IPC: B65F3/04
Filed: 1956-11-21
Abstract: 809,172. Refuse vehicles; tipping bins. NEDERLANDSCHE TANK - APPARATENEN MACHINEFABRIEK NETAM N.V. Nov. 21, 1956, No. 35659/56. Class 78 (4). A bin-supporting rod 7 (Fig. 3), supported for tipping in brackets 3 at the rear of a refuse vehicle is prevented from leaving the brackets 3 by projections 13 carried by a cradle 8 which helps to support the bin. As illustrated the cradle 8 is pivoted about a shaft 22 so that the projections 13 are moved over the rod 7 as the bin is tipped. A sector 17 (Fig. 1), moving with the cradle 8 meshes with a sector 18 which opens a flap 21 at the rear of the vehicle. The gears 17, 18 are preferably sufficiently heavy to provide a flywheel effect making the tipping action smoother, and the gears may be shaped to give a preferred variation in velocity ratio. Three devices such as that illustrated may be mounted side-by-side at the rear of the vehicle.

Patent GB-349563-A (GB)
Title: Process for extracting metals from ores, minerals and other materials
IPC: C22B3/04
Filed: 1929-11-29
Abstract: Ores and other metalliferous materials are leached with neutral, acid, or basic solutions containing ammonia and sulphur dioxide without the application of external heat and with exclusion of air or other oxidizing agents.  Metal values may be recovered from the solutions obtained by boiling, neutralization, precipitation as sulphides or hydroxides, electrolysis, or hydrolysis at elevated temperatures or by dilution with water.  In all methods the leaching liquor is ultimately regenerated and may be returned to the process. Specified applications of the process are the extraction of zinc from blue powder or zinc dust, of copper from oxidized ores &c., of tin from tin plate &c., of vanadium, nickel and cobalt from their oxidized ores, and of copper, arsenic and antimony from materials containing them. Basic solutions are more effective for leaching oxides of copper, gold, silver, zinc, cadmium, mercury, cobalt and nickel, and acid solutions for metallic tin, oxides of arsenic, antimony, and bismuth, chromic acid, molybdenum and uranium oxides; whilst vanadium oxides are attacked equally by both basic and acid solutions, and metals and oxides of Group III, oxides of tin and lead, metallic lead, chromic oxide, manganese and manganese dioxide, iron and ferric oxide, and platinum are not susceptible to the leach. Selective leaching may be effected by using first a basic and then an acid liquor or vice versa; in this way copper may be separated from arsenic and antimony.  Alternatively when two or more metals go into solution, one or more may be precipitated by metallic dust; in this way zinc may be separated from copper, or the latter from nickel and cobalt.

Abstract: 398,697. Tapping nuts. CLOUSE, W. L., Tiffin, Ohio, U.S.A. Dec. 30, 1932, No. 36954. [Class 83 (iii).] A nut-tapping machine in which blanks are intermittently fed to a holder where they are rotated relatively to a tap having a curved shank, is provided with a reciprocating table with a nut-guiding channel into which the tap shank fits and with means for adjusting the nuts to place them for entry into the channel. The nuts, fed down a shoot 1, are pushed intermittently into a rotating holder 9 by a plunger 3 which is actuated by mechanism suitably connected to the main driving gear to give the correct timing to the movements ; placer pieces 10 are arranged inside the holder to engage alternate nut faces, their front ends are bevelled and project beyond the holder so that the nuts may be slid smoothly into position, recesses 33 at the back ends of these placer pieces into which the nuts automatically fit on leaving the tap 11 prevent finished nuts from being pushed forward when the table and nutpositioning means are in motion. The table 14 mounted on guides 15, 16 and reciprocated from the main driving shaft 23 by cam and lever mechanism has an arcuate channel 18 along which nuts can slide, a restraining strip 19 is fastened across the ends of the channel to hold the arcuate tap shank, which passes through the centres of the nuts, in place. The nut-positioning means 20 is fastened to the table and serves to turn the nuts into the correct position for entry into the channel 18 as the table moves forward ; the finished nuts pass out of the channel into a receptacle, not shown.
