  • Patent number: 6948298
    Abstract: A strapping machine has a housing carrying a mount attachable to an overhead balancer line, tensioning and sealing devices in the housing, and an elongated pivotal handle. An inner handle end is formed with an annular inlet passage and a radially throughgoing inlet port opening into the inlet passage. The handle also is formed with axially extending passages extending from the inlet passage to an outer handle end. A pneumatic motor in the outer handle end drives a transmission in the inner end of the handle in turn drives the devices in the housing. An inlet fitting on the housing is connectable to a compressed-air supply line. A conduit has one end communicating with the inlet fitting and an opposite end opening radially inward into the inlet port of the handle. The outer handle end is formed with an outlet opening for venting air from the motor.

  • Patent number: 6866270
    Abstract: A C-section ring fixed on a steel-mill roll and coaxially surrounding its stub has inner and outer axially extending legs defining an axially open cavity. The inner leg is tapered away from the roll and is formed adjacent the free end with a radially outwardly open annular groove. An annular cover part fixed on a stationary support, engaged in the cavity, forming a drain compartment open axially away from the roll, and formed with a radially outwardly open catchment groove radially aligned with a free end of the inner leg is also formed with a passage extending from the catchment groove to the drain compartment. An annular extension on the cover part has an inner surface carrying a seal ring that bears radially inward on the stub. An add-on part on the extension forms with the extension, with the cover part, and with the C-section ring a labyrinth.

  • Patent number: 6635111
    Abstract: Known devices for contactlessly guiding or treating continuous lines of material (1) have one chamber (2). A supply device (3) for a gaseous fluid is connected to said chamber (2), which has a gas-permeable wall (4). The outer surface (5) of said wall (4) is embodied as a guide surface for the line (1). According to the invention, the gas-permeable wall (4) is produced from a porous, metal-containing material with open pores which have an average diameter of less than 500 &mgr;m, preferably less than 100 &mgr;m, especially less than 20 &mgr;m. The porous material used for the guiding surface enables the line (1) to glide on a fluid pad of less than 1 mm. The losses of fluid on the surfaces not covered by the line (1) are very low.

  • Patent number: 6341783
    Abstract: A drill chuck has a body having a front part and a rear part, and formed with a plurality of angled guides opening axially forward at the front part. Respective jaws axially and radially displaceable in the guides are each formed with a row of teeth engaging an internal thread of a one-piece and unsplit tightening ring axially fixed but rotatable about the axis on the chuck-body front part and having an inner diameter greater than an outer diameter of the chuck-body front part. Thus rotation of the tightening ring displaces the jaws in their guides. A one-piece and unsplit snap ring set in the chuck-body rear part bears axially forward on the tightening ring, is formed with an array of outwardly projecting teeth, and has an inner diameter greater than the outer diameter of the chuck-body front part. An adjustment sleeve rotatable about the axis on the body has a front end with a surface bearing directly on the chuck-body front part.

  • Patent number: 6336668
    Abstract: A motor-vehicle door latch has a housing, a pair of levers pivoted at a common axis in the housing, a nut bearing axially on one of the levers and having a screwthread of a predetermined length, and a screw threaded in the nut, having a screwthread of a predetermined length, and having a head bearing axially oppositely on the other of the levers. Thus when the screw is tightened in the nut the two levers are locked together for joint pivoting. An abutment in the housing axially spaced from and confronting the nut is spaced from the nut by a predetermined distance equal to less than each of the predetermined screwthread lengths.

  • Patent number: 6223408
    Abstract: An object, e.g. a piston or a fluid medicament, is inserted into a tubular syringe body centered on a syringe axis and having a pair of ends by an apparatus having a support movable axially forward toward and axially rearward away from the body and a tube extending along a sleeve axis generally parallel to the syringe axis, having a rear end fixed in the support and a front end fittable inside the syringe. A centering sleeve is formed centered on the sleeve axis with a generally frustoconical centering surface engageable with the rear body end surrounding the tube. This sleeve is displaceable axially on the support between a front position with the centering surface projecting axially forward past the tube front end and a rear position with the tube front end projecting axially forward past the centering surface. The support is displaced axially forward toward the body and thereby engages the centering surface coaxially with the body rear end.

  • Patent number: 6151773
    Abstract: An assembly machine has a frame defining at least one work station, a transfer mechanism for feeding a succession of workpieces one at a time through the station, and at least one tool at the station movable between an operative position engageable with the workpiece in the station and a retracted position out of engagement with the workpiece in the station. A push-pull operating element has an outer end connected to the tool and an inner end connected to a cam carried on an output of a drive mounted on the frame for displacing the tool between its positions synchronously with feeding of the workpieces through the station. A pneumatic spring mounted on the frame is braced against the tool and has a compartment pressurizable to urge the tool into the operative position. The back compartment is continuously pressurized with a gas under a generally constant pressure.

  • Patent number: 5758925
    Abstract: A chair has a base, a generally horizontal seat supported on the base, and a generally vertical back supported on the base behind the seat and provided at a predetermined spacing above the seat with a horizontally extending flex joint having formations for permitting free pivoting backward of an upper portion of the back to a predetermined backwardly deflected position and for thereafter resisting further backward deflection. The back comprises a front plate, a cushion carried on the front plate, and a rear plate fixed to the front plate and formed with the flex joint. The formations include a pair of extending flanges extending generally horizontally from the rear plate and a bight interconnecting the two flanges. The flex joint can be unitarily formed with the rear plate. Its flanges are vertically spaced from each other and only touch when the predetermined backwardly deflected position is reached.

  • Patent number: 5188406
    Abstract: A motor-vehicle door latch has a housing, a latch fork pivotal on the housing about a latch-fork axis, engageable in a latched position with a door bolt to retain same and lock the door, and having a latching surface offset from the latch-fork axis, a main latching lever pivotal on the housing adjacent the fork about a main-lever axis substantially parallel to the latch-fork axis, and a secondary latching lever pivotal on the main lever about a secondary-lever axis substantially parallel to the latch-fork axis and having an outer end formed with a surface engaging the latch-fork surface in the latched position. A pair of stops define for the latching levers in the latched position of the latch fork a normal position with the surface in surface contact and an actuated position with the surfaces only in line contact. Thus to open the door the main lever is pivoted from the normal position to the actuated position and thereafter the latching-lever surface is slid off the latch-fork surface.
