Patent CA-2707852-A1 (CA)
Inventor: FOLSBERG JAN
IPC: B02C15/14
Filed: 2008-09-25
Abstract: Described is a roller mill (1) for grinding particulate material such as cement raw materials, cement clinker and the like, said roller mill (1) comprising a grinding table (3), a set of rollers rotatable about a vertical shaft (5), said set of rollers comprising a number of rollers (4) rotating about separate roller shafts (6), which are connected to the vertical shaft (5), and a nozzle ring (7) for directing gases into the roller mill (1), said nozzle ring (7) enclosing the grinding table (3), and means (8) for regu-lating the gas flow through the nozzle ring (7).  The roller mil is peculiar in that at least some of the regulation means (8) are arranged to ro-tate together with the set of rollers. In order to ensure optimum regulation of the gas flow through the nozzle ring in relation to the uneven load imposed by the material, thereby optimiz-ing the roller mill operation in terms of capac-ity, grinding efficiency and energy consump-tion, the position of at least some of the regula-tion means for regulating the gas flow through the nozzle ring relative to the set of rollers re-mains the same at all times. The gases which are introduced into the mill via the nozzle ring will, therefore, always exhibit the same flow pattern in relation to the set of rollers.

Title: Heat pump water heater and associated control system
Inventor: KLEMAN KELVIN W
IPC: F24H4/04
Filed: 2010-07-06
Abstract: A heat pump water heater has a tank portion, an electric heating structure for adding electrical heat to water stored in the tank, and a heat pump for adding refrigerant heat to the tank water. A control system associated with the water heater has three user-selectable heating modes for heating the tank water during a given heating demand cycle - a first mode that initially heats the tank water with refrigerant heat while the electric heat is locked out for a first predetermined period before supplementing the refrigerant heat if necessary, a second mode similar to the first mode but with a longer electric heat lockout period, and a third mode in which only the electric heat is utilized to satisfy a tank water heating demand. Illustratively, the heat pump is disposed in a compact component arrangement on the top end of the water heater tank.

Title: Method for sorptive extraction of precious metals
Inventor: LOGVINENKO IZABELLA ALEKSEEVNA
IPC: C22B3/10
Filed: 2009-09-08
Abstract: The method for sorptive extraction of precious metals from mineral raw materials containing alkaline and alkaline earth metal chlorides relates to hydrometallurgy and can be used for extracting precious metals (palladium, platinum, gold and silver) from different types of raw mineral materials. It includes sorption of precious metals from a pulp using a synthetic sorbent that contains strong and weak base functional groups, followed by desorption.  Sorbent is washed in two stages with the liquid phase of the waste pulp and water, and then precious metals are desorbed using a hydrochloric acid solution of thiourea.  Precious metals are precipitated from the thiourea solution into a collective concentrate using an ammonium hydroxide solution. The process is carried out in a cascade of six devices with screen drainages with a fixed volume of sorbent load in each device. Precious metals are desorbed at 50-60°C using a solution containing thiourea and hydrochloric acid.
