Title: Apparatus for making an article from pieces of sheet material
Inventor: MCNAIR JAMES RUSSELL FARRELL
IPC: B26F1/40
Filed: 1963-06-04
Abstract: 970,837. Laminates and laminating. ROLLS-ROYCE Ltd. June 4, 1963, No. 22252/63. Heading B5N. [Also in Division B8] An apparatus for making a compressor blade 36 for a gas turbine engine from pieces of sticky synthetic resin sheet material 35 comprises an endless chain conveyer 10 driven by a sprocket 11 and entrained around an idler 2. A stepwise movement is imparted to the conveyer by a ratchet 12 moved by a double-acting pneumatiram 13. In the course of one cycle platens 14 are carried through twelve punching stations 15. At each station a tape of sticky synthetic resin material 18 backed by paper 23 is fed from a refrigerated enclosure 22 from a metal roll 21 above a platen 14, momentarily at rest at the station, the paper 23 being stripped off the tape 18 by rollers 23, 25, 26. Each station 15 has a punch 16 co-operating with a die 17 to punch out a piece of the tape of predetermined shape, any shock being absorbed by a pad 20. The tape 18, which may be of glass or asbestos fibres impregnated with a phenolic or epoxy resin is reunited with the paper backing 23 and received on a roll 30 in a second refrigerated enclosure 31. Each punch 16 is operated by a pneumatic ram 60, a bottle 61 supplying compressed gas to a valve 63. An electric motor 34 drives the rolls 30 via a belt drive from a shaft 33. The shaft 33 drives a cam shaft 50 which is provided with a cam 51 for each of the stations 15. Each cam 51 has at least one projection 52 arranged to actuate a mercury switch 53 adapted to control one of the punches 16 through a valve 63. The various punches 16 punch from the various tapes 18 pieces 35 which differ in shape from each other (except that the number of pieces punched at any one station is governed by the number of projections 52 on the associated cam 51). The arrangement is such that as a platen 14 moves in turn from one punch 16 to the next it receives piece after piece 35, the various pieces being superimposed so as to form the compressor blade 36. Since the material is sticky each piece 35 is caused to adhere to the underlying pieces by the punching operation itself. The blade 36 is finally placed in a mould (not shown) for final forming and curing of the resin. If the tape 18 on the roll 21 is exhausted a probe 80 contacts the metal of the roll to actuate a warning bell. If not attended to immediately a further circuit (not shown) may be completed to stop the apparatus. The grain 37 of the different pieces 35 extends in different directions either by rotating the platens 14 (Fig. 3, not shown) or feeding the tapes 18 at different angles (Fig. 6, not shown).

Title: Improvements relating to slicing machines
IPC: B26D1/16
Filed: 1927-08-25
Abstract: 276,673. Maatschappij tot Vervaardiging van Snijmachines Volgens van Berkel's Patent en van Andere Werktuigen. Aug. 25, 1926, [Convention date]. Cutting slices in succession.-In a machine for slicing meat containing bones, a rotary disc knife 10 rotates bodily about an eccentric axis, i.e., the driving-shaft 1, but, when desired to exert a chopping action, is rotated non-positively about its own axis, i.e., the shaft 7. Means are provided to make the latter rotation positive. The shaft 1 carries a cranked member 5 which is extended at 6 to carry the shaft 7, and provides a bearing for a shaft 13 coaxial with the shaft 1. The shaft 13 carries a sprocket wheel 12 connected by a chain 11 to a free-wheel sprocket 8. The shaft 13 is normally freely revoluble in the member 5 so that the axial rotation of the knife is non- positive. The end of the shaft 13 is, however, provided with a square recess into which one end of a U-sha.ped brace may be inserted, the other end being received in an opening in the casing 17. The sprocket 12 is then held against rotation and the axial rotation of the knife is positive. For grinding the knife, the arm 6 is locked in its uppermost position by a pin 21 which locks the hand-wheel 2, and a crank handle 14 is inserted in the shaft 13 and is kept in position by a spring 16. The meat is fed along the trough 29 by a member 28 actuated by a feed screw. The free-wheel prevents the rotation of the knife in the wrong direction during grinding. In the modification shown in Fig. 4, the knife shaft 27 is fixed in the arm 6 and the sprocket 8 and associated free-wheel disc 9 to which the knife 10 is attached, are freely revoluble on the shaft 27. In another modification, the sprocket 8 is revoluble with a friction disc which is spring-pressed against a friction disc coupled to the knife.

