Abstract: Inert gas blanket protects oxidatively labile substance from oxidation. For example, fuels and lubricants such as present in fuel tanks, bearings, crankcases, gear boxes, transmissions, and so forth, employed in or in conjunction with internal combustion, jet and turbine engines, or a combustible substance such as flour dust in a grain silo, can be protected with a nitrogen blanket provided from the separation of air with a membrane containing device. Useful life of oleaginous liquids and hydrocarbon-based lubricants can be extended. For example, with the practice of the present invention, it may be necessary to change automobile engine oil only after twenty to fifty thousand miles of use.

Abstract: Physical property of a liquid sample to include a viscometric and/or rheological property if not a structural property such as gelation and/or crystallization can be determined with a rotating viscometer employed in a Scanning Brookfield technique. The viscometer and technique employ a Brookfield-type head having a high torque capacity. Low temperatures may be employed in the scan. For example, properties of a motor oil having a very high viscosity and/or a gelation point owing to its intrinsic properties, oxidation and/or sooting and so on, can be accurately, precisely, rapidly, and repeatably determined.

Abstract: Device for precise replacement of liquid has boundaries for one incoming liquid or more and one exiting liquid or more, and one pressure-transmitting barrier or more. The device may be augmented by a makeup contrivance or be for makeup alone. The device can include or be provided with one or more of the following: multiple units of the device; delivery of multiple, separate liquids; various rates of replacement; topping up of expended liquids and/or their additives; use of vacuum force from operation of the mechanism to induce replacement; and/or use of pneumatic, hydraulic and/or mechanical actuated force to induce replacement. Examples of pressure-transmitting barriers are a simple piston; a multi-part, expansible piston; one diaphragm or more; one flexible bag or more; and combinations thereof. Liquid can be replaced during normal operation of the mechanism.

Abstract: Thin film thermal oxidative engine oil or other oleaginous liquid deposit device has an oleaginous test liquid placement volume; a heatable depositor surface in liquid communication with the volume; a supply for at least one of an oxidant and another substance which can adversely affect the test liquid; and a relatively thin film forming unit which delivers the test liquid to the depositor surface in a relatively thin film. Thin film thermal oxidative engine oil or other oleaginous fluid deposit method is also provided, which includes providing an oleaginous test liquid in an oleaginous test liquid placement volume; providing a depositor surface and heating said surface; delivering the test liquid as a relatively thin film to the heated depositor surface; providing to the test liquid an oxidizing and/or other substance which can adversely affect the test liquid; and observing any deposits or other activity thereabout. The invention is useful in oil testing.

Abstract: Low heat-transmissible spindle for rotary viscometry includes an elongate, radially balanced, straight shaft made of a suitably stiff material having a low heat-transmission value, with a head monolithic with the shaft which can contact and interface with a test fluid to yield drag from the contact and interface when the spindle is rotated in the fluid; and a spindle coupling nut attached to the shaft opposite the head. For example, the shaft may be made of a woven glass fabric cylinder laminated with a synthetic resin, and the head made of stainless steel. A rotary viscometer can be equipped with the spindle, and fluid viscosity can be determined by employing the same in a rotary viscometric protocol, for example, ASTM D 2983.

Abstract: A method to condense or coalesce matter is carried out by providing a suitable, narrow passageway for throughput of matter in a vapor state, and passing the matter in a vapor state through said passageway, under conditions such that the matter is coalesced into a more ordered state. Also, a matter coalescing apparatus has a hollow housing in communication with at least one of--(A) a plurality of suitably narrow hollow passageways and (B) a suitably narrow, elongately hollow, matter-coalescing passageway--for throughput of matter to include as a vapor therein. Consequently, highly efficient yields of coalesced matter, to include liquid coalesced from vapor, even under only mild vacuum or at about ambient atmospheric pressure can be obtained. This is especially so with respect to oils, where yields as high as 95 percent or greater can be provided hereby. The invention can be practiced under such outstanding yield efficiencies without a general need for significant external cooling.

A volume for containing coolant material is provided for cooling the oven volume is provided apart from the oven volume, and the cooling volume is adapted to contain cooling material, at least during operation of the cooling cycle. Optionally, the cooling volume can be closed off from the oven volume when the device is in heating mode and opened when in cooling mode, but preferably, it is not but has a drainable liquid, for example, water, cooling system installed in the cooling volume. The device may have an air plume; preferably however, it has such a plume eliminated with high circulation blowing and mixing of the bath gas, for example, air, provided. Accessories such as a removable drain tray, and so forth, may be added.

Abstract: Negligible pressure drop absorber has a hollow housing having an entrance opening and an exit opening, and an absorber unit including a plurality of layers of an absorbent material arranged substantially parallel with one another to form a passageway for a gaseous stream, through which the gaseous stream is adapted to travel and by which gaseous liquid and liquid droplets are absorbed from the gaseous stream with a negligible drop in pressure. In particular, in the testing of engine oils with a Noack-type teat device, added collection by absorbing drawn over sample is accomplished, with the ability to evaluate that sample, and without incurring a pressure drop in the system adverse thereto.
