Patent CA-2057784-C (CA)
Title: Resiliently mounted rigid floor grating
Inventor: BEDICS MICHAEL A
IPC: E04F19/10
Filed: 1991-12-17
Granted: 1995-07-18
Abstract: A resiliently mounted and constructed rigid floor grate assembly is disclosed, in which a series of metallic tread rails of T-shaped cross section, placed side by side and connected by tie rods, are separated by individual, resilient spacing and support elements.   The spacing and support elements are placed between each pair of tread rails, underneath the tread portions thereof, and are held under compression by the tie rods to form a rigid assembly. In addition, the height of the spacing and support elements is slightly greater than the height of the vertical web portions  of the  tread rails,  to  support the metallic elements slightly above the hard surface of a floor recess in which the grate assembly is placed.   Significantly reduced metallic noise and clatter is an important benefit.

Title: Test strip analysis system
Inventor: HOENES JOACHIM
IPC: G01N33/52
Filed: 1994-03-24
Granted: 2001-01-02
Abstract: A test strip analysis system consists of an analysis apparatus with a test strip holding means and matching test strips. The test strip holding means serves to position the test strip in a defined position relative to a measuring unit. It comprises a test strip seating means and a guide for the test strip. Exact positioning with simple handling and without sophisticated mechanical elements is achieved by the fact that at least one part of the test strip seating means, in the area in which, in the measuring position, the front section of the test strip is located, is formed as a support which is offset in height relative to the middle plane of the test field area, the test strip,,holding means comprising at the same time a pressure element which in the measuring position presses between the support and the test field area of the test strip against the side opposite the seating means of the latter. The test strip is consequently subjected to bending stress, whereby the particular distance of the at least one test field from the measuring unit is ensured.
