Patent ES-8405533-A1 (ES)
Title: A multiprocessor system with at least three-level memory hierarchies.
IPC: G06F12/08
Filed: 1982-12-30
Abstract: A muitiprocessing three level memory hierarchy implementation is described which uses a "write" flag and a @ flag per pages of information stored in a level three main memory. These two flag bits are utilized to commmunicate from main memory (4) at level three to private and shared caches (12, 27 20, 30 14 22) at memory levels one and two how a given page of information is to be used. Essentially, pages which can be both written and shared are moved from main memory to the shared level two cache and then to the shared level one cache, with the processors executing from the shared level one cache. All other pages are moved from main memory to the private level two and level one caches of the requesting processor. Thus, a processor executes either from its private or shared level one cache. This allows several processors to share a level three common main memory without encountering cross interrogation overhead. If uniform status within a page cannot be guaranteed at the main memory interface, the shared cache configuration does not interface with main memory but, in parallel, with the private caches at an appropriate intermediate level.

Title: Plasma spraying of abrasive coatings
IPC: B05D7/24
Filed: 1983-05-12
Abstract: In the plasma spray deposition of an abrasive grit coating on a substrate, abrasive grit particles are injected into a high temp. plasma stream at a location downstream of the location at which matrix material particles are injected, in a direction 180 deg. apart at the plasma stream circumference from the direction of matrix particle injection and at a distance from the substrate such that the matrix particles and the grit particles come into simultaneous contact with the substrate surface and with each other. The plasma stream is traversed across the substrate. - Also claimed is the plasma spray deposition of a grit-contg. coating onto a narrow substrate, in which the substrate is offset from the plasma spray stream axis during coating to avoid the erosive zone at the axis of the spray. - The process is useful in the gas turbine engine industry, e.g., in the prodn. of interstage gas path seals between rotor and stator assemblies. Economical coatings with good adhesion and angularity of grit particles are achieved. DEAB- DE3317094 C Abrasive medium coating is applied to a substrate, partic. contact surface of a gas turbine, by using a plasma spray gun, in which a stream of plasma gases is produced within a plasma generator and directed on to the substrate. Particles of a matrix material are sprayed into the plasma stream remote from the substrate surface, while abrasive particles are injected into the plasma stream in the direct vicinity of the surface, particles of each constituent coming into contact with the surface at the time. Pref. particle injection of matrix and abrasive materials is displaced by about 180 deg. w.r.t. the plasma stream.

Title: Bone substitute material based on natural bone.
IPC: A61F2/28
Filed: 1984-10-19
Abstract: The bone substitute material on the base of natural bone is rendered completely free of albumin and antigen by premaceration, pyrolization and sintering and its frame work consists of only the natural mineral structure of the natural bone. In the process of production of this bone substitute material the bone pieces are submitted to a pretreatment with warm water for removing of the soft parts, subsequently takes place a dealbumination by means of a solution of 10 to 30% H2O2 in a shaking machine and a degreasing with ether. The bone pieces treated in this way are subsequently submitted to a combustion in a stove at 400 DEG C. to 1500 DEG C. and then to a sintering. This bone substitute material which may exist in the shape of the bone part to be replaced forms a form stable matrix for the bone regeneration in which only pure "mineral bone" is present so that no immunogen reactions can take place. The process which includes combustion and sintering is considerably shorter than known processes.
