    摘要： A stepping motor circuit in which the electrical damping period for locking the rotor is automatically inversely variable according to the speed of operation. Three monostable relaxation devices provide required timing for effective stepper motor drive. A differentiating circuit resets either one or two of these devices to decrease the period of damping at high stepping rates. Typically, for high stepping rates, the motor supply voltage is increased to rapidly accelerate the rotor and Zener semiconductor breakdown is used to subsequently dissipate energy from the motor coils.

    摘要： A junction box connector assembly formed of a connector junction housing member and an adjustable locking device for locating the housing member on a side wall raceway. The connector junction housing member can be locked in position along the raceway or loosened for movement therealong. A plurality of sets of electrical contacts are positioned in the connector junction housing member, each of the sets being interconnected by a bussing member. A plurality of electrical connector members mates with the connector junction housing member, each connector member having a plurality of electrical contacts for mating with one of the contacts of each set of the contacts positioned in the housing member. The contacts are integrally formed with the bussing member and one or more of the contacts can be easily removed therefrom so that an associated electrical circuit can be disconnected from one or more of the connectors coupled to the junction box assembly. Locking means are provided for simultaneously securing a plurality of electrical connector members to the connector junction housing member. The main cables are positioned in the raceway and are connected by means of electrical connector members to the junction housing member. The main cables have sufficient slack so that the connector junction housing member can be moved along the raceway without disconnecting the connector members securing the main cable to the junction housing member.

    摘要： A spindle for rotatably supporting a reel having both positive and frictional engagement between the spindle and the reel. The positive engagement is made at one end of the spindle, as by means of plural pins which engage plural recesses in the reel. The frictional engagement is made at the other end of the spindle and is provided by a radially expansible elastomer which is expanded by a locking arm. This dual engagement advantageously holds two-piece reels together as well as to the spindle.
