Abstract: A dehumidifying air handling unit for a heating, ventilation, air conditioning, and refrigeration (HVACR) system includes a housing, a hollow desiccant drum configured to rotate within the housing, and a heat exchanger disposed within the hollow desiccant drum. The hollow desiccant drum includes channels that extend through a sidewall that surrounds an interior space. A desiccant is provided in the channels. The heat exchanger is configured to cool air flowing through the interior space of the hollow desiccant drum. A method of conditioning air includes rotating a hollow desiccant drum within a housing and directing the air to pass through the hollow desiccant drum.

Abstract: A rocker shoe has a lower rocker surface extending across the plantar surface of the shoe sole from the heel and terminating short of the toe. A rocker shoe construction kit has a rigid or substantially rigid rocker piece having an upper surface for securing over a major portion of a lower plantar surface of the sole of a shoe upper and a lower surface of predetermined rocker shape, a cushioning layer for securing over the lower surface of the rocker piece, and a layer of tread material configured for securing over the lower surface of the cushioning layer and any exposed portion of the plantar surface of a shoe.

Abstract: The present invention provides a plastic tray orthodontic device (11) which may have embedded activators (10) and which is provided with an over-shell (12). The over-shell (12) acts as a force module.

Abstract: A convertible buccal tube is disclosed which includes an arch wire slot covered by a separable cover. The cover includes a mesial or front flared portion to facilitate placing the end of an arch wire therein without undesirably stressing the cover. The cover is further secured to the buccal tube body by integral seams, brazing or other adhesive means that are varied in strength mesially-distally, with about 50% greater force being required to separate the cover at the mesial end thereof. The cover and increased strength seams provide that the cover is not prematurely separated from the buccal tube, particularly during installation of an arch wire.

Abstract: An orthodontic appliance may easily be recognized by a sort and a tooth mark, and trace to confirm the history of material and the production process. The appliance has a production lot number indicated at the part thereof, and further, the sort and the tooth mark indicated at an easily recognizable place thereof.

Abstract: An orthodontic appliance has a tooth-abutting surface oriented at an acute angle relative to the base of an arch-wire slot. A lip bumper tube of the appliance is reverse offset relative to the base of the arch-wire slot to obtain more accurate manipulation of the force and torque vectors applied to the tooth. The angle of the base also reduces occlusal interference by gingivally inclining the lip bumper. Wedge-shaped occlusal tie wings further reduce occlusal interference. An auxiliary hook of the appliance is shaped so that its extension in the buccal direction is less than that of the lip bumper tube to reduce patient irritation and discomfort.

Abstract: A defense weapon, comprising a toe boot which fits over the toe of a wearer's shoe and held securely in place by straps, one on each side of the toe boot, which are carried to the rear of a person's shoe, there tightly fastened and held by a belt and buckle type fastening device.To the front of the toe boot is attached a long steel bolt having a very sharp point, and having four sharp cutting blades, that are welded to the spike bolt, near the pointed end of the spike bolt; the blades are spaced at ninety degree intervals around the circumference of the bolt.The four bladed spike bolt can be unscrewed and carried with, and then when the defense weapon is needed, in times of danger, the bladed spike bolt can be screwed into the toe boot adapter, and hand tightened, making the defense weapon ready for use.

Abstract: A weed cutting device having a double edged, rectangular, shaped blade that is attached to and in front of a toe boot that fits over a user's shoe.
