Abstract: A self-balancing screw jack that is responsive to small manually applied "upset" loads to move the load in the desired direction. A strain gauge measure the total load and is used to establish a null signal representative of the load at rest. This nulled signal is then continuously compared with the actual load signal. When the actual load signal varies from the preset nulled signal by a predetermined value, the drive motor is actuated to drive the load in the direction of the variance. A non-reversible screw jack is used to support the load in the at rest position.

The nominal tensile strength of the first series of cords per unit width is at least twice the nominal tensile strength of the second series of cord per unit width. The tensile strength of each cord of the first series is at least one and at most ten times the tensile strength of each of cord of the second series. The cords are preferably steel cords.

Abstract: A frame supported conveyor useful in handling baggage includes inclined flights connected to movable link plates to form an endless chain assembly. A drive arrangement located beneath the conveyor engages and moves the endless chain assembly about a closed planar path. The drive arrangement is movably mounted on the frame between an operating position in engagement with the endless chain assembly and a servicing position out of engagement with and movable away from the endless chain assembly.

Abstract: A frame which carries a plurality of circular substrates seated in grooves in planar alignment. The substrates are seated in grooves defined within the circumferential periphery of apertures within the frame. Each groove and aperture have a diameter slightly larger than the substrate, with the groove contacting only a fraction of the rim of the substrate so that the substrate may orbit within the groove as the frame is provided with circular oscillations. This causes rotation of the substrate in the groove, i.e. the rim of the substrate "walks" around the inner circumference of the groove.

Abstract: A device for the disconnectable coupling of a support toggle joint of a gripper to the end of a slave arm of a remote manipulator. The arm and toggle joint each have a case in which are located means for transmitting movements to the gripper. The coupling device comprises at least two latches pivotably mounted on one of the cases and which are able to occupy a coupling position in which they bear against pins fixed to the other case. This couples the toggle joint to the end of the arm and the latches can also occupy a position in which they are disengaged from the pins in order to disconnect the toggle joint. The retractable locking means normally immobilizes the latches with respect to the case supporting them when the latches occupy the coupling position. The invention also provides a disconnection support for the coupling device.

Abstract: There is provided a device and a method for turning flat articles, more particularly letter envelopes, flat bags or the like. The article is first moved out of its direction of conveyance into a curvilinear path, whereafter--without stopping in its original direction of conveyance--it is moved into a curvilinear path in a new direction until finally advancing onwards in its original direction of conveyance.

Abstract: A conveyor device has two endless conveyor belts extending in alignment and advancing in the same direction of (X--X), the adjacent ends of the belts being oriented diagonally with respect to the direction. During transfer between the two belts the products gradually abandon the first belt and pass gradually onto the second belt. This avoids any stumbling of the products, even when these are of narrow and elongate form.

Abstract: Connection means for connecting two components such as conveyor channel sections or guide sections includes an elongate connector. The connector is insertible into laterally-open recesses formed in coupling elements attached to the two components. The laterally-open recesses define an elongate aperture which is slightly longer than the connector so that the connector is received within the aperture with a predetermined amount of axial play. A retaining element prevents axial movement of the connector within the aperture by filling up the space available for said predetermined amount of axial play. The retaining element is an annular disc made of corrosion-resistant, resiliently deformable plastics material. That portion of the resilient element which, in use, is positioned at the mouth of the aperture is, at least partially, of reduced wall thickness when compared with the wall thickness of the remaining part of the retaining element.

Abstract: An apparatus moving a workpiece onto and off of a working station without stopping the conveying line or the conveying carrier.
