Abstract: The invention relates to a method of filling a container (62) and to a pressurizing unit (60) comprising a first and a second pressurizing station (64,75). A transport member (61) transports the containers (62) along the pressurizing stations (64,75). An applicator (66) supplies a liquid pressurizing medium into the containers (62) at the first pressurizing station (64). A feeding unit (68) closes the containers with a cap (70). The cap has an additive chamber that is in fluid communication with the container interior via a valve. The applicator (77) at the second pressurizing station (75) supplies liquid pressuring medium to the additive chamber of the cap (70). A sealing station (80) seals the additive chamber such that the pressure 10 inside the additive chamber is lower than the pressure in the container. Upon opening of the cap by a consumer, the contents of the additive chamber are injected into the container.

Abstract: The invention relates to a modular construction system, comprising at least two construction elements (20) and a coupling element (1), wherein: the coupling element (1) comprises a body (2) with two surfaces which are each provided with coupling means, wherein the coupling means of at least one surface comprise a ring of resiliently pivotable lips (4) provided with locking protrusions; at least one of the two construction elements comprises an opening (22) for receiving the lips of the coupling element; the lips are adapted to displace inward in order to release the connection between the coupling element and the construction element; and the plate-like body of the coupling element comprises an opening (6) which is provided with resiliently pivotable tongues (7) extending radially inward which are connected to the lips (4), wherein the tongues are displaced out of the plane of the plate-like body by a force being exerted thereon, such that due to displacement of the tongues the lips are displaced inward.

Abstract: A frame for a clap skate comprises: a lower frame part; an upper frame part with means for coupling to the sole and heel of a skate shoe; hinge which couples the two frame parts hingedly to each other and which are situated at a distance above the foremost zone of the lower frame part and define a first free degree of freedom of rotation, or a plane varying a maximum of about 30° therefrom of the runner; and resetting means for urging the upper frame part to a rest position determined by positioning means, in which rest position the frame parts have the smallest possible mutual distance. The hinge defines a second free degree of freedom of ±30° perpendicularly of the first free degree of freedom. The upper frame part performs an up and downward and lateral pivoting movement relative to the lower frame part.

Abstract: The invention relates to a coupling between two objects via a coupling element. Each object comprises a panel with a continuous hole with four inward protruding tongues which are disposed at 90° to each other and extend over angles of about 22.5°. The coupling element comprises a shank, an insert stop member on both sides so that the coupling element can be inserted in the one or the other direction into the hole, four locking cams on each end zone of the shank which each extend over angles of 22.5° disposed at 0°, (90°?22.5°), 180°, (270°?22.5°), and rotation stop members. The coupling element can be inserted into the hole in a chosen orientation as desired in one of four equidistant angular positions and then rotated through about 22.5° in the one or the other direction, wherein rotation locking means fix the chosen angular position.

Abstract: A coupling between a first body with a hole and a cylindrical end zone of a second body to be inserted therein, in which hole extend elastically deformable tongues, the free end edges of which tongues lie on a circle, the diameter of which is smaller than the outer diameter of the end zone, which tongues bend in the insertion direction when the end zone is inserted and scrape over the surface thereof with their free edges such that after inserting the end zone over some distance the movement in a backward direction is blocked. The end edges of the tongues have an inclining position corresponding to a part of a helix, so that during a relative rotation of the two bodies, the form of the helix is followed whereby an axial relative movement also occurs and the end zone can be removed from the hole.
