A case includes a case body, a lid, hinges supporting the lid on the case body and a waterproof seal placed on the joining surface of the case body. The lid can be turned for closing on the hinges so as to compress the waterproof seal perpendicularly to the joining surface of the case body. Each hinge is provided with a hinge pin having opposite cylindrical end parts and an offset middle part defining a groove together with the cylindrical end parts. The grooves of the hinges permit first knuckles formed integrally with the lid to sink therein so that the lid held with its joining surface parallel to the joining surface of the case body can be moved toward the case body perpendicularly to the joining surface of the case body to compress the waterproof seal perpendicularly between the joining surfaces of the lid and the case body. The hinge pin is restrained from coming off by the first knuckles when the first knuckles are engaged in the groove.

A sealing structure for sealing a gap between a combustor liner having an outer surface and a surrounding structure surrounding the combustor liner, includes: an annular sealing member held on the surrounding structure so as to be in contact with the outer surface of the combustor liner. The sealing member includes a plurality of sealing segments arranged in an annular configuration. The sealing structure seals the gap around the combustor liner of the combustor and absorbs, the difference in thermal expansion between the combustor liner and the surrounding structure.

A connector (10) for flexible pipes, particularly for use in cooling or air-conditioning systems for motor vehicles, comprises a hollow main body including a coupling element (13) for a flexible pipe, the coupling element having at least one gripping tooth (16a, 16b) for cooperating with clamping means (6) to grip a flexible pipe (14) when the connector is in the condition of use. The connector comprises at least one sealing ring (17) having a substantially cylindrical inside wall (18) and a shaped, preferably arcuate, outside wall (19). The sealing ring (17) exhibits resilient behaviour in a radial direction and is compressed radially, when the connector (10) is in the condition of use, by the flexible pipe (14) which is fitted and clamped on the coupling element (13) by the clamping means (6).

The invention relates to a sealing arrangement for sealing and guiding a powered window pane (40), particularly of a motor vehicle. Said sealing arrangement is provided with a seal (20) produced as a single part from an elastically deformable material. The inventive sealing arrangement is also provided with a sash (10) which frames the window pane (40) and to which the seal (20) can be fixed. Said sash (10) comprises an inner flange (11) and an outer flange (12). The seal (20) comprises an inner side section (21) that can be fixed to the inner flange (11), an outer side section (22) that can be fixed to the outer flange (12), and a base portion (23) located outside the cavity portion (13). The aim of the invention is to achieve a universal embodiment of the seal (20). To this end, an inner sealing element (25) arranged on the inner leg portion (21), and an outer sealing element (26) arranged on the outer leg portion (22), are respectively embodied as a hollow chamber and provided with a contact surface area (29, 30) that can be applied to a side surface (41, 42) of the window pane (40). Said contact surface areas (29, 30) are embodied in two directions (x, y) extending perpendicularly in relation to each other, in such a way that the window pane (40) can be reversibly displaced between the inner sealing element (25) an the outer sealing element (26).

An ear cup for a hearing protection unit including an inner cup portion which defines a noise damping space facing towards the user. The ear cup further has an outer cup portion for accommodating electronics and / or a current source. The inner cup portion and the outer cup portion are separated by a partition which is of one piece manufacture with the inner cup portion. The partition is substantially closed, with the exception of an opening in which a fixing portion on a bracket is disposed. The fixing portion (9) has a central channel (15) for the passage of supply conductors to a loudspeaker. The supply conductors have a contact placed on the outside of the partition for connection of the electronics. The bracket also has a baffle plate which extends along the periphery of the loudspeaker.

A piston for a fluid operated power cylinder has two mutually coaxial sealing lips axially extending away from each other and being able to radially yield, for sealing engagement with the piston running face of the power cylinder and adjacent to at least one piston end side an elastic buffer body serving for shock absorbing in the end of stroke position of the piston, said body having an impact face facing away from the piston. At least at one piston end face the sealing lip itself constitutes the buffer body and has the impact face at its end, groove-like recesses being formed on the inner periphery of the sealing lip with a distribution in the peripheral direction, such recesses opening toward said impact face.

Extraction system for preparing a beverage from a cartridge using a fluid injected under pressure into the cartridge. The system includes a cartridge and an extraction device intended to accept the cartridge. The extraction device includes an injection cage and a cartridge support being arranged in such a way as to be moved relative to one another in the pre-injection mode of closure around the cartridge by a closure device. The injection cage has a base and a closure piston unit which is mounted such that it can be moved axially with respect to the base. The closure piston unit can be moved relative to the base by the pressure exerted by the fluid upon injection.
