The invention relates to an eyeglass frame having a portion of the frame removably coupled to the body of the frame to permit the removal and replacement of the lenses in the frame. The frame includes a shoulder member that serves as a retainer plate and includes a leg portion and a recess located between the leg and a rear portion of the frame. A mechanism for disengaging the recess member can be accessed through the recess and pull of the leg portion to release the retaining member so that lenses can be removed and inserted.

A tool changer including male and female flanges for connecting end effectors to robot arms. A male flange having a tapered projection is inserted into a tapered opening in a female flange having a rod coaxial with the diameter of the tapered opening. A rotatable locking stud is aligned within an opening in the male projection and includes a slot having locking grooves at its lower end. The stud is rotated through an angle causing the male and female flanges to be drawn together until the cooperating tapers are seated together. A spring retains the flanges in the locked position. A cooperating pin and pin receiving socket respectively provided on the male and female flanges at locations displaced from the male and female tapers are utilized to assure proper orientation between flanges and to prevent rotation of the flanges. Electrical terminals on the male connecting flange engage cooperating conductive terminals on the female flange, providing an electrical path between electrical sources and load utilization devices on the end effectors. Pneumatic couplings are also provided between the male and female flanges. A plurality of removable flange identifying pins are arranged along the circumferential wall of the male flange for electrical engagement with cooperating sensors provided in each tool holder of a tool crib for identifying the type of end effector being stored. A single operator arm is provided in the tool crib for simultaneously moving the operating arms of all of the tools in the tool crib respectively to the engaged and disengaged positions.

An ammunition magazine is used with a reciprocally-cycled weapon for delinking and firing cartridges in close-end linked ammunition belts. The magazine includes a housing with an ammunition indexing mechanism fixed to one side of the housing. A magazine feed box is disposed above the ammunition indexing mechanism. The magazine feed box includes a movable follower having an upper and a lower position and cam pins that engage cam slots in the magazine feed box. The movable follower is configured to receive a cartridge from the weapon.

A system and method are disclosed for automatically limiting the drainage of a bodily fluid such as cerebrospinal fluid (CSF) from a patient into a collection chamber. The collection chamber includes a vent having an hydrophobic filter for the passage of air to facilitate the movement of CSF yet to maintain a closed system. The system includes a buoyant float hingedly connected with the top of the collection chamber in one embodiment. When fluid rises in the collection chamber to a predetermined volume, buoyant force raises the float and causes a seal plug mounted on top of the float to seal one of an inflow port or a vent port. The float is limited to pivoting movement in one plane and to a certain angle within that plane. The system and method avoid overdrainage of CSF from the patient and overfilling of the collection chamber.

A reciprocally-cycled, externally-powered weapon may include a rotative driver connected via a crank and connecting rod to the operating group of the weapon. The connecting rod may be connected to a pinion that meshes with a translating rack and a stationary rack. The translating rack may be connected to the operating group, and the stationary rack may be fixed to the receiver of the weapon. The energy needed to fire the weapon may be supplied by an energy generator. The minimum amount of energy supplied by the energy generator may be independent of the speed of translation of the operating group and may be sufficient to reliably result in cartridge ignition, thereby providing an infinitely adjustable firing rate.

An automatically-reloadable, remotely-operated weapon system may include an operator station located distant from a weapon station. The weapon station may include an externally-powered firearm, a firearm mover for adjusting an azimuth and an angle of inclination of the firearm, and an ammunition storage and transport system for automatically moving ammunition to and from the firearm. From the operator station, a user may remotely control all aspects of firearm operation and ammunition reloading.
摘要:
A method for the startup of a solar power three-phase inverter in which a waiting period is increased between successive attempts to start the inverter. This method allows the inverter to start up in a reasonable amount of time while avoiding excessive cycling during prolonged periods of low light.
摘要:
A batteryless inverter allows for a positive or a negative lead from a photovoltaic array to be attached to a grounding terminal of the inverter. Internally a ground fault voltage is rectified and processed to produce a signal that will shut down the inverter. This signal will be the same whether the ground fault voltage is positive, negative, or AC.
