A security barrier apparatus that includes a ground sleeve that is concreted into the ground at finish grade height and a uniquely configured jam member that is movable within the ground sleeve from a first free position to a second jammed position in engagement with the inner wall of the tubular sleeve. Connected to the jam member and extending upwardly therefrom is an elongated tension bar having an upper, internally threaded portion that is receivable within the hollow body portion of the apparatus. The jam member includes a tapered wall portion that is mateable with a tapered wall portion provided on the lower portion of the apparatus. A draw bolt extends through the cover of the ground sleeve and is adapted to threadably engage the upper threaded portion of the tension bar. Rotation of the draw bolt will cause the jam member to move upwardly within the ground sleeve in a manner to cause the tapered surface of the jam member to move into jamming engagement with the tapered surface of the ground sleeve securely locking the apparatus in place.

A surface acoustic wave arrangement has at least two interdigital transducers being provided on a piezoelectric substrate along an acoustic path, with at least one of the interdigital transducers being a fan transducer which is divided in a transverse direction into edge tracks and a center track. The acoustic wave excited in the edge tracks can be radiated either bidirectionally or unidirectionally in a predominant direction. On the other hand, the center track is formed so that the unidirectional radiation of the wave takes place in a direction opposite the predominant direction. In this manner, the signal transmission is suppressed in the frequency range corresponding to the finger period in the center track within the passband range of the transfer function. The obtained notch in the transfer function is used, for example, in receivers of terrestrial and satellite-based signals for suppressing the terrestrial signals in the satellite path of the receiver.

Cryogenic fluids are used to remove contaminants such as hard scale deposits from heating and/or heat transfer equipment. The fluid may be cryogenically cooled to achieve a liquid phase and/or a mixture of liquid and gas phases. The fluid may also be pressurized. The mixture does not include a solid phase. A particle injection port is not required. The cryogenic fluid contacting the surface of a scale or other contaminant that has built-up during service of heating or heat exchanging equipment causes a near instantaneous contraction at the scale surface. Cracks form at the scale surface contacted by the cryogenic fluid. These cracks extend through the scale thickness to the underlying material of the equipment of the heating and/or heat exchanging component. The fractured surface scale separates by spalling or de-cohesion from the underlying equipment structure and is moved off the surface by the action of the exiting cryogenic fluid.

The invention relates to a sunlight type greenhouse for attenuating heat by refraction, belonging to the technical field of facility agriculture. The sunlight type greenhouse is characterized in that a louver system which can be automatically adjusted is arranged on a transparent ceiling of the greenhouse; louver boards can be synchronously adjusted to the same angle; each louver board is made of a metal board (such as aluminum boards) so as to strengthen the heat absorption and heat dissipation effects; heat absorption coatings are coated at two sides of the metal boards; and surfaces of the metal boards are processed into mirror surfaces. When heat is to be attenuated, the louver system is adjusted so that the sunlight entering the upper surface of the louver boards is refracted onto the lower surface of adjacent louver boards and then refracted into the greenhouse. Through the louver system, most of the heat is separated outdoors and enough illumination can be obtained indoors at the same time, so that the sunlight type greenhouse is simple and practical in design, reliable, durable and easy in maintenance.
