Patent EP-0460312-A1 (EP)
Inventor: HAY ALLAN
IPC: B60P1/34
Filed: 1990-06-06
Abstract: A trailer 1 has a chassis 10 supported on road wheels 12 and having a flat load platform 20 connected thereto by a pivot arrangement 22 at the rear of the chassis. A hydraulic ram 26 is connected between the chassis 10 and the platform 20. The pivot arrangement 22 comprises, at each side of the trailer 1, a plate 28 secured to and depending from the platform 20. A slot 30 in the plate 28 is engaged by a pin 32 projecting from the chassis 10. Initial extension of the ram causes the platform 20 to move rearwardly and upwardly in a path dictated by the pins 32 moving in the slots 30, thus raising the rear of the platform 20. Continued operation of the ram 26 then causes the platform 20 to pivot about the pins 32, thus raising the front of the platform 20.

Abstract: A packer (26) for use with a ram-type blowout preventer which has the capacity to accommodate a plurality of sizes of tubular members extending through the bore of the blowout preventer. The packer has a resilient body (28) designed to fit the face recess of the ram and a central recess (30) to receive a tubular member, an upper plate (32) positioned in the upper portion of the resilient body, a lower plate (34) positioned in the lower portion of the resilient body, and a plurality of metal insert segments (36, 38) positioned between the upper surface of the resilient body and the under surface of the upper plate and around the central recess of the resilient body. The metal insert segments have sufficient length to engage the exterior of a tubular member which is to be engaged and sealed against by the resilient body with the insert segments being selected to seal against a preselected small tubular member diameter which is less than the diameter which could be sealed by the packer without the insert segments. The resilient body is provided with a relief area around its central recess immediately above the lower plate. In another form a second set of insert segments are provided to extend to a smaller diameter than the first set of insert segements.

Title: Condensation of metal vapours in a fluidized bed.
Inventor: PLAYER ROGER LEO
IPC: B01D5/00
Filed: 1990-11-07
Abstract: Metal vapour, for example zinc fume in the offgas of a smelting furnace, is captured by bringing the stream into direct contact with a fluidized bed of solid particles having a particulate loading of greater than 10 kg/m<3> and preferably greater than 400 kg/m<3>. The thermal mass and temperature of the bed is such as to rapidly quench the vapour in the case of zinc from above 960  DEG C to below 419 DEG C in less than 100 milliseconds, whereby the vapour condenses in the bed and is recovered as zinc metal in acceptable yield.
