Abstract: A molded resin folding chair having a pair of uprights generally parallel to and spaced apart from each other being connected by at least one cross piece forming a backrest. At least a portion of each upright has a generally C-shaped channel. A seat has a rear portion and opposite sides thereof provided with a tab that is slidably engaged in the C-shaped channel of a respective upright. A pair of struts each have an upper end rotatably attached to the seat and a medial region rotatably attached to respective uprights. The folding chair is folded by sliding the rear of the seat upwards, causing the front portion to move downwards, via the tabs sliding in the C-shaped channels. The struts rotate about the rotatable attachments to the seat and uprights, such that the uprights, struts and the seat fold as flat as possible.

Abstract: A temporary ball valve support structure is utilized to apply pressure to the ball in a ball valve so that a seal is maintained between the ball and the upstream seal member in the ball valve to prevent fluid from leaking from the valve while the valve is being serviced. The temporary ball valve support allows a downstream seal member and the ball valve retainer housing assembly to be removed. This allows the outer seal and retainer to be replaced and/or serviced without allowing fluid to escape from the tank or pipe. First and second ball support members are alternately used to force the ball member against the upstream seal member.

Abstract: An apparatus for decontaminating air within an enclosed workspace located downstream and in fluid communication with the apparatus. The apparatus includes a housing containing an array of ultraviolet lamps mounted within an enclosure in the housing. The enclosure has an intake aperture and an exhaust aperture. The housing and the array form an airflow processor such that uncontaminated air entering the intake aperture passes through the array before exiting the exhaust aperture. An airflow motivator, which may be a fan, urges the airflow through the housing and the array from the intake aperture and out through the exhaust aperture. A downstream conduit, which may be a flexible hose, is in fluid communication between the exhaust aperture and the workplace directs the airflow into the workplace alter being processed in the airflow processor. The intake aperture is positionable relative to the workspace so that the airflow entering the intake aperture is uncontaminated air.

Abstract: Determination of the rate penetration (ROP) of drilling has usually been based upon surface measurements and may not be an accurate representation of the actual ROP. This can cause problems in Logging While Drilling (LWD). Because of the lack of a high-speed surface to-downhole communication while drilling, a conventional method of measuring ROP at the surface does not provide a solution to this problem. However, the instantaneous ROP can be derived downhole with a certain degree of accuracy by utilizing an accelerometer placed in (or near) the tool to measure acceleration in the axial direction.  When three-component accelerometers are used, the method may be used to determine the true vertical depth of the borehole.

Abstract: An electroporation reactor for continuously processing products such as agricultural products and animal products in the form of pieces. A drum (7) with catch elements (5) on the outer covering surface thereof rotates in a process fluid, mainly water, which is retained in a chamber, and transports the items to be processed, said items being fed through an inlet. The process or harvest products are then degassed by immersion until they proceed as far as the actual processing zone where they are exposed to high intensity electric fields during a short period of time, so that the potential difference which is necessary for the poration on the cell walls of the process items can act on the longer cell axis. When the processed items are further transported, they are lifted up out of the reactor by a rake (14) and guided onto a discharge chute (15).
