Abstract: A new and improved kingpin housing assembly operatively coupling the wheel mounting assembly, the front axle and the steering assembly with the help of kingpin. The kingpin housing assembly is provided with upper and lower arm supports. The lower arm support provides a new and improved locking mechanism to keep the kingpin in place. For the kingpin housing assembly to function efficiently, the kingpin used to couple the wheel mounting assembly to the front axle must always be securely held in place to prevent wear and tear during road shocks and rapid steering maneuvers. The kingpin is held in place with the help of a locking cap received into the lower arm support and locked in place with the help of a nut and bolt combination. The lower arm support is provided with castellations along the bottom circumference. A horizontal bore is provided in the locking cap across its diameter.

Abstract: A sorter is described that optically differentiates acceptable objects from unacceptable objects. The sorter illuminates the objects as they move in a stream through a viewing zone with both visible and infrared light. The detecting system and circuit provides electric signals proportional to the light transmitted or reflected by the objects to a microcomputer system which in turn activates a rejection mechanism if unacceptable objects are viewed. The microcomputer system determines what objects are unacceptable by comparing signals for objects being viewed with stored signals for acceptable objects.

Abstract: This invention is a folding warning marker device with multiple panels formed from a sheet of cardboard or other folding material. For exemplary purposes, the invention herein is shown as a four sided truncated cone having various warning indicia on the surface. It is characterized by ease of stacking and storage and toward that end can be stored in a flat layout condition. Disposed at the top of the cone is a vertical slit on opposing sides allowing for the insertion of a ribbon fence from one safety cone to the next thereby cordoning off an area of danger. The top of the truncated cone is characterized by a flap that folds over the slits in order to thus fasten the ribbon passing through to the safety cone. The bottom of the safety cone is characterized by folding flaps thus forming a base of a cone and thus securely holding the structure in place.

Abstract: Disclosed is a cartridge-type flow control valve principally for use in public drinking fountains. The cartridge-type valve includes a substantially cylindrical housing open at one end. Mounted within the housing is a fluid transfer member which includes an integrally formed fluid transfer chamber, inlet nozzle and outlet nozzle. A valve stem slidably extends into the fluid transfer chamber and is sealed by means of O-rings. The valve stem includes a substantially cylindrical eccentric protrusion which can be used to regulate the amount of flow through the cartridge valve. The eccentric protrusion is adjacent to the inlet bore to the fluid transfer chamber and thus, by rotating the valve stem, the gap between the eccentric protrusion and the inner wall of the fluid transfer chamber at the inlet bore can be varied. Varying this gap allows some amount of flow control.The valve stem has attached thereto a valve stem cap.

Abstract: A personnel activity sensor and alarm system is provided which incorporates one or more remote personnel safety units each incorporating a multi-axis motion detector and reset timing and logic circuit coupled with a radio transmitter or transceiver. Under the command of the logic circuit, the radio automatically transmits an alarm signal and causes the circuitry to generate a local audio signal in the event of personnel inactivity for a predetermined period of time. This enables personnel assistance to be initiated without delay. A base station is also provided which incorporates a radio transceiver to which is coupled control logic circuitry for commanding transmission of radio integration and control signals to the radio receiver of the remote personnel units for acknowledgment of alert signal reception and for cancellation of the radio alarm signal to clear the radio channel for other activities.

Abstract: Disclosed is a process for removing polychlorinated biphenyls from electrical apparatus, particularly transformers, to achieve concentration levels of 50 ppm or less as required by the EPA. A dielectric fluid having a relatively low boiling point as compared to polychlorinated biphenyls and other contaminants and in which PCB's are soluble is selected. There is an external cooling loop through which the dielectric fluid is circulated maintaining the temperature and pressure of the transformer within its design limits. There is an external distillation loop where the liquid removed from the transformer is heated to boiling point of the selected dielectric fluid thereby vaporizing the dielectric fluid and leaving the polychlorinated biphenyls in liquid phase in the distillation vessel. The dielectric fluid vapor is then condensed and returned to solubilize remaining PCB's in the transformer.

Each recess has a radial shoulder tapered with respect to a transverse plane disposed between the flanges such that the axial distance between the radial plane and the shoulder at a maximum diameter is greater than the axial distance from the plane to the shoulder at a minimum diameter. Each recess also has an inside frustoconical surface tapered with respect to the longitudinal axis with a minimum inside diameter adjacent the shoulder, and a maximum inside diameter adjacent a face of the flange. A bifrustoconical annular seal ring has outside and end surfaces complementarily tapered to engage the shoulder and the inside surface of the recesses.

Abstract: A device for assisting invalids into and from a seated position, e.g., over a toilet. The device has a frame and a seat hingedly attached at the front thereof to a support member which is vertically slidable on the frame. A stop is associated with the hinge to prevent the seat from pivoting below the horizontal attitude. An extendable arm is connected at one end to the frame and, at the other end thereof, to the seat between the hinge and the center of gravity. Control means selectively activates extension of the arm to initially vertically elevate the seat in the horizontal attitude, and then to pivot the seat upwardly to assist an individual seated thereon into a standing position; or activates retraction of the arm to initially pivot the seat into a horizontal attitude, and then to vertically lower the seat in a horizontal attitude to assist an individual into a seated position.

Abstract: Disclosed is a self-contained, portable apparatus for cleaning chemical and/or radioactively contaminated articles. A cleaning chamber is provided where contaminated articles are placed. Solvent from a solvent reservoir is sprayed onto the contaminated articles to dissolve the chemical contaminants and to dislodge the radioactive particulates. The solvent and contaminants drain through a short vertical duct connecting the cleaning chamber to the solvent reservoir. There is a cooling means present in the short vertical duct which serves to condense the solvent vaporized during the cleaning operation. A filter means is provided to filter particulate contaminants from the solvent before the solvent is delivered from the solvent reservoir to the cleaning chamber.
