Abstract: 820,072. Folding paper. JEYES' SANITARY COMPOUNDS CO. Ltd. Feb. 18, 1958 [May, 13, 1957], No. 15166/57. Class 100(1) Apparatus for producing single-folded paper sheets interfolded with one another comprises pairs of rollers for cutting two webs of paper into sheets, a pair of folding rollers for receiving the cut sheets, and a pair of oscillating fingers for completing the folding operation, the folding rollers having a diameter greater than that of the cutting rollers but being caused to rotate at the same angular speed whereby each sheet is folded about a line displaced from its centre line. Two webs of paper P and PP to be cut into sheets and interfolded so that the fold in each sheet does not occur in the centre of the sheet are drawn between cutting rollers C, CC and drive rollers D and DD where they are cut into sheets of the required length, the position of the cutters being such that the leading edge of a sheet cut from one web coincides with the middle of a sheet cut from the other web. The cut sheets are stripped from the rollers D, DD and guided to folding rollers E, EE by stripper bars SB the distance between the two sets of rollers being slightly less than the length of a sheet. Rollers E and EE have a diameter slightly larger than rollers D and DD but are driven at the same angular speed so that as soon as a sheet is gripped by the rollers E, EE it is accelerated and advanced with respect to the next succeeding sheet. Each roller E, EE is provided with a pair of tucking blades and a pair of grippers, 1, 2, 3, 4 and 5, 6, 7, 8 respectively which fold a sheet at the point corresponding to the leading edge of the next succeeding sheet. Since the folded sheet has been advanced with respect to that following the fold line is displaced rearwardly from the middle of the sheet and the sheets are interfolded eccentrically with one fold longer than the other. Cam-operated oscillating folding fingers F and FF co-operate with the rollers E and EE and serve to complete the folds and deliver the interfolded sheets to a receiver K. In modified apparatus, the blades and grippers on the folding cylinders are replaced by a line of pins on each roller, and the folding fingers are straight instead of being curved.

Abstract: 203,755. Humphreys & Glasgow, Ltd., (Taussig, J. H.). June 6, 1922. Alarms.-An automatic water gas plant is provided with an electric signal system of the kind wherein indicators such as lamps are controlled by switches in accordance with the valve movements, the said system being adapted to operate an audible alarm in the event of any one valve of the whole set or of a limited number thereof not being in its right rest or limit position. The valves A - - F operated by elements 1, 2 are each provided with two circuits both of which include a lamp, one circuit being closed to light the corresponding lamp by means of a switch 4, positioned on the particular valve rod, during the " run," the other being similarly closed during the " blow." The lamps are mounted as shown, the lower row indicating the rest position of the valves during the " blow " and the next upper row for indicating during the " run," while the lamps 70, 71 indicate whether the circuit is energized or not. The circuits referred to, in the case of the generator blast valve F, for example, comprises leads 21, 20, 22 23 and lamps 24, 25 which are connected in branches 26, 27 to two contacts of the switch 4 the arm of which is connected by a lead 28 to a wire 29. The position of the switch depends upon the rest position of the valve and the lamps 24, 25 indicate, according to which is lighted, the position of said valve. Both branches 26, 27 will remain open should the movement of the valve be incomplete. The alarm 5 is interposed in a local circuit 6 including a battery 7, hand switch 8 and two relays 9, 10 arranged when de-energized to close the circuit 6 and sound the alarm. The relays 9, 10 are connected in branches to switches, which may be parts of the switches 4, said switches being arranged in series with the relays.

Title: Fluorescence gas analyzer
IPC: G01N21/64
Filed: 1974-04-10
Abstract: 1440035 Fluorescence gas analyzers MASSACHUSETTS INSTITUTE OF TECHNOLOGY 10 April 1974 [12 April 1973] 16008/74 Heading G1A In an apparatus for measuring small amounts of a given gas in a flowing gas sample, the sample is caused to fluoresce by a suitable beam of radiation, and the fluorescence is measured by a detector positioned to minimize the amount of reflected or scattered radiation it receives. In Fig. 1 the gas sample is supplied to a chamber 3 via a pipe 4, and is illuminated by light from a source 1. The sample may be a vehicle exhaust for example, in which SO 2  or NO are to be measured, or may be a sample from the atmosphere; it is basically a carrier or background mixture containing a small amount of the gas to be analyzed, and it is found that the amount of fluorescence is linearly related to the amount of this gas for any given carrier mixture. The fluorescence is detected at 15 via a filter 37, chamber 3 being so baffled and shaped as to minimize the amount of non-fluorescence received. The light from source 1 is made mono-chromatic at 2, the wavelength of the mono-chromator and of filter 37 being chosen according to the gas to be analyzed. The source may be replaced with a laser, frequency doubled as necessary. A chopper may be placed at 18, and consists of a rotating disc half of which is transparent and the other half is an absorption cell containing the same gas as the particular gas to be measured in the sample. As the disc rotates it produces a cyclic modulation at sensor 15, and a switch 30, Fig. 5, synchronized with the chopper by means of a light sensor 27, switches the signal from sensor 15 between capacitors 28, 29. Meter 16 displays the difference of the stored signals, thus eliminating effects due to light scattering or sensor dark currents. Calibration:- as mentioned above, for any given carrier mixture the fluorescence is linearly related to the amount of the particular gas being measured; if the carrier gas is changed, the slope of the linear relationship is changed because the carrier gas determines the amount of quenching &c. that occurs in the fluorescent emission process. The apparatus must therefore be calibrated in use without altering the carrier gas significantly. This is done by adding a known amount of the particular gas being measured to the sample, this amount being small compared with the amount of the carrier, but being much greater than the amount of the particular gas in the sample. For example, the amount added may be 1% of the carrier flow, which is about one hundred times the expected amount of the particular gas. Thus the response of the sensor to the known amount added is found, and the apparatus is adjusted, e.g. by a variable resistor before the meter or by changing the voltage supply to a photo-multiplier acting as sensor 15, until its reading is the same as the known added amount. The known amount is added by means of a capillary tube and a flowmeter, Fig. 3 (not shown).
