Abstract: An elastic hose for conducting a liquid from a source such as a water fixture or a storage container to a delivery site is disclosed. The hose includes an upper funnel-shaped portion and at least one contiguous lower cylindrically-shaped portion. The upper portion may be stretched over a water fixture, a liquid container, or the like to form a gripping leak-proof seal. The hose has a stretchability of about 400%-1,000%. The lower portion is led to a delivery site. The hose is able to conduct liquid from a source to the delivery site without spills or mess. Moreover, in the case of a leaky faucet, the hose eliminates splashing and substantially decreases the noise generated by the leaking water.

Abstract: An apparatus for securing a generally flexible cable to one end of a generally flexible tubular pipe liner which has been impregnated with a thermosetting resin comprises a reinforcing member for reinforcing the liner end to distribute any tension exerted by the liner on the cable. A portion of the liner proximate the one end of the liner is flattened, with the interior liner surfaces interengaging to close the one end and to establish two generally flat liner end portion sides, the flattened liner end portion including a plurality of openings extending therethrough from side to side, the reinforcing member being secured to both sides of the flattened liner end portion. The reinforcing member includes a plurality of openings extending therethrough, the reinforcing member openings being in registry with the liner end portion openings. Fasteners extend through the registered openings in the liner end portion and in the reinforcing members for securing the reinforcing member to the liner end portion.

Abstract: A fluid connector is provided which is especially adapted for use with low-pressure fluids. The fluid connector comprises a bored mobile joint possessing an internal chamber communicating with a tubular conduit and upper and lower coaxial, opposed bore-holes whose common axis is substantially perpendicular to said tubular conduit. A screw brace is inserted into said bore-holes. The leg portion of the screw brace possesses an internal conduit which is co-axial with the common axis of the bore-holes and which communicates with the internal chamber, said leg portion further possessing upper and lower annular grooves and a threaded portion starting below the lower annular groove. A metallic retaining ring is positioned below the upper bore-hole and is disposed within the upper annular groove.

Abstract: A compensating reservoir for a hydraulic brake system includes an upper part provided with a fill socket and a lower part which is provided with an outlet. The parts are connected with each other in a liquid-tight manner along a separating or joint line. The fluid chamber, which communicates with a filling and supply opening of a brake master cylinder through the outlet, is subdivided into two chambers by a partition wall and contains an auxiliary chamber with a level indicating float. The auxiliary chamber communicates with the fluid chamber. In order to determine the actual fluid level by a float not arranged in the fluid level's areal center of gravity resulting from the shape of the reservoir, the two chambers hydraulically communicate with each other permanently, with the first chamber containing both the auxiliary chamber and the outlet and with the second chamber being closed in a liquid-tight manner.

Abstract: Double tubing comprises two flexible plastic protective tubes (1, 2), integrally joined with one another via a web (5), which are embodied as corrugated tubes. For installing the double tubing without damage and to prevent deformation of the protective tubes, and in this manner to make them particularly suitable for plumbing applications, fastening holes (11) for fastening screws (17) are embodied in the web (5). Each fastening hole (11) is embodied between two corrugation crests (3) disposed opposite one another in pairs, and in the area of the respective fastening hole (11) the crests (3) are deformed into secant-like defining walls (12) of the respective fastening hole (11).

Abstract: A device is placed in a horizontal duct, whose outlet issues into a gaseous medium, in order to retain liquid normally circulating in said duct when the flow drops below a given threshold. This device has tubes having at least one low point and at least one high point located downstream of the low point. Therefore the tubes can be helically wound around a core. At their upstream end, the tubes are fixed to a tight plate. Holes made in the tubes at the location of the high points prevent any siphon effect. Thus, liquid plugs form in the tubes when the flow is low or zero.

Abstract: A substantially homogeneous heavy wall drill pipe and its method of manufacture are disclosed. A cylindrical ingot is placed in a multi-hammer forging press to form the ingot into a drill pipe bar having a central protector portion and upper and lower connector sections each of larger diameter than cylindrical body sections of the drill pipe. Thereafter, the bar is straightened and upper and lower end connectors are machined. Threaded end portions are machined on the connectors and a bore is drilled through the drill pipe bar.

Abstract: A method for compacting and/or filling of pulverulent materials into rigid or flexible containers in the course of which the pulverulent material is filled into the container with the help of a pipe in relative motion to the container, and separated from the gas, for example air, transported along with the help of a separation device which surrounds the pipe and is fitted to the container cross section. The pulverulent material is retained in the container with the help of the separation device, while the gas escapes through the gas permeable separation device.

Abstract: An automatic overfill prevention system for gravity filling of an underground liquid storage tank from a tank truck fill line provides a venturi in the fill line creating a partial vacuum which is vented from the liquid storage tank through a vent line until the liquid in the storage tank rises to a predetermined level to submerge one end of the vent line and trigger a latching means to close the fill line. The assembly also includes a containment manhole to hold any inadvertent spillage occurring during the filling process.

Abstract: A method for in situ rehabilitation of deteriorated underground piping featuring ease of installation.

Abstract: An expandable pipe plug can be constructed so as to use a peripherial elastomeric sleeve having an exterior surface which is adapted to seal against the interior of a pipe and a tapered internal surface which fits against a correspondingly shaped, tapered surface of a rigid expander. The tapered surfaces of the sleeve and the expander are provided with coaction threads so that as the expander is turned the sleeve will be expanded outwardly. The expander includes a stud for use with a tool such as a wrench in turning it relative to the sleeve, this stud including an internal threaded passage which is initially closed off by a knock-off disk. The passage can be used in connecting a pipe, a gauge, a valve of the like to the end of a pipe sealed off with the pipe plug.

Abstract: A backpack is provided which has at least one sleeve secured to a panel of the backpack, which sleeve is sized and structured to closely receive and hold an insulated container that is readily removable from this sleeve, when desired.

Walls of the insulated container are constructed in order to provide thermal insulative properties thereacross.

Abstract: A slat assembly for vehicle luggage racks is disclosed with a snap-in end cap. The end cap has a shank portion which is telescoped inside the end of the channel-shaped slat and a head portion is disposed exteriorly of the slat. A detent element in the form of a tang in the base of the slat coacts with a detent element in the form of a ramp surface on the bottom of the shank of the end cap to interlock the end cap and slat. A stud is molded into the end cap for mounting the slat assembly on a vehicle body panel.
