Title: Tractor with transverse beam for supporting an implement
IPC: A01D67/00
Filed: 1973-04-24
Abstract: 1415451 Tractor hitches JOHN DEERE SA 24 April 1973 [21 April 1972] 19219/73 Heading A1P A tractor has a transversely extending beam 20 pivotally mounted on spindles 23 and 24 on the two lower draft links 15 (one only shown in Fig. 2) of a three point hitch for supporting a mounted or semi-mounted side operating implement 50. A U-shaped frame 25 also pivotally mounted on spindles 23 and 24 is coupled at the front end 32 by a coupling pin or a chain 34 to the tractor chassis 5. A bracket 35 secured to the frame 25 has an elbow lever 41 pivotally mounted at 40 and articulated at its upper end by an hydraulic jack 42 and at its lower end by a link 43. The rear ends (as seen in the direction of travel) of the jack 42 and link 43 have a common connection to the beam 20 at the coupling pin 45. Operation of the jack 42 from the normal tractor hydraulic system moves the beam 20 about the spindles 23 and 24 and hence alters the working height of the implement 50. The beam 20, frame 25, with jack 42 and linkages are at a sufficiently low level to permit a trailer 12 with draw bar 11 to be attached to the tractor upper draft hitch 10. The jack and linkage attachments to the beam 20 may be lowered further by a modified arrangement as in Fig. 3 (not shown). Power from the take-off shaft 52 is transmitted to the implement 50 via the shaft 53, stub shaft 51, and bevel gearing and drive shaft within the beam 20. The beam and drive to the implement may be made telescopically adjustable. The weight of the implement tends to twist the beam 20 anti-clockwise in Fig. 2, so that some of the implement weight is transferred to the tractor chassis via the frame 25 and chain 24, thus relieving the load on the lower links 15.

Two slides 2 are moveable to and from each other on a bed 4 and each is provided with a vertically-movable clamp co-operating with a guide 9 on the slide. The ends of the strip projecting from the clamps are trimmed by vertically-moving knives 10 which coact with surfaces on an anvil 16, Fig. 1 (not shown), movable vertically to and from a position between the slides; the knives are heated in order to render the cut ends of the strip tacky so as to facilitate the subsequent splicing operation. Each slide 2 is movable by links 30, 32 connected to a strip 34 which is rotatable by a link 38 acted upon by the piston rod 41 of a pneumatic cylinder 42. Each shaft 34 is also connected by links 58, 60 with a pivoted holder 46 for a brush 44 co-operating with the corresponding knife 18. In operation, the strip is draped over supports and secured by the clamps on the two slides where the latter are retracted, the anvil is positioned between the slides, and the knives are moved upwardly to form the projecting ends of the strip. The cylinders 42 are then caused to actuate the shafts 34 so as to retract the slides 2 and provide clearance for the withdrawal of the knives and anvil. Reverse operation of the shafts 34 by the cylinders then swings the brushes 44 upwardly over the knives so as to clean them and also moves the slides inwardly to bring the cut and tacky ends of the strip into engagement. Specification 712,571, [Group VIII], is referred to.

Title: Process for the production and recovery of metals
IPC: G03C5/395
Filed: 1937-07-14
Abstract: Aqueous liquors such as waste photographic liquors containing silver are treated for the recovery of metal by adding a flocculating agent to deposit a sludge containing metal and an auxiliary precipitate, separating the clear liquor, adding an agent such as an acid or alkali which dissolves the auxiliary precipitate and thereby reduces the volume of the sludge, and recovering the metal from the remaining sludge.  The dissolved precipitate may be used as the flocculating agent for further quantities of liquor.  A soluble chloride may be added to the liquor before treatment with the flocculating agent to diminish the solubility of the silver.  The flocculating agent may be aluminium sulphate, sodium aluminate, copper sulphate or ferric chloride, and before its addition the pH value of the liquor may be adjusted to 6-8.  An aqueous extract of the slag resulting from smelting the sludge with alkaline fluxes may be used as precipitant in the earlier part of the process.ALSO:Aqueous liquors such as waste photographic liquors containing silver are treated for the recovery of metal by adding a flocculating agent to deposit a sludge containing metal and an auxiliary precipitate, separating the clear liquor, adding an agent such as an acid or alkali which dissolves the auxiliary precipitate and thereby reduces the volume of the sludge, and recovering the metal from the remaining sludge.

Title: Improvements in and relating to formes carrying surface designs for use in printing or embossing
Inventor: NORRIS WALTER WILLIAM GEORGE
IPC: B41C3/02
Filed: 1962-05-23
Abstract: 1,045,674. Printing - surfaces. COURTAULDS Ltd. May 22, 1963 [May 23, 1962; Sept. 5, 1962], Nos. 19799/62 and 33979/62. Heading B6C. [Also in Divisions B5 and F2] A forme for use in relief or intaglio printing is produced by casting a liquid polymerizable material within a hollow rotatable cylinder having a raised or indented design on its internal surface and effecting polymerization of the material in contact with the design while the cylinder is being rotated about its longitudinal axis. In one example, a design is prepared on a brass sheet by known photomechanical techniques and the sheet is rolled up and inserted in a rotatable copper cylinder which is chromium-plated on its internal surface and adapted to be readily dismantled. The brass sheet is centrifugally forced into place and doses of an epoxy resin and a catalyst are added to the rotating cylinder at intervals. After centrifugal moulding the printing cylinder formed is washed, dried, and heated in an oven to complete the hardening. The casting is subsequently mounted on a shaft with suitable end attachments to provide a gravure printing roller. The casting may have a reinforcement of fibre glass or of a rigid cylinder rotatably mounted within the outer cylinder during casting and adapted to be keyed with the resin. A light-sensitive colloid may itself be centrifugally deposited as a thin film on the internal surface of the rotating cylinder and the design production then occurs in situ. The design may alternatively be produced by a xerographic method. The casting cylinder may be provided with a main compartment and an auxiliary one separated by a weir so as to produce a cylinder of the desired diameter. The design-carrying brass sheet referred to above may be positioned on a liner of epoxy resin already formed by centrifugal moulding. The cast printing surface may be cut into sections or flattened for use on a flat plate.

