Title: Processing activated sludge
IPC: C02F11/13
Filed: 1970-07-23
Abstract: 1325072 Biological purification NETHERLANDS ORGANISATION FOR APPLIED SCIENTIFIC RESEARCH ON BEHALF OF PUBLIC HEALTH 23 July 1970 [23 July 1969] 35761/70 Heading C1C Sludge from a biological purification process is brought to a pH of 10 to 13 by the addition of alkali and is then hydrolysed at 90-180 C. until at least 75% of the organic matter is dissolved. The insoluble residue is then removed and the liquid is recycled into the purification process. The alkali is preferably caustic soda and the hydrolysis may be accelerated by various sulphur compounds or lithium ions and may be carried out under pressure. Sewage is fed to a sedimentation tank 2, Fig. 1, from which sludge is passed to a digester 6 and the liquid waste to an aeration tank 4 and then to a sedimentation tank 8, from which purified liquid is taken at 13. Part of the sludge from the tank 8 is fed back to the aeration tank 4 (or to digester 6) and part is fed, together with sludge from digester 6, via a heat-exchanger 11 to a reactor 12 to which the alkali is added at 14 and in which the hydrolysis takes place. The mixture is then separated in separator 15 into the insoluble residue which is removed at 16 and liquid 17 which is fed back through the heat-exchanger 11 either to the digester 6 or to the aeration tank 4. In an oxidation ditch process, Fig. 2, sewage is fed at 31 to the ditch 32 which is provided with an aerator 33, and sludge is removed at 35, concentrated at 36 and mixed at 38 with the alkali. The sludge is then pumped by high-pressure pump 42 through a screen 41 and heat-exchanger 43 to reactor 45 for hydrolysis, and the mixture is then passed through the heat-exchanger to a tank 47 where it is diluted with pure effluent from the ditch. In a separator 49, the mixture is then separated into insoluble residue, which may be dried at 52, and liquid which is fed back to the ditch.

Patent GB-821595-A (GB)
Title: Improvements relating to mobile pick-up balers
IPC: A01F15/10
Filed: 1957-11-18
Abstract: 821,595. Baling-machines. WELGER, O., WELGER, K., and NESTLER, H. [trading as WELGER GEB.]. Nov. 18, 1957 [Jan. 12, 1957], No. 35797/57. Class 94(1). [Also in Group XXX] A baling-machine incorporates a rotary "pick-up" device fitted with groups of fingers which lift the crop to be baled from the ground, at least one group also serving to feed the crop through an inlet opening into a chamber in which it is compressed by a plunger. In one form, Figs. 1 and 2, the compressing-plunger 5 is mounted on a shaft 7 for rocking movement in an arcuate baling chamber 1 having an inlet opening 38, and is operated through crank arms 11 and 13 and connecting rods 8 by a shaft 12 driven through gearing by a shaft 23 coupled to a power take-off on the tractor. The shaft 12 carries end discs 33 and 34 formed with bearings for four tubular shafts 30 carrying groups of spring fingers 26, 27, 28 and 29 respectively, each shaft being fitted with a control arm 35 carrying a roller 36 engaging a cam slot 37. The shaft 12 also carries a group of rigid fingers or plates 41. The plunger 5 is formed by a series of plates 5<SP>111</SP> secured to a shaft 42 and spaced apart so that the fingers 41 can pass between them. The opening 38 forms the exit from a collecting chamber 39 defined between a resilient wall 40<SP>1</SP> and a wall 40 which is formed with slots 40<SP>11</SP> to allow passage of the fingers 26-29 and 41. The fingers 26-29 normally extend radially and in this position operate to pick up the crop from the ground and lift it into the chamber 39 where is accumulates against the side 5<SP>1</SP> of the plunger 5 while the latter is compressing the preceding bale. The shape of the cam slot 37 is such that as each group approaches the wall 40 the fingers are retracted to a tangential position and pass under the wall. The fingers 41 also serve to pick-up the crop, but their primary function is to sweep the accumulated material from the chamber 39 through the opening 38 into the chamber 1 above the plunger 5 which is then in the retracted position. In a modification, Figs. .3 and 4 (not shown), fingers 43, corresponding to the fingers 41, are carried by an eccentric shaft mounted in the end discs 33, 34 and their position is controlled by a second cam slot at the other end of the shaft 12 so that they are retracted and pass under the wall 40 after feeding the crop into the chamber. The fingers 41 may be resiliently mounted on the shaft 12, or consist of two relatively movable parts interconnected by a spring, so that they may yield if an obstruction is encountered, see Figs. 5 and 7 (not shown). Alternatively, the fingers 41 may be shorter than the fingers 26-29 so that they do not come into contact with obstructions on the ground, see Fig. 6 (not shown).

