Title: Liquid dispensing and suctioning system for surface cleaning
Inventor: MILLER JONATHAN
IPC: A47L7/00
Filed: 1990-06-07
Granted: 1995-05-23
Abstract: Dispensing within a liquid dispensing and suctioning system is controlled by pinching a flexible tube with a spring-biased actuator. The system includes a slidable extension for pulling the actuator to open the tube to dispense liquid to a surface to be cleaned.  The system is assembled with a tubular wand of a wet/dry suctioning system.  The liquid dispensing outlet from the system is a slot from which liquid exits.  That outlet slot is disposed near to the suction inlet slot of the suctioning system.  A rib which is located between the dispensing outlet and the suction inlet contacts the surface being suctioned for assuring that liquid reaches that surface and is not sucked up in the suction nozzle inlet reaching the surface.

Patent CA-2025330-C (CA)
Inventor: OSTEN DAVID W
IPC: G01N33/72
Filed: 1990-09-13
Granted: 2002-01-22
Abstract: A method is provided for predicting a property of a matter of biological origin, such as biological fluid, containing water, in a dynamic condition where the biological fluid may be approximated to contain two compartments where one compartment has a proportionally larger or smaller amount of water than the other compartment having the property of interest. The method involves establishing a training set in the near-infrared (NIR) region with independent quantification of the property of the fluid using known techniques. The training set is mathematically analyzed according to a correlation developed by regression analysis after employment of a pre-processing technique such as a multiple derivative transformation of spectra or a ratioing of two wavelengths in the spectra. The result is a mathematical transformation equation which quantitatively relates spectral intensities at specific wavelengths to the property of interest. This transformation equation may be applied to unknown samples so as to predict their properties, thereby eliminating need for the reference method except for validation or recalibration. The method provides rapid and accurate prediction of the property of the unknown sample, which may be the property of hematocrit or hemoglobin concentration in whole animal blood. Other analyses of properties in the biological fluid such as oxygen saturation in hemoglobin in whole animal blood may be included in the mathematical analysis to further refine the prediction of the property of interest. Also, a loop from the patient is disclosed for the purpose of monitoring the property of interest nearly simultaneously with changes in that property of interest.

Title: Ptc composition by grafting method
Inventor: OHKITA KUMAKAZU
IPC: C08K3/04
Filed: 1990-12-21
Granted: 1995-08-22
Abstract: A   process   for   producing   PTC   (positive temperature  coefficient)   self-resetting   overcurrent protection  elements  using  two  different  crystalline polymers with an organic peroxide and carbon black.  The mixture is kneaded at an elevated temperature.  The two crystalline polymers  include different proportions  of tertiary hydrogen atoms to carbon atoms,  so that the desired  PTC  characteristics  of  a  highly  crystallized polymer can obtain the benefit of greater proportions of tertiary hydrogen in a less highly crystallized polymer. A high degree of grafting to carbon black that increases the number of polymer radicals in the crystalline polymer mixture through the decomposition of organic peroxide. The resulting mixture tends to disperse the carbon black uniformly  throughout  the  resulting  mixture,  and  to position the carbon black in a three-dimensional matrix in which  it  is  fixed  by  cross-linking.    The  uniform distribution of the carbon black reduces localized heating and thus minimizes resistance changes following repeated overcurrent conditions.

Title: Cordless key telephone system capable of quickly answering incoming calls
Inventor: SAEGUSA NOBORU
IPC: H04W84/16
Filed: 1991-04-16
Granted: 1995-02-07
Abstract: In a cordless key telephone system, access units are located in groups corresponding to service areas for broadcasting radio signals on a control channel or on an assigned speech channel to cordless stations. A main controller selects one of the access units for each service area in response to an incoming call from the switched telephone network and sends a first alert signal to the selected access units to cause them to broadcast a recurrent sequence of second alert signals containing the identifiers of standby cordless stations. The second alert signal is received by each standby cordless station and an ACK signal is transmitted if the received signal contains its identifier. The ACK signal is copied by each access unit for transmission to the main controller, whereupon it returns a proceed-to-assign signal if the number of the received copies of the ACK signals is equal to the number of all standby stations. The proceed-to-assign signal is received by the selected access units and a channel assignment signal is broadcast indicating the assigned channel. On receiving it, each station is switched to the assigned channel and one of the stations in each area transmits an end-of-switching signal to cause the access units to broadcast ringing signals containing the identifiers of the alerted stations. In response to a given cordless station going off hook, an off-hook signal is sent from it and copied by the associated access unit for transmission to the main controller, which returns a turn-on signal to allow the given station to activate its speech circuit.
Patent CA-2049544-C (CA)
Title: Logarithmic amplifier/detector delay compensation
Inventor: DENT PAUL WILKINSON
IPC: H03G7/00
Filed: 1991-08-20
Granted: 2000-11-07
Abstract: An amplifier/detector chain logarithmically amplifies an input signal as well as compensates for delays generated by necessary bandwidth restrictions. A plurality of amplifiers are connected in series and grouped in amplifier stages with each stage having at least one amplifier. In between each amplifier stage is a filter which restricts the bandwidth of signals to frequencies in a desired signal range. When an amplifier stage includes more than one amplifier, a local summer sums the outputs detected by detectors associated with each amplifier in a particular stage. When an amplifier stage includes only a single amplifier associated detector, the local sum signal for the stage is simply the detector output. No local summer is required. Because of the time delay introduced by each interposed filter, each local sum is input to a corresponding compensating device which compensates for the associated time delay. Each compensating device stores its corresponding local sum until the local sum from the final stage is ready to be output. When all of the local summer outputs have been time-aligned or brought in phase, the local sums are connected from their corresponding compensating devices to a central summer stage. The output of the central summer represents the instantaneous output of the logarithmically amplified input signal.