Filed: 1930-07-01
Abstract: 351,744. Examining gems. NAAMLOOZE VENNOOTSCHAP GLOEILAMPENFABRIEKEN, 13A, Emmasingel, Eindhoven, Holland. July 1, 1930, No. 19976. Convention date, July 15, 1929. [Classes 97 (i) and 98 (i).] For examining crystalline bodies, e.g. pearls, by X-rays, a radiation box fitted with means for holding a pearl, or one or more of a string of pearls, has a cylindrical fitting 5, Fig. 2, for attachment to the window of an X-ray tube which is encased in an earthed metal envelope. The box comprises a tray 6, and may have either a cover for visual observation of fluorescence, or a casette holder attachment for photographic purposes. A tray surround 35 is fitted for catching loose pearls. Entrance of rays into the box is restricted by a lead diaphragm 8 to a central opening 11 and two lead tubes 27, 28 with narrow bores directed to the focal spot of the tube. For viewing purposes a cover 19 either wholly of lead glass or with a lead glass window 20 fits on the tray 6. A spring- controlled cut-off shutter 23 normally closes the channel 11 and is opened when the cover 19 is positioned by cam lever 24, Fig. 4, on the outside of the tray. The pearl is positioned over the aperture 14 in the tray 6 above the aperture 11 and a string of pearls may be passed through the channel groove 16 coaxial with openings 15, Fig. 2, in the edge of the cover 19. A light spring 17, e.g. of celluloid, holds the pearls in position. The cover 19 may carry a viewing hood 21 fitted with binocular magnifying glasses 22. For photographic purposes the cover 19 is replaced by a film or plate casette holder 26, Fig. 3. This holder is notched so as not to depress the cam lever 24 and open the cut-off 23. The pearls are placed at the ends 29, 30 of the tubes 27, 28, and a string of pearls may be passed across through openings 31, 32 in the rim of the table 6. Light springs 33, 34 for holding the pearl are provided. Two lead discs 36, 37 are positioned on the holder 26 to prevent action by direct X-rays on the photographic plate which would be prejudicial to the definition of the interference diagrams. A small central aperture may, however, be provided in one of the lead discs, resulting in a black spot and serving for identification purposes.

Filed: 1943-11-30
Abstract: 573,254. Variable-speed ratchet gearing. C.-W. ENGINEERING CO., Ltd., and SANDERS, J. H. Nov. 30, 1943, No. 20004. [Class 80 (ii)] Relates to ratchet gearing in which a feeding pawl 22 on an oscillatable lever 14 engages a ratchet wheel 12, the number of teeth of which that can be engaged by the pawl 22 being controlled by a cam 44 on a slipper plate 42. The latter can be adjusted by a knob 52 connected to a worm 48 engaging teeth 46 on the slipper plate 42. A check pawl 28 pivoted on a fixed pivot 30 prevents return movement of the ratchet wheel 12, According to the invention, holding means associated with the check pawl is arranged to engage the slipper plate and hold the latter against the reaction of the feed pawl when the feed pawl is moving backwards for disengagement from the ratchet wheel and the check pawl is manually disengaged from the ratchet wheel. As shown, the slipper plate 42 has a notch 78 providing a shoulder 80. A pivoted lever 74 has a lug 84 adjacent the stem 40 of the pawl 28 and a lug 82 adjacent the perimeter of the slipper plate 42. A handle 66 is connected to the stem 40 by links 58, 60. In operation, when it is desired to release the load, the knob 52 is operated until the pawl 22 can engage only a single tooth. This brings the shoulder 80 in line with the lug 82. During the feeding stroke, the handle 66 is pulled to release the check pawl 28 and cause the stem 40 to engage the lug 84 and move the lug 82 into the notch 78. On the return movement of the lever 14, the pawl 22 is forcedly removed from the ratchet wheel 12 which spins backwardly to relieve the load. The engagement of the lug 82 with the shoulder 80 prevents the blow reacting on the slipper plate adjusting gear 46, 48, 52.

Title: Improvements in titanium pigments, and process of preparation thereof
IPC: C09C1/00
Filed: 1924-08-25
Abstract: 243,081. Klein, C. A., and Brown, R. S. Aug. 25, 1924. Pigments.-In a process for producing a titanium pigment having a base of barium sulphate, a slag of barium and titanium oxides, containing some metallic iron, is obtained by fusing a titanium ore, such as rutile or ilmenite, with a barium compound, such as barium carbonate, with or without a flux such as fluorspar and a reducing agent. If barium sulphate is used instead of barium carbonate, it is first heated with the titanium ore, such heating resulting in the formation of sulphuric acid fumes, and the resulting mixture of barium, titanium, and iron oxides is fused with carbon to form the slag. The bulk of the iron is removed from the slag in any suitable manner. The slag is then crushed and preferably treated with magnets, and formed into a paste with sulphuric acid, which may be formed from the fumes obtained as above described. The mixture of titanium and barium sulphates so formed is run into boiling water in the presence of organic materials such as aldehydes, sugar, starch, &c. This process effects the precipitation of titanium compounds on to the barium sulphate, while the organic materials prevent the precipitation of iron. The product is washed, dried, and calcined in the presence of air to burn off any carbon, and finally ground. The Provisional Specification states that the process results in the preparation of titanium dioxide on to the barium sulphate.
