Abstract: A system and method for generating well qualified sales leads to a service provider, using a novel buckslip, brochure or coupon promoting a product or service not usually carried by a retailer. The buckslip has a universal product code (UPC) barcode which can be scanned at a retailer's point-of-sale device, along with the customer's retail loyalty card or other unique identifier that is linked to a database of customer contact information. The buckslip provides instructions to the customer to contact the service provider to purchase the service. In a daily process, the service provider sends a list of the customers who have purchased the service, to the retailer. The retailer then sends a list to the provider with contact information for interested customers who have not yet purchased the service, within a predetermined time period.

Abstract: The mechanization of a hot air engine cycle consisting of almost constant temperature compression, heat added from regeneration at constant pressure, heat added at constant volume, adiabatic expansion, and heat rejected to regeneration. Almost constant temperature compression is achieved by using a multi-stage-intercooled compressor. Heat is added at constant pressure by means of an exhaust gas to compressed air heat exchanger. Combustion heat is added at constant volume by means of a piston arrangement in the expansion cylinder. Adiabatic expansion takes place all the way to ambient pressure. The engine has dynamic braking by compressing air into storage to slow down the load. A clutch is used to disconnect the compressor, and the compressed air in storage is used to operate the engine. This results in an increase in maximum work output equal to the work of compression.

Abstract: The mechanization of a hot air engine cycle consisting of constant temperature compression, heat added from regeneration at constant pressure, energy stored, heat added at constant volume, adiabatic expansion, stored energy used, adiabatic expansion, and heat rejected to regeneration. Constant temperature compression is achieved by using a multi-stage-intercooled compressor. Heat is added at constant pressure by means of an exhaust gas to compressed air heat exchanger. Energy is stored in the compressed air tank. Heat is added at constant volume by means of a two-piston arrangement in the expansion cylinder. Adiabatic expansion takes place. Energy from storage is used. Adiabatic expansion takes place all the way to ambient pressure. The displacement of the resulting engine can be varied while the engine is running. The engine has dynamic braking by means of an alternator charging a battery. The battery power is used to drive a compressor.

Abstract: Improvement to an internal combustion engine with heat exchanger to allow changing the displacement of the engine while the engine is operating by adding compressed air storage container 36, movable wall 11, fixed stop 6, bias spring 38, adjustable stop 40, adjustable stop controller 44, telescoping connecting rod 25, and pusher piston 15. In the resulting engine, compressed air from compressed air storage container 36 moves through heat exchanger high-pressure side 8 and on into cylinder 12. When the desired amount of air is in cylinder 12, inlet valve 10 closes, fuel is then added, burned, and expanded. When the pressure in cylinder 12 decreases, movable wall 11 moves back down against fixed stop 6 as expansion continues. Telescoping connecting rod 25 and pusher piston 15 enable almost constant volume heating, and keep a vacuum from forming at low power operating conditions.

Abstract: The Mechanical Freezer of this invention closely approaches an ideal freezer cycle composed of constant temperature compression, expansion, and constant volume heating (load transfer) by using power piston 106 that power input shaft 50 moves up and down and displacers 104 and 105 that are moved by cam 108. When power piston 106 moving up and additional displacer 105 moving down come together, fluid is forced through additional heat sink 41 where it is cooled as it is compressed. When additional displacer 105 and primary displacer 104 come together, fluid is forced through primary heat sink 40 where it is cooled as it is compressed. After compression, the cooled fluid is expanded by power piston 106 along with displacers 104 and 105 moving down. When displacers 104 and 105 then move up, fluid is forced through load 30 and load 30 is cooled.
