Abstract: A plug assist tooling assembly for a roll fed, post trim thermoforming machine in which a spider plate connecting plug assist rods is located below one or more support plates holding a clamping plate having an array of holes formed therein each defining a chamber each receiving a plug assist which chambers are sealed when sheet material is clamped by rings encircling the open top of each chamber to enable air pressure communicating to each chamber to exert forming pressure on the section of sheet material within each clamping ring. The support plates are fixed spaced from one of the main platens by standoffs fixed relative to the support plate or plates and the platen, the spider plate located in the same space.

Abstract: A secondary containment apparatus for storing a primary container is provided wherein the secondary containment apparatus is tilted into the vertical position to load the primary container. The secondary containment apparatus has a base member defining a liquid impermeable chamber, a support mounted in the chamber and a container catch mechanism for securing the primary container to the support when the secondary containment apparatus is in the vertical position such that the primary container is properly mounted therein upon returning the secondary containment apparatus to the horizontal position. A lid member is preferably provided which engages with the base member to enclose the primary container.

Abstract: An evaporative cooler body comprises a non-corrosive, insulative assembly of self-locating, self-jigging parts. Stand-off means are provided for increasing the effective area of the evaporative cooling pads and for improving air flow across the surface of and through said pads. An improved water distribution means permits sheeting of the water across the top surfaces of the evaporative cooling pads to obtain a more uniform distribution of water within said pads. Means are provided for interrupting water flow on the surface of the evaporative cooling pads and returning such water to the interior of said pad so as to increases the overall efficiency of the evaporative cooler. The evaporative cooler cabinet is comprised of a minimal number of reaction injection molded elements of high modulus urethane elastomer. The material insulates both sound and heat providing a quieter running and more cooling-efficient device. Color may be permanently molded into the cabinet.

Abstract: 1. Apparatus for protecting a pelagic vessel from attack by acoustic homing orpedoes comprising a vehicle to be towed submerged a substantial distance behind said vessel, an electroacoustic transducer mounted in said vehicle and having a forwardly directed directivity pattern, a source of constant amplitude oscillating electrical wave energy, means for modulating the oscillating frequency of said wave energy cyclically over a range inclusive of the operating frequencies of such torpedoes and at a linear rate slow enough to satisfy the energy requirement in the band pass of passive torpedo circuits and fast enough to satisfy the rise time of active torpedo discriminator circuits, and means for energizing said transducer with the modulated wave energy from said source.

Abstract: There is provided a direct nuclear pumped gas laser in which the lasing mechanism is collisional radiated recombination of ions. The gas laser active medium is a mixture of the gases, with one example being neon and nitrogen.
