Title: Improvements in and relating to the aeration treatment of sewage
IPC: C02F3/12
Filed: 1948-07-26
Abstract: 651,167. Treatment of sewage. ACTIVATED SLUDGE, Ltd., and HEDGE, W. July 26, 1948, No. 19947. [Class 111] In a sewage treatment plant comprising a trough almost wholly surrounding a sedimentation tank, incoming sewage being fed to the trough to which air can also be introduced for aerating the sewage and the trough constituting an aeration zone from which sewage and sludge are delivered to the sedimentation tank and to a reaction zone fed with a proportion of settled sludge from the sedimentation tank, the direction of flow of the sewage through the trough is reversible as desired so that biological growths in the aeration zone can thereby be reduced. As shown, a proportion of settled sludge is delivered from the sedimentation tank 2 alternatively as desired by either of pipes 11 to either end of the trough 4 for flow through the reactivation zone thereof indicated by broken arrows A and sewage is admitted to the trough at a correspondingly alternative point, e.g. 32 at the end of the reactivation zone, sewage and sludge being withdrawn from the trough at a correspondingly alternative point as by pipes 18 at the end of the aeration zone indicated by continuous arrows B for delivery to the sedimentation tank through chamber 19 and pipe 20. A movable or flexible conduit 30 or pipe of variable length is used to introduce the sewage from the incoming feed pipes 27, 28 into the trough at any selected point 32 which determines the periphery of the aeration zone. Alternatively the sewage may be introduced by a peripheral launder or piping surrounding the trough and having controlled weirs or outlets at a plurality of points the selection of which determines the direction of flow through the aeration zone. As shown in Fig. 5, such sewage supply launder 49 has an inlet 59 from the launder to the aeration trough 60 diametrically opposite the sewage supply point 50 with associated gates 66 or stop plate positions on both sides of the inlet 59 and has one or more auxiliary inlets 62, 63, 64, 67, 68, 69 on each side of the diameter of the trough between the inlet 59 and supply point 50 whereby the length of the reactivation section and aeration zone can be varied to suit the load on the plant. The inlet 59 and auxiliary inlets are disposed at progressively different levels so that they automatically admit sewage at different positions in accordance with the load or rate of sewage flow to the plant. The inlets such as 64, 69 intended to operate with larger flows are larger in cross-section than the inlets which operate with smaller flows. The aeration trough is provided with screens 58.

Abstract: 742,333. Aerials. BREVETS AERO-MECANIQUES SOC. ANON. May 31, 1954 [July 22, 1953], No. 20347/53. Class 40 (7). [Also in Groups XI, XX and XXI] Pedals 13, Figs. 3, 4, mounted on a turntable 7 rotatable on a central pivot 3 on a base 1, under the thrust and control of the operator's feet effect the training of a radar aerial mounted on the turntable. According to the invention the base 1 has a fixed circular track 29 coaxial with the training pivot 3 and journalled on the pivot 3 is a pair of arms 19 extending radially in opposite directions to the track 29, each arm being loaded by a spring 22 to a given angular position relative to the turntable and each arm having a shoe 28 to engage against the track 29 to provide a fixed point from which the turntable can be turned under thrust transmitted through connecting means from one of the pedals 13 respectively. The transmission of pedal pressure to the shoe 28 may be hydraulic but, as shown, it comprises a cam lever 17 pivoted in the arm 19 to bear on the shoe and a connecting-rod 16 universally jointed to the cam lever 17 and pedal 13. The shoe 28 is urged by a spring 31 away from the track 29. Two helical torsion springs 22 are coiled around a spacer ring 21 on the pivot 3, one for each arm 19, the ends of each spring crossing one another and anchoring circumferentially in opposite directions against axial pins 23, 24 on the turntable 7 and arm 19 respectively. The spring 22 thus tends to maintain the arm 19 in a given position relative to the turntable 7 in which the pins 23, 24 are radially aligned and also acts on the pedal 13 tending to maintain it in the vertical position, in which position the shoe 28 is clear of the track 29. Initial thrust on the pedal applies the shoe 28 against the track 29 fixing the arm 19 relatively to the base 1 and continued thrust on the pedal turns the whole training structure until the pedal meets an abutment 15, Fig. 2 (not shown). On release of the pedal, the shoe 28 is spring-urged from the track 29 and allows the arm 19 to follow up the training structure under the increased torsion of the spring 22 and the pedal is returned to vertical position. A further thrust can then be applied. The opposed faces of the shoes 28 and track 29 may be simple friction surfaces or their interengagement made more positive by the provision of serrations.

