Abstract: A tissue roll mount is conformed for convenient assembly by providing internal pivot seats subjacent the lower interior edges of each one of two opposed openings formed in the roll supporting arms. Each one of the pivot seats forming a pair is spaced relative the other by a dimension that is smaller than the spacing between the pivots at the ends of cantilevered pivot arms aligned along the vertical edges of a set of opposed pivotal mounts to capture the ends of the arms therein. A block of open-celled resilient foam is then inserted in each arm for capture in compression against the corresponding pivot mount.

Abstract: An apparatus for holding a roll of paper having a mounting section with two arms extending outward therefrom. Each arm is hollow and includes an aperture on the inner surface of the arms. Pivoting members are mounted within the arms and are spring biased into a first position where the pivoting members support the roll of paper. The pivoting members includes cavity shields that prevent the entry of debris into the arms and the springs are secured to the pivoting members and the arms so as to inhibit the springs from being dislodged. The pivoting members are further biased such that the pivoting members can be retracted into a second position as a result of a user moving the roll of paper against the pivoting members in a first direction.

Abstract: A force transducer which uses current pulses in a conductor to generate acoustic pulses in a magnetostrictive delay line. The pulses are sensed by a coil around the line. The magnitude of the pulses is modified by force applied to the transducer by changing the shielding effect of a magnetoelastic ribbon (between the conductor and the delay line) by applying a force to be sensed thereto. The transducers are economic and easily assembled into arrays for sensing stress distribution in two dimensions because the common conductors can be used for the columns of the array and common delay lines can be used for the array rows. Each column then has a common current-pulse generator and each row has a common detector coil. A similar technique may be used for sensing the spatial distribution of other parameters such as temperature, magnetic field or displacement.

Abstract: A force transducer is described which uses current pulses in a conductor to generate acoustic pulses in a magnetostrictive delay line. The pulses are sensed by a coil around the line. The magnitude of the pulses is modified by force applied to the transducer either by changing the shielding effect of a magnetoelastic ribbon (between the conductor and the delay line) by applying a force to be sensed thereto, or in another alternative by modifying the distance between the conductor and the delay line in accordance with applied force. The transducers are economic and easily assembled into arrays for sensing stress distribution in two dimensions because the common conductors can be used for the columns of the array and common delay lines can be used for the array rows. Each column then has a common current-pulse generator and each row has a common detector coil. A similar technique may be used for sensing the spatial distribution of other parameters such as temperature, magnetic field or displacement.
