An automatic clothes dryer comprises a cabinet adapted for support on a support surface and defining an interior space. A drum is rotatably mounted within the interior space and defines a drying chamber. A drive motor is mounted within the interior space and has an output shaft operably coupled to the drum for rotating the drum. A blower is mounted within the interior space and is fluidly coupled to the drying chamber for moving air through the drying chamber. The blower has a drive shaft remote from the output shaft to permit the independent positioning of the blower and drive motor within the interior space. The blower has an outlet fluidly connected to an exhaust outlet through a conduit that defines an air flow path having less than a 90 degree change in direction.

A water-soluble or dispersible, hydrolytically stable polysaccharide preferably selected from the group consisting of poly-glucan, poly-mannan, gluco-mannan and mixtures thereof. Which is covalently linked by a hydrolytically stable bond to a first polymeric textile softening species (typically a silicone) and optionally emulsified with a second polymeric textile softening species. The specification also discloses laundry treatment composition comprising these compositions.

A microprocessor including memory storage into which ISA customer code routines can be stored after having been decoded into their machine-native microinstructions. The customer code store is not subject to eviction and the like, as a cache memory would be. ISA level code can specify a routine for storage into the customer code store, at a time prior to its execution. The customer code store thus serves as a write-once execute-many library of pre-decoded routines which ISA level applications can subsequently use, permitting a system manufacturer to create a highly customized and optimized system.

A cooled acoustic liner useful in a fluid handling duct includes a resonator chamber 52 with a neck 56, a face sheet 86, and a coolant plenum 80 residing between the face sheet and the chamber. Coolant bypasses the resonator chamber, rather than flowing through it, resulting in better acoustic admittance than in liners in which coolant flows through the resonator chamber and neck. In one embodiment, the liner also includes a graze shield 88. Openings 40, 38 penetrate both the face sheet and the shield to establish a relatively low face sheet porosity and a relatively high shield porosity. The shielded embodiment of the invention helps prevent a loss of acoustic admittance due to fluid grazing past the liner. Another embodiment that is not necessarily cooled, includes the resonator chamber, low porosity face sheet and high porosity shield, but no coolant plenum for bypassing coolant around the resonator chamber. An associated method of retrofitting an acoustic treatment into a fluid handling module includes installing openings in the module and mounting a resonator box 44 on the module so that the inlets to the resonator necks register with the installed openings.

An optical scanner is provided having a memory device thereon. The memory device may store operational characteristics of the optical scanner or data that characterizes laser beam scan path and/or laser power requirements by each laser of the optical scanner. The memory device may be used to store historical information such as device temperature, cycles of operation and other historical information of components within a corresponding electrophotographic device. Still further, the electrophotographic device to which the optical scanner is installed may write operational data to the memory device, for example, to store a backup of registration and other operational parameters that are typically stored by the controller of the electrophotographic device.

A laser scanning unit is provided. It comprises a housing; a scanning device; a pre-scan assembly generating a light beam and directing the light beam toward the scanning device; and a post-scan optical assembly receiving a scanning beam reflected from the scanning device and causing the beam to traverse a photoconductive member along a scan path. The post-scan optical assembly comprises a sensor for detecting the beam at a start-of-scan location and an end-of-scan location along the scan path.

A press-in fastening apparatus and method couples a screw with a nut by pushing the screw through an opening of the nut along a slip axis and rotating the nut to align a lock axis with the inserted screw. The opening of the nut along the slip axis has a diameter greater than the diameter of the screw and the opening of the nut along the lock axis has a diameter that engages screw threads with nut threads. In one embodiment, the nut is disposed in a housing coupled to an information handling system and biased to align with the lock axis so that a module is secured to the information handling system by aligning a screw coupled to the module with the nut and pushing the screw into the nut. The module is removed from the information handling system by unscrewing the screw with engagement of the screw threads and nut threads.

A cutting tool for a milling, drilling or turning machine has a body with a plurality of sides and a central opening. Each side has a perimeter along which cutting planes or edges are formed. Each side has at least two such cutting planes or edges. The planes may have a straight or curved profile, or a combination of straight and curved profiles along one side. The tool may have a plurality of such cutting planes formed along each side of the tool body. The cutting planes may be located at different levels in relation to each other, entering a work piece in sequence, or may be aligned to enter the work piece simultaneously. Preferably, the cutting planes are staggered in two directions—in a feeding direction and in a cutting direction. By dividing each surface being cut into a plurality of segments, the cutting tool creates a plurality of distinct shavings, or splinters that have shorter length in comparison with conventional splinters formed by indexable tips. Shorter cuts require less cutting force, which saves wear on the cutting tool and the machine. At the same time, the cuts can be made deeper and smoother when dividing the cutting surface into a plurality of segments.
