Title: Combustion-powered refrigeration with decreased fuel consumption
Inventor: SCHORR HANS P
IPC: F25B27/02

Granted: 1991-11-19
Abstract: Abstract:           COMBUSTION-POWERED REFRIGERATION WITH DECREASED FUEL CONSUMPTION            In refrigeration systems wherein the refrigerant compressor is driven by a prime mover powered by combustion of a fluid fuel, a notable saving in fuel consumption is achieved by utilizing waste heat in the hot exhaust gases from the prime mover in an absorption refrigeration unit that chills a coolant stream circulated to the condenser for the compressed refrigerant.   Existing combustion-powered refrigeration systems can be improved by adding a lithium halide absorption unit to utilize heat in the exhaust gases to produce refrigeration that is used to condense the compressed refrigerant.  A combustion turbine coupled to a centrifugal compressor is a preferred combination of prime mover and refrigerant compressor for economically producing tonnage refrigeration.

Abstract: ABSTRACT        A mailbox provided with a first signal flag mounted for rotation between a first position indicating the presence of mail in the box to be picked up by the mail carrier and a second, neutral position is disclosed.  A flange depending from the first signal flag is adapted to frictionally engage a portion of the mailbox door when the first signal flag is in the first position thereby retaining the first signal flag in the first position. When the mailbox door is opened, for example, by a mail carrier, the frictional engagement is broken and gravity causes the first signal flag to rotate to the second, neutral position.  The mailbox is provided with a second signal flag mounted for rotation between a first position indicating that a mail carrier has opened the mailbox door to insert mail and a second, neutral position.  The second signal flag has a depending flange adapted to be engaged by a portion of mailbox door when the second signal flag is in the neutral position, as the mailbox door is moved from a closed position towards an open position.  Continued movement of the door towards the open position causes rotation of the second signal flag to the first position where it can be frictionally held.  In one embodiment, the mailbox door and the first and second signal flags are mounted for rotation about a common axis.

Abstract: Abstract A container chassis is supported at one end by a movable bogie unit or "slider" mounted below it, and has a sliding bolster unit mounted above it to accommodate a heavy twenty foot cargo container. Retractable roller mechanisms on the bogie unit and on the bolster unit are urged against the chassis to permit easy placement of a unit at a desired position along the chassis, and a releasable coupling between the slider and the bolster allows the bolster to be moved along the chassis by the slider.  Protocols are described for moving a container between a first position centered on the chassis and a second position flush with the rear of the chassis.  In a preferred embodiment, the front portion of the chassis is elevated with respect to the rear portion, so that the bolster slides along a region lower than the front.  With the bolster in its rearmost position, the chassis accommodates a forty foot container.
