Abstract: Embodiments herein relate to systems and methods for varnish detection and/or monitoring in hydrocarbon fluids. In various embodiments, a system for monitoring varnish compounds in fluids is included herein including a control circuit in communication with a fluid property sensor. The system can measure one or more fluid properties (such as dielectric constant, density, resistivity, viscosity and the like) with the fluid property sensor, monitor the same over a time period, and identify an occurrence of a rate of change in the measured property indicating a presence of the varnish compounds. In various embodiments, a system herein can be configured to measure a fluid property of a fluid with a fluid property sensor, monitor the fluid property value over a time period, and predict a time of the onset of varnish compound formation based on the trend of the fluid property value over time. Other embodiments are also included herein.

Abstract: An additional part for a hand-held device for electrically assisted skin treatment includes a ring which is clippable onto the hand-held device. The additional part further includes an absorbent carrier material where the absorbent carrier material is soaked with an active ingredient and where the absorbent carrier material is fastened to the ring.

Abstract: A hand-held device for electrically assisted skin treatment includes a skin electrode and a hand electrode. An absorbent carrier material is soaked with an active ingredient. The absorbent carrier material is fastened to a ring and the ring is clippable onto the hand-held device. The absorbent carrier material extends over the skin electrode when the ring is in a clipped-on state with respect to the hand-held device.

Abstract: A liquid hydrocarbon filterability system includes a liquid hydrocarbon sample source piping in fluid communication with a liquid hydrocarbon sample container. A filtration media element is in fluid communication with the liquid hydrocarbon sample source piping. Filtered liquid hydrocarbon outlet piping is in fluid communication with and downstream of the filtration media element. A flow or volume measurement element is in fluid communication with the filtered liquid hydrocarbon outlet piping and is configured to measure an amount of liquid hydrocarbon passing through the filtration media element. A constant pressure source is configured to provide liquid hydrocarbon to the filtration media element at a constant pressure.

Abstract: The invention relates to a hand-held device for electrically powered skin treatment, whereby current is passed into the skin from an external electric circuit via an electrode (20) so that active ingredients of a cream applied earlier to the skin can better penetrate into the skin. To aid this effect, a cap (9) of the device, which functions as an electrode (20), is provided with a vibrator (15) so that the electrode (20) vibrates on the skin, thus working the cream into the skin.

Abstract: A method and system of conditioning human skin and hair using a hand-held skin/hair conditioner having interchangeable interface conductors that are contoured to enhance electrical conductivity between the conditioner and a variety of body areas. Each of the interchangeable interface conductors are preferably formed to maximize surface area contact with a variety of body surfaces such as scalp/hair, body skin, and facial skin. In a preferred embodiment, the skin/hair conditioner is formed to fit comfortably and controllably in a user's grasp while providing maximum contact with the selected body surface. The skin/hair conditioner includes an audio signal generator and a vibration mechanism to alert a user of a change in status of the conditioner. The interface conductors may be (1) smoothly rounded, (2) include teeth, (3) spherical or hemispherical (4) include multiple rounded nodules.
