Patent GB-1304883-A (GB)
IPC: B65G53/30
Filed: 1970-05-13
Abstract: 1304883 Conveying solids in liquids SNAM PROGETTI SpA 13 May 1970 [13 May 1969] 23087/70 Heading F1R A method for transferring in a controlled manner, a solid material in a liquid phase e.g. benzene, xylene toluene comprises the steps of introducing into a vessel 2 containing a liquid phase, a metered amount of solid material in a liquid phase from 1 via 3, 5, pressurizing the contents of the vessel 2 with air or inert gas, via a duct having a valve 4, discharging the solid material and some liquid phase via a valve 6 to a duct 9, reducing the pressurisation of the vessel via valve 4 and restoring the original liquid phase level in the vessel via a duct, controlled by valve 7 using a level regulator 8. In a modification, Fig.2, (not shown), the liquid in which the solid phase e.g. finely divided particles of thorium and plutonium hydroxides and ammonium uranate is dispersed initially may be exchanged by the method for one which has a density higher than that of the first liquid but lower than that of the solid phase. An extra level regulator (10) and valved duct (9) are therefore provided in the apparatus for restoring the amount of second liquid. The duct controlled by valve 7 is in this case used to discharge the initial or first liquid from the vessel.

Title: Improvements in the colouring of cellulose acetate or synthetic linear polyamide textile materials
Inventor: OLPIN HENRY CHARLES
IPC: D06P3/82
Filed: 1956-07-26
Abstract: Textile material of cellulose acetate or synthetic linear polyamides is coloured by applying thereto a metallised unsulphonated azo dye or a metallised unsulphonated azomethine dye in an aqueous liquid containing an organic swelling agent for the material.  Suitable dyes are formed by metallising e.g. with chromium, copper, cobalt or nickel, azo dyes in which the azo group unites two carbon atoms, one of which is directly attached to a carbon atom carrying a hydroxyl group while the other is directly attached to a carbon atom which carries a hydroxyl group, an amino group, a carboxyl group or a carboxylmethoxy group.  The carbon atoms attached to the azo groups and the adjacent carbon atoms carrying the hydroxyls or other groups may form part of a benzene or a heterocyclic ring or of an open chain. Suitable parent azo dyes are obtainable by coupling a diazotised g  orthoaminophenol with 2- naphthol or a nuclear substitution product thereof having the 1- position free for coupling, with a 1-naphthol which couples in the 2- position, with an arylamide, with a 3- methyl -5- pyrazolone or with an arylamide of acetoacetic acid.  Other suitable dyes are unsulphonated "Cibalon," "Orasol," "Irgalan," "Irgacet" (all Registered Trade Marks) and Zapon dyes.  Suitable organic swelling agents are methyl, ethyl and normal and isopropyl alcohols and mixtures thereof, water-miscible ketones, e.g. acetone and diacetonealcohol, water-miscible esters, e.g. ethyl-lactate, and water-miscible ethers, esters or ether-esters of glycol, glycerol or di-ethylene glycol, the etherifying group preferably being a C1-C3 alkyl group and the esterifying group preferably being that of formic or acetic acid.  The proportion of organic swelling agent used is preferably at least 10%, based on the weight of swelling agent and water together, and a thiocyanate, e.g. ammonium, sodium, potassium or zinc thiocyanate, is preferably used in conjunction with the swelling agent in a proportion of 1,5-15%, based on the weight of the liquid components of the composition.  The textile materials may be mechanically impregnated with the dye preparations by padding or printing, in which case the preparations may be thickened with methyl cellulose or gum tragacanth and may contain urea, thiourea or resorcinol; the materials are then washed off in water, with or without preliminary drying, and then steamed. Alternatively, the materials may be allowed to take up the dye substantively from the dye liquor.  The method is applicable to the colouring of cellulose acetate having an acetyl value of at least 59%, calculated as acetic acid, or acetone-soluble cellulose acetate, alone or in combination with natural cellulosic fibres, e.g. cotton, regenerated cellulose fibres or wool.  The Provisional Specification refers to the use in the process of metallised dyes which may contain sulphonic groups.

