摘要： An equivalent to the spatial separation either side of a nominal median plane that is inherent in a bimorph (with one piezoelectric layer on one side, and the second on the other side of the plane) is attained by structurally shaping the cross-section of a simple, single piezoelectric layer (11) such that it has a multiplicity of piezoelectric portions arranged in two generally-planar groups one either side of a median plane, so that any dimension change undergone by a portion on one side of that plane will tend to bend the whole device in the opposite direction to the same sense dimension change undergone by a portion on the other side of that plane. The simple, single layer acts as though it were a bimorph if elongate and beam-like, bending along its length, one end moving up/down, or back/forth, relative to the other but with any need for an internal, electrode.

摘要： A loudspeaker comprises the casing (22) of a portable electronic device, having mounted thereon a sound generating element (21) which may be a transparent cover for a display. The sound generating element (21) is driven to generate sound by a piezoelectric actuator (1) extending along a sector of a circle and coupled at one end (7) to the casing (22) by a first block (24) and at the other end (8) to the edge (26) of the sound generating element (21) by a second block (25). The first block (24) and the second block (25) each have stop surfaces spaced apart from each other and capable of engaging each other to limit the amount of relative movement of the ends (7) and (8) of the actuator (1) to prevent damage to the actuator (1). The sound generating element (21), the first and second blocks (24) and (25) and the actuator (1) form an assembly which may be manufactured for subsequent assembly to the casing (22).

摘要： A camera lens actuation apparatus for driving motion of a camera lens supported on a support structure by a suspension system. The apparatus incorporates a subassembly comprising SMA wire connected to at least one mounting member which is mounted to the support structure. At least one pair of lengths of SMA wire are held in tension between the camera lens element and the support structure at respective acute angles to the optical axis applying a tensional force having a component along the optical axis. The lengths of SMA wire in the pair are held at angle as viewed along the optical axis. There may be plural pairs with a balanced arrangement in which the forces generated have no net component perpendicular to the optical axis and generate no net torque around any axis perpendicular to the optical axis. A control circuit controls heating of the SMA wire in response to a measure of its resistance.

摘要： This invention provides a method and apparatus (100) for detecting small glass particles (12) in bottles (1) filled with beer (10). The beer (10) is caused to rotate with respect to the bottle (1), and successive images are obtained from the bottle by means of a CCD-camera (40) which is arranged such that its optical axis (41) makes an angle &agr; of about 135° with the axis (13) of the bottle (1), which is illuminated from below. The successive images are subtracted from each other to detect refracted light emanating from glass particles. These measurements are repeated a plurality of times. The invention thus offers an improvement in sensitivity and reliability of a detecting method. An apparatus (100) comprises a carousel (103) with a plurality of cameras dedicated to a single bottle. A system is described to reduce costs by having eight cameras share one image processing unit.

摘要： Described is a hook for hanging articles, such as garments, which is capable of holding the weight of a typical garment while permitting the release of heavier objects. The hook has a base, an arm pivotally mounted to the base, a releasable connecting means for releasably connecting the arm to the base to maintain the arm in a load bearing position, the releasable connecting means (e.g. magnetic means) releasable to permit the arm to move towards a load releasing position when a load having a weight in excess of a predetermined weight is applied to the arm; and effort imparting means (e.g. a weight) mounted to the arm for returning the arm to the load bearing position after the load has been released. Such hooks are particularly useful in schools to reduce the possibility of children being hung from hooks.

摘要： A pipe comprises an outer surface and an inner surface, where the inner surface includes an abrasion resistant material layer covering a substantial portion thereof. An adhesive layer affixes the abrasion resistant material layer to the inner surface. The abrasion resistant layer can reduce and prevent erosion-corrosion of the inner surface of a pipe transporting slurry.

摘要： A hook for hanging articles is capable of holding the weight of a typical garment or knapsack while permitting the release of heavier objects. The hook has a base with two spaced-apart outwardly extending brackets and an arm pivotally mounted to and between the brackets. The arm is pivotable between a load bearing and load releasing position. A first magnet is secured to the arm and a second magnet is secured to the base. The first magnet is magnetically connected to the second magnet to maintain the arm in the load bearing position. The magnetic connection is releasable to permit the arm to move towards the load releasing position when a load having a weight in excess of a predetermined weight is applied to the arm. The first magnet provides weight for returning the arm to the load bearing position after the load has been released. Such hooks are particularly useful in schools to reduce the possibility of children being hung from hooks.

摘要： Apparatus for seaming a container end E to an open end of a container body B, comprises a pad to support the container body, a seaming chuck to support the end E in place on the container body B and cooperating with the pad to hold the container body and end one against the other, and an annular seaming tool having two annular seaming profiles on its inner surface which surrounds the end for progressively folding peripheral portions of the container body and end together to form a seam. The annular seaming tool is mounted on a tool holder and means are provided for supporting and driving the tool holder in orbiting motion such that the axis of the seaming tool follows a circular path around the axis of the seaming chuck. The seaming tool is mounted on the apparatus for free rotation about its axis such that when the seaming profile engages the peripheral portions of the container end, it is free to roll around the end to form the seam progressively.
