Abstract: A lubricating system which uses a chain sprocket to determine the precise chain pin location and deliver the lubricant to preselected points along an endless moving chain is disclosed. In accordance with the invention, steel bars or plates are mounted on alternate sprockets or gear teeth such that as the sprocket rotates the steel bars pass in proximity to a magnetic sensing means which creates a signal to energize fastacting solenoid valves so as to cause the lubricant to be delivered through lubricant nozzles positioned in alignment with the links of the chain.

Abstract: An improved conveying apparatus and an electronic control module for conveying systems is disclosed. The conveying apparatus includes two or more belt conveyors operating in tandem and is controlled by separate electrical circuits so that each conveyor in the system operates independently and on automatic demand of a given or preset response. The electrical control for the conveying system includes a timer which is adapted to time each object being conveyed to transverse the length of the conveyor and to stop the conveyor when the object is not present along the length of the belt. The timed circuitry further includes a memory function so that if a conveyor stops for any reason, it will restart and operate for the unexpired segment of the time required to provide a total cycle. This assures that the object being conveyed is never left on a conveyor belt unintentionally and eliminates all unnecessary operation or running of the conveyors.

Abstract: A new bleed, smudge and eradication resistant ink composition for use in the cancellation of stamps and marking of paper products consisting essentially of 2-ethyl-1,3-hexanediol, polyethylene glycol having a molecular weight in the range of 380 to 420, C.I. Solvent Black 28, triethanolamine chelate of orthotitanic acid, octylphenoxy polyethoxy ethanol having 5 ethylene oxide units, and octyl-phenoxy polyethoxy ethanol having 9 to 10 ethylene oxide units.

Abstract: This document discloses the use of reduced heteropoly acids as additives to absorbing material to impart reduced infrared reflectivity or transmission thereto. The reduced infrared reflectivity is especially suitable for use in inks for reading bar coded and optical character reader mail by a special sensing device wherein the infrared portion of the spectrum is betwen about 700 and 1000 nanometers. It is also useful in plastics, aqueous solutions, photographic screens, and paints.