Abstract: For use in a digital encoder a disc or the internal surface of a glass drum as described in Specification 1,109,461, is coated by vapour deposition with Al, Cu or Ag using two masks in succession. A drum 26, Fig. 5 (not shown) is coated by placing within it a cylindrical mask 25 supported on a steel dumbell 11 within which an electrode carrier 27 is rotatably mounted.  Three cartridge type removable, shielded vapour sources 33 are placed equidistantly around the carrier 27 which is reciprocated through 120 DEG  by a shaft 40. The drum is cleaned by glow discharge, coated through the first mask which is then replaced by the second mask and the coating completed through this.  The cylindrical mask is made, Fig. 3 (not shown), by sputtering Ni on to a tubular copper substrate 12 mounted on a steel dumbell 11 through focusing slits 21, 23 and through a slotted steel plate 15 which moves across the sputter electrode 19 whilst the substrate 12 rotates.  Further areas of the mask are deposited by rotating the substrate past stationary slots and when the mask is completed the copper is dissolved away.  The plate 15 can be formed into a cylinder around which two substrates and two sputtering electrodes are rotated close to the cylinder.  Similar methods may be used for coating discs and forming disc shaped masks.

Filed: 1950-08-21
Abstract: A bearing element, (see Group XXXIV), has a matrix or body of any suitable material in which at least the bearing surface or bearing surface layer consists of, or comprises, boron nitride (BN).  The BN which is an effective solid lubricant may be compacted into a porous sintered metal matrix or metallic wool body or into a plastic sponge structure.  The BN may be incorporated in the matrix in the form of powder, with or without a binder, or in suspension, e.g. alcohol as described in Specification 707,065, [Group XXXIV].  If a binder such as corn syrup or fish glue is used the BN must be baked at 150-200 DEG C. The BN may, however, be produced in situ by gaseous or other chemical treatment of boron incorporated in the matrix or forming the bearing surface or layer, and in a further modification the BN may be mixed with metallic powder such as 89/11 Cu-Sn and the whole sintered and compacted, the proportion of BN being 5-30 per cent.  In yet a further modification, the BN may be mixed with a synthetic plastic powder and pressed to form the bearing element.ALSO:A plain bearing or liner &c. has its bearing surface or surface layer consisting of or comprising boron nitride.  Where the bearing is required to conduct heat the supporting matrix is metallic and may consist of a porous structure produced as described in Specification 701,690, [Group XXXIV], by sintering metallic powders, the boron nitride being applied to or formed in the structure afterwards.  Alternatively, the matrix is formed with surface pits which are filled with boron nitride.  The bearing may however consist of a layer of metallic wool compacted with boron nitride.  The boron nitride may be applied or incorporated in the form of a powder, with or without a binder, or in an alcohol suspension as described in Specification 707,065, [Group XXXIV], or may be produced in situ in the matrix or by gaseous or chemical treatment of boron previously incorporated in the matrix. In all the above embodiments, as the bearing wears the surface remains a composite structure, in part nitride and in part matrix smeared with nitride.  In a further modification a porous matrix in a layer 0.005 inches thick is produced on a steel backing 0.050 inches thick, boron nitride being compacted into the pores.  In yet a further modification 5-30 per cent. boron nitride is mixed with 89/11 copper/tin powder and is sintered and compacted, or boron nitride mixed with a binder such as corn syrup or fish glue may be applied to a surface and then baked at 150-200 DEG C.  The matrix may however consist of a combination of metallic and non-metallic materials. Composite strip material for use in the production of liners &c. comprises a metallic matrix having boron nitride incorporated in at least the bearing surface or bearing surface layer.
