Patent number: 7854894Abstract: Feed devices for liquid samples serve to convey liquid samples, for example to convey a liquid sample from waste water in a waste water treatment plant so as to monitor the treatment process. Known feed devices feed continuously at relatively low speeds. Films may accrete in the feed line that hinder the feeding and may react with the liquid sample. Therefore, the feed line must be cleaned frequently. In view of this, it is the object of the invention to improve the handling and the maintenance of a feed device for liquid samples. According to the invention, this object is solved by the fact that the feed pump (16) feeds in a pulse-like manner and the feed pump (16) as well as the feed line (18) are configured such that the expansion volume of the feed line (18) during the feed pulse is at most 50% of the pulse volume. Thereby, the feed line is cleaned and kept free of accretions.Type: GrantFiled: July 29, 2005Date of Patent: December 21, 2010Assignee: Hach Lange GmbHInventors: Klaus Bittner, Michael Kussmann

Patent number: 4144804Abstract: In a milk processing system wherein heat treated milk is initially separated into high-fat and low-fat milk and subsequently reconstituted by adding a selected proportion of high-fat milk to the low-fat milk, control means are provided for automatically controlling the proportion of high-fat milk mixed with the low-fat milk to provide a milk blend of standardized butterfat content which is then homogenized. The control means includes a photoelectric monitoring system for continuously measuring the butterfat content of a sample of the homogenized milk as the latter flows continuously through the processing system under pressure of the homogenizer in the system. The butterfat content measurement is converted to digital signals which are compared to a pre-set digital signal corresponding to a desired butterfat content level to produce a digital corrective signal which controls a digital valve regulating the proportion of high-fat milk blended with the low-fat milk in the processing system.Type: GrantFiled: October 12, 1976Date of Patent: March 20, 1979Assignee: On-Line Instrumentation, Inc.Inventors: Michael G.
