Title: Rotatable handle for disposal spool
Inventor: BLACK RONALD L
IPC: B65H75/40
Filed: 1997-02-27
Abstract: A line reel for dispensing string, construction line, or cord includes a cap that can be inserted into one end of a spool holding the material to be dispensed, a midsection that can be inserted into the other end of the spool, and a rotatable handle connected to the midsection on the opposite side from the spool. In one embodiment, the cap and midsection frictionally engage the inside of the spool and can be pulled out of the spool for re-use with another spool. In an alternate embodiment, a latch structure on the cap and midsection latches the cap to the midsection in the spool so they cannot be easily removed from the spool once assembled. The line reel includes a notch to hold the free end of the construction line or string. The cap, spool, and midsection, while positioned structurally so that they do not rotate in relation to each other, are able to rotate in relation to the handle to facilitate dispensing the construction line.

Title: Device and method of creating aerosolized mist of respiratory drug
Inventor: SCHUSTER JEFFREY A
IPC: A61M16/10
Filed: 1995-10-27
Abstract: Devices are hand held, self-contained units which are automatically actuated at the same release point in a patient's inspiratory flow cycle. Actuation of the device forces respiratory drug through a porous membrane (3) of the container (1) which membrane has pores having a diameter in the range of about 0.25 microns to 6.0 microns. The porous membrane (3) is positioned in alignment with a surface of a channel (6) through which a patient (10) inhales air. The flow profile (12) of air moving through the channel is such that the flow at the surface of the channel is less than the flow rate at the center of the channel. The membrane is designed so that it protrudes outward at all times or is made flexible so that when respiratory drug formulation (5) is forced against and through the membrane, the flexible membrane protrudes outward beyond the flow boundary layer (13) of the channel into faster moving air.

Patent CA-2219773-A1 (CA)
Title: Housing for regenerative heat exchanger
Inventor: SNIDER REX RICHARD
IPC: F23L15/02
Filed: 1996-03-25
Abstract: In an air preheater with a large lower cold end center section and a smaller, upper hot end center section, the connecting plate duct assemblies on both the hot and cold end are made the same height rather than to have cold end connecting plate duct assemblies which are larger and equal in height to the cold end center section. This minimizes the design and manufacturing costs and provides cold end connecting plate duct assemblies which are smaller, lighter and easier to handle. This then requires that the housing panels around the outside of the rotor be longer to reach between these connecting plate duct assemblies. At the ends of the hot and cold center sections are main support pedestal panels which support the hot end center section above the cold end center section. These main support pedestal panels together with the housing panels complete the rotor housing. In order to compensate for the difference in the height of the cold end center section and the hot end center section and the resulting difference in the distance between the hot and cold center section and between the hot and cold connecting plate duct assemblies, the main support pedestal panels include offsets which extend downwardly along the sides of the cold end center section to meet with the cold end connecting plate duct assemblies.
