Abstract: A rubber formulation with good wet traction properties includes one or more elastomers and at least two types of particulate filler materials including at least one of which has a relatively high free surface energy in water (i.e., a supplemental filler). The formulation containing the supplemental filler(s) can provide a vulcanizate that has a British pendulum (skid) number that is at least ˜5% greater than that of a vulcanizate made from an essentially identical formulation that does not contain the supplemental filler(s). Also provided is a method for providing such a formulation which involves identifying one or more supplemental fillers having relatively high free surface energies in water, replacing at least 15% (by wt.) of one or more of the conventional particulate fillers in the formulation with an approximately equivalent volume of supplemental filler particles, and providing the modified formulation.

Abstract: A method of precision assembly of component parts of an article uses a laser light projection system in combination with a photoreactive material. The photoreactive material is applied to the component parts of the article being assembled, where the photoreactive material is exposed to the laser light emitted by the projector system. When the photoreactive material is exposed to the laser light, the appearance of the material changes to mark a location on the material and thereby on the component part where an assembly operation is to take place.

Abstract: Honeycomb products and methods of manufacture thereof, particularly for aerospace applications. The honeycomb core products are made of a plastic material, such as a thermoplastic material, and preferably are made by a direct manufacturing process, such as stereo lithography, selective laser sintering, or fused deposition modeling. The cell sizes, shapes and wall thicknesses can be modified or varied throughout the product as desired. An interlocking structure is utilized to securely hold together adjacent honeycomb products.

Abstract: An ion implantation process system, including an ion implanter apparatus for carrying out an ion implantation process. A supply of source gas for the ion implantation process is arranged to flow to the ion implanter apparatus, which discharges an effluent gas stream including ionization products of the source gas during the ion implantation process. The system includes an effluent abatement apparatus for removing hazardous effluent species from the effluent gas stream. The source gas may be furnished from a low pressure gas source in which the source gas is sorptively retained in a vessel on a sorbent medium having affinity for the source gas, and desorbed for dispensing to the process system. A novel scrubbing composition may be employed for effluent treatment, and the scrubbing composition breakthrough of scrubbable component may be monitored with a device such as a quartz microbalance monitor.

Abstract: A process for polymerizing 1,3-butadiene into syndiotactic 1,2-polybutadiene is described using a catalyst system comprising (a) a chromium-containing compound, (b) an organoaluminum hydride, and (c) a hydrogen phosphite. The use of the catalyst system avoids the use of environmentally detrimental components such as carbon disulfide and halogenated solvents. The syndiotactic 1,2-polybutadiene can be used as a plastic or as an additive for rubber compositions wherein it can crosslink with conventional rubbers using conventional crosslinking agents.

Abstract: A new tool has been developed for, in one aspect, facilitating release of a tubular string coupled between a travelling block and elevators with insufficient clearance to release elevator slips in order to remove the tubular. In one aspect the releasing tool is effectively shortened permitting release of the elevators. Such shortening is effected by releasing an expansion sub and piston within the tool for relative movement with respect to other parts of the tool. Initially the expansion sub and piston are held in place by fluid in a first chamber. Movement of fluid from the first chamber and movement of fluid into a second chamber housing the piston results in piston movement (and movement of the expansion sub which is secured to the piston) to effectively shorten the tool. In one aspect the fluid moves in a closed loop between the chambers and no fluid is expelled to the environment. In another aspect only one fluid chamber is used.