Title: Apparatus for the hydraulic transmission of power
IPC: F16H45/00
Filed: 1933-08-12
Abstract: 423,947. Hydraulic transmission of power. HASSALL, T. G., 9, Albert Square, and STEPHENS, R. G., 18, Park Avenue, Longsight, both in Manchester. Aug. 12, 1933, No. 22537. [Class 69 (ii)] An apparatus for the hydraulic transmission of power, comprises two intercommunicating rotary vane pumps, one of which is positively driven by the engine, while the other is driven by the engine through a variable-speed clutch comprising a liquid-container 6, Fig. 1, adapted to be rotated by the engine, and an oscillating member 8 in said container adapted to engage and transmit rotary motion to a transmission member 13, due to the centrifugal pressure of the liquid. A vaned rotor 23, keyed to an extension 11 of the casing 6 which is driven from the driving shaft 4, rotates upon the member 13 which is secured to a disc 44 carrying a rotor 27 carrying a brake-drum 21. The rotors 23, 27 are formed and arranged as shown in Fig. 2, the inner one carrying pivoted and sliding vanes 26 moving upon the surface 29 of the second rotor 27 which co-operates with sliding and pivoted vanes 34 upon an outer casing 30, secured to the drum shaft 5. When the engine is idling, the rotors 23, 27 are rotated, but the casing 30 remains stationary owing to the inertia of the system ; as the speed increases, the centrifugal pressure of the liquid in the cylinder 6 is increased and increased motion is accordingly transmitted to the rotors 27 so that the casing 30 and the shaft 5 rotate forwardly. For reverse, a brake band is applied to the drum 21, thus holding the rotors 27 against rotation ; a member 16 secured to the extension 11 is simultaneously moved so that the members 8 and 14 are separated and motion is no longer transmitted to the rotors 27. The device is housed in a casing 1 containing makeup oil which is supplied to the rotor-spaces by pipes 42 having scoops 41. More than one set of pumps may be employed, relatively so arranged that a balanced drive is secured.

Title: Improvements in apparatus for moistening and sealing envelopes
Filed: 1950-09-14
Abstract: <PICT:0685880/III/1> <PICT:0685880/III/2> In an apparatus for moistening and sealing envelopes the envelope is placed on the tray q so that the flap hangs down through the slot u and rests in front of the stop plate h, provided at its lower end with a drip-return flange.  The handle r is then moved to pull the segments e out of the casing a, and at the same time the wick plate g between the segments e is swung up.  The wick plate contacts the flap of the envelope, presses it against stop plate h, and the wicks k protruding through slots in the wick plate moisten the gummed edges of the envelope flap.  The handle r is then released and the springs j pull the segments e back to their original position, whereby the wick plate retires from the envelope flap.  At the same time the pressure rollers d are caused to rotate due to engagement of the lower rollers with the moving segments e, and in this backward stroke the pins z strike the lower arms of the detent levers m which pull the ejectors n in the direction of the pressure rollers d.  The bent up ends of the ejectors grip the back edge of the envelope which is lying in front of them, and push the envelope into the rollers d, which seal and eject it.

Title: Processing aqueous nitric acid solutions containing uranium or plutonium
IPC: C22B60/04
Filed: 1958-07-21
Abstract: 865,778. Separating uranium and plutonium from fission products. UNITED STATES ATOMIC ENERGY COMMISSION. July 21, 1958 [July 26, 1957], No. 23290/58. Class 39(4). An aqueous nitric acid solution containing a predominant concentration of uranium, together withplutonium and fission products, is adjusted to an acidity of 0.3 to 0.5 M, a reducing agent is added to reduce the plutonium to the trivalent state, and the uranium is extracted by contact with tributyl phosphate, leaving plutonium and fission products in the aqueous phase. The invention also comprises a process of separating uranium from an aqueous nitric acid solution of acidity 0.3 to 0.5 M and containing fission products, by contact with tributyl phosphate at a temperature of 60-70C., the uranium being extracted into the organic phase while fission products remain in the aqueous phase. The initial solution may be obtained by dissolving irradiated uranium fuel elements from a nuclear reactor in nitric acid at 130C and 2 atmospheres pressure. The reducing agent may be a ferrous compound, e.g. ferrous ammonium sulphate, together with a holding reductant, e:g. urea, formaldehyde, methyl alcohol, ethyl alcohol, hydrazine, sulphamic acid, or a sulphamate; a solution of ferrous sulphamate provides both agents. The tributyl phosphate may be diluted with an aliphatic naphtha, dibutyl ether, disisopropyl ether, isoamyl acetate, or the dibutyl ester of tetraethylene glycol. The aqueous phase containing plutonium and fission products is treated with an oxidising agent, e.g. sodium nitrite, to convert plutonium to the tetravalent state and then contacted with tributyl phosphate containing some dibutyl phosphate; plutonium passes into the organic phase, leaving fission products in the aqueous phase. The plutonium is returned to aqueous solution by contacting the organic phase with an aqueous solution containing nitric acid and ferrous sulphamate; further purification of the plutonium may be obtained by repeating the oxidation and extraction steps. The tributyl phosphate phase containing uranium may be further decontaminated by scrubbing in three stages, firstly with dilute nitric acid containing ferrous sulphamate to remove plutonium, secondly with more concentrated nitric acid to remove ruthenium, and finally with water to remove nitric acid and zirconium and niobium. Uranium is then precipitated as peroxide or oxalate by contacting the organic solution with an aqueous solution containing hydrogen peroxide or oxalic acid.

