Abstract: This invention relates to intraocular lenses. More particularly, this invention relates to intraocular lenses that have the ability to alter the light refractive power in response to changes in the tension of the ciliary muscle or ciliary body of the eye or any other accommodative forces. Lenses of this invention are generally referred to as interfacial, i.e., lens properties being defined as the interface of two liquids having different refractive indices, refractive accommodating lenses (IRAL).

Abstract: A method for cutting the lower and at least one upper thread for lead-in embroidering or lead-in sewing is performed with a device including thread catchers (19a-19c) connected with each other in a fixed manner and layered over top of each other, formed of sheet metal, as well as spring and thread tightening plates (31 and 41) arranged above and below the thread catchers, which move back and forth against a blade (29), and a thread wiper unit. The device is exclusively operated by a drive moving back and forth and driving the thread cutting and lead-in stitching unit (5).

Abstract: For the continuous drive of a hook of a sewing machine, two drive cams (17) alternately engage in the back of the hook. During the passing of the upper thread loop, the respective drive cam (17) on which the thread would get hung up is out of engagement. The hook is situated in a conical hook race guide and is held therein by magnets.

Abstract: The invention relates to an apparatus for displacing tissue within the body, wherein the apparatus includes two or more attachment members selectively displaceable with respect to each other via a driving member. The driving member preferably is rotatable and is caused to rotate by manually activating an actuator by applying a depressing force from outside the body.

Abstract: A locking device having a connection element (11) that is securely connected to the hook base (1) but can rotate is provided. On the connection element (11), a coil spring (17) is supported that is compressed after setting the bobbin case (5) on or in the hook base (1). Through a slight tilting movement, the bobbin case (5) or the bobbin (7) could be pushed and guided over the connection element (11) and then held by the force of the spring (17) in the locking position.

Abstract: A locking device for bobbins (3) in the hook base (1) of a sewing machine is provided by a locking element (21) that can move in the axial direction. The locking element (21) is spring-loaded and lies in an ejection and loading position inclined to the rotational axis (X) of the hook base (1), so that the bobbin (3) can be placed or removed. As soon as the bobbin (3) is inserted into the hook base (1), the locking element (21) tips and locks on the bobbin rod (9).

Abstract: From a light source (51), light beams (57) are directed tangentially through the hook body (17), the hook base (27), and the bobbin case (28), onto a light receiver (53). Using the time (t) or the position of angular rotation of the hook body (17) at the impingement of the first light beam (57), the diameter of the bobbin packing on the lower thread bobbin (29) can be calculated.

Abstract: A false-twist spinning unit or apparatus comprises a first spinning disc, such as a top spinning disc and a second spinning disc, such as a bottom spinning disc rotating in opposite directions and arranged in staggered or offset relation at an inter-axis distance from one another such that friction rings thereof form a substantially rhomboid-like crossing surface. Disposed outside the friction rings are suction surfaces which engage the fibers of a sliver delivered from a nip line of an exit roll pair of a sliver feeder and convey such fibers to a yarn core line. The suction surfaces have suction apertures and sucked-off air is transported by suction nozzles coacting with the suction apertures. In operation, at the region of the nip line there is produced a false-twisted yarn core forming a spinning triangle.
