Abstract: A garden umbrella of the generally large size having a ribholder runner notch adapted for movement along a hollow umbrella pole for operating the canopy ribs to open and close the umbrella canopy. A pulley wheel is mounted in the umbrella pole below its top portion, with one end of a pulley cord being attached to the ribholder runner notch while the other end of the pulley cord extends down through the hollow pole where it connects to a ballast weight. The ballast weight is adapted to travel vertically in the pole in synchronism with movement of the runner notch. The weight of the ballast weight and its pulley arrangement is selected to provide a uniform ballast force and a constant control which facilitates the opening and closing of the umbrella. A second pulley cord can be attached at one end to the runner notch while such cord extends around a second pulley wheel to a handle attached at its other end.

Abstract: A garden umbrella employing an upper canopy extending from the top of the umbrella pole to the middle of long canopy ribs, and a lower outer canopy extending in a ring around the outer part of the umbrella and having long sleeves sewn across the canopy in a radial pattern for receiving a canopy rib in each sleeve. The canopy ribs are pivotally connected to a runner notch, while the other ends of the canopy ribs are received in the canopy sleeves. Stretcher ribs are pivotally connected between each canopy rib and a top ribholder secured at the top of the umbrella pole. The rib and runner notch configuration, together with the outer canopy, permit very easy opening and closing of the umbrella by movement of the runner notch between its upper, open umbrella position and its lower, closed umbrella position. The lower canopy comprises panels sewn together along the bottom of each rib such that a wind vent space is formed with the upper canopy which extends to the top of each rib.

Abstract: A garden umbrella of the solid wood pole type is designed to accommodate the pulley cord within a specially drilled cord passage located adjacent to a narrow neck slot extending longitudinally between the pulley, located at the top of the pole, and the hand crank near the bottom of the pole. A special drill bit is designed with both (a) narrow neck cutting edges for drilling the narrow neck slot and (b) relatively large main head cutting edges for drilling the cord passage in one simple manufacturing operation. The cord passage is sized to accommodate the pulley cord for up and down movement therein while the narrow neck slot is smaller than the cord thickness, thereby preventing the pulley cord from passing out of the pole through such narrow neck slot.

Abstract: A garden umbrella with a partial top canopy covering the central area of the umbrella and located on the upper side of the canopy ribs, and an underside outer canopy secured to the underside of the canopy ribs and covering at least the outer ring portion of the canopy ribs not covered by such partial top canopy. The underside outer canopy has canopy rib sleeves formed on its top side and adapted for receiving therein the middle and end tip portions of the canopy ribs. The partial top canopy is secured at its outer ends to the upper side of the canopy ribs and the canopy sleeves such that a deep vent is formed between the partial top canopy and the underside outer canopy for venting wind through the space between the two canopies. In one embodiment, the underside outer canopy has a general ring shape with an opening in the center for further venting of wind and updrafts through the center of the umbrella.

Abstract: A segmented seal ring and spring system for steam turbines for minimizing leakage between rotating and stationary components, and preventing damage and wear thereto, including a segmented seal ring, with first springs biased against the seal segments to urge the segments radially outward toward a large clearance position of the seal ring with respect to the turbine shaft. The springs urge the seal segments into the large clearance position at low shaft speeds and small turbine loads, whereas at medium to high flows and high working pressure, working fluid will overcome the spring forces and urge the seal segments into a small clearance position. Special gravity springs are provided in the lower half seal ring segments with the lower end of such springs seated against the turbine casing while the upper spring end is biased against the seal segment to produce an upward force which neutralizes the downward force caused by the weight of the segment.

The main pole has a cylindrical end portion into which a T-nut is securely mounted coaxial with the pole axis. The extension pole has a cylindrical end portion forming an alignment shaft having a diameter that is smaller than the diameter of the main portion of the extension pole, such that an abutment shoulder is formed where the pole end portion meets with the extension pole. A bolt is mounted at the end of the alignment shaft and adapted for being screwed into the T-nut as the main pole and the extension pole are rotated relative to each other. A stabilizer means is mounted at the end portion of the main pole and includes a long tubular alignment sleeve having a length which extends past the end portion of the main pole and receives therein the alignment shaft in a close fitting relationship.

