Abstract: A speed controller maintains the engine throttle at a desired throttle position based upon an initial throttle position and a speed error signal. The initial throttle position is generated by multiplying vehicle speed by a constant and adding an offset value related to throttle position at idle and speed control slack. The initial throttle position is adaptively updated by subtracting the above product from actual throttle position during speed control operation to learn a new offset value.

Abstract: An optical amplifier comprises an erbium-doped, silica-based optical fibre (6) coupled to a second optical waveguide, comprising a fibre (4) having a D-shaped cross-section. The second optical waveguide (4) has an overlaid grating (10) formed on a silica wafer (9) which is constructed and configured so that the waveguide filter provides loss in transmission substantially at the wavelength of the gain peak of the amplifier. The resonant reflection wavelength is chosen to be substantially equal to, or greater than; the wavelength of the gain peak of the amplified gain spectrum.  Transmission losses at wavelengths shorter than the resonant reflection wavelength of the grating act to reduce the gain peak thereby flattening the gain spectrum of the amplifier so providing a larger useful gain bandwidth for optical fibre systems having a cascade of such fibre amplifiers.

Abstract: An improved handtruck having an unloader mechanism for assisting in the removal of cargo from the handtruck. The unloader mechanism utilizes a cargo support (28) pivotally mounted at the lower end of the handtruck. The cargo support (28) is designed so that it can be maintained in a latched position when transporting cargo and can be unlatched to pivot away from the handtruck when unloading cargo. A pusher structure (30) may be operatively connected to said cargo support to facilitate the removal of cargo from said cargo support. The pivot action of the cargo support causes a force to be exerted on the cargo by the pusher structure which urges such cargo down an inclined plane formed by the cargo support, thereby removing the cargo from the handtruck.

Granted: 1999-08-17
Abstract: An air manager system is disclosed which maintains a more stable water vapor and carbon dioxide equilibrium across the air cathode of a metal-air cell while still providing new oxygen needed for operation of the cell at desired power levels. Oxygen is preferentially drawn in through one or more ventilation openings (17) in a housing (15), so that the concentrations of water vapor and carbon dioxyde in the battery housing remain more stable, resulting in less transfer across the cathode (30). A fan (20) circulates the gases within the battery housing, keeping the oxygen needed for operation of the cell in contact with the air cathode eventhough the oxygen concentration within the housing is reduced compared to the ambient air outside the housing. Therefore, the cell is less susceptible to drying out or flooding, and less carbon dioxyde intrudes into the cell.

Abstract: A fastener assembly and method for attaching a first member to a second member. The fastener assembly includes a socket member which defines a socket and a stud which includes a head engagable with the socket of the socket member. The stud is attached to a first member and the nut is attached to a second member. The assembly is initially attached to the first member by attaching the stud to the first member and then inserting the nut into the second member. When the first member must be removed from the second member, the head of the stud is forcibly disengaged from the socket of the socket member. Reattachment of the first member the second member is achieved by forcibly engaging the head with the socket. After the initial insertion, the socket member remains captively retained on the second member.

Abstract: The arrangement for treating combustion residues of a combustion installation comprises an ash discharges (1) into which opens a fall shaft (2), into which the solid combustion residues fall from a furnace grate. The ash is conveyed from the ash discharges (1) into the discharge shaft (7) via a diagonally ascending push-out chute (3) by means of a push-out ram (6) whose operating rate is so adjusted that the ash (11) is piled up in the fall shaft (2) in a tower formation reaching above the liquid level (9). Fresh water or a chemical is introduced into the discharge shaft (7) via an inlet (8). The ash discharges water present in the ash discharges and charged with fine particles is drained into a hermetically sealed settling tank (17) via a draw-off duct (18). Ash discharges water, with which a chemical can be mixed via another line (19a), is fed from the upper region of the settling tank (17) by a pump (20) via a return line (19) to spray nozzles (13) which are arranged in the upper region of the fall shaft (2). Ash discharges water which is enriched with solids particles is drawn off from the bottom of the settling tank via another pump (23) which is arranged in an outlet line (21) proceeding from the settling tank. This is effected at a rate such that solids particles having a diameter of up to 2 mm are carried away with the ash discharges water which is drawn off through the draw-off duct (18).
