A fluid filter includes a bypass valve and a pleated media surrounded by a thermoplastic frame. A fluid filter, includes a housing having an inlet and an outlet, a media disposed within the housing, a bypass valve disposed within the housing adjacent the media wherein the bypass valve includes a valve frame, a valve lid that couples to the valve frame, a valve pan that couples to the frame, and a seal door disposed between the valve lid and the valve frame. A method of filtering fluid, includes providing a bypass valve wherein the bypass valve includes a bypass valve seal door, raising the bypass valve seal door along a guide disposed on the bypass valve, passing fluid through the raised bypass valve seal door, lowering the bypass valve seal door along the guide disposed on the bypass valve and ceasing passing fluid through the bypass valve.

A belt installation tool having a first member (18) engagable with a pulley hub whereby a belt installation radial load is transmitted to the pulley hub. A body (10) having a tool engagement portion (15) disposed radially from the pulley hub. A second member (11) radially extending from the body opposite the first member, the second member having a lateral urging surface (12) for laterally urging a belt into a pulley groove. A roller (17) having a conical surface (17A) extending normally from the body at a radius substantially equal to or less than a pulley flange radius and in a direction opposite a pulley, the roller cooperatively disposed with the lateral urging surface whereby a belt is borne from the roller to the lateral urging surface during belt installation.

A chemical reactor and method of using the same. The reactor comprises first and second micro-engineered discrete flow passages for receiving chemical fluids. The first fluid passage receives a first chemical fluid in which a chemical change or reaction in the fluid can be initiated by subjecting the fluid to a stimulus. A stimulation means is located in, or adjacent to, the first flow passage, and is operable to stimulate a chemical change or reaction in the first fluid. The second micro-engineered discrete flow passage receives a second chemical fluid which will interact with the stimulated first fluid when contacted by the stimulated first fluid. The first and second flow passages converge at a first region to form an outlet passage within which the first and second fluids may contact each other.

A Dual Input, Single Output Low Dropout Regulator (LDO) includes two linear regulator circuits and control circuitry that produce an overlap period during change-over between a regulated supply voltage and an unregulated supply voltage wherein both supply voltages are coupled to the LDO output pin. The unregulated supply voltage is supplied, e.g., by a battery, and the regulated supply voltage is supplied from a switching-type DC-DC converter. First and second output devices are connected between the LDO output terminal and the unregulated and regulated supply voltages, respectively. The first regulator circuit causes the first output device to supply the desired regulated output voltage while the switching regulator ramps up. The regulator circuits then turn on the second output device and gradually turn off the output device, whereby the regulated output voltage transitions from the unregulated supply voltage to the regulated supply voltage is achieved without severe voltage transients.

A centralizer for a pipe or other elongate member is formed from a plurality of tubular bodies (16) each having a through passage (23) that is connected end-to-end to form a continuous passageway. Each of the tubular bodies (16) has a female connector portion (26) at one end and a male connector portion (24) at the opposite end that fits into the female connector portion (26) with longitudinal and/or angular play. The securing means in the form of a mounting flange (14) is also provided to fix the centralizer with respect to a J-tube through which the centralizer is to pass. The invention centralizes the elongate member in the J-tube and maintains the allowable minimum bending radius, whilst eliminating, or reducing to acceptable levels, the contact loads and abrasion on the elongate member.
