Abstract: Apparatus and a method are disclosed for transporting a motor scooter or similar type vehicle on the back of a motor vehicle such as an automobile, van, pick-up truck or the like. The apparatus of the present invention attaches to the rear of the motor vehicle and includes a platform which, when not in use, is oriented in a vertical direction. When the apparatus is used to transport a motor scooter, the platform is lowered to the ground and the motor scooter can be loaded onto the platform. A restraining bar is used to secure the scooter to the platform. The platform, still with the horizontal orientation, is raised to prevent contact with the ground when the motor vehicle is in motion. To remove the motor scooter, the platform is lowered to the ground, the lowering of the platform causing the restraining bar to be released. The motor scooter can then be removed from the platform and the platform secured in a vertical orientation until required further.

Abstract: The present invention relates to a new and improved trailer for unloading large cylindrical bales of hay. The trailer has a simple rectangular frame that holds hay bale carriers in place by a dual latch/keeper assembly mechanism. The dual latch/keeper assembly allows the cradle to tilt in either lateral direction to dump the hay bales on either side of the trailer. As a safety factor for the operator, the release for the latch/keeper assembly is on the opposite side from the side upon which the carrier dumps. The present invention may include a pedestal which holds a hay bale cradle over the wheels. The pedestal is removably mounted so that both the pedestal and the pedestal cradle can be removed thereby allowing the trailer to carry goods other than hay, such as irrigation pipe. The raised pedestal also allows for fenders over the wheels of the trailer. Fenders and lights are provided to ensure that the trailer is street worthy.

Abstract: A method of palletizing and depalletizing stacks of products in continuous, layer-by-layer succession, the products being substantially flat and thin, such as folded sheets of paper, in which a fully automatic mode of operation is achieved by depositing the stacks of a stack layer on an intercarrier in order to load a pallet. Transport elements, which are associated with a loading and unloading station, may be positioned beneath the stacks and caused to move through or into the intercarrier in order to effect the deposition on and lifting from an intercarrier of stacks which partly defines a stack layer, the stack layers and the associated intercarriers being stacked on a pallet, as a unit, and being destaked from the pallet in like manner.

Abstract: A prestressed concrete railroad tie having a tie body made up of two end members for supporting rail attachment parts and a central section extending between and interconnecting the end members and having a transverse cross-section smaller than the transverse section of the end members. Tendons are located in the tie body and extend in opposite directions from a common vertical or horizontal plane in the central section into the end members. At tie ends of the end members the tendons are anchored and are uniformly distributed across the transverse cross-section of the end members. With the tendons centered in the central member, a narrow central member is afforded. The tendons fan outwardly from the common plane in the central section into the end members providing wider or larger end members. This prestressed concrete tie arrangement affords only low changing bending moments in the central section or a positive course of bending moments across the length of the tie.

Abstract: A loader mounting arrangement includes a pair of mounting frames secured to the opposite sides of the tractor frame for receiving the lower ends of the loader mast posts. Each bracket includes a transversely extending pin for receiving a C-shaped forwardly opening front portion of the mast post. The rear of the mounting frame opens upwardly to guide the aft portion of the mast post end as the mast post is rocked downwardly about the axis of the rod. Projecting pin-receiving bushings in the aft portion of the mast post end are received within mating upwardly opening pockets in the mounting frame. The bushings are positively forced into the pockets by operating the boom lift cylinders with the loader attachment on the ground to assure alignment of the mast post end and the bracket. With the bushings forced downwardly into the fully seated position within the pockets, hole in the bracket are aligned with the bushing bores, and a locking pin is easily inserted to secure the mast post to the tractor.

Abstract: An article handling device for attachment to the rear of a pickup truck including a rigid main frame having arms separated by a cross member and all lying in substantially the same plane. The cross member has rigidly attached at approximately 90 degrees thereto a leverage pole to rotate the main frame when it is hingedly supported on a bumper mounting base. A floating spear type axle for retaining an article on the main frame is attached thereto near the outer end of each arm by a flexible movement limiting tether. The floating axle when penetrating and thereby retaining an article such as a round bale allows the bale to shift downwardly and rest on the main frame preventing transit damage especially to loosely packed or soft core bales.

Abstract: A railroad flat wheel detector having a housing anchored to one side of a railroad rail enclosing an arrayed plurality of light source-photodetector pairs whose respective optic axes are tangent to the locus of the lower rim edge of passing wheels rolling along the track. The photodetector outputs are operatively connected to trigger a flat wheel alarm when the increased wheel flange rim overlap with the supporting rail, caused by a flat sector of a passing wheel, obscures a portion of the light and thereby briefly reduces the light intensity sensed by one or more of the plurality of photodetectors.

Abstract: A method of handling and securing platelike substrates, such as wafers, is described in which a substrate is gripped between supporting elements situated opposite each other in the plane of the substrate to be applied against opposite side edges of the substrate. The gripping forces are applied through resilient means in order to limit the gripping force applied. Apparatus for gripping a substrate in accordance with this method has the supporting element or elements on one side in a fixed position and the other movable towards the substrate to apply the gripping force, the resillient means being disposed between said other element or elements and the driving means for said movement. There is also described an optical sensing system for positioning the supporting element relative to a substrate.

Abstract: A queue of randomly oriented chips is advanced down a track. Each chip in the queue is sequentially and individually elevated into a pneumatic circuit and pressed against a mirrored surface of an upper slide member to which it adheres if the chip was oriented with upwardly disposed solder lands. A jet of compressible fluid insufficient in magnitude to dislodge the chip is injected in a direction toward the queue. If the chip, alternatively, was oriented with the solder lands down, this fluid jet propels the chip about the oval-shaped pneumatic circuit so as to reorient the chip with the lands extending in the desired upward orientation, whereupon the chip is injected into a storage magazine.

Abstract: A ramp lifter device is provided which is adapted to elevate the end of a loading ramp from its initial, extended position to the floor height of a trailer. A trailer chassis provides a storage area for the loading ramp between longitudinal frame members. A ramp carrier box is secured between opposing frame members of the trailer chassis. The ramp includes a ramp carriage having extension rods that are slidingly received along the ramp carrier box. The ramp lifter device includes a reinforcement member attached to a bottom cross member towards one end of the ramp, and a handle. Selectively applying a downward force on the handle forces a pivot rod on the ramp lifter device against the ramp carriage extension rods, which pivots the reinforcement member upwardly, and hence elevates the end of the ramp to the level of the trailer floor. The loading ramp can be manually moved forward and lowered so that ramp hooks on the end of the ramp engage corresponding ramp pockets on the end of the trailer body.

An offset of 120.degree. from end to end allows only one port to be opened at a time. The assembly is made of stainless steel or aluminum and clear acrylic plastic to enable visual observation. The assembly allows transfer of swipes and smears from radiological and other specially controlled environments.

Abstract: An apparatus for separating and counting coins comprising a pair of rail spaced from each other to define a coin slot and a closed-loop chain for stably moving coins of different diameters on the pair of rails. The two rails are inclined with respect to a horizontal plane so that the coins are supported thereon in an inclined manner. The coin slot increases incrementally from an upstream of the coin slot to a downstream of the coin slot. Each coin, which has a diameter larger than a first width of the coin slot at the upstream and smaller than a second width of the coin slot at the downstream and moves along the coin slot, falls from the pair of rails. A counting device is suitably provided near the coin slot so that, upon falling of the coin, a count is registered.
