Abstract: A shield is placed on a patient's body over a secondary organ adjacent a target organ. The shield is partially transparent to x-ray radiation. A CT scan of the target organ is conducted according to conventional protocols and technical parameters. No artifacts are formed in the diagnostic portion of the CT image and there is no degradation of the diagnostic portion of the CT image. A reduction of between about 40% and about 60% in the radiation dose of the secondary organ as compared to the same CT scan made without the shield is achieved.

Abstract: An interposer assembly includes an insulating plate with passages extending through the thickness of the plate and projections extending into the passages. Metal contacts are confined in the passages by the projections. The contacts include noses that project outwardly from the plate for engagement with contact pads on overlying and underlying circuit members.

Abstract: A humane, pain-free method of animal training includes interrupting the animal's vision to deliver a training stimulus. A lens having an electro-optic shutter is placed within the animal's field of vision. The shutter is open and does not obstruct or interrupt the animal's vision while the animal exhibits desirable behavior. The shutter is closed and interrupts the animal's vision to deliver a training stimulus as needed. The closed shutter is re-opened to remove the training stimulus and continue training.

Abstract: An interposer assembly includes an insulating plate with passages extending through the thickness of the plate and projections extending into the passages. Metal contacts are loosely confined in the passages by the projections. The contacts include noses that project outwardly from the plate for engagement with contact pads on overlying and underlying circuit members.

Abstract: An apparatus for cutting fabric includes at least one fabric wind-off device (1, 1′) for one fabric bolt (7), a conveyor belt (5) for conveying the unwound fabric, and a cutting device (3) which cuts a piece of fabric to a given shape from the length of fabric deposited on the conveyor belt (5). Said conveyor belt (5) extends without interruption from at least that point where the fabric is deposited by the wind-off device (1, 1′) to the working area of the said cutting device (3). The wind-off device (1, 1′) places the length of fabric directly onto the conveyor belt (5) or onto one of more lengths of fabric already deposited on the said conveyor belt. An apparatus control automatically feeds the unwound fabric to the cutting device and directs the cutting of the unwound fabric by the cutting device.

Abstract: A double sided edge clip terminal for forming soldered connections with opposed contact pads on the edge of a substrate includes a pair of solder contacts each having spaced metal arms and cold extruded solder masses in the interior of the contacts between the arms. Openings are formed in the contacts between the arms to prevent wicking of molten solder along the terminal and away from the contact pads. The terminals are manufactured by extruding the solder masses through the openings and into the space between the arms and beyond the arms, without solder waste.

Abstract: An image positioning device includes surface elements having front and back sides and images on the front and/or the back sides. An end of a first surface element and a front side of a second surface element are turnably coupled along a first axis of rotation and an end of the second surface element and a front side of a third surface element are turnably coupled along a second axis of rotation. The first and second rotational axes are approximately parallel with one another. Successive flipping of the surface elements animates the images.

Abstract: An improved ampule breaker that is snapped over an ampule tip and held in a desired location with a collar flush against the top of an ampule body, a stiff ring fulcrum support surrounding the score line in the neck of an ampule and the ampule tip closely surrounded by a plurality of locating ribs. The ampule tip is broken away from the ampule body by rotating the breaker to one side of the ampule so that the tip is rotated about the ring fulcrum and is broken away from the ampule body at the score line with a smooth break and without the formation of shards.

Abstract: An interposer assembly includes an insulating plate with passages extending through the thickness of the plate and metal contacts loosely confined in the passages. The contacts include noses that project outwardly from the plate for engagement with contact pads on overlying and underlying circuit members.

Abstract: A device for stirring bone cement includes a bone cement cartridge having a piston at one end of the cartridge and an elongate stirrer extending through the piston and along the cartridge. Bone cement powder and liquid are mixed in the cartridge by relative rotation between the cartridge and stirrer. The mixed bone cement is extruded from the cartridge by moving the piston along the cartridge and the stirrer.

Abstract: An interposer assembly includes an insulating plate with passages extending through the thickness of the plate and metal contacts loosely confined in the passages. The contacts include noses that project outwardly from the plate for engagement with contact pads on overlying and underlying circuit members.

Abstract: A cutting tool has a tool body and cutters metallurgically bonded to the tool body. The cutters are formed from laser to the tool body, with each cutter having a cutting edge formed thereon.

Abstract: An accumulator-type blow molding machine includes hydraulic cylinders for closing mold parts on platens and a control system for valves flowing hydraulic fluid to the cylinders. The control system calculates the desired position of one platen from the measured position of the other platen and generates work output signals accordingly.

Abstract: A bone cement mixer having a cartridge housing for receiving an open bone cement cartridge filled with bone cement powder with a stirrer in the cartridge, and a cover which is fitted over the housing to define a vacuum chamber. The chamber is evacuated and monomer liquid is flowed into the bone cement powder in the cartridge in a stream that penetrates the bone cement powder and distributes monomer liquid essentially uniformly along the height of the bone cement powder. The powder and liquid are then mechanically mixed to form bone cement.

Abstract: A bone plate includes a pair of mounting portions with bridges extending between the mounting portions. Each bridge includes at least one spring member and a compression member, arranged in series.

Abstract: Wooden log walls are constructed from full or siding logs stacked one above the other. The logs engage each other at connecting portions including an interior loose tongue and groove joint and downwardly curved cylindrical load supporting surfaces extending to the outer sides of the logs.

Abstract: A take-out mechanism for removing sets of blow molded bottles from a blow mold includes a rotary turret, a take-away conveyor and a drive for moving the turret between the blow mold and the take-away conveyor. The turret has a number of sides with a plurality of vacuum plugs extending from each side. The drive moves the turret toward the mold to extend a set of plugs on one side of the turret into mold cavities and vacuum-capture bottles molded in the cavities. After opening of the mold, the turret is lowered and rotated 90.degree. to position the vacuum-held bottles at the infeed end of the take-away conveyor. Rotation of the turret positions a second set of plugs facing a second mold moved to the take-out position. Subsequent rapid retraction of the turret moves the set of removed bottles into the take-away conveyor and powers the conveyor to receive the bottles while maintaining orientation between individual bottles.

Abstract: The disclosure relates to a stacking machine which cuts a multiply rope into bundles, clamps the lead ends of the bundles against a conveyor which moves the bundles to stacking stations where the bundles are collected in stacks. Completed stacks are transferred to a takeaway conveyor.

Abstract: An accumulator-type blow molding machine includes hydraulic cylinders for closing mold parts on platens and control systems for valves flowing hydraulic fluid to the cylinders. The control systems generate work output signals for the valves according to the operational parameters of the valves, the hydraulic systems and the bearings supporting the platens.
