Abstract: A packing arrangement for a fluid end of a reciprocating pump is received within a packing box and is arranged to form a seal with a plunger. The packing arrangement includes a plurality of separate annular rings arranged in an abutting relationship with one another within the packing box, and a header ring disposed within the plurality of separate annular rings, the header ring including an inner surface that is non-cylindrical and that is arranged to abut the plunger, a high pressure side that is arranged in a female chevron shape, and a low pressure side opposite the high pressure side. A packing nut is engaged with the fluid end and operable to compress the header ring and the plurality of separate annular rings within the packing box.

Abstract: A reciprocating pump includes a casing defining a pumping chamber, a plunger configured to reciprocate in an axial direction within the pumping chamber along a plunger axis, and an annular header ring positioned between the plunger and the casing. The annular header ring is formed solely of a fabric-reinforced rubber.

Abstract: A weeding robot includes a chassis, a motorized cutting subsystem, a drive subsystem for maneuvering the chassis, a weed sensor subsystem on the chassis, and an acceleration sensing subsystem mounted to the chassis. The drive subsystem is controlled to maneuver the chassis about a garden by modulating the velocity of the chassis. Upon detection of a weed, the motorized cutting subsystem is energized to cut the weed. The acceleration of the chassis is determined based on an output of the acceleration sensing subsystem. The drive subsystem is controlled according to one or more preprogrammed behaviors if the determined acceleration of the chassis falls below a predetermined level.

Abstract: A glide assembly is adapted to be mounted about an existing foot attached to the free end of a leg of a piece of furniture that is adapted to be supported upon a surface. The glide assembly includes a body defining an exterior surface and a bore extending partially through the body to define a hollow interior, an interior surface, a top, open end of the body, and a bottom, closed end of the body disposed opposite the open end. A cap is designed to be replaceably attached to the closed end of the body and adapted to engage the surface upon which the leg is supported.

An insert assembly is mountable about the foot and adapted to be received through the open end and fixedly secured within the hollow interior of the body so as to mount the body about the foot. A cap is designed to be replaceably attached to the closed end of the body and adapted to engage the surface upon which the leg is supported.

Abstract: A foot assembly is adapted to be removably attached to the elbow of a sled-type leg of a piece of furniture that is adapted to be supported upon a surface. The furniture-foot assembly includes a body defining a hollow interior adapted to removably receive the elbow of the leg and a bottom exterior portion. A glide is adapted to be removably mounted to the bottom exterior portion of the body and supported upon the surface for gliding movement of the furniture-foot assembly relative to the surface.

Abstract: Topical cosmetic and pharmaceutical oil-in-water emulsions wherein an emulsifier blend, comprising a mixture of at least two sucrose esters in combination with at least one solid fatty alcohol, forms a multi-lamellar liquid crystalline network that effectively moisturizes and protects the skin, and provides a useful vehicle for delivery of active ingredients. Sucrose esters are used in emulsions of the present invention at very low concentrations (from about 0.2 % to about 1.2 % by combined weight of sucrose esters relative to the total weight of the emulsion).

Abstract: The present invention relates to transparent or clear emulsions for cosmetic or pharmaceutical use that are suitable for application to the human lips and to the facial area around the lips. The transparent emulsions of the present invention comprise an oil phase, containing at least one lipophilic solvent; an aqueous phase; and an emulsifying system containing at least one non-ethoxylated fatty acid ester emulsifier having a hydrophilic-lipophilic balance (“HLB”) from about 11 to about 16. Preferred non-ethoxylated fatty acid ester emulsifiers are sucrose esters, in particular sucrose palmitate and sucrose laurate.

Abstract: A replaceable stool assembly is adapted to be removably mounted to the free end of a tubing of a piece of furniture. The assembly includes a base portion adapted to be removably mounted to the free end of the tubing and defining a plurality of reinforcing ribs disposed on the base portion for adding structural integrity to the base portion. The stool assembly further includes a seat portion adapted to operatively support a user of the assembly and be nestingly received by and removably supported on the base portion.

Abstract: A glide assembly is adapted to be securely fastened to the free end of a leg of a piece of furniture. The assembly includes a body defining a bore extending partially through the body to define an interior surface, an open end, and a closed end of the body. The free end of the leg is adapted to be inserted within the bore. A post extends from the closed end at least partially toward the open end of the body and is adapted to be received through an opening of and within the free end of the leg with the free end of the leg being adapted to be matingly received between the post and body. A clip is supported upon the post and adapted to be in abutting contact with an interior surface of the free end of the leg to securely fasten the body about the free end of the leg.
