Patent CA-2082013-A1 (CA)
Title: Mechanical Gas Chromatography Injection Valves and Column Multiplexing Techniques
Inventor: SACKS RICHARD D
IPC: G01N1/22
Filed: 1992-11-03
Abstract: Several  embodiments  of  gas  chromatography  systems  are disclosed incorporating mechanical sample injection valves.  The injection valves incorporate a delivery tube having an outlet which is swept past the inlet of a separation column to provide a short duration inlet plug into the separation column.  Carrier gas and sample gas flow is managed through the valve to prevent inadvertent injection after an injection is desired and to assure that  the  sample is  not  contaminated  by past  sample  flow.          Embodiments of injections valve are described for providing inputs into several gas chromatography columns.  In addition, a gas chromatography system is described in which multiple columns are used which are time multiplexed with a single detector to produce a complex combined chromatogram from the plural columns.          By appropriate selection of column characteristics and injection sequence, the resulting chromatogram can provide an overlay of chromatograms  which  provide  good  resolution  of  all  the constituents of the mixture of interest within a short analysis time.

Title: Rain belt
Inventor: MCQUOID SEAN W
IPC: A41D3/04
Filed: 1993-09-13
Abstract: ABSTRACT The "Rain Belt" is a simple roll-up rain jacket, skirt, or full rain coat. The belt consists of two long soft pouches, held together by an adjustable buckle and strap.  Each pouch has a zipper running lengthwise lengthwise which holds the contents inside when not in use.  Each pouch can be opened separately to allow the "Rain Belt" to be used as either a jacket or a skirt.  If both pouches are opened ,then the "Rain Belt" becomes a full raincoat.  The material recommended for the jacket and skirt is waterproofed nylon.  The zippers and the buckle should be plastic and the pouches could be made from nylon.  This would keep the belt light and rust proof.  The jacket and skirt could be held together with velcro patches.  If the colours and the designs of the nylon were varied, the the belt could be very conservative or quite creative.

Inventor: YOKOMURA RYOUJI
IPC: H04L27/22
Filed: 1993-07-29
Abstract: ABSTRACT OF THE DISCLOSURE     A frequency stabilizing circuit for a .pi./4 QPSK (Quadrature Phase Shift Keying) signal receiver has a voltage controlled oscillator (VCO) for outputting an oscillation signal whose frequency changes in response to a control voltage applied to the VCO. A mixer changes the frequency of an input .pi./4 shift QPSK signal. A counter measures the frequency of the .pi./4 shift QPSK signal from the mixer. A timing generator generates, on the basis of the oscillation signal from the VCO, a timing indicative of an interval during which the counter is to measure the frequency. A set data generator generates a frequency signal having a predetermined set frequency. A comparator compares the frequency measured by the counter and the set frequency of the set data generator to thereby output the resulting frequency deviation. A voltage data generator changes voltage data in association with the frequency deviation. A digital-to-analog converter transforms the voltage data to the control voltage. A demodulator demodulates the .pi./4 shift QPSK signal from the mixer. An integrator adds up phase s h i f t s output from the demodulator over the interval generated by the timing generator. An adder/subtracter selectively increases or decreases the set frequency of the frequency signal output from the data generator in association with a cumulative phase shift produced by the integrator. The circuit is capable of stabilizing the frequency of a .pi./4 shift QPSK signal receiver even when the mean frequency differs from the carrier frequency due to the offset of data.
