Abstract: 558,623. Pantographic apparatus. ROBINSON, Ltd., E. S. & A., FOWERAKER, T. S., and THOMSON, K. June 8, 1942, No. 7802. [Class 97 (iii)] [Also in Group XVI] Apparatus for making contour-line drawings by scanning a scale model or actual aircraft, ship, boat or the like to facilitate the fitting of ribs, partitions &c. comprises a carriage embodying means whereby the model or craft may be turned angularly with respect to the plane of movement of a scanning member so that the model or craft can be posed in any desired position, and means for moving the scanning member in a plane to follow the contour of the model &c. As shown, a model 1 to be scanned is secured to trunnions k rotatable and vertically adjustable on a slide 8. The slide is movable along a base b which is rotatable about a vertical pivot thus allowing the model to be posed in any desired position. The model is scanned by a point u carried by a counterbalanced rise-and-fall bar s which also carries a pencil w or engraving tool making contact with a copy board x. Electric means may be provided so that when the scanning point makes contact with the model, the pencil or engraving tool makes a dot on the copy board, the contour being formed by joining the dots. In use, the scanning point is made to pass slowly over the upper portion of the contour of the model, the carriage r being thereby displaced laterally and a drawing of the contour being made on the copy board. The lower portion of the contour is drawn by first turning the model about the trunnions k through 180 degrees and inverting the copy board, the angular setting of the base b being appropriately reversed, if necessary, by the aid of graduations c. Horizontal and vertical grid lines may be marked on the copy board by stopping off first the vertical and then the horizontal movement of the marking point u.

In making, for example, a crown cork, the top 23 of which has a matte coating of tin 24, on which is superimposed, e.g. by printing a design 25, a metal strip is passed through an acid pickling bath, is rinsed and passed with a protective film of water to an electrolytic bath, up and down which it travels in a vertical direction. The bath may contain 5.4 to 13 ounces sodium stannate, 2 to 5 ounces sodium acetate, and 1 to 3 ounces caustic soda per gallon of water. 1 to 6 ounces of sodium cyanide per gallon of water may also be added to ensure uniform consumption of the anodes. The current density may vary from 10 to 75 amperes per square foot of cathode and the temperature may vary from 158‹ F. to 200‹ F. The weight of the coating is adjusted by varying the rate of travel of the strip or the current density or both. The coated metal may be decorated in strip form or cut into sheets and printed with designs before being stamped to form closure shells. Varnish or sizing coats may be applied before, after or before and after the decorative coating is applied. The superimposed coating may constitute the background and the exposed tin coating the decoration.

Abstract: 377,176. Printing. RITZERFELD, W., 107, Liitzowstrasse, Berlin. March 16, 1931, No. 8013. [Class 100 (ii).] Copying documents, drawings, and the like; printing-surfaces; printing processes.-In a process for copying documents, drawings, addresses, &c., as described, for instance, in Specification 311,330, [Class 100 (ii), Printing processes &c.], in which an original sheet bearing a mirror copy in hectograph ink on the back is utilized to print copies on to moistened copy sheets, the moistening liquid consists mainly of alcohol, to which are added one or more solvents, such as benzol, toluol, or benzyl alcohol, and one or more plasticizers, such as glycerine or phthalic acid ester ; the added substances reduce the ink-dissolving action of the alcohol and therefore increase the number of copies produced. A specific example comprises methylated spirit, benzol, benzyl alcohol, glycerine, and diethyl ester of phthalic acid. The efficiency of the process is further increased by the employment of particular materials for the original and copy sheets. The original is written or typewritten on paper which is not thin, but is very soft and smooth, and, preferably, is heavily loaded with chalk, e.g., art printing paper or chromo paper, whereby the characters stand out in relief on the reverse side of the paper and therefore print more clearly and the ink is not absorbed by the paper but remains on the surface ; also, paper of this kind resists tearing or cutting by the stylus or typewriter. The copy sheets are made of very cloudy, non-translucent, semiglazed, non-absorbent paper containing but little wood cellulose, such as machine glazed paper, which by resisting penetration below its surface absorbs very little ink and liquid.