Title: Method for heat curing hollow spherical objects
IPC: B29B15/00
Filed: 1974-08-14
Abstract: 1452011 Curing hollow balls GENERAL TIRE & RUBBER CO 14 Aug 1974 [11 Oct 1973] 35812/74 Heading B5A [Also in Division A6] The adhesive securing the covers of tennis balls is heat cured in a continuous process whereby each ball is successively introduced through an air lock (60, Figs. 1 and 6, not shown) into a confining mould 28 housed within a curing environment 10 that is maintained at selected curing temperature and pressure, the ball then passing through the mould 28 for a selected cure time after which it passes into a cooling environment 72 maintained at a selected temperature, and from which it is removed by means of a discharge air lock (74, Figs. 1 and 4, not shown). The moulding apparatus is in the form of a spiral groove 30 in the mould plate 28, the cross-section being semicircular and of radius substantially the same as that of the balls. A plate 32 is rotated beneath the fixed plate 28 to move the balls along the groove 30 from the inlet 54 to the outlet at the rim the length of spiral 30 and speed of rotation providing the desired cure time. Separation of the plates 28 and 32 is adjustable by means of four units 38 attached to plate 32. Steam or electrical heating coils 78 and 80 provide the curing temperature, air pumped through inlet 76 the desired pressure. The cooling environment is in the form of tubing 72 surrounded for part or all of its length by water-carrying piping 82. The air locks (60, Figs. 1 and 6, not shown and 74, Figs. 1 and 4, not shown) may both be in the form of ball plug valves that have been modified for limited 180 degree rotation between positions where their central cavities are connected (a) to the interior of the apparatus or (b) to the exterior. The valves may be linked for corresponding action. Valve (60, Figs. 1 and 6, not shown) may be cycled on a time basis or as a function of the rotation of the plate. Smooth non- adhering surfaces are desirable for the plate 32 and groove 30 to prevent adhesion of the balls thereto; this may be achieved by metal plating or coating with fluorocarbon resin. An air lock may be provided between the curing chamber 10 and the cooling environment 72 so that different pressures may be maintained in the two regions.

Abstract: 801,227. Measuring ozone concentration photo-electrically. BRITISH OXYGEN CO., Ltd. Dec. 5, 1956 [Dec. 20,1955], No. 36525/55. Class 40 (3). The concentration of ozone when mixed with colourless gas is measured by passing light through it, filtering wavelengths 5400 to 6400Š on to a photovoltaic cell and measuring the difference between its output and that of the cell subjected to light from a source which fluctuates with the other source. Light from a source 11 is passed through the glass tubes 14, 17 (the outside walls of which are silvered) filters 18, 19 and on to the cells 12, 13. These cells are connected in opposition to a galvanometer which has a variable resistance across it so that its sensitivity may be controlled. In operation, the tube 14 is filled with a colourless gas and the galvanometer needle set to zero by operation of the attenuator 20. The ozone is then introduced into the tube 14 and the deflection of the galvanometer is an indication of its concentration.

Title: Memory
IPC: G11C11/06
Filed: 1963-09-17
Abstract: 1,023,359. Magnetic storage apparatus. RADIO CORPORATION OF AMERICA. Sept. 17, 1963 [Oct. 4, 1962], No. 36630/63. Heading H3B. The orthogonal row and column windings of a magnetic memory are embedded in different planes in an integral sheet of ferrite material. Construction. The row and column windings are printed as single conductors on respective sheets of doctor bladed green ferrite. These sheets, together with a thin unprinted sheet, are assembled into a sandwich by heat and pressure. Subsequently the sandwich is fired to sinter the material and to form a homogeneous magnetic ferrite sheet in which the windings are embedded, Fig. 2 (not shown). Two-core-per-bit store. As shown in Fig. 1, the spaced row and column windings comprise word conductors 12-14 and digit-sense conductors 16-19, the conductors 16, 18 being connected to " 1 " digit drivers 24, 32 and to one side of respective differential sense amplifiers 30, 34, while the conductors 17, 19 are connected to " 0 " digit drivers 25, 33 and to the other side of the respective sense amplifiers. Each pair of conductors 16, 17 and 18, 19 in association with the word conductors 12-14 define a respective column of two-core-per-bit storage locations. A word stored in any row is read out by applying a strong pulse Ir to a word conductor such as 12 from a word driver 20-22 to establish a tubular remanent field 40, Fig. 3, about that conductor. To write a word a " 1 " or " 0 " digit driver in each column of storage locations applies a pulse Id to the associated digit-sense conductors 16-19. At the same time the word conductor selected is pulsed by a current Iw of opposite polarity to Ir. Relative values of these currents may be Id = Ir/10 to Ir/20 and Iw = 3Ir/4. At the cross points where both digit and word currents Id, Iw are present, Fig. 5, a diagonal remanent field 50 of opposite direction to field 40 is established. At other cross points the single current Id is without effect. Consequently at each storage location such as the intersections of conductors 12, 16 and 17 only one cross point will have a diagonal field established depending on which digit driver 24 or 25 is pulsed. The flux conditions in Fig. 3 are re-established by a further read pulse, and an output pulse is induced in one of the digit/sense conductors of each pair 16, 17 and 18, 19 which is identified by the associated differential amplifier. One-core-per-bit store. The arrangement may be modified by using the polarity of the Id pulses in the digit-sense conductors to identify the digit to be stored. In this case either a diagonal flux SO or a diagonal flux at right angles thereto is established and the identity of the subsequently read out digit is distinguishable by its polarity in the digitsense line. Alternatively a " 0 " may be stored by the absence of a digit write pulse 1d.
