A fixed pitch propeller has blades that are not solely dependent on the blade angle dictated by the helical path of the blade tip. An outboard portion of the blade has a range of blade angles that are relatively flat to operate most efficiently at lower aircraft speeds. An inboard portion of the blade has a range of blade angles that are relatively high pitched to allow efficient operation at higher aircraft speeds

A cabinet type enclosure, preferably in the form of a cart, which is adapted to be connected to a source of refrigeration for refrigerating a plurality of food items on a plurality of meal trays positioned in the enclosure has a plurality of thin, generally horizontal fixedly mounted heater shelf members extending into the enclosed space from one side wall thereof. The heater shelf members are adapted to be moved relative to and under hot food containers positioned on the trays to heat same. The enclosure also has pairs of tray guides on its opposing side walls. The meal trays have integral transverse abutment means which extend over a portion of the tray surface at a location above the surface. The transverse abutments cooperate with a container for hot food placed on the tray between the abutment means for preventing movement of the hot food container past the transverse abutment means by frictional contact with the heater shelf as the tray is moved into or out of the enclosure and relative to the heater shelf along the tray guides. The heater shelf members are positioned so that they will pass between the tray surface and the bottom of the abutment means. A ramp-like end on the heater shelf will engage and lift the chamfered bottom of a container to be heated so that the container will be gently lifted upwardly onto the heater shelf as the tray is moved to a position overlying a heating element on the heater shelf. The apparatus is particularly useful for inflight feeding as well as for institutional feeding.

Apparatus for selectively heating an individual food item in a

A system is disclosed for use in connection with a conventional Otto or four cycle, multi-cylinder, internal combustion engine with the system being adapted to selectively disable half of the operating cylinders of the engine whereby substantial fuel economies can be realized. The present system is adapted to be used as an attachment on a conventional automotive engine and is equally applicable to four, six, and eight cylinder engines. The system disables selected cylinders by both inhibiting flow of fuel to the cylinder and disabling the exhaust valve in an open condition so that the disabled cylinder will, in effect, be free wheeling in that it does not use fuel or produce unused compression which must be overcome by the remaining cylinders.
