Title: Numbering unit in typographical set on printing machine - has monitoring numerator producing error signals for unmatched discs
IPC: B41F33/00
Filed: 1975-08-07
Abstract: The numbering unit is designed for incorporation in the typographical set on a printing machine. It is monitored by a numerator which can produce error signals. Each disc (102) of the monitoring numerator has the same number of halting positions as the corresponding disc on the numbering unit being monitored. Each such position corresponds to a location unit which produces a signal. The signals belonging to the two discs are combined. All the signal information from the discs is reorganised to produce an error signal if one disc or more in the monitored numerator is ina different position from the corresponding disc on the monitoring numerator.

Title: Lipids and proteins sepn. from potato cell fluid - obtd. in prodn. of potato starch
IPC: C09K23/32
Filed: 1977-04-29
Abstract: Lipids are sepd. from potatoes by sepg. cell fluid from potatoes and recovering lipids therefrom. Lipids are used as emulsifiers and wetting agents in foods; further uses are in the leather and textile industries, and in cosmetics and pharmaceuticals. The lipids may be isolated from the protein water by extn. with a solvent, esp. a polar solvent for fats, esp. CH2Cl2, CHCl3, CCl4, alcohols, esp. 1-5C alkanols, in partic. (m)ethanol, isopropanol and/or butanol and/or other water-miscible extractants, esp. methylal. Extn. is pref. in countercurrent. Pref., the proteins are pptd. from the protein water, e.g. by heating with injected steam; lipids and proteins are pptd. almost quantitatively. The lipids are obtd. in high yield and pure form from a waste material. Further purificn. is not needed. The lipid content of pptd. potato protein is higher than that of most oil seeds. Removal of lipids from the potato improves the storage stability of the protein. After removal of the lipid-contg. protein, the water can be rejected.
