Inventor: WOLFF HEINZ SIEGFRIED
IPC: F03G7/06
Filed: 1988-09-30
Abstract: A fire sprinkler (1) has a flow passage (3) for water or other extinguishing fluid closed by a frangible body (4), which may be a simple disc. A separate mechanism reponsive to temperature-rise conditions shatters the frangible body (4), and the fluid then flows from the passage (3) to impinge on a distributor (5) (as in conventional sprinklers). The shattering mechanism is preferably actuated by a shape-memory alloy, preferably in sheet form (11), which can be located below the distributor (5) for maximum exposure to radiant as well as convective heat; it can also be thermally insulated, contributing further to speed of response.

Title: Process for production of compensational polymeric layer for lcd optical switches and construction of such switch
Inventor: PIRS JANEZ
IPC: C09K19/00
Filed: 1999-06-15
Abstract: The proposed invention is solving a technical problem of compensation of the angular dependence of contrast for optical devices with liquid crystal displays (LC optical switches operating on the principle of electrically controlled optical birefringence) by means of a compensational layer exhibiting a negative optical birefringence which enables optical compensation of the angular dependence of birefringence of the LC layer in the state where the LC molecules are arranged homeotropically (a typically optically positive birefringence). The procedure of manufacture of the optically negative birefringence compensational layer is based on a controlled spontaneous deformation of polymeric molecules during the polymerisation process. The procedure is made possible by using known and well-controlled technological processes and enables a mass production of compensational layers to be carried out. The invention is solving both the process of manufacture of a compensational layer with the required optically negative birefringence and the construction/manufacturing procedure of the optical switch using such a compensational layer.

Title: Process for industrial composting of agricultural solid residential wastes and treated mushroom compost for the production of organic fertilizer-compost by the "windrow" system
Inventor: DOJCHEVA MARIYA
IPC: C05F17/00
Filed: 2003-12-19
Abstract: By the process fruit and vegetables can be grown using organic fertilizer-compost without any residual nitrites and nitrates. The separation of the farm residues in nitrifying (those who contain organic nitrogen) and carbonizing (which contain large quantities of organic carbon) and their alternation in specific layers in arranging a large pile ensures C/N ratio of 20 - 25/1. According to the process soil as a layer in the large pile is used, by which the wastes and the compost containing soil microflora, participating in the composting, are enriched. In this way the stress condition of the ecological systems in the soils is prevented after their application with fertilizer-compost. On a cement site with shafts the water soluble organic and inorganic nutritive substances are stored from the wastes and are injected back to the dry wastes. By using a polyethylene cover the fermentation process is accelerated and the volatile substances are not allowed to get into the environment, such as carbon and nitrogen, in the form of oxides. The cover also prevents the product and the wastes of the atmospheric effects (such as rain, snow, wind and sunshine) and the organic fertilizer-compost does not evaporate.
