A candle embedded with metal particulates is provided that includes a candle body, one or more wick wells, and one or more wicks. The candle body is formed of a moldable and combustible material, such as paraffin or wax. Additionally, the candle body includes a plurality of metal particulates disposed within the moldable and combustible material. Each wick is disposed within a wick well which is essentially a region of moldable and combustible material that is devoid of metal particulates so as to promote more uniform burning of the candle. Preferably, the metal particulates are aluminum wedge shaped flakes. The function of the metal particulates is threefold: 1) they maintain the shape and size of the candle throughout its burn life; 2) they conduct heat from the flame throughout the candle body to permit melting and flowing of liquid wax throughout the candle body to the wicks; and 3) they reflect the candle flame light from the top surface of the candle. Similar to a traditional candle, one or more wicks may be disposed substantially vertically within the candle body. Alternatively, one or more plane cloth wicks may be disposed substantially vertically in the candle body with the top edge extending above the surface of the candle body to form a continuous line of flame when lit. In an alternative embodiment, a metal particulate candle cap is provided for use on the top of a large diameter traditional candle in order to promote more efficient use of wax in the traditional candle while being burned.

Candle with embedded metal particulates

A regenerative gas-to-gas heat exchanger having a plurality of superposed spaced, parallel beds of confined metal flakes adapted for gas flow therethrough; four gas plenums surrounding the beds, each plenum communicating with one side only of all the beds; means for supplying a relatively hot gas to one plenum, means for supplying a relatively cold gas to an opposite plenum, each of the remaining plenums communicating with a separate outlet; and sliding gate valve means in each plenum adjacent one side of the beds, means for moving the gate valve means to a first position and to a second position for controlling the directions of gas flow and alternately extracting and releasing heat therefrom.

Regenerative gas-to-gas heat exchanger

The invention comprises a mulch sheet to be placed on the soil around the stalk of a plant. The mulch comprises aluminum flakes bonded to a woven mesh which aluminum flakes will reflect rays of the sun upward to the underside of the leaves and the mat will hold moisture in the ground which has seeped into the ground through the porous mat. The aluminum flakes are applied to the upper tacky surface of a thermoplastic woven mat and are pressed into the tacky surface to hold them in position after the thermoplastic, fibrous mat cools to freeze the flake in place. In additional embodiments, it is sometimes appropriate to make a pod containing a seed which will be secured to the underside of the matting in the open hole. A layer on the underside of the mat could include a layer of fertilizer.

A rotary engine includes a housing having a cylindrical internal surface on which seals are supported to prevent the flow of gases from spaces between two rotating pistons on separate but concentrically-arranged shafts. Three sets of gearing control relative rotation of the pistons which move toward and away from each other to compress gases between the pistons. A drive shaft is connected by the first gear set to a first of the concentrically-arranged shafts. The drive shaft is also connected by a second gear set to the other of the concentrically-arranged shafts. The third gear set, comprised of non-circular gears, connects the drive shaft to an output shaft.

Rotary engine

A compound internal combustion engine having an efficiency materially higher than that of an engine operating on the conventional Otto or Diesel cycle. This is accomplished by using the heat of the exhaust gases to compress air, with or without the addition of fuel, which is then injected into the cylinder or cylinders of the engine just prior to ignition. In this manner, less heat is rejected from the overall cycle with improved efficiency. In the preferred embodiment of the invention, a portion of the unused heat energy in the exhaust gases is used in a unidirectional energy converter to compress air or an air/fuel mixture which is then injected into the cylinders of the engine. The engine, whether it should operate on the Otto or Diesel cycle, does not compress gas on the upstroke of the piston until the compressed gas from the unidirectional energy converter is injected into the cylinder.

