Abstract: An extrusion apparatus includes a slot-type cooling table over which elongated extruded members move laterally. A plurality of side-by-side blower units are located beneath the table to develop a blanket of air through which the aluminum extruded members pass. Each unit includes a motor-driven tubular air blower having a tubular outlet duct. A rectangular discharge nozzle is connected to the air blower and spans the extrusion line and also extends along a predetermined length of the extrusion conveyor. A plurality of adjustable louvers are connected within the nozzle to uniformly disperse the air from the tubular outlet duct into a square uniform curtain of air which passes upwardly over the conveying line and the metal extruded member on the conveyor. The louvers direct the air directly perpendicular to the extrusion and/or partially on-line with the hot extrusion. This produces high quality, uniform characteristic in the aluminum extruded member.

Abstract: A sandal is provided with an inside arch and ankle stabilizing flange which forms an integral part of a one-piece molded bottom without a separate inner sole. The flange is smoothly curved and extends upward along the arch side for a longitudinal length from a point adjacent the side of the ankle stabilizes the ankle joint by preventing it from rolling inward toward the walking surface thereby providing an unusually high degree of security for an open shoe. The footbed of the molded bottom conforms to the plantar surface of the normal foot while walking or at rest. Both the bottom footbed and the upper pattern including the inner longitudinal arch flange are designed to allow for the anatomical and functional differences between the inside and outside longitudinal arch areas of the normal foot, and act to discourage the tipping of the ankle toward the inside of the foot, resulting in pronation.

Abstract: Disclosed is a method, a system and an improved butterfly valve usable therein for recovering energy from a continuous supply of hot pressurized particulate-laden flue gas.

Abstract: A firearm especially for firing large calibre rounds such as rubber bullets and having a rotary magazine which is rechargeable at any stage of depletion. A loading arm serves to guide rounds through an inlet opening in the magazine, in such a way that they are received into corresponding locations in a rotating carrier, and the carrier rotates forward one position with each additional round. Until the penultimate round, the guide means is locked to the magazine body. In this position, it obstructs further movement of the first-inserted round and thus prevents insertion of the final round. Mechanism is described by which, on insertion of the final round the guide means automatically unlocks from the magazine body and locks to the rotating carrier. In this condition it serves to keep the first inserted round locked in the magazine as it completes a full rotation to come opposite the inlet opening once more.
