Abstract: A tangential force sensor is used instead of a coaxial strain gauge to measure the torque required to produce the rotation of a part. The force sensor is coupled tangentially to the rotating part through a non-slip contact produced by a force applied radially on the part. A progressively increasing tangential force produced by translating the force sensor in a direction normal to the axis of rotation of the part is then applied to initiate and maintain its rotation. The radial force applied to the part is judiciously selected and measured such that the part is engaged with enough friction to ensure a non-slip condition. By measuring the tangential force applied to the part, the torque characteristics of the rotatable part are determined. By sensing and controlling the radial force applied to the part, damage to the part or the mechanism supporting it is avoided.

Abstract: The football snap aid simulates a snap of a football by a center to a quarterback located behind. The football snap aid includes an apparatus that supports a padded release lever from below, and which when engaged in an upward movement shall release a spring-loaded arm that supports a football on a cradle. The spring-loaded arm translates from a lowered position to a hiked position so as to simulate actual movement of the football during a snap. The football snap aid includes an upper handle and locking tab that can rotate to reset the spring-loaded arm between uses. The apparatus includes adjustable legs that can accommodate differently sized end user. The spring-loaded arm includes adjustment means to accommodate differently sized end users.

Abstract: The present invention relates to a two part thermally conductive adhesive composition comprising: a first part comprising: a polymerisable monomer component which is (meth)acrylate based; a peroxide-based curing agent component; one or more co-curative components selected from: primary, secondary or tertiary amines or compounds containing the group —CONHNH—; a stabilising component; a thermally conductive filler component; and a second part comprising: a polymerisable monomer component which is acrylate or methacrylate based; a catalytic component for catalysing the cure reaction; a stabilising component; and a filler component wherein at least one part of the composition has a filler component which comprises a thermally conductive filler. The thermally conductive filler can be in the first part or the second part or both parts but is desirably in the second part. The compositions are useful for bonding heat generating components such as electrical components to a substrate such as a heat sink.
