When photographic film has been processed and printed, the photographer receives a set of prints and negatives in an envelope. However, because negatives are susceptible to scratching and contamination from dust, dirt and/or fingerprints, the quality of reprints and/or enlargements made from damaged negatives is reduced. Described herein is a method and apparatus which uses heat to bond a polyethy...

A selective release for grippers on a conveyor, each of which has a movable arm and a stationary arm. Arms move toward each other to grip a planar product (e.g. a newspaper) therebetween and move away from each other to release the product. The gripper is biased toward the closed position and can be moved into the open position by the application of a release force. A rocker cam is provided which ...

A passive load limiting strut particularly useful in limiting loads between a spacecraft and an upper stage during booster first stage operation and thereby permit the launching of heavier spacecraft. The strut operates on the principle of snap through buckling of bar linkages. A tension shaft is telescoped into a compression shaft within a housing. A plurality of bar linkages are connected betwee...

An apparatus for producing a plastic lens element having a gradient index of refraction is disclosed in which first and second monomer-containing compositions, each having a different index of refraction, are injected into a centrifugal mold. Precise control of the gradient index is achieved by varying the ratio of the two monomers over a predetermined number of steps during the filling process.

Optically active compounds of the formula I wherein m stands for the number 1 and R2 is an unsubstituted or halogen-substituted alkyl or alkenyl group in which optionally one methylene group is replaced by oxygen and/or optionally one methylene group is replaced by an ester group -COO- or -OOC-; or m stands for the number 0 or 1 and R2 denotes a group of the formula II R1 a...
