摘要:
A screen closure for a garage doorway has a plurality of screened panels movable from an elevated, stored position in which such panels are side-by-side to an extended, operative position in which the panels extend vertically a distance sufficient to close the doorway. Those panels which are at eye level and below when the panels are in their extended position are substantially coplanar.

A high pressure liquid chromatography (HPLC) capillary column device, system and method for processing a HPLC sample with a cartridge housing a packed capillary column; at least one inlet connection to the capillary column for a sample fluid; and at least one outlet connection from the capillary column for the sample fluid. The outlet connection is able to accommodate either a spray tip for atomizing the sample fluid or a transport tube for transporting the sample fluid from a spray tip column to a spray tip. Inlet connections enable supply of electrical power to the capillary column through electrical connections disposed within the cartridge housing; and gas for evaporating the sample liquid is supplied to at least one outlet connection from the capillary column for the sample fluid through a gas supply line within the cartridge housing. The temperature of the sample liquid can be controlled through a heat connection.

A method of cutting an elastomeric strip of material is described. The method includes the step of advancing a strip of material 2 a predetermined distance by a conveyor means 30. Resisting reverse movement of the strip 2; tensioning the strip 2; and cutting simultaneously across the entire width of the strip 2 through the thickness of the strip 2 on a skive angle of 45 degrees or less preferably about 28 degrees to form a cut length of material thereby relaxing the tension in the strip as the skive cut ends 3 and 4 move apart. This method of cutting can be accomplished by providing an apparatus 100 for cutting an elastomeric strip of material 2 which has a frame assembly 50, a motorized feed conveyor 30 mounted onto the frame 50 for advancing the strip material 2, a cutter assembly 20 mounted on the frame assembly 50 including a guillotine cutter 22 oriented to move along a skive angle α, a second conveyor means 40 for supporting the strip 2, the second conveyor means 40 having rollers 42 having a one way directional movement in the forward direction resistant to movement in the reverse direction; a motor 32 connected to the feed conveyor 30 to drive the conveyor 30 in an advancing direction and having a reverse tensioning direction; and wherein the cutter assembly 20 is positioned between the second conveyor means 40 and the feed conveyor 30 to cut the strip 2 after a tension is applied to the strip by reverse motion of the feed conveyor 30.
摘要:
A method, system and apparatus for the monitoring, diagnosis and evaluation of the state of a dynamic system is disclosed. This method and system provides the processing means for receiving sensed and/or simulated data, converting such data into a displayable object format and displaying such objects in a manner such that the interrelationships between the respective variables can be correlated and identified by a user. This invention provides for the rapid cognitive grasp of the overall state of a critical function with respect to a dynamic system. The system provides for displayed objects, which change in real-time to show the changes of the functions of the system. It is a highly flexible system which works with a wide variety of applications, including biological systems, environmental systems, engineering systems, economic systems, mechanical systems, chemical systems and the like. In particular, this invention is directed to the processing and display of drug data for the use of doctors in the process of monitoring or administering drugs to patients.
摘要:
A method for coordinating outbound and inbound itineraries for a plurality of travelers is provided. Such a method comprises receiving a destination location, a plurality of origin locations, and travel information, wherein each origin location is associated with at least one traveler. A set of suggested outbound and inbound itineraries between each origin location and the destination location is then determined, based upon the travel information, from a travel database comprising at least outbound and inbound itineraries between the origin locations and the destination location, wherein each suggested outbound and inbound itinerary comprises an arrival time and a departure time with respect to the destination location, and the set of suggested outbound and inbound itineraries collectively provides an optimal time together of the travelers at the destination location. Associated systems and methods are also provided.
摘要:
An optically controlled switch includes first and second electrodes, a channel extending between the electrodes, and a light source positioned to illuminate the channel. The light source produces a wavelength capable of changing the material's conductivity. The channel includes a photosensitive organic material and is configured to operate as a light controlled switch.
摘要:
An apparatus for displacing an article including first and second pallets for holding and transporting an article between two process stations; an H-bar assembly for receiving the first and second pallets at one of the two process stations; wherein, in operation, a process is performed on the articles while the first and second pallets are received by the H-bar assembly, the pallets then being transported to the second process station where a second process is performed on the articles.
摘要:
A reciprocating four-stroke internal combustion engine includes a variable exhaust valve operating system for changing the duration of an exhaust valve opening event and also a camshaft drive for rotating a valve operating camshaft and adjusting the rotational timing of the camshaft with respect to the crankshaft.
摘要:
A reciprocating internal combustion engine has at least one camshaft for actuating intake and exhaust valves and a camshaft drive for rotating the camshaft and for adjusting the rotational timing of the camshaft with respect to the crankshaft. A charge motion control valve and the variable camshaft timing mechanism are both used to selectively impart angular momentum to charge entering the engine's cylinder(s).
摘要:
A temperature compensated doctor blade system is disclosed for controlling the amount of liquid on a substrate. Variation in temperature is found to cause wide variation in liquid viscosity which affects doctor blade pressure requirements. An expandable chamber containing a temperature responsive fluid is used to control the pressure applied to a flexible doctor blade.
