Abstract: A centrifugal fan assembly includes an impeller assembly which has a fixed stator and a rotating impeller having a base plate, a hub connected to the base plate a plurality of backward curved first blades, and a plurality of backward curved second blades. Each first blade has an inner end which is connected to the hub. Each second blade has an inner end which is spaced apart from the hub and which tapers to a point. The first and second blades have different profiles or shapes. The axial length of the first blades is different from the axial length of the second blades. Each second blade forms an apex which projects axially from the base plate.

Abstract: A vehicle cooling system includes a fan, a radiator upstream of the fan and in a first air flow path, a charge air cooler upstream of the radiator in the first air flow path, a fuel cooler upstream of the radiator in the first air flow path, and a hydraulic oil cooler adjacent to a side of the radiator and upstream of the fan and in a second air flow path which is parallel to the first air flow path. A condenser is positioned in the first air flow path between the fuel cooler and the radiator. The hydraulic oil cooler has an upstream side which is unobscured by any other cooling system components. The hydraulic oil cooler includes first and second hydraulic oil cooler units connected together in series. A portion of the hydraulic oil cooler is positioned above a top side of the radiator.

Abstract: A seal requiring no compression type clamp is provided for a drain nipple-hose assembly having a tubular tapered drain nipple projecting from a structure to be drained and a corrugated hose for placing over the drain nipple. The seal includes a hollow flexible inner sleeve and a hollow outer sleeve which is longer than the outer sleeve. The seal also includes an annular wall member which joins an end of the inner sleeve to an end of the outer sleeve. The inner sleeve is stretched over the drain nipple between the drain nipple and the hose so that the inner sleeve sealingly engages the drain nipple and the hose. The outer sleeve surrounds an end of the hose. The wall member has a curved sectional shape, which is concave in a direction in which the drain nipple opens to the hose.

Abstract: The invention relates to a method of control fan speed in a fan speed control system having a cooling fan driven by a motor, a motor driver for driving the motor at a speed corresponding to a fan speed control signal, and an electronic control unit (ECU) for generating the fan speed control signal. The method includes generating a fan speed control signal and communicating the fan speed control signal to the motor driver so that the motor driver drives the motor at a speed corresponding to the fan speed control signal. If the fan speed control signal is at a level below a noisy fan speed range, then the ECU maintains the fan speed control signal below the noisy fan speed range until the ECU commands a fan speed above the noisy fan speed range. If the fan speed control signal is at a level above the noisy fan speed range, then the ECU maintains the fan speed control signal at a level above the noisy fan speed range until the ECU commands a fan speed below the noisy fan speed range.

Abstract: A statement printer in an automated teller machine includes a guide block (86) which supports a print head (110). The print head prints on paper (130) which is moved adjacent thereto as the guide block moves transversely relative to the paper. A cutter disk (76) is supported by the guide block. The cutter disk is journaled on an arm (82). The arm is connected to an actuating lever (92). The actuating lever is engageable with stops (106) near the transverse extremes of travel of the guide block. Selective engagement of the actuating lever with the stops moves the cutter disk between cutting and non-cutting positions. Cam members (108) adjacent to the stops dispose the cutter disk away from a cooperating cutter bar (74) as the cutter disk moves between the cutting and non-cutting positions.

Abstract: A statement printer of an automated teller machine includes a top plate (16) pivotally mounted on a pair of spaced side walls (12). The top plate supports a ribbon cartridge (18) thereon. The cartridge includes a pair of downward extending projections (38) which are accepted in a longitudinally extending recess (24) in the top plate. Notches (40) and the longitudinally extending projections engage a leaf spring (28) to position the cartridge thereon. The top plate further includes a pair of finger projections (30) having slots (34) for accepting wing projections (36) that extend from the sides of the cartridge. The guided relationship between the downward extending projections and wing projections on the cartridge and the longitudinal recess and the slots on the top plate enable the cartridge to be guided into position on and off the top plate which facilitates changing the cartridge in the confined space inside an automated teller machine.
