Title: Exhaust gas purifying device for engines
Inventor: HORI YOSHIAKI
IPC: F01L3/20
Filed: 2004-02-12
Abstract: If a camshaft is disposed in the longitudinal direction of a vehicle body, an exhaust port is defined in the front surface of an engine, and a coolant pipe is disposed from a radiator in front of the engine to the front surface of the engine, then no space is available near the exhaust port for installing a valve case. It is an object of the present invention to install a valve case with ease. An engine 5 is disposed with a crankshaft 6 axially oriented i n the longitudinal direction of the vehicle body. A camshaft and an exhaust port in a cylinder head 11 are disposed parallel to the crankshaft 6. The exhaust port is open at the front surface of the cylinder head 11, and discharges exhaust gases through an exhaust pipe 13. Hoses 19, 21 extend from a radiator 20 in front of the engine 5 to the front surface of the engine 5. A valve case 14 is disposed on a left side of a cylinder block 10 in the vicinity of the exhaust port to which the exhaust pipe 13 is connected, and is connected to an air cleaner 15 behind the engine 5 by a substantially straight secondary air pipe 16.

Abstract: A modular conveyor belt (10) forming a hinge between consecutive belt rows hingedly connected by a rolling hinge pin pair (34). Hinge eyes (28) along the forward and rearward ends of each row of belt modules include aligned openings (30) for the hinge pins. The belt rows are arranged end-to-end with the hinge eyes of adjacent rows interleaved. The hinge pin pairs (34) are inserted side by side in the passageway formed by the aligned openings (30) of the interleaved hinge eyes (28). The hinge pin pairs include first and second hinge pins (40, 41) having outer contact surfaces. The openings in the hinge eyes are characterized by a narrow end (32) with constraining surfaces for positioning the first hinge pin and flaring out to a wider second end (33) bounded by a roll surface that gives the second hinge pin clearance to roll along the roll surface as the belt articulates. During belt articulation, each hinge pin of the pair rolls against the other and along the roll surfaces instead of sliding against the walls of the openings.

Title: Zinc recovery process
Inventor: HOULLIS FRANK
IPC: C22B3/12
Filed: 2002-09-12
Abstract: A process for the recovery of zinc metal from a zinc mineral includes the steps of leaching the zinc mineral in a solution including a halide species formed from two or more different halides, to leach the zinc into the solution. The zinc-bearing solution is then electrolysed to yield zinc metal and to generate the halide species. The electrolysed solution including the halide species is then returned to the leaching step. A portion of the electrolysed solution can be removed as a bleed stream from a cathode compartment of an electrolytic cell of the electrolysis process and processe d to remove manganese as manganese dioxide precipitate by adding thereto limestone, and the halide species from an anode compartment of the electrolysis process. In this regard, the pH and Eh of the solution can regulated in a manner that favours the formation of the manganese dioxide precipitate over the formation of a precipitate of zinc.

Patent CA-2476397-A1 (CA)
Inventor: SILIGARDI GIULIANO
IPC: A61K47/48
Filed: 2002-02-15
Abstract: An exogenous pharmaceutical preparation in which a lipid tagged bioactive material is combined with albumin is disclosed. The albumin has a low proportion of lipidic/fatty acid groups (a molar ratio of fatty acid groups to albumin of less than 0.7) and is preferably fatty acid free. The albumin may be naturally extracted such as Human Serum Albumin or recombinantly produced.  A range of bioactive substances, such as peptides, proteins or vaccines may be tagged and combined with albumin for human, veterinary or agricultural use.  Several antimicrobial peptides are disclosed. Binding to the albumin mediates the biostability of the tagged bioactive material. Due to this stabilisation, the antimicrobial activity of a model lipopeptide is enhanced when combined with substantially fatty acid free-albumin. When bound to albumin, therefore, the model lipopeptide exerts an antimicrobial effect at a lower concentration than the model lipopeptide alone.
