Title: Method and apparatus for flattening metal strip or sheet
IPC: B21D1/05
Filed: 1963-08-20
Abstract: 989,999. Straightening. VOSS ENGINEERING CO. Aug. 20, 1963 [Sept. 4, 1962], No. 32868/63. Heading B3E. A method of flattening metal strip, e.g. of copper, aluminium, brass and carbon alloy steel coldrolled, in gauges of 0.040 inch or less and of any width comprises feeding strip from a payoff reel 1 to a first bridle unit 2 having motor-driven rolls 15, 16, 17 through a conventional roller leveller unit 3 having driven rolls 20, to a second bridle unit 4 having motor driven rolls 24, 25, 26, looping it via guide idler roller conveyer 29, 33 into and out of a pit 35 over a horizontal inspection table 6, through a third bridle unit 7 having driven rolls 36, 37, 38, through a shear 8 which crops off ends of the strip and finally through deflector rolls 40, 41 to a motor-driven winding reel 10. The driven rollers of the first bridle unit 2 produce a back tension on the strip during its travel to the leveller whilst the second unit 4 produces a forward tension thereon on the exit side of the leveller. The speed of the rolls of the third unit 7 relative to unit 2 is adjusted to form the loop 31 and thereby ensure that the strip has zero tension during its travel over the table 6. The speed of the reel 10 tensions the strip as it leaves the unit 7. An adjustable inclined inspection table 42 may be used to facilitate flatness checking of thin gauge material, e.g. 0.010 inch thick. The table is positioned on the exit side of a three-roll second bridle and on the entrance side of the loop. The bridle units may be replaced by conventional pinch roll stands.

Title: Improvements in or relating to the production of heat resistant bodies of molybdenumdisilicide
IPC: C22C29/18
Filed: 1957-10-22
Abstract: Heat resistant bodies of molybdenum disilicide are produced by mixing the finely divided disilicide with 0.2-20% by weight of a finely divided plastic clay of the montmorillonite group suspended in a polar liquid such as water, shaping the mixture, sintering at 1000-1400 DEG C and then heating in the presence of oxygen at about 1600 DEG C.  Clay, which may be bentonite, is preferably used in an amount depending inversely on the grain size of the silicide which should be less than 10 microns.  The silicide may be mixed and kneaded under vacuum with bentonite and water, extruded to rods pre-sintered under pure hydrogen at 1000 DEG C, and sintered at 1200-1400 DEG C under pure hydrogen after which the rods have a porosity of 15-20%.  The rods are then heated for a few minutes in air at 1600 DEG C.  At this temperature the rods may be subjected to a shaping operation.  The product has a porosity of 0-5%.  A typical bentonite used has the composition 60% SiO2, 20% Al2O3, 15% H2O and 5% impurities.  The final product may have a composition 57.7% Mo, 34.9% Si, 0.7% Al, 0.7% Fe, 5.8% O and 0.2% impurities

Abstract: 783,439. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Ltd. Nov. 10, 1955 [Nov. 15, 1954], No. 33048/54. Class 97(3) [Also in Group XXXV] In apparatus comprising a' rigid body, such as a gyroscope rotor case, supported on a base in such a way as to allow the body to respond through a limited range to a torque about any axis parallel to a given plane, and an electro-mechanical force applier having a coil rigidly mounted on the rigid body and a magnet mounted on the base so that when the coil is energized the force applier exerts a force between the body and the base, means are provided for adjusting the magnet to vary the line of action of the force occurring between the coil and the magnet in order to adjust the direction of the axis of the resultant torque. The apparatus may include more than one torque applier. As shown in Fig. 1, the gyroscope rotor casing 1 is suspended as by gimbals or a ligament suspension so as to rotate freely through a small range about any axis perpendicular to the spin axis 2 of the gyroscope rotor. Brackets 3, 4, 5 and 6 are mounted symmetrically round the rotor casing, and are acted upon by a set of eight force appliers. Some of these force appliers are shown in part only, or omitted, in Fig. 1. Each force applier is similar to the moving coil arrangement commonly used in loud-speakers, and consists of a coil 12 embedded in a cylinder or cup of plastic, and a "pot" magnet 13 in the form of a cup 14 and a central post 15. Each coil lies in the annular air gap between the poles of the associated "pot magnet. The coils are connected to the brackets 3, 4, 5 and 6, and the " pot " magnets 13 are mounted on a base (not shown). Opposite pairs of coils are connected so that, when energized together, they assist each other in producing a couple about an axis perpendicular to the gyro spin axis 2. If the post 15 of the pot magnets were exactly cylindrical, the couple would lie in the median plane of the force appliers. The line of action of the force produced by any force applier is made adjustable by forming the central post 15 with a flat 16, and rotating it by means of a gear 18. The line of action of the forces of each set of torque appliers can thus be arranged to lie in the median plane of the torque appliers, so that the resulting torque lies wholly within this plane.

Abstract: 1316857 Treating corrugated fibreboard COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION 8 July 1970 [9 July 1969] 33079/70 Heading D1L Corrugated fibreboard comprising a corrugated layer sandwiched between two liners is treated with a liquid (e.g. a liquid wax or bituminous compound, an adhesive or polymer precursor) in its internal channels by applying slugs of the liquid to successive channels at one edge of the moving, horizontal board, and drawing them across the channels by a pressure differential. As described the edges of the board pass between two shoes 4, 6. A partial vacuum is drawn at shoe 6. Shoe 4 is divided into three regions; 14 where the channels are blocked off and thus evacuated; 16 where the liquid is supplied; and 17 which is vented to the air. The length of region 17 is variable by moving slide 18. Excess liquid is removed and recycled. The board is conveyed between two impervious belts (7, 8) which assist in maintaining vacuum. The liquid may be supplied under a positive pressure and if this is high enough the vacuum may be dispensed with. In such case the belts (7, 8) are not needed. The board may be heated and/or cooled before and/or after treatment.

Abstract: 1,224,043. Production of alkali metal salts of nitrilotriacetic acid. BADISCHE ANILIN & SODA-FABRIK A.G. 11 July, 1968 [12 July, 1967], No. 33093/68. Heading C2C. A process for the continuous production of alkali metal salts of nitrilotriacetic acid from alkali metal cyanide, formaldehyde and ammonia, comprises carrying out the reaction in at least two stages, wherein in a first stage alkali metal cyanide is reacted with formaldehyde in a stoichiometric or substantially stoichiometric ratio at temperatures of 50-200 C. and a pressure of 2 to 50 atmospheres gauge in the presence of excess ammonia to form a solution which contains predominantly aminoacetate, and treating the solution thus obtained after depressurizing to atmospheric pressure in a further stage or in several further stages whilst simultaneously removing ammonia with further amounts of alkali metal cyanide and formaldehyde at temperatures of 60-110 C. to effect conversion of the aminoacetic acid to nitrotriacetic acid. The different stages of the process are preferably effected in separate vessels and the reaction may be effected in the presence or absence of added base. The ammonia may be removed in the second and subsequent stages of the reaction by the passage of a gas which is inert under the reaction conditions, e.g. N 2 , O 2  or steam. Small amounts of by-products, e.g. aminoacetic acid and iminodiacetic acid salts, may also be formed.
