Abstract: A ballistic resistant protective garment having a ballistic resistant pad which has at least three panels including a first panel constructed of a plurality of overlying layered sheets in which each sheet is constructed of a first type of high tensile strength woven fiber, a second panel constructed of a plurality of overlying layered sheets in which each sheet is constructed of lyotropic liquid crystal polymer material, and a third panel constructed of plurality of overlying layers of composite body armor material positioned at a body side of the pad in which the first, second and third panels are in overlying relationship to one another to form the pad. The employment of the panel of layered sheets of lyotropic liquid polymer fibers introduces a synergistic effect with the ballistic resistant materials of the other panels.

Abstract: A necktie dimpling tool for depressing the area below a knot placed in a necktie forming a generally vertical dimple in the necktie just below the knot including a pair of pivotally attached and opposing ribs arranged so that a compressive force is maintained between the pair of ribs. The tool may also include a third or center rib disposed between the pair of ribs. The center rib may be pivotable in relation to the pair of ribs and may be arranged so that a compressive force is maintained between the center rib and/or both of the pair of pivotally attached and opposing ribs.

Abstract: In a fiber processing machine with a separating edge in which fibers as well as air are guided in a substantially predetermined transporting direction past the edge, trash particles are selectively removed from the fiber/air stream with the help of the edge. The adjustment of a separating element, in particular, the setting of the angular position of a separating surface and/or the penetration depth upstream from the separating surface is linked with an adaptation of the width of the eliminating gap. Also, at least one measure can be taken for eliminating, as far as possible, a pressure drop and/or air turbulences downstream (in the transporting direction) from the edge. Downstream from the edge, a flow pattern as laminar as possible is generated or maintained, respectively.

Abstract: A thermal glove fitted to a human hand having integrated with a body of the glove a thermal, gel-filled pack.

Abstract: A compacted yarn is produced by providing a row of orifices subsequent to drafting along which the fiber strand is guided and after which the fiber strand is subjected to a twist according to the invention the suction air flow is monitored at least at one suction location and upon falling below a threshold, a signal is generated which can be used for shutdown or to alert personnel. The result is elimination of the reduction in yarn quality which can occur when the compaction system becomes blocked by lint, fiber accumulation or the like.

Abstract: A pneumatically energized loading mechanism for a drafting device is proposed for loading the upper rolls of the device. This mechanism possesses pneumatic cylinders which subject the upper rolls to a force, which acts from a holder plate (4) for the securement of the cylinder (2). The support is effected by a stop plate (200), which acts in unison with holder plate (4). The cylinder (2) possesses a guide surface (201) positioning the cylinder on the support (4). The cylinder (2) exhibits a piston with a circular cross-section and is comprised of plastic. The cylinder (2) is affixed to the holder (4) by a securement means (20). By the support of the cylinder (2) on the holder (4), the securement means (20) need accept no force engendered by the piston. The cylinder (2) simultaneously forms a passage for a current bus which serves as the power cutoff of the drafting device when fiber windup difficulties arise.

Abstract: A helmet windshield is provided with sunshade device on the top. The sunshade device includes a supporting slice, a pushing block, a slider, a pivotal block and a sunshade slice. The protrusive member of the pushing block is inserted in the opening in the center of the supporting slice and then attached to by the slider. The left and right sides of the slider are inlaid in the sliding groove provided in the inner surface of the supporting slice and surrounding the opening so that the slider can slide upward and downward in the sliding groove. The -shape protrusion of the pivotal block is inserted through the -shape hole of the supporting slice, and the post of the slider is inserted in the hole of the pivotal block. At last, the sunshade slice is combined with the pivotal block by a rivet so that the sunshade slice can move upward or downward according to the movement of the pushing block.

Abstract: A joint protector for protecting a human user's knee or elbow from injury. The protector is comprised of a cushion pad which is shaped to fit about portions of the user's knee or elbow. A cap is fitted about the outer surface of the cushion pad and a flexible cover overlies the outer face of the cap. In one embodiment a support carries a cup-shaped cap that is formed of an elastic, compliant material. The cap elastically deforms, responsive to forces impacting on a small area, in an amount sufficient to spread the forces over a flat area as the forces are transferred into and absorbed by the cushion pad. The cap returns to its initial shape when the impact forces are removed. A mechanism is provided for removably attaching the joint protector to the user's knee or elbow joint.
