Title: Actuating installation for access doors of railway passenger cars
Inventor: LAZAR LULARIU NICOLAE
IPC: B61D19/02
Filed: 2000-02-16
Abstract: The invention relates to an actuating installation for the access doors of railway passenger cars, namely to an electric-pneumatic actuating installation for railway car doors of the revolving-folding type and improves the invention disclosed in the Application 99-00865. The claimed installation comprises a breaking flow controller (8) mounted in counter pressure in the closing branch to prevent the shocks at the end of the opening stroke. A power cylinder (1) is employed in order to improve the operation at the end of the closing stroke and at the beginning of the opening stroke, said cylinder (1) being provided by the manufacturer with a proximity sensor (9), normally closed, and a magnet located on the piston, the locking of the inner handle (10) being prevented by means of a single acting cylinder (11) mounted in the inner escutcheon (12) of the access door by means of a holder (13). A pin (14) is secured at the end of the rod of the single-acting cylinder (11), a seat (a) cut in the axle of the handle (10) accomodating said pin (14) when an electrically operated locking valve (15) receives the command to supply the single-acting cylinder (11) with compressed air.

Title: Process for burning fuels of low caloric power
Inventor: IVANESCU LILICA
IPC: F27B9/10
Filed: 2003-04-10
Abstract: The invention relates to a process for burning fuels of low caloric power, such as blast-furnace gas. According to the invention, for 100% burning this gas, there is used air enriched with oxygen, the oxygen ratio x in the air depending on the fuel chemical composition, the caloric power Hi thereof, the share of [CO], [H2], etc. of the chemical components and the burning temperature, according to a relation of specific dependence for burning optimization: (see the claim formula) where - lamda is the air excess coeficient, eta is the burning efficiency and cga is the gas specific heat.

Title: Process for preparing fuel briquettes
Inventor: STR ETUL E COSTIC E
IPC: B27N3/06
Filed: 2003-05-23
Abstract: The invention relates to a process for the utilization of wood waste as sawdust resulting from cutting or processing wood mass, as a solid fuel, which may be burnt for producing the thermal energy used with in the thermal consumption. According to the invention, the process consists in mixing the sawdust taken in the ratio of 60 ... 90 % by mass in a mixer at a temperature ranging from 50A to 120A C, preferably from 70 to 90A C, with 10 ... 50 % black fuel oil or other petroleum residue, to which petroleum or coal coke or coal dust products with caloric value are added in a ratio of 0 ... 20 % by mass, followed by briquetting the resulting mixture into regular geometric shapes of various sizes, in cooling to the room temperature, resulting a solid fuel with a caloric value of 4,000 ...5, 600 kcal/kg.
