Abstract: A machine for adjustably placing a low dam moving along each lateral edge of a Fourdrinier fabric so as to contain the paper-making slurry on the fabric without leaking over the edges of the fabric while the moving fabric is subjected to sufficient suction treatment to render the slurry immobile on the fabric. The principal object of this invention is to maintain the slurry in a steady flow pattern substantially free of any waves while the slurry is forming a self-supporting paper web.

Abstract: A signal comparator receives switch-created signals from two stations manned by an engineer and a trainman in a locomotive and compares the signals for a match. The signals are an implementation and acknowledgement of wayside signals. One station is used to acknowledge a signal and unless a match is determined by the other operator entering the same acknowledgement within a preset time interval the system will automatically stop the train. Alarm functions and speed monitoring functions based on matched station signals are also provided. The system is automatically activated anytime a switch is operated or the speed of the train exceeds 15 mph. Signal matching is also required at period time intervals. If such acknowledgement is not forthcoming, the system assumes crew incapacitation and will automatically stop the train.

Abstract: This invention provides eye-protecting shields or chambers that are sealed against the facial skin by an adhesive pliable foam or sponge rubber layer about a face conforming flange with a bulbous clear portion not touching eyelids or the eyelashes. The shields can be ventilated to the atmosphere through a planar flap outwardly of a flat cutout adjacent an outer corner of an eye. Access to the eye may be secured via openable flap for the introduction of medicaments to the eye. In a specific embodiment the access to environmental air may be controlled by a selective access valve and a moisture or medicant pad may be carried by the flap inwardly of the shield. A releasable catch between the flap and the bulbous portion permits self-closing and retention of the flap. A pair of shields with an elastic member therebetween provides a pair of spectacles which may include an elastic or adjustable headband with releasable fastener(s).

Abstract: An apparatus and a process for subjecting a free falling stream of particles to an electrostatic field, between two rows of oppositely charged electrostatic rotating electrodes to effect a separation between particles of different electrostatic properties; the electrodes and cleaning brushes being suspended vertically and driven from their upper ends and having free lower ends. The electrode bearings are gently flushed with air from inside the electrodes and brushes to minimize the accumulation of dust thereon. The feed stream is baffled to minimize any lateral movement of the feed particles. The electrodes are fitted with commutator mechanisms to permit efficient and unchanging electrical charging of the electrodes without a separate connection from the power source to each electrode, i.e., the charging is from one to the next adjacent electrode.

Abstract: A process and an apparatus for separating particles according to the strength of their magnetic susceptibilities includes a mass of loose particles transported on a moving surface over a plurality of long, thin, magnets separated by thin straps of ferromagnetic metal. The magnets are arranged such that the polarities of two adjacent magnets engaging opposite sides of the same ferromagnetic strap are identical. Particles are separated on the moving surface and when that surface passes around a horizontal axis, the particles fall off the surface into selected areas according to the magnetic susceptibilities of the particles. Cooling air flows between the moving surface and magnets to enhance operation and the useful life of the magnets.
