  • Patent number: 4578215
    Abstract: A material for enhancing the conductivity and protecting electrical contacts, the material having two basic components. The first basic component normally serves to limit corrosion between the contacts and to suspend and suitably distribute the second, or conductive component. This first component, or carrier medium, may be one or more of the following: rosin-derived hard resin, petroleum jelly, petroleum wax and a benzyl phthalate plasticizer for limiting corrosion, effecting adhesion of the material to electrical contacts, and providing body to the material for distributing the conductive component. The second component is an electrically conductive, particulate component such as, for example, metallic silver which enhances the conductivity and actively reduces the resistance by supplying multiple, parallel conductive paths for electrical current flow, filling in surface irregularities in the contacts, and penetrating surface films. The conductive component may be in powder, coarse pigment, or flake form.

  • Patent number: 4576170
    Abstract: A heart monitor and defibrillator device, which can be worn by high risk patients with only minimal interference with normal daily activities, in which one pocket-size unit contains a heart monitor and microprocessor and a second pocket-size unit contains defibrillation circuitry. ECG electrodes are attached to the patient to sense heart impulses and transmit the impulses to the first unit, which analyzes the heart beat and determines if defibrillation is required. The second unit administers the defibrillating shock when required and has a built-in delay so that the wearer is warned to prepare for defibrillation. Several defibrillation shocks may be administered at spaced intervals. The defibrillation electrodes include layers of electrically conductive, skin adhering paint having low contact resistance, and the electrodes may be moved by the patient to prevent skin irritation in the electrode site.

  • Patent number: 4575265
    Abstract: A seal for a bearing having a housing with an opening therein for receiving a shaft in which a bearing assembly is mounted in the housing and has an inner race for receiving the shaft. A seal consisting of a ring having a radially extending, outwardly facing flat surface is disposed in the housing opening adjacent the inner race, and a seal which may be of the V-ring type is mounted on the inner race and has a lip which seats on and rubs against the radial surface of the ring. Collars may be used on the race to retain the lipped seal in proper relationship with the ring on the inner race. The relationship of the lip to the metal ring is such that the bearing assembly can be purged by the outward flowing of the lubricant yet protected from the ingress of foreign matter. In some modifications, an auxiliary seal, which is disposed externally with respect to the lipped seal, may be used.

  • Patent number: 4568453
    Abstract: Apparatus and method for removing dust from particulate material, utilizing a tower or column having a passage with a series of baffles on opposite sides over which the particulate material cascades while air is drawn across the flow path of the material to remove the dust dispersed in the material and adhering to the surface of the particles of material. Air is drawn across the passage from one side to the other by vacuum or suction from a vacuum pump or the like. In performing the method using the apparatus, the particulate material is introduced at the top of the column and permitted to cascade down through the vertical passage therein from one baffle to the next, and air is drawn inwardly between the baffles on one side and outwardly between the baffles on the opposite side of the column, and, as the air flows through the material cascading between the baffles, it removes the dust from the material.

  • Patent number: 4567693
    Abstract: An instrument for sharpening microtome knives and similar articles, having a honing mechanism and a deburring or stropping mechanism, arranged on a housing which encloses motors for driving the mechanisms. The knife is honed against a stone, which is mounted on a reciprocating carriage that has a variable speed control, and the honed knife blade is then deburred or stropped using a pair of counter-rotating disks, one for each side of the knife blade. A vise securely holds the knife and positions it at the proper angle for optimum honing, and the vise is mounted in a track which allows the knife blade to be moved back and forth across the reciprocating hone for uniform honing. A shield guards against inadvertent contact with the dangerously sharp blades during the honing operation, and guards are used to prevent the vise from leaving the track.
