Plastics material mesh which has spaced, longitudinal, oriented strands is used to form a retainer construction for retaining fill in a geotechnical structure. Triangular compartments are formed by having a number of parallel elongate portions of the mesh and interconnecting them by zig-zag portions, each zig-zag portion thus being mainly contained between the two respective elongate portions, and being joined to the adjacent zig-zag portion at respective corners of the compartments. The connect...

A fast-fill master cylinder with integral proportioning includes a housing with a stepped bore defining a large diameter and a small diameter. A piston is disposed with the large diameter and the small diameter to form a fast-fill chamber in the large diameter and a pressure chamber in the small diameter. A passage extends between the fast-fill chamber and an outlet port to bypass the pressure chamber.

Apparatus for removing a fill yarn from a web of warp tows advances the web lengthwise across a tabletop having opposite pairs of bars at the leading edge thereof for separating the outermost tow at each of the opposite edges of the web from the remaining tows within the web. Rotatable cutting wheels which are resiliently urged against the top of a rotating shaft at the underside of the web sever the fill yarn between the outermost tows and the remaining tows of the web to form separate fill yar...

A differential fill valve assembly for application in float collars or shoes in well casing. The valve assembly comprises a back pressure flapper valve disposed within a substantially tubular upper housing, and a lower housing containing an activating sleeve slidably disposed therein above a double flapper valve assembly. The activating sleeve initially extends into the upper housing to a sufficient extent to maintain the flapper valve in an open position; the activating sleeve is maintained in ...

A master cylinder includes a housing defining a reservoir and a bore for movably receiving a pair of pistons. A primary piston cooperates with a secondary piston to define a primary chamber therebetween and cooperates with the housing to substantially define an auxiliary chamber. The primary chamber and auxiliary chamber are disposed within a substantially uniform diameter section of the housing bore. The primary piston is movable within the bore to communicate fluid pressure from the auxiliary ...

A direct indicating automatic stop fill valve is mounted to the inlet to an LPG tank whereby inlet ports to the tank volume are covered by a slidably mounted cylinder which is raised through contact with a float/cam arrangement until the tank level reaches a predetermined level. The cylinder is then driven into a sealing position to stop the flow into the tank by a differential pressure force resulting from the inlet pressure being higher than tank fluid pressure. The cylinder also supports a dr...

A food product fill pump apparatus and method are disclosed which greatly facilitate accurate and efficient sequential filling of containers with food product which is flowable in nature. The fill pump is adapted for use with associated packaging machinery for placing predetermined quantities of food product in a plurality of containers which are sequentially presented for filling. The fill pump includes a reciprocating positive displacement piston pump and a rotary valve which are cyclically op...

A fill pipe lock assembly for protecting the fill pipe cap of an underground flammable liquid storage tank is disclosed. The lock assembly includes a floating baseplate inserted over the top of the fill pipe and below the adaptor ring and a removable cover. The baseplate is in loose engagement about the fill pipe in a manner which permits the baseplate to be rotated freely about the fill pipe. The baseplate and cover include a pair of cooperating, diametrically opposed, hasps and openings to rem...

A toilet fill valve and methods are provided. In one embodiment, the toilet fill valve includes a water inlet and a first water outlet configured to supply water to a toilet tank. The toilet fill valve further includes a bowl fill valve having a bowl fill valve inlet and a bowl valve outlet, the bowl fill valve inlet being operatively coupled to the water inlet. The bowl fill valve is integrated with a body of the toilet fill valve. The bowl fill valve is configured to supply an adjustable flow ...

Gravity fill line vent fitting includes a body member having a water fill opening and vent opening adapted to be connected to the elevated ends of a water fill line and surrounding air vent line, respectively, of a potable water storage tank. An inner tubular extension and surrounding hose fitting may be connected to the inner/bottom side of the body member for use in attaching the water fill line and air vent line, respectively, to the body member. An outer tubular extension and surrounding ser...
