Title: Process for the lowering of the oxidation state of metal salts
Inventor: GLEIM ROBERT DAVID
IPC: C22B3/00
Filed: 1982-05-18
Granted: 1985-09-26
Abstract: The oxidation state of metal salts is lowered by contacting a solution of the salt with polyacetylene in the presence of sufficient moisture to leave the polyacetylene substantially undoped. The metal salt must have a reductive capacity of at least +0.5. This process can be used to reduce metal salts to zero active valency metal. The moisture is effectively added by treating an aqueous solution of the salt, optionally with organic cosolvent. The zero valency metal can subsequently be recovered from the polyacetylene, for example by burning the polyacetylene off.

Granted: 1988-12-29
Abstract: A skin-contacting lubricating layer formed from a hydrogel polymer bonded to a rubber article (such as a surgeon's glove) is treated by means of surfactant material (such as a bactericidal cationic surfactant which preferably has a 6-18C alkyl or alkenyl group, such as an N-hexadecyl group) or a long chain fatty amine so as to substantially improve the lubricity of the layer with respect to damp skin. The hydrogel polymer is preferably a copolymer of 2-hydroxyethylmethacrylate (HEMA) with methacrylic acid (MAA) or with 2-ethylhexyl acrylate (EHA) or with both MAA and EHA. Such a hydrogel polymer has improved lubricity to dry skin and, if used for this purpose, need not be treated with a surfactant or fatty amine to improve the lubricity with respect to damp skin.

Abstract: A dabber printing machine for printing of workpieces with printing ink wherein a dabber-holder is fastened from below to a first and second vertical carriage (6, 6'). The dabber-holders run parallel to one another. In each case, in one extreme position of the horizontal carriage (7), with which both vertical carriages (6, 6') are connected, the vertical carriages (6, 6') are pressed downward by two levers (14) of a pair of gear units (12). In the other extreme position, such are pressed downward by the levers (14) of the other pair of gear units (12). Thus, the dabber-holders with the dabbers jointly and simultaneously make vertical and horizontal movements in the form of an inverted U. A step of operation of the transfer element from printing station to printing station optically occurs upon every or every other horizontal movement. Thus, indexing of the workpieces to be printed is simplified and the efficiency of the printing machine is doubled.
