Title: Capped polydienes
Inventor: HALASA ADEL FARHAN
IPC: C08C19/44
Filed: 1988-09-30
Granted: 1999-03-30
Abstract: Polydiene rubbers are commonly compounded with carbon black in making a wide variety of rubber articles including tires, hoses and belts.  It is generally desirable for the carbon black to be well dispersed throughout the polydiene in order to attain optimal physical properties.  For instance, the traction and rolling resistance of tires which are made utilizing such rubbers can be improved by better dispersing the carbon black throughout the polydiene. The subject invention discloses a technique for capping polydienes in order to improve their affinity for carbon black.  The present invention more specifically reveals a process for preparing a polydiene having a high level of affinity for carbon black which comprises reacting a metal terminated polydiene with a capping agent selected from the group consisting of (a) halogenated nitriles having the structural formula X-A-C-N wherein X represents a halogen atom and wherein A represents an alkylene group containing from 1 to 20 carbon atoms, (b) heterocyclic aromatic nitrogen containing compounds, and (c) alkyl benzoates.  Both ends of polydiene chains can be capped with polar groups by utilizing functionalized initiators, such as lithium amides.

Title: Handle operated wire puller
Inventor: PATTERSON ROBERT D JR
IPC: E21C29/16
Filed: 1988-11-22
Granted: 1991-03-19
Abstract: Abstract of the Invention A lightweight, portable device for pulling a plurality of relatively small wires through a conduit by the use of a rope attached thereto, without using a winch or necessitating the use of external power.  This device comprises an elongate frame particularly adapted for use in a substantially upright position and having lower and upper ends, with a pivotally mounted operating lever operatively located adjacent a middle portion of the frame.  At least one force-reacting component is utilized on the frame, over which the rope used with the device passes, for changing the direction of pull of the rope.  Importantly, rope clamping means are utilized on the operating lever for releasably grasping successive portions of the rope during the pulling process, and the operating lever is movable by one or more operators about its pivot point from a position in which it resides in a plane substantially parallel to and closely adjacent the plane of said elongate frame, to a position in which it resides at approximately right angles to the plane of the frame.  Each such movement of the operating lever serves to cause several feet of rope to move with respect to the force-reacting component that serves to change the pull direction of the rope, and thus to cause the plurality of wires attached to the rope to move along the conduit for a like distance.

Title: Mold and support zone for continuous casting
Inventor: PORAN MICHAEL
IPC: B22D11/04
Filed: 1988-12-02
Granted: 1993-04-20
Abstract: ABSTRACT           An apparatus for the continuous casting of slabs has a mold and a slab support zone immediately following the mold.  The mold is made up of four separate plates which are held together to define a mold cavity.  A dividing wall can be removably mounted in the mold cavity in order to divide the same into a pair of parallel casting passages.  Insertion of the dividing wall in the mold cavity makes it possible to simultaneously cast two relatively narrow slabs rather than a single wide slab.  A partition designed to constitute an extension of the dividing wall is provided for the support zone and can be removably mounted in the same.  Both the dividing wall and the partition are carried by a clamping mechanism which serves to clamp the dividing wall in the mold cavity.  The clamping mechanism, which is designed to be mounted on the mold externally of the mold cavity, may be in the form of a frame which circumscribes the mold or may consist of two discrete clamping devices one of which carries the dividing wall and the other of which carries the partition.  In the latter case, the clamping device with the partition is mounted at the end of the mold nearest the support zone while the clamping device with the dividing wall is mounted at the opposite end of the mold.  The dividing wall has one or more cooling ducts and the clamping mechanism is formed with one or more passages which communicate with the ducts and can be connected to a source of cooling fluid.  The partition is provided with spray nozzles for slab cooling and the clamping mechanism is further provided with at least one additional passage for establishing communication between the nozzles and a cooling fluid source.
