Title: Process for producing composed selfcarrying ceramic product
Inventor: KENNEDY CHRISTOPHER ROBIN
IPC: C04B35/65
Filed: 1987-12-15
Abstract: The present invention provides a method for producing a self-supporting ceramic composite by the oxidation of a parent metal (10) to form a polycrystalline ceramic material consisting essentially of the oxidation reaction product of the parent metal (10) with an oxidant, including a vapor-phase oxidant, and, optionally, one or more metallic constituents. A permeable filler material, such as a preform (14), with at least one surface bearing a permeble stratum (18), is contacted with a body of molten parent metal (10) heated to a temperature above its melting point but below the melting point of the oxidation reaction product. At least a portion of the oxidation reaction product is maintained in contact with and between the molten metal (10) and oxidant to transport the molten metal through the oxidation reaction product toward the permeable stratum (18) and into contact with the oxidant so that the oxidation reaction product continues to form at the interface between the oxidant and previously formed oxidation reaction product that has infiltrated the filler material. The reaction is continued to infiltrate at least a portion of the stratum (18) with the oxidation reaction product and to produce an intermediate ceramic body having an adjacent ceramic composite overlaid with a ceramic stratum. The ceramic stratum is removed from the underlying ceramic composite to produce a self-supporting ceramic composite having the surface established by the permeable stratum (18).

Title: Locking/release bracket for closing/opening automatically and totally the roofing of tunnel greenhouses
Inventor: IMBESI SAVERIO
IPC: A01G/
Filed: 1990-09-20
Granted: 1994-03-04
Abstract: With the locking/release bracket according to the present invention it is possible to open automatically and totally the roofing of a tunnel greenhouse in such a way that the said roofing is collected on a tube rotating on itself. This rotating tube, when it rotates upwards, travels over the bracket, thereby totally opening the roofing, whereas, when it rotates downwards, it closes the roofing, the tube remaining locked in the special seating formed in the locking/release bracket. The opening and closing movement is controlled electrically by a motor which is located in the centre or at the end of the tunnel greenhouse and which, upon receiving a signal from a sensor or as a result of manual operation, for the purposes of temperature, wind, luminosity, rain or humidity, closes and opens the roofing. <IMAGE>

Title: Method for assessment of sympathetic reflectory activity under general anaesthesia caused by laryngoscopy and endotracheal intubation
Inventor: JAKUSENKO NATALJA
IPC: G01N33/50
Filed: 2010-03-01
Abstract: An invention refers to the field of medicine and can be applied for assessment of patient's sympathetic reflectory activity under general anaesthesia caused by laryngoscopy and endotracheal intubation as well as for evaluation of adrenergic reaction caused by some devices used in anaesthesiologic and intensive therapies. The method offered includes the following consecutive steps: dilution of the patient's saliva by a solvent which has a similar osmolarity to that of the saliva; dilution by the solvent which has a similar osmolarity to that of the saliva of the second salivary sample obtained from the patient's mouth1-3 min. after intubation,the precipitation of the cells in the diluted salivary samples, alfa amylase detection in the salivary samples by Phadeba method, comparison of alfa amylase level before intubation and after it. If the alfa amylase level after laryngoscopy or during endotracheal intubation is higher than before it, one can find the patient's sympathetic reflectory activity to the specific intubation device.

Title: A method of thermal conductivity measuring
Inventor: PALCEVSKIS ERIKS
IPC: G01N25/18
Filed: 1998-03-06
Abstract: This invention can be applied mainly in the measurement and control over thermal conductivity of solid bodies (such as metals, ceramics, glass, plastic) possessing a good thermal conductivity (higher than 10 W/mK). It is based on the rule of thermal physics determining the relation between the thermal conductivity of a material and the temperature gradient in the sample, which emerges, if a certain and constant heat flow is carried through it.The goal of the invention is to simplify the measuring procedure, ensuring equivalent heat flow for different samples, regardless of their thermal conductivity, dimensions, and geometrical form, while under the same measuring conditions.The principle of the invention: the heat flow is provided or drained through a thin layer, possessing low thermal conductivity. The thickness of the layer is chosen in such a way that its resistance to the heat transfer (the relation between the thickness and the thermal conductivity) is at least ten times larger than for the tested sample.
