Abstract: The trailer comprises a transport base with road wheels and a floor on which is mounted an elongate shell having side walls and a roof, the planform of the shell corresponding to the planform of the base. Separate, removable fasteners connect the shell to the base. Jacks are connected to the aft end of the shell to raise it out of contact with the base when the fasteners have been removed. Extensible rollers at the forward end of the shell are lowered to contact the floor of the base. The base can then be moved forward to remove it from under the shell so that it can be used as an open flat bed trailer. Other jacks are connected to a forward portion of the shell, to support the shell when not in use. An assemblage of partitioning components is provided to provide compartments for transporting a pair of horses and is removable to provide an open cargo space when needed.

Abstract: The system is intended primarily for use in multi-engined aircraft although it has great utility in any installation having an engine and a generator driven thereby. A kit for each engine includes a generator drive train connected to the engine to be driven thereby, a driving formation for connection to a generator, and a coupling or clutch in the drive train to decouple the generator in case of mechanical or electrical failure. Signal means may be located in the cockpit in the pilot's field of view to indicate generator failure. A switch operable by the pilot in response to the failure signal acts to remotely cause decoupling of the generator. The active signal operates means to deactivate any other decoupling switch to prevent mistakenly decoupling a properly functioning generator. Cross-connection switch means are connected to all engines and generators and may be actuated to electrically connect an active generator to the engine having the decoupled generator.

Abstract: Method and apparatus for controlling the amount of outside air introduced into a given space being ventilated as a function of the oxygen content of the air in the space to minimize the energy expended in heating or cooling air flowing through the space while maintaining the oxygen content of the air above that required for the well-being of humans occupying said space. A fuel cell produces an electric current the magnitude of which is a function of the partial pressure of the oxygen present in the air surrounding the fuel cell. The output of the fuel cell is applied to a control circuit which applies control signals to the motor control circuit of a damper motor to admit outside air when the partial pressure of the oxygen in the occupied space falls to a predetermined minimum level and to exclude outside air and to recirculate return air when the partial pressure of the oxygen in the space rises to a certain maximum level.

Abstract: Method and apparatus for regenerating a diatomaceous earth filter cake of a pressurized liquid filter system by liquidizing the diatomaceous earth filter cake formed on filter elements in the filter chamber of the system; by uniformly mixing with the liquidized diatomaceous earth the insoluble particles, or impurities, removed by the filter cake from liquid that has passed through the cake; and by reforming the fluid cake with the impurities uniformly distributed throughout the filter cake. The liquidizing of the filter cake and impurities and mixing of the diatomaceous earth and impurities result from oscillations induced in the liquid in the filter chamber by several cycles of rapid reversal of the flow of liquid through the filter chamber.

Abstract: A compound splint, primarily for use after nasal surgery, prevents edema fluid from splaying the bones apart so that they will grow back together and includes a base layer of adhesive tape applied directly to the nose, a secondary component of flexible material adhesively secured to the base layer and having a multiple loop formation on its outer face, and a primary restraining component. The latter includes a panel of malleable metal and a layer of fabric secured to one face of the panel, the fabric having a multiple hook formation. In use, the primary component is applied to the central portion of the secondary component, engaging some of the hooks and loops. The side portions are then pressed inwardly against the sides of the nose to the desired final shape, engaging the balance of the hooks and loops. Thus the primary component is securely anchored in place and prevents any change in size or shape of the traumatized nose during recovery.
