Abstract: It is sometimes advantageous to disperse crystalline polymers throughout rubbery elastomers. For instance, the cold flow characteristics and green strength of polydiene rubbers can be improved by dispersing syndiotactic-1,2-polybutadiene therein. This invention discloses a process for preparing a highly dispersed blend of a crystalline polymer in a rubbery elastomer which comprises (1) polymerizing at least one diene monomer in an organic solvent under solution polymerization conditions to form a polymer cement of the rubbery elastomer in the organic solvent, (2) polymerizing additional monomers in the polymer cement into the crystalline polymer to form a rubbery cement having the crystalline polymer dispersed therein, and (3) recovering the highly dispersed blend of the crystalline polymer in the rubbery elastomer from the organic solvent in the rubber cement.

Abstract: In a communication network for communication between a plurality of nodes over a multi-channel communication medium, the network comprising a plurality of allocatable channels for data communication between nodes and a control channel for allocating the allocatable channels to individual nodes.  At least one of the channels operates under a token-passing protocol with a limited message packet length whereby selected messages may be set between nodes with a predetermined maximum delay.  The token-passing channel may be a control channel, and the message packets transmitted by the nodes over the control channel may comprise messages for negotiating the allocation of the allocatable channels to the individual nodes.  Alternatively, or additionally, message packets comprising data messages unconnected with negotiating the allocation of the allocatable channels may be sent over such a token-passing channel.          More than two nodes may be permitted to communicate on one of the allocatable channels, thereby establishing a logical sub-network which can operate using any desired protocol over the allocated channel.

Abstract: Abstract A method for fabricating an internal combustion engine cylinder head, comprises the steps: (a) forming a cast cylinder head with a passage having implanted in the walls of such passage a valve stem guide sleeve insert and a valve seat insert, the inserts being formed of fused powder metal and each having an internal cylindrical surface prepared to near net shape no longer requiring macroscale sizing; and (b) microsizing both of the internal cylindrical surfaces by a single pass of a common rotary abrasive tool inflexible along its axis and supported for accurate alignment independent of the guide sleeve.  The cylinder head may be first formed with such passage having a recess for a valve seat insert and a guide bore for a guide sleeve; preshaped inserts are then press-fit into such recess and guide bore.  Near net shape means an oversize tolerance of plus .002-.003 inches; macroscale means measurements in increments or units greater than .01 inches.

Title: Composite gem stone and production method
Inventor: CARBONE SANTO
IPC: B44C5/06
Filed: 1989-09-29
Granted: 1991-03-26
Abstract: Abstract Composite or assembled gemstones are usually made by laminating together several layers of rock or mineral substances. Established lapidary processes used in making these stones are very effective when the gem-material part of the composite stone is of stable composition. Such material can then be easily cut and ground into the smooth flat layers necessary for laminating. These same methods, however, prove much less effective when applied to poorly-consolidated gem material: material that because of its friable nature tends to chip and flake when attempts are made to cut it into layers. My process is designed specifically for use on this latter type of gem material and is especially suited to processing gem-quality fossil ammonite shell. This process differs from the traditional methods in that it eliminates the need for cutting and grinding the gem material into smooth, flat layers. Instead, the gem material is simply shredded or fragmented into a mass of small, thin flakes. These flakes are then sprinkled on to pre-finished, crystal clear, adhesive covered bases and are overlain by another sprinkling of a dark granular substance. The composite stone is ready for use when the adhesive sets.

Abstract: A liquid sampling, metering and transfer valve assembly for providing plural dilutions of a single liquid sample and comprising a pair of outer stationary elements sandwiching a rotatable element.  The rotatable element carries precise volume segmenting passageways.  The outer elements carry counterpart passageways for communicating to the exterior of the valve assembly, one outer element carrying loops each for metering and storing a precise volume of diluent and the other valve elements carrying through passageways for communicating to and from said respective loops.  A continuous body of sample is introduced into the valve assembly along a path through a pair of the segmenting passageways and a pair of measured portions (aliquots) are isolated from said path.  The rotatable element is operated to direct one aliquot along with the content of one loop to an exterior location for mixing.  The other sample aliquot is retained.  The thus formed mixture is reintroduced into the valve assembly along a path through the third segmenting passageway and an aliquot thereof is isolated.  Both it and the retained sample aliquot then are directed from the valve assembly to respective testing locations along with the respective content of the remaining loops. Channels are provided in the inner faces of the outer elements and communicatively coupled.  Entry and outlet ports enable cleaning reagent to be introduced therhein, the sandwiched element being rotated 360 degrees whereby to rinse the facing interior surfaces of the valve assembly.
