Publication number: 20140198601Abstract: The present invention relates to a device for producing a hardenable mass, preferably bone substitute and/or bone reinforcing material or bone cement or similar material. A mixing container (3) has a mixing space (4) in which at least one powder and at least one liquid component (5, 6) are mixed to provide the hardenable mass (2). A piston means (7) is provided in the mixing space (4) of the mixing container (3). At least one means (8) which is rotatable relative to the mixing container (3) cooperates with the piston means (7) for, in a retaining position (P1), retaining said piston means (7) relative to the mixing container (3) and, by rotation to a release position (P2), releasing the piston means (7) such that said piston means can move in a direction (U) towards at least one opening (49) through which said mass (2) can pass out of the mixing space (4).Type: ApplicationFiled: January 16, 2014Publication date: July 17, 2014Applicant: Bone Support ABInventors: Lars LIDGREN, Sven JÖNSSON, Torgny LUNDGREN, Östen GULLWI, Fritz BRORSSON

Patent number: 8388783Abstract: The present invention relates to a method for manufacturing a hull for vessels, containers or equivalents. The method comprises the steps: preparing an elastic or viscoelastic glue through mixing of at least two components; monitoring and/or controlling the mixing for determining if a correct desired mixing product has been achieved; applying a layer of the glue onto the hull (2) or on a first side of a sheet (4) of cellular plastic or other light weight material; mounting the sheet onto the hull, the sheet being equipped with a multiplicity of through-going air evacuation holes (12); placing an air permeable material (6) on top of the other side of the sheet (4), mounting a vacuum foil (8) onto the other side of the sheet; gluing by vacuum suction; observing visually if the glue exits out of the air evacuation holes on the other side of the sheet.Type: GrantFiled: February 20, 2009Date of Patent: March 5, 2013Assignee: Fagerdala Marine Systems ABInventor: Sven Jönsson
