Abstract: Inventor: Gerald B. Klein Title:     A METHOD OF AFFIXING ROD WRAPS TO A            FISHING ROD                 ABSTRACT OF THE DISCLOSURE     Wraps to hold line guides on a fisherman's rod are formed as sleeve-like units which may include an embed-ment of a length of wound thread in a clear, elastomeric plastic resin, or which may comprise a cylindrical sleeve of elastic plastic resins. The sleeve-like wraps are expanded in diameter by any conventional expanding tool and then chilled, or "frozen" to remain in an ex-panded state after the expanding tool is removed. While expanded, the wraps are fitted onto a fishing rod and over the face of line guides on the rod. Thereafter, warming of the frozen wraps to ambient temperatures per-mits them to contract to their original size to fit tightly upon the rod.

Abstract: ABSTRACT OF THE DISCLOSURE           A pump wherein the parts of the casing forming, together with the partitions and sealing members, chambers for the accom-modation of impellers mounted in a counteropposed manner on the shaft, are interconnected in the plane perpendicular to the rota-tion axis of said impellers by means of a clamp.  The clamp con-sists of two parts with the joining plane passing through the rotation axis of the impellers and has circular collars at the edges, said collars entering circular recesses provided in flanges located on the opposite sides of the casing parts.  Said clamp is adapted for compressing the sealing members while the clamp parts are being brought together.  Such a design of the pump casing ensures a more rapid replacement of the worn pump units and parts as compared with the existing pumps.

Abstract: Abstract of the disclosure For amplifying the photosensitivity of a ferroelectric crystal in which information is to be stored, an external field applied to the crystal is created by means of a heavily doped, reduced photocell crystal illuminated uniformly by ra-diation within the absorption band of the crystal. The photo-cell crystal connected to the terminals of the lightly doped, non-reduced ferroelectric crystal, of which the resistivity is very much higher than that of the photocell crystal, deve-lops a very high voltage which relaxes with a high time cons-tant. Such a voltage increases the variations in the birefrac-tion of the ferroelectric crystal.

Title: Fuse with housing end caps secured by magnetic pulse forming
Inventor: BERNATT JOSEPH
IPC: H01H85/042
Filed: 1976-10-01
Granted: 1981-01-27
Abstract: ABSTRACT: End ferrules of a current limiting fuse are mounted to the end of a relatively fragile non-metallic insulator housing of the fuse by magnetic pulse forming. The end ferrules are formed so that there is a flat circular end wall and an annular mounting flange. The flat circular end walls are of a first thickness sufficient to withstand mechanical forces that may be experienced due to fuse operation or due to mounting of the fuse. The annular mounting flange is of a second thickness less than the first thickness so that the flange can be compressed around the housing by magnetic pulse forming without causing undue stress to be exerted on the housing that may result in damage to the housing. A unique elastomer ring seal is provided between the housing and the end ferrule to assure a moisture tight seal. The method disclosed is applicable to allow compressive attach-ment of a variety of metallic members to a variety of rela-tively fragile members so that the strength of the metallic member may be maintained, but the metallic member may be compressed without damage to the fragile member.

Abstract: Abstract of the Disclosure An exhaust pressure responsive flow control valve is disposed in a secondary air supply passageway leading from the atmosphere to engine exhaust system.  The valve has a valve member of a material which is movable by influence of magnetic fields and an electromagnet means for urging the valve member toward  a valve closed po-sition upon passing of electric current therethrough.          First circuit means is provided which permits a rela-tively large current through the electromagnet when the exhaust gas temperatures are so high as to overheat the exhaust reactor or converter closing the valve to block secondary air supply through the passageway.          Second circuit means is provided which permits a relatively small current through the electromagnet at normal stable operating conditions of the engine to restrict secondary air supply.  At acceleration when a relatively large amount of secondary air is required no current is per-mitted through the electromagnet to open the valve.
