Abstract: A bottle orienting apparatus for orienting at high speed a train of successively advancing, randomly oriented, bottles having an open end and a closed end into a train of bottles having a uniform orientation, is disclosed. The apparatus comprises a guide system for advancing the bottles in the randomly oriented train, a discriminating system for inverting each of the bottles of open-end leading disposition in the train to an open-end trailing disposition and for passing through the discriminating system without inversion each of the open-end trailing bottles in the train, and a take-off system for removing uniformly oriented bottles from the discriminating system.

Abstract: A control for controlling load on a tire undergoing testing while rotating in a loaded condition against a test road wheel. As the tire temperature increases during the warm up period of the tire and inflation pressure and load consequently also increase, the control will automatically decrease the load applied to the tire to maintain a preset load on the tire. During equilibrium temperature and pressure conditions of the tire, the control will effectuate decreases in load only and will not permit the tire load applicator to oscillate the load about the reset load point. The load applicator is maintained in an inactive condition by the control means except when a load decrease is necessary. During equilibrium temperature and load conditions on the tire, a relatively fast increase in temperature and a correspondingly fast load increase indicating incipient failure of the tire can be detected by the control.

Abstract: A run-flat insert structure for a pneumatic tire is disclosed in which the insert structure comprises a homogeneous elastomeric material and is fully enclosed and pneumatically inflated. The insert structure is mounted within the cavity formed by the pneumatic tire and the wheel rim upon which the tire is mounted. The insert structure is shaped and spaced from the interior walls of the tire such that contact between the insert structure and the interior tire walls is minimized during rated load carrying and inflation conditions of the tire. The volume of the insert structure is less than 50% of the volume of the cavity formed by the tire and the wheel rim to thereby assist in avoiding undesirable contact between the insert structure and the tire. During the deflated condition of the tire, the insert structure supports the tire and its load at a deflection that prevents excessively rapid deterioration of the tire while running in the deflated, run-flat condition.

Abstract: A bottle conveying and cleaning apparatus for handling a succession of bottles at high speed. The apparatus comprises a lower portion of a vertical first rotary conveyor which receives the bottles in open-end trailing disposition, reorienting means which changes the disposition of each bottle to open-end radially outward during its conveyance by the first rotary conveyor, a linear conveyor which grasps each bottle at the bottom of the first rotary conveyor while its open end is downward and maintains each bottle in open-end downward orientation while conveying it past cleaning means associated with the linear conveyor, and means for inverting each bottle, removing it from the linear conveyor and placing it on an output conveyor with the open end up.

Abstract: The game includes at least one envelope, each envelope having a first face and a second face. Each face is provided with at least one window therein. Associated with at least one window on each face are sets of indicia. A slide is movably retained within each envelope and has printed thereon different sets of indicia. A player positions a marker on the slide which appears in a window in the first face of one envelope adjacent one of the indicia associated with the window which corresponds to a particular action or move in the game being played. This reveals in a window in the first face instructions to position a marker on the slide adjacent a particular indicium on the second face of the one envelope or a second envelope called for in the instruction. When the marker is so positioned the succeeding action is displayed in a window on the second face. In addition, instructions appear as to the position into which the marker on the first face is to be moved and the game continues accordingly.

Abstract: A single-screw extruder and process for mixing viscous materials, for example, rubber mixtures and thermoplastic materials. The process and apparatus includes inserting a plurality of obstacles in the flow path of the material stream in the interior of the extruder cylinder. The obstacles are in the form of a number of series of studs protruding into the cylinder and accommodated by respective gaps or openings in the threads of the screw. The depth of penetration as well as the number of studs can be varied and adjusted by automatic means. The penetrating portion of the studs can be of different shapes according to the requirements for a thorough and turbulent deflection and mixing of the material stream.

Abstract: A tile stacking machine wherein each tile is tilted while being conveyed at high speed and supported by its lower edge. The tiles are then transferred to a set of speed reducing belts to travel on edge. In most instances they are then transferred to at least one further set of speed reducing belts so as to crowd the tiles into a stack. One of the features of tilting the tiles while being conveyed edgeways, is that tilting is achieved by slowing the leading edge as it is lifted, thereby reducing tile speed even before it enters the speed reducing belts.
