Title: Purified insulin suitable for injection
Inventor: JOERGENSEN KLARS HOLGER
IPC: C07K14/62
Filed: 1969-08-07
Abstract: Antigenic insulin free from original pancreatic proteins of mol. wt. greater than 6,000 and comprising a single substance when determined electrophoretically on a polyacrylamide gel is prepared by subjecting insulin to filtration through a gel, esp. a polyacrylamide or a cross-linked dextran gel then to a final purification by passing the product over an ion exchange resin. The first filtration removes protein of mol. wt. over 6,000 and the second purification removes mono-desamido-insulin and "arginine-insulin". The two stages may be combined by using a strongly basic ion exchange resin of the cross-linked dextran type viz QAE-SEPHADEX A-25.

Title: Self adjusting vehicle clutch pedal - for mechanical clutch with spring loaded coupling catch to clutch shaft
Inventor: LANGER PAUL
IPC: F16D13/75
Filed: 1973-06-06
Abstract: The clutch pedal operates on a rod guided through a friction support and fitted at the end with a spring loaded catch. This grips a shaft which operates on the mechanical linkage of the clutch. A spring tag secures the position of the catch on the shaft so that when the pedal is depressed the catch grips the shaft at the furthest extent, and thus sets the clutch pedal play to a standard amount irrespective of clutch wear. A stop on the pedal prevents excess travel outwards when released. Initial play is taken up against a compression spring.

Title: Foam head for pressure atomizer package - has nozzle extension beyond edge of valve plate to prolong foam outlet channel
Inventor: GROTHOFF HANS
IPC: B65D83/14
Filed: 1973-07-31
Abstract: Foam head for a pressure atomizer package with a protective cap can be set with a widened section of a passage channel on a tubular valve actuating shaft of a delivery valve fastened in a dome of the cover of the package. The bottom end is near the cylindrical inner face of the edge of the valve plate, spaced above an annular groove floor of the plate. A radial foam outlet channel connects with the interior of the package. On actuation of the head a nozzle extension can be ejected or travel from it, long enough to extend out over the edge of the valve plate in the delivery position, in which the extension prolongs the foam outlet channel. The head fills the whole height under the protective hood, simultaneously fills the plate, and has a foam outlet reaching over the can edge; the head, however, can pass under the protective cap.
