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 height adjustable table includes a frame that has a pair of spaced apart, generally vertical frame sections, each supported upon a foot, a transverse, generally horizontal section that connects at its end portions to the vertical sections and a pair of lifts that are supported by the vertical frame sections to. elevate between extended, higher elevational and retracted, lower elevational positions. The lifts support a table top with a work surface. The frame is in the form of a universal base that accepts a number of different mechanism including, for example, a counterbalance mechanism, a motor drive mechanism, and a manually operable mechanism. These mechanisms can be selected by a user, depending upon the type of table that is to be manufactured. This enables the user to pick and choose a mechanism so that the manufacturer can use the same universal base in the construction of three different table designs. A plurality of panels are provided that cover the frame.

A counterbalance spring can be used to counterbalance loads of different amounts such as when different objects are supported by the table work surface. A load indicator indicates to a user whether or not the counterbalance mechanism is in balance with a load placed on the work surface.

Abstract: A dual float snorkel vent for use in sealing a well conduit vent cap from flood waters that could contaminate well water therebelow. A lower float causes an upper float to seal a check valve as water rises and prior to water reaching the level of the upper float and the snorkel vent is positioned at an appreciable vertical distance below an inlet to the vent cap to ensure that no water enters the vent conduit.

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).

Abstract: A manipulator (10) for adjusting the curvature of a bendable refocusing mirror (72) which is positioned inside of a high-vacuum optical apparatus is disclosed which is particularly adapted so that manipulation of the curvature of the mirror (72) can be accomplished on the outside of the apparatus through adjustment of a manually operable micrometer (46). A single feedthrough shaft (54) extends into the vacuum of the apparatus and is operable by the micrometer (46) so as to raise and lower one end each of a pair of drawbridge members (62, 64), each of which is attached to one end of the mirror (72) so that equal bending moments are applied at opposite ends of the mirror (72) so as to adjust the curvature thereof in a preselectable and uniform fashion.

Abstract: An extended range grazing incidence monochromator is disclosed which utilizes Rowland circle geometry to select a frequency of radiation from a broad spectrum of radiation, with the entrance slit and the gratings of the monochromator being positionable by remote electrical control, such as that provided by a digital computer, while the exit slit of the apparatus remains fixed. The monochromator has an extended range because it includes two different gratings, each of which has an optical characteristic adapted for use in a Rowland circle of a different size, and the apparatus is capable of switching between two gratings without breaking the ultra-high vacuum contained in the interior of the monochromator. The positioning of the entrance slit and the appropriate grating is accomplished both rotationally and linearly through the use of stepping motors which can be precisely remotely controlled for maximum accuracy and control.

Abstract: A improved high pressure seal for sealing between a pair of vacuum system elements (10, 12) is disclosed which includes a channel (42) to allow fluid to be vented from the space between a sealing member (30) and a seal on the low pressure side of one of the elements (10, 12) to prevent the trapping of gasses inside of the seal which can contribute to outgassing at a later time. The venting channel (42) is formed either in the deformable sealing member (30) itself, or in one of the two vacuum system elements (10, 12) in its face adjoining the sealing member (30).
