Abstract: A strain sensor device for measuring tension on a web or strand member including a frame member, a shaft member extending from the frame member and having a web or strand engaging member mounted thereon, the strain sensor device supporting one portion of the shaft on the frame member.

Abstract: A housing for magnetic particle devices comprising first and second housing members adopted to be assembled in side-by-side axial relation, at least one of said housing members having an annular cavity formed extending inwardly on one side thereof adjacent to the other housing member, an annular tapered surface formed on the side of one of said housing members at an intermediate location radially of the annular cavity and a sidewardly extending annular flange formed on the other housing member for engaging the annular tapered surface to divide the annular cavity into inner and outer cavity portions when the first and second housing members are connected, the annular flange separating the cavity into separate portions on opposite sides thereof, and members connecting the first and second housing members together whereby the annular flange moves axially against and is deformed by engagement with the annular tapered surface to seal between the separate cavity portions.

Abstract: An apparatus for measuring and monitoring the tension on a web or strand as it extends and/or moves over and around a roll including a support assembly for supporting at least one end of the roll, said support assembly including a bridge structure having spaced connected bridge portions aligned with the roll on opposite sides of the axis thereof, a mounting member attached to anchor one end of the bridge structure in fixed position, a diaphragm member attached to the opposite end of the bridge structure, a mounting structure for attaching the diaphragm member to the roll, at least two and preferably four strain sensitive gage members attached to one of said spaced connected bridge portions, and a bridge type electric circuit including circuit connections to said strain sensitive gage members.

Abstract: A magnetic particle apparatus having spaced relatively movable members with magnetic particles positioned therebetween and electromagnetic field producing mechanism to generate a magnetic field between the relatively movable members through the magnetic particles to establish coupling therebetween, the improvements to such apparatus being embodied in an improved cast iron construction for many parts of the subject apparatus, a more efficient safer apparatus, improved apparatus for circulating cooling air through and closely adjacent to the heat producing components to dissipate heat generated while providing support for the drive cylinder and maintaining the magnetic particles in their most advantageous positions, an improved magnetic gap construction which minimizes flux leakage and increases operating efficiency, including a saturable bridge which enables use of a bobbin of one-piece construction without shunting out flux, and the present construction includes structural members arranged to form a circuitou

Abstract: A magnetic particle device such as a magnetic particle brake in which the flux producing means are mounted in a stationary member, said device having improved means for dissipating heat, improved means for locating the heat sensitive members including the bearing members relatively remote from the region where most of the heat is generated, the rotatable portions of the subject devices being mounted between stationary portions thereof, and means forming an improved magnetic gap construction for such devices. The device may also include improved means for circulating a liquid coolant from an external source through stationary portions of the device and simplified relatively trouble free means for making the electrical connections to the flux producing means.
