Abstract: 642,841. Platen presses. VICKERS-ARMSTRONGS, Ltd. March 4, 1948, No. 6794. [Class 100 (ii)] The platen 1 of a press is moved towards the bed 2 by means of a crank-operated rod 6 which imparts to the platen a combined rotational and translatory motion followed by a final purely translatory motion perpendicular to the bed. The mechanism controlling the motion is constructed so that the control takes place by surface contact, and the control comprises links 10 provided with slots in which can slide a block 12 in the pivot 11 of the links when the final translatory motion takes place. As the platen closes a curved surface 4 integral therewith engages a guide surface 3 fixed on the machine frame and arranged normal to the bed 2, and finally a flat surface 5 engages and slides over the surface 3. During this final movement the block 12 slides relatively to the links 10 and permits of elimination of the rotational motion. Subsidiary supports 17 co-operate with the surfaces 3 to counteract unbalanced forces due to the impact of the platen.

Title: A method of preventing overheating of the adsorbent in the recovery of easily decomposing solvents
IPC: B01D53/04
Filed: 1963-02-25
Abstract: Oxidizable solvent vapours are removed from exhaust air by adsorption on active charcoal and the charcoal is prevented from overheating by charging it with a substance which boils at a higher temperature than the recovered solvent, the amount of higher boiling substance present in the charcoal being at least weight 10% of the adsorbed solvent at any given time.  The higher boiling substance may be benzene, toluene, a hydrocarbon fraction, an alcohol or an ester e.g. butyl acetate.  The higher boiling substance may be introduced by spraying it into the stream of exhaust air flowing to the adsorber or saturating a branch stream thereof by spraying or by contacting the air stream with the substance and then recombining it with the main stream.  Another method of introduction consists of saturating fresh air used for cooling the desorbed charcoal with the higher boiling substance either in the main stream or in a branch stream.  The charcoal may be desorbed using steam.  Particular reference is made to exhaust air containing acetone, ethyl methyl ketone, ethanol and propanol wherein toluene and/or water vapour are used as the higher boiling substances.
