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).

Interfacial refraction accommodating lens (IRAL)

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 (-) 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 (and) arranged above and below the thread catchers, which move back and forth against a blade (), 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 ().

Method for cutting the lower and at least one upper thread and a method for lead-in stitching as well as a device for implementing the method

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

Locking device for a bobbin

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