A tubular article with circumferential projections having radial or chordal corrugations. The chords have tooth-like formations or are parallel and directed vertically in underground installation. In the last case, the sides of the tube can be devoid of the corrugations, or have them radially or tooth-like. Furthermore, the projections can be skewed and alternating in the opposite directions. Also, the projections can have offset planes. Finally, in case of two corrugations, they are diametrically opposed in a single chordal direction and are represented by rings bent parallel to the applicable load which is adverse with thus prestressed projections.

Hollow article with zigzag projections

A nozzle with a stand-off plate is incorporated in a hydrocyclone to break-down and remove contaminants existing within a liquid medium, said plate sloping towards the nozzle and abutting upon a cylinder forming the hydrocyclone.

Contaminants breaking and separation

A nozzle with a stand-off plate is incorporated in a filter to remove and break-down contaminants existing within a liquid medium, said filter being represented by a collar with a plurality of minor openings or by a spring.

Contaminants filtering and breaking

A towable wheeled undercarriage for carrying and supporting heavy loads and more particularly a carriage for supporting a crane of heavy duty or high capacity type. The carriage or carrier has a plurality of front and rear wheeled units independently mounted on a structural frame extending longitudinally of the vehicle and with at least the front wheels thereof being steerable. A gooseneck extends forwardly from the carrier and a coupling means on the forward end thereof connects to the fifth wheel of a tractor or towing vehicle. The coupling includes cushion means to support variable loads imposed by the fifth wheel on the gooseneck during towing and a linkage assembly is provided which is controlled by the fifth wheel to steer the front steerable wheels.

Steering assembly for towed vehicles

A towed vehicle includes a frame, front and rear ground-engaged wheel assemblies mounted along said frame in such a manner that the center of gravity of said vehicle is situated between said front and rear wheel assemblies, and a gooseneck secured to said frame and projecting therefrom. A fluid pressure suspension cylinder is secured to the gooseneck adjacent the free outer end thereof and has a plunger reciprocally mounted therein and projecting downwardly therefrom. A plate with a king pin is secured to the plunger for coupling with the saddle of a fifth wheel on a towing vehicle. The plunger in the cylinder acts in conjunction with a compressible medium, to cushion loads between said gooseneck and towing vehicle. The fifth wheel by way of linkages from a collar rotatably mounted on the cylinder, steer steerable wheels on the towed vehicle.

Towed vehicle with means for connection to fifth wheel of a towing

A steerable suspension assembly for a vehicle comprising a fluid pressure cylinder adapted to be secured to a rigid frame portion of a vehicle and having a plunger reciprocally mounted therein and projecting downwardly therefrom. The plunger and cylinder are arranged co-axially with the plunger freely rotatable in the cylinder about such axis. A jacket is mounted on the cylinder for rotation about the axis thereof and interconnected with the plunger causing the collar and plunger to rotate in unison while allowing reciprocal movement of the plunger.

Steerable wheel suspension assembly

A fuel-feed system for engines, gas turbines, burners and the like, including a fuel pressure source communicated with a fuel tank and a porous piezoelectric ceramic filtering element, such as barium titanate, connected to a generator of electric oscillations and placed into a housing which inlet and outlet are separated by said element. The latter can be shaped as a hollow needle of a fuel-injector valve, said outlet equipped with a valve seat interacting with a free end of said element.

Fuel-feed system

A machine lubrication system including a lubricant pressure line communicated with a lubricant reservoir by means of a nozzle provided with a hydrodynamic means to break-down solid contaminants of lubricant to a non-interferring size.

Machine lubrication system

A hydraulic system including a working-liquid pressure line and drain line communicated accordingly with an inlet and outlet of a housing into which a porous piezoelectric ceramic filtering element, such as barium titanate, is placed, connected to a generator of electric oscillations and separates said inlet and outlet.

Hydraulic system

A machine lubrication system including an oil-lubricant pressure source communicated with a reservoir means and a means for maintaining the working properties of the lubricant, wherein the latter means constitutes a porous piezoelectric ceramic filtering element, such as barium titanate, connected to a generator of electric oscillations and placed into a housing which inlet and outlet are separated by said element.
