Abstract: An open top refrigerated display case having an ambient air automatic defrost system and a method of operating such a case. A single air conduit extends in a U-shaped formation along opposing side walls and the bottom wall of the display case. The air conduit has openings at both ends in the location of the upper portions of the side walls. Arranged within the air conduit is at least one reversible fan and a set of refrigeration coils. During a refrigeration cycle the fan circulates air through the air conduit in a first direction towards the refrigeration coils. When frost buildup within the display case has reached a certain level, the system is switched to a defrost cycle. During the defrost cycle, the fan circulates the air in the opposite direction through the air conduit and draws in ambient air from outside of the display case. Since such ambient air is of a higher temperature than the normally refrigerated air, it serves to defrost the system.

Abstract: A device of the known type comprising an annular series of coil-guide blades intended to receive pre-wound coils to be inserted into stator slots, an annular series of wedge-guide blades surrounding the series of coil-guide blades and terminating a short distance before the free ends of the coil-guide blades in such a way as to allow the stator to rest on the free ends of the wedge-guide blades by disposing it about the coil-guide blades and a thrust member which is slidable through the series of coil-guide blades for inserting the coils into the stator slots.

Due to this characteristic, when the stator is pressed on the free ends of the wedge-guide blades and fixed in position for the insertion of the coils, the said free ends of the wedge-guide blades are automatically disposed at a distance from the free ends of the coil guide blades corresponding to the length of the stator.

Abstract: The present invention describes an extraction device for removing components, such as leaded integrated circuit packages, from a printed circuit board to which their leads are soldered. The device, under operator control, is designed to captivate the component and to apply to it an extraction force which has a predetermined magnitude independent of the operator's judgment. Accordingly, when all of the component solder joints at the printed circuit board have been sufficiently reflowed, the device automatically withdraws the component from the board into itself. Damage to the board or the component as a result of the extraction process is virtually eliminated through the use of the device.
