Patent CA-2124485-A1 (CA)
Inventor: HWANG SHYSHUNG S
IPC: G03G15/10
Filed: 1994-05-27
Abstract: An apparatus in which an electrostatic latent image is developed with liquid toner. The apparatus has a liquid extruder that extrudes a thin film of liquid toner which is attracted to the electrostatic latent image forming a liquid image on a photoconductive surface. The extruder is electrically biased to a suitable magnitude and polarity to ensure that the liquid toner is attracted to the latent image. A vacuum is applied on the liquid toner as it is being attracted to the latent image so as to reduce the thickness of the layer coated thereon.

Title: Autorate method for simultaneous transmission of voice and data
Inventor: BREMER GORDON
IPC: H04L1/00
Filed: 1994-06-09
Abstract: Abstract of the Disclosure In a simultaneous voice and data communications system comprising two modems, an autorate feature is implemented in one illustrative method by adding a silence detector to the receiver circuitry of at least one of the modems in such a way that noise statistics for the communications channel are only accumulated during intervals of silence. If the resulting noise statistics exceed a predetermined threshold, i.e., the communications channel is too noisy, the receiving modem negotiates a lower data rate with the transmitting modem. In another illustrative method, the transmitting modem provides a signal, which represents an interval of silence, to the receiving modem. Upon receipt of the signal, the receiving modem accumulates error statistics in order to determine if the communications channel is too noisy.
Patent CA-2125806-A1 (CA)
Inventor: FOX DAVID
IPC: G06F19/00
Filed: 1994-06-14
Abstract: The buttonless memory system of the present invention retrieves and stores the measurement results of a sample for the user of an electronic measurement device, particularly a portable and personal electrical measurement device, with minimal user interaction.  The user simply activates the portable measurement device and waits as the buttonless memory system initially cycles through the stored measurement results.  The buttonless memory system stops retrieving from memory when the measurement device detects a sample or control solution.  After test measurement of the sample, the user can choose to store the measurement result by deactivating the measurement device during the time the memory display is on.  If the sample is a control solution, the user can delete the measurement result from memory by waiting and deactivating the measurement device after the memory display is off.  In this way, the buttonless memory system provides a simple and effective memory management scheme for measurement devices.

Title: Analytical element, composition and method using modified apo-horseradish peroxidase
Inventor: SNOKE ROY EUGENE
IPC: G01N33/543
Filed: 1995-07-17
Abstract: Modified apo-peroxidases have been found useful in analytical methods to remove the bias caused by the presence of hemoglobin in the test specimens.      While apo-peroxidases are known to remove serum interferents, they fail to overcome the hemoglobin bias, particularly when dry coated analytical elements are used in the assays. Blocking the nitrogen atoms of the imidzolyl groups of the histidine amino acids of the apo-peroxidase prevents catalytic activity of the protein in the presence of hemoglobin.

Title: Switching device
Inventor: NIEMEYER LUTZ
IPC: H01H33/14
Filed: 1995-01-16
Abstract: The  device  for  switching  electrical  current contains  a  compressed  gas-blast  circuit-breaker,  at least one vacuum circuit-breaker (14) and two current connections (2, 3).   In this switching device, a first erosion contact  (10)  of  the  compressed  gas-blast circuit-breaker is electrically conductively connected to a stationary electrode (15) of the vacuum circuit-breaker  (14),  a  second  erosion  contact  (7)  of  the compressed  gas-blast  circuit-breaker  is  electrically conductively connected to a first current connection (2) of the two current connections (2, 3) and a movable electrode  (16)  of the vacuum circuit-breaker  (14)  is electrically conductively connected to a second current connection (3) of the two current connections (2, 3), thereby forming an extinction current path.   The two electrodes (15, 16) of the vacuum circuit-breaker (14) can be  separated from one another without using the drive  (5) and receive a contact pressure force which prevents  the  separation  of  the  electrodes  (15,  16) below a limit value of the current to be disconnected.    During  switching  off,  the  current  to  be disconnected is commutated from a rated current path, which contains two rated current contacts  (8,  11)  of the  compressed  gas-blast  circuit-breaker,  into  the extinction current path running in parallel therewith. The vacuum circuit-breaker (14) which is now situated in the extinction current path is only opened when the current to be disconnected exceeds the abovementioned limit value.        Since the vacuum circuit-breaker  (14)  carries no rated current and,  in contrast to the compressed gas-blast circuit-breaker, participates only in a few disconnection  operations,  it can be  dimensioned  for considerably lighter duty than a vacuum circuit-breaker which  carries  rated  current  and  is  actuated  during every switching operation.