Abstract: 650,878. Aircraft undercarriages. ELECTROHYDRAULICS, Ltd. Oct. 20, 1947, No. 23128. [Class 4] [Also in Group XXIX] In a fluid pressure system for actuating the steerable wheels on an aircraft undercarriage and of the kind comprising a fluidpressure actuating motor controlled by a selector valve device and a followup mechanism and with a centralizing device between the initial control member, and the wheels, the latter can normally move freely under the action of external forces but, when the control member is initially displaced relative to the wheels, the latter become locked and a further relative displacement of the control member causes the motor to drive them in a sense to reduce the displacement. In an embodiment, the wheels 108 are carried by a tube 105 slidable in a leg 100. The actuating mechanism comprises two single acting jack pistons 125 interconnected by a rack in mesh with a toothed quadrant which is connected by curved toggle links 120, 119 to a sleeve 114 rotatable relative to the leg 100. The toothed quadrant is also connected through gearing to a torque rod 137 to provide a repeatback or follow-up signal, the rotation of rod 137 being communicated to a further rod 143 through a knee-joint 142. Sleeve 114 is connected to tube 105 by toggle links 116 and carries a cam 110 which co-operates with a further cam 111 on tube 105 to allow of centering when the wheels are extended. A shock absorber 113 is fixed to the axle bracket of the wheels and is rotatably mounted in a flange 117 in the leg.

Title: Improvements in swings for recreation
IPC: A63G9/00
Filed: 1921-08-31
Abstract: 186,796. Jofeh, J. Aug. 31, 1921. Swings. - A swing is provided with means whereby the occupant can be rotated about an axis at right angles to the swing during its operation. In the construction shown in Fig. 1, a car body 5 is suspended by and rotatable on a shaft 10 which oscillates upon a crossbar 12. A sprocket-wheel 18 fixed to the lower end of the shaft 10 is geared by means of chains 19, 24 and a shaft 21 with a shaft 26 journaled in the floor of the car. Thus the rider, by turning the shaft 26 by means of a hand-wheel 28, is able to turn the car about the axis of the shaft 10. The seat 2 may be fixed in the car or it may slide on rails 3. In a modification, the shaft 10 is elongated and the seat is pivoted on its lower end, the hand-wheel in this case being fixed to the shaft. In a further modification, the seat is pivoted between side, members which are suspended from the shaft 10. The rotation of the seat may be effected automatically by means of a 'toothed wheel 50, Fig. 6, which engages a rack 51 pivoted on the framework. By means of latches 54, 159, which are engaged by an arm 152 on the shaft 10, the rack is brought into the path of the wheel 50 and then drawn out of it during the reverse movement. The device may be fitted with a brake consisting of a band 71, Fig. 7, surrounding a drum 70 secured to the sleeve 11 and operated by a hand-lever 72. A projection 79 on the lever rests on a drum 77 which is turned by the drum 70 by means of ratchet gear 75. The projection 79 falls into a perforation 78 in the drum 77, and thus applies the brake, after the swing has made a certain number of oscillations. A counting-device 81 may be operated by the ratchet-wheel 75.