Abstract: Questionnaires are scanned for answers(marks) handmarked thereon by defining areas of interest which can be expanded in an area of interest pixel map. An unmarked questionnaire is initialized by scanning to create a pixel map of an original image area, with any printed objects or text on the page being selected as alignment and reference points, rather than requiring timing marks and special registration marks. Areas of interest are defined answer area locations with their original pixel data stored in an initial database. Questionnaire pages are scanned for new answer images thereon by aligning both the page and the individual answer areas, and comparing the scanned page with the stored, unmarked page pixel map, thereby removing the pre-printed area from the newly scanned area to detect any new answers.

Abstract: A garden umbrella with its underside covered with a lining material that is attached to the ribs. The lining material extends from the runner ribholder, that moves along the umbrella pole, across both the stretcher ribs and the canopy ribs to the ends of the ribs such that the underside of the umbrella is fully covered by the lining. Cloth tabs are sewn onto the lining at selected locations where spring clips secure the cloth tabs and lining to the stretcher ribs and canopy ribs, whereby the lining, the tabs and the clips act to stabilize the ribs from unwanted movement. The use of the lining permits employment of an easily removable umbrella canopy for servicing or replacement with other canopies. Also, the configuration of the lining across the underside of the umbrella is designed to provide a wind deflector which reduces the lift effect of wind against the bottom of the umbrella.

Abstract: A solid wood pole garden umbrella is adapted to permit a hand crank and pulley system to slidably move a ribholder vertically along such wood pole for opening and closing the umbrella. A pulley wheel is mounted in the umbrella pole below its top portion, with one end of a pulley cord attached to the ribholder while the other end of the pulley cord extends through a narrow groove formed longitudinally along the side of the pole down to a lower pole portion where such pulley cord is operatively connected to the hand crank. The pulley cord is contained within the groove in the umbrella pole by a flexible plastic bead or rod which is snugly held or attached to the outer part of the groove to thereby provide a retainer for the pulley cord. The groove and retainer design enables the pulley and crank system to be employed in a solid wooden pole umbrella while maintaining the structural integrity of the pole and avoiding other designs where the pulley cord might interfere with the ribholder operation.

Abstract: A U-shaped belt buckle is pivotally connected to a buckle tongue and key retainer which includes an elongated tongue body terminating at one end in a tongue tip, the other end of the tongue body forming a part of the key retainer. The key retainer includes an elongated hollow housing being open at opposite ends to form a sleeve through which a key may extend in the direction of the tongue tip. Shoulder wall portions at the key receiving end of the hollow housing serve to abut with the head of the key for positioning the key in the housing. The belt has an opening adapted to receive the elongated tongue body and hollow housing, with belt fastener snap buttons positioned on the belt to also function to retain the key by abutting with the head of the key. When the key is needed, the wearer simply opens the snap buttons and removes the key from the key retainer.

Abstract: A pacing catheter having improved torque control properties, including a polymeric tube having an electrically conductive torque member passing through the tube center. The torque member is tapered near the distal end where it is secured to a cup-shaped electrode adapted to fit over the distal end of the polymeric tube. The space between the polymeric tube and the torque member is filled with a polymeric or elastomeric material in fluid form such that a solid, but flexible, polymeric composition is formed which adheres to both the inside of the polymeric tube and the outside of the torque member. The solidified liquid polymeric material allows rotation force applied anywhere along the hollow outer tube to be directly transmitted to the central torque member.

Abstract: A system for correcting the manufacturing errors and variations in the positional alignment and spacing of optical fibers in the scanning head of an automatic digitizing system. A scan head signature is produced by measuring the actual X and Y position for each optical fiber including the variation of each fiber from its nominal X and Y positions. An X correction circuit and a Y correction circuit use the head signature data stored in a signature correction memory to correct the X and Y positions of the stream of scan line data to thereby provide a true video scan of the document data.
