摘要:
A resistance heating system is provided which includes a resistance heater, a source of alternating current electricity connected by conductors to the resistance heater, and a controller comprising a timer arranged to connect the source of alternating current electricity to the resistance heater for a selected time period and to disconnect the source from the resistance following the selected time period. In an embodiment, the resistance heating system is provided with a controller configured to be connected to a source of alternating current electricity and having a plurality of cable plug receptacles arranged to receive electricity. An electricity conducting cable having a cable plug at one end is configured to be received in the receptacles and has a resistance heater provided at an opposite end. A master timer may be connected with a communication arrangement to the controller. The master timer is arranged to control an electric output of a plurality of the receptacles.

The present invention provides a wrench socket that has a driven end for receiving a driving wrench in an internal or female drive opening, a driving end for engaging a threaded fastener to transmit a driving torque to the fastener and an intermediate external or male drive surface area which can be engaged by a second driving wrench. A removable retaining member is provided to assure that the second wrench is held on the socket, and a series of sockets may be provided which have various sized driving ends, but all have identical sized female drive openings and identical sized male drive surface areas so that only a single sized first wrench or a single sized second wrench need be used to drive a range of sizes of threaded fasteners. The driving end can be in any form, such as a castellated opening, a female hex-shaped opening or a male hex-shaped projection.

In time-delay-and-integrate (TDI) imaging, a charge-couple device (CCD) integrates and transfers charge across its columns. Unfortunately, the limited well depth of the CCD limits the dynamic range of the resulting image. Fortunately, TDI imaging can be implemented with a digital focal plane array (DFPA) that includes a detector, analog-to-digital converter (ADC), and counter in each pixel and transfer circuitry connected adjacent pixels. During each integration period in the TDI scan, each detector in the DFPA generates a photocurrent that the corresponding ADC turns into digital pulses, which the corresponding counter counts. Between integration periods, the DFPA transfers the counts from one column to the next, just like in a TDI CCD. The DFPA also non-destructively transfers some or all of the counts to a separate memory. A processor uses these counts to estimate photon flux and correct any rollovers caused by “saturation” of the counters.

When imaging bright objects, a conventional detector array can saturate, making it difficult to produce an image with a dynamic range that equals the scene's dynamic range. Conversely, a digital focal plane array (DFPA) with one or more m-bit counters can produce an image whose dynamic range is greater than the native dynamic range. In one example, the DFPA acquires a first image over a relatively brief integration period at a relatively low gain setting. The DFPA then acquires a second image over longer integration period and/or a higher gain setting. During this second integration period, counters may roll over, possibly several times, to capture a residue modulus m of the number of counts (as opposed to the actual number of counts). A processor in or coupled to the DFPA generates a high-dynamic range image based on the first image and the residues modulus m.

The present invention is directed to a method of capitalizing a bank holding company by, for example, providing a capital structure for the bank holding company that includes multiple tranches of one or more series of common stock, each tranche corresponding to one of a number of classes of ownership rights in the bank holding company. Each share of common stock associated with one or more of the tranches will have a capped dividend paid out at a predetermined rate whose value is dependent on the particular one of the tranches that the share of common stock is associated with.

An induction heating device having a pair of inductors in a sub-assembly connected by fluid conduits to a cooling apparatus and by electrical conductors to an inverter and impedance adjusting circuit has a quick disconnect terminal assembly arranged closely adjacent to the inductors. This permits the inductor sub-assembly to be quickly and easily disconnected from the conduits and conductors so that the inductor sub-assembly may be moved to a new location easily and quickly. A plurality of inductor subassemblies may be used with a single terminal assembly to provide an accelerated method of heating a series of items by successively moving the terminal assembly to a next inductor sub-assembly to begin heating and to then move the non-disconnected inductor assembly to a new location while the next inductor sub-assembly is operating.

A tool for cleaning parts of a bowling machine. The tool includes a base plate having a handle pivotally secured thereto between two opposed side walls and including a planar forward portion having a notch therein which is adapted to manipulate a latch in a bowling machine. A cleaning cloth is provided to substantially cover the base plate and outward portions of the side walls.

During this second integration period, counters may roll over, possibly several times, to capture a residue modulus 2m of the number of counts (as opposed to the actual number of counts). A processor in or coupled to the DFPA generates a high-dynamic range image based on the first image and the residues modulus 2m.
