Inventor: KINNEY OHLER L JR
IPC: F28F21/06
Filed: 1988-08-06
Abstract: A crossflow cooling tower (10) has a number of fill structure sections (46) which are arranged at equally spaced intervals around the entire perimeter of a central plenum (52) that receives generally horizon­tal currents of air simultaneously from all of the fill structure sections (46) and causes the air to be discharged in an upwardly direction out of the tower (10). In one embodiment, the tower (10) is provided with four upright fill structure sections (46) disposed in a square arrangement in horizontal view, and a number of the towers (10) may be located adjacent each other in a side-by-side diamond-like arrangement so that each air inlet face (48) of each tower (10) readily communicates with the atmosphere. Both the hot water distribution basin (14) and the cold water dis­tribution basin (16) are formed as integrally molded, one-piece components, and four upright air baffle corner supports (56) carry the weight of adjacent fill structure sections (46) as well as the load presented by the overhead hot water basin (14), thereby minimizing the need for additional supporting members, bracing or casings to provide necessary structural integrity.

Abstract: High permeability zones in a subterranean formation are reduced in permeability by the time-delayed gelation of water soluble polymers in such formation with alkoxy amine esters of boric acid which slowly hydrolyze. Boric acid resulting from the hydrolysis converts to the borate ion which crosslinks the polymers to form gels.

Abstract: A double-ended booster liquid pump comprises first and second motor driven impellers (3, 4) located at respective inlet ports (1, 2) to the pump. A third motor driven impeller (6) is arranged to be supplied with liquid from the respective inlets (1, 2) through the first and second impellers (3, 4). Liquid bypass means (8) is provided between a liquid inlet to the third impeller (6) and an outlet port (7) from the pump and valve means (9) is arranged to close off the bypass means (8) when the liquid flow through the third impeller (6) is at a relatively low level.

Abstract: The framework assembly arrangement is assembled from frame profile sections (10) and connectors (20) and is used in switchboard construction, for racks and storage devices, in domestic installations, for apparatus cabinets and the like. On the quadrilateral hollow profile - preferably square - the one side (16) has a longitudinal slot (12) and at least the two adjacent sides (18) each have opposite perforations (14) at a regular pitch. The detachable connectors (20) have two pairs of limbs (24), which are located opposite one another at a variable distance and which can be inserted in a positively locking manner into the interior of the profile (10). By spreading (spreading devices 30), the limbs (24) are made to rest on opposite inner walls of the profile. At the same time, latching cams (28) engage with the perforations (14), as a means of locking against longitudinal movement. A transverse score on the outer sides of the limbs and on the inner sides of the profiles can also be used for the same purpose. Various variations of the profiles, connectors and specific embodiments of the spreading devices (30) are described.

The ends of the arms are separated by a distance that is greater than the thickness (T) of the web. When placed over the end cap of a beam, the apparatus is turned about the axis of symmetry (28) until the two arms contact opposing sides of the web, thereby locating the desired web center. The upper portion of the apparatus is preferably made from a transparent material.
