Title: Oral prosthesis and method for producing same.
IPC: A61K6/884
Filed: 1981-12-02
Abstract: A porous implantable oral prosthesis which can be used to replicate and replace any hard tissue portion of the mouth such as bone and teeth is described. The prosthesis comprises sintered polymeric particles coated with a hydrophilic material. The polymeric particles vary in size to as to provide an area of relatively coarse porosity (2,12,22,32,42) where the porsthesis is intended to interface with bone tissue (6,16,26,38,48) and relatively fine porosity where it is intended to interface with soft tissue (7,17,27,39,47). A process for producing such prosthesis by filling a mold with appropriate molding compounds comprised of polymeric particles and a hydrophilic monomer, sintering the particles and polymerizing the monomer by dielectric heating, removing the sintered material from the cooled mold, and placing the prosthesis in a hot liquid to remove residues is described. An entire tooth, including a nonporous crown (4,14) may be produced. A process for producing a porous replica of a tooth root (1) suitable for implantation immediately after extraction of a tooth is disclosed. When extraction has taken place in the past and has resulted in the bone and gum receding, a porous implant (11,21) inserted in a newly drilled hole in the patient's jaw bone may be used. A central post (5,15) associated with the implant projecting above the gum may be used for attachsing a denture, partial bridge or a crown.

Patent ES-8302551-A1 (ES)
Title: Identification card and method of producing it
IPC: B42D25/415
Filed: 1981-12-23
Abstract: An identification card, in particular an all-plastic indentification card, written on by means of a laser, having user-related and user-neutral data such as a name, account number, etc. present on the surface of the indentification card in the form of local discolorations of the identification card material without any transition. Due to a local increase in tensile strength, these decolorized areas have greater resistance to mechanical changes and/or chemical solvents than the surrounding areas of the identification card made of the same identification card material. Thus attempted falsification by means of mechanical and chemical means is prevented in an especially effective way, since such attempts lead to destruction of the identification card in each case. The personalization of the identification card with the freely selectable user-related data can take place by preference decentrally by means of a laser beam, the energy of which is controlled in such a way that the identification card material is decolorized but not destroyed.

Patent ES-8308384-A1 (ES)
Title: Position control mechanisms for vehicle ignition locks.
IPC: F02D11/02
Filed: 1982-08-27
Abstract: The ignition lock includes a lock cylinder mechanism (16), mounted on the steering column, which operates an ignition pin (18) sliding in a guide housing (20). A lock recess (24) in the ignition pin accommodates part of a latching ball (26) disposed in an opening (28) in the housing, except when the pin is moved to a lock position (L) by the lock mechanism. A floor-mounted gearchange lever (36) is coupled by a cable (34) to a transmission shift pin (32) sliding in the guide housing. The ball (26) can not be accepted in the recess (24) until the ignition pin is moved from the locked position. However if the transmission shift pin (32) is in a position other than the park (P) the park recess (38) does not accommodate the latching ball. As a result the ignition pin, and therefore the ignition lock, can not be set to the locked position.

Title: Apparatus and method for clarification of water using combined flotation and filtration processes
IPC: C02F1/52
Filed: 1982-09-10
Abstract: Apparatus and a method for removing suspended particles from water in a circular tank having a distribution and flocculation chamber immersed in the tank of water and carried circularly around the tank by a carriage. Flocculating material and inlet water are introduced into the body of water from the moving flocculating chamber at the same rate as clarified water is discharged through a filter substantially covering the bottom of the tank. A majority of particles in the water is collected by flocs in the water and floated to the water surface by air bubble action. The floating sludge is removed by a spiral scoop carried by the carriage. The water is then passed through the bottom filter which removes the remaining flocs completing the clarification of the water for discharge. Apparatus is provided for selectively back washing sections of the filter while the remainder of the filter is in operation.

Title: Serial flow continuous separation process.
IPC: B01D15/18
