Title: Copra mfr. from coconuts - using nut splitting machine followed by drying in hot air rotary drums
IPC: A23N5/03
Filed: 1976-03-08
Abstract: Nuts are gravity fed into a shell splitting machine. The nuts enter the splitter through a vertical tunnel in which one or two balanced dividing plates align each nut in turn to pass into the splitting cutters. The cutters are 3 or 4 symmetrically spaced, chopping discs rotating in vertical planes. The splitting machine delivers on to a sorting grille where small waste and pieces of shell already sepd. are removed. Coconut milk is recovered via a strainer from the machine. Sepn. of kernel from shell is then carried out in a hot air rotary drum drier with adjustable internal stirring blades. Waste shell is sepd. and kernel passed onto a second, longer, rotary drum where the copra is fully dried by hot air. Dry waste from all stages is burned to produce hot water which, in turn, heats the air blown into the rotary drying drums. Process is continuous, and takes about 23-26 hrs. compared with 5-9 days when natural drying is used after manual splitting. The prod. is white and free from bacteria.

Title: Cleaning coke-oven door edges - using rotary tool transported by articulated arms and held against surfaces by springs, eliminating hand-work
Inventor: BOIDIN GERARD
IPC: C10B43/04
Filed: 1977-03-25
Abstract: Method comprises using an appts. which includes a stand which can be placed opposite a door, a mechanism mounted on the stand adapted to operate a cleaning tool and motors for actuating the mechanism. The mechanism incorporates an arm articulated on a support and a beam mounted with its centre at the other end of the arm and able to rotate about that centre. A tool carrier is mounted at one end of, and perpendicular to, the beam. In operation the arm rotates slowly and the beam carries the tool, which is rotating at e.g. 300 r.p. min, so that the side of the tool cleans one face and the nose of the tool cleans another face of the shaped element at the edge of the door which ensures gas-tight closure. Springs hold the tool against the surfaces in both directions. The angle of attack of the tool is maintained constant during the cleaning operation. Problems associated with the use of scrapers and brushes mounted on an endless chain, or a scraper actuated by a jack, necessitating considerable hand work in difficult conditions, are avoided.

Title: Recovery of particulate crystalline product during electrolysis - using agitators to sweep product from cathodes onto conveyor
Inventor: COOK MELVIN S
IPC: C25C5/02
Filed: 1977-04-07
Abstract: Process comprises agitating the electrolyte to cause the product to separate from the cathodes. The product is collected on a conveyor and removed from the electrolytic tank through a washing zone to displace electrolyte from the product. Agitation is effected by flexible arms on each side of each cathode which oscillate about a horizontal shaft. The conveyor passes along a conduit which is inclined at about 45 degrees to the electrolytic tank. Pref. system is for prodn. of particulate crystalline Cu from cuprous chloride soln. Agitation aids control of th crystalline product size and density and the structural competence of the dendrites. The product is collected without handling or disturbing the cathodes. Dendritic growth into the anode zones is prevented thus preventing short circuiting. Operation at high current densities results in a fewer number of cells required and a reduction in cell maintenance. The washing zone displaces valuable ingredients so that they are retained in the tank.
