Patent GB-1121189-A (GB)
Title: A method of treating iron powder
IPC: C22C33/02
Filed: 1966-02-25
Abstract: A method of treating iron powder to increase its compressibility, comprises the steps of coldworking the powder to form a powder aggregate, pulverizing the aggregate to reduce the particle size, oxidizing the powder thus obtained to an H2-loss value of between 1% and 10% and then reducing the powder in hydrogen.  The coldworking is performed by rolling and while this operation alone increases the compressibility of the powder obtained by the subsequent pulverizing, it also reduces the green strength of the compact.  By oxidizing the powder, preferably to an H2-loss value of 5% and then reducing it in dry hydrogen at 960 DEG C. for 60 mins., the green strength is increased again.  After reduction the particle size is reduced to less than 0.15 m.m.

Abstract: 1,174,042. Flying shears. UNITED ENG. & FOUNDRY CO. 21 Feb., 1967 [25 Feb., 1966], No. 8537/66. Heading B3W. A flying shear comprises a pair of shafts for displacing severing means carried by the shafts into cutting engagement with a workpiece, motor and flywheel means providing first and second sources of torque which are continuous and constant during the cutting cycle, a first drive train including a clutch which drives the cutters at a speed synchronous with the work during the cutting portion of the cycle, and a second drive train, including a clutch which drives the cutters during a part of the remainder of the cycle at a speed such that the desired length of work material passes through the shear between cuts. The cutters (23) and 23a are each mounted on a crank carried by a shaft, the two shafts being geared together. One of the shafts 15 is supported in bearings 18 and 19 and has secured to it a spur wheel 25, which is in constant mesh with two pinions 27 and 27a. The pinion 27 is part of the primary drive train and the pinion 27a is part of the identical secondary drive train. The pinion 27 is mounted on a shaft 28 supported by a bearing 29 in the housing 9 and bearings 32 mounted in a sleeve 31 which is itself supported in bearings 33. The output member of a clutch 34 is connected to the shaft 28 and the input member is driven by the sleeve 31 which carries a spur gear 35 meshing with a pinion 36 driven by a motor 42. Operation.-The motor 42 runs at a speed which synchronizes the speed of the cutters (23), 23a with the work feed-speed and the clutch 34 is engaging during that part of the cycle when the material is sheared. After shearing the clutch 34 is dis-engaged and the clutch 34a engaged so that the cutters are now driven at a lesser or greater speed than the strip and the amount of strip which passes between cuts varies accordingly. A brake 26 is fitted to the shaft 15 and is used to locate the cutters in a starting position.

Filed: 1933-03-22
Abstract: <PICT:0415179/III/1> In a process for digesting animal or fish offal or bones with steam or solvent, the albuminoid liquor obtained after removing fats, oils and solid materials is treated with chlorine and an acid to remove odours and precipitate solid tissue.  Fish offal is fed into a rotating screening drum mounted in a digester B to which steam or a solvent is admitted.  The liquid and solid products pass through a filter press C, and the filtrate is conducted to a settling tank D containing chambers 13, 14, 15. Oil rises and is removed in chambers 13, 14 and the liquor passes under a partition to the chamber 15.  The albuminoid liquor is then introduced into a tank A which is supplied with a current of chlorine and air through a diffuser 3, and sulphuric acid is then added, whereby tissue present in the liquor is precipitated and freed from oil.  Gaseous products pass through a pipe 7 to the space above the settling chambers, and the liquor passes through a strainer E to a filter H in which precipitated tissue is removed. The filtrate is received in a tank K containing baffles, and is drawn off near the bottom into steam heated still N to form a concentrated glue solution which is then fed into a reservoir 18. The glue may be mixed with solid products removed from the filter pass C and dried to form fish or meat meal. The chamber A may be divided into two similar compartments one of which is being filled while the other is being emptied.  The digester B may be of the form described in Specification 374,166.

Title: Improvements in friction type hinge and pivot joints for door, sash and wind shield mountings and stays
IPC: E05C17/34
Filed: 1920-03-30
Abstract: 163,869. Heffernan, E. March 30, 1920. Holders for sliding windows.-Jointed stays for supporting and retaining in desired positions wind-screens, sliding doors, sliding windows, &c., for example railway carriage windows, Fig. 1, comprise two similar members 10, 11 pivoted at 12 and attached to the window frame 16, and to the top rail 25 of the window sash 26 respectively. The end of each member 10, 11 is expanded into a ring as shown at 13, and each ring encirles a disc 27 through which are bored holes into which cork plugs 14 are fitted. The faces of the plugs project slightly above and below the faces of the discs 27 and press on the one side against a base-plate 15, a flange 17 of which is attached to the window frame, and on the other side against a cover disc 21 rigidly secured on the squared head 20 of a pivot-pin 19 formed integrally with the base-plate 15 and passing through the disc 27. Pockets 28 are provided in the ring 13, in which steel balls 30 are placed. On raising the window, the ring 13 may thus be rotated independently of the disc 27, and consequently no frictional resistance to the movement of the window is experienced; but on the completion of the window-raising movement, the tendency of the window to fall is prevented by the balls, which fall under the action of gravity, and lock the disc 27 and the ring so that they can now only rotate together, but are prevented from so doing by the friction that occurs between the cork plugs 14 and the cover 21 and base-plate 15. Modifications are described for use with doors, wind-screens on automobiles, horizontal sliding doors, &c. One frictional hinge joint may be provided at the pivoting point of the two hinge members instead of the two frictional joints at the free ends of the members.

Filed: 1974-02-28
Abstract: 1445276 Bleaching cellulose pulp INTERNATIONAL PAPER CO 28 Feb 1974 [7 March 1973] 9218/74 Heading D1P Oxygen bleaching of cellulose pulp in alkaline aqueous suspension is effected by applying an initial pressure to the pulp having oxygen dissolved and finely dispersed therein so as to agglomerate bubbles, the maximum permitted bottle diameter being 1/16 inch, and thereafter gradually reducing the pressure without substantial agitation of the slurry, to provide a pressure gradient of between 1 and 10 atmospheres, the temperature being between 70 and 120C, the pulp consistency from 2-10% by weight and the pH between 9 and 14, and the addition of cellulose degradation inhibitors, e.g. magnesium carbonate, being unnecessary. The pressure gradient may be applied by passing the pulp slurry upwardly through a vertical tower preferably between 40 and 300 feet tall. A prepressurisation of up to 300 psig may be applied briefly to the slurry before entering the tower. The oxygen may be intimately dispersed and dissolved in the slurry by a high-shear agitator to provide 0.1-4% by weight of oxygen in the slurry, agglomerated bubbles being subsequently vented to atmosphere before the pressure gradient is applied. The process may be a continuous one utilising conventional pulp bleaching towers, etc.
