Patent number: 6817280Abstract: Systems and methods for brewing beverages in accordance with the present invention can improve the flavor of brewed beverages and reduce the vertical space required for a system using suction. One such assembly comprises a brewing chamber adapted to hold a filter having an intake duct for receiving fluid for brewing, and an output duct for expelling a brewed beverage. The brewing chamber is positioned above a pressurizable container, or carafe, having an adjustable standpipe and containing the fluid. The carafe has a heated base, which when heated causes pressure to build up, forcing the fluid up the standpipe, through a check valve, through the intake duct and into the filter. Once substantially all of the fluid has been urged into the brew chamber, the heat is removed, creating a partial vacuum that pulls the brewed beverage back into the carafe. This description is not intended to be a complete description of, or limit the scope of, the invention.Type: GrantFiled: March 18, 2003Date of Patent: November 16, 2004Assignee: BrewBot, Inc.Inventors: Robert C. Hall, Gary L. Waymire, Michael R. Barry, Shane Washburn

Patent number: 6197001Abstract: The present invention is directed to a vascular access device for introducing a catheter in a blood vessel using a guide advancing mechanism. The device generally comprises a housing, an introducer needle, a catheter, a guide wire and an actuating means. The introducer needle of the vascular access device is used to penetrate the blood vessel. The actuating means is then initiated and the guide wire is steadily propelled into the blood vessel. Once the guide wire is in place, the catheter, which is concentrically placed over the introducer needle and guide wire, is uncoupled from the vascular access device and guided into the blood vessel by the guide wire.Type: GrantFiled: September 27, 1996Date of Patent: March 6, 2001Assignee: Becton Dickinson and CompanyInventors: Jay Wilson, Shawn Hanna, Jeff Chen, Robert C.

Patent number: 6139903Abstract: A method of controlling and operating a fluid dispensing apparatus is provided which modifies a tool speed signal from a robot and generates a corrected signal to a dispenser nozzle flow controller to compensate for non-linear flow characteristics of fluids, such as non-Newtonian adhesive fluids, to maintain uniform bead size as the tool speed varies. The corrected tool speed signal is generated by computing the ideal flow for the tool speed, comparing the computed flow with actual flow data stored in memory using linear interpolation of data between the stored values, and generating a control signal modified in accordance with the comparison. The stored data is acquired by operation of the apparatus in a calibration mode wherein a series of standard signals is sent to the fluid controller while the actual flow at each signal level is measured and stored in a table. The method corrects for non-linear flow phenomena such as that known as the shear-thinning effect that is flow rate dependent.Type: GrantFiled: September 24, 1992Date of Patent: October 31, 2000Assignee: Nordson CorporationInventors: Carl N. Baron, Stephen L. Merkel, Robert C. Hall

Patent number: 5995909Abstract: A fluid dispensing control for controlling the dispensing of a fluid by a metering valve through a nozzle onto a workpiece. An initial value of a flow characteristic of the fluid is determined that is correlated to the relationship between the flow rate of the fluid and nozzle pressure. Desired nozzle pressure values are periodically determined by evaluating a model of flow rate of the fluid through nozzle in response to the initial value of the flow characteristic and a desired flow rate value. Thereafter, the control provides command signals to the metering valve as a function of the desired nozzle pressures. A new value of the flow characteristic is determined as a function of the measured volume of fluid dispensed during the dispensing cycle to the measured nozzle pressure. During a subsequent dispensing cycle, the control determines the desired nozzle pressures by evaluating the model of flow rate of the fluid through the nozzle as a function of the new value of the flow characteristic.Type: GrantFiled: November 24, 1998Date of Patent: November 30, 1999Assignee: Nordson CorporationInventors: Carl A.

Patent number: 5114752Abstract: A method for depositing liquid material onto a workpiece in the form of a deposit having a desired conformation wherein the material is discharged under pressure from the nozzle of a dispensing gun which can be manipulated by a robot to lay the deposit according to a programmed pattern on the workpiece. One or more gas jets are directed toward the material after the material is discharged from the nozzle to impart a desired conformation to the material deposited on the workpiece. The flow rate of the gas jets is controlled in accordance with the liquid flow rate to maintain substantial uniformity of the conformation of the deposit. The flow rate of the gas jets may also be controlled with reference to a tool speed signal which varies according to the relative speed between the nozzle and the workpiece as well as an auxiliary signal the latter of which can be used to selectively alter the conformation of the deposit.Type: GrantFiled: December 21, 1990Date of Patent: May 19, 1992Assignee: Nordson CorporationInventor: Robert C.

Patent number: 4674706Abstract: A projectile having a streamline assembly which includes a frusto-conical saddle secured to the boattail area of the projectile bullet, a carrying cylinder having one end secured to the saddle, with multiple, concentrically oriented, tapered, collapsible rings normally located inside the opposite end of the carrying cylinder and biased against a pressure disk fitted against the opposite end of the carrying cylinder, wherein firing of the projectile causes the pressure disk to tear away from the carrying cylinder and deploy the collapsible rings outwardly of the carrying cylinder and behind the bullet in a "beehive" configuration, to reduce air resistance as the projectile moves through the atmosphere. In a preferred embodiment the pressure disk is pressed against the carrying cylinder by means of a brass screw, the threads of which engage an aperture in the saddle and are stripped from the brass screw to release the disk when the projectile is fired.Type: GrantFiled: February 21, 1986Date of Patent: June 23, 1987Inventor: Robert C.
