Title: Preparing a catalyst containing a group viii metal and a non-acidic promoter dispersed on a support via simultaneous impregnation
Inventor: BRICKER MAUREEN L
IPC: B01J37/24
Filed: 1996-01-03
Abstract: Catalysts containing a Group VIII metal and a non-acidic promoter are prepared by simultaneous impregnation using a first aqueous solution of a chelating ligand such as ethylenediaminetetraacetic acid and a promoter metal salt which is prepared and heated to a temperature of 80°C to its boiling point and then combined with a second aqueous solution containing a Group VIII metal compound. This mixed solution is aged at a temperature of 40 to 100°C and then used to impregnate a support, e.g., alumina spheres. The impregnated support is then dried, calcined and reduced with hydrogen. Prior to reduction the catalyst may optionally be treated with a chlorine or chloride stream.

Title: Cylinder Assembly for a Reciprocating Compressor
Inventor: KIM JU HWAN
IPC: F04B39/00
Filed: 1996-07-23
Abstract: A cylinder assembly for a reciprocating compressor has a piston comprising a first piston member connected to a connecting rod; a second piston member provided with a piston head and connected to the first piston member in such a way as to move relatively to the first piston member for a predetermined length in the axial direction; and a elastically deformable member in the form of a spring washer interposed between the distal end face of the first piston member and a corresponding face of the second piston member to urge the first piston member and the second piston member apart from each other. Accordingly, the amount of the residual refrigerant is minimized to decrease re-expansion of the residual refrigerant and increase the amount of the sucked refrigerant, and consequently to improve the compressor efficiency. At the same time, the risk of damage to the suction valve plate and reed by the high-pressure refrigerant and oil-refrigerant mixture can be reduced.
