Abstract: A method of introducing treatment agents comprising medicine or nutrients into a tree, involving the boring of holes above ground into the trunk of the tree. Homogeneous plugs of solidified polyethylene glycol (PEG) with such treatment agents mixed therein are molded and inserted into the holes in the tree trunk and sealed with wax. The dissemination time of the treatment agent into the tree trunk is controlled by selection of the PEG's used, with higher molecular weights PEG's taking longer to dissolve and disseminate the treatment agent into the transpirational flow of the tree being treated than the lower molecular weight PEG's. The method leaves no foreign material such as plastic casings or cartridges within the tree trunk after treatment.

Abstract: A snow tiller for ski slopes having rotating cutter bars with outstanding teeth. The cutter bars are each installed beneath a cover which directs the snow rearwardly to a snow smoothing comb. Each cover is adjustable in geometry to provide either greater or less angle of entry of the snow beneath the snow comb, and the change of angle is coordinated with changes in depth of snow cutting by the cutter bar teeth. A double acting hydraulic cylinder and ram assembly links cutter bar mounting frames, and is used to control the longitudinal angles of the cutter bars upon the snow.

Abstract: An evaporative device for cooling a stream of air for cooling a space into which the air is discharged.

The stream of air is cooled by one or more mist nozzles in the incoming air stream, the flow of water to which is controlled through analog or digital control devices, enabling cooling of the stream of air to the maximum permitted by psychrometric relationships without unnecessarily high humidity or overwetting of the evaporative pad.

Abstract: A method of dissipating heat from the interior of containers of harvested brine shrimp eggs to prevent overheating from spontaneous or environmental sources. Hollow convective members are installed embedded within the mass of eggs within the containers. The method helps in the use of larger, more efficient bags for brine shrimp eggs without increased mortality rates of the eggs.

Abstract: An inventive internal combustion engine adapted for an eight piston stroke operating cycle. The rate of comsumption of fuel and air mixture, and the pressure at which it is ignited and combusted, is enhanced by the addition of a holding chamber for fuel and air mixture which retains an initial intake charge of mixture to be later mixed with a subsequent intake charge before compression and combustion within the cylinder. The engine is therefore capable of greater power with given size cylinders. Conversely, the engine is capable of producing a target rate of fuel consumption and power output with smaller cylinders. The engine may also be designed to operate in a Diesel manner utilizing an appropriate hydrocarbon fuel.

The stream of air is cooled by one or more mist nozzles in the incoming air stream, the flow of water to which is controlled through analog or digital control devices, enabling cooling of the stream of air to the maximum permitted by psychrometric relationships without unnecessarily high humidity.

Abstract: An advanced chess game which has a game board having an upper surface for playing the advanced chess game and two sets of game pieces for use by a player and an opposing player. The rectangular playing surface provides additional playing squares over the standard chess game. Each set of game pieces includes the standard set of chess pieces from the standard chess game except that only five, instead of eight, Pawns are used. The sets each include game pieces of two new and different designs, one called a Checker and the other a Cavalry. While each of the standard chess pieces used operate in accordance with the rules of standard chess, the new Checker piece moves an unlimited number of spaces at a time in one of a forward, backward, left and right direction. The new and different Cavalry piece is similar to the standard Pawn in movement, but may additionally capture straight forward one square.

Abstract: A method of slip casting for the manufacture of ceramic items, wherein the wall thicknesses are accurately determined by providing confined slip pool samples which visibly solidify on an external portion of the plaster of paris mold being used. The solidification of the sample is indicative of the moist wall thickness of the object being molded, when the mold is decanted at that instant of still liquid slip.

Abstract: A sled to be pulled over snow by a skier, a snow shoer, or the like, with a waist attached, rigid towing member harness and a duffel container carried upon the sled. The sled has a plastic shell body with bottom runners designed to cause the sled to accurately follow the path of the skier.

Abstract: A safety device for cable sheave installations, which provides cable guide assemblies which block hands and the like from being drawn in to be injured between moving cables and sheave wheels. The cable guide assemblies are pivotally attached to the outside ends of arms in turn pivoted at their inside ends from the sheave wheel support structure. The cable guides also prevent injury and property damage from cable jump, by guiding cables with large approaching fleet angles directly onto the wheels.

Abstract: Devices and associated methods for removing scored edge strips from computer printout sheets. A base member of one device carries an open ended, outwardly opening, channel through which the edge strips and sheets are pulled together to separate the strips by drawing the score line against a tearing plate outstanding centrally within the channel. The tearing plate includes a blunt V-shaped portion to facilitate tearing. The device may be employed to simultaneously remove the edge strips from a single sheet or from a stack of several.

Abstract: An apparatus and method for final drying of harvested brine shrimp cysts preparatory to containerization, for subsequent storage and shipment. The device is portable, and may be installed upon the near shore of the shrimp bearing body of water, or upon shrimp harvesting vessels. A closed drying chamber contains a vertically arranged series of cyst drying trays, the cysts cascading downward from tray to tray by gravity assisted by vibration of the trays from top to bottom of the drying chamber. Conveying and lifting apparatus is associated with the chamber to permit the recirculation of the cysts until a sufficient degree of dryness is obtained. Heated air is introduced into the stationary drying chamber. The apparatus provides for final separation of any broken shrimp cysts still remaining.

Abstract: A method for filling and closing a package which is initially open on its upper side and has sealable plastic material about the periphery (2) of that side. The package is first conveyed to a location (6), where it is filled. Thereafter, a covering foil sheet (12) is sealed to periphery (2) to cover the open side. The package is brought to a standstill at the filling location (6), and filled through an opening (11) in a strip of the covering foil (7). The strip of covering foil (7) is then moved in a direction (10) lateral to the direction of conveyance (5) of the package, until the open side of package (1) is covered by the foil strip (7). A foil cover piece is then punched from the foil strip (7), leaving a new opening (11), and is sealed to the periphery (2) of the open side of the package (1). The sealed package (1) is then moved from filling location (6) by the conveyor belt (4).
