Abstract: Bulk sorting using a bulk sorting machine that comprises a conveying means (7), an exciter (5) for generating a separating force, a splitter (1) with a blade, and a sensor (2) that senses the particles hitting the blade. The signal generated by the sensor (2) is used to optimize the result of the separation process.

Abstract: The invention relates to a patella gripper for a patella, comprising a retaining element (3; 53) and a contact finger apparatus (4; 54), wherein the contact finger apparatus (4; 54) is arranged on the lower face of the retaining element (3; 53), wherein the contact finger apparatus (4; 54) comprises at least two contact finger units (4.1, 4.2; 54.1), which are arranged on opposite sides of the retaining element (3; 53), and wherein the contact finger apparatus (4; 54) is designed in such a way that the patella can be moved in the cranial-caudal direction and in the medial-lateral direction by means of the contact finger units (4.1, 4.2; 54.1). The invention further relates to a device (20; 60) having such a patella gripper (1; 51).
