Title: Improvements in the Manufacture of Pigments.
Inventor: WOLTERECK HERMAN CHARLES
Filed: 1899-02-02
Granted: 1899-04-01
Abstract: 2382. Woltereck, H. C. Feb. 2. Pigments.-Relates to apparatus &c. for producing pigments such as white lead, zinc white, cinnabar, zinc and tin lakes, &c., by electrolysis. The conditions necessary for the production of pigments are :-(1) The electrolyte must be kept at a constant temperature, and must be continuously circulated. (2) The chemicals required for the regeneration of the electrolyte must be introduced outside the sphere of influence of the current. (3) The product must be continuously removed from the electrolyte. Figs. 1 and 3 show the apparatus used. The electrolysing-tanks 6, 7, 8, 9 are each fitted with a circulating-pump 11 and a dynamo 1 as shown on the tank 6, Fig. 1, the electrodes being arranged alternately as usual. The cathodes are hollow, and are heated by hot water or steam supplied by pipes 23 and 24 as shown in Fig. 3. The electrolyte is fed through a tube 25 having cross-tubes provided with slits which distribute the fluid uniformly. The pigment produced falls through funnels formed in the bottom of the tanks, and passes through a tube 14 into a tank 15 from which it is forced by a pump 16 through filterpresses 17, 18, 19, which separate the pigment. The fluid then passes to a regenerator 20, and back to the electrolysing tanks. In making white lead, the anode is formed of lead, and the electrolyte is composed of an aqueous solution of ammonium nitrate and ammonium carbonate. The nitric acid formed on the anode by the current dissolves the lead, which is precipitated as carbonate by the ammonium carbonate. The ammonia left in the liquid after filtering is reconverted into ammonium carbonate by introducing carbon dioxide.

Abstract: 10,434. Raky, A. May 17. Deep-boring.-Relates to means for adjustably counterbalancing the weight of rotary boring rods and tools. The rods, or the frame b in which they are mounted and driven, are carried by the rope d wound on the drum f, which is geared by multiplying-gearing m to a drum k. As the rods descend, this drum winds up the balance weight g by the rope h passing over the guide-pulleys shown to the third drum l, which can be turned by worm gearing to lengthen the rope h and so lower the weight again. The drum k is also connected by belting to the hand-wheel p, which can be turned in one direction or the other to increase or decrease the pressure due to the balance weight. In a modification, the rope h is arranged as an endless rope to avoid winding it backwards and forwards as the weight rises and falls. In another modification, the frame b is provided with racks which drive a pulley over which passes endless rope arranged somewhat similarly to that in the previous modification.

Title: Improved Mechanism for Feeding the Inking Ribbons of Typewriting and like Machines.
Filed: 1899-09-12
Granted: 1899-12-02
Abstract: 18,428. Turner, R., and Duplex Typewriter Co. Sept. 12. Type-writers and like machines.- Relates to mechanism for feeding the inking-ribbon in typewriters and like machines, and is illustrated as applied to the Jewett or Duplex machine. The mechanism is designed to reciprocate the ribbon widthwise simultaneously with its longitudinal movement. A spring drum e attached to the carriage drives a sleeve g having a ratchet connection with the cylinder k, so that the latter is only turned during the forward movement of the carriage. The cylinder k is provided with inclined cam-ways l, m, which act upon a pin carried by a vertical rack n so as to cause the reciprocation of the rack. The rack drives a pinion q on a shaft p which carries two other pinions gearing with the teeth t formed on the shafts s of the ribbon-spools u arranged at opposite sides of the machine. The to-and-fro movement of these shafts causes a widthwise reciprocation of the ribbon. The shafts bear ratchet discs v at their forward ends, and one or other of these discs is in engagement with a pair of pawls w which produce a step by-step and unidirectional rotation of the shafts in consequence of their endwise movement. When the ribbon is completely transferred from one spool to the other, the opposite set of pawls is thrown into action to reverse the movement.
