An apparatus (10) for determining while drilling in the earth with a drill bit (12) the positions of seismic wave reflecting geologic formations (15, 17) has seismic wave sensors (A, B) positioned in the earth near its surface (42). The sensors (A, B) are disposed at known positions with respect to the borehole. The drill bit (12) generates the seismic waves. The sensors (A, B) receive the seismic...

An antithrombotic medical material comprises a high-molecular substrate (e.g. cellulose, chitosan, collagen or fibroin) to which heparin is bound by means of an epoxy compound which can react both with the amino groups of the heparin and with reactive groups on the substrate (e.g. amino, hydroxy, carboxy or mercapto). The epoxy compound is pref. a diglycidyl compound such as 1,4-butanediol diglyci...

Arrangement for a hydraulic lifting table of the scissor type. This has two pairs of mutually attached scissor arms (1a, 1b; 2a, 2b), which at their ends are connected by means of pivots and rollers to a lower frame section (3) and an upper table section (4). The scissor arms (1a, 1b; 2a, 2b) are mutually and operatively connected to the pivotable connection (5) to the frame section (3). The lifti...
