Title: Method for production of landfill gas
Inventor: BLUMBERGA DAGNIJA
IPC: C02F11/14
Filed: 2015-02-20
Abstract: The present invention relates to the field of energetics, particularly to energy production and waste management sectors. It is provided to use for high methane content gas production from landfills. According to the described method, with a view to increase the production amount and quality of landfill gas, hydrogen is injected into municipal waste landfill. Hydrogen is produced in electrolysis process using electricity from solar panels on the covering of landfill. According to the invention there is provided tubing system for introducing produced hydrogen gas (H2) into landfill. In such way production amount and quality of landfill gas are improved on the ground of increasing methane content to 70 %. The solar panels on the surface of landfill and uses of electric energy produced by them allows to avoid additional use of non-renewable natural sources or landfill gas produced as end-product by mentioned apparatus. It is not necessary to obtain hydrogen somewhere outside of landfill area.

Title: Out-of-step regime control method
Inventor: SAUHATS Antans
IPC: H02H7/26
Filed: 2016-12-14
Abstract: The invention object relates to high-voltage electrical networks and power plants, in particular to the methods of controlling out-of-step conditions of asynchronous generator. The out-of-step control method is based on the equal area criterion and is particularly is suitable for the case when the pre-fault configuration of the electrical network is restored as a result of successful transmission line auto-reclosing. In the implementation of the proposed method, the theoretically possible generator's rotor deceleration energy is taken into account, which may appear due to the restoration of the electrical network configuration.

Inventor: SAUTEBIN RAOUL
IPC: B22D11/16
Filed: 1982-11-18
Abstract: The cooling of a continuously cast ingot of metal as it emerges from the mold is carried out by applying coolant directly to the ingot surface. In order to reduce the amount of curvature at the foot of the ingot due to too rapid cooling, a substance which releases a gas as a product of decomposition on striking the hot ingot surface is added to the coolant at least during the initial phase of casting. This gas forms an insulating film on the ingot surface thus reducing the rate of heat extraction. Particularly suitable for this purpose are substances which produce carbon dioxide or nitrogen as decomposition product.

Title: Method and apparatus for compressing gas
Inventor: ALLAM R
IPC: F01D15/08
Filed: 1982-06-17
Abstract: The fuel required to provide the energy for compressing a gas can be reduced by compressing the gas substantially adiabatically through a pressure ratio of at least 2.5:1 in a compressor, cooling the hot compressed gas by heat exchange with water at superatmospheric pressure, further heating the water to produce super-heated steam and using the superheated steam to drive the compressor. The total amount of fuel consumed can be considerably less than that used for compressing gas conventionally (i.e. substantially isothermally).

Title: A packing container blank, a method for the manufacture of the same and a packing container made from the blank
Inventor: BILLBERG ALF
IPC: B65D5/06
Filed: 1982-08-04
Abstract: Packing container blanks for gable-top packages are cut out of a material web which, up to now, has caused an appreciable amount of waste material, since the edges of the blanks are irregular and cannot be "dovetailed" into one another. A packing container blank is provided with partly straight, parallel lateral edges (11,12), and partly transverse edges (11,12) which are indented according to a regular pattern which is repeated over the width of the blank. As a result of the indentations, the edges of the blanks too can be formed without wastage.

Title: Coating material for lenses
Inventor: PERKINS PETER GRAHAM
IPC: C08J7/04
Filed: 1985-05-24
Abstract: A material particularly used for protecting a lens surface against scratching comprises a solution containing nitrocellulose in solvent the nitrocellulose being present in the solvent in the range 2.5% to 3.8% by weight. When the material is applied to a lens a coating adheres to the lens in which nitrocellulose is the principal constituent. This coating protects the lens against scratching during manufacture and enables traditional manufacturing processes to be applied for identifying and marking the focal centre of the lens blank prior to shaping the periphery of the blank because the coating does not disguise the optical properties of the lens.

Title: Process to ultrapurify liquid nitrogen imported as back-up for nitrogen generating plants
Inventor: KAMRATH DAVID J
IPC: F25J3/04
Filed: 1990-05-11
Abstract: In a nitrogen generation process in which a stream of air is compressed in compressor 11, is cooled and has water vapour and carbon dioxide removed therefrom in a reversing heat exchanger 16, and is separated in a rectification column 24, a gaseous nitrogen product stream 30 is produced. An air turbine 22 is operated to produce refrigeration for the process. The process is also used to purify merchant liquid nitrogen typically containing from 0.5 to 5 vpm of oxygen. A stream 51 of such merchant liquid nitrogen is introduced into a stage of the rectification column where the liquid nitrogen has a substantially matching composition. A stream 36 of purified liquid nitrogen is withdrawn from the top of the column 24. The purified liquid nitrogen can be produced at a rate in excess of that made possible by the turbine 22 without reducing the efficiency of gaseous nitrogen generation.
