Abstract:
The present invention provides a lightweight sleeve and spool arrangement for use in certain pumps. Such lightweight sleeve and spool arrangement comprises a sleeve having a predetermined number of apertures and having a predetermined interior diameter. The sleeve is formed from a first predetermined plastic material selected from a group consisting of nylons, acetals, polysulfones, polyesters, polyetherimides and polyamide-imines. There is also a spool that has a predetermined configuration and a predetermined exterior diameter. Such predetermined exterior diameter being about 0.0005 inches smaller than the predetermined interior diameter of such sleeve. The spool is formed from a second predetermined plastic material selected from a group consisting of nylons, acetals, polysulfones, polyesters, polyetherimides and polyamide-imines.
Abstract:
An infant care apparatus convertible between a bassinet and changing table, including a carrier removable from a support frame for transporting an infant. The carrier is placed upon the frame for use as a bassinet. The frame also supports a changing table surface exposed for use with the carrier removed. The base of the frame includes retractable wheels and rockers. The frame is releasably securable to an adult bed for co-sleeping.
Abstract:
An endplate for attachment to a stator frame of an electric motor used to drive an air compressor. The air compressor has a crankshaft rotationally supported by at least one rotational bearing, and the electric motor includes the stator frame, a stator element mounted to and within the stator frame, and a rotor element rigidly mounted on a portion of the crankshaft for rotation therewith. The crankshaft projects through the stator element and terminates in a distal end. The endplate is adapted for mounting to the stator frame so as to provide support for mounting an additional rotational bearing for rotationally supporting the distal end of the crankshaft on an opposite side of the rotor from the at least one rotational bearing. The endplate includes a cap member and an attachment mechanism for attaching the cap member to the stator frame, the cap member including a rotational bearing housing for mounting and positioning a rotational bearing thereon and the rotational bearing housing being substantially positioned in juxtaposition to the distal end of the crankshaft when the cap member is attached to the stator frame by the attachment mechanism. Also disclosed is a kit for retrofitting an electric motor driven air compressor so as to provide the electric motor driven air compressor with such an outboard rotational bearing.
Abstract:
A potted timer and circuit board assembly for use in a regenerative desiccant air dryer. The potted timer and circuit board assembly comprise a support member of a predetermined size and shape having a first surface and a second surface. A conductive pattern of a predetermined material and thickness is disposed on at least one of the first surface and the second surface of the support member. A predetermined quantity and arrangement of electronic components of a predetermined voltage is disposed on at least one of the first surface and the second surface of the support member for providing a timed electronic signal to a solenoid valve that pneumatically operates an air dryer. A non-conductive material of a predetermined composition encases the electronic components on the support member for insulating the electronic components from environmental elements. The support member has at least one exposed member on a side of the support member for engagement with at least one receptacle on such air dryer for creating an electrical current in the potted timer and circuit board assembly. An alignment means is disposed on at least one of opposing sides of the support member for engagement with at least one slot in such air dryer for aligning and holding the potted timer and circuit board assembly in a predetermined position in such air dryer.
Abstract:
A shaft extension for attachment to a crankshaft of an electric motor driven air compressor to axially extend the crankshaft for engagement with an outboard rotational bearing. The electric motor driven air compressor includes a bearing plate, an inboard rotational bearing mounted on the bearing plate, the crankshaft projecting through both of the inboard rotational bearing and the bearing plate and terminating in a distal end disposed exterior of the bearing plate. The air compressor also includes an electric motor, the electric motor having a stator frame, a stator fixedly mounted within the stator frame, and a rotor fixedly mounted to the crankshaft for rotation therewith and disposed interior of the stator. The air compressor further includes the outboard rotational bearing disposed axially outboard of the stator frame, the stator, and the rotor. The shaft extension includes an extension member having an extended major axis and a minor axis extending substantially transverse to the extended major axis and a connection mechanism for connecting the extension member to the distal end of the crankshaft.
