Abstract: ABSTRACT   A sound pickup, for tracking mechanically modulated grooves in a record support by means of a tracing stylus, includes a stylus holder elastically mounted, at its center of motion, in a bearing element of rubber or rubber-like material.  A small metal plate is embedded in the bearing element to extend perpendicularly to the longitudinal axis of the stylus holder, and has a central opening therein.  The stylus holder passes through the central opening and the diameter of the central opening is slightly larger than the external diameter of the stylus holder in the zone of its passage through the central opening.  The thickness of the plate is small relative to such external diameter of the stylus holder, and the stylus holder is connected to the plate only through the bearing element.  The bearing element is preferably a body of revolution extending to either one or both sides of the plate, with the plate being situated in the plane of the largest diameter of the bearing element, and the bearing element has a passage extending therethrough coaxial with the central opening in the plate and with a diameter less than that of the central opening in the plate.

Abstract: A B S T R A C T      Hydraulic circuits having flexible hydraulic hoses forming part of the circuits are currently being operated at pressures in excess of 3,000 psi, and such circuits are often limited in their operating pressure by the burst strength of the hydraulic hose.  By constructing a hollow core structure that forms the conduit and which serves as the foundation upon which the reinforcing is applied, with a two-layer tape composed of a layer of fabric and a layer of elastomer, which tape is then wound on a mandrel in a helically overlapping relationship with the fabric on the outside, an improved hose can be obtained after the rein-forcing is applied.   An increase in burst strength can be obtained in such a hose where wire cable is employed as the reinforcing in place of monofilament wire reinforcing, when the cable is formed (twisted) as it is applied, to achieve a more uniform tension on each of the strands forming the cable encircling the core structure.
