Abstract: An apparatus, system and process for continuously fractionating blood in which blood from a donor is passed along a semipermeable membrane through which passes a fraction to be collected. Turbulent blood flow is maintained to prevent a filter cake from building up on the membrane surface and thereby prevent the blood fraction from passing therethrough. The system includes the blood fractionator, a collection apparatus, a blood pump and appropriate blood clot filters. The rapid blood fraction production rate and the small size of the device facilitates in situ collection of the blood fraction. Fractionation rates upwards of 30 volume percent of blood flow are possible.

Abstract: A photoelectric smoke detector includes a light source and a light responsive cell and a smoke chamber therebetween all located within a generally cylindrical inner housing which is in turn concentrically located within a generally cylindrical outer housing. The inside surface of the outer housing is reflective, but the inner housing normally prevents light emitted by the light source into the smoke chamber from striking the outer housing. The inner housing contains one or more windows and is rotatable to move the windows to a position wherein light from the source can pass therethrough to the reflective surface of the outer housing and be reflected thereby back to the light responsive cell. The amount of light striking the reflective surface can be continuously adjusted between a normal condition when no light is reflected and a full test condition when a maximum quantity of light is reflected to the light responsive cell.

Abstract: The apparatus comprises a luminosity probe to provide an electrical signal in response to the combustion event in a diesel engine and also comprises a probe to provide another electrical signal indicative of top dead center. Both electrical signals are processed and applied to a circuit which generates an output pulse having a duration corresponding to the time between the start of the electrical signals. A meter displays the angle represented by the duration of such pulse. Circuitry is provided to compensate for offset.

Abstract: Predetermined diffusing elements such as chromium and/or aluminum are diffused into the surface of a ferrous-based part while preventing, or at least minimizing, bonding of portions of such part to each other or to a fixture with which the part is processed, by constructing the fixture of a barrier material or placing a barrier layer between the member and the part. The barrier has a composition to substantially preclude diffusion therein of the predetermined element and that is capable of withstanding a molten-lead alloy bath. Then the part is contacted by a molten alloy bath consisting essentially of lead and the diffusing elements. Thereafter, the part is separated from the member. The process finds particular use when the part is coiled sheet steel, in which case adjacent flights of coil are spaced by separator means which is made of a barrier material or carries a barrier layer.

Abstract: A floating roof storage tank having an upstanding tank shell for containing liquid to be stored and having therein a floating roof floating on the surface of the stored liquid, a primary seal interconnecting the floating roof and the tank shell, and an annular secondary seal extending between the floating roof and the tank shell providing a gas tight seal and weather shield for the primary seal, sealant is used at the inner end of the secondary seal mounted to the floating tank to ensure the gas tight connection thereat, and a tapered and rounded flexible free or outer end of the secondary seal ensures that irregularities in the tank shell do not permit vapors to escape; support structures maintain the secondary seal in its desired configuration and a variety of structures are disclosed for maintaining adjacent arcuate sections of the secondary seal in fixed and sealed relation.

Abstract: There is disclosed a transducer to sense the vacuum in the intake manifold of an engine or other chamber. The electrical signal it produces is converted into digital signals for operating a liquid crystal display. The output of the transducer is also coupled to a driver which is operable in one mode to produce energizing currents on all of its outputs corresponding to the amplitude of the electrical signal. The driver is coupled to LEDs which are thus illuminated. The driver is also operated in a second mode so that only one of the outputs is energized and in that mode the driver receives only the AC component of the transducer output.

Abstract: In a dry seal gasholder cylindrical storage tank with a vertically-movable piston, an improved piston leveling system includes a vertically-movable weight outside the tank and connected by equal-length cables to spaced-apart support points on the piston at different distances from the weight. An array of guide sheaves on the tank define equal-length cable paths. The cables are pivotally coupled to spaced-apart points on a coupling plate to which a pair of attachment plates on the weight are also pivotally connected. Apertures in the attachment plates and the coupling plate are disposable in registry with one another for receiving a pin therethrough when the cable attachment points are in horizontal alignment, thereby to indicate equal tension in the cables.

Abstract: A thrust producing shoe sole and heel having fluid-proof cavities located in the heel portion and in the sole portion which underlies the metatarsal ball area of a foot for which the sole and heel is sized, the cavities being connected by restricted passageways. The material underlying the cavities at the bottom of the sole and heel is resilient and wear-resistant. Fluid is contained within the cavities and passageways in such pressure and amount as to cause bulges below the normal bottoms of the sole and heel, whereby at rest a foot on the sole and heel is cushioned comfortably on the fluid in the bulges, and in walking and running, fluid under bulge producing pressure alternates through the passageways between the cavities, producing shock absorption and an alternate lifting effect by the sole and heel bulges which provides forward thrust both in the heel portion and in the metatarsal ball area that facilitates walking and running.
