摘要： The pneumatic tool includes a housing which encloses a majority of the pneumatic tool. The housing is comprised of a body and a handle depending from the body and defining an input air passageway. A reversing valve lies partially disposed within the housing, intermediate the body and the handle. The body defines a preferably cylindrical motor cavity communicationg at its bottom with the input air passageway and at its top with an exhaust passageway located above the motor cavity. A pneumatic motor is disposed within the motor cavity. The pneumatic motor can include front and rear plates, a rotor rotatively suspended between the plates, and a cylinder disposed between the plates and in sealed engagement thereto. The cylinder has an upper portion with an exhaust port communicating with the exhaust vent and a lower portion with an air inlet communicating with the input air passageway to provide a substantially diametral airflow path through the motor.

摘要： A battery pack has a housing with a plug portion mateably receivable in a socket of a battery-powered power hand tool on which the battery back is designed to be mounted. The battery pack also has a connector cable with a connector plug at its distal end mateably receivable in the tool socket so that the battery pack can be disposed remotely from the tool. The battery pack can be mounted on tools with which it does not mate by use of an adapter having a plug portion mateably receivable in the tool socket, and an adapter socket mateably receiving the battery pack plug portion. Multiple battery packs may be interconnected on a wearable carrier and connected to the tool by a cable with a plug connector.

摘要： A portable battery jump start unit includes a portable, plastic, clamshell-type housing including a box-like open-top base and a box-like, open-bottom cover hingedly connected together for movement between open and closed conditions. A lead-acid battery is disposed in the housing, along with a state-of-charge monitoring circuit connected to the battery terminals and including a visible indicator viewable through an aperture in the housing. Cables are connected to the battery terminals and respectively extend through openings formed by cooperating notches in the mating edges of the base and cover, the cables respectively having clamp connectors at their distal ends which can be clamped onto posts projecting laterally outwardly from the sides of the base. A charger jack in the base is connected to the battery terminals for receiving a charger connector.

摘要： A lead-acid battery pack has an electronically-controlled power switch connected in series with the battery. A voltage monitor/controller is connected in series with a normally-open ON/OFF switch across the battery, the controller controlling a ramped pulse width modulator which provides a switch control signal to the power switch. The controller is program controlled so that, a fraction of a second after the ON/OFF switch is closed, the modulator will provide a constant DC level control signal to the power switch to hold it closed. If the battery voltage drops below a first level for several seconds, the modulator will produce a PWM switch control signal of gradually decreasing pulse width and duty cycle until the power switch is permanently open. This gradual decrease of power delivered from the battery will occur immediately upon the battery voltage dropping below a second level lower than the first level.
摘要翻译： 铅酸电池组具有与电池串联连接的电子控制电源开关。 电压监视器/控制器与电池两端的常开ON / OFF开关串联，控制器控制斜坡脉宽调制器，该调制器向电源开关提供开关控制信号。 控制器被编程控制，使得在ON / OFF开关闭合之后的一秒钟的时间内，调制器将向电源开关提供恒定的DC电平控制信号以使其闭合。 如果电池电压下降到低于第一电平几秒钟，调制器将产生逐渐减小脉冲宽度和占空比的PWM开关控制信号，直到电源开关永久打开。 当电池电压下降到低于第一电平的第二电平时，电池输送功率的逐渐降低将立即发生。
