Abstract: A cartridge gun is provided. The cartridge gun comprises a cartridge holder, a plurality of resilient gripping elements, a displaceable piston rod for moving a piston in a cartridge, and an actuating device for displacing the piston rod. The cartridge holder comprises a cylindrical base for receiving the floor region of the cartridge in which the gripping elements project radially outwardly from the center of the cartridge holder in the direction towards the housing into an annular groove of the base up to the outside wall of the annular groove in the base and are held in the center of the base by means of a hub. Means are further arranged at the front end of the piston rod which are designated to press the ends of the resilient gripping elements in the direction towards the housing when the piston rod is fully retracted, allowing the removal of the cartridge from the cartridge gun.

Abstract: A novel pressure control device is provided comprising a first cylinder (3) at a predetermined excess pressure, a piston (4) with a sealing ring (5) being movable within said first cylinder, and a second cylinder (7). The first cylinder (3) is encompassed by the second cylinder (7) as to form a ring-shaped passage which is leading to the outside. A valve in said passageway is released and closed by a stem (14) of the piston (4). The open end of the first cylinder (3) is provided with at least one axially directed incision (37), such that the piston (4) with the sealing ring (5) introduced in the first cylinder (3) and covering the end of the incision (37) is in a non-pressurized position. The stem (14) has a stop element (15) which closes the valve in the upper position of the piston, wherein the piston stroke essentially defines the excess pressure.

Abstract: The present invention relates to a device for removing joint filler and a method of using the same. The device includes a body member and a peeling element located adjacent to the front end of the body member. The peeling element includes at least two peeling points, where the first peeling point is located proximate to the topside of the peeling element and the second peeling point is located proximate to the underside of the peeling element. The device also includes an opening located between the peeling element and body member.

Abstract: A new foam spraying apparatus 1 is described for a liquid container. It comprises a piston and cylinder unit (20; 37) for the air and a piston and cylinder unit (21; 38) for the liquid in which arrangement the piston and cylinder units (20, 37; 21, 38) each are provided with an inlet valve (30; 44) and with an outlet valve (24) and are co-operating being coupled to each other. Furthermore a mixing chamber (14) for the mixture of air and liquid and a spraying head (2) with a foam delivery opening (9) are provided. The cylinder (20) of the first unit and the piston (21) of the second unit are interconnected to an intermediate part (5). Furthermore the piston (37) of the first unit and the cylinder (38) of the second unit are also interconnected to a base part (4) in such a manner that the intermediate part (5) and the base part (4) mesh and are movable relative to each other.

Abstract: The invention relates to a dual-component container system (1) consisting of at least two containers (2, 3) for keeping separately substances which are used as a mixture. Said containers (2, 3) each have a mixing opening (5, 7) which can be closed by means of a sealing cap (6, 8), and are interconnected by means of a connecting piece (4) interacting with sealing caps (6, 8) with mixing openings (5, 7) facing each other At least one (6) of the sealing caps (6, 8) is connected to said connecting piece (4) by means of a clamping joint.

Abstract: Dual component container systems are provided for separately storing at least two liquids, which are intermixed within the system prior to dispensing. Two or more containers having mixing openings are provided wherein the mixing openings are sealed by sealing members. The sealed openings of the containers are interconnected by one or more connecting elements, thereby forming a sealed conduit interposed between containers and wherein at least one of the sealing members is connected to the connecting element by a releasable clamping joint. Systems of the present invention are designed such that relative movement of the two containers causes the sealing members to open or be removed, whereby fluids from the two or more containers may intermix via the open conduit formed by the connecting element.

Abstract: The present invention provides an inhaler device for inhaling an aerosol in a desired dosage, comprising a housing in which is received a reservoir of powder or liquid, an inhaling piece placed on the housing and a mechanism for transporting the powder or liquid from the reservoir to the inhaling piece in a dosage required for the aerosol. A spring biased piston is incorporated into the housing to compress the inhalable medium in the reservoir. The inhalable medium transporting mechanism includes a recess within a reciprocating plunger. The inhaling piece includes two separate air intake openings extending to an exterior of the inhaling piece. The two air intake openings generate separate colliding streams of air which transport and mix the inhalable medium.

Abstract: The device, suitable for use in a hand roller, for transferring a film from a carrier tape to a substrate is a cartridge containing a feed reel and a windup reel. The tape travels by way of a protruding stiff applicator bar which has a pressure-applying edge for pressing the tape against the substrate. The stiff applicator bar is on a spring support member which can be deflected until a protrusion on the bar encounters a detent fixed on the housing. The application bar has its pressure-applying edge appropriately shaped to facilitate the transfer action.

Abstract: An applicator for adhesive film to a surface has a supply spool for tape carrying the film and a take-up member coupled to the supply spool by a drive mechanism. The tape passes around an applicator member which is resiliently mounted on the housing and can press the tape against the substrate so that the adhesive film is transferred to the latter.

Abstract: A hand-operated device for transferring a film from a carrier tape to a substrate has a housing made up of two parts connected by a swivelable linkage. The housing has two rotatable pivot pins coupled to each other by a clutch coupling. A cartridge is held in position in this housing by a suitable arrangement of pins and receptacles. This cartridge has, conrotatably linkable to the pivot pins, a feed reel and a wind-up reel for the tape, and has an applicator element at one end over which the tape runs and which is used to press the tape against the substrate for transfer of the film.
