Inventor: STEAD WILLIAM JOHN
IPC: C10L5/26
Filed: 1989-03-30
Abstract: In a process for making fuel briquettes from powdered anthracite and using molasses as a binder, "Green" briquettes have their moisture contact reduced or are dried prior to their admission to a first oven for a relatively short stay to initiate curing. The drying or moisture reduction step improves Green strength and reduces losses in the first oven. Curing develops during a "holding" step with no further heat input prior to admission to a second oven to complete curing. The process achieves an improved yield with greater economy particularly in terms of heating costs.

Title: Diffusion bonding of aluminium-lithium alloys
Inventor: DUNFORD DAVID VICTOR
IPC: B23K20/233
Filed: 1990-03-16
Abstract: Pieces of aluminium-lithium alloy including reinforced composites thereof are diffusion bonded without prior surface coating by a process comprising initial mechanical removal of surface oxide and lithium depleted material, smoothing the faying surfaces, placing the pieces whilst space apart into a vacuum chamber, evacuating same, pressing the faying surfaces heavily together, raising their temperature whilst decreasing the applied pressure, and holding the pieces for at least one hour at a temperature in the range 500 to 580 DEG C whilst under light contact pressure. The freedom of movement of lithium within the joint pieces and its ability to disrupt the reoxidised surface layer circumvents any necessity for prevention of reoxidisation when a suitable diffusion bonding regime is utilised for the bonding process. <IMAGE>

Title: Method of and apparatus for condensing vaporous substances
Inventor: HEBELS ALBERT
IPC: F26B25/00
Filed: 1991-03-21
Abstract: A running web the upper side of which is coated with one or more films containing a volatile substance is heated from below in a housing which contains a driven cooled condensing roller in the space above the path for the web. The vaporous substance which is expelled as a result of heating of the web is condensed on the peripheral surface of the cooled roller, and the film of condensate is stripped off the peripheral surface to enter an evacuating trough. The rate of condensation can be regulated by changing the rotational speed of the roller in dependency upon variations of pressure of vaporous substance above the running web and/or in dependency on the monitored rate of escape of vaporous substance into the atmosphere. Alternatively, or in addition to regulation of condensation in response to signals from pressure- and/or flow rate monitoring sensors, the rate of condensation can be adjusted by altering the cooling action upon the roller in dependency on fluctuations of pressure in the housing and/or in dependency on the rate of flow of vaporous substance into the atmosphere.
