Abstract: A particulate material drying apparatus and method including a pulse combustor and an associated combustion chamber. Fuel and combustion air are introduced to the combustion chamber whereby the combination of the pulse combustor and combustion chamber generates a pulsating flow of hot gases. A material feed introduction chamber receives the hot gases and material to be dried is delivered into the introduction chamber for contact therein with the flow of hot gases. A drying chamber is connected to the introduction chamber for receiving the mixture of material and hot gases exiting from the introduction chamber. The drying chamber comprises an enclosing wall, a porous inner wall spaced inwardly from the enclosing wall, and an annular space defined between the enclosing wall and the porous inner wall. Fluid under pressure is introduced to the annular space whereby the fluid passes through the porous inner wall and deters build-up of material on the inner surface of the porous inner wall.

Abstract: A golf ball construction comprising a core and cover, the ball defining an equator forming a first great circle extending over the cover surface. At least two additional great circles extend over the cover surface and intersect the first great circle, the additional great circles being spaced apart equally with respect to each other whereby the ball surface is divided by the combination of the first great circle and the additional great circles into a plurality of discrete symmetrically arranged surface areas. A separate array of spaced-apart dimples is formed on the cover surface within each of the discrete surface areas, each of the arrays covering substantially completely the cover surface in each discrete surface area. Channels are formed exclusively within each area and extend between adjacent ones of the dimples in each area, a channel extending from each dimple to every other dimple adjacent thereto. None of the channels cross any of the great circles.

In this regard, it is desireable to maintain the major portion inner layer(s) of a firefighting garment unbound to terminal ends of the outer layer so that it may more easily shed water, soil and contaminants.

Abstract: The fueling station consists of a vacuum insulated storage vessel for storing a large quantity of LNG at low pressure. The LNG is delivered to one of two relatively small volume fuel conditioning tanks where the pressure and temperature of the LNG can be raised or lowered as dictated by the needs of the system. The pressure and temperature in the fuel conditioning tanks are raised by delivering high pressure natural gas vapor thereto from a high pressure bank. The temperature and pressure can be lowered by venting natural gas from the fuel conditioning tanks and/or delivering LNG thereto. The fuel conditioning tanks are connectable to a vehicle's fuel tank via a fill line to deliver natural gas and LNG to the vehicle and to vent natural gas from the vehicle to the fueling station.

Abstract: The convertible wagon of the invention includes a handle that can be pivotably attached to a latch assembly on the front of the wagon body or can be snapped in an upright position into a locking assembly on the back wall of the wagon. The wagon can be pulled when the handle is attached to the latch assembly and can be pushed when the handle is snapped into the locking assembly. A removable panel separates passenger and storage compartments within the wagon body.

Abstract: The disclosed device relates to an improved system for mounting a game playfield within a game cabinet. The device provides pivotal and sliding movement of the playfield with respect to the cabinet while allowing quick removal of the playfield entirely from the game cabinet. The game cabinet is provided with a groove on each side thereof and spring-biased pivot pins are mounted on the playfield for travel within a respective groove in the cabinet.

Abstract: A golf ball defining a spherical outer surface and a plurality of spaced-apart dimples formed in the surface. The dimples comprise a central raised portion and a surrounding depressed portion with the depressed portion having a lateral dimension along any straight line extending through the center of the central portion and from one outer edge to the opposite outer edge of the depressed portion. The maximum depth of the depressed portion is from 0.008 to 0.015 inches and the raised portion extends outwardly from the depressed portion to the position of the spherical outer surface. The maximum lateral dimension of the raised portion, measured parallel to the spherical outer surface, is less than one-half the minimum lateral dimension of the depressed portion. The total effective volume of the dimples comprising the cumulative volume occupied by the depressed portions of all dimples formed in said surface is greater than 0.021 cubic inches.
