The invention pertains to a device for the cooling of edible foams, where a cooling or freezing system for pre-freezing of the foam is directly outlet-connected to an aeration system, a motor driven extruder device designed as combined deep freezing and transport device is outlet-connected to the cooling and freezing system, in which the pre-frozen foam can be cooled down to storage temperature, and the aeration device, the cooling or freezing system and the extruder device are connected together by means of pipes. The device of the present invention is characterized in that the extruder device has at least one double screw system with two screws positioned parallel to each other with their rotational axes. The lands of the screws of the double screw system scrape against the inner cylinder mantle surface of the housing surrounding it. The threads of the second screw are centered between the threads of the first screw and an increased spacing of the rotational axes of the screws is created, so that the front side of the screw thread of the other screw facing the surface of the cylinder mantle of each screw, has a radial distance from it. The lands of the screws with the surface of the cylinder mantle of the screws and of the inner surface of the cylinder mantle of the housing .[.bounds.]. .Iadd.bound .Iaddend.an extremely flat screw channel.

The invention provides a power storage and supply method and system for a drilling rig. The system comprises a primary common direct current (DC) bus, at least one secondary DC bus, at least one bi-directional DC-to-DC converter connected between the primary common DC bus and the secondary DC bus, at least one motor group each connected to the secondary DC bus through a DC-to-AC inverter, and an Energy Storage System (ESS) configured to be charged by regenerative energy from at least one motor group and discharge power to at least one motor group through the primary common DC bus and the bi-directional DC-to-DC converter. The system may further comprise a bi-directional AC-to-DC converter between the primary DC bus and an AC bus, wherein the ESS is further configured to be charged by regenerative energy generated during lowering operation of a jacking system for the drilling rig, wherein the jacking system is connected to the AC bus.

A granular sorption material including a plurality of porous granules formed by buildup agglomeration for separation, especially absorption, of harmful gases, especially of SOX and/or HCl, from offgases of thermal processes. The granules containing greater than 80% by weight, and preferably greater than 95% by weight, of Ca(OH)2 and/or CaCO3 based on the dry mass. The granules having a dry apparent density ρ, determined by means of an apparent density pycnometer, of 0.5 to 1.2 kg/dm3, preferably 0.7 to 1.1 kg/dm3, and/or a porosity of 45% to 73% by volume, preferably 55% to 65% by volume, and have especially been increased in porosity. A process for producing the granular sorption material, in which pores are introduced into the granules by means of a porosity agent during the production.

Methods and systems for producing a change in a medium. A first method and system (1) place in a vicinity of the medium at least one upconverter including a gas for plasma ignition, with the upconverter being configured, upon exposure to initiation energy, to generate light for emission into the medium, and (2) apply the initiation energy from an energy source including the first wavelength λ1 to the medium, wherein the emitted light directly or indirectly produces the change in the medium. A second method and system (1) place in a vicinity of the medium an agent receptive to microwave radiation or radiofrequency radiation, and (2) apply as an initiation energy the microwave radiation or radiofrequency radiation by which the agent directly or indirectly generates emitted light in the infrared, visible, or ultraviolet range to produce at least one of physical and biological changes in the medium.
