  • Publication number: 20190194558
    Abstract: Disclosed are Group III base stocks comprising greater than or equal to about 90 wt. % saturated hydrocarbons (saturates); a viscosity index from 120 to 145; a unique ratio of molecules with multi-ring naphthenes to single ring naphthenes (2R+N/1RN); a unique ratio of branched carbons to straight chain carbons (BC/SC); a unique ratio of branched carbons to terminal carbons (BC/TC); and unique MRV behavior as a function of base stock naphthene ratio (2R+N/1RN). A method for preparing the base stocks is also disclosed. Also disclosed is a lubricating oil having the base stock as a major component, and an additive as a minor component.

  • Publication number: 20190194562
    Abstract: Disclosed are Group III base stocks comprising at least 30 wt % naphthenes, a viscosity index from 120 to 145; and a unique ratio of molecules with multi-ring naphthenes to single ring naphthenes (2R+N/1RN). A method for preparing the base stocks is also disclosed. Also disclosed is a lubricating oil having the base stock as a major component, and an additive as a minor component.

  • Patent number: 4511158
    Abstract: A device for securely yet removably attaching a pole, for example, an intravenous pole of the type having wheels supporting it for movement across a surface, to a wheeled patient transport device, such as, a wheeled stretcher, wheelchair, or the like, so that the pole and the patient transport device can be moved as a contiguous unit across a surface, the device comprises a clamp member for removably clamping the intravenous pole and a member rigidly associated with a portion of the patient transport device for receiving the clamp thereby securing the intravenous pole thereto.
