Abstract: A cooling coil arrangement for a cylindrical tower provides coverage of a larger area of the cylindrical footprint of a cooling tower to enable more economical usage of the vertical tower storage capacity for ice thermal storage, which coil arrangement has a plurality of coils arranged in multiply arranged planes with serpentine layouts of each tubing length generally having a vee-shaped layout in each plane between the longitudinal axis of the tower and the tower housing, which tubing lengths are provided in each sector of each plane normal to the axis and having a tubing length therein, and the manifolds coupling the tubing lengths to inlet and outlet ports for circulating coolant fluid through the tubing lengths to cool the phase change fluid in the cooling tower, and a plurality of the serpentine tubing lengths vertically aligned and preferably arranged with the tubing section of one u-shaped segment of a first tubing length in vertical alignment with the gap of another of the tubing lengths which provide

Abstract: An apparatus and method for cooling, air which apparatus includes an indirect evaporative cooler, an indirect contact chiller, a reheat coil component, an ice-thermal-storage component and an ice-manufacturing refrigeration chiller to provide alternative air-flow paths and alternative component combinations. Alternative fluid-flow paths are provided through electable combinations of the several components to effect the desired lowering of air temperature, relative humidity and air density in the cooled air.

Abstract: The present invention describes a method of controlling the head pressure in a refrigeration or air conditioning system in order to maintain the internal discharge pressure and discharge line pressure substantially equal. The method consists of the steps of measuring the suction pressure of the working fluid, calculating the internal discharge pressure of the working lfuid by multiplying the suction pressure by the internal pressure ratio of the compressor, measuring the discharge line pressure of the working fluid and then comparing the internal discharge pressure to the discharge line pressure. If the difference between the internal discharge pressure and discharge line pressure is greater than some allowable tolerance, the capacity of the condenser is adjusted to equalize these two pressures.

Abstract: Accordingly, a display system is provided whereby visual elements can be independently transported not only around but also parallel to the display axis. The display comprises a central shaft; carriages mounted along the length of this shaft; and visual elements borne by the carriages. Each carriage has a circumferential drive train which can propel it around the shaft, and an axial drive train engageable with a visual element such that the visual element can be passed generally parallel to the shaft from one carriage to an axially adjacent carriage. Ideally, the system is controlled by a computer system which may be programmed to move the carriages and visual elements in complex configurations.

Abstract: A clip comprises a lower leg at right angles to a shank and two upper legs defined by a slot extending upwardly from said shank. The shank is disposed in a slot in a connecting beam disposed between the ends of adjacent panels, and the lower leg of the clip is secured to a joist member before the adjacent panel is secured to the panel already in place. Upper and lower facing sheets on each panel extend beyond the insulating panel core and envelop respective edge portions of the connecting beam for attachment thereto.

Abstract: An insulated building panel includes a core and overlapping skins, the interior skin at the panel's bottom covering a panel foot plate and the exterior skin at the panel's bottom covering the foot plate and extending beyond to form an erection stop. End panels have relieved core areas for receiving bearing members associated with a wall splice bearing post, and double parallel spaced header beams have offset splice areas within a several panel wall section. Two end panels include improved end structure for forming an improved corner at the panel's intersection. Methods are provided for making and erecting a multiple panel wall section.
