Relatively high speed methods for increasing the bulk density of coal particles, apparatus for increasing the bulk density of coal particles and methods for making metallurgical coke. Once such method includes depositing coal particles onto a charging plate external to a coking oven to provide an elongate bed of dry, uncompacted coal having an upper surface of the charging plate. The charging plate has side walls, and at least one movable end wall An impact pressure is applied to the upper surface of the bed of dry, uncompacted coal while degassing the coal to provide a dry, compacted coal bed having a bulk density ranging from about 960 to about 1200 kilograms per cubic meter.

A system and method for determining characteristics of a multiphase flow in a well / pipe are disclosed. The disclosed system and method use an optical immersion probe including a flow gap across which two or more types of radiation are transmitted in order to measure absorptions of two or more substances within the multiphase flow. Primarily, broadband ultraviolet (UV) and / or near infrared radiations (NIR) are utilized with the probe to gather absorption data at and / or around at least one of the water peaks and at and / or around one or more oil or oil-condensate peaks. This data may be utilized to calculate the water-cut of the multiphase flow over a wider range of gas volume fractions. Additionally, pressure ports having pressure sensors being located on the optical immersion probe for determining the impact pressures and flow rates of different phases of the multiphase flow may also be used.

A method for controlling rock drilling and a rock drilling arrangement having at least one feed channel of a feed actuator provided with a restrictor, which causes a pressure drop if the penetration rate increases and, consequently, a flow through the restrictor increases. A pressure difference and an increase in the penetration rate can be detected by sensing the pressure before the restrictor and after the restrictor. When the feed rate increases, a hydraulic system is arranged to decrease percussion pressure.

A damping device for a handgrip of an object includes a bladder disposed in said handgrip, an inflation device in fluid communication with the bladder, and a controller adapted to detect at least one of vibrations and impact pressure, and automatically adjust a cushion pressure of said bladder by causing the inflation device to inflate or deflate the bladder with a fluid as appropriate in order to attenuate the at least one of vibrations and impact pressure transmitted through said handgrip.

The invention discloses a magneto-rheological damping tuned damper for super-high-rise buildings. The magneto-rheological damping tuned damper for the super-high-rise buildings mainly comprises a magneto-rheological tuned mass block, a leaded steel lamination damper, a rigid force transmitting plate, a floor embedded steel plate, a field regulator, a floor and a building main body framework. The magneto-rheological tuned mass block is adopted as a variable-damping tuned mass damper. The working principle of the magneto-rheological tuned mass block is that a plurality of resistance reducing sliders are arranged in the magneto-rheological tuned mass block, and the resistance reducing sliders slide in magneto-rheological fluid to eliminate shock of the super-high-rise buildings caused by earthquakes or strong wind; and the outer portion of the magneto-rheological tuned mass block is connected with the leaded steel lamination damper for reducing impact pressure of the magneto-rheological fluid on the structure. The damper has the advantages of good structural force performance, easy implementation, good stability, good shock absorption effect, good safety and the like. A magneto-rheological system has low power consumption, small size and obvious shock absorption effect, and is beneficial to greatly reducing the cost of the tuned mass dampers for high-rise buildings, super-high-rise buildings and tall structures.
