Abstract: Apparatus and method in converting municipal solid waste into geo-polymer briquettes and geo-polymer bricks comprising bag opener cum crushers, magnetic separators for ferrous and eddy current separators for non-ferrous things; squeezer for removing liquid content; inter particle collision driers for drying; pulverizer for pulverizing, and devolatizing carbonization reactor for carbonisation of combustible MSW to produce solid char with low water content. Solid char is mixed with geo- polymer binding agent/starch/tar/ to form combustible pellet/briquette. These highly combustible briquette/pellets have high calorific value. The pellet/briquette is formed by rotating combustible char at high rpm and compaction. Pellet has a water content of less than 5% by weight and fuel value of 5500 to 6500 KCAL This process produces non-combustible geo-polymer brick. The non-combustible MSW separated by a trommel is crushed by inter particle collision crusher and pan mixers mixing with geo-polymer binding agent/fly ash/quarry dust/chips or china clay and moulded.

Title: N+0 redundancy in a network access system
Inventor: KRAPP STEVEN JOHN
IPC: H04L12/28
Filed: 2016-08-16
Abstract: Particular embodiments provide an N+0 sharing scheme for networks. The N+0 sharing scheme includes no dedicated spare among a group of active elements. Each active element may provide service to a medium, which may be associated with a medium.  When a failure to one of the active elements occurs, at least one of the working active elements takes the workload of the failed active element. The cost of N+0 sharing is a reduced per medium (e.g., service group) capacity during a failure. That is, some service groups may receive less bandwidth from the active element that is used in the sharing scheme to compensate for the failure. However, this may be preferable to service operators compared to the additional cost of including a spare for the group of active elements, or the complete loss of service that occurs when a failure occurs without a failure recovery scheme.

Patent CA-3000216-A1 (CA)
Inventor: LIU JUNQIANG
IPC: B01D53/04
Filed: 2016-09-08
Abstract: A process to prepare a carbon molecular sieve adsorbent composition comprises steps beginning with an activated carbon having specific effective micropore size. The activated carbon is impregnated with monomers or partially polymerized polymer, allowed to complete polymerization, and then carbonized such that the impregnant shrinks the micropores to another specific effective micropore size. Finally, the impregnated/polymerized/carbonized product is annealed at a temperature ranging from 1000 °C to 1500 °C, which ultimately and predictably shrinks the micropores to a size ranging from 4.0 Angstroms to 4.3 Angstroms. The invention surprisingly enables fine tuning of the effective micropore size, as well as desirable selectivity, capacity and adsorption rates, to obtain highly desirable carbon molecular sieving capability particularly suited for use in, for example, fixed beds in pressure swing or temperature swing processes to enable propylene/propane separations.
