Abstract: Mixtures of particulate material of widely different particulate sizes segregate on storage, smaller particles falling to the bottom. In the invention mixture is supplied to a bunker in a plurality of layers and subsequently withdrawn so that mixture is taken from each layer simultaneously. Apparatus used comprises a rotor dividing the bunker into several equal compartments. During introduction of a batch of mixture to the bunker the rotor is rotated through several revolutions so that the mixture forms layers in each compartment. The bottom of the bunker is flat. An outlet slot in the bottom extends along a chord. A crew conveyor below the slot carries mixture falling through the slot away from the bunker. The rotor rotates slowly during dispensing in synchronism with the conveyor, pushing mixture to the slot at such a rate that material from every layer in a compartment falls into the slot simultaneously, the compartments being progressively emptied.

Abstract: A manually operable mechanism for attachment to the adjustable stage of an inspection microscope for lifting a selected printed circuit wafer from its slot in a conventional disc holder and positioning it under the microscope lens for inspection. After inspection the mechanism is operated to lift the wafer from its inspection position, to transport it back into the disc holder, and carefully lower it into its correct slot. There is no manual handling of the wafers and therefore the normal losses resulting from breakage and contamination is eliminated.

Abstract: Storage installation permitting the automatic selection and removal of articles stored at different levels on carrying elements of one or more shelf units, each carrying element (5) being fitted with a device for transporting the articles and with an individual and self-governing control member (6) for actuating this transporting device. The articles removed in this way can be grouped and moved by a common transporting means towards a central packaging and distributing station.

Abstract: A grain elevator utilizing pre-cast concrete elements includes a plurality of vertical rows of bins, which slope from front to back to an angle of approximately 30.degree., the front ends of the bins being located above office, receiving, grain cleaning or shipping and agro-product warehouse space; a tower or cowl at the front end of the elevator housing bucket elevator heads and distribution conveyors for loading the bins; a discharge manifold for removing the grain from the lower, rear ends of the bins, and conveyors for delivering the grain to trucks or to bins for feeding the grain into railway cars.

Abstract: Apparatus for handling elongated objects such as pieces of wood includes at least one elongated flexible member for forming the bottom and sides of an object-handling compartment having a longitudinal dimension and a transverse dimension, the flexible member having a first end and a free end; a coiling device associated with the first end of the flexible member for winding up and unwinding the flexible member; an attaching device at the free end of the flexible member; an attaching mechanism operable for selectively being connected to and disconnected from the attaching device whereby when the attaching device and the attaching mechanism are connected, the flexible member can be suspended from its ends to form the compartment and whereby the attaching device can be disconnected from the attaching mechanism to loosen the flexible member to enable emptying of the compartment; and a device arranged after loosening of the flexible member to introduce the flexible member in the attaching mechanism so as to bring t

Abstract: A grain handling transfer and storing system including a plurality of bins in two rows in circular arcs about a center pad, each of the bins or receptacles having ground level discharging conveyors and open tops for filling, a pair of screw conveyors radially arranged from the center of the open space between the bins, with distal ends supported on wheeled carriages and proximal ends on a swiveling mounting carried by a tripod and a swiveling housing permitting swinging of the screw conveyors.

Abstract: A grain drying apparatus includes an upright bin having a perforated drying floor supported substantially above a perforated cooling floor. An opening through the drying floor communicates with a hopper having a gate mechanism adapted to confine grain within the hopper when closed and adapted to permit grain to fall from the hopper into the cooling chamber when opened. A grain discharge conveyor has one end in communication with the hopper and the other end extended outwardly through the bin sidewall. A support truss for the drying floor includes upper and lower ring members supported in vertically spaced-apart and aligned relation, a plurality of purlins radiating outwardly from the upper ring member for connection to the bin sidewall at circumferentially spaced positions and a plurality of tension braces radiating outwardly from the lower ring member for connection to the purlins adjacent the bin sidewall.

Abstract: A sort bin having substantially vertical bin walls and a vertically movable bin floor, the floor being mounted such that it is in a predetermined and fixed inclined attitude throughout its vertical movement.

Abstract: An elevator mechanism for an automatic teller machine, equipped with a plurality of bill dispensing modules for dispensing bills at a plurality of elevations, incorporates a tray adapted to be raised and lowered by drive apparatus, the tray being rotatably mounted on a bracket and adapted to normally assume a horizontal position during its upward motion, during which it collects bills dispensed from the bill dispensing modules, an access door located at the top of the elevator assembly and an assembly for unlocking and lifting the door as the tray reaches its upper position. The tray is tilted during its downward movement so that any remaining contents of the tray are deposited into an escrow compartment.

Abstract: An apparatus and method are disclosed for blending flowable solid materials. These are conveyed in turn, conveniently over a belt weigher, to a tripper mounted above a hopper so as to build up a first charge consisting of a plurality of inclined contiguous bands each of a different material. A paddle feeder removes material in a series of passes along the bottom of the first charge, the material removed being conveyed again to the tripper for discharge into a second hopper adjacent the first, thereby to build up a second charge also consisting of a plurality of inclined contiguous bands each of a different material. A second paddle feeder then removes material in a series of passes along the second charge to form the final blend.

Abstract: The present disclosure is directed to a mobile side-by-side batching plant wherein the aggregate storage bins are disposed end-for-end along one side of the longitudinal center line of the supporting, transporting frame. The cement storage bin is disposed in continguous substantially coextensive relation therewith, along the other side of the center line of the supporting transporting frame. Batching conveying and handling means are provided in receiving relation under the several storage bins for the reception proportioning and delivery of selected aggregate and cement.
