Abstract: Magnets attach a resilient material protector to the sides of a vehicle. The protector also includes a hook that fits between the vehicle door and the door post to prevent the protector from being removed from the vehicle when the door is locked. The protector has two portions that fold over each other such that the magnets on the respective portions align with each other and secure the portions together in a stowed position. The hook embeds in one portion of the protector and can extend between the vehicle door and its post to secure the protector to the vehicle. A recess opposite the hook in the other portion of the protector receives the hook's free end. The magnets have soft material on their outside to prevent the magnets from scratching the vehicle.

Abstract: The handling apparatus includes two spaced apart lower arms pivoting on a base, and two spaced apart upper arms pivoting on an elbow bearing on the lower arms. The lower arm is driven by a ball-screw arrangement in which a threaded drive, mounted on the base of the apparatus is connected to a ball screw attached to a strut between the ball screw and the lower arm. Moving the ball screw along the threaded drive member pivots the lower arm upward. Another ball screw arrangement is mounted on the lower arm and is attached to the lower end of the upper arm by means of cables that extend along a rear curved surface of the upper arm to allow for more travel of the upper arm. Various attachment can be mounted on the upper arm including hangers for propellers and rudders and a gripper unit for supporting propeller shafts. When handling propellers and rudders, a single material handling unit is used, and the propeller or rudder is hung between the spaced apart arms.

Abstract: A tool for countersinking nails into a workpiece has a base member, which is formed of resilient material, and has a generally flat bottom section resting on the workpiece. A metal guide is mounted in the base member. The guide has a central opening for receiving a nail in its bottom. A rigid cap member on the base above the guide has an aperture through it, and a nail set extends partially upward out of the aperture in the cap and extends into the opening in the guide above the nail for transmitting impact from a hammer on the nail. The bottom of the guide member is recessed from the bottom surface of the base so that the metal will not contact the workpiece. The cap has a greater diameter than the guide so that if the cap is struck when the bottom or the nail set is below the top of the workpiece, an impact on the cap is not transmitted to the guide but will be absorbed in the resilient material of the base. A nail starting section integral with the base member extends laterally outward.

Abstract: A cassette type cleaning device for a video tape recorder is disclosed in which a cleaning tape is carried on a pair of reels inside the cassette. The cleaning cassette may be inserted into a recorder and the cleaning tape advanced in moving the contact with the recorder heads and tape guides in the manner of a conventional video tape cassette. The cleaning tape has a non-abrasive surface contacting the recorder and is preferably formed from a synthetic suede material having a thickness of no more than about 0.4 mm, with a bristled surface on the side of the tape contacting the recorder heads. An aperture is provided in the side of the cassette housing in alignment with the tape wound about one reel, allowing cleaning fluid to be dispensed through the aperture onto the wound tape to produce an alternating wet and dry pattern, without exposing the tape by opening the cassette access door.

Abstract: A plurality of carriers for integrated circuit devices are each uniquely coded so as to be recognizable by an automatic decoding apparatus. The devices are tested and the test results accurately correlated with the appropriate devices by recording the test results for each device, reading the identification code for each carrier in the same sequence in which the devices are tested, and then correlating the test results with the device identifications. A prior art requirement of maintaining the carriers in the order in which they were tested is eliminated once the carriers have been thus identified. In a preferred embodiment the carrier body is provided with an array of perforations, the transmission of light through each perforation being blocked by a breakable membrane. Each carrier is coded by breaking a selected combination of its membranes to establish a unique binary identification code for each carrier.

Abstract: A carrier for a leadless integrated circuit chip has a cavity into which a chip is laterally inserted through an opening in a side wall of the carrier. A spring arm formed integrally with the carrier flexes backward in a recess to permit insertion of the chip, which has a plurality of electrical contact pads on its upper surface, and then bears against the chip under an internal spring bias to retain it within the cavity. Tabs at the upper corners of the cavity are positioned over the corners of the chip which are free of electrical contact pads, thereby preventing the chip from escaping while exposing the pads for both single and dual pin probing. The external configuration of the carrier conforms to industry standards so that the chip can be fully processed and tested without removing it from the carrier.
