The collector assembly includes a pair of rollers having a plurality of flexible fingers disposed radially on the periphery thereof, the rollers being substantially parallel to each other and disposed in a plane that is substantially parallel to the ground. The rollers are arranged so that the fingers on one of the pair of rollers intermesh with the fingers of the other of the pair of rollers so as to be able to lift litter between them. The apparatus further includes a device for conveying litter lifted by the pair of rollers to the hopper.

Abstract: Resilient stoppers are temporarily compressed and are inserted into tubular conduits and then released to expand therein to stop fluid leakage therefrom. Tapered stoppers larger across than tubes to be plugged are inserted by a tapered hollow tool having a large end to receive a stopper and a smaller end inserted within a tubular conduit to be plugged. Application of pressure to the base of the stopper to force it through the tapered tool also compresses it to a temporarily lesser size. Upon leaving the tool end inside the tube, the stopper expands into non-slipping contact with the surrounding wall. Continued pressure, rather than sliding the stopper in the tube, backs the tool end away and out therefrom, leaving the stopper plugging the tube.

Abstract: A squeegee device including a mount carried pivotally from a handle for mounting a squeegee blade in a normal position for sweeping the majority of the distance across a window pane recessed in a window opening defined by abutment walls of, for instance, a high rise building. The mount is biased to the normal position by a bias spring and a kicker arm is carried on such mount. The kicker arm is constructed to, when the apparatus approaches completion of the stroke, engage the abutment wall forming the window opening to orbit the mount and consequently such blade through an arc relative to the handle thereby accelerating movement of such wiper blade to complete the wiping stroke.

Abstract: Apparatus for broiling whole chickens which have been severed along the breast bone for opening into a generally flat condition includes a housing having opposing laterally spaced sets of upright gas-fueled infrared heaters defining therebetween a cooking chamber and an endless chain conveyor for transporting chickens suspended by their legs through the chamber. Plural pairs of support forks are spaced along the conveyor for suspending one chicken carcass by its legs from each fork pair with the legs sufficiently spread from each other to maintain the chicken in the opened generally flat condition. A spaced pair of deflector plates are provided along the conveyor following the cooking chamber for discharging both legs of each chicken simultaneously from the pair of support forks suspending the chicken.

Abstract: A portable concrete batch plant which may be pulled from one location to another and which may be used either as a transit mix batch plant or a central mix batch plant. The batch plant is mounted on a wheeled frame comprised of a rear frame section and a front frame section removeably secured thereto. The batch plant is transported from one location to another with the rear and front frame sections connected together. If the batch plant is desired to be used as a transit mix plant, the front and rear frame sections remain connected together. If it is desired to use the concrete batch plant as a central mix batch plant, the front and rear frame sections are separated with the front frame section being spaced horizontally and vertically from the rear frame section with an extension conveyor being positioned there between.

Abstract: A solid-bowl centrifuge with an intake pipe and a peeling disk that conveys the peeled-off material out through its hub and comprises a stationary eccentric and a rotating lid that allows the disk to rotate on a carrier positioned in a radial slot. The hub comprises two concentric components, wherein the inner component is secured to the stationary eccentric and the outer component is secured to the rotating peeling-disk lid.

Abstract: The peeling chamber in a head of a centrifuge has an upstream barrier chamber that seals it off from the atmosphere. A barrier disk secured to a peeler extends into the barrier chamber. Compressed gas is supplied to between barrier disk and peeler through a channel to prevent gas from escaping from the solvent. Another channel supplies liquid to the barrier chamber. Solvent from the periphery is supplied to the barrier chamber through a channel and simultaneously by the peeler through the barrier-liquid channel. An area of separation becomes established between the two liquids in the barrier chamber. If any solid particles enter the barrier chamber as the result of gas leaving the solvent, they will dissolve again in the solvent in the periphery of the barrier chamber and will be prevented from making the chamber malfunction.