A turbocharger for internal combustion engines comprising a unidirectional energy converter having a closed, continuous loop passageway containing a plurality of freely-movable, unrestrained bodies which travel around the passageway in one direction only. In one region of the passageway, successive bodies are propelled in one direction around the passageway by exhaust gases from an internal combustion engine. In another region of the passageway, the kinetic energy of the propelled bodies is used to compress a gas, which can be mixed with fuel. This compressed gas is then forced into the cylinders of the internal combustion engine; whereupon the bodies are again propelled around the passageway to repeat the cycle.

Method for converting one form of energy into another form of energy by isobarically heating a gas, adiabatically expanding the gas while converting the heat energy of the gas into the kinetic energy of a moving body, converting the kinetic energy of the moving body into another form of energy, and approximately isothermally compressing the gas to a higher pressure. Improved efficiency is achieved by virtue of the fact that this system employs approximately isothermal compression, which is preferably achieved by injecting liquid into an adiabatically-expanded gas, thereby effecting a thermodynamic cycle which more closely approximates the efficiency of a Carnot cycle.

Method for converting one form of energy into another form of energy

Thermal energy is converted into rotational energy by using the expansion of a fluid medium to propel a plurality of pistons within at least one continuous, closed-loop passageway mounted on a rotatable platform. In at least one region of the passageway, the pistons must move inwardly against centrifugal force as the platform rotates. In at least one other region of the passageway, the pistons are moved outwardly under the influence of centrifugal force. Means are provided for imparting force to successive ones of the pistons to propel them against centrifugal force in said one region; while means are provided for converting the energy of pistons moving outwardly under the influence of centrifugal force in said other region into rotational energy. This rotational energy is used to drive gears mounted on the platform which mesh with a stationary gear carried beneath the platform to cause rotation of the platform about its rotational axis. The energy used to accelerate the pistons is thereby converted into rotational energy of the platform. In one embodiment of the invention, at least two continuous, closed-loop passageways are used on the platform in order to prevent an unbalanced condition. In another embodiment of the invention, a single passageway is used on the platform comprising two essentially straight portions on opposite sides of the axis of rotation of the platform interconnected at their opposite ends by curved portions, also on opposite sides of the axis of rotation of the platform. By forcibly rotating the platform in reverse, the invention can be used as a compressor.

Unidirectional energy converter

Heat pump apparatus employing a continuous loop passageway containing a plurality of freely-movable, unrestrained bodies. The bodies are accelerated around the passageway in one direction by adiabatic expansion of a fluid between the bodies in an expander region of the passageway. The expanded, cooler fluid is discharged from the passageway via one or more vent-intake ports in the passageway beyond the expander region. Warmer fluid enters the passageway via said ports and is compressed between the propelled bodies in a compression region of the passageway, thereby raising its temperature from a first temperature (e.g., the temperature of the outdoor atmosphere or an industrial waste heat stream) to a second temperature higher than the first. The compressed, warmer fluid is thereafter passed through a heat exchanger to extract heat. In passing through the compression region the bodies are decelerated and they then pass through a thruster region of the passageway wherein a force is applied to the bodies to counterbalance the external forces acting against the bodies as they move around the loop passageway. From the thruster region the bodies pass to the expander region to repeat the cycle. From the heat exchanger the fluid, typically together with additional compressed fluid from an external source, is introduced into the expander region to again accelerate the bodies.

Improvements in apparatus for converting one form of energy into another form with the use of an essentially closed, continuous loop passageway containing a plurality of freely movable, unrestrained bodies. Force generated by expansion of a gas is applied to successive bodies in one region of the passageway to propel them around the passageway in one direction. At another point in the passageway, at least a portion of the kinetic energy of the propelled bodies is converted into another form of energy. Each body, before being propelled around the passageway, enters a compressor section where it compresses the gas in the passageway, the compressed gas being bled off through a check valve where energy is added to it before it is used to propel a body around the passageway in the expander section which immediately follows the thrustor section. The invention is characterized by the addition of conduits connected to the compressor and thrustor sections to regulate the pressures therein and prevent noisy operation, wasted kinetic energy and the possibility of having bodies move backwards from the thrustor section into the compressor section.
