PATENTS System for rapid pressurisation of a motor compartment Applicant: Dresser-Rand Co, USA This patent describes a system for the rapid pressurisation of a motor compartment and cooling system during a shutdown, a surge, and/or other situations in which the suction pressure varies significantly. The motor–compressor arrangement includes a seal-gas system that is connected to the motor compartment via a pressurisation line – with the outlet of the compressor and shaft seal. A valve is coupled to the motor pressurisation line and a controller is configured to open this valve at start-up of the motor-compressor to supply seal gas to the motor compartment, and to pressurise it when the difference between the seal-gas supply pressure and the suction pressure is indicative of the seal-gas supply pressure being insufficient.

Multi-layer gasket Applicant: Reinz-Dichtungs GmbH, Germany This invention relates to a multi-layer gasket, but in particular to a multi-layer gasket with two or more metallic layers. Such gaskets are used, for example, in the exhaust line of an internal combustion engine and also in a fuel cell. Patent number: WO/2012/055550 Inventors: K. Höhe, G. Egloff, H. Waldvogel and W. Krautmann Publication date: 3 May 2012
Seal packing Applicants: Commissariat à l’Énergie Atomique et aux Énergies Alternatives and Echnetics Group France Sas – France In this invention, the compression between two blocks (5 & 6), establishing a dynamic seal (13) between a rotor (2) and a stator (1), is provided by an inflatable seal (7) housed in a groove. When the blocks are intended to be sectile – that is to say, divided into two parts in order to be assembled around the shaft (2) – the seal (7), which at first is linear, is wound around in the groove with its ends joined up. This seal provides uniform compression around the circumference and no longer requires any significant disassembly of the apparatus, in which it used, in order to be placed.

Connector assembly for a vehicle’s electrical power supply Applicant: FCI Automotive Holding, France This patent provides details of a connector housing, in particular, for a vehicle’s electrical power supply. It also discusses methods of manufacturing this housing. An objective of this invention is to provide a safer sealing system that prevents the seal from being damaged or the connector mating operation from being blocked. Patent number: WO/2012/056274 Inventors: J. Fabre, G. Schmitt and F. Menez Publication date: 3 May 2012
Applicant: Metal One Corp, Japan Details of a screw connector for an oil-well pipe are provided by this patent. The connector is equipped with a male screw that has a seal formed as a convex surface and a shoulder formed farther towards the tip than the seal. The female screw has a tapered seal, with the contact portion of the seal of the male screw and the seal of the female screw being formed by pressure bonding. The length of the male screw, from its tip to the contact portion, parallel to the longitudinal direction of the male screw, is set according to the thickness of the oil-well pipe. Patent number: WO/2012/056500 Inventor: T. Suzuki Publication date: 3 May 2012
Shaft seal Applicant: Mitsubishi Heavy Industries Ltd, Japan Details are provided of a design for shaft seal. According to this patent, even if the seal of the shaft seal structure of a rotating body is inclined, the design can prevent the seal from being held in an inclined posture. Referring to the accompanying figure, an accommodation body (9) is disposed in a stator, and the seal body (12) comprises a plurality of thin, plate seal pieces (20) stacked in the circumferential
Fuel-cell assembly sealing arrangement Applicant: UTC Power Corp, USA The subject of this patent is an assembly that includes a seal which is configured to be placed between a fuel-cell manifold and a fuel-cell stack. This seal contains a recessed area in its side that faces the fuel-cell stack. The assembly also includes a second seal that is configured to be placed between the first seal and the fuel-cell stack, within the recessed area. An example of the method of sealing the fuel-cell interface involves holding the first seal within a groove (established within a manifold) and holding the second seal within the recessed area established within the second
The design detailed by patent WO/2012/057204 prevents a seal body from being held in an inclined posture.
