Abstract: A plurality of dosage-control members are detachably connected to the plunger rod of a multi-dose syringe along two opposing sides of the rod. Each dosage-control member has a cut in which the external diameter of the top rim of the syringe fits to prevent forward and reverse movement of the rod. Removal of one dosage-control member from one of the two opposing sides of the rod permits forward movement of the rod and plunger until the top rim snaps into the cut of another dosage-control member. Flexible salient arms extend obliquely from the rod in one-to-one correspondence with the dosage-control members to prevent reverse movement of the rod.

Abstract: The invention relates to a syringe for administering multiple doses of a medicinal substance contained therein, consisting of: a cylindrical tube (1) comprising an injection opening (3) and a mouth (2) and a longitudinally-mobile drive plunger (4), and an actuation rod (5) for connecting to the plunger, said rod (5) being equipped with detachable dose-limiting means (6) which project out from the rod such as to exceed the inside diameter of the tube in order to prevent the forward movement of the rod and the plunger inside the tube. In addition, mouth-limiting means (7, 70) co-operate with locking means (8, 60) such as to prevent the reverse movement of the rod. When closed, the injection opening (3) is provided with an elastomer seal (9) which can be perforated with a sharp element.

Abstract: The present invention is related to a demountable tire rim assembly having a spare inner wheel which permits running during the run flat condition. The demountable tire rim includes two complementary annular parts provided with reciprocal threaded coupling members on the perimeter of the annular parts which include threaded and non-threaded sectors which are structurally arranged to secure the annular parts together.

Abstract: The present invention is an anchoring device for fastening laces which includes a structure having a supporting base and a pair of overlapping throat members which hold sections of the fastening lace. The bottom throat member forms a reel and includes retention ledges which retain a winding section of the lace that is wrapped about the reel. The upper throat member forms a reel having retention ledges which retain a winding section of the lace that may be wrapped about the reel.

Abstract: The present invention relates to a rim member having an internal support member associated with the rim member. The internal support member includes an outer peripheral surface having an annular groove with the groove having a transverse passageway to permit a tire to be mounted onto the rim member. The transverse passageway consists of two angular positions which communicate through an intermediate section on the internal support member. The invention also relates to a tire construction having an internal rolling surface which engages the outer peripheral surface of the internal support member during the run-flat condition.
