Abstract: A thin flexible disk of opaque material and at least one flexible disk comprised of a translucent plastic material is provided in a kit. A shooter aims a weapon such as a rifle in the normal fashion with the optical axis of one eye aligned with the rear and front sights on the rifle. While the rifle is being aimed, the other eye, that is, the eye which is not consciously doing any aiming, has the opaque disk applied to the lens of the shooter's glasses. The opaque disk is then moved around until it is aligned with the pupil and on the optical axis of said other eye. A translucent disk is then applied coincidentally with the opaque disk after which the tentatively adhered opaque disk is removed.

Abstract: A movable storage unit control system is provided with: a leading edge safety tape switch for contacting it to bring a driven unit to a stop; a processor for generating move and stop command signals; a plurality of circuits through which test signals are transmitted under control of the processor and which are returned to the processor coincidentally with their transmission through a current sensor if the circuit tests good; a procedure for having the processor address a test signal to a nonexistent circuit to determine if the current sensor has failed and is allowing return of signals when it should not; circuits for setting minimum and maximum speed of the motors that drive the storage units; a circuit for setting the intensity of dynamic braking of the drive motors; and, a watchdog circuit that shuts down the processor upon occurrence of intense temporary electrical noise or software execution errors and is involved in causing the processor to shut down and block all commands to the system if the processor

Abstract: A machine for conditioning a stack of pads, such as sanitary pads, for packaging includes a rotor. Radially extending chambers having closed sides and open front and rear ends are fastened to the rotor. There is a compressor plunger in each chamber. The plungers are carried on guide rods extending from cam follower brackets. A stationary cam plate is mounted perpendicular to the rotational axis of the rotor. The follower rollers are spring biased into contact with the periphery of the cam plate. The chambers are incremented in angular steps starting with a position in which the chamber is stopped momentarily for being loaded with a stack of pads at which time its plunger is retracted. As the loaded chamber increments in two angular steps to an unloading position, the plunger is driven out by the cam to compress the stack. When the chamber rotates from loading position to unloading position, the pads are effectively turned so they are standing on their edges in the unloading position.

Abstract: A cylindrical ink roller rotates as a result of being in tangential line contact with an adjacent roller that is driven rotationally. The roller is suspended for rotation and axial oscillation on bearing cages including bushing for turning and sliding on the shaft. A plurality of springy curved steel wire ribs have corresponding one ends fastened to the bushing and the ribs extend axially for their corresponding opposite ends to fasten to a ring member which fits inside of the roller. The ribs flex or bend slightly to allow the roller to be forced into perfect parallelism with the adjacent roller. The open ribbed roller suspension cages afford free flow of air axially through the roller for cooling it. One or more fans can be installed in the roller. A mechanism for oscillating the roller axially is confined inside of the roller and so designed that cooling air can flow past it.

Abstract: An elastic tie down comprises an elastic tube that carries a slack rope inside thereof. The tube is tightly crimped directly to the rope, so that pulling the rope ends stretches the tube and imparts elastic qualities to the tie down. In a modified embodiment, an annular insert is placed into the ends of the tube, and the rope passes through the insert. The tube and insert are clamped, causing the insert to collapse to grip the rope. The present invention also includes abutments crimped to the rope for cooperating with bushings placed within the tube ends. The bushings are split and have inwardly converging surfaces that terminate in grooves. Tension applied to the rope ends causes the abutments to contact the bushing converging surfaces and force the bushings apart and into a tight grip with the tube and with solid rings surrounding the tube over the respective bushings. The invention further includes split sleeves held in place in the tubing ends with wedges. A passage through the sleeves receives the rope.

Abstract: Oblong articles such as sanitary pads moving in the direction of their length dimension are deposited on article carriers at the lower level of an ascending run of an input closed loop chain conveyor with corresponding one sides of the articles facing up. There are means for pivoting the carriers laterally at the upper level of the run to initiate turning of the articles about the line along which they are being conveyed. They turn 90.degree. by the time they land on the paddles or carriers of an adjacent output conveyor which has a run descending from said upper level to a lower level so the articles which have been turned are also inverted when they complete their descent.

