Abstract: Polycationic polyquaternary products as defined in Claim 1 are useful as adjuvants in paper-making, especially as fixatives in the production of paper from coated broke.

Abstract: Aqueous solutions of polycationic polymers (PAB) containing quaternary ammonium groups in salt form as heteroatomic chain members or ring members of the polymer, wherein a part of the counter-ions to the quaternary cationic groups are anionic groups of anionic optical brighteners, containing at least one anionic group, are valuable multi-functional agents in papermaking.

Abstract: A power feed for a submarine communications system includes a plurality of power converters each of which has at least 2 step-up transformer stages in which at least one of the windings of at least one of the transformer stages of at least one of the plurality of power converters is wound using a high voltage insulating wire to insulate against a high DC voltage appearing at an output of an adjacent power converter. The use of high voltage insulating wire removes the need for expensive custom built DC blocking capacitors.

Abstract: This invention provides a simple skeletal muscle linear pull energy convertor which can harness the maximal amount of muscle power for a wide variety of implantable medical devices, including the full range of circulatory support devices. The muscle powered system provides completely implantable circulatory support as an alternative to cardiac transplantation, with a quality of life relatively free from external batteries, transcutaneous energy transmission and other electromechanical hardware.

Abstract: A system for detecting and measuring corrosive reaction of metals in an environment. The system includes: a remotely placeable sensor head containing a galvanic couple made of metals identical to those involved in the corrosion problem, with the couple coiled in the shape of a sprial; and, operatively associated electronic circuitry to amplify, integrate, and store in a non-volatile memory, e.g., a bubble type memory, for future recall the amount of galvanic current that is flowing and that has flowed when corrosion is, or has been, occurring.
