A liquid vaporizer or boiler for vaporizing organic working fluids without substantial decomposition thereof. A combustor of the vaporizer includes a plurality of strip burners for introducing a mixture of primary air-fuel into a baffled combustion chamber; and a strip nozzle adjacent each strip burner for introducing and turbulating secondary air with the primary air-fuel to effect combustion in the combustion chamber that is substantially free of hot-spots. A zig-zag tube bundle down stream fr...

A liquid thrust bearing has provision for minimizing leakage, automatically eturning leakage to a reservoir, and automatically restoring any lost fluid to the pressure/thrust area each time the thrust is removed.

A liquid reservoir for use with a tandem master cylinder of a vehicle hydraulic system includes a dividing wall which serves to define a pair of chembers, the diving wall also defines in the chambers respectively guideways which guide the vertical movement of float assemblies. Each float assembly includes a magnet operable to close a pair of contacts in a switch housed in the dividing wall when the liquid level in the respective chamber falls below a predetermined level.

A liquid spring constructed using a sliding shock or piston head member on a piston rod and incorporating spring means under the piston head. This liquid spring includes an outer cylinder or housing closed at the top with a threaded in closure head containing a filler plug. Beneath this member is a first seal to provide a leak proof container at that end. The other end of the cylinder or housing is constructed so as to provide an integral mass that formsa portion of a second closure means. This ...

A spin- or thread-on type oil filter whose filter housing which mounts within its interior space the filter element or cartridge comprises a cylindrical, thin sheet-metal shell or can body closed at one end by an integral dome-shaped end wall and at its other end by a separately fashioned closure plate assembly made up of a heavy-gauge metal base plate whose outer rim portion is planar and has diameter substantially equal to the inner diameter of the shell, and an annular sheet metal seaming cov...

A liquid container comprising a cup, the contents of which have a more or less low viscous consistency, which is closed by a lid. Radially inwardly of the pouring edge of the cup the lid has a recess which comprises a bottom and an annular side wall, said side wall being spaced from the inside surface of the cup so as to present around a portion of its circumference a slot-like interspace between the inside surface of the cup and the annular side wall. The volume of liquid contained in the cup i...

A discharge arrangement for a liquid reservoir such as a toilet cistern, in which the cistern is of an airtight type. The arrangement of the present invention is that the cistern is provided with a liquid outlet port with a compressible seat surrounding the port. The seat includes a liquid passageway with a liquid inlet hole, a vent hole and a liquid outlet hole. Sealing means, such as floatable ball, is adapted to mate in sealing arrangement with the seat. There is also provided suitable means ...

A centrifugal separator comprises a pair of centrifugal pumps of the airfoil type. A mixture of liquids of different specific gravities is fed centrally to one pump and the heavier liquid is withdrawn from the periphery of that pump. The other pump withdraws the lighter liquid from the center of the first pump and discharges the lighter liquid peripherally.

A liquid laser, particularly a dyestuff laser, is provided with a liquid guiding chamber through which circulates a cooled laser liquid and which is provided with a U-shaped laser active zone formed by a light transmitting longitudinal cap into which extends a tongue forming in said cap a U-shaped zone of uniform cross section. This U-shaped laser active zone is disposed in a focal line of an elliptically shaped pump light reflector while a source of pump light is disposed in the other focal lin...

A liquid sprayer comprises a tubular body with a solid end wall. A transverse slot extends diametrically across the exterior face of the end wall and a hypodermic tube extends through a drilling intersecting the slot. The ends of the tube are seated externally of the body and it is formed adjacent its ends with openings inside the body. Within the slot a discharge slot is formed in the tube. The body is contained in an air casing with air discharge ports to create a flat fan-shaped air flow patt...
