Abstract: The hydrogenation activity of a heteroatom removal catalyst, having activity for both heteroatom removal and hydrogenation, is selectively suppressed by a treatment which comprises contacting the catalyst with (i) hydrogen, (ii) a selectively deactivating agent that suppresses the catalyst's hydrogenation activity, and (iii) a protective agent, such as CO, that preserves and protects the heteroatom removal activity during the treatment. This may be achieved in a reactor while it is on-line and removing heteroatoms from a hydrocarbon feed.

Abstract: The hydrodesulfurization of a hydrocarbon feedstock contains an olefinic component achieved with increased selectivity for hydrodesulfurization by contacting the feedstock and hydrogen under hydrodesulfurization conditions with a sulfided catalyst comprising: (i) at least one non-noble metal of Group VIII; (ii) at least one metal of Group VIB; and (iii) at least one metal of Group IB, IIB and IVA, on an inorganic oxide support.

Abstract: A handheld CZT radiation detector having a CZT gamma-ray sensor, a multichannel analyzer, a fuzzy-logic component, and a display component is disclosed. The CZT gamma-ray sensor may be a coplanar grid CZT gamma-ray sensor, which provides high-quality gamma-ray analysis at a wide range of operating temperatures. The multichannel analyzer categorizes pulses produce by the CZT gamma-ray sensor into channels (discrete energy levels), resulting in pulse height data. The fuzzy-logic component analyzes the pulse height data and produces a ranked listing of radioisotopes. The fuzzy-logic component is flexible and well-suited to in-field analysis of radioisotopes. The display component may be a personal data assistant, which provides a user-friendly method of interacting with the detector. In addition, the radiation detector may be equipped with a neutron sensor to provide an enhanced mechanism of sensing radioactive materials.

Abstract: A coke oven door for placement against a door jamb of a coke oven comprises a segmented door body and plurality of toggle mechanisms coupled to the door at the juncture of each segment. The toggle mechanisms include inner and outer toggle links pivotally connected by an intermediate pivot shaft and the links are pivotable between an extended length and a shortened length. Inner ends of the toggle mechanism are coupled to the segmented door body and outer ends of the toggle mechanisms are coupled to a flexible latch tension bar. The latch tension bar engages latch hooks connected to the door jamb and vertical movement of a latch actuator rod coupled to the intermediate pivot shaft moves the toggle mechanisms to an extended position to flex the latch tension bars and force the door body against the door jamb to seal the coke oven.

Abstract: A golf club head is disclosed having a body including a striking face and a sole, the sole having a generally double-convex profile defining separate convex bounce surfaces. These convex bounce surfaces provide for decreased frictional drag induced between the ground and the sole of the club head during a typical golf club swing. In a further embodiment, the body of the golf club head includes therein a cavity opposed to the striking face, the cavity opening away from the sole. The cavity of this embodiment is relatively shallow, as the body of the club head is truncated such that only a generally planar region of the body extends therefrom. This planar region includes a portion of the striking face. Accordingly, to this form of the present invention, a club head is provided having optimal weight-balancing and performance characteristics.
