A hydrostatic support structure wherein, to move a surface with a load disposed thereupon with respect to a bearing surface, a liquid cushion is provided due to a feeding of a liquid into an inner space defined by the bearing surface and a housing having a sealing member. Within the housing there is disposed a piston provided with its own sealing member which seals the gap between the housing and the piston, whereas the first sealing member defining the liquid cushion being formed along the perimeter of the inner space is rigidly secured to the housing of the support structure.

Hydrostatic support structure and liquid-cushion load-carrying apparatus

The apparatus comprises an explosion chamber made in the form of a tube closed at one end and accommodating at least one spark plug. The explosion chamber communicates with a chamber for preparation of an explosive mixture and with a batcher metering pulverulent coating material. The batcher includes a mixing chamber communicating with a hopper via a passage. The passage accommodates a device for controlling its cross-sectional area and is provided with a jet nozzle for positively feeding the coating material to the explosion chamber. A partition wall of a gas-permeable material is mounted within the hopper in equally spaced relation to the walls thereof to define an annular space communicating with a compressed gas source prevent self-compaction of the powder. A non-return valve is mounted in the portion of the batcher passage connected to the hopper to close the passage in case of back impact from the explosion chamber. This apparatus provides for more reliable cyclic batching of pulverulent coating material fed to the explosion chamber and is reliably protected against break-through of gas in case of back impacts from the explosion chamber as compared with conventional apparatus of the same type. This considerably improves the quality of coatings, especially when finely comminuted pulverulent coating materials based on refractory compounds are used.

The apparatus comprises an explosion chamber 1 in the form of a tube closed at one end and communicating through a discharge pipe with a powdered coating batcher while a safety pipe communicates it with a mixing chamber 9 which prepares the explosive mixture ignited in the explosion chamber 1 by a spark plug 21. Installed between the safety pipe and the explosion chamber 1 is a circular precombustion chamber 10 which surrounds said explosion chamber and communicates with its space through holes 11 in its walls 12. The end of the discharge pipe 5 mounts a jet nozzle 13 which is installed in the face of the closed end of the explosion chamber coaxially with the latter so that its outlet section 16 is arranged ahead of the holes 11 in the walls of the explosion chamber 11 relative to the open end 17 of the latter. Due to such an arrangement, the process of discharge of the explosive mixture from the precombustion chamber 10 through the holes 11 in the walls 12 of the explosion chamber 1 into the space around the nozzle 13 is accompanied by drawing in the powdered coating from the nozzle 13 and its intensive mixing with the explosive mixture which produces a homogeneous two-phase mixture and a more uniform coating and ensures a more economical operation of the apparatus due to a more rational utilization of the coating materials.
