Patent CA-2161383-A1 (CA)
Inventor: GREER DAVID A
IPC: A61B5/0432
Filed: 1995-10-25
Abstract: An event history data recorder and method for recording data relating to a distinct event and pertaining to operation of a mechanism preceding and following each occurrence of such distinct event.    The  recorder comprises  a means  for  collecting  data pertaining to such operation and for formatting such collected data into a sequence of data elements.  The recorder includes a circular buffer  linked  to  the  collecting  and  formatting  means  for temporarily storing a preset number of the data elements.  The data elements are continuously stored on the circular buffer as a newest data element continuously writes over an oldest data element as a storage limit of the circular buffer is reached.  The recorder also includes a timer of predetermined duration which activates upon each occurrence of such distinct event.  The recorder additionally includes a memory device for retaining the data elements.  The data elements can be accessed therefrom for analysis of such operation of such mechanism surrounding such distinct event.  The recorder further includes a means, connected to the timer, for transferring the data elements from the circular buffer to the memory device wherein for each occurrence of such distinct event a preselected number of the data elements stored prior to, and including, an instant the timer deactivates is transferred by the transferring means from the circular buffer to the memory device.  A data log is thereby  formed within the memory device  from which  the  data elements may be accessed for analysis of such operation of such mechanism.

Patent CA-2166006-A1 (CA)
Inventor: BARKENHAGEN MICHAEL E
IPC: A61B3/10
Filed: 1995-12-22
Abstract: The body chemistry of a person is determined by directing a beam of light into the eye (28) of the person, measuring the spectral response of the eye to the beam of light, comparing the measured spectral response to a standard spectral response, and forming a conclusion as to the chemistry of the body from the comparison. The light selected for the measurement does not harm the eye (28), and is preferably in the ultraviolet or infrared ranges.      The response of the eye (28) chosen for measurement is that of reflected, fluoresced, or scattered light. It is preferred to use two or more of these techniques simultaneously, to minimize the likelihood of error. The comparison is made by comparing the measured response of the eye (28) to a standard response from a library of previously established responses.

Title: Signal-receiving and signal-processing unit
Inventor: HEDBERG MATS OLOF JOAKIM
IPC: G05F3/26
Filed: 1995-03-20
Abstract: The present invention comprises a signal-receiving and signal-processing unit connected to one or several conductors adapted to transmit information-carrying signals in the form of voltage pulses.  A conductor is connected to a transistor belonging to a signal-receiving circuit, to have an effect upon a current by using variations in the voltage pulses and the voltage value of a pulse.  The current is in the form of pulses passing through the transistor.  The current is generated by the voltage pulse variations and a voltage level, and the current is adapted to an information-carrying form in a signal-processing circuit.  The transistor belonging to the signal-receiving circuit is coordinated with at least one other transistor to form a current mirror.  The ability of the signal-receiving circuit to receive, detect, and process the signals is adjustable through a current-generating circuit such that an increasing current value provides detection of a voltage pulse at an increased transfer rate and vice versa.

Inventor: GESTERMANN FRITZ
IPC: C01B7/04
Filed: 1996-09-23
Abstract: In the process for working up the reaction gas consisting of chlorine, hydrogen chloride, oxygen and water vapour produced in a chlorine reactor, the reaction gas leaving the reactor 1 is first cooled until the water of reaction and hydrogen chloride condense in the form of concentrated hydrochloric acid. The concentrated hydrochloric acid is then separated from the reaction gas in a phase separation column 3 and discharged. The remaining reaction gas, from which the substantial proportion of the water and a proportion of the hydrogen chloride has been removed, is then post-dried in a drying tower 6. The post-dried reaction gas consisting of chlorine, oxygen and hydrogen chloride is then compressed to 1 to 30 bar by a compressor 7. In the subsequent stage, the compressed reaction gas is passed through a cooled chlorine recuperator 8, wherein the chlorine is very largely liquefied. Finally, the components of the reaction gas which could not be condensed in the chlorine recuperator 8 are at least partially returned to the reactor 1.
