IPC: A01D78/12
Filed: 1985-08-09
Abstract: The haymaking machine consists of rakes (22) provided with tines (37).

Title: Shaped ceramic composites and methods of making the same
Inventor: NEWKIRK MARC S
IPC: C04B35/65
Filed: 1987-05-08
Abstract: A method of producing self-supporting ceramic composite bodies of desired shaped by infiltrating a permeable preform with polycrystalline matrix material consisting essentially of an oxidation reaction product obtained by oxidation of a parent metal precursor, such as aluminum, and optionally containing therein metallic constituents. The composite body is formed by contacting a zone of a permeable preform, having at least one defined surface boundary spaced from said contacting zone, with a body of molten metal which is reacted with a suitable vapor-phase oxidant to form an oxidation reaction product. Within a certain temperature region, and optionally with one or more dopants in or on the parent metal or said permeable preform, molten parent metal migrates through previously formed oxidation reaction product into contact with the oxidant, causing the oxidation reaction product to grow into the preform toward said defined surface boundary so as to infiltrate the preform up to said defined surface boundary, and provide the composite structure of desired geometry.

Patent PT-94739-A (PT)
Inventor: KANTNER ROBERT CAMPBELL
IPC: C04B35/65
Filed: 1990-07-17
Abstract: The present invention relates to a novel process for forming macrocomposite bodies. Particularly, a suitable matrix metal (33), typically in a molten state, is in contact with a suitable mass of filler material or preform (31) located adjacent to, or in contact with, at least one second material in the presence of a suitable reactive atmosphere in an impermeable container (32), at least at some point during the process, which permits a reaction to occur between the reactive atmosphere and the molten matrix metal (33) and/or mass of filler material or preform (31) and/or impermeable container (32), thereby causing molten matrix metal (33) to infiltrate the mass of filler material or preform (31) due to, at least in part, the creation of a self-generated vacuum. Such self-generated vacuum infiltration occurs without the application of any external pressure or vacuum. The molten matrix metal (33) infiltrates the mass of filler material or preform (31) to such an extent that the molten matrix metal (33) contacts at least a portion of the at least one second material. Upon cooling the matrix metal (33) to a temperature below the melting point of the matrix metal, a macrocomposite body is formed comprising a metal matrix composite body bonded to at least a portion of the at least one second material.

Date Jul. 11, 1991.When dispensing carbonated beverages, particularly beer and draught stout, it is desirable to obtain a close-knit creamy head. This contributes to a creamy taste and adds considerably to the customer appeal. To obtain this effect when dispensing from a can (1) it includes a lid (2) having a secondary compartment (4) formed on it and a non-resealable closure (3) in communication with the secondary compartment. At least one orifice (5) extends between the secondary compartment (4) and the inside of the container (1), and a liquid (8) is held in the secondary compartment. The container is arranged so that on opening of the closure (3) the pressure in the secondary compartment (4) is reduced to atmospheric with the result that gas or liquid from the main body of the container (1) is jetted through the at least one orifice (5) into the liquid (8) in the secondary compartment (4) to generate a foam in the secondary compartment. Complete opening or removal of the closure (3) enables the contents of both the secondary compartment (4) and the remainder of the can (1) to be mixed and dispensed together so that the foam produced in the secondary compartment acts to seed the generation of small bubbles throughout the beverage (8) in the can (1).

Title: Method for the determination of the mobility of current carriers by a hall sensor
Inventor: RUMENIN CHAVDAR S
IPC: H01L43/06
Filed: 2001-12-17
Abstract: The method can be used in microelectronics, in sensors and microsystems, in instrumentation enginering, in the science of materials, etc. It is simplified, improves the precision amd requires no preliminary mode approximations. The method is based on a thre-probe parallel-magnetic field Hall-configuration operating in the current regime of Hall. The specific resistance and the Hall factor are dtermined in advance on the classical Hall sensor with G-factor equal to 1, expressed by scribing from the semiconductor wafer in which the mobility of the current carriers shall be determined. Mobility is determined by the information received in this way. By the expression for the Hall current of a three-leads probe configuration the G-factor is calculated based on experimental results, and not mathematically based on approximations. The mobility of the current carriers on any other semicionductor wafer can be determined. 1 claim, 1 figure

Title: System for photodynamic therapy in oncological diseases
Inventor: GIZBREHT ALEKSANDUR
IPC: A61N5/067
Filed: 2006-05-12
Abstract: The system for photodynamic therapy in oncological diseases, malignant dermatologic diseases in particular, is applicable in medicine. It comprises two independent laser sources with different wavelength (1 and 2) combined with light guides (3), a heat source (4), and a heat sensor (5). During therapy, photosensibilizer solution is preliminarily introduced into the patientÆs organism, which gets concentrated in the malignant formation. This is followed by heating the formation and the area around it with a heat source up to a temperature of 42-43 degrees, which is kept permanent, and simultaneous irradiation by the two laser sources during therapy. The wavelength of one of the laser radiations ensures the maximum absorption by the photosensibilizer leading to the photochemical reaction with the formation of the syngletic oxygen. The second wavelength used in combination with the heat action stimulates further the creation of the molecular oxygen in the area. The quantum yield of the therapy process is raised up to approximately 18 percents.
