Abstract: A method and apparatus are disclosed for applying a strap, which may have identifying indicia printed thereon, about an article, such as a piece of luggage, or other package. The article is placed within an opening defined by a closed loop support frame, and one end of the strapping material is engaged by a carrier pin attached to a chain which travels around the support frame. A loop is formed on the leading end of the tape surrounding the carrier pin, such that when the carrier pin is moved around the closed loop frame, and around the article, the tape is drawn from a supply reel and encircles the article. At the end of its circumferential trip around the article, the movement of the carrier pin is ceased, and the free, leading end of the strap is adhesively secured to a following portion of the strap so as to form a closed loop around the article.

No. 3,863,781, the improvement wherein at least one of the plurality of pivoting doors is mounted on a parallelogram hinge the imaginary axis of which is at least approximately congruent with the axis about which the luggage containers are pivoted, whereby the relative positions of the containers, the conveyors on which the containers are carried through the unloading station, and the pivoting doors remain fixed while the containers are being conveyed through the unloading station.

Abstract: This is concerned with a crusher clearing system using a plurality of hydraulic jacks disposed with relation to the adjustment ring and main frame of the crusher such that the jacks, as a unit, apply a generally vertical thrust directly between the upper main frame flange and the adjustment ring so that uncrushable material may be removed from the crushing cavity in a stalled or jammed crusher. The jacks are arranged in pairs and the jacks are selectively energized so that the adjustment ring will tilt relative the main frame flange.

Abstract: The specification describes two embodiments of a one-piece rear grease seal for an idler roller mounted on a shaft. Both embodiments comprise an annular lip in the shape of a truncated cone, an annular ring integrally connected to the larger end of the annular lip, and an annular web integrally connected to the outer end of the annular ring. In one embodiment, an annular groove is found on the annular ring to receive an axial end of an inner tube mounted concentrically about the shaft; the other embodiment does not have this feature.

Abstract: The specification discloses a two-lobed conveyor ball comprising a hub having a hole therethrough adapted to receive a first axle, second and third axles coaxially mounted on the hub at right angles to the axis of the hole therein and on opposite sides thereof, first and second generally hemispherical lobes rotatably mounted on the second and third axles respectively, and a spacer disc mounted on the hub, extending between the second and third generally hemispherical lobes, and filling the gap therebetween at the outer surface thereof, thereby preventing objects or material being passed over the conveyor ball during use thereof from getting caught between the first and second generally hemispherical lobes.

Abstract: A method and product for compensating ambient temperatures and altering the working time and curing time of a thermosetting resin-hardener compound which is accomplished by selecting and adding a diluent to the resin or hardener blend according to the ambient temperature so that when the resin blend and the hardener blend are intermixed, a heat change is produced which counteracts the effect of the ambient temperature.

Abstract: An adjustable vibratory roller of the type used for compacting soil, asphalt, etc. A rapidly rotating vibration inducing assembly is provided within the compaction roll. The assembly comprises two weights pivotably mounted on supporting channels and a double-ended, fluid operated hydraulic cylinder connected to the weights to pivot them both simultaneously around their respective axes. The cylinder is pivotably mounted on the supporting channels, and one end of its piston rod is directly connected to one of the weights while the other end of its piston rod is connected to the other weight via a connecting link.

Abstract: A wear strip for conveyor chains comprising a flat upper wear member having at least two spaced-apart holes therethrough for the reception of connection means, at least one linear support member joined to the underside of the wear member, and at least two base members joined to the underside of the wear member and having holes therethrough in registry with the holes through the wear member. The whole wear strip is preferably integrally injection molded, and each of the holes in the wear member are preferably countersunk on the upper surface. Two embodiments are disclosed, one in which one linear support member is joined to the wear member along each lateral edge thereof and one in which a single linear support member is joined to the wear member along one lateral edge thereof.

Abstract: This is a method of and apparatus for forming a trench in the ballast under railroad track, commonly referred to as scarifying, and for grasping new ties, one at a time, positioned on top of the rails, drawing each tie in turn out to one side, positioning it opposite the trench and inserting it, all in a series of coordinated movements in sequence with a minimum, if any, disturbance of the ballast.

Abstract: The outer section of a rotary mower blade is stamped with a U-shaped cut-out portion to define a tab extending in the direction of the center of the blade. Each tine device is formed of springwire and includes a downward end section which forms the tine and a coiled section which is mounted on the tab. The other end section overlies the mower blade to prevent rotation of the entire device on the tab by the operation of the tine which is to loosen the thatch formed by accumulated grass clippings.

Abstract: This is concerned with the coating or composition for use as a coating to be applied to surfaces subjected to wear to increase the life of the surface by resisting excessive wear thereon where the surface is subjected to a high abrasion or an abrasive atmosphere. The coating is intended to be trowelable, meaning that it can be applied with a trowel or any similar tool or instrumentality which enables it to be applied at the site or on the job.

Abstract: This is concerned with a so-called gyratory crusher bowl clamping system in which a screw-threaded bowl is rotated for adjustment and a so-called rocker arm pressure-off clamping system is provided which avoids dirt, dust and sealing problems. The crusher includes a frame which is greatly simplified, but has increased strength and rigidity as well as a support for the crushing head that greatly simplifies manufacturing and machining problems.

Abstract: This is concerned with an electric circuit for controlling or damping the shock loading on the structural components and parts of machinery which are moved by a conventional hydraulic cylinder. It is more specifically concerned with a control circuit to be used with a proportional control valve so that the mass moved by the cylinder will be gradually accelerated and decelerated to avoid abrupt starts and stops.

Abstract: This is a machine for doing work on railroad track and includes a mechanism for setting new tie plates on top of ties so that a new rail may be accurately positioned thereon. The machine is specifically constructed and arranged to accurately set the tie plates so that they do not require further adjustment prior to laying the new rail. The machine is self-propelled and automatic so that it does not require an attendant, other than possibly personnel to feed tie plates to it.

Abstract: This is concerned with a method and apparatus for sensing and/or finding objects along railway track, for example a tie, so that work may be done in relation thereto. More specifically, the subject matter is concerned with a method and apparatus for finding ties on a step-by-step basis and performing work in relation thereto, for example tamping between the ties or driving spikes through the holes in tie plates into the ties, or the like.
