Title: Improvements in or relating to the electrolytic deposition on a workpiece
IPC: C25D5/02
Filed: 1962-02-15
Abstract: <PICT:1000721/C6-C7/1> <PICT:1000721/C6-C7/2> A process of providing an electrolytic deposit on one face only of the surface of a workpiece comprises disposing the workpiece as cathode in the electrolyte of an electrolytic cell between the anode of the cell and a secondary cathode wth the surface of the workpiece on which the deposit is to be effected directed towards the anode and applying an electric potential across the cell so that the potential difference between the workpiece and the secondary cathode has a value between zero and the voltage of dissolving of the workpiece in the particular electrolyte employed.  Fig. 2 shows an anode A and a workpiece B with the cell container serving as a secondary cathode C. A shunt resistance R1 is less than the electrolyte resistance R between the workpieces and secondary cathode.  Metal is plated on the workpiece surface facing the anode but the small current which passes through the electrolyte between B and C is sufficient to prevent metal deposition on the workpiece surface remote from the anode.  As shown in Fig. 4, the negative pole of a current source is alternately connected to B and C, e.g. to B for 50 seconds and to C for 10 seconds.  Fig. 5 (not shown) illustrates an embodiment where the current is periodically reversed for short periods. Several cells may be connected in series.  Some examples are of plating Pb and Pb-Sn from fluoborate baths containing the Pb or Pb and Sn fluoborates, free HBF4 and gelatine. Some baths also contain free H3BO3. There are two examples of electroplating Pb-Sn on a Cu-Pb lining to steel, one of electroplating Pb on a bronze (80% Cu, 10% Pb, 10% Sn) lining to steel and one of electroplating Cu on a steel sheet from a bath containing copper cyanide, free NaCN and NaHSO3.

Title: A process of making artificial dispersions of rubber in water
IPC: C08J3/03
Filed: 1932-03-02
Abstract: The invention of the parent Specification which consists in dispersing plasticized rubber in a stiff aqueous paste of a water-soluble colloid and an attrition agent such as whiting, slate dust, or diatomaceous earth, is modified by (1) plasticizing the rubber first with an organic colloid and subsequently dispersing the mixture in an aqueous paste of a non-colloidal mineral powder; (2) plasticizing the rubber with an inert non-colloidal mineral filler and subsequently dispersing the mixture in an aqueous paste containing a non-colloidal mineral powder and an organic colloid; (3) employing as the organic colloid water-soluble gums such as locust bean gum, gum arabic, gum tragacanth, baraya gum, starches, dextrins, and other carbohydrate colloids, or casein.  Examples: (1) 300 parts of reclaim rubber are plasticized by milling with a fluxing agent such as cumar resin, pine tar, mineral rubber, or 10-25 parts of rosin, with or without up to 50 per cent of whiting or the like; the mixture is then added, in a steam-jacketed masticator, to a paste containing locust bean gum 10-40 parts, whiting 100-300 parts, water 100-250 parts.  Water, vulcanizing agents, vulcanization accelerators, &c. are added as required and the finished dispersion diluted if necessary with water; (2) the paste in (1) is replaced by starch, 40-60 parts, whiting 100-300 parts, water 100-250 parts; caustic soda (2-20 per cent of the weight of starch employed) may be added to the dispersion, before or after dilution, in order to transform the starch into vegetable glue. In addition to the uses referred to in the parent Specification the products may be employed in the manufacture of waterproof paper.  Specification 351,427 is referred to.

Abstract: 318,098. Bowser & Co., Inc., S. F., (Assignees of Bond, R. W., and Renfrew, P. B.). Aug. 27, 1928, [Convention date]. Direct air-pressure apparatus, non- automatic.-In a plant for dispensing liquids by air pressure, liquid passes from a storage tank 9, Fig. 1, through a non-return valve 14, Fig. 2, into a chamber 11 when the latter is not under pressure; subsequent introduction of compressed air forces liquid through a pipe 63, air-release fitting 72, and pipes 82, 83, 84 to the fittings 30, 31. The valve 14 is carried by a casting 18 screwed into place and removable from the exterior of the tank 9 by a rod 22. The fittings 30, 31 are provided with operating levers 40, the raising of a lever 40 acting through a link 48, Fig. 4, rod 50, lever 52, and spindle 54 to open a valve 57 to place conduits 33, 28 into communication for the admission of compressed air to the chamber 11. When the lever is lowered, the valve 57 is closed and a valve 123 opened to put the chamber 11 to exhaust through conduits 28, 38. Operation of the lever 40 to open the valve 57 simultaneously through a link 101 opens a valve 91 to permit the liquid to flow through a metering device to a delivery hose 97. The hose nozzle may have an outlet valve opened by a lever 110, or a hand-operated valve 115 is provided. When the hose is out of use, it may be inserted through a hole in the casing 46 ; a plate 119 carries a stop member 121 which prevents movement of the plate and the insertion of the hose when the lever 40 is raised, but wnen the lever is down, the plate is moved by the hose nozzle so that the stop member takes up a position to prevent lifting of the lever. The compressed air system has a diaphragm-controlled reducing valve 127 and safety valves 141, the latter comprising a member 145, Fig. 8, loaded by a spring 146 adjustable by a screw 149. Sediment may be forced out of the chamber 11 through a pipe 158 after removing a plug 156.
