This invention relates to an interlocking type plastic tile structure in which the surface layer having a pattern thereon is coated with adhesive and then is combined with a PVC base layer adhered to the floor. A plurality of protruding tongues and a plurality of notches are respectively formed on two adjacent sides of the PVC base layer. With this structure, when two such plastic tiles are interlocked with respect to each other, the notches having adhesive layer are interlocked and adhered with the protruding tongues correspondingly so as to achieve assembly and good alignment. Besides, there is no need for providing release paper, therefore cost can be saved and assembly is very convenient.

A carton of the wrap-around type has a pair of overlapped base panels. One of the base panels which carries a locking tab overlies a tongue protruding from the end edge of the other base panel. The protruding tongue is formed with a complementary locking aperture engaged by the locking tab to secure the overlapped panels together. On either side of the locking tab, the said one base panel has a hinged tab protruding from the end edge of that panel. Each of the hinged tabs underlies the end edge of the other base panel, one on each side of the protruding tongue. This ‘over and under’ arrangement presents less of an externally overlapped edge than is the case of a simple complete overlap and thus mitigates against the base panels being skewed or prized apart leading to tearing and / or dislodgement of the locking means.

An arrangement and method of use for supporting a plurality of vertebrae in a cervical column in predetermined spatial relation and for facilitating a spinal fusion procedure. A plurality of templates (12, 14) couple to respectively associated vertebrae at anterior lateral surfaces thereof. Such coupling is effected with fasterners, such as bone screws (19). The templates are slidingly coupled to each other by a coupler assembly (22) whereby they are displaceable along a path over a limited distance that is substantially parallel to the longitudinal axis of the cervical column. The sliding displacement between the templates is limited by a pair of protruding tongues (27) that extend through elongated apertures (29). The elongated dimension of the apertures determines the extent of sliding travel, which extent is established to accommodate subsidence of the bone fusion and to prevent separation of the sliding elements of the coupler assembly. The coupler assembly is coupled to each template by engagement between posts (18) and post holes (15). Additionally, locking plates and fasteners, such as threaded fasteners, are used to ensure the security of the engagement between the templates and the coupler assembly. Sequential replication of the arrangement enables three or more vertebrae to be supported in the determined spatial relation.

An electrical connector for electrically connecting an integrated circuit package to a circuit substrate includes a first and a second unit sections, and each unit section has a number of terminals received therein. Each unit section includes a mating surface, an opposed mounting surface, a fixing edge, and an engaging edge.

The invention relates to a positive-pressure pinch valve which comprises a front guide pipe, a pipe sac, a clip and a back guide pipe. The positive-pressure pinch valve is characterized in that the front guide pipe and the back guide pipe are respectively bonded on outlets at both ends of the pipe sac; and the pipe sac is arranged in an internal space defined by the clip. In the liquid infusion process, the positive-pressure pinch valve is arranged on a retained pipeline; after the infusion process is finished and the connection with the retained part is cancelled, the clip is compressed by hand, so that a protruding tongue on the clip and a fastener are fastened together; meanwhile, two pressure plates on the clip, extending towards the internal space of the clip, forcedly reduce the internal space of a spherical sac on the pipe sac until the internal space is pinched off; and at this moment, liquid in the spherical sac flows in a treatment direction so as to form a positive pressure. When the positive-pressure pinch valve is reused, the spherical sac can automatically recover the smoothness of the infusion pipeline under the action of the own elasticity of the spherical sac by simply unclosing the clip.
