at 25 DEG C. lower than about 25 and more than 50 per cent by weight (on total mixture) of mineral fillers to a powder preferably having a size of grain less than 1 mm.  Artificial bitumens from mineral oil or natural asphaltic bitumens or asphaltic bitumens of the blown type may be used.  Suitable fillers are quartz powder, limestone powder, shale powder, flue-ash, rock dust, ground microasbestos, asbestos powder, ground mica and talcum powder.  The composition may be used for coating iron pipes (see Group XXVIII) or mixed with solvents, e.g. benzene, to form a spreadable mass suitable for painting a heat resisting or acid proof layer for tanks.

Title: Improvements in or relating to recording devices for use in seismic prospecting
Inventor: DIJCK WILLEM JOHANNES DOMINICU
IPC: G01V1/24
Filed: 1954-02-26
Abstract: 758,483. Recording-apparatus. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Feb. 25, 1955 [Feb. 26, 1954], No. 5743/54. Class 106 (4). Recording-apparatus comprises one or more bits or styli 1-12, which are each caused to move under the control of the signal output from an associated seismic detector so as to trace on a relatively moving film 34 an optically observable track whose width varies with the signal output, As shown in Fig. 1, a wedgeshaped bit is attached to an armature 13 rotatable about an axis 14 between the poles of a permanent magnet 16. On passing a signal current from a seismic detector through a winding 15 the bit 1 penetrates an opaque film to a depth proportional to the signal thus cutting a transparent track of proportional width. In the embodiment of Fig. 3, the bit 1 is carried for parallel motion by arms 32, 21 clamped at 31 and the arm 21 carries a body 41 of magnetic material in the air gap 51 of a toroidal magnetic yoke 61 on which is wound uniformly a winding 71 through which is passed both a constant direct current and a signal current from a detector. The constant current is adjusted so that in the absence of signal current the body 41 is drawn against the spring tension of the arm 21 or of an auxiliary spring so to position the bit that a track is drawn of about half the maximum width. The film may be mounted on a celluloid tape or on a glass plate, e.g. 6 by 9 centimetres in size, and is preferably moved between 2 to 5 centimetres a second. The bits may be actuated in accordance with the signals electrostatically using an elastic dielectric body or a piezo-electric crystal. The marking action may be by melting with a heated bit, by chemical reaction or by electric discharge and the track may be made opaque on a transparent film. Quick starting necessitates a strong motor or a clutch or, with a revolving film, means for moving the bits into and out of contact with the film when a record is required. The seismogram may be assessed immediately by projection or under a low-power microscope and is suitable for optical frequency analysis.

Title: A method of cooling small lumpy material on air-permeable conveyor means
IPC: F27D15/02
Filed: 1962-02-15
Abstract: 924,346. Cooling furnace charges. POLYSIUS G.m.b.H. Feb. 15, 1962 [March 9, 1961], No. 5923/62. Class 51 (2). In a method of cooling small lumpy material such as cement clinker or burnt limestone in the form of a bed on an air permeable travelling grate cooler by air which is subsequently used wholly as combustion air in a preceding furnacing or kilning plant, a proportion of the total volume of cooling air is passed in crossflow once through the bed of material in a section of the travelling grate immediately adjacent its entry end whilst the remainder of the air is passed in cross-flow two or more times through the bed of material in a following section of grate, beginning at the discharge end of the travelling grate and then consecutively passing through progressively hotter sections of material. The Figure shows how the method may be applied to rotary cement kiln. Material leaving the rotary kiln 1 enters a pre-cooling zone 2 of an air-permeable travelling grate cooler upon which it is then conveyed through the chamber 3 and 4 constituting an after-cooling zone to be discharged from the grate at 5. Below the pre-cooling zone 2 is situated an air chamber 6 into which a fan 7 forces between 20 and 40% of the total cooling air at a high pressure of about 200-300 mm. water column the air escaping through the grate and the bed of material thereon at such velocity as to fluidize the material to the zone 2 lowering the temperature of the material falling on to the said grate to such a degree that it ceases to cake and aggregate in the bed. A fan 10 blows fresh air at a low pressure, say 50 mm. water column into an air chamber 9 situated below the chamber 4 into which air flows through the bed of material on the travelling grate. The low-pressure air is extracted from the chamber 4 by a fan 12 through a duct 11 and is fed to a chamber 8 from which it passes through the bed for a second time, this time passing into the chamber 3 from whence after mixing with the high-pressure air from the fan 7 it passes to the kiln 1.

Filed: 1956-02-24
Abstract: 826,742. Preventing and extinguishing fires. DARIC, G. Feb. 24, 1956, No. 5926/56. Class 47 [Also in Group XXIX] The fire hazard associated with a liquid hydrocarbon storage tank is reduced by pumping water from an annular space formed round the tank base by a wall 10 to a spray 15 by a pump 16, and hence cooling the tank walls when the vapour pressure inside the tank exceeds a predetermined value. The annular space may also contain a layer of spilt hydrocarbon and hence density-sensing means may be provided to prevent it being delivered to spray 15. The pump 16 can also be used to deliver water to a foam-generating unit for fire-extinguishing, by closing valve 24 and opening valve 25, either manually or automatically in response to temperaturesensing means.
