Title: Method of Refuse Disposal.
IPC: B30B9/30
Filed: 1966-09-23
Abstract: 1,159,731. Compressing refuse. TEZUKA KOSAN K.K. 23 Sept., 1966 [2 June, 1966], No. 42705/66. Heading B8C. [Also in Division E1] Refuse to be disposed of is unloaded into a chamber 2 of a machine where a piston 6 is extended to compress it in one direction while moisture is expelled through holes 28 in the chamber wall, a second piston 9 compressing it in a second direction against a door 10 which is then moved so that the piston 9 may push the compressed refuse into a tubular wrapper P. The wrapper ends are folded on to the refuse, either manually or by automatic or semiautomatic means, and the package advanced by the piston 9 to a chamber 16 where a piston 19 compresses it against a removable door 24 before a further piston 22 acts on the package side. The door 24 and piston 22 are withdrawn to enable the piston 19 to expel the package. Before or during the first compression stage, the refuse may be treated with a chemical or gas to prevent its decomposition; and the same effect may be achieved by de-aerating the refuse. The moisture may be removed by means of heat or vacuum. The wrapper may be a plastics sheet, e.g. vinyl chloride or polyethylene, reinforced by wire netting; or the sheet may be of unreinforced plastics, or metal foil. Alternatively, a layer of plastics dissolved in an evaporable solvent may be sprayed on to the refuse. Again, a plastics covering, applied between the two main stages of compressing the refuse, may be held in place by a wire net, canvas strips or metal bands applied after the second main compression stage. The various pistons are hydraulically operated.

Title: Data storage systems
IPC: G06F12/00
Filed: 1973-09-17
Abstract: 1438875 Data processing systems INTERNATIONAL BUSINESS MACHINES CORP 17 Sept 1973 [24 Nov 1972] 43458/73 Heading G4A In a system including a plurality of independently addressable storage modules 12, conflicts between access requests from a plurality of regulators A-D are resolved by granting priority of access to individual requestors until all requestors can be granted access to different modules 12 simultaneously. One application of the system is to vector processing in which B-D represent streams of vector elements to be processed and A represents the elements of a result vector. Elements, are stored in modules 12 in interleaved fashion i.e. successive elements of a vector are stored in successive different modules taken in cyclic sequence whereby access to successive elements is obtained by supplying an initial address for the first element and incrementing the address for successive elements, the two low order address bits defining the module 12. As an example, if the initial dadresses of elements A1 B1, C1, D1 are in modules 0, 31 and 1 respectively, initializer 20 detects the conflict between C1 and D1 and controls the access circuitry and delay elements 37-39 so that D1 is accessed alone from module 1 and is subjected to a one memory cycle delay at 39, then all subsequent accesses for all requestors are made simultaneously starting with A1, B1, C1, D2 from modules 0, 3, 1 and 2 respectively. In this way, corresponding elements B, C, D are simultaneously available at an ALU30 while the appropriate module 12 is being addressed to store the corresponding element of the result vector. Delays of up to 3 cycles for D, 2 cycles for C and 1 cycle for B may be selected, the input and output data being gated to the appropriate input or output bus 13, 14 under control of the two lowest address bits from the requestors. Basically similar systems may be provided for simultaneous read-out access to a plurality of channels (with optional provision of selectable delays 37-39), for simultaneous write access from a plurality of channels (delays 37-39 being required in the input data path), and for resolving conflict between requests for assignment of identified resources (e.g. I/O devices, program modules) to requestors when it is necessary to notify the requestor that the resource assigned to it is different from that requested. In the latter case, the outputs of delay selector 22 indicate the difference between the requested and assigned resource for each requester instead of introducing selectable delays. Detailed logic circuits for the individual functional units of Fig. 1 are described.

Abstract: 437,801. Soot blowers. BABCOCK & WILCOX, Ltd., and GLINN, R. J., Babcock House, Farringdon Street, London. May 31, 1935, No. 15941. [Class 99 (ii)] [See also Group XXVI] The blower tube 5 of a boiler cleaner or soot blower is rotated by opposed singleacting pistons 3, 4 which are connected by links 12, 13, 14 and reciprocate within cylinders 1, 2, the reciprocating motion of the pistons being transmitted to a pinion 20 on the blower tube by arms 17, 18 which are engaged by pins 15, 16 between the said links and are provided with pawls 22, 23 engaging pinions 19, 21. The pinion 19 meshes with the pinion 20 and the pinion 21, which is similar to the pinion 19, meshes with the pinion 19 so that rotation of the pinions 19, 21 in opposite directions will effect clockwise rotation of the pinion 20. As shown the pinions 19, 21 and arms 17, 18 are mounted on bolts 8, 9 carried by brackets 10 on the blower, these bolts also supporting by lugs 7 the cylinders 1, 2 which are bolted together in axial alignment. The cylinders are provided with conduits 35, 36 for admitting and exhausting steam or other working fluid alternately to and from the closed ends thereof under the control of a piston valve 24 which is movable in an open-ended chamber 25 mounted on the cylinders and is actuated by a lever 26 fixed on a spindle 27. A lever 31 loose on the spindle 27 is engaged by pins 32 on the reciprocating link 13 and is connected by a spring 29 to a second lever 30 fixed on said spindle, the arrangement being such that the valve 24 is caused to move rapidly from one extreme position to the other on the completion of each stroke of the pistons. The valve chamber 25 is provided with a steam inlet 39 and its open ends constitute exhaust ports. Periods of rest in the rotation of the blower tube may be secured by the provision of slot connections between the pins 15, 16 and the arms 17, 18, and a cam may be associated with the blower tube for operating a release valve to open intermittently the cleaning fluid supply valve of said blower tube and thus provide a puff effect. Specification 337,891, [Class 99 (ii)], is referred to.

