Abstract: A yard hydrant has an elongated wet pipe with a plunger that seals against the inside of a well casing. Lifting a pivoting handle at the top of the wet pipe lowers the wet pipe which opens a normally closed supply valve. Pressurized water can then flow up the wet pipe and out of a nozzle head mounted to the upper end of the wet pipe. Lowering the handle pulls the wet pipe upward, thereby clearing it from the supply valve which is spring biased to shut off the water supply. The handle has a cam that positively actuates a normally closed anti-siphon valve so that water left in the wet pipe can fall under gravity to a collection chamber within the well casing beneath the piston. Lifting the handle again lowers the wet pipe and forces the water in the collection chamber back up the wet pipe. At the same time, the anti-siphon valve will close and the wet pipe re-opens the supply valve.

Abstract: An adjustable height table has a frame with spaced apart side portions spanned by a horizontal tray with a knee area below the tray. Each side has a foot that engages the floor or like support surface. Each side includes a lower non-elevating base part and an upper elevating “lift” part. The non-elevating and elevating portions each have an outer wall, a hollow interior and vertical slots that face in opposite respective directions for a given side (including a non-elevating portion and an elevating lift portion). A gear mechanism interfaces the upper “lift” and lower “base” parts. When the table is in an extremely elevated position, roller supports minimize lateral translation. The roller supports fit shaped rails on the elevating parts. The frame can receive any of three selected mechanisms. Each mechanism features a horizontal shaft contained within the tray.

Abstract: A well construction includes a spool with a skirt that seats against a collar in a vertical well casing, the collar and skirt cooperating to limit the downwardly longitudinal movement of the spool within the casing. Both the skirt and collar form keyed surfaces each defined by a specific pattern of indentations and protrusions. The skirt and collar keyed surfaces are at least partially complementary so that, when the spool is in an operational position, the two surfaces intermesh and either eliminate or substantially reduce spool rotation within the well casing.

Abstract: A well construction includes a spool (12) that is insertable into a vertical well casing (14). The spool (12) has a skirt (28) that seats against a collar (26) of the well casing (14). The skirt (28) and collar (26) are of a pre-selected angle and material so as to create a sliding and non-sticking engagement between the surfaces of the skirt (28) and the collar (26). A support web (50) extends substantially perpendicular to the surface of the skirt (28) at the location of the skirt (28). A pipe is suspended from a sleeve portion (44) of the spool and a ring portion (53) is formed at the junction of the support web (50) and the sleeve (44). The sliding and non-sticking engagement between the skirt (28) and the collar (28), coupled with the geometry of the spool (12), creates a load distribution in the support web (50) of substantially compressive forces between the surfaces of the skirt (28) and the collar (28), thus minimizing the incidence of breakage in the spool (12).
