Title: Method and apparatus for reducing the energy consumption when drying a paper web
Inventor: TELL LARS ERIK KARL AXEL
IPC: D21F7/00
Filed: 1984-05-19
Granted: 1988-12-08
Abstract: A paper web (1) of low grammage is formed on a fabric (3) in the wet end of a paper machine, picked up from the fabric (3) by pick-up means (9, 11), and after the picking-up is conveyed to and through the drying section (13, 15) of the paper machine. To reduce the energy consumption for the drying in the drying section the web (1) is divided by means of edge cutters (25) into a trimmed web (1a) and couch trimmings (1b) while it is being conveyed on the fabric (3). Thereafter the trimmings (1b) are retained on the fabric (3) by means of suction means (27) when the trimmed web (1a) is picked up from the fabric (3) to be conveyed to and through the drying section (13, 15), and finally the retained trimmings (1b) are removed from the fabric (3) by means of a wire roll (41) located externally of the fabric loop. Said suction means comprise a suction box (27) having a suction slot (31) of a length that substantially corresponds to the width of the couch trimmings (1b), and the suction box (27) is located some few millimetres (A) below the plane (39) of the fabric (3) and is able to develop a suction force that is sufficient to displace the fabric edge portion, which carries the couch trimmings (1b), from the plane (39) of the fabric in the area of the picking-up of the trimmed web (1a) from the fabric (3). Hereby you avoid on one hand web breaks and similar problems, and on the other hand that the couch trimmings (1b) are picked up from the fabric (3) together with the trimmed web (1a).

Title: Improved method and apparatus for cleaning reusable containers
Inventor: COOMBS JOHN ANTHONY
IPC: B08B3/12
Filed: 1984-04-13
Granted: 1989-11-09
Abstract: An apparatus for cleansing objects by passage through a tank containing a detergent liquor, which is subjected to ultrasonic vibration is provided with sprayers for rinsing the articles emerging from the detergent liquor by liquid drawn from the detergent bath. In order to control the build up of solids in the detergent bath, the liquor supplied to the sprayers is filtered through a moving filter band, from which the accumulated solids are removed by spraying wash liquor onto the reverse surface of the filter band. The filter band is mounted on a frame, which is supported by a pivot at one end and incorporates a suction box into which filtered liquid is drawn through the filter band. The filter band rests upon a support roller or the like. The weight of the frame tensions the belt. When the frmae and band are lifted out, the band is loose on the frame and may be replace very simply. The band may be driven by the external support roller or through a drive roller in contact with the reverse face of the band.

Abstract: @ (6R)-Tetrahydro-L-biopterin of the following formula:is prepared by catalytically reducing L-erythro-biopterin or an acyl derivative thereof in the presence of an amine, at pH 10 - 13 and with a platinum-base catalyst and when one or more acyl groups still remain, then removing the acyl groups. (6R)-Tetrahydro-L-biopterin is effective for the treatment of certain serious neuroses and malignant hyperphenylalaniemia. The present invention has succeeded in preparing (6R)-tetrahydro-L-biopterin at a high asymmetric ratio R/S and moreover with a high yield. Since the process of this invention makes use of an amine as a base, the process is free from admixture of any inorganic salt and can hence provide high-purity crystals with ease.
