An improved hair extension having snap-lock attaching clips useful for instantly attaching or detaching the hair extension or track to the wearer's natural hair. The hair extension comprises 2 to 3 layers of human or synthetic hair tracks sewn together to create one thicker layer and 3 snap-lock clips, all sewn onto the base of the lead extension along the top inside edge. The wearer can quickly and easily apply the extension to their natural hair with the confidence of a firm and secure grip and enjoy the appearance of fuller, longer, more natural looking hair, while maintaining a completely unnoticeable appearance to the on-looker.

Disclosed is a portable charger adapted for use with wireless devices.

The current charge is delivered by a power source located within an attractive housing. A light emitting diode coupled to the integrated circuit indicates whether the wireless device is actively being charged.

An x-ray target pedestal assembly and a method of protecting the x-ray target from breaking down as a result of the extreme heat that is produced when an electron beam is aimed at the target to produce x-rays. The target is submerged in cooling fluid and is rotated by a constant flow of the cooling fluid over and around the target in order to dissipate heat. The fluid is guided by integrated flow diverters in the target cover. The target may also be protectively coated either in its entirety or along the electron beam path in order to further protect it from the heat of the electron beam impact or from breakdown as a result of attack of free radicals or other chemically reactive components of the cooling fluid which are produced in the extreme target environment.

A contaminant pressure responsive, lubricant pressure amplified or modified rotary seal cartridge for rotary well pumps and other rotary mechanisms. A housing member having a passage subject to contaminant pressure, has a rotary wear sleeve which is supported by bearings and is sealed to the housing by a plurality of spaced seals which define at least one and preferably two or more lubricant chambers for bearing lubrication and for hydrodynamic sealing. Lubricant pressure amplification cylinders are in fluid communication with respective lubricant chambers. Pistons moveable within each of the cylinders define differential surface areas exposed to lubricant and to contaminant pressure. Contaminant pressure acts on the pistons and develops lubricant pressure which is different, preferably higher, but can be lower than contaminant pressure. When lubricant pressure is higher than contaminant pressure it acts directionally toward contaminant pressure or environment pressure to minimize the potential for contaminant intrusion into the lubricant chambers and also enhances the hydrodynamic wedging of the lubricant into the dynamic sealing interface between the seals and the rotary member for enhanced service life of the seals even under high pressure conditions.

We propose to shape the leaf by the use of electro-chemical machining (ECM). ECM is a technique by which a blank is suspended within a mould, with a small gap therebetween. A conductive fluid is caused to flow through the gap, and a large electrical current is passed from the mould to the blank. The blank steadily erodes, dissolving into the fluid. The fluid should not provoke a reaction from the material of the blank, such as a surface oxide. Sodium Chloride solution is a common choice. The current that is passed can, if desired, be controlled to a profile that will affect the manner of erosion. Thus, the current profile can be a steady on / off current, or it can be pulsed. One known arrangement is for the current to rise to a peak, then fall to zero, followed by a brief reverse flow.
