Abstract: A refrigerated case includes a housing including an interior display volume and a heat exchanger. The heat exchanger includes a circuit defined by a heat exchanger section including a plurality of tubes that define a flow path, a reheat section including a reheat tube, and a connecting tube fluidly connecting the flow path of the heat exchanger section with the reheat tube. Air flows over the plurality of tubes of the heat exchanger section and rejects heat to a refrigerant flowing through the plurality of tubes to heat the refrigerant. The heated refrigerant then flows through the reheat tube. As the air passes over the reheat tube, the air accepts heat from the heated refrigerant flowing through the reheat tube.

Abstract: A battery pack for a power tool includes a casing housing rechargeable cells. A receiving bay in the casing receives slide-in parts of the power tool and of a recharging stand, to retain the battery pack. A pair of primary electrical contacts is located in or adjacent the receiving bay. A recess opens into the receiving bay. A supplementary electrical contact is located within the recess, and a user-manipulable catch is also located in the recess alongside the supplementary contact. That is, a single recess houses both the supplementary contact and the mechanical catch. The supplementary contact is usable when recharging the battery to relay battery temperature information to a recharging stand, but has no function when the battery pack is attached to the power tool. The catch, useful in retaining the battery pack on the power tool, has no function with the recharging stand.

Abstract translation: 用于电动工具的电池组包括容纳可再充电电池的壳体。 外壳中的接收槽接收电动工具和充电台的滑入部分，以保持电池组。 一对主电触点位于接收槽中或邻近接收槽。 凹槽通向接收槽。 辅助电触点位于凹槽内，用户可操纵的卡扣也位于辅助触点旁边的凹槽中。 也就是说，单个凹槽容纳辅助触点和机械卡扣。 当对电池进行充电以将电池温度信息中继到充电台时，补充触点可用，但是当电池组连接到电动工具时，辅助触点无功能。 用于将电池组固定在电动工具上的卡扣无法与充电支架一起使用。

Abstract: A refrigerated merchandiser system (10) includes a compressor (20), a condenser (30), a display case (100) having an evaporator (40), an expansion device (50), and an evaporator pressure control device (60) connected in a closed refrigerant circuit via refrigerant lines (12, 14, 16 and 18). The evaporator pressure control device (60) operates to maintain the pressure in the evaporator at a set point pressure so as to maintain the temperature of the refrigerant expanding from a liquid to a vapor within the evaporator (40) at a desired temperature. A controller (90) operatively associated with the evaporator pressure control device (60) maintains the set point pressure at a first pressure for the refrigerant equivalent to a first refrigerant temperature during a first refrigeration mode and at a second pressure for the refrigerant equivalent to a second refrigerant temperature about 2 to about 12 degrees warmer than the first temperature during a second refrigerant mode. The controller (90) sequences operation between said first refrigeration mode and said second refrigeration mode.
