Abstract: This invention relates to the use of colloids of a core of zinc containing compounds and a shell of metal containing surfactants, such as salicylates and or sulfonates, metal alkanoates, and or metal carboxylates, as additives in lubricant compositions having good anti-wear properties, especially for engine crankcase applications.

Abstract: An administration set is configured to couple to a control module of a peristaltic infusion pump. The set can include a pressure plate and a peristaltic tube. The pressure plate can have attachment features structured to mate with corresponding attachment features of the control module such that the pressure plate is maintained in a fixed position relative to the control module. The peristaltic tube can include a first portion having first inner and outer diameters, a second portion downstream of the first portion having second inner and outer diameters, and a transition portion between the first and second portions. The peristaltic tube can be located along the pressure plate and positioned such that when the attachment features of the pressure plate and control module are mated, an expulsor of the control module engages the first portion and an air-in-line detector of the control module engages the second portion.

Abstract: An intake manifold system including an intake manifold and a compressed natural gas (CNG) fuel injector located between an inlet and an outlet of the intake manifold. The CNG fuel injector includes a housing, an inlet, an outlet, a seat, a closure member, and a nozzle. In a preferred embodiment, the inlet and outlet communicate a flow of gaseous fuel regulated by the closure member. The gaseous fuel passes through the seat, which is secured to a rim surface of a retainer portion of the nozzle, and into a flow passage that further communicates the flow of gaseous fuel into one or more flow channels. The orientation of the flow channels within the nozzle greatly affects the discharge pattern and mixing characteristics of the gaseous fuel within an intake manifold. A method of metering gaseous fuel in an intake manifold having a gaseous fuel supply coupled to a fuel injector is also described.

Abstract: A method of making an electrically-operated fluid valve for improving the metal-to-metal sealing of the valve needle to the valve seat, particularly of the rounded tip end of the needle to a frusto-conical depression in the seat. The method comprises applying a controlled axial compressive load to the seated needle to cause the annular zone of sealing contact between the needle and the seat to be coined.
