IPC: G01N29/06
Filed: 1962-01-11
Abstract: 987,645. Ultrasonic testing. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Jan. 7, 1963 [Jan. 11, 1962], No. 1157/62. Heading H4D. In an arrangement for depicting the internal structure of materials a specimen of material 1 is " scanned " by an ultrasonic transmitter 7 and receiver 8 the vertical movement of which is produced by a cam 4 driven by motor 2 and the horizontal movement of which is produced by a motor 11 and pinion 12 coacting with a rack 13 associated with one of two tracks 10. The transmitter 7, which is pulsed at a repetition frequency of 500 p.p.s. with 5 microsecond pulses from a generator 20 controlled by a trigger circuit 21, produces a collimated beam which is scattered or attenuated to an extent dependent on the grain size of the specimen so that the intensity of the ultrasonic energy received by transducer 8 is indicative of the grain structure. The latter is then depicted in rectangular coordinaters by supplying the output signals from transducer 8 via a gate circuit 22 (opened by trigger 21 after a delay in 24 to ensure that only signals due to transmission through the specimen are passed) and amplifier 23 to the contact bar 8 of a known form of facsimile recorder the helical contact blade 14a of which, carried by drum 14, is driven by motor 2 in accordance with the vertical scan movement and the recording paper 15 of which is driven by motor 11 in accordance with the horizontal scan movement. The recording paper is heat-sensitive and when the intensity of the signals applied to bar 8 is sufficient a blacking of the paper results so that the resulting record consists of light and dark areas depicting the varying grain size. The specimen which is a ¢ inch thick slice cut from a uranium nuclear fuel element of one inch diameter is fixedly mounted in a water tank 6 and the transducers, which comprise lead zirconate 6 Mc/s. elements, effect a vertical scanning movement of about 3 cm. in a period of five seconds and have a horizontal scanning speed such as to produce 80 lines per inch. Specification 930,687 is referred to.

Filed: 1936-01-15
Abstract: 468,958. Fuel - injection pumps. ALCOCK, J. F., and HOLT, G. A. Jan. 15, 1936, No. 1264. [Class 102 (i)] In a fuel-injection pump of the type in which injection is terminated by the opening of a spill port, the spill takes place into a closed chamber against an elastic pressure, and is returned to the pump chamber at the next suction stroke. As shown the suction port F and the spill port G are controlled by the plunger C<1> which has a helical edge C<6> for controlling the spill port. The spill takes place into a chamber K containing an elastic metallic diaphragm K<1> acted on by a spring. A second diaphragm may be provided between the interior of the diaphragm K<1> and the exterior of the pump for giving a visible signal should the diaphragm K<1> break. Alternatively a frangible disc K<3> may be provided which permits discharge of the spill to the suction passage through a pipe K<5>, should the diaphragm K<1> break. The spill passage may enter the chamber K at its highest point, as shown, in order to prevent the accumulation of gases in the chamber. Alternatively a separate passage may be provided, controlled by a hand-operated valve, for the discharge of gases. In a modification the diaphragm K<1> is replaced by a spring-pressed piston. Alternatively, an air cushion is employed, or the compressibility of the fuel provides the required elastic force.

