Abstract
Abstract A signal collector system, in particular for electrical body signals, consisting of at least one electrode and a contact paste which is to be introduced, at the applicating location, intermediate the body and the electrode. The electrode provides for the extensive avoidance of the effect of the forces and twisting moments which attack it in its applied condition by forming on the body a homogeneous contact paste and adhesive with a conductive substance having a salve or syrup like consistency for the electrode.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
137 words
In a signal collector system, particularly for electrical body signals and the like, including at least one electrode connectable to a signal cable; and an electrically conductive paste positioned on said electrode at an application location, said electrode comprising means for extensively eliminating effects of forces and torques acting on said electrode in the applying position thereof, said paste forming a contact paste and adhesive for the electrode on said body, the improvement comprising: said contact paste comprising polyethylene glycol (PEG) as the base material thereof, said base material comprising mixtures of polyethylene glycol with at least one portion being fluid at body temperature and another portion being relatively solid at body temperature, said one portion of said mixture having a molecular weight of about 400 and said another portion having a molecular weight of about 6000.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
29 words
A system as claimed in claim 1, said base mixture, relative to the entire paste, being about 50 percent of PEG 200 and about 35 percent of PEG 6000.
Claim 4
Dependent Claim
33 words
