Patent GB-190126166-A (GB)
Title: Improvements in the Treatment of Zinc Ore containing Cadmium or otherwise.
Inventor: ELLERSHAUSEN FRANCIS
Filed: 1901-12-21
Granted: 1902-12-18
Abstract: 26,166. Ellershausen, F., and Western, R. W. Dec. 21. Zinc hydrate and oxide.-Zinc ore, calcined, if necessary, is moistened with a solution of ammonium sulphate and then with sulphuric acid. The mass is lixiviated with an ammonium-sulphate solution to dissolve out the zinc and cadmium sulphates, a little calcium carbonate being added to decompose ferric sulphate, if present. Cadmium is precipitated by means of zinc dust, and ammonia is added to the solution to precipitate zinc hydroxide, which may be heated to produce a pigment or may be smelted for the metal. The ammonia for use in the process may be obtained by treating a portion of the ammonium-sulphate solution with lime, while the ammonium - sulphate solution obtained in the process is stored for re-use, thus minimizing the quantity of water to be employed.

Patent GB-190311915-A (GB)
Title: Improvements in Graphophones or Machines for Recording and Reproducing Sounds.
Inventor: JOHNSON JAMES YATE
Filed: 1903-05-25
Granted: 1903-07-30
Abstract: 11,915. Johnson, J. Y., [American Graphophone Co.]. May 25. Graphogphones &c.-In graphophones and like machines, provision is made for a constant linear velocity of that point of the disc on which the stylus is bearing. The radial motion of the arm carrying the stylus operates a brake, which regulates the speed of a centrifugal governor on the motor. Three forms are described, of which Fig. 1 shows a drum 1 enclosing the motor spring which actuates the disc-carrying shaft 27 and the shaft 12. On the shaft 12 are the centrifugal governor 16, spring arms 15, and the sliding block 14 carrying the friction disc 17. As the stylus 33 travels radially on the recording-disc 6, the cam-shaped piece 34, 35 determines the position of the lever 18, pivoted at 19, by means of an adjustable contact screw 36. The distance through which the disc 17 can rise before it is stopped by the brake block 22 on the lever is consequently varied, and thereby the limiting speed of the governor also. A spring keeps the contact-screw against the cam, and a revoluble piece 23 provides for depressing the brake block to stop the motor. In another form, Fig. 3, the cam - plate 54 is within the casing of the instrument upon an arm keyed to the shaft which carries the stylus-supporting arm. Upon the governor spindle 40, Fig. 3, slides a block carrying the friction disc 41 and operated by spring arms, to whieh the balls or weights 42 of the governor are attached. The position of the camplate determines that of the pivoted lever 50, carrymg the brake block 47, and thereby fixes the limiting speed at the instant. The contact-piece is not adjustable, but the milled head 46 and screw spindle 45 upon rotation cause longitudinal motion of the governor spindle by means of the lever 43. The absolute linear velocity at the recording point can thus be adjusted. Fig. 6 shows the third form, having a governor with friction disc 72 and brake block 80 attached to a lever 81, which is kept in contact with a transverse wedge-shaped piece 87 by means of a spring 86. The motor rotates the transverse screw 97 through spur-whee]s 100, 101 and bevel-wheels 102x, 98, thereby causing transverse motion of the segmental nut 105, and with it the carriage 91, sleeve 93, and arm 94 carrying the wedge 87. These all slide upon the tube 95 and produce a radial motion of the stylus, which is supported by the arm 120 on the carriage 91, and also a corresponding variation in the speed of the motor owing to the consequent change in position of the brake block 80. A cam 85 is provided to depress the spring 84 and lever 81 and so stop the motor. By means of a cam 110, the stylus arm can be raised and the nut simultaneously pulled up against the spring 106 by the rod 107, thereby throwing the traversing mechanism out of gear. To regulate the absolute speed, the screw 89 and lever 75 are provided, whereby the governor shaft can be moved vertically. A horn or mouthpiece may be fitted to the socket 141.

Granted: 1904-06-16
Abstract: 18,785. Crosta, L. W. Sept. 1. Spigot - andsocket joints for earthenware and sanitary pipes. The socket end n is made larger than the spigot end o, as shown in Figs. 1 and 2, so as to admit cement afterwards to make the joint. In order to obtain a true invert, a ring r, r<1>, made of bituminous composition or cement, is cast in the socket n after the pipe is made. At one face, the inside of the ring r is eccentric with regard to the outside of the ring, while at the other face, the inside is concentric with the outside. The thickest part r is at the bottom, so that, when the spigot end o is being inserted, it slides up the sloping portion r, and forms a true invert against the shoulders of the socket.
