Abstract: A two stroke internal combustion engine with at least one dual piston, the cylinders of which are connected to each other by a combustion chamber on the cylinder head side. The engine can be charged on the crank chamber side with an air or air/fuel mixture by a turbo or supercharger. Both the leading and trailing pistons of the dual piston construction control the process of transfer of the air or air/fuel mixture through a transfer port from the crank chamber side of the cylinders to the combustion chamber side of the cylinder for the trailing piston as well as the exhaust process such that the exhaust process begins before the initiation of the transfer process. The engine can operate on either the Otto or Diesel cycles and use multiple fuels.

Abstract: A pin (18) is provided for attaching a connector or an adaptor (16) to a wiper blade (10). The pin (18) has a novel head (70) on one end portion which has spaced tangs or tabs (72) depending therefrom.

Abstract: A refrigerator includes a compressor, a condenser fan, and an evaporator fan simultaneously energized by a temperature control system which includes a thermistor located to sense the average temperature of the cabinet air and a potentiometer manually adjustable to a desired temperature set point. The on or run time of the compressor and fans is controlled by the thermistor sensed temperature with respect to the set point. The duration of the run time is measured by a resettable counter. The off time is adaptively controlled within a predetermined range which minimizes energy consumption while maintaining good temperature control. An off time counter, which is used to determine the duration of the off cycle, is incremented when the measured run time is less than a desired minimum, is decremented when the measured run time is greater than a desired maximum, and maintains the prior off time when the measured run time is within a desired range.

Abstract: A lock system for a container, such as a tool box or a storage cabinet which is locked by a padlock. Structure within the container mounts the padlock within the container with only a key insertion end of the padlock body exposed for access thereto.

Abstract: A high efficiency domestic furnace incorporates means for separating and neutralizing flue gas condensate. Acidic condensate from the flue gas products of combustion is neutralized by contact with neutralizing material in a housing through which the condensate is flowed. The use of the neutralizer in connection with a high efficiency domestic furnace permits discharge of the condensate directly to the household drain. The neutralizer is arranged to be self-flushing and defines a serpentine, series flow path and is arranged to discharge the neutralized condensate as a result of the entry of additional acidic condensate at its inlet.
