Abstract: A livestock free stall is provided, having a pair of vertically oriented posts held in fixed spaced relationship. Each of the posts has attached thereto in parallel spaced relationship upper and lower receiver tubes or posts with the receiver tubes or posts of each stanchion oriented in parallel spaced relationship to the corresponding upper and lower receiver tubes or posts of the other stanchions. A pair of rail loops, each having upper and lower ends, are then configured and sized for insertion into the upper and lower receiver tubes, or for receiving the upper and lower receiver posts, is then attached and fastened to the stanchion. A top rail interconnects the posts to form the completed free stall assembly.

Abstract: A motorized dump-type vehicle is provided having a chassis frame, an engine mounted on said frame, a dump container pivotally mounted on the front of said frame and a hydraulic system enabling said container to be raised and lowered by a hydraulic cylinder and said vehicle to be driven in either forward or reverse directions using its front wheels. Additionally, as needed, the vehicle can be switched into all-wheel-drive by hydraulically driving the vehicle's rear wheel(s) which are by default undriven.

Abstract: A novel skate platform wheel truck and wheel design is disclosed which incorporates five wheels per truck, with a larger center wheel with a convex or flat running surface, and two smaller side wheels with a beveled surface. This configuration permits more fluid and responsive turning of the skateboard.

Abstract: Right rectangular parallelepiped construction modules including a system of latitudinal tangs and grooves and inner and outer shoulders which cooperate to interlock stacked or staggered construction modules. The construction modules can also include reliefs in their tops, sides and bottoms for receiving rebar supports, electrical lines, plumbing lines, or other means.

Abstract: This invention demonstrates the methods that use semiconductor laser amplifier (SLA) as a wavelength discriminator, as well as several apparatus designed using these methods. The functions of the invented apparatus include wavelength measurement, wavelength tracking, wavelength comparison, and wavelength stabilization and control of lasers. The key concept for which these methods and apparatus work is the variation of the transparent current of a SLA with the wavelength of an incident light. The transparent current of a SLA can be easily detected from the induced voltage across the diode junction when the incident light is intensity-modulated. The incident wavelength can be accurately determined by measuring the transparent current. These methods and apparatus are expected to be very useful in wavelength display for photonic instruments, wavelength control and wavelength registration for photonic networks, and wavelength stabilization for laser diodes.

Abstract: A modular storage system which includes a support rail mounted on wall or ceiling, in horizontal or vertical orientation, with slidably adjustable cantilevered hooks, from which are hung storage boxes fitted with a frame on the open side, and a transparent hinged door. A hanger and straps are utilized to attach the rigid frame to a storage box. Reinforcing support brackets can also be attached to a storage box on its underside or top, and suspended from cantilevered hooks of the modular storage system.

Abstract: A method of producing apparatus for use in fiber processing, and in particular blades for pre-carding flats in a cotton card. The method comprises the steps of providing a body (32) defining a multiplicity of bores (34) extending between rear and front faces thereof, providing a multiplicity of pointed pins (44) of corresponding diameter to the bores, locating the pins (44) in the bores (34) from the rear of the body such that the points extend from the front of the body, and fixing the pins in the body.

Abstract: A terrain following hitch which mounts on a tractor draw bar by a pin, and which allows an implement being towed to move in three planes, independent of the tractor. The hitch includes three hinges, and a draw bar attachment tube which fits over the draw bar of a tractor, and transmits force to the walls of the draw bar, instead of into the pin and pin holes. The hitch reduces wear on implements and hitch connections.

Abstract: The invention is a bi-directional cleanout for pipelines such as sewer pipelines and a bi-directional cleanout with a built in backflow preventer. The backflow preventer is a check valve which allows fluid to flow in one direction, but not in the other direction. The bi-directional cleanout is a device which has a single access point at ground level, is located outside a house typically, and which directs a cleanout tool down one of two tool guide tubes. The guide tubes direct the cleanout tool into one of two tool guides which deflect the cleanout tool and cause it to enter the pipeline to be cleaned in a direction towards one or the other of the ends. The check valve is insertable into the pipe level unit in which the tool guides are located. While the pipeline is being cleaned out with the cleanout tool, the check valve can be removed and reinserted after the cleanout procedure is completed.

Abstract: A socket test probe and a method of making the probe which results in a probe head which has flat plates which serve as electrodes encased in resin. The electrodes are conductive plates with one or more edges of the conductive plates exposed for connection to the electrodes of a socket. The entire probe head starts as a solid block of conductive material which is drilled, machined, filled with resin and machined again to form a socket testing probe utilizing the edges of conductive plates as electrodes.

Abstract: There exists many different devices for connecting articles of clothing together. The present invention is such a device for attaching articles of clothing together. The present invention utilizes paired fasteners on each of the two articles of clothing to be attached together. This allows the two articles to either be attached together or turned inside out and folded upon themselves and attached to themselves. In this folded-down state, the fasteners are hidden from view.

Abstract: A tool for opening a sealed telephone cable splice box. The tool has a fulcrum adapted to bear against various points on the ends of the splice box. The tool also has a lever adapted to cooperate with the fulcrum and a sliding member that slides longitudinally along the lever and is adapted to bear against the box top. The top of the box is separated from the bottom and ends of the splice box by transferring force between sliding member and the fulcrum through the lever.

Abstract: A secondary containment tub, comprising a lower leak proof compartment having an upper rim and a base and a cover hinged to the upper rim by hinges. A metal collar extends around the upper rim. A flange on the base is provided for securing the lower leak proof compartment to a support. A tank is disposed within the secondary containment tub, with the tank being supported above the base of the lower leak proof compartment, preferably on a metal frame, at a level such that the tank cannot float in fluid spilled from the tank into the lower leak proof compartment.

Abstract: A supplemental fuel regulator for diesel engines, and a system for adding supplemental fuel to diesel engines is provided. The fuel regulator has two chambers, one which receives fuel from the fuel tank through a fuel inlet valve, which also reduces the pressure of the fuel. The fuel at much reduced pressure is passed to a second chamber through a fuel control valve. Fuel is drawn from the second chamber into an outlet duct, directly into the airflow duct of the diesel engine. A vacuum line from the engine pulls fuel from the second chamber. As engine demand increases, the engine vacuum increases, and additional fuel is supplied by the regulator. A solenoid switch provides control over the system, which can be activated by a user when the supplemental fuel system is deemed desirable. The solenoid switch can be configured to shut off the supplemental fuel system whenever the diesel engine is shut off.
