摘要:
Removal of SO.sub.2 and NO.sub.x from combustion flue gases is effected to be subjected to irradiation by an electron beam and to the action of microwaves applied in the form of a continuous and/or pulsed stream. The stream of flue gases irradiated by the electron beam in the radiation zone is subjected to the action of microwave energy in the whole cross section of the stream of the flue gases. This results in a decrease in the dose rate "average power of the electron beam" and a reduction in the costs of accelerators while retaining the same removal efficiency. Further, the apparatus for removal of SO.sub.2 and NO.sub.x from combustion flue gases is provided in a radiation process in which a stream of accelerated electrons and microwave energy are used simultaneously.
摘要:
An elastomeric shock absorber having enhanced damping characteristics comprises a casing filled with a compressible elastomer; a piston rod immersed in the elastomer; a piston head mounted on the piston rod and the piston head is provided with connecting ports communicating with the front and back spaces of the piston and is also equipped with a mobile member. The mobile member is located between a surface from which the connecting ports emerge as well as a ring or like stop block. The stop block is mounted on a section of the piston head facing a flow chamber, wherein the piston head moves into and out of an outer cylindrical surface of the casing and wherein at least one groove is provided on an inner surface of the casing, which together with the outer cylindrical surface of the piston head form a flow chamber shaped as a solid of revolution, the solid of revolution being selected from the group comprising a cone, a ring, a torus and any combination thereof.

The invention improves performance characteristic of coupler arrangements; and embodies a cushioning device (8) which comprises an elastomeric shock absorber (9) whose bottom part (10) is held in a rear stop block (12) supported on a rear stop (7, 7'). The opposite section of the elastomeric shock absorber is slidably mounted in the casing (13) which includes a guide (14) closed by a fixedly attached front stop block (15), with the stop block abutting the front stop (6, 6'). Inside the casing the stop block abuts the piston rod (16) of the elastomeric shock absorber.
