  • Patent number: 6539731
    Abstract: A humid gas stream is dehumidified by bringing that stream into contact with the front surface of a hydrophilic capillary condenser layer that captures the water and moves it adjacent the rear surface of the capillary layer. An osmotic layer, such as a semi-permeable membrane, is disposed on the rear surface of the condenser layer, and an osmotic fluid having a low concentration of water therein, is disposed adjacent the osmotic layer. An osmotic driving force, resulting from the water concentration gradient across the osmotic layer, transports the condensed water from the condensing layer through the thickness of the osmotic layer and into an osmotic fluid. The osmotic layer also inhibits the osmotic fluid from flowing into the condenser layer.

  • Patent number: 6536228
    Abstract: A dry-compartment cooler has a dry compartment (1) with compartment walls (3) that are connected water-tightly to a compartment floor (4). The compartment walls are articulated to extend upwardly from proximate a riser framework (6) on a cooler floor (7) to proximate a bottom side of a cooler lid (8) of a predetermined cooler. One or more ice compartments (10, 11, 12, 13, 14) separate ice and water from inside surfaces of the compartment walls and from space inside of the dry compartment. The ice compartments are in fluid communication intermediate proximate the bottom side of the cooler lid and riser-framework space (9) where the riser framework is positioned under the compartment floor. The compartment walls can have heat-conveyance members (27) for conveying coldness and for deterring moisture formation on food and other items being cooled.

  • Patent number: 6514230
    Abstract: Described is an electronic injection device wherein an electronic circuit is designed to work in two alternative modes: an air shot mode and a dose injection mode. When working in the air shot mode a small predetermined air shot dose is pressed out from the ampule when the injection button is actuated. When working in the injection mode, a dose set by operation of the dose setting means is injected by operation of the injection button. The electronic injection device is normally working in the air shot mode but shifts to work in the dose injection mode when it receives a signal indicating that the dose setting means has been operated. The circuit returns to its air shot mode when receiving a signal indicating that the set dose has been injected. This signal can originate either from a switch indicating that the protection cap is mounted or from a switch indicating that the injection button has been pressed.

  • Patent number: 6484525
    Abstract: A first channel (20) is formed by sequentially connecting a compressor (21), a vapor separator (55), a heat exchanger (30) and an expander (22). In the first channel (20), a room air is taken as a primary air and discharged to outdoors. A second channel (40) is formed by connecting a heat exchanger (30) to a second inlet duct (43) and a second outlet duct (44). In the second channel (40), an outside air is taken as a secondary air and supplied to a room. The vapor separator (55) is connected to a vacuum pump (36). The vapor separator (55) separates vapor from the compressed primary air to dehumidify the primary air to or below the absolute humidity of the outside air. The vapor separated by the vapor separator (55) is partly supplied to the secondary air in the second outlet duct (44). Then, the secondary air thus humidified is supplied to the room.

  • Patent number: 6471098
    Abstract: The invention is related to the structure of an adhesive dispenser that is composed of an outer tube with a push rod and a handle. The apparatus uses a certain number of elastic elements to make relative displacement between push rod and outer tube, while it uses the locking end of the push rod and cotter groove to perform functions like locating, acceleration and stepwise movement, which makes easy operation for the users. Moreover, in the apparatus the outer tube can be equipped with an inner tube. So the spacing between inner tube and outer tube provides a mechanism that the sealant and adhesive filled in-between the inner and outer tube will flow out and mix under the motion of the push rod. This mechanism will not only facilitate sealing, adhesion and hardening prevention, but will also provide reusability.
