Abstract: A hopper for feeding beans contains a container for the beans, a closing bottom disposed rotatable with respect to the container in order to selectively open and close an outlet aperture for the beans, and feed means which can be selectively driven to feed the beans toward the outlet aperture. Also provided are an apparatus and a method for grinding the beans, a machine, and the corresponding method for preparing a beverage.

Abstract: Grinding apparatus including a hopper provided with feed means, the hopper being configured to contain and feed the beans, a grinding device configured to grind the beans, and weighing means for weighing the beans.

Abstract: Grinding apparatus for grinding a substance in the form of beans into powder, including at least one hopper removably connected to a support structure, a grinding device configured to grind the beans, and weighing means for selectively weighing the hopper and the beans present therein.

Abstract: A support head for an optical or video-photographic apparatus, having a first body traversed by a first axis of rotation with respect to a base of the head, a second body coupled in a rotary manner to the first body, a third body traversed by a second axis of rotation, and being coupled in a rotary manner to the second body. A user may lock by a single movement of a control member both the relative rotation of the first and second bodies about the first axis and the rotation of the second and third bodies about the second axis. The lock may be a tie-rod extended from the control member along the second axis and a slider connected to the tie-rod and interposed between the first body and the second body configured to lock the relative rotation of the second body with respect to the third body.

Abstract: A support head for an optical or video-photographic apparatus, comprises a first body (302) traversed by a first axis (Z) of rotation of the apparatus with respect to a base of the head, a second body (303) coupled in a rotary manner to the first body in order to rotate about the first axis, a third body (304) traversed by a second axis (X) of rotation of the apparatus with respect to a base of the head, this second axis being substantially perpendicular to the first axis, and the third body being coupled in a rotary manner to the second body in order to rotate about this second axis, as well as locking means (330) able to lock, by a single movement of a control member (331) which may be carried out directly by a user, both the relative rotation of the first and second bodies (302, 303) about the first axis (Z) and the rotation of the second and third bodies (303, 304) about the second axis Y.

Abstract: A support head for an optical or video-photographic apparatus comprises a first body (2) including a pin (7) extended along a first axis (Y) of rotation of the apparatus with respect to a base of the head, a second body (3) coupled in a rotary manner to the pin of first body in order to rotate about the first axis, a third body (4) traversed by a second axis (X) of rotation substantially perpendicular to the first axis and coupled in a rotary manner to the second body in order to rotate about the second axis and locking means (30) able to lock, by a single movement of a control member (31) which may be carried out directly by a user, both the relative rotation of the first and second bodies about the first axis and the relative rotation of the second and third bodies about the second axis.
