Toothbrush with toothpaste in aerosol form in a pressurised cartridge (4), containing multiple doses, that has a longitudinally lengthened brush (2) with a front end that is wider and has a rectangular cross section with rounded edges, on one of the larger surfaces of which are installed the bristles (8); a hollow handle (3), containing the pressurised cartridge (4), in which the back end of the brush, has fixing and binding means (13-14-32) with means of equal size and matching cavities, on the front wall of the handle; the outer surface of said handle having at least one annular rim for applying manual pressure; where the cartridge is projected towards the end of the brush, by applying manual pressure on its base, moving it a sufficient distance to cause the end of the duct of its opening valve in a closed condition (24) to butt against the inner edge of the orifice (11) of the end of the brush such that said valve opens (25) and by means of the pressure inside the cartridge, it doses and propels the toothpaste towards the outside of the brush.
The invention relates to an auxiliary aerodynamic braking system for motor vehicles, comprising at least one mobile flap and a vehicle chassis, in which: a) the mobile flaps of the auxiliary brake (28-29-30) are pivotably connected to the lower surface of the vehicle chassis (4); b) actuation means (11, 23) are provided in order to move the mobile flaps between a first operating position in which they are retracted against the vehicle chassis when the braking system is in an inactive state and a second operating position in which they are extended in relation to the vehicle chassis when the braking system is in an active state; c) valve means (17-26) are provided in order to control the actuation of the pneumatic/hydraulic means used to move the flaps between the aforementioned two operating positions; d) the transverse flaps (28) are provided with spaces (47) between the structural reinforcements (34), whereat the edges of the skewed surfaces of the flap (42) converge such as to direct the air towards the aerodynamic systems (38-39); and e) the vehicle chassis (4) is designed to house the mobile brake flaps (28-29-30) and the aerodynamic systems (38-39) thereof in an integral manner, such that they do not project from the lower plane of the chassis.

ELEVATED INFLATABLE POSTER SUPPORT SYSTEM AND PRODUCTION METHOD THEREOF
The invention relates to an elevated inflatable poster support system and to the production method thereof. According to the invention, the frame (f) is formed by a continuous tubular body (tb) which is inflated with lighter-than-air gases and which is crimped by means of transverse seals (msc, msd) or by means of constrictions with transverse rings (r), by moving the ends thereof closer together, such as to form geometric bodies that vary depending on the number used and the distance between the transverse constrictions. At least one of the tubular bodies is provided with an attachment (6) for inflating and deflating same using a sealed tubular body (13) with a valve mechanism (18). The posters comprise fine, resistant sheets which take the form a single piece (p) or which include a plurality of thin laminar tubes (pm). Stabilisers (8, 9, 12) are used to connect the frames to a wire element (10) which is secured to a fixed point (11). Wind resistance is reduced in posters that are provided with perforations (20) or spaces between the components (21) thereof and between the components and the frame (22). In order for the assembly to move in a light wind, a flat body (31) or a similar moving body (32) is fixed between the stabilising bar (12) and the wire connector (10) and a remote-controlled movement mechanism (33) is affixed thereto. The length of the wire connector element is provided with systems for absorbing the force of the wind (23) and for enabling same to rotate freely about the axis (26) thereof in order to prevent any damage that could be caused by excessive twisting owing to the wind. In addition, a light bag having a rigid ring at the edge thereof is joined to the inflatable body closest to the ground using stabilising means (8, 9, 12).
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. Moreover, one end of a hypodermic needle device (10) is coupled to the injection opening and said needle device can perforate the end elastomer seal and communicate with the interior of the tube and be equipped with an injection needle at the opposing end thereof.
The invention relates to a unit (1) for mixing and supplying injectable substances, comprising a plurality of chambers (2, 2a, 2b, 2c) with different cross-sections, which are disposed consecutively from smallest (2) to biggest (2a, 2b, 2c) in an axial direction from the injection end (1a) and which contain the injectable substances (10a, 10b, 10c, 10d) that are mixed (10) when the chambers are communicated following the reverse movement of separating means (5, 5a) and a piston (4) which are moved by a coaxial rod (3) that is disposed in the unit. The separating means and the piston are moved during the use of the mixing unit by means of the compression and decompression of inert gases housed inside each of the compartments or chambers containing the injectable substances. According to the invention, both the injection end (1a) and the control end (1d) are equipped with respective covers (9, 6). The central conduit in the elastomer cover at the control end (1d) is hermetically sealed by the portion of the rod (3) located therein. The invention also comprises other elements (6a, 7c) and clamp means (7, 3a) which prevent the rod (3) from moving until it is activated for operation.
