Abstract: BINARY MULTIPLIER CIRCUIT INCLUDING CODING CIRCUIT Abstract of the Disclosure A binary multiplier circuit wherein the product is expressed in coded form as soon as the linear (or non-coded) product is produced.  When a twelve-bit binary number is multiplied by another twelve-bit binary number a twenty-four bit binary number is produced. The twenty-four bit product can be coded as an unsigned seven-bit binary number (µ-255 code) as follows.  The number 33 x 211 in binary form is added to the linear product to form an augmented product.  The number of leading zeroes in the augmented product is counted and the base-minus-one complement of the count is used for the three most significant bit positions of the coded product.  The four next most significant bits of the augmented product, after the most significant logic 1, are used for the four least significant bit positions of the coded product.  Suitable circuitry is described which allows the coding process, just described, to take place while the linear product is in the process of being formed, and produces the coded result when the final linear product is completed.                             - i -

Title: Water developable lithographic printing plate having dual photosensitive layering
Inventor: GOLDA EUGENE
IPC: G03F7/00
Filed: 1978-05-02
Granted: 1981-06-16
Abstract: ABSTRACT OF THE DISCLOSURE The invention is a method for producing a water developable litho-graphic printing plate which comprises treating at least one surface of a metal sheet substrate with a layer of a lithographically suitable, light sensitive, water soluble substance and subsequently coating the thus treated base sheet with an upper layer of a water-insoluble, ink receptive, litho-graphically suitable photosensitive composition.  The photosensitive layers must be either both positive working or both negative working.  The photo-sensitive composition is either water-permeable before exposure to actinic radiation and becomes water-impermeable upon exposure to actinic radiation or it is water-impermeable before exposure to actinic radiation and becomes water-permeable upon exposure to actinic radiation.  Upon imagewise exposure through a mask by standard methods the exposed areas of said upper photosensitive composition become either water-permeable or water-impermeable and the un-exposed areas remain water-impermeable or water-permeable as opposed to the exposed areas.  Upon said imagewise exposure, the exposed lower level areas in a negative system are rendered water insoluble whereas the exposed lower level areas in a positive system are rendered more water soluble than the unexposed areas.

Abstract: ABSTRACT OF THE DISCLOSURE      A nuclear reactor system wherein useful thermal energy and plutonium are produced.  A smaller, high velocity, sub-critical, downward traveling slug intercepts a larger, much slower, downward falling, sub-critical, larger target-mass.  The combined masses are more than prompt-critical and the effects of the resulting ex-plosion are contained within a large pressure vessel.  Spray of mostly molten sodium as a slurry with actinides therein protects the walls from the neutrons, photons, and blast-shock of the ex-plosion and absorbs thermal energy and debris from the explosion.     Heated slurry which contains neutron-irradiated actinides is drained from the pressure vessel to provide useful heat energy and pre-cipitated materials which with sodium, are used in the fabrication of both new slugs and target-masses.

Abstract: ABSTRACT The present invention is directed to an improved optical fiber holder assembly and method for terminating, an optical fiber with-in the terminal end of a fiber optic cable holder.  While prior art techniques have been found to be successful for terminating an opti-cal fiber, because adhesive material, such as epoxy is required for bonding the optical fiber within an optical fiber holder or terminat-ing pin, these techniques are only suited for application in laboratory or manufacturing environments having the necessary equipment for pre-paring and curing the adhesive material.  As a result, there is a need for a fiber optic connector assembly which may be utilized in a field environment.  The assembly of the present invention includes a terminal pin having a cable receiving bore extending into the pin from its rear end and a communicating terminal end bore of smaller dimension extending from the terminal pin forward terminating end. A resilient insert member having a central aperture dimensioned for receiving the optical fiber and an outer portion which is greater in dimension than the terminal end bore when the insert member is in its free uncompressed state is forced into the terminal end bore. the terminal end bore uniformly compresses the resilient insert mem-ber thereby causing the central aperture to be uniformly contracted about the optical fiber as the insert member is forced into the termi-nal end bore.

Abstract: ABSTRACT OF THE DISCLOSURE      The formation of manganese-derivative scale in equipment involved in polyester manufacture is reduced by introduction of a sterically hindered benzoic acid in approximately stoichiometric amount.  The acids include 2,6-dichloro-, 2,6-dimethyl- and 2,4,6-trimethylbenzoic acids.  The scale is believed to be insoluble manganese terephthalate, presumably formed by reaction of manganese acetate catalyst generated as a result of dimethyl terephtha-late with excess ethylene glycol.  Preferably an alkali metal salt of an organic acid, such as sodium acetate or lithium acetate is also used to give a synergistic effect in combination with the hindered acid.

Abstract: ABSTRACT OF THE DISCLOSURE     A toilet facility that is completely independent of water supply and sewer lines includes a house having a waste-receiving tank within it and another tank located outside the house.  The two tanks are connected by a transfer pipe provided with a pump for pumping the waste from the inside tank to the outside tank.  The outside tank is provided with a discharge pipe leading from it, and this pipe likewise has a pump for removing waste from the outside tank.  The dis-charge pipe for the outside tank easily connects with a collection receptacle that can be detached and disposed of.          Each tank contains an aeration pipe to which an air compressor is connected, thus enabling pressurized air to bubble through the waste in the two tanks and to activate aerobic bacteria in the waste.  Each tank also contains a heating element which normally maintains the waste in the tank at about 97°F, but has the capability of elevating the waste to a temperature above the boiling point of water so that the water may be evaporated from the waste.   The pump in the discharge line may not be energized within 48 to 96 hours of the last opera-tion of the pump in the transfer line so as to provide suffi-cient time to purify the waste in the outside tank after the last addition to that tank.  The house has a translucent dome-shaped roof provided with a gutter at its lower edge and a vent that raises and lowers at its top.  Major components of the house are formed from plastic using rotational molding techniques.

Abstract: Abstract of the Disclosure There are disclosed graft polyesters useful as adhesives and coatings and especially useful in processes for sizing spun and continuous filament synthetic organic and inorganic fibrous yarn.  One embodiment of the invention is a textile size composition having free carboxyl groups which is prepared in situ on a textile yarn by the appli-cation of neat or radiation to a mixture of an unsaturated polyester reactant and a monovinyl monomer reactant compris-ing an acidic monovinyl monomer having at least one carboxyl group or mixtures thereof with any monovinyl monomer. Desizing can be accomplished by partial neutralization of the size to a pH of at least 6 by reacting the size with a base to render the graft polyester water-dispersible or water-soluble.          The graft polyester compositions of the invention are especially useful as size compositions since they can be applied to the yarn from a solventless mixture and require only at least one of the application of heat or irradiation to graft polymerize the size in situ on the yarn.  The graft polyester of the invention comprises the reaction product of (1) an unsaturated polyester which is the reaction product of at least one polycarboxylic acid reactant, preferably a dicarboxylic acid reactant and at least one polyhydric alcohol reactant, preferably a diol, wherein a minor effec-tive proportion of at least one of said reactants is .alpha.,.beta.-ethylenically unsaturated with (2) at least one monovinyl monomer reactant comprising at least one acidic monovinyl monomer containing at least one carboxyl group or a mixture of said vinyl monomer with any monovinyl monomer.           Alternatively, where water-insolubility is desired in the graft polyester under both acid and basic conditions. a polyunsaturated vinyl monomer is utilized having two or more vinyl groups per molecule.  The graft polyesters of the invention prepared using monovinyl monomers also can be reacted with cross-linking resins, such as aminoplast resins, confer water-insolubility under both basic and acid conditions.
