Granted: 2002-03-26
Abstract: Method and apparatus for test-ing the qualitative susceptibility of a microorganism to growth inhibition by an antimicrobial product utilizing a test panel. (100-1). Test modules (107, 108, 109) are carried in a negative growth control well (101), positive growth control well (102), and a test well (103). The test modules comprise a   dry solid volume of a subset of the con-stituents of a set of test chemicals com-prising resazurin and growth medium. The test module (109) in the test well further comprises a volume of antimic-robial product. The test module (107) . in the negative growth control well is rehydrated by a volume of sterile liquid (110) containing all of the other test chemicals not present in the test mo-dune. The test modules (108, 109) in the positive growth control well and in the test well are rehydrated by a volume of inoculum liquid (112, 113) containing all those other constituents together with a concentration of microorganism. The test panel (100-1) is incubated and then read using a visible light reading protocol or a fluorescence excitation reading protocol to determine growth or no growth in the wells. The visible light reading protocol determines organism growth by presence of a color shift from blue toward red. Test modules are preferably paper disks with test constituents absorbed therein and the concentration of antimic-robial product printed thereon.

Title: Turbocharger assembly and stabilizing journal bearing therefor
Inventor: BLASE JAMES L
IPC: F02B3/06
Filed: 1991-08-12
Granted: 1995-01-17
Abstract: An engine turbocharger, particularly of the two cycle diesel type for railway locomotives and other applications, has a rotor with an overhung compressor supported by a compressor journal bearing and thrust flange combination.  The bearing combines a multi (two) lobed offset cylindrical wedge film inner surface with a close clearance squeeze film outer surface that causes the bearing to float laterally in a support member to damp shaft runout while supporting the rotor on load controlling oil wedges.  The fixed flange provides thrust control and provides a loose pin connection with the bearing that prevents rotation while permitting its squeeze film damping lateral motion.  Particular pressure lubrication means provide oil to the bearing interior and exterior adequate for the oil wedge supporting and squeeze film damping functions.

Patent CA-2071592-C (CA)
Title: Magnetic head driving circuit
Inventor: FUJI HIROSHI
IPC: G11B11/105
Filed: 1992-06-18
Granted: 1997-02-11
Abstract: In a magnetic head driving circuit according to the present invention, switching devices are turned on/off in response to a recording signal, thereby inverting a drive current to be applied from direct current power sources to a magnetic head coil. Switching devices are connected in parallel with dummy loads serially connected to the direct current power sources. In response to theswitching of the switching devices, the magnetic head coil and a dummy load alternately function as a load of each auxiliary coil. The impedance of each dummy load is set to be equal to the impedance of the magnetic head coil, thereby fixing the total load of each of the auxiliary coils at any time. Since a balance can be established between a value of a drive current in one direction and that of a drive current in the opposite direction, it is possible to reduce jitter of a recording mark and provide abrupt rises and falls in the drive current.

The latch is released upon first pushing the stylus and then releasing it. Biasing means engages the stylus and moves it against the keeper and ejects  the  stylus  outwardly  from  the  storage  compartment allowing the stylus to be grasped and withdrawn from the tablet. The storage compartment is open at opposite ends and has two cams, one at each end of the compartment so that the stylus, at the convenience of the user, can be inserted into either end for storage.

Title: Varying tone security document
Inventor: MOWRY WILLIAM H JR
IPC: G03C5/08
Filed: 1993-12-30
Granted: 1998-10-06
Abstract: An improved security document according to the present invention includes a substrate having a surface for carrying indicia.  The document has background printed matter, consisting of a pattern of elements of a first size and frequency, printed at a first density on the surface.  The document further has a cancellation term, consisting of a pattern of elements of a second size and frequency, printed at a second density on the surface.  Elements of one of the first size or the second size are sufficiently small such that they are not reproduced by a color copier at a particular copier setting, and elements of the other of the first size or the second size are sufficiently large such that they are reproduced by the color copier at the particular copier setting.  As a result, a copy of the security document made on a color copier displays the cancellation term. At least a portion of the security document surface is divisible into a plurality of bands extending across the surface.  The sizes of the elements and the density of the background printed matter and the cancellation term vary together across the bands in a direction generally normal to the bands.  As an alternative, the frequencies of the elements may vary across the bands such that the density of the background printed matter and the density of the cancellation term are changed.  Such a document may be printed with different colors of ink on different portions of the document, and with the bands in which a color transition occurs being printed with two colors of ink at differing screen angles.

Title: Traffic management in packet communications networks
Inventor: GUN LEVENT
IPC: H04L12/56
Filed: 1994-04-05
Granted: 1999-07-13
Abstract: In a packet communications network, the addition or deletion of a connection to the network by a user is governed by a link traffic metric which represents the effective capacity of each link in the network which participates in the packet connection route. A new connection (or deletion) is represented by a compatible metric which allows updates in the link metric by simple vector addition or subtraction. Separate link metrics for a plurality of classes of service permit a much higher efficiency in the exploitation of the link bandwidth than is possible with a single link metric. A packet network using multiple link metricsand efficient metric updating techniques provides increased packet throughput while, at the same time, preserving all class of service guarantees.
