Abstract: The present invention relates to the manipulation of paper roll heads by means of a multi-axis robot (8). When the heads are fetched by means of the robot (8) from multiple piles (1 - 7), valid information on the position or height of the piles (1 - 7) is not known by the robot (8) after the piles are replenished. According to the invention, when the operation of the robot (8) is halted for the duration of, e.g., the replenishment of the head piles (1 - 7), the parameter data for all piles are set unknown. As the system operation is restarted, the robot (8) performs a slow-speed approach toward an uncalibrated pile, measures the pile data, that is, calibrates the pile height and position, and thus can perform the next pile approach through a normal fetch cycle on the basis of the measured data. <IMAGE>

Abstract: The invention relates to a drive pulley for a continuously variable transmission in which the driven pulley is driven by a belt of trapezial section connecting to said drive pulley. 
<??>The drive pulley comprises two coaxial flanges (1, 2) whose flanks (3, 4) confront each other to form a "V" groove (5) in which the belt (6) runs, the non-moving flange (1) is fixed to the end of a hub (7) anchored to a drive shaft (9) and the moving flange (2) can slide axially along said hub (7). A reaction cap (23) is made fast to the hub (7) and hence to the drive shaft (9). As the drive shaft (9) of the pulley rotates, a number of centrifugal weights (30) are subjected to centrifugal forces which cause the moving flange (2) to move towards the non-moving flange (1), and a return spring (19) is provided in order to exert a force in opposition to the approach of the two flanges (1, 2). The moving flange (2) is coupled in rotation to the drive shaft (9) by means of a rubber membrane (35) which connects it to the reaction cap (23) and has a part of revolution which in cross-section is arched. 
<??>The hysteresis generally encountered with this kind of pulley is greatly reduced by this membrane.

Abstract: The invention relates to a method for picking up sheets of paper,  cardboard or similar,  especially porous material, one at a time from a pile of sheets for onward transfer, using a gripping apparatus fitted with gripping means and a sheet support disk, and a gripping apparatus for effecting the method.   According to the invention when the gripping apparatus is brought to the pile of sheets it achieves the following steps: a.  the pile of sheets is pressed on its top in the central region thereof, b.  the gripping means is moved and presses the top of the pile on both sides of said central region, c.  the top sheet on the pile is distorted preferably from both sides of the central region of the pile by making use of movement of the gripping means towards the central region of the pile so that said top sheet bends partly clear from the sheet under it, d.  the top sheet of the pile is raised up by the gripping means to the level of the support disk at the same time as pressure is still being applied to the central region of the pile, e.   the pressure on the central region of the pile is ceased  and  simultaneously  the  sheet  is  flattened  out against  the  support  disk  by moving  the  gripping means outwards from the central region of the sheet.

Granted: 1999-11-16
Abstract: A feed material is melted by a focussed laser beam in a partially confined interaction volume, and ejected from the interaction volume in a direction different from the axis of the laser beam. The feed material, preferably in the form of a finely divided powder fluidized by a gas stream, is fed to the interaction volume in a direction transverse to the axis of the laser beam. Confinement of the molten feed material is preferably attained using balanced gas pressures that do not permit the molten feed material to flow in the direction parallel to the laser beam. The energy density of the laser beam is preferably sufficiently high to form a plasma within the interaction volume from gas and vaporized feed material atoms, so that the feed material is introduced into the plasma.

Title: Restraining devices
Inventor: WARD SUSAN P
IPC: B62B9/24
Filed: 1990-02-20
Granted: 1995-07-04
Abstract: Problems encountered  in adapting child  restraint devices of the kind used to retain a child in the seat of a shopping cart, "stroller", dining chair, or like device, for use in different circumstances and with children of different sizes, are overcome by a restraining device which comprises a pair of straps, each having a releasable fastener at each end portion.   The cooperating parts of the fastener are spaced apart lengthways so that when they are fastened the end portion will form a loop. In use, the straps are placed over a child's shoulders and crossed over each other both front and rear.          The ends of the straps are attached to a belt secured around the child by looping the end portions around the belt and fastening the releasable fasteners.   The restraining device conveniently restrains the child in the seat, the shoulder straps preventing it from wriggling upwards out of the waist belt.  Because the straps are releasably attached to the belt, they can be used independently.   For example,  they can be attached to a belt which is already attached to the shopping-cart,  "stroller"  or  the  like  to convert  it  into a  more effective restraining device.  Alternatively, the straps can be fastened directly to the frame of the device.

Abstract: A gas turbine engine rotor assembly has an inertial damper loosely surrounding a portion of the main rotor shaft. The damper is axially compressed between facing abutment surfaces provided on a nut and bevel gear. The damper has two axially spaced rows of circumferentially spaced slots, with the interrupting web portions of each row being circumferentially staggered with respect to one another. The damper is configured and dimensioned so that the axial force exerted by the damper on the nut and bevel gear, the polar moment of inertia of the damper, and the coefficient of friction between the damper end faces and the abutment surfaces, cooperate to effectively damp the excitation of the fifth-stage blades in response to application of a source of vibrations at a particular frequency to the bevel gear.
