Abstract: A single copy newspaper vending machine in which a telescoping rod assembly is activated via a comparative and memory electronic circuit. Data is read into the circuit by means of a magnetic card and reader. The apparatus and method provide a guaranteed newspaper sale since the magnetic card must be utilized by the subscriber in a specified machine and on a specified date. The system results in increased advertising revenues for newspaper publishers and in added convenience for newspaper subscribers.

Abstract: A newspaper insert cart including a braking assembly which allows the cart to be stopped and rotated for convenient unloading of various sections. The braking assembly structure is specially designed for reliability, durability and a positive braking action. It also results in an overall system which is much less likely to cause injury to the cart user than systems heretofore known in the prior art.

Abstract: A lubricating device for railway car center plates comprises an annular disc of hardened steel plate having a maximum diameter slightly less than the diameter of the truck center plate and an inside diameter substantially greater than the center plate center pin holes, the annular disc being of substantially harder steel than the opposed surfaces of conventional truck and body center plates. The plate is enveloped in a viscous lubricant and is formed with a plurality of holes distributed generally uniformly throughout its surface area and these holes are also filled with lubricant, such that upon relative rotation between the truck and body center plates and during relative radial movements of the annular disc with respect to the truck and body center plates accommodated by horizontal clearance between the periphery of the annular disc and the truck center plate side walls, lubricant is distributed between the top and bottom surfaces of the plate respectively and the body and truck center plate surfaces.
