Title: Process for conducting chemical equilibrium reactions
Inventor: SCHEFFER BOB
IPC: B01J23/80
Filed: 1991-05-08
Abstract: The invention provides a process for conducting chemical equilibrium reactions involving gaseous reactants which yield a liquid product using a plurality of fluidised bed catalytic reactors in series and an inert solvent to absorb the reaction product from the reaction mixture. Between at least two consecutive fluidized bed reactors, R1, R2, R3, there are means S1, S2, S3 effecting intimate contact between the inert solvent and the product-containing reaction mixture, which also comprises a means effecting a separation of a liquid reaction product/inert solvent solution and a gaseous phase which passes to the next fluidised bed reactor. Preferably this is a swirl tube. Preferably the process is used to prepare methanol by reaction of a gaseous mixture comprising hydrogen and carbon monoxide. The inert solvent employed may be e.g. water, a higher alcohol, a higher ether or a higher ester. The catalyst composition in the bed may comprise the elements copper and zinc and is optionally promoted with another element. The operating conditions of the reactors are within the temperature range of 100 to 350 DEG C and the pressure within the range from 3 to 35 MPa. The invention also provides an apparatus suitable for carrying out the above process. <IMAGE>

Title: Roll forming machine
Inventor: CADNEY STEPHEN
IPC: B21D5/08
Filed: 1992-12-11
Abstract: A roll forming machine is used for forming material, typically metal strip into various shapes. The machines comprise pairs of forming rolls (39, 40) which are spaced apart along an axis. The profile of the roll pairs progressively change along the axis, so that respective pairs of rolls effect different degrees of folding to material passing between them. As a result, the machine is capable of effecting progressive folding of material fed between the pairs of rolls along this axis. In the present machines, versatility of the machines is improved by using forming rolls (30, 35) each comprising a plurality of roll section elements (1, 2, 3). The roll section elements are mounted so as to be independently freely revolvable about the axis of the roll (30, 35) and additionally they may be driven so that they are capable of assisting both in folding/forming roll material (19) and in transmitting drive thereto. The roll elements (1, 2) are mounted such that they may be moved aside and up and down into various positions for the purpose of altering the forming roll profile (30) and so altering the profile of the formed end product, without the need to replace the roll elements with others of a different shape. <IMAGE>

Patent GB-2272966-A (GB)
Title: Refrigerating walls
Inventor: VATAVUK NENAD
IPC: F25D31/00
Filed: 1993-11-25
Abstract: Refrigeration of a container is effected by a refrigerating wall having a surface (18) in contact with the contents of the container. Within the wall a number of cooling tubes (10) extend, part of the peripheral surface of each said cooling tube (10) being defined by the cooling surface (18). Refrigerant liquid from a supply is fed by way of a feed tube (14) to a transversely extending distribution tube (13) which is above and in communication with the cooling tubes (10). Thus, refrigerant falls under gravity through the cooling tubes (10). The continual flow of refrigerant liquid prevents the build-up of vapour adjacent the refrigerating surface. To enable different zones to be selectively cooled, one or more secondary distribution systems are provided. The secondary system has a secondary distribution tube (15) arranged above and in communication with a number of auxiliary tubes (16) which are shorter than the cooling tubes (10). If the supply of refrigerant to the main distribution tube (13) is prevented by operation of a valve (20b) in the feed tube (14), fluid from the secondary distribution tube (15) will flow within the lower parts of the tubes (10) to provide cooling of the lower zone (21) only. <IMAGE>
