Abstract: OXYGEN SCAVENGING SYSTEM FOR ANAEROBIOSIS            ABSTRACT OF THE DISCLOSURE     A self-contained system is provided for producing an oxygen-free environment for anaerobiosis and cul-turing wherein the system possesses the ability to pro-vide and maintain the oxygen-free environment, even after the opening and closing of the sealed container therefore several times.  The system includes a metal-lic couple, preferably copper-magnesium, which reacts with water to induce and maintain the oxygen-free en-vironment.  The degree of addition of water to the sys-tem controls the rate of reduction of the environment. The system possesses a dual oxygen scavenging function by the controlled addition of water.  That is, if a small amount of moisture is added to the system couple of the invention, hydrogen is liberated, which causes a drying in the system simultaneously with a reaction of a portion of the couple to gradually scavenge oxy-gen from the environment, simultaneously with the liber-ation of hydrogen.  If desired, in such an arrangement the subsequent addition of water generates hydrogen again until all the magnesium is used up, in order to provide a subsequent oxygen scavenging property. In addition, the system includes a sealable petri dish so conformed to include means for maintaining the sys-tem of the invention in combination with an indicator for anaerobiosis, a catalyst for the system, a carbon dioxide generator, and space for the culture media.

Abstract: Abstract of the Disclosure A novel liquid composition for developing latent electrostatic images whereby to form a gap between the developed image and the carrier sheet to which the developed image is to be transferred.  The composition is such that it contains both charged and uncharged spacer particles.          The spacer particles are of larger diameter than the toner particles so as to form a gap between the developed image and the carrier sheet to which they are transferred.  The spacer particles, furthermore, have a specific gravity lower than the specific gravity of the carrier liquid, which may be a low-boiling hydrocarbon.  This is accomplished by having a gas bubble enclosed in a portion of the material of which the spacer particles are formed, which material is preferably glass.  The charged spacer particles may be coated with a polymer of which the toner particles are formed.          Both the coated spacer particles and the toner particles bear the same charge.  The remainder of the spacer particles are substantially uncharged.  The uncharged spacer particles will remain on the background areas of the developed  image and prevent the carrier sheet from absorbing liquid present in the developing composition.  The charged spacer particles will go to the image areas and become agglomerated with the toner.

At both of its ends, the cable has squared drive keys in sliding-driving engagement with the motor and applicator shafts.  The motor shaft has an outer bore, and a con-nector extension fits around the motor shaft and projects outwardly therefrom.  The connector has a square bore which receives a cable drive key that slides within the connector, and within and beyond the end of the motor shaft, to accommodate tension and compression exerted upon the cable yet remains in driving engagement with the motor shaft.  At the applicator, the second cable drive key slides within a square bore and also a larger bore in the applicator drive shaft but remains in driving engagement with the shaft.  Swivel couplings are provided at both ends of a sheath that surrounds the cable.  At the power unit the sheath is fitted with a-first ferrule having a cylindrical flange that is secured by a cylindrical nut to a bell sleeve attached to the applicator, the second sheath end fits with a second ferrule having a circular flange secured by a nut within the applicator for swivel movement relative thereto.  A high strength bearing of stronger material than the rest of the applicator is provided near the eccentric, and the applicator has watertight seals. The unitary structure of the applicator provides a passageway for the eccentric drive shaft and for hold-ing the second ferrule.  The power unit has a carrying handle which receives and releasably locks the appli-cator so that a single hand can grasp and carry both the power unit handle and the applicator.  The rear of the applicator has textile latching material secured to it which locks with the side surface of a textile belt so that the belt can hold the applicator against a selected part of the body.

Abstract: ABSTRACT OF THE DISCLOSURE       A blind fastener assembly is disclosed, which is suitable for use in joint assemblies including advanced composite materials.  The fastener assembly includes a pin, an expander, a sleeve, and an expandable washer, each of which have an initial diameter which permit them to pass through a hole in the workpiece.  The washer is mounted about the pin shank between the sleeve and a tapered nose portion of the expander.  The fastener assembly is inserted in a hole in the workpiece so that the expander head abuts the workpiece.  Rotation of the pin causes the sleeve to force the washer to slide over the tapered  nose portion of the expander causing it to expand and abut the blind side of the workpiece.  In one embodiment of the invention the pin threadably engages the expander and the head of the pin is positioned on the blind side of the workpiece.  The washer is initially seated in a groove in the pin shank.  Rotation of the pin causes its head and the sleeve to advance toward the workpiece, and the washer is forced from the groove by the sleeve causing it to partially expand.  Expansion is completed when the sleeve forces the washer over the tapered nose portion of the expander,  In another embodiment the pin head is positioned on the accessible side of the workpiece and the pin threadably engages the sleeve.  The washer is mounted about the pin on an extended portion of the expander which extends from the nose position.  Rotation of the pin causes the sleeve to advance toward the workpiece forcing the washer over the tapered nose portion of the expander until it is fully expanded and abuts the workpiece.
