Abstract: 998,496. Rolling; preparing ingots. F. D. CARTWRIGHT. July 10, 1963 [April 10, 1962], No. 13865/62. Headings B3A and B3M A method of controlling the directional, mechanical, and crystallographic properties of an elongated article includes the steps of feeding the article in a number of passes between at least one pair of coacting rolls, the articles being fed to the rolls in each pass at an acute angle to a line normal to the roll axes and emerging from the rolls along the normal line. A strip 7 is fed by rolls 6 at an angle #to the normal of rolls 1 and emerges in a direction D1. The strip may be returned along a path C2 between the rolls or may pass to a further roll set. Supporting rollers 2 of the rolls 1 are rotated in directions A1 and A2, thus causing planetary rollers 3, mounted in rotatable frames 5, to rotate in directions B1 and B2. Nine successive rolling steps in which # is 10 degrees gives a total angular displacement of 90 degrees. Strips, billets, slabs, and sections may be rolled, the article being rolled on all four sides if desired. The ends of a billet to be rolled may be shaped (Fig. 5, not shown), in order to minimize end losses in the finished product.

Title: Improvements in and relating to electric transmission lines and applications thereof
IPC: H01P9/00
Filed: 1944-07-19
Abstract: 611,611. Delay lines. BRITISH THOMSONHOUSTON CO., Ltd. July 19, 1944, No. 13871. Convention date, July 19, 1943. [Class 40 (viii)] [Also in Groups XXXVI and XL (c)] A high-frequency transmission line having a low velocity of propagation and high characteristic impedance comprises a pair of coils 11, 12 oppositely wound on a flexible former 13 of insulating material with the turns of one coil slightly inclined to the turns of the other. Preferably, the coils are of copper wire covered with enamel and the former is of moulded resinous material such as polyvinylidene chloride. The distributed inductance per unit length is four times as great as that of one of the coils alone, and the distributed capacity of the line is the capacity between the coils. The cut-off frequency can be raised by reducing the diameter of the coils. The line may be used for delaying a pulse in relation to the time-base of a cathode-ray oscilloscope, or as part of a circuit for generating square pulses, and can be coiled when a long length is required. In a generator of square pulses, an open circuited length of the delay line 11, 12 forms the anode load of a thyratron or the like 23, output being taken from a cathode load 22 whose impedance is equal to the characteristic impedance of the line 11, 12. While the thyratron is in non- conducting state the line 11, 12 is charged by a battery 19 through a decoupling resistance 20, but trigger pulses periodically applied to the grid from a source 24 cause the line to discharge through the thyratron, which subsequently cuts off owing to this voltage drop in resistance 20. A pulse with enhanced power is thus emitted from the anode load 22.

Title: Method and apparatus for stacking tiles
IPC: B65G57/11
Filed: 1964-04-03
Abstract: 1,063,088. Sheet delivering and stacking apparatus. U. WALCHHUTTER. April 3, 1964 [April 11, 1963; March 26, 1964], No: 13878/64. Heading B6H. Tiles supported on a movable upper conveyer 12 are delivered to a tile supporting member 21 resting on a stacking table 1, which is attached to a ram 2 lowered incrementally by the depth of one tile on each successive delivery of a tile. The delivery of each tile is sensed by a photoelectric cell C1 which generates a signal which is applied to an electrically controlled valve E1, which passes a metered quantity of hydraulic fluid through a throttle valve S and conduit 8 to the upper side of the ram cylinder 3. The ram is supported on the obverse side by compressed air supplied from a compressor 5 and forming a compressible cushion. The photo-electric cell C1 also applies a signal to a reverse counter, which when the number of tiles has reached a preselected value causes the valve E1 to open continuously to lower the stacking table 1 until the tile supporting member 21 contacts a lower conveyer 13, which is then driven by a motor MT2 whilst the motor MT1 of the upper conveyer 12 is stopped. Simultaneously with the lowering of the stacking table 1 a valve E4 is open to displace a further tile supporting member 21 on to the conveyer 13 from a pile 19 of such supporting members and the further tile supporting member is transferred to the top of the stacking table 1 during the course of removal of the tile stack by the moving conveyer 13. The valve E1 is then closed and a valve E2, which leads to the fluid sump is opened, whereby the ram 2 and the stacking table 1 are raised by the compressed air applied to the cylinder through the conduit 4. When fragile tiles are being delivered and stacked an interposing plate 14 is moved to the delivery end of the conveyer 12 to receive the tile thereon and to deposit it on the stack on its return stroke. The plate 14 is reciprocated by a spring-biased air-operated piston 16<SP>1</SP>. Micro-switches C2, C5, C3 and C4 are cooperating with a rod 18 on the stacking table 1 and the piston rod 16<SP>1</SP>, respectively, to control circuits co-ordinating the stacking cycle.

Title: Improvements in or relating to the manufacture of diamino-diphenoxyanthraquinonedisulphonic acids
IPC: C09B1/54
Filed: 1937-05-19
Abstract: A 1.4-diamino-2.3-diphenoxyanthraquinone disulphonic acid or a homologue thereof obtained by sulphonating 1.4-diamino-2.3-diphenoxyanthraquinone or a homologue is isolated from the sulphonation mass by adjusting the sulphuric acid concentration of the mass to between 45-65 per cent, thus precipitating the sulphate of the 1.4-diamino-2.3-diphenoxyanthraquinonedisulphonic acid.  The sulphate may be filtered off, and converted to the sulphonic acid alkali metal salt of the free amine by treating with a solution of an alkali metal salt such as sodium chloride or carbonate.  The products dye wool red-violet shades.  In examples, 1.4-diamino-2.3-diphenoxyanthraquinone or 1.4-diamino-2.3 di(p-methylphenoxy)-anthraquinone is sulphonated, and the sulphonation mixture poured into sufficient water to give a sulphuric acid concentration of 45-50 per cent.  The invention is also stated to be applicable to 1.4-diamino - 2.3 - di(o- or m-methylphenoxy)-anthraquinone-disulphonic acids.