Title: Pit prop
IPC: E21D15/28
Filed: 1954-08-10
Abstract: 764,892. Pit props. THINES, H. L. Aug. 10, 1954 [Aug. 11, 1953], No. 23240/54. Class 20(2) A tubular telescopic pit prop comprises a locking device which incorporates a retractable member (1a, Fig. 1; or 11, Fig. 3) which is positively actuated by the telescopic movement of the inner tube within the outer tube in such a manner as first to increase the clamping pressure of the locking device and thereafter to limit the clamping pressure upon cessation of the movement of the retractable member. In Fig. 1, the locking device includes a locking jaw 5 which is initially forced against the inner tube 4 when a transverse wedge 7 is driven in. A member 1, pivotally mounted relatively to the jaw 5 has two arms 1a which engage with two rows of teeth of a rack 9 formed on the inner tube 4. Telescopic movement of the tubes 3 and 4 causes positive rotation of the member 1 through the rack 9 and arms 1a, which increases the clamping pressure. After a certain degree of rotation the arms 1a disengage from the rack 9 and thereafter continued telescopic movement of the tube 4 carries the jaw 5 downwardly by frictional engagement. The clamping pressure is eventually limited by the engagement of arms 1b on the member 1 with inclined surfaces 10 on the tube 4. In an alternative embodiment, Fig. 3, the locking device includes a drag wedge 15 which is positively displaced during telescopic movement between the prop tubes 13, 14, due to the engagement of a retractable member 11 carried by the wedge with a rack 19 on the inner tube 4. The member 11 is retained in engagement with the rack 19 by a guide 16 which is inclined so that the member 11 gradually retracts and eventually disengages from the rack 9 before downward movement of the wedge, and thus the clamping force of the lock is limited by engagement of the member 11 with a stop 17.

Filed: 1977-06-01
Abstract: 1535670 Data processing INTERNATIONAL BUSINESS MACHINE CORP 1 June 1977 [30 June 1976] 23243/77 Heading G4A In a data processing system comprising (control) storage 6 which is organized in page frames 0-63 at least some of which are for relocatable pages, a match between a set target (virtual) address 22 and a currently active (real) address in storage 6 is detected (specifically for diagnostic purposes) by means of a word address comparator 28 and an individual latch (in a register 60) for each page frame in the relocatable area of storage 6. A particular latch is set (when address matching is called for) when the page part of the target address is matched by the (virtual) page address currently allocated to the associated page frame, and a complete match is detected, 15, when a word address match is signalled by the comparator 28 concurrently with accessing of that particular page frame. Matching of the page addresses of relocatable pages is performed by the normal processor facilities under microprogram control to avoid the use of an expensive and slow special purpose comparator. In the case of address matching being required in resident (non- relocatable) storage, the page address comparison is performed by a page address comparator 24 which is of lesser width (corresponding to the number of page frames 0-55 of resident storage) than the width required for page address comparison for relocatable pages. Non-resident page frames 56-63 are assigned to different programs which are run in sequential time slices 1-8. A diagnostic program may be temporarily or permanently assigned time slice 8. Accessing of each particular relocatable page frame is signalled by a time slice control 12. When a page is entered in a relocatable page frame 56-63 its full address is loaded into a special store (80), Fig. 2 (not shown), having a location for each time slice (except possibly time slice 8). The target address is also loaded into local storage for time slice 8, and the program assigned this time slice is arranged to effect the sequential comparison of the page addresses in the different time slice locations of the special store with the target address from the time slice 8 local storage.

Abstract: 1387005 Fluid-pressure servomotor systems TRANE CO 18 May 1972 [20 May 1971]  23478/72 Heading G3P A damper 16 regulating an air flow at substantially constant temperature in a ventilation system and normally controlled by a temperatureresponsive valve 42 is controlled by a pressureresponsive valve 61 when the flow exceeds a predetermined value. Both valves are supplied through a restrictor 32 and adjust the pressure applied to a spring-loaded servopiston 22. When the predetermined air flow is reached, pressures at probes 47 and 49 increase and decrease, respectively, and cause a diaphragm 54 to lift the valve 61. Pressure on the piston 22 is thus decreased and the damper is moved towards its closed position by the spring. In a second embodiment, the positions of the probes are reversed so that the valve 61 is closed at the predetermined value of air flow and produces a higher pressure than the valve 42. This higher pressure is selected by a relay for transmission to the servopiston which in this case is moved against its spring load towards the closed position of the damper. The valves are fed through separate restrictors and the restrictor for the pressure-responsive valve may be of larger diameter to ensure that a higher control pressure is produced. The limitation of the rate of air-flow prevents the distribution system from generating excessive noise.
