  • Patent number: 5931276
    Abstract: An adjustable chute for X-ray sheet film having different film formats. The chute is further developed in such a way that sheet film received from a cassette loading and unloading station of a daylight cassette loading and unloading device is to be centrically introduced into, and deposited in a light-tight collecting magazine. For this purpose, the chute comprises two guide holders which are arranged in one plane for guiding sheet film from the loading and unloading device into the magazine. The guide holders are pivotable about oppositely and fixedly spaced pivot points for providing an input opening for the sheet film. Setting device arranged adjacent to an output opening of the chute centrically adjusts the guide holders to the film format of the sheet film supplied to the magazine.

  • Patent number: 5513581
    Abstract: A distributor chute for bulk material, in particular for use in a bell-less blast furnace top charging device, has several inclined transverse plates in the region of its impact zone. The transverse plates create retaining pockets between their inner faces and the surface of the distributor chute. Two adjacent transverse plates limit between the outer face of the first transverse plate and the inner face or the second transverse plate a retaining chamber. If the inclination of the chute is reduced, the bulk material moves from the retaining pocket to the retaining chamber.

  • Patent number: 4795018
    Abstract: A high speed gravity feed can conveyor comprises two facing C-shaped guides formed of hard chrome plated sheet metal. The guides are held in opposed spaced relationship by open U-shaped collars distributed along the conveyor. The collars distributed along the conveyor. The collars are formed with openings positioned downward having sufficient width to pass a can turned from a rolling orientation in the conveyor. The edges of the C-shaped guides are turned in a direction to support a rolling can and are covered with ultra-high molecular weight plastic to minimize rolling friction and protect the metal surface. The facing guide surfaces with chrome plating reduce sliding friction when a can end contacts a guide and reduce the potential for nicking the surface.

  • Patent number: 4684309
    Abstract: A system, apparatus and procedure for processing tubular or cylindrical stock, particularly short lengths thereof, into precision formed end products includes a chute, preferably formed of a pair of parallel wall surfaces mounting opposed guide plates at least a portion of which are adjustable. The orientation of the chute and its cross section are made such that in the delivery thereof the longitudinal axis of the stock is maintained substantially parallel to the position in which such axis must be set for the working thereof. A transfer device cycled to and from the delivery end of the chute successively receives elements of the stock discharged therefrom and carries them to a work station without change of their orientation. Upon reaching said working station, said transfer device first holds the stock loosely against a complementary abutment surface, essentially in the attitude required for the working thereof.

  • Patent number: 4539794
    Abstract: X ray films are withdrawn from a drawer type magazine positioned above an X ray film cassette unloading station. The films drop down freely from the magazine through a hopper and towards the said X ray cassette. The hopper comprises two substantially U shaped guide elements, one placed opposite the other in such a way as to form two channels along which slide the edges of the two opposite sides of each individual film. One of the elements is fixed, while the other is supported in a sliding fashion by the frame of the machine. The sliding element is able to undergo, in the direction of the fixed guide element, a two way displacement, and is connected to a pusher device provided on the machine for positioning the X ray cassette inserted into the unloading station, up against an abutment member located on the same side of the machine as the fixed guide element.

  • Patent number: 4403686
    Abstract: A modular chute assembly for transportation and removal of parts and scrap from production operations in a manufacturing facility. The modular chute assembly is designed to be readily adapted to a variety of special chute configuration requirements and needs. Many complex chute layouts can be attained using the same relatively few basic chute components or modules. The modular chute system is also strong, lightweight, and inexpensive.

  • Patent number: 4099607
    Abstract: The aperture mask conveyor and inspection system comprises a pair of belt conveyor assemblies which between them grip and transport an aperture mask from the end of the processing unit to a chute assembly which chute assembly feeds the mask onto a belt conveyor, a densitometer is centrally positioned on the belt conveyor to provide a measure of the amount of light transmitted through the center portion of the mask which is passed beneath the densitometer. After passing under the densitometer the mask is deposited on an adjacent tray.
