Abstract: ABSTRACT OF THE DISCLOSURE    A system for the safe handling of pulverized coal, which system includes conventional coal pulverizing and drying equipment, with cyclones and bag filters added, the latter serving to separate the fine coal from the conveying gas (usually air); and explosion suppression and fire suppression systems, both of which later systems include conventional components. All three of these systems (coal preparation, explosion suppression and fire suppression) are so combined as to effect the grinding of raw coal whereby to dry and collect the pulverized coal in a oxygen containing atmosphere without property loss due to explosion or fire. A number of explosion detectors and associated extinguishers are strategically located throughout the coal preparation system so that when pressures slightly above operating pressure being to develop, the explosion extinguishers will be actuated not only to suppress the explo-sion but also simultaneously to shut down the coal preparation system. Similarly, fire detectors and associated extinguishers are also strategically located throughout the system so that when temperatures slightly above process temperature are sensed the extinguishers will immediately act to suppress the fire and simultaneously shut down the coal preparation system. Preferably the fire suppression system will go into actuation prior to the explosion suppression system and when this happens, the explosion suppression system may be shut down manually if the operator decides it will not be needed, whereby to avoid the expense of having to reload the explosion suppression system.

Abstract: ABSTRACT OF THE DISCLOSURE           An adjustable wall penetration framing member which is adjustable at any point by raising or lowering an adjustment screw and which prevents the infiltration of water and air into the interior of a building through the adjustable member.  The superior framing member not only excludes penetration of the elements when a substantial pressure difference exists between the inside and the outside of the building, but it also positions the weather seal in an internal elevated position which serves to prevent absorption of rain water and otherwise to isolate it from the elements so that rapid deterioration of the weather seal is avoided.

Abstract: ABSTRACT OF THE DISCLOSURE            A device for cleaning induction air for a combustion engine used as a power source in a lawn mower of the kind which is supported by means of a cushion of air is disclosed.  The present device adequately cleans induction air for the motor while avoiding the use of the hose and comprises a cylindrical chamber with tangential air inlet openings, an induction tube extending co-axially into the chamber,  and a filter element.          The chamber has an outlet opening remote from the inlet openings and from the entrance to said induction tube, this outlet opening is in communication through ducting with a position adjacent an air inlet port in the housing of the mower.  Thus, when the mower is in operation air enters through said tangential air inlet openings and makes a rotary motion within the chamber so that the air is partially cleaned as in a cyclone separator.  A portion of this partially cleaned air passes through the induc-tion tube and the filter element to the engine.  The particle-laden air passes from the chamber through the outlet opening and provides the air cushion for the lawn mower.

Abstract: IMPROVED CLOSED MIXING SYSTEM FOR   TENDING AGRICULTURAL SPRAYERS  Abstract of the Disclosure A closed agricultural chemical batching measuring and mixing system is disclosed for mount-ing to a sprayer tending truck.  The system includes a measuring tank on which a partial vacuum is drawn by opening a connection to the intake manifold of the internal combustion engine of the truck.  The measuring tank is in turn communicated to at least one manifold having numerous valve control inlets, all communicated to discrete agricultural chemical con-tainers which can include highly toxic liquid chemicals. At the inlet remote from the measuring tank, the manifold communicates to a supply of surfactant. Preselected amounts of the liquid chemicals are sequentially drawn by the partial vacuum through the valve controlled manifold and to the measuring tank in which they are accumulated.  The surfactant is then drawn through the manifold and into the measuring tank to flush the system.  As the chemicals and surfactant are drawn into the measuring tank, the fumes created by the chemicals in the measuring tank are drawn into the intake manifold of the engine and rendered substantially nontoxic.  After mixing of the liquid chemicals and surfactant in the measuring tank, the vacuum is broken and the batch is dumped through a dump valve at the bottom of the tank.  Simultaneously, a stream of water is discharged from a water storage tank on the tending truck through a conduit to a spray tank on a tractor spraying rig.  The measured batch is drawn into the stream of water at less than atmospheric pressure through an induction manifold interposed in the water conduit and diluted by the water.  Provision is made to introduce wetable powders into the stream of water in addition to the liquid agricultural chemicals.  Thus, a closed mixing system is provided for both liquid and powdered agricultural chemicals.