Abstract: A reversible ratchet wrench employing spaced plates which hold the sockets and ratchet mechanism in assembly has an offset handle to provide clearance for the hand of the user. The pawl of the ratchet mechanism is in the head portion of the wrench adjacent the socket and the spring-loaded plunger is supported in the handle portion. The pawl and plunger engage at an oblique angle at a juncture zone between the handle portion and the socket head portion, which juncture zone affords clearance for operative movement of the ratchet and plunger during use.

Abstract: A flattened tubular plastic tube having one pair of edge creases is withdrawn from a vertical axis reel and passed through horizontal axis rollers to impart a pair of intermediate creases. Cooperating rotating and stationary blades cut the plastic tube into short sleeves which are immediately gripped between actuator shoes on a pair of translating chains and a pair of translating frictional belts. The compressively interfaced actuator shoes and belts advance the sleeves to the inlet of a channel defined by laterally spaced apart slide members which have v-grooves into which opposite creased edges are inserted at the inlet whereupon hooks on another chain loop push the sleeves through the channel. The channel width converges so the sleeves open as they are pushed along the channel to be engageable by the head of a passing bottle.

Abstract: A safety floor for a mobile storage system includes one or more flat panels having end brackets that overlie horizontal support surfaces on the system rails. The brackets define longitudinal troughs, in which are mounted leaf springs and safety switches. The leaf springs have lifting pins that extend through holes in the brackets to contact the rail support surfaces and resiliently supported by the panel. The safety switches also have lifter pins that extend through the bracket and that are spaced a predetermined distance above the rail support surfaces. When a person steps on the panel, the panel deflects towards the rail support surface so that a safety switch lifter pin contacts and is actuated by the rail support surface to control the mobile storage system electrical circuitry. The springs are adjustable to accommodate different panel sizes and weights while maintaining the desired distance between the safety switch lifter pins and the rail support surfaces.

Abstract: A mobile storage system includes movable carriages that are stoppable by solenoid operated mechanical safety brakes. The solenoids are controlled by an electrical circuit that includes a safety floor and/or a safety sweep. Actuating the respective safety switches activates the circuit to energize the solenoids for operating the brakes. The safety floor portion of the circuit is designed to energize the brake as long as a safety floor switch is actuated. The safety floor circuit portion contains a timing device that holds the solenoid in the energized condition for at least 3 seconds after deactuation of the actuated safety switch, so that a person walking across the floor does not cause the solenoids to chatter. The safety sweep circuit contains first timing means for deenergizing the solenoid approximately 3 seconds after safety sweep switch actuation. If the actuated switch remains open after approximately 5 minutes, or if a safety sweep switch fails, an audio alarm sounds.

The gas input slot has an elbow connected to it and the elbow is connected to a gas distributor valve which is, in turn, connected to a source of carbon dioxide.

Abstract: A cylindrical mandrel is inserted through the neck of an ammunition case coaxially with the body of the case after which a collet is driven axially onto the neck to form the inside diameter of the neck to the outside diameter of the mandrel without changing the diameter of the case body. In another embodiment an annular bushing of elastomeric material is confined in a space around the neck and the bushing is compressed axially to cause it to bulge radially inwardly so as to apply a force for forming the neck to the mandrel.

Abstract: An insulative panel prevents heat transfer from a molten metal melt. The panel comprises a reinforced refractory slab supported along its edges. An insulation layer is placed on top of the refractory slab, thereby creating a hot zone between the molten metal and the insulation layer and a cold zone in and above the insulation layer. Reinforcing members are placed in the cold zone on top or within the insulation layer vertically above reinforcing rods in the refractory slab. Hangers extending downwardly from the reinforcing members through the insulation layer and refractory slab are joined to the reinforcing rods for supporting the reinforcing rods in the hot zone by the reinforcing or support members in the cold zone.
