Title: Maximise the value of a sulphide ore resource through sequential waste rejection
Inventor: FILMER ANTHONY OWEN
IPC: C22B23/00
Filed: 2017-06-30
Abstract: This invention relates to an integrated process for recovering value metals from sulphide ore which includes the steps of bulk sorting 16 and screening 24/28 crushed ore. The sorted and screened coarse ore stream is ground and classified 20 to provide a coarse fraction 34 suitable for coarse flotation and a first fine fraction 38 suitable for flotation. The coarse fraction suitable for coarse flotation is subjected to coarse flotation 36 thereby to obtain a gangue 42 and an intermediate concentrate 46. The intermediate concentrate is subjected to grinding 48 to provide a second fine fraction suitable for conventional flotation. The first fine fraction and the second fine fraction are subjected to conventional flotation 40 to provide a concentrate and tailings. This process that capitalises on the natural heterogeneity of sulphide orebodies, and utilises bulk sorting, screening and coarse flotation beneficiation technologies in a novel multistage configuration to reject the maximum quantity of waste gangue prior to fine comminution.

Title: Closure system for cardboard boxes
IPC: B65D43/16
Filed: 1996-07-04
Abstract: Closure system which can be applied to cardboard boxes, particularly boxes composed of a receptacle and of a lid which are independent or articulated together, which is obtained via a set of cuts and creases made during the normal process of manufacturing the box. The system is composed of a tab 4 which is cut out from and articulated on the upper edge of the receptacle 2 and of a cut-out 3 which exists on the inner edge of the lid 1, which are dimensioned and positioned in such a manner that the tab, when folded outwards 13 and when the lid is fitted, penetrates into the cut-out which exists on the inner edge of the lid, preventing subsequent re-opening of the lid or making such an operation difficult. This system has the principal advantage of easy fastening of the lid of a package in the closure position without having recourse to any additional fastening system, it sufficing, for this purpose, to exert a slight pressure on the lid. <IMAGE>

Printed- circuit board is installed onto locating members of satellite 5 located in upper chain, and the entire chain is compressed to stop thereby providing for precision positioning of printed-circuit boards on site. Slide bars function to displace a number of components in channels until last of components in the row is stopped by guide surface of vertical channel; component is caught by vacuum grip. Then the latter and component caught by it are passed over vertical channel and vacuum grip presses component to desired point on printed-circuit board whereupon it returns to initial position. Finished board is removed from the last satellite 5 of upper chain in unloading position, device holding this satellite chain tight against stop is taken off, elevator conveys empty satellite to lower chain 16. Mechanism 4 displaces both satellite chain through one step equal to satellite length. Then elevator 28 moves satellite from lower chain to upper one at loading position, and the entire cycle is resumed. Upon taking all components out horizontal channels of magazines in one rod of mechanisms 8, units 10 of changeable magazines go up through one step equal to distance between channels in vertical plane, and the entire cycle is resumed. Upon taking all components out of all rows, empty magazines 9 are replaced by filled ones, and units 10 of changeable magazines are moved down by mechanism 8 until channels of first horizontal row in all magazines are aligned with channels in units 11 of printed-circuit board wiring. EFFECT: facilitated mounting of components on printed-circuit boards. 8 cl, 9 dwg, 1 tbl

Abstract: FIELD: computer engineering, compression of pictures. SUBSTANCE: method involves sampling of input signals in M-radix alphabet into two levels using context model of input data. Specific two-level sampling is selected from hash table which maps each input character into set of binary values. Mapping is defined by means of analysis of compressed messages and is transmitted together with compressed images as addition. Mapping serves as local minimum of bit entropy of two- level sampling. If hash table is used or not for input characters, they can be converted to compressed ones in parallel for bits of input characters. Buffer and sorting operations are performed when it is necessary to use bits for context of decoded bit before expander decodes decoded bit. Expander has unit which performs reverse ordering. This results in fact that output of expander is equal to input of compressing unit. EFFECT: increased compression rate.
