Abstract: A suction gripper for transferring ophthalmic lenses from a storage cup into a centering cup has a suction head with several suction openings and several suction cups, wherein the suction cups are positioned on a convexly rounded surface. At least some of the suction openings are arranged in the suction cups and at least one suction opening is arranged remote from the suction cups on the suction head. The suction gripper is used in a manipulation system for ophthalmic lenses that encompasses ophthalmic lenses, a storage cup, a centering cup and the suction gripper.

Abstract: A process and apparatus for detecting impurity particles in fluids, particularly in infusion solutions contained in bottles, with the apparatus including illuminating and etecting device for defining an optical path through which a fluid is conveyed along a fluid conveying path. To increase reliability of detection, pure air is blow from the optical path into a fluid conveying channel thereby ensuring freedom from dust. The conveying channel of the fluid in a vicinity of the illuminating and detecting device, in a direction of the optical path, has an opening, and a blower having a filter is located on the other side of the opening, as viewed in a direction of the conveying path.

Abstract: This disclosure relates to a device for the uptake of capsule parts. The device may include a female member having an internal cavity defined by a contact surface which engages the outer surface of the capsule, or a male member having an outer contact surface which engages the inner surface of the capsule. In each embodiment of the invention the device includes at least one channel opening into the contact surface thereof for supplying a source of underpressure or overpressure to the capsule. The underpressure creates a suction which facilitates the uptake and holding of the capsule, while the overpressure ejects the capsule from the device.