[Also in Divisions B7 and F2] The invention relates to a fluid flow control valve and is described with reference to a variable area nozzle of an aircraft vertical lift control nozzle. The nozzle comprises a chamber 12 having an inlet port 20 to which air under pressure is supplied through a duct 22, the chamber having an opening which is closed by a cover member 18 in sealed engagement therewith. The chamber is provided with an outlet nozzle 16 of frusto-conical form. A stationary cylindrical member 28 is disposed within the chamber, the lower end of the member being of conical form 30 and projecting through the nozzle 16 so as to define therewith an annular outlet passage 38 through which air may discharge so as to impart vertical thrust on an aircraft on which the nozzle is mounted, the thrust being controlled by an axially movable cylindrical valve member 40 which varies the area of the outlet passage 38. The stationary member 28 is provided at its upper end with flanges 32 which are secured by bolts to the cover 18. The stationary member is provided on its inner surface with a pair of longitudinally-extending recesses 60, 62 which form a guide for a crosspiece 56 which is integral with a screwed rod portion 58. A cross-piece 64 is secured to the rod portion 58 by means of lock nuts and extends through openings 50, 52 in the wall of the stationary member 28, the openings being extended longitudinally so as to allow axial movement of the cross-piece 64. The cylindrical valve member 40 is secured to the cross-piece by means of screws 66, the valve member being guided on the stationary member 28 by an annular projection 47. A ring 46 mounted in a groove in the member 28 engages the inner surface of the valve member so as to provide a seal therebetween. The cross-piece 56 is formed with a slot 70 in which is disposed a roller 78 carried on a crank pin 76 of a rotatable shaft 74 so that as the shaft 74 is rotated the rod 58 and so the valve member 40 is moved axially. The shaft 74 is rotatably mounted within a cylindrical boss portion 72 of the chamber 12 and carries at its outer end a lever 84 which is angularly movable by a pilot's control lever, movement of the lever 84 being transmitted to the shaft 74 by a double bevel assembly 86. The lever 84 is formed with two tabs or ears which co-operate with a fixed stop to limit angular movement of the lever.

Title: Improvements relating to the measurement of density of fluids within a pipe or the like
IPC: G01N23/203
Filed: 1960-12-22
Abstract: 923,630. Density measurement of gaseous fluids. E. K. COLE Ltd., and D. F. WHITE. Dec. 20, 1961 [Dec. 22, 1960], No. 44015/60. Class 40 (3). The density of a gaseous fluid in a pipe is measured or analysed at points across the pipe, utilizing the Compton effect, by directing a beam of penetrative radiation, such as gamma radiation, diametrically across the pipe and selectively sampling from successive elemental lengths of the beam scatter received by a detector outside the pipe and the direct influence of the beam. As shown, a caesium<SP>137</SP> source 1 of gamma radiation is contained in a collimator 2 and directs a beam 3 across a pipe 4 containing a gaseous fluid. A detector formed by a scintillator 6 and a photo-multiplier 7 mounted outside the pipe has its output fed to a pulse height analyser 9 whose output is fed to a ratemeter 10. The energy of the radiation scattered at different angles by the fluid varies according to the angle through which it is scattered and if the cross-sectional area of the primary beam as it passes through a point O is A, the only radiation able to reach the detector after being scattered through, say, 90 degrees, is that from an element of length d. If then by the pulse height analyser the detector only records rays having an energy level close to that corresponding to a scattering angle of 90 degrees the radiation recorded by the detector can only come from a small volume dA. Thus by adjustment of the energy level to which the detector is responsive, the whole diameter of the pipe may be scanned, enabling the density of the fluid to be determined since the amount of scattered radiation is directly proportional to the density of the fluid within a small elemental volume. In a further embodiment (Fig. 2, not shown) the detector is shielded by a collimator 12 and the detector assembly is arranged to move so as to scan the beam of radiation. In this case the output from the photo-multiplier is fed to a frequency discriminator 13 and then to a ratemeter.
