Production of gasket material
PATENTS
Patents Seal structure for fuel cell, and method for its production
Process for producing metallic gasket
Applicant: NOK Corporation, Japan
This patent describes the screen printing of liquid elastomer onto the beads of a metallic gasket such as a cylinder head gasket. The screen printing contributes to
A seal structure for impregnating the outer circumference of a gas diffusion layer with a rubber seal is described. The method permits the moulding of an effective seal while
retaining the maximum area for the membrane electrode assembly. Patent number: WO 2007/010632 Inventor: T. Okabe Publication date: 25 January 2007
Applicants: NOK Corporation and Ishino Gasket Mfg Co Ltd, Japan achieving an even thickness after curing. Patent number: WO 2007/010914 Inventors: H. Nikamoto et al. Publication date: 25 January 2007
Gasket for refrigerator door Mechanical seal
Applicant: LG Electronics Inc, Korea
Applicant: Eagle Industry Co Ltd, Japan
A gasket for a refrigerator door is described that includes an insulating foam in the hollow section of the gasket. The gasket hence provides some additional insulation as
This patent describes an elastomer bellows type mechanical seal that is designed to provide improved location and retention of the stationary seal face and a more positive location of the bellows. The stationary face is retained and sealed by an elastomer coated sleeve, similar to the stationary
OD seal of a rotary shaft lip seal. The retaining band that clamps the bellows to the shaft is connected to an outer sleeve that has a retaining lip over the front edge of the rotating seal face. Patent number: WO 2007/010761 Inventor: Y. Takigahira Publication date: 25 January 2007
well as sealing the door. A number of potential materials are listed. Patent number: WO 2007/011124 Inventor: Y.-W. Kim Publication date: 25 January 2007
Watertight seal installation device Applicant: Shinmaywa Industries Ltd, Japan This production assembly system can be used to install watertight seals on electric cables.
Patent number: WO 2007/013243 Inventor: S. Sakaue Publication date: 1 February 2007
Hydrodynamic seal with contact pressure control, anti-rotation and filler retention Applicant: Kalsi Engineering Inc, USA This patent describes a modified version of the hydrodynamic seal manufactured by the applicant. This version is particularly intended for applications where the external environment may be at a higher pressure than the lubricant. An energizing insert is fitted into a recess in the low environment side of the seal and
anti rotation pins moulded into the rear face of the seal on the lubricant side. The seal is inhibited from rotating within the groove or distorting and allowing ingress of contaminant. Patent number: WO 2007/011883 Inventors: J.E. Schroeder, J.D. Gobeli and L.L. Dietle Publication date: 25 January 2007
The elastomer bellows mechanical seal described in 2007/010761.
Production of gasket material Applicant: Bridgestone Corporation, Japan A sealing material is described which comprises (A), an unsaturated group-containing ester-type urethane oligomer, which is an energy ray-curable liquid resin, and (B) a compound having at least one carbodiimide group in the molecule. B is used in the proportions 0.10 to 10 parts to 100 parts of A, by mass. Among the 14
benefits claimed for this material are: good moist heat durability, precise extrusions and good long term storage. It is also said to have low adhesion which is beneficial for re-use. Patent number: WO 2007/011029 Inventors: T. Hiraiwa, N. Ohmori and T. Kurata Publication date: 25 January 2007
Patent WO 2007/011883 describes a modified Kalsi seal with energizer insert and anti-rotation pins.
