Abstract: A microscope plate indexing apparatus includes a base platform and an indexing platform. The indexing platform has a slideway to slidingly receive a crystallography or other microscope plate. The indexing platform includes two projecting pins, one of which is a guide pin received in a guide groove in the base platform and the other of which is an indexing pin received in one of a plurality of indexing holes in the base platform. The indexing holes are preferably located in an indexing groove. The guide groove keeps the indexing platform aligned with the base platform during movement of the indexing pin from one indexing hole to the other and maintains the indexing platform in substantially fixed position in relation to the base platform when the indexing pin is in a selected indexing hole to insure correct alignment of the two platforms.

Abstract: A scissor is made more ergonomic and comfortable to use by the addition to the upper loop handle of the scissor of an enlarged handle portion that fits into and can be held in the palm of a user's hand without the user's thumb passing through the loop handle. One or more of the user's fingers are passed through the lower loop handle in normal manner to operate the scissor. The enlarged handle portion may be secured to the upper loop handle of existing scissors or scissors may be manufactured with the enlarged handle portion included rather than or in addition to the normal loop handle. As an add on, the enlarged handle portion may include two halves secured together to capture and hold a portion of the upper loop between the halves to thereby secure the enlarged handle portion to the upper loop handle.
