Title: Bias current control for providing accurate potentiometric measurements
Inventor: MCKEE CHARLES B JR
IPC: G01N27/416
Filed: 1990-05-15
Abstract: ABSTRACT    Apparatus  and  method  are  provided  to  ensure accuracy  of  a  measurement  signal  obtained  using  a potentiometric  sensor  placed  in  a  solution.    The apparatus includes an interface amplifier that generates a relatively large turn-on bias current whenever the amplifier  is  initially  powered  on.     To  avoid polarization of the potentiometric sensor by the turn-on bias current,  a switch device is used to direct the turn-on  bias  current  along  a  path  away  from  the potentiometric sensor.  The switch device is controlled using a timer circuit that causes a change in position of the switch device after a predetermined time delay. During the time delay, the bias current reduces to a normal  value  and  polarization  of  the  potentiometric sensor has been avoided.  An accurate measurement of a physical parameter associated with the solution can then be taken without the detrimental effect of the turn-on bias  current  on  the  potentiometric  sensor.    The apparatus  has  particular  utility  in  obtaining water quality data, such as hydrogen potential, specific ion potential and oxygen reduction potential.

IPC: B65B7/28
Filed: 1990-05-15
Abstract: ABSTRACT OF THE DISCLOSURE      An automatic lid dispensing and applicator arrangement for an automated drinkmaker machine.  The lidding arrangement automatically separates lids from a stack of lids and applies the separated lids onto cups.  A large supply of lids is maintained in a rotatable lid supply carousel which periodically resupplies lids to a lid dispenser which supports a stack of lids to be dispensed.  A lid shuttle is positioned adjacent the bottom of the lid dispenser, and is supported for linear translating and reciprocating movement between retracted and extended positions.  The lid shuttle supports a lid engaging member designed to engage a first bottommost lid of the stack of lids and to retain the first bottommost lid in a first intermediate position in the lid shuttle while the lid shuttle is moved in translation to its extended position. The lid shuttle is then moved in translation to its retracted position, during which the first lid is moved within the lid shuttle to a second loaded position therein beneath a lid applicator supported by the lid shuttle.  The lid shuttle is then moved to its extended position, during which the first lid remains in the second loaded position while the lid engaging member simultaneously engages a second bottommost lid of the lid stack and retains the second lid in the first intermediate position in the lid shuttle.  The lid shuttle is then moved in translation to its retracted position, during which the lid applicator presses and applies the first lid onto a cup positioned therebeneath, and the second lid is moved within the lid shuttle to the second loaded position.  The cycle is then repeated for subsequent lids during linear translating and reciprocating movements of the lid shuttle.

Patent CA-2021397-A1 (CA)
Inventor: JONES JEFFREY A
IPC: F16K31/524
Filed: 1990-07-18
Abstract: A multi-port valve internally supports a rotatable trunnion having an elbow passage between a nozzle portion of the trunnion and a lower end outlet that communicates with a test port of the valve body. The outer end of the nozzle has an axially reciprocable hollow seal piston with a seal support ring whose outer face is formed with an endless groove to receive an O-ring. An actuating shaft is coaxially mounted in an upper end of the trunnion and has a lower end with an eccentric pin engaged in a slot of the seal piston to reciprocate the seal piston into and out of sealing registration around a port selected by rotation of the trunnion. External ends of the actuating shaft and trunnion are respectively drivably coupled to a coaxial sprocket wheel and geneva wheel. A housing on top of the valve contains an input rotor fitted with a cam and a drive roller for engaging radial slots of the geneva wheel alternately with cam engagement of the dwell notches of the geneva wheel.      Concurrently and in advance of forward rotation of the geneva wheel, a rotor driven seal actuating yoke at a free end engages one of a series of radial slots of the sprocket to rotate the sprocket in a retrograde direction to disengage the seal. When the yoke is disengaged, a decent mechanism temporarily locks the geneva and sprocket wheels together for co-rotation in a forward direction as the geneva drive roller again comes into engagement with the geneva wheel. After the nozzle has been advanced one step, further rotation of the input rotor advances an arm independently pivotally mounted on the yoke to compress a spring mechanism to bias the yoke and sprocket to compress the seal on a seat around the next port.

Title: Method and apparatus for determining anaerobic capacity
Inventor: YORIOKA GERALD N
IPC: A61B5/22
Filed: 1990-08-08
Abstract: A method and apparatus for defining and determining a value for an anaerobic capacity parameter is disclosed. The anaerobic capacity parameter is defined as the time required to completely deplete the subject's anaerobic capacity given maximum mechanical exertion by the subject under controlled conditions. A value for the anaerobic capacity parameter for a subject is generated via a testing system. The testing system includes an exercise device (12), a power characteristic sensor (14), and a processing unit (16). The exercise device (12) includes a movable component, the movement of which can represent a measurement of distance. The exercise device creates a load on the subject. The power characteristic sensor (14) is used to sense the movement of the movable component and the load imposed on the subject. Power characteristic data, e.g., movement and load data, are generated by the power characteristic sensor. The processing unit (16) is connected to the power characteristics sensor (14) such that power characteristic data and control signals are transferred therebetween. The improvement in the testing system is the inclusion of a main control program in the processing unit (16). The main control program controls the recording of power required to move the movable component is derived from the power characteristic data over a test period. A set of power values indicative of the power required to move the movable component is derived from the power characteristic data. An anaerobic capacity value is determined by analyzing the logarithmic decay of the derived power values. The time to completely deplete a logarithmic function approximating the derived power values is the anaerobic capacity value. Values for parameters such as will power, total power, and power potential are also derived from the analysis.
