Patent ES-8302499-A1 (ES)
Title: Process and apparatus for pressure casting fusible metals.
IPC: B22C9/06
Filed: 1982-01-19
Abstract: The die-cast pieces are cast in a mold shell (4, 5) of a metallic material having a high heat conductivity. A refrigerating chamber (8) is connected to the shell. A refrigerating agent cools down the shell to the temperature of withdrawing from the mold. The refrigerating agent can be preheated and compressed to a pressure greater than the air pressure and during the cooling it can be vaporized. In order to obtain the greatest freedom in the choice of the solidification direction, the melted metal is supplied from a cavity avoiding a heating of the mold and the thinwalled shell of the mold is heated by the metal at a temperature close to the temperature of withdrawing from the mold. In the cooling phase during the filling of the mold, the vaporization of the liquid refrigerating agent takes place on the outer walls of the thin-walled shell.

Title: Oral prosthesis and method for producing same.
IPC: A61K6/884
Filed: 1982-07-01
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. A porous implant (31,41) may be used for jaw bone replacement in order to improve the fitting of dentures.

Title: Wet granular material drainage feed - has base which forces hot gas through unsaturated portion of material pile
IPC: F26B5/00
Filed: 1982-07-27
Abstract: The drainage feed is for wet granular phosphate after mining and washing.

Title: A brake assembly.
IPC: B60T13/567
Filed: 1984-11-22
Abstract: A brake assembly (10) having a master cylinder (12) attached to the front shell (14) of a power assist apparatus (16). The front shell (14) is connected to a rear shell (20) which in turn is fixed to a stationary member (22). The front shell (14) has a conical section (70) that extends toward and partially surrounds the master cylinder (12). A movable wall (82) located between the front (14) and rear shell (20), which is substantially concentric to the front shell (14), divides the interior thereof into a front chamber (96) and a rear chamber (97). The movable wall (82) is connected to operational pistons (32, 34) within the master cylinder (12). An annular projection (98) extends through an opening (142) in the rear shell (20). A cylindrical member (154) located in the opening (142) extends into the rear chamber (97). A return spring (92) urges the movable wall (82) toward the cylindrical member (154). The position of the cylindrical member (154) is adjustable to align the pistons (32, 34) in the master cylinder (12) and thereby permit fluid communication from a reservoir (38) to the master cylinder (12) through compensator ports (40, 42). A bearing member (150) which surrounds the annular projection (98) has a resilient portion (148) that engages the annular portion (98) to seal the chamber (97) from the surrounding environment. In response to an input signal, a pressure differential is created across the movable wall (82). This pressure differential produces an output force which moves the pistons (32, 34) past the compensator ports (40, 42) to develop an operational fluid pressure for effecting a brake application. The conical section (70) of the first shell (14) reacts to reduce any axial deflection that may be created by the output force.
