Title: Method for measuring the concentration of gaseous oxygen or carbon dioxide in gaseous or liquid samples in particular in breath and blood samples
IPC: G01N21/77
Filed: 1977-04-12
Abstract: To measure the proportions of gases, a reagent solution is used which is specific for the gas whose proportion is to be measured and which discolours in a characteristic manner if the gas in question is present. The sample and the respective reagent solution are fed in and mixed together while maintaining a constant ratio of the amounts fed in or the mixing ratio of the sample and the reagent solution. The concentration of the substance producing the colour (O2, CO or CO2) is determined by measuring the absorbance in a photometer. Such a method makes it possible to carry out the measurement for three different gases in the same way and requires inexpensive chemicals only to be replaced in the process.

Title: Improvements in or relating to electrical signalling systems
IPC: H04M11/04
Filed: 1928-05-22
Abstract: 317,547. Automatic Telephone Manufacturing Co., Ltd., and Burns, G. A. May 22, 1928. Fire and like alarm systems.- In an electric signalling system of the type in which a plurality of branch stations are arranged in series in a loop and in which signals are transmitted by interrupting the loop, an additional register which is not operated on normal calls is provided which operates if the branch station is short-circuited or if the loop is broken. In the event of an earth fault developing in the loop a relay is provided to operate an alarm. The Figures show branch stations a - - e, each of which is normally short-circuited by springs 11, 12, the normal current in the loop holding a register P and a telephone relay TR operated. The call box includes a telephone calling relay T, a signalling key SK, a sounder S, and coils CD for preventing operation while another station is signalling. The operation of the box releases code wheel CW and closes the earth contact 20 so that register P, relay TR, and gong G are operated. The release of relay TR actuates relay ATR which locks and disconnects earth from battery B to prevent the short-circuit recording relay SC from operating and operates the lamp TL, pilot relay PR, and alarm AB. The alarm is stopped by operation of the telephone key TK which de-energizes relays ATR, PR. A break in the loop operates the alarm and gives a single record on the register and the attendant operates earthing key EK and the auxiliary register key APK. Calls from the conductor 13 then operate the auxiliary register AR and the gong G over an earth return while calls for conductor 10 operate relay TR and register P. The operation of relay TR operates the alarm and telephone lamp since key 16 forms part of the earthing key EK and is operated. In the event of the calling station being short-circuited the earth contact 20 closes a circuit through register P, battery B, and short-circuit recording relay SC, which being impulsed actuates the auxiliary 'register AR and the indicating lamp IL and the relay PR and alarm AB. Resistances X, Y are provided to make the effect of an earth connection substantially independent of the position on the loop and to limit the current on the occurrence of an earth fault. The key K1 brings a voltmeter V into circuit through key VT and allows an approximation to the position and magnitude of an earth to be obtained. Testing and telephone arrangement. The opening of the call box door opens springs 12 only and the depression of the telephone key T operates relay TR and the alarm but not the gong or register. The operation at the central station of the key TK restores relay ATR and actuates the telephone lamp TL. The central station calls the tester by including resistance Z in the loop circuit to operate the sounders S of any boxes that may be open.