Title: Improvements in production of titanium
IPC: C25C7/06
Filed: 1961-03-07
Abstract: 910,573. Preparing titanium electrolytically. NEW JERSEY ZINC CO. March 7, 1961 [March 29, 1960], No. 8288/61. Class 41. In the preparation of titanium by electrolysis of a fused halide salt bath containing TiCl 2  and TiCl 3 , in which titanium is deposited on the perforated cathode surface distal from the anode, and introducing TiCl 4 , preferably with an inert gas into the catholyte region, (a) the electrolyte contains free titanium either formed by electrolysis or added thereto, (b) the supply of TiCl 4  is interrupted when a maximum concentration of titanium in solution is attained consistent with maintaining the porosity of the metal deposited on the cathode, e.g. 2 to 5% by weight, and then applying an additional electrolysing current from a second electrode placed in the catholyte, the additional current being up to 35% of the normal current, until titanium concentration falls to about 1% when the supply of TiCl 4  is resumed. A suitable apparatus comprises a deposition cathode having openings 7 in the zone immersed in the fused salt bath 2, an impervious bottom 4 and top 5, and a lining 8 of screen material, e.g. of nickel alloy. The anode comprises a chlorine dome 9 of nickel lined with silica or alumina, immersed at the lower end in the fused electrolyte, in which is mounted a carbon electrode 13. TiCl 4  is supplied through an inlet 15 together with argon into catholyte zone B. Unabsorbed TiCl 4  is recovered from an outlet 16. A second electrode 20, anodic to the deposition electrode, is provided with a wire mesh of nickel 19. Voltage is maintained sufficiently high to deplete the molten bath A of titanium, down to about 1%, and is achieved by energizing the additional electrode 20. At this level of titanium concentration in bath A, and to prevent decomposition of the electrolyte, the supply of TiCl 4  is resumed, and the supplemental current from electrode 20 is interr pted. The back E.M.F. is maintained at 2.4 to 3.2V. during addition of TiCl 4 , and is stopped and additional electrode energized when a voltage of 3.2 is attained. The fused electrolyte may be a mixture of alkali metal and earth metal halides. Examples of eutectic mixtures are given. Specifications 772,892, 811,881, 865,266 and U.S.A.

Filed: 1962-03-05
Abstract: 970,181. Spray-producers. ERSTE MASCHINENFABRIK KARL-MARX-STADT VEB. March 5, 1962, No. 8393/62. Heading B2F. [Also in Division Dl] A liquid spray device comprises a spray tube 3 having perforations in the walls thereof along the length of the tube, at least one partition 14, 15 located within the tube 3 to define compartments 4, 5, 6 in the tube in the longitudinal direction thereof and liquid supply pipes 7, 8, 9 connected to the compartments 4, 5, 6, which pipes 7, 8, 9 can be regulated and shut off. The device is used to restore the surface 2, comprising a cotton cover, of a flexible roller 1 in a calender. The liquid is supplied from a gravity tank 10 which may be in the form of a bar extending above and connecting the sides of the calender rollers. Magnetic valves 11, 12, 13 regulating the pipes 7, 8, 9 can be actuated either by press buttons or by time switches. Pistons 14, 15 provided with threaded spindles 16, 17 which are rotatable but axially fixed define the compartments 4, 5, 6, guide rods 20, 21 preventing rotation of the pistons 14, 15. In use, the pistons 14, 15 are first positioned to adjust the size of the compartments 4, 5, 6 according to the location of the depressions on the cover 2. As the roller 1 rotates continuously the cover 2 is thoroughly moistened and made to swell. The liquid supply is cut off, and the roller 1 is heated indirectly and rotated until it is dry. The procedure may be repeated. A feed device for a soaking agent, if used, comes into operation in dependence on the liquid level in the tank 10 measured on an instrument 31. The agent is held in concentrated form in a flexible bag 28 in a rigid tank 25 filled with water. The tank 25 is connected, through a pipe 26, to a pipe 27 supplying fresh water and the bag 28 is also connected, through a pipe 29, to the pipe 27. When valves 30, 39 are open water pressure acts on the bag 28 to cause the soaking agent to flow continuously into the pipe 27, the valve 30 being opened when the level in the tank 10 falls below that desired. The amounts of soaking agent and water are regulated by a throttle valve 35 and a valve 33 respectively. If the bag 28 becomes nearly empty the valve 39 is closed and the tank 25 emptied through a pipe 37, an air escape valve also being opened. The soaking agent is thus sucked into the bag 28 through a branch 40. Valves 36, 41 are then closed and the valve 39 opened and the valve 38 is closed after the tank 25 is full.
