Abstract: Nickel-based alloys having improved localized corrosion resistance, improved stress-corrosion cracking (SCC) resistance and impact strength are disclosed. The improvements come from the provision of compositions that are resistant to deleterious phase formation and from the addition of alloying elements that improve corrosion resistance, impact strength, and SCC resistance. The nickel-based alloys of the present invention have controlled amounts of Ni, Cr, Fe, Mo, Co, Cu, Mn, C, N, Si, Ti, Nb, Al, and B. When subjected to post-cladding heat treatments or welding, the nickel-based alloys retain their corrosion resistance and possess desirable impact strengths.

Abstract: An appliance lid for an appliance is disclosed. The appliance lid includes a viewing window; and at least one clamshell providing partial encapsulation of the viewing window using at least two parts surrounding the viewing window. The viewing window allows operation of the appliance to be observed. In one embodiment, the clamshell includes a top piece and a bottom piece encapsulating the viewing window. The appliance may be, for example, a top loading washing machine. The top and bottom pieces can be fastened to one another, for example, using an adhesive or one or more mechanical fasteners. One or more gaskets can optionally be provided along at least one edge of the viewing window. A magnet can optionally be embedded in the clamshell to provide a safety lock for the appliance.

Abstract: A device for adjusting the spring tension in a door closer in situ comprises body having a front side and back side surface. Mounting screw openings are disposed within the body and are positioned at locations corresponding to locations of selected locking screws in the closer used to secure a spring cover. Mounting screws are disposed within respective mounting screw openings. A centrally positioned cavity is disposed within the body and accommodates rotatable placement of an adjustment shaft therein. The adjustment shaft comprises a hexagonal head extending outwardly from the front side surface, and is attached to an adjustment assembly comprising a drive disk extending outwardly from the back side surface of the device. Adjustment pins extend outwardly from the drive disk and are numbered and configured to correspond to adjustment holes in the spring cover.

Abstract: A vibration damper for a transducer positioning system of a diskette system employing a stepping motor for driving a moveable transducer carriage that is coupled to the stepping motor drive means. The mass of the carriage and the coupling means form a vibratory system having a natural frequency of oscillation significantly different from the frequency of the pulses applied to the stepping motor so that while the motion of the carriage reflects the total motion of the shaft, the incremental motions of the shaft are not transmitted to the carriage thereby minimizing noise ancillary to the positioning of the carriage.

Abstract: Apparatus for moving a transducer carriage intermittently along a tract relative to a recording medium employs belting arranged in a closed loop that is tensioned by engagement around at least one idler and connected to the carriage. Belt end segments comprising the loop are wrapped in opposite directions around the periphery of a stepping motor-driven capstan and their ends are secured thereto at axially spaced apart locations thereon. The belting and idlers are arranged so that all of the belt segments wrapped around the capstan remain parallel to the carriage track as the capstan rotates so as to advance the carriage a maximum number of increments along its track.

Abstract: A floppy disk drive system employs an inside-out DC motor whose centrally located stator is mounted directly to the chassis. The motor has a tubular rotor that encircles the stator and it is supported co-axially with the stator by the rotary disk drive spindle. A timing and commutation disk is mounted directly on the rotor and, together with speed control and commutation networks, maintains uniform motor speed.
