An instrument for measuring blood pressure by sensing the Korotkoff sounds which prevail only between the systolic and the diastolic points. The instrument used is essentially a hand held device which is held in direct contact with the skin over an artery. The instrument has a pressure-sensitive element which responds to pressure, and a crystal transducer which responds to Korotkoff sounds. A pressure is exerted on the instrument occluding the artery and stopping the Korotkoff sounds, and, as the pressure is reduced and the Korotkoff sounds commence, the crystal transducer senses the vibrations from the artery which vibrations are Korotkoff sounds. The crystal triggers a memory circuit, the contents of which are shown on the digital display. The digital display shows the pressure sensed by the strain gauge at the time the sounds appear at the systolic point and again at the diastolic point.

An apparatus to alert a deaf person made up of an alarm device such as a smoke detector adapted to vibrate when actuated by smoke and a transmitter having a vibration sensor connected to the transmitter. The vibration sensor is supported in engagement with the smoke detector and adapted to sense the vibrations of the smoke detector and to transmit a signal to a remotely located receiver. The receiver has a vibrating reed with a tacticle member on its end for engaging a person to alert him when the receiver causes the reed to be vibrated.

A system for metering material flow made up of a member moveable in proportion to the flow of material, a permanent magnet moveable by the member and a reed switch connecting a source of energy through an electronic circuit to a counter. The circuit and reed switch are sealed in a phenolic resin, which is waterproof and enclosed in a housing that fits onto an opening in the meter housing. The circuit has a transistor with a collector connected to the counter.

An electronic remote reading system for a meter is disclosed, consisting of a permanent magnet on a shaft, rotating in proportion to volume passing through the meter. A switch, sensitive to a magnetic field, mounted on the outside of the meter in the influence of the magnetic field, a low current consumption circuit connecting the switch to a remotely located counter, powered by an energy source, such as alkaline batteries or a solar panel. The circuit is connected in such a manner that the power consumed is of such a small magnitude that the alkaline batteries have a life essentially equal to their shelf life. The solar panel is of a physical size to be mounted directly as part of the counter housing.

An eddy current separator made up of a body made of magnetic material and having a surface curved about an axis. Spaced slots in the magnetic body extend shaped like part of a hollow cylindrical body having an outer surface and an inner surface. The surfaces and electrical coils are disposed in the slots. The coils can be connected to a source of multiphase electricity forming a traveling magnetic field projection from the curved surface. The field will induce eddy current in electrically conductive material supported on the curved surface thereby, separating electrically conductive material from other material.

A means of optically recognizing the presence of substances on or within the walls of a transparent object or on the surface of a reflecting object by impinging a bar of light on the object and collecting the reflected or refracted rays of light by means of optical fibers and directing the light onto a photosensitive element connected to a circuit for using said information. The device disclosed is particularly suitable for inspecting glass jars to detect the presence of foreign material on the surface of the jars, such as "doping" or a mold release compound during manufacture, such as black spots which are undesirable because they have an unsightly appearance. The mold release is a necessary part of the jar manufacture process. The present system involves manual inspection of jars.

A method and apparatus for calibrating a transmissometer having a primary light source and a primary detector for receiving light from the light source through a gas. The apparatus includes a lens supported on a lens. The method and apparatus includes means for catching a beam of light from the primary light source and compressing the beam so that it can be transmitted by a fiber optic guide, then the beam is expanded to its original dimensions so that the normal system sensor sees the source beams at its original dimension.

A xerographic copier made up of a machine frame having a suspension mechanism supported in a cabinet so that the frame can be pulled out of the front of the cabinet for servicing. The machine has a drum covered with a removable photo-sensitive sheet of material held in place by double sided adhesive tape and a lens system made up of two lenses. The lenses are swung about an axis passing through the periphery of the drum, and the lenses are maintained at a fixed distance from the document support throughout their movement. A toner dispenser made up of magnetic rubber disposed in the form of a hollow cylinder which moves past a permanent magnet held in fixed position relative to the inner periphery of the cylinder is provided. The magnetic particles in the magnetic rubber are so magnetized that they provide a plurality of spaced magnetic poles, and the permanent magnet cooperates with these poles, causing the particles on the outer side of the hollow cylinder to erect in the form of brush bristles. The permanent magnet can be adjusted so that the brush bristles are formed at the point where the magnetic rubber passes the photoconductor surface.

A xerography type copy machine is disclosed. The machine has a photo conductor and a brush covered with a flexible sheet material for applying powdered material to the photo conductor of said xerography type machine. The flexible material contains particles of a permanently magnetized material, encapsulated in the flexible sheet. A permanent bar magnet is supported adjacent the flexible sheet on the side thereof remote from the photoconductor. The permanent magnet has a pole extending perpendicular to the direction of travel of the sheet so that when the magnetic field from the bar magnet passes through the laterally extending magnetic poles of the sheet, it alternately aids and opposes the field of the magnets on the sheet thereby causing the magnetic particles attracted to the sheet to bristle out and retract back to the sheet thereby causing the powder to form bristles which brush against the photo conductor and allow toner to be attracted to the charged parts of the photo conductor to form an image.
