Title: Production of hydrocracked lubricants
Inventor: APELIAN MINAS ROBERT
IPC: B01J29/04
Filed: 1992-07-23
Granted: 2004-02-24
Abstract: A process for producing high quality lubricants by hydrocracking a high boiling hydrocarbon feed in the presence of hydrogen and a bifunctional hydrocracking catalyst based on an ultra-large pore crystalline material. The crystalline material exhibits unusually large pores of at least 13 .ANG. diameter and a high sorption capacity demonstrated by its benzene adsorption capacity of greater than 15 grams benzene/100 grams at 6.7 kPa (50 Torr) and 25 °C. The crystalline material is characterized by an X-ray diffraction pattern with at least one d-spacing greater than 18 .ANG. and in a particularly preferred form, a hexagonal arrangement of pores of at least 13 .ANG. diameter which can be indexed with a d100 value greater ban 18 .ANG.. The hydrocracking catalysts based on these materials are capable of producing hydrocracked lobe products of good viscosity index in high yields without the use of fluorine or other promoters. Petroleum waxes may be used as the feed end is hydrocracked and hydroisomerized to form the lube products.

Title: Surface and near surface hardened medical implants
Inventor: DAVIDSON JAMES A
IPC: A61L27/06
Filed: 1994-08-16
Granted: 2005-12-06
Abstract: Surface and near surface hardened medical implants are provided. These implants are fabricated from titanium alloys that contain an amount of zirconium sufficient to permit the formation of a significant amount of zirconium oxide at the surface of the implant to cause surface hardening. Further, the zirconium-containing titanium alloy implants are characterized in having an alloy core with an oxygen-rich layer surrounding the core, and a surface layer, overlying the oxygen-rich layer, including mixed oxides of the metals present in the alloy. A zirconium-rich interface may sometimes be present between the oxygen-rich layer and the mixed-oxide surface layer. The method of producing these surface hardened implants includes the steps of heating the implant in an oxygen containing environment at a temperature sufficient to allow oxygen to diffuse to and react with the implant surface and near surface.

Abstract: A refrigeration/heat pump system comprises a compressor, condenser, evaporator and expansion valve all of which are mounted within a rectangular housing for convenient layout and accessibility. The condenser, evaporator and expansion valve are all oversized relative to the compressor so as to obtain modifications in the operating parameters and particularly a compression ratio of the compressor which is less than 4.5:1. This mismatch of the components surprisingly provides an enhanced efficiency of operations in tons/hp. The components are arranged in the housing with the compressor centrally of the housing, the evaporator along one side, the condenser along the opposed side and with the system connections in the rear wall. The electrical components are provided in a vertical compartment on one side of the front wall which can be accessed by an opening door. A removable panel in the front wall and in the rear wall allows access to the components.
