Abstract: An apparatus for gripping and lifting objects such as construction castings has a T-shaped frame comprising elongate horizontal and vertical frame members. The vertical frame member is slidably received in one end of a hollow sleeve member which is connected to its upper end to a lifting means such as a loop or hook. A pair of articulated pivot arms are each connected at one end to the hollow sleeve member and at the other end to the horizontal frame member, with a joint being provided between the ends of each pivot arm. Carried at the ends of the horizontal frame member are a plurality of contact members which are adapted to contact and grip the sidewall of a construction casting. In use, the apparatus is placed over a construction casting with the horizontal frame member resting on the upper surface and with the contact elements in position facing the side wall of the casting. The apparatus is then lifted, for example by a backhoe or loader, which causes the sleeve member to slide upwardly along the vertical frame member. This causes the pivot arms to lift, and brings about an inward and upward pivoting movement of the contact elements, causing them to engage and grip the side wall of the casting. The gripping force increases with the weight of the casting.

Abstract: The invention provides an apparatus for estimating fuel-cell hydrogen concentration and a fuel cell system which exploit the correlation between impedance semicircles and hydrogen concentrations to estimate fuel-cell hydrogen concentration. A fuel cell system includes a fuel cell 2, an impedance measuring instrument 3, and a control device 5. The control device 5 is connected to the impedance measuring instrument 3.  The impedance measuring instrument 3 measures the impedance of the fuel cell 2 according to the AC impedance method. The control device 5 stores in advance a reference value corresponding to a reference hydrogen concentration. The control device 5 compares the real part Z' of impedance acquired via the impedance measuring instrument 3 against the reference value.  When Z' is equal to or greater than the reference value, the control device 5 estimates the hydrogen concentration of the fuel cell 2 to be equal to or less than the reference hydrogen concentration.

Granted: 2014-12-09
Abstract: An internal combustion engine that includes a rotary device is disclosed. A rotary head has an expansion chamber that includes intake and exhaust slots. A drum with axial slots radially displaced over its circumference is disposed in close noncontacting proximity to the inner side of the rotary head. The drum and the rotary head are substantially rotationally symmetric about a common axis. Radially moveable plates respond to a mechanical control mechanism adapted to move each plate from a retracted position in which the plate is located entirely within the outer surface of the drum and an extended position in which the plate is in close proximity to an upper surface of the expansion chamber to substantially seal the expansion chamber. At least one of the plates is substantially always present between the intake slot and the exhaust slot such that when the combustion gas is under pressure within the expansion chamber force is exerted on the plate and the drum to produce rotational motion of the rotary head about the common axis.
