Abstract: A hydraulic platform and level correcting system used for a wide variety of lifting applications that require a steady, level lift in order to avoid damage to the lift and/or an object being lifted. The hydraulic platform is controlled by an electrohydraulic control system which includes a hydraulic pump under the control of an electric control circuit to provide the lifting force necessary for hydraulic platform operation as well as a device for automatically correcting the level of the hydraulic platform.

Abstract: Heat transfer is improved and maintenance down time is decreased by a method for collecting particulates on a hinged perforate strainer at the inlet of a sump pump in a circulating water system. An improved sump pump strainer apparatus is also disclosed.

Abstract: A device for removing the volatile components of a polymer in a polymer train includes a hollow pipe which defines an interior chamber, a pair of flanges mounted on opposite axial ends of the pipe, a heat jacket mounted on the pipe and disposed to surround the pipe, a plurality of band heating elements mounted on the outer peripheral surface of the heat jacket, and an arrangement of fin elements disposed in the interior chamber of the pipe to contact the polymer flowing through the pipe. Heat from the heating elements is distributed by the heat jacket over the axial length of the pipe and is transferred to the fin elements to heat the polymer flowing through the pipe. The fin elements may be in a cruciform arrangement within the interior chamber of the pipe. A method of removing the volatile components includes forming a thin film of polymer and heating and distributing the heat evenly on the thin film of polymer so that the volatile components may be vaporized.

Abstract: The flow rate of liquid being fed to a point of use is continuously monitored as is the liquid level in the feed tank by detecting the level in a liquid gauge member at two successive locations while feed from the tank is blocked, so that such detected data can be employed in a computer to output the flow rate and tank level.

Abstract: Two liquid comonomers are fed into a catalytic reactor through two separate concentric flow courses having pass through in a Tee-fitting connected to the reactor by a nipple. The two flow courses have spaced apart termination locations within the reactor and there is thereby avoided any possibility of commingling or cross-contamination of the two liquids at any time before they outflow within the reactor from their respective flow courses.

Abstract: A conventional evaporator of a cooling tower system is modified so that anti-corrosion additives are introduced into the cooling tower system in response to the flow of make-up water into the cooling tower to replenish the supply of recirculating water.

Abstract: Tube ends are received at opposite ends of a bore passage in a block of an electrically non-conductive material. Ferrules encircling the tube ends are compressed to effect a fluid tight seal of the tube ends and block and effective at pressures of about 650 psi. Plates are mounted to the block ends for applying compression force to the ferrule and the plate mounting involves low reactive force in the block.

Abstract: Ambient and localized sites within a room space are exhausted as required into a single fan unit and exhaust main. Flexible ducts connected to the main are positionable at various site locations and when one is used to for effecting exhaust at a site, the ambient exhaust to the main and the exhaust path of any other flexible duct is closed off so that exhaust flow in the system can enter only through the selected flexible duct thus maximizing the rapidity and facility with which undesirable gases present at the local site can be removed effectively and most economically from the room space.
