Abstract: This application discloses an apparatus and method for generating and radiating energy at specific radio frequency wavelengths known to adversely affect the nervous systems of small insects such as flies, gnats, cockroaches, termites and the like wherein each is affected by a different frequency or range of frequencies; the apparatus containing a power supply, a voltage selector circuit for generating sequences of specific voltages, a modulator circuit to amplitude modulate each specific voltage about its center level, a multiple frequency generator to convert each modulated voltage into a modulated frequency of both fundamental and harmonic content, a radio frequency transmitter circuit, and a random interval timer circuit to energize and de-energize the radio frequency transmitter circuit in such a manner as to prevent the pest from acquiring an immunity to the radiated energy.
Abstract: A runout and braking device, particularly for medium steel rolled sections, includes a run-in roller table and a braking device arranged laterally offset and parallel to the run-in roller table, wherein the run-in roller table and the braking device form a runout and braking system. The runout and braking device of the above-described type includes a braking device with a rigidly arranged braking trough with a bottom which is outwardly inclined relative to the horizontal direction. The run-in roller table includes a lifting bottom forming a plane, wherein conveying rollers mounted below the lifting bottom protrude above the plane of the lifting bottom. Pivoting devices are provided for pivoting the run-in roller table together with the lifting bottom and the conveying rollers arranged below the lifting bottom about a laterally offset pivoting point into an inclined position toward the braking trough.

Abstract: An apparatus for applying surgical fasteners is disclosed which includes a first lockout assembly configured to prevent premature ejection of fasteners during shipment and handling and a second lockout mechanism preventing reactuation of the apparatus after it has once been actuated. The second lockout mechanism includes a hook portion which engages a slot in the floor of the carrier channel.
Abstract: A device for microanastomosis of blood vessels has a housing (1) provided with a gripper (3) for grasping and crimping staples (4, 5), housing (1) enclosing a mechanism for crimping staples (4, 5) by actuating the gripper (3). This mechanism has a control member (16) which is accessible from outside the housing (1), a staple magazine (33) and a mechanism for transferring a staple (4, 5) from the magazine to a position between the jaws of the gripper (3) which is likewise controlled by a member (9) accessible from outside the housing (1).
Abstract: A tool for driving a nail or other fastener is actuated by a caseless propellant charge formed of combustible material that is transported into a combustion chamber on a strip. The propellant charge is ignited by striking a sensitizer portion of the charge at an oblique angle. The ignition member intermixes the sensitizer material with an oxidizer layer of the surface of the propellant charge, resulting in combustion of the charge. When ignited, the propellant charge is compressingly interposed between an orifice plate and a movable portion of the combustion chamber. The orifice plate includes a pedestal with an annular compression surface that separates the surface of the ignition area from the remaining surfaces of the charge, insuring that ignition gases are forced through the charge. An annular C-shaped ring is interposed between the orifice plate and the movable portion of the combustion chamber.
Abstract: An endless conveyor for ring spinning machines comprises bobbin pegs (13) for receiving full and/or empty bobbins which seen in the conveying direction of the endless conveyor (17) must assume an exact position on the endless conveyor (17) in order in a predetermined bobbin change position to come into alignment with a spinning point (11) or other bobbin support arrangement and thus ensure a perfect bobbin transfer from or to the bobbin peg (13). Each bobbin peg (13) is mounted on the endless conveyor (17) adjustably in the conveying direction via a driver (19).
Abstract: A textile machine has a bank of spindles each provided with a flyer having a presser finger and a fork having a plurality of elongated teeth thereon for simultaneously removing full bobbins from the spindles and for supplying empty bobbins to the spindles. A safety device is provided for moving the presser fingers out of the paths of the empty bobbins as the empty bobbins are inserted into the flyers, comprising deformable elements extending longitudinally of the teeth of the fork. The presser fingers have members thereon so positioned as to be engaged by the deformable elements and to swing the presser fingers out of the paths of the empty bobbins when the empty bobbins are inserted into the flyers by movement of the fork in one direction.
Abstract: The grippers are mounted on a doffer bar so as to disengage from both the top and bottom of the bar should a mis-alignment occur relative to a bobbin tube. The removal or separation of a gripper from the bar causes a pneumatic or electrical signal to be generated which can be used to indicate the individual disturbance location. A light may also be provided at each gripper station in order to indicate a position of a disturbance.

Abstract: A drag device for a spinning reel, which is provided with first and second drag mechanisms for applying a rotational resistance to a spool shaft carrying a spool on which a fishing line is wound and with adjusting members of the drag mechanisms which are independently operable. A support cylinder is provided at a the reel body of the spinning reel and rotatably supports the adjusting member of the second drag mechanism. The support cylinder is provided with a regulation mechanism for regulating an adjusting operation range of the adjusting member of the second drag mechanism and an engaging recess for indicating substantially the center of the adjusting operation range. The adjusting member at the second drag mechanism is provided with an engaging member slidable radially of the support cylinder and engageable with the engaging recess and a spring member for biasing the engaging member in the direction of engaging with the engaging recess.
Abstract: The machine comprises a series of rotatable spindles (3), each of these being associated with respectively one cap-shaped thread guide member (7) rotatable about the spindle axis. A first drive belt (5) serves for turning the spindles (3). A second belt (12) is in contact with whorls (11) on the thread guide members (7). A device exerting contact pressure (13, 14, 15) urges the second belt (12) during operation against the whorls (11) with an adjustable force so that the belt (12) exerts, by means of friction, a small braking force on the whorls (11) running faster than the belt (12). The contact pressure device (13, 14, 15) can be switched over in order to press the second belt (12) against the whorls (11) with a substantially greater force. Upon shutoff of the spinning machine, the contact pressure device (13, 14, 15) is switched over so that the decelerating second belt (12) exerts a substantially greater friction force on whorls (11) and rapidly brakes the thread guide members (7) concomitantly.