Title: Improved method of purifying mercury which has been used as a cathode in electrolysis
IPC: C22C3/00
Filed: 1932-01-18
Abstract: In a process in which iron, nickel, and cobalt are removed from solutions by electrolytic deposition into a mercury cathode, the contaminated mercury is purified for re-use by treatment with an oxidizing agent, preferably one which may be readily re-oxidized such as ferric sulphate, a hypochlorite or nitric acid.  The oxidizing agent may be employed in an aqueous solution which is preferably kept acid.  It should be present in quantity less than equivalent to the metal impurity in order to avoid attack on the mercury.  The mercury may be continuously circulated between the electrolytic cell and the purification apparatus under such conditions that the proportion of metal impurity is maintained at a substantially constant value not above 0,5 per cent and preferably below 0,3 per cent.  Specification 318,149, [Class 41, Electrolysis], is referred to.
Patent GB-431793-A (GB)
Title: Improvements in or relating to carburettors for internal combustion engines
IPC: F02M9/10
Filed: 1934-01-16
Abstract: 431,793. Spray carburetters. WHITEMAN, J. L., 19, Tessider Avenue, Haverfield, Sydney, Australia. Jan. 16, 1934, No. 1610. [Class 7 (iii)] In a carburetter in which the fuel valve is controlled by a suctionoperated air valve, the air valve is coupled by link mechanism to an outer sleeve of the fuel nozzle. The sleeve is mounted to slide upon spaced guides parallel to the axis of the nozzle and may carry a needle valve the maximum opening of which is determined by a fixed stop in the path of the valve. Exhaust gas or hot water circulates through an annular chamber 56 to heat fuel flowing upwards through a tubular chamber 66 which constitutes an enlargement of the fuel supply pipe 70, 69, and air flows through an adjacent annular chamber 57 to an inlet 18 on the carburetter body. The passage of the air up the body is controlled by suction-actuated flap valves 27 connected by links 29 to an operating bar 25 carrying a pair of rods 21 sliding in guides 20 parallel to the axis of the fuel nozzle. The heads 22 of the rods lie in recesses in a bridge piece 23, and the rods may be adjusted in the operating bar 25 when the bridge piece has been displaced inwards against the action of a spring 24 which urges the flap valves to the closed position. The operating bar 25 is integral with a sleeve 26 slidable on a fixed tube 35, surrounding the fuel nozzle tube 37, and slotted at 50 for the passage of fuel therefrom. An internal flange 47 on the sleeve 26 supports a spring which carries a needle valve 44 adapted to control the outlet of the nozzle, which may be adjusted vertically by a pinion 40 and rack 39 formed on the tube 37. Excessive lift of the valve needle 44 is prevented by a screw 16 which engages the end of the valve stem 46, further movement of the sleeve 26 then compressing the spring carrying the needle valve. Specification 173,563, [Class 7 (iii)], is referred to.

Title: Improvements in or relating to apparatus for driving conveyor belts
IPC: B65G23/19
Filed: 1956-01-18
Abstract: 829,876. Belt conveyer driving gear. EICKHOFF MASCHINENFABRIK UND EISENGIESSEREI GEB. Jan. 18, 1956 [Jan. 19, 1955; July 29, 1955], No. 1644/56. Class 78 (1). A conveyer belt is driven by a driving member provided with means adapted to apply suction to the belt, the means comprising a number of spaced open suction mouths in an outer surface of the driving member which communicate with hollow spaces arranged between the outer surface and an endless inner surface of the driving member, adjacent spaces being separated from one another by webs. In one form, Fig. 1, the driving member is a drum 1 composed of inner and outer cylindrical shells between which are disposed webs 3, dividing the annular space thus formed into compartments 4 each of which is open at one or both ends and communicates with a series of bores 5 in the outer shell, the bores having flared suction openings which cover most of the drum surface and are arranged in staggered relationship. Each open end of the drum co-operates with a stationary annular channel-section member connected by a pipe 10 to a suction apparatus, this member being divided into two chambers by partitions 8, 9 designed respectively to admit and cut off air gradually from each of the compartments 4 as they pass in succession to and from the chamber to which suction is applied. The other chamber is connected to an air filter 11 which cleans and silences the air entering the compartments 4 to relieve the suction as they pass in turn beyond the point at which the belt 21 leaves the drum, so that suction is applied gradually to the belt as it passes on to the drum and is gradually removed as the belt leaves the drum. In a second form, Figs. 7, 8, 12 and 13, the belt 22 is driven at an intermediate location between head and tail pulleys by an underlying endless driving belt 29 formed with a series of transverse suction chambers 30 opening at points along their length to the underside of the conveyer belt and at their ends to the interiors of guide blocks 25 for the side edges of that portion of the driving belt which engages the conveyer belt, the interiors of the guide blocks being connected to suction means. The suction chambers may be formed either by constructing the driving belt with upper and lower belts 31, 31a between which are disposed transverse webs, or by providing the driving belt with deep transverse grooves the exposed lateral portions of which are covered by narrow bands 34. In the former construction each chamber communicates by a plurality of slots 37 with shallow transverse grooves in the upper band 30. The guide blocks 25 are provided with rollers 38 for guiding the edges of the driving belt, and both longitudinal and transverse series of inwardly projecting ribs 39, 40 forming a labyrinth seal between the blocks and the engaged portions of the upper and lower faces of the driving belt.

