The stepping legs are equipped with pivot limit positions parallel to the vehicle longitudinal axis and to assure chassis stability outside a stepping cycle, a support system is provided with one or two additional rest points.

Abstract: A motor driven by a fluid motion, comprising a rotor with a vane whose surface varies according to the vane position relatively to the fluid flow direction. To create a thrust on the vane when the fluid moves quasi-parallel to the vane longitudinal axis, at least one side-panel is provided on the vane, generally perpendicular to the longitudinal axis thereof.

Abstract: An ultrasonic atomizer for liquids comprises a piezoelectric transducer (16) mechanically coupled to an amplitude transformer (20), an atomizing disk (21) mounted to the free end of the amplitude transformer (20), a housing (22) enclosing at least the amplitude transformer (20) and a cap (30) supporting a sieve-like diaphragm (31). The cap (30) is so mounted to the housing (22) that the diaphragm (31) rests on the atomizing disk (21). The cap (30) consists of two mutually concentric cap parts (32, 33) of which one (32) supports the diaphragm (31) and the second (33) serves to mount the entire cap (30) on the housing (22). A spring (36) is so mounted between the two cap parts (32, 33) that the sieve-like diaphragm (31) is held elastically against the atomizing disk (21) and that the opposing force from the spring (36) thereby is transmitted into the second cap part (33) fixed in the housing.

Abstract: A compound turret for machine tools such as latches or the like having rotating and non-rotating tooling turrets mounted on a single housing. The compound turret includes a primary drive and a secondary drive. The primary drive includes a compound turret indexing unit operable to index the rotating and non-rotating tooling turrets into the turret operating and turret storage positions. The compound turret indexing unit consists of a harmonic drive that enables the operator to incrementally vary the turret operating position. The harmonic drive achieves high reduction ratios in a single stage thus eliminating the cumbersome gear systems usually implemented to achieve the reduction ratios required. The primary drive further includes a non-rotating tool indexing unit. The non-rotating tool indexing unit is operable to index the non-rotating tooling. The non-rotating tool indexing unit consists of a harmonic drive unit similar to the compound turret indexing unit.

Abstract: The invention relates to an inserting and centering device for associated screw-in pipes. Two semi-cylindrical jaws are connected in articulating manner on the cylindrical inside surfaces of which are provided an annular projection having an annular, downward shoulder to rest on the socket edge of the pipes.The jaws further comprise, at their upper end, a conical flare joining the said projection. Each jaw is equipped with one handle. the device further includes a closure mechanism to keep together the jaws when they are in the closed position wherein the jaws enclose with play the pipe socket. One handle of at least one jaw at the same time is designed to be a part of the closure mechanism.

Abstract: A method for controlling substantially equal distribution of particulates from a multi-outlet distributor in a conveying system conveying a supply of particulates to at least a first receiver is disclosed wherein a relationship between the velocity of the moving particles and the internal diameter and the heighth above a cone in the distributor is utilized to control distributor deviation.

Abstract: A cup marking attachment for beverage dispensing machine having a plurality of nozzles for dispensing different flavors or brands of drinks. The attachment comprises a plurality of stamp members containing marking material and indicia mounted adjacent each of the nozzles for identifying the beverage being dispensed by that nozzle. As a drink cup is placed beneath the selected nozzle, the indicia of the stamp member engages the side of the cup and imprints the flavor or brand of the beverage thereon.

Abstract: A process for permanently imaging data on lottery tickets and the like which comprises of steps of; providing an ink receptive, non-shrinking resinous coating on a webbed coupon substrate and heat curing the same, applying to the ink receptive resinous coating, imaging data by an ink jet printer using a sublimable dye, drying the dye, applying an ultraviolet curable resinous coating over the dye, coating the ultraviolet curable resinous coating by ultraviolet light and further heating the substrate between 275.degree. Fahrenheit and 400.degree. Fahrenheit thereby causing the dye to permanently sublime into the ink receptive resinous coating and the ultraviolet curable resinous coating.

Abstract: Apparatus for filtering air laden with dust or other particulate matter including: a filtering area, an air velocity dissipation zone above the filtering area, a lower tube sheet mounted above the dissipation zone and forming a partial boundary therewith, an air plenum mounted above the lower tube sheet, the air plenum including an air inlet for receiving dust laden air, an upper tube sheet forming an upper boundary of the air plenum, the lower tube sheet including a plurality of holes, the upper tube sheet including a plurality of holes vertically aligned with the holes in the lower tube sheet, a plurality of clean air outlet tubes having upper end, main body and lower end portions, the upper end portions being mounted within the holes in the upper tube sheet, the main body portions extending through the holes in the lower tube sheet, the lower end portions extending beneath the lower tube sheet and ending in a horizontal plane at the interface between the dissipation zone and the filtering area, a plurality

Abstract: A mobile shovel excavator having a superstructure rotatable about a vertical axis on an undercarriage wherein the arc circumscribed by the rotating superstructure projects beyond the undercarriage, and a stump jib pivotable on the superstructure about a vertical pivot axis by means of a hydraulic cylinder is provided; an excavator jib is attached to the distal end of the stump jib, and the excavator jib is pivotable about the stump jib; in use, the stump jib may be pivoted so that the outer end thereof is either inside or outside of the arc circumscribed by this superstructure, thus varying the pivot point of the excavator jib, and when the excavator is not in use, both the stump jib and the excavator jib are entirely positioned within the arc circumscribed by the rotatable superstructure.

Abstract: A one-piece collet for use in machine tools, which collet comprises a rear portion which is cold worked to provide a bore of smaller diameter than the bore of the central portion of the collet, which reduced bore is threaded. The cold working of the rear portion produces a transitional area between the different sized bores of the rear and central portions which is characterized by a smooth, uniform grain flow, with unbroken flow lines, resulting in increased tensile strength and longer fatigue life of the collet. The front portion of the collet may also be cold worked to provide a similar transitional area between the central portion of the collet and the reduced bore of the front portion of the collet.
