Abstract: According to one general aspect, an apparatus may include a latch circuit configured to, depending in part upon a state of an enable signal, substantially pass the first clock signal to an output signal. The latch circuit may include at least two transistors configured to essentially perform a NAND function and controlled by a second clock signal, wherein the at least two transistors are configured to alter the timing of the substantial passing of the first clock signal to the output signal.

Abstract: According to one general aspect, an apparatus may include a power header and a logic circuit. The power header may include a gate terminal, a first channel terminal, a second channel terminal, and a bulk terminal coupled with a first voltage power signal. The power header may be configured to perform one of dynamically coupling or decoupling a logic circuit with the first voltage power signal. The logic circuit may include a bulk terminal coupled with a second voltage power signal and a power terminal that is either dynamically coupled or decoupled, as determined by the power header, with the first voltage power signal. A power sequencing signal may be included in the apparatus and may be configured to control the power header such that, when active, the power header couples the logic circuit with the first voltage power signal after the second voltage power signal is high.

Abstract: A bi-fold dinghy, which is foldable from front to back, is being claimed in this application. It will be easily stowed and transported on the back of a sailboat or other vessel like the traditional dinghy. It will allow individuals to get to and from the boat and ashore while also economizing space but having all the safety features of a dinghy.

Abstract: A multi-staged boundary layer engine and process cell, (based on the effect known as adhesion and viscosity) which achieves high thermal efficiencies and high mechanical power output for use in the power generation, geothermal, energy recovery, solar, transportation, hydrogen production, desalinating water and hydroelectric fields. The design is novel with a dovetail attachment of the disc packs, allowing lower stress and allowing the use of next generation materials such as ceramics, composites and nanocomposites to improve the maximum temperature and the maximum RPM of the engine, thereby producing more horsepower and torque. In addition, this invention includes multi-stage vacuum, an external combustion chamber and condenser stages to improve the vortex flow through the primary disc pack cell. This engine will also encompass a closed loop cycle for ultimate efficiencies.

Abstract: A foam dam in the insulation cavity of an electric water heater comprises a plastic bag into which liquid foam insulation is injected, the bag having an essentially closed top edge portion with only a small opening for receiving the injected insulation. A small portion of the insulation injected into the bag is forced outwardly therefrom via small metering holes to form external protrusions on the bag that mechanically interlock with a second batch of insulation subsequently injected into the cavity and prevent the hardened second insulation batch from pulling away from the bag. The substantially closed top edge of the bag permits the insulation injected into the bag to pack therein and increase the top-to-bottom hardened foam density uniformity. Side edges of the bag may be pleated to increase the sealing area of the foam dam.

Abstract: Electrical components projecting outwardly from the storage tank portion of an electric water heater are shielded from foam insulation material being injected into an insulation space between the tank and an outer jacket portion of the water heater by a hollow, open sided foam dam structure extending through a jacket opening and circumscribing the electrical components. Force exerting projections on the dam engage the interior side surface of the jacket and forcibly hold the inner side of the dam structure in sealing engagement with the tank. The projections also hold an outer side peripheral lip of the dam in a an outwardly and resiliently deflected orientation in which it is sealingly pressed inwardly against the outer side surface of the jacket around the periphery of the opening therein to prevent injected foam from being forced outwardly through the jacket opening.

Abstract: A method and apparatus for lining a pipe with a polymer liner in which the liner is pulled through a die to reduce the liner's diameter and through the pipe and on removal of the pulling load, allowing the liner to revert to at least the minimum internal diameter of the pipe, wherein the liner has a maximum diameter before entering the die and a minimum diameter in the die. The die having an aperture which is symmetrical with respect to a central, longitudinal axis and comprising in the direction that the liner is passed an entry, a throat and an exit. The diameter of the aperture decreasing over the entry to a minimum to the throat and increasing over the exit. The entry of the die, when viewed in a sectional plane extending longitudinally of the liner and containing the axis, is convex over substantially an entire axial length between where the liner first contacts the die and the throat, wherein the liner substantially continuously engages the die over substantially the entire axial length.

Abstract: A die for reducing polyethylene pipe temporarily to enable it to be inserted in a pre-existing metal pipe is made of cast iron and has formations by which the die is splittable into two portions. The formations receive cylindrical bars which are squeezed together by a hydraulic squeeze off machine. Each formation is a U-shaped aperture with a saw cut extending from the base of the U into the ligament beneath the formation. The saw cut acts as a stress raiser. In a modification only one formation is provided. The die is made of grey cast iron or some other brittle material.
