Title: Lock for preventing theft of skis - has overlapping locking strips with spaced perforations for accommodating padlock hasp
Inventor: WIEMER KLAUS DIPL ING
IPC: A63C11/00
Filed: 1974-03-11
Abstract: The locking arrangement prevents placing the skiis together by their sliding surfaces. Hence the skiis cannot be taken away and transported in the normal manner. Due to the geometry the skies are awkward to transport in this locked state. A padlock has a hasp which passes through the hole in the straight strips held on the skiis. A strip arrangement on the ski consists of a fixed straight flat strip on which pivots a similar strip. This top strip is swung out and the padlock hasp lasses through the holes at the end of two such strips. The pivoted strips are held firmly in contact with its mounting plates in the stowed position by a spring under the pivot pin head. This spring pushes the top strip with a socket seat on its underside into contact with a projection on the mounting plate.

Title: Centrifugal force simulator for testing turbine blades - has expanding jaws for applying force to root of blade
IPC: G01M7/00
Filed: 1975-04-12
Abstract: The centrifugal force simulator consists of two hand-operated, adjustable hydraulic or pneumatic rams (20). The central operating piston of each ram is in the form of a shallow wedge with flat expanding jaws of spring steel (13, 18). Extension of the wedge forces the jaws apart. The simulated centrifugal force is obtained by positioning the expander jaws in the spaces on each side of the turbine blade root, between the end of the root and the inside face of the slot in the turbine shaft or mounting flange into which the blade is keyed. The progressive expansion of the jaws produce a force tending to displace the blade outward.
