Method for manufacturing a composite ring, composite ring, use of the ring in a seal assembly and seal assembly

A plastic pressure vessel comprises a first () and a second part () welded to each other. The first part () comprises a layer () of thermoplastic material having substantially continuous fibres. The second part comprises a layered structure having an first () and a second () layer of thermoplastic material having substantially continuous fibres separated by a central () layer comprising thermoplastic material. The layer having substantially continuous fibres () of the first part extends over a length (d) sandwiched in between and connected with the first () and second () layer of thermoplastic material having substantial continuous fibres of the second part. Preferably the second part is provided with a slit () and the first part with a fitting protrusion, preferably with a bevelled end ().

Plastic pressure vessel for a fluid and method of manufacturing such a vessel

A method for thermally processing a sheet of a thermographic material provides good flatness and dimensional stability together with a high optical homogeneity. The method incorporates the steps of supplying a sheet of thermographic material m ( ) to a thermal processor ( ) having a processing chamber ( ), heating the processing chamber to a predetermined processing temperature, and transporting the sheet of thermographic material through the processing chamber in a sinuous way ( ). This transporting is carried out by a first drivable belt ( ), a second drivable belt ( ) and backing means ( ).

Thermal processing of a sheet of thermographic material

The apparatus comprises at least one treatment vessel (12) comprising a housing (14) having a sheet material inlet opening (17) and a sheet material outlet opening (18) defining a sheet material path (20) through said vessel (12). Each opening (17, 18) is closed by a path-defining rotatable roller (28) biased towards a reaction surface (30) to form a nip (36) there-between through which said sheet material path (20) extends. The path-defining roller (28) is in contact along its length, with a plurality of rotatable intermediate rollers (38) carried in fixed bearings (40) mounted on said housing (14).

Apparatus for the wet processing of photographic sheet material

The roller comprises a core (56) having an elastomeric covering which comprises an outer exposed region (60) and an intermediate region (58) positioned between the outer region (60) and the core (56). The outer region (60) has a thickness which decreases towards each end of the roller and the intermediate region (58) has a thickness which increases towards each end of the roller. When associated with another such roller to form a nip in an apparatus for wet processing sheet materials, carry-over is reduced, leakage when no sheet material is passing through the nip is reduced, and the risk of physical damage to the sheet material is reduced.

Roller for use in wet processing apparatus

A roller, for use in a photographic sheet material processing apparatus, comprises a core (32) provided with a covering of relatively soft material (34). The roller has a length (L) of from 0.4 to 2.0 m. The core has a maximum diameter (D) of less than 0.04*L m. The roller is characterised by having a deflection as measured by a specific test and a weight (W) below levels defined by a specified boundary condition formulae (1) & (2). Rollers satisfying this condition are characterised in that the core is formed of a composite material comprising fibers and a resin matrix. Such rollers have a relatively small diameter, are light and yet still have sufficient stiffness to avoid substantial wrinkling of the sheet material in the apparatus and to satisfy the requirements of high processing quality.