Title: Improvements in and relating to filtering or dewatering presses
IPC: B30B9/26
Filed: 1920-01-19
Abstract: 154,817. Ten Bosch, A. Jan. 19, 1920. Presses.-In piston presses for dewatering peat and like processes, the piston and cylinder head are of hemispherical, conical or like form so that there are gradually diminishing spaces between the piston and cylinder head and the cylinder walls, the liquid escaping through the space between the piston and cylinder head and the walls, and through annular slots in the cylinder walls, piston or cylinder head, the slots being narrow and opening into wider spaces. In the arrangement shown, the cylinder is formed of rings 9, triangular in cross-section, held together by bolts 11 and separated by distance pieces. The cylinder is enclosed in a jacket 14 through which steam can be introduced into the press, and from which water passing between the rings 9 can escape. The piston is built up of disks 6 shaped as shown and separated by distance-pieces 7, so as to give a semicircular contour interrupted by small gaps. These gaps will face, to a certain extent, in the direction of motion of the piston, but the rings may be so shaped as to avoid this, the contour of the piston then departing slightly from a semi-circle. The piston may rotate on its axis, to facilitate the freeing of the briquette produced. The cylinder head may be constructed like the piston, and may act as a second piston.

Abstract: 903,176. Turbine and compressor-bladed rotors. ROLLS-ROYCE Ltd. Jan. 10, 1961 [Jan. 18, 1960], No. 1761/60. Class 110 (3). A method of assembling a rotary bladed member comprises introducing the roots 15 of a number of blades 16, one at a time, into a localized widened portion 14 of a groove 11, moving each blade root 15 within the groove 11 into a position in which shoulders 18, 19 on the roots 15 are respectively engaged behind shoulders 12, 13 bounding the groove 11. Prior to inserting the final blade, a spring-loaded plate 20 is introduced into the widened portion or slot 14 and is pressed towards the disc axis and when disposed inwardly of the shoulders 12, 13 is moved so that it no longer blocks the slot 14. The final blade is then inserted through the slot 14 and the whole blade assembly is moved in the direction of the arrow 24 (Fig. 3). When the plate 20 becomes aligned with the slot 14, a spring 21 moves the plate into the slot and into engagement with platforms 17 of adjacent blades 16. The platforms 17 may be provided with holes for a tool to depress the plate 20 for removal of the blades. To balance the rotor, the combined weight of the plate 20, spring housing 22, 23, and spring 21 may equal the weight of the metal removed to produce the slot 14. Alternatively, two slots, diametrically opposed, each with its own closure member may be provided. A modified form of springing, Fig. 5 (not shown), comprises a stem or peg secured to the plate to which are secured two leaf-springs having upturned ends.

Abstract: 584,717. High-tension switches. MASCHINENFABRIK OERLIKON. Jan. 23, 1945, No. 1838. Convention date, Jan. 24, 1944. [Class 38 (v)] In a pneumatically-actuated gas-blast circuitbreaker having a disconnector switch and a plurality of serially-connected power breaking points, the actuating gas supply to each driving piston is throttled until the piston has moved to uncover the main inlet apertures, effecting simultaneous arc interruption at all breaking points. Stacked, coaxial units each consist of fixed and moving contacts 7, 13, insulators 1, 4 and the necessary actuating gear for the contact 13. To' open the circuit-breaker, compressed gas is admitted to insulating pipes 2, through annular chambers 3 and throttling apertures 16 into a filling chamber 15. The piston 18 moves downwards slowly, uncovering the main apertures 17 and then accelerating, and contact 13 subsequently passes the cylindrical insulating nozzle 6 and compressed gas is thus admitted to the arc, flowing through the contact 13, 7 and escaping through gas cooler 5. By decreasing the ratio of volume of filling chamber to cross-sectional area of throttling apertures for the units progressively further away from the common source of compressed gas, the driving pistons for all units are arranged to accelerate simultaneously.