Abstract: 362,476. Vehicle door fastenings. FORD MOTOR CO., Ltd., 88, Regent Street, London. Aug. 5, 1930, No. 23481. Convention date, Aug. 31, 1929. [Class 44.] In a latch particularly for vehicle doors comprising outside and inside panels 10, 11 secured to a pillar 12, the outside handle 34 may be locked against operation by a hand-operated member slidable on the inside panel and operating a member slidable across the door pillar. The latch 15, bent as shown to pass round the edge of the sliding glass panel 59, is pivoted at 18 in lugs bent up from an apertured plate 13 secured to the pillar 12 and is biased to locking position by a spring 37. The outside handle 34 operates a follower 22 engaging an extension 16 of the latch. A horizontal rod 43 rotatably mounted by means of dips 42 in a groove in the inner panel 11 has a cranked end 44 engaging a lug 40 on the latch which is withdrawn when rod 43 is oscillated by a handle 46. Rod 43 is biased to normal position by a spring 47. The hub 21 of follower 22 is mounted on a square spindle 28 (provided with the handle 34) between lugs 20, 23 carried by plate 13, a spring 27 biasing follower 22 to the normal latched position. Lug 3 is bent upon itself to form a member 25 provided with a square hole 26 through which the square end of the spindle is passed, a reduced portion 29 then registering with member 25 to allow rotation of the spindle, Hole 26 is disposed so that in normal position the end of spindle 28 is out of register with the hole so that the spindle cannot be withdrawn excert after rotation through 45‹. A sleeved washer 31 serving as a bearing for handle 34 is enclosed by an escutcheon plate 35, members 31, 35 being rotatably and non-slidably secured on the handle by a washer 66 and pin 67, and escutcheon 35 is secured to panel 10 by screws 36. Owing to the disposition of aperture 26 the handle assembly cannot be removed from the door by removal of screws 36 when the handle is locked against rotation. Locking is affected by a member 52 slidably mounted on pillar 12, and normally biased to the right, Figs. 1 and 4, by a spring 69. When moved to the left a projection 68 on member 52 engages a projection 55 on follower 22. Movement of member 52 is effected by a bolt slidably mounted behind panel 11 and having an operating knob 50 working in a slot in the panel. An inclined end of the bolt engages a correspondingly inclined portion 56 of member 52 so that when the bolt is moved upwards, Fig. 4, member 52 is moved to the left. The latch engages a member 62 adjustably secured by bolt and slot 65 within the channelled door-post 64, the bottom of the channel and inner face of member 62 having serrations as shown.

Title: Improvements relating to the catalytic desulphurisation of kerosine and white spirits
IPC: C10G45/30
Filed: 1947-08-26
Abstract: A kerosene or white spirits fraction of petroleum is desulphurized by passing in vapour form in admixture with hydrogen over a catalyst which combines activity for dehydrogenation of naphthenes to aromatics with activity for the conversion of <PICT:0669536/III/1> organically combined sulphur to hydrogen sulphide and which is not poisoned as a catalyst by the presence of sulphur compounds, at a temperature and pressure such that the dehydrogenation of naphthenes present in the fraction is effected to an extent not substantially in excess of that required to produce sufficient hydrogen to convert the organically combined sulphur into hydrogen sulphide and to supply the hydrogen for recycling to the reaction zone to maintain the vapour phase therein.  The temperature used is preferably 700 DEG -800 DEG F and the pressure 50-250 p.s.i.  The recycle rate of the hydrogen may be 4,000-6,000 cu. ft./bbl. of feedstock.  Metal sulphides and oxides, especially those of the 6th group may be used as catalysts, for example chromium oxide, tungsten sulphide, tungsten sulphide and nickel sulphide, and cobalt molybdate or thiomolybdate, and may be mixed with, or deposited on, a porous support such as natural or processed bauxite, activated alumina and kieselguhr.  A pelleted catalyst may be prepared by mixing powdered cobalt oxide, molybdic oxide and alumina, and pelleting with 1 per cent graphite into 3/16th inch pellets which are treated for two hours at 550 DEG C. Alternatively the catalyst may be prepared by extrusion. As shown, an unrefined Iranian kerosene is fed via line 11, heat exchanger 12 and preheater 13 to a reactor 10 charged with cobalt molybdate on alumina.  The products are cooled in cooler 14 and passed to gas separator 15.  The gases separated are recycled to the reaction zone through line 16 at a rate of 4,000 cu. ft./bbl. and the liquid product containing the hydrogen sulphide in solution depressurized in separator 19 from which the hydrogen sulphide is removed via line 20. Specifications 654,152 and 669,553 are referred to.
