Abstract: A passenger loading method and installation is provided by means of which passengers are mechanically propelled and accelerated to a velocity substantially the same as that of a main transport structure onto which they can be loaded without the necessity of stopping or slowing movement of the main transport structure. The invention is particularly applicable to ski-lifts and enables an increase in hourly carrying capacity of such lifts.

Abstract: A transportation system includes pallet cars coupled with one another; the pallet cars being for the positive non-slipping transportation of baggage conveyor cars for escalators. On the lower side of the pallet cars, arc-shaped drivers are pivotably mounted about one of the carrying axles constituting a pivot point, by means of a bracket. The drivers are supported on a track via a roller secured at a pivot point on the driver such that during the transportation operation the driver projects through a slot in the pallet car and engages in back of a catch which is secured at the bottom of the baggage conveyor car. Shortly before reaching the horizontal part of the transportation system the driver disengages from the catch of the baggage conveyor car.

Abstract: The invention refers to an apparatus for disposal of cut end portions in a multistrand casting plant, particularly in a twin strand steel slab strand casting plant, consisting of vehicles moving on a rail track in a position in the strand paths following the separating or cutting device in vertical direction and positioned between the conveyor path rollers of the parallel casting strands. Such vehicles are provided with a bearing surface for the cut end portions just below the conveyor path transport level. The rail track connects the conveyor paths of a strand with a discharge station.

Abstract: A conveyer system including a power line with a running rail and a running chain, a horizontal free line with a running rail, a running belt and a stopper, and trolleys wherein the trolleys are brought into contact with the belt which runs along the running rail of the free line and are transferred along the free line by frictional force with the running belt. The stopper provided on the free line running rail may halt the trolleys against the frictional force of the belt.

Abstract: Traveling support apparatus for supporting welding device or other apparatus for peripheral travel about a pipe. The support apparatus utilizes endless belts disposed around paired wheels at opposite sides of the apparatus to propel the apparatus along a track. The endless belts are pivotally supported for equal pressure engagements with the path along which the support apparatus travels. The support apparatus engages opposite sides of a track in the form of a strip or band spacedly surrounding a pipe to support a frame which is held firmly against movements toward or away from the track so that the supported apparatus is reliably held in position with relation to the pipe.

Abstract: A continuous transport system characterized in that the vehicles providing passenger or goods transportation are passive vehicles without self-contained motors or braking devices, the drive for these vehicles when formed into trains being provided between stations by a head locomotive and a tail locomotive.

Abstract: This transport system for transferring passive vehicles such as cars, platforms, containers, by means of a continuous-drive conveyor is characterized in that each vehicle comprises, in addition to carrier wheels engaging the main and fixed carrier rail, at least one tire-mounted wheel carried by cross beams projecting laterally from the vehicle, the tire-mounted wheel being adapted to engage intermediate retarding or acceleration tracks, a skid mounted in parallel relationship at the end of the cross beams and adapted to engage endless belts driven at low linear speeds for embarkment and disembarkment purposes, and also for transferring the vehicle to turnaround turntables at the ends of the system, and another skid adapted to engage the main endless belt conveyor for driving the vehicle at high speed.

Abstract: A device for transporting sliced comestible product from a slicer and loading the product in packages includes a belt drive system, with a plurality of transfer carriages supported thereon, extending between the slicer and the loader. Each transfer carriage includes a grid of horizontal, parallel tines to support the product. The loader includes a loader carriage slidably depending from a track, and a plurality of hooked tines pivotably secured to the loading carriage. The hooked tines are adapted to rotate down between the transfer tines to remove the product therefrom as the loader carriage translates along the track toward the package to be filled. The loader carriage stops above the package, where side guides grasp the sides of the product as the loader tines swing away. A loader plunger then descends to urge the product into the package. The transfer carriages are slidably supported on the belt drive system, so that one or more transfer carriages may be temporarily stopped on the belts.

Abstract: A mechanism for moving one or more first load supporting hangers through a predetermined path that is defined by the interior of a hollow longitudinally slotted first frame. Each hanger is rotatably supported from a first ball that is movably supported within the first frame. The interior of the first frame not filled with first balls is filled with second balls. A first wheel that has pairs of spaced lobes on the circumference thereof projects through an opening in the first frame, with the pairs of lobes sequentially engaging the balls when the first wheels is rotated. The first and second balls and the hangers supported from the first balls are moved longitudinally in the first frame as such sequential engagement of the balls takes place. Should it be desired to move a platform having first and second ends through said predetermined path, the first end is connected to the first hanger, and the second end to a second hanger.
