Abstract:
An earth working scraper (10) for use removing and transporting earth is disclosed. The scraper includes a scraper blade (12) for scraping earth from a ground surface, a receiving area located near the blade for receiving earth scraped from the ground surface by the blade, a rotatable axle (16), connected with respect to the blade and receiving area, for providing transportation of the scraper, and a track apparatus (20) connected with respect to the rotatable axle. The track apparatus may include a continuous flexible track (22) having an upper length (23) and a ground-engaging lower length (21) and including an inner surface (24), an axle wheel (26) mountable to the rotatable axle for rotational movement therewith, the axle wheel engaging the inner surface of the flexible track along the upper length to drive the flexible track in response to rotation of the axle, and a frame (28) for mounting the axle wheel.
Abstract:
A system, and corresponding method for its use, for performing various monetary transactions in a vehicle such as an aircraft, including exchanging one currency for another, obtaining currency using traveler's checks or a credit or debit card, and dispensing value cards purchased with cash or credit/debit cards. The value cards may be, for example, long-distance telephone usage cards or gaming cards, and the value cards may be increased in value or exchanged for cash using the system of the invention. A key feature of the system is that cash is always distributed in the currency of the next destination of the aircraft, as determined from flight management system data availabe on the aircraft. At each intermediate destination, a note dispenser is conditioned to dispense only the currency of the next destination.

The bogie-suspension apparatus comprises (a) a bogie assembly having a bogie mount, at least one rotatable ground-engaging bogie wheel thereon, and forward and rearward bogie-mount connections; (b) first and second load- and ground-responsive suspension joints spaced from one another in a forward/rearward direction; and (c) leading and trailing suspension elements each having an upper end and a lower end, the upper ends of the leading and trailing suspension elements rotatably attached to the first and second suspension joints, respectively, and the lower ends thereof rotatably attached to the rearward and forward bogie-mount connections, respectively.
Abstract:
A vehicle track-module (10) including an upper drive wheel, a plurality of idler (14A and 14B) and bogey wheels (15A and 15B), and an endless rubber track (16) with spaced lugs (20) which extends around the wheels and is driven by the drive wheel (12), which has: a middle main plate (22) with a outer edge (40B) of first diameter and inward and outward sides (28A and 28B) forming the exposed inward and outward surfaces of the drive wheel; drive members axially across and projecting radially beyond the main-plate edge (26) to a second diameter.
Abstract:
A continuous flexible track (12) for extending about a plurality of aligned wheels on a vehicle or track module (10), the track includes an outer ground-engaging surface (22) and an inner wheel-engaging surface (24) having inwardly-projecting wheel-engaging lugs (26). Each lug has a proximal end (32), a distal surface (34), front and back surfaces (36, 38) and opposite side surfaces (40, 42). Each lug further includes a flex-groove (44) extending between the side surfaces and from the distal surface toward the proximal end, thereby dividing the lug into two portions to allow around-wheel hinging motion. In most preferred embodiments, a lug-receiving cap (50) may be positioned over and replaceably secured with respect to each lug. A method for prolonging the useful life of such a track is provided.
Abstract:
In vehicle track-module apparatus including a module frame, a drive wheel rotatable with respect to the frame, ground-engaging leading and trailing wheels, at least one ground-engaging bogie wheel, and an endless track extending around the wheels and driven by its engagement with the drive wheel, the improvement comprising: (a) a leading suspension arm rotatable with respect to the frame and extending forwardly to a distal end at which a leading-wheel assembly is rotatably attached and rearwardly to a rearward suspension end; (b) a trailing suspension arm rotatable with respect to the frame and extending rearwardly to a distal end at which a trailing-wheel assembly is rotatably attached and forwardly to a forward suspension end; (c) a bogie assembly having a bogie mount and the at least one bogie wheel rotatable with respect thereto; and (d) leading and trailing suspension elements rotatably attached to and extending from the rearward and forward suspension ends, respectively, to rearward and forward rotatable bogie-mount connections, respectively.
Abstract:
A soil stabilizer (10) for use treating earth is disclosed. The soil stabilizer includes astabilizer frame (12) , a rotor (14) rotatably mounted with respect to the stabilizer frame, the rotorincluding a cutting tool for cutting earth and being movable with respect to the ground surface(23) such that the rotor may engage various depths of earth, a rotatable axle (116) for providingmovement of the soil stabilizer to move the stabilizer frame and rotor across the ground surface,the axle connected with respect to the stabilizer frame, and a track apparatus (120) mounted onthe rotatable axle, the track apparatus supporting the stabilizer frame and providing formovement of the stabilizer frame and rotor across the ground surface. The track apparatus mayinclude a continuous flexible track (122) having an upper length (123) and a ground-engaginglower length (121) and including an inner surface (124), an axle wheel (126) mountable to therotatable axle for rotational movement therewith, the axle wheel engaging the inner surface of theflexible track along the upper length to drive the flexible track in response to rotation of the axle,and an apparatus frame for mounting the axle wheel.

Abstract:
A permanent magnet assembly particularly useful in magnetic resonance studies includes a central spacer (C) having opposite shallow recesses (96, 98) therein receiving end portions of pole pieces (30, 40) for aligning same. Main permanent magnets (F, G) abut the pole pieces on the opposite sides thereof from the central spacer (C). The main permanent magnets outwardly overlap a peripheral interface (38, 48) between the pole pieces and a plurality of side permanent magnets (32a, e, 42a, e) for minimizing flux leakage at such interface.
