Title: Rinsing cutting wire of erosion machine with upper and lower feeds - using rinsing head to supply rinsing liquid and at least pressure rinsing pump to deliver rinsing liquid from cleaning tank
Inventor: BRECHT DAVID
IPC: B23H7/10
Filed: 1991-06-17
Abstract: The rinsing liquid is delivered by a first output regulated pump (4) from the cleaning tank (1) to the upper rinsing head (2). The rinsing liquid is delivered by a second output regulated pressure pump (5) independent of the first pump (4) from the cleaning tank to the lower rinsing head. The actual value of the presure in the upper rinsing liquid line (8) is measured by a first pressure pick-up unit (6). The actual value of the pressure in the lower rinsing liquid line (9) is measured by a second pressure pick-up unit (7). The pump output of the respective pressure rinsing pumps (4, 5) is regulated by means of the control unit (10) and the pressure measured by the pick-up units (6, 7), such that the actual value of the pressure in the upper and lower rinsing liquid lines (8, 9), by means of the control unit come as near as possible to the variably adjusted specified desired values of these pressures. The system also includes rinsing feeds (12, 13) for the respective rinsing heads (2, 3), actual value transmitters. The pressure pick-up units (6, 7) are arranged in the rinsing feeds. The control unit (10) is provided with an interface (16) communicating with the control of the wire erosion processing machine or a storage programmed control. ADVANTAGE - Suitable for automatic and manual control. Economic use of rinsing liquid and power consumption of pump motors.

Patent DE-4235295-A1 (DE)
Inventor: HASSEBERG HANS-ALBRECHT DR
IPC: C07C323/58
Filed: 1992-10-20
Abstract: The direct saponification of methionine nitrile obtained from methylmercaptopropionaldehyde, prussic acid and ammonia gives low yields, catalyst and educt losses and unwanted side-products. The aim of the invention is therefore to provide a method which can be carried out without isolating the intermediate products, in particular continuously, and with low losses. The ketone used is recovered in high yields after amide saponification since this liberates the ketone from side-products. In order to recover the ammonia, it is necessary for the ammonia to be substantially freed of ketone, the mixture of ammonia, ketone and water obtained being separated under pressure in a separation column. When the amide is saponified at  >/=  160  DEG C, amide concentrations of less than 25 % by wt. are preferred. Methionine nitrile is produced by treatment with at least 4 equivalents of  >/=  50 % by wt. ammonia at between 40 and 80  DEG C for between 5 and 60 min. Cyanide residues are destroyed by heating to over 150  DEG C. Methionine is of particular use as a feedstuff, in particular in aqueous solution.
