Title: Improvements in or relating to infra-red gas analysers
Inventor: MARTIN ALBERT EDWARD
IPC: G01N21/37
Filed: 1955-04-06
Abstract: 791,737. Infra-red gas analysers. PARSONS & CO., Ltd., C. A. March 26, 1956 [April 6, 1955; Oct. 6, 1955], Nos. 10111/55 and 28475/55. Class 40 (3). An apparatus for the infra-red analysis of two components gas 1, gas 2 of a mixture includes rotating shutter S interrupting both radiation beams simultaneously, tubes A and B, filters D and E filled with gas 2 and gas 1 respectively, and a detecting capacitor C operating in a known manner and having its two chambers filled with a mixture of gases 1 and 2 or any single gas or gas mixture with regions of absorption common to one or more of the absorption bands of gases 1 and 2. To analyse for gas 1 the sample is passed into tube A and dry air free of carbon dioxide through tube B; and vice versa for gas 2. Balancing shutter F may be introduced (or the heating current supplied to one of the radiation sources may be varied) and so adjusted that the indicating meter, fed from a non- synchronous rectifier associated with the apparatus, has the portion zero to mid-scale available for readings corresponding to gas 2 analysis and mid-scale to full-scale corresponding to gas 1 analysis; alternatively, to obtain the use of the full meter scale for each gas the meter zero can be made to correspond to both tubes A, B containing non-absorbing gas and the error arising from the indeterminateness of the minimum point overcome by introducing a small obstruction into each radiation path. Indicating means with the meter fed from a rectifier whose contacts are driven synchronously with the radiation chopper S are outlined. In a modified arrangement, two separate detecting chambers are used, filled with gas 1 and gas 2 respectively, the capacitors of each chamber being so arranged that the energy absorption in one chamber increases capacitance and in the other, decreases capacitance ; the capacitors may be connected in parallel, or in series.

Patent GB-168300-A (GB)
Title: A device for automatically making and breaking an electric circuit with the commencement and ceasing of speaking currents and similar electric oscillations
IPC: H01H51/30
Filed: 1921-04-06
Abstract: 168,300. Telegraphon Ges. Aug. 24, 1920, [Convention date]. Electromagnetic interrupters; contacts; alternating-current relays.-Relates to inertia switches or contacts of the typeemployed for automatically recording telephone messages or other speech. One element of the contact consists of a pivotally-mounted hammer-headed arm M which normally rests against the other contact-part J. The latter is carried on a pivoted armature E ending in a resilient tongue G resting on an adjustable abutment H. Accidental variations in the basic line current cause merely a greater or less flexing of the armature E, G, and this movement is followed by the arm M without breaking contact. When speech currents are superposed, however, the inertia of the hammer contact M is too great to follow the rapid vibrations set up in the armature, and the relay circuit formed by the two points is broken, thereby bringing the record-driving motor into operation. Fig. 2 shows the circuit arrangements of a system for recording telephone messages or the like. Voice currents in the lines 1, 2 are amplified by a valve 6 and, after actuating the recording-needle 8, pass through the winding 10 of a microphone booster 11, 12, to the winding D shown also in Fig. 1. The special contact M controls the current in a polarized relay 15, so that when this circuit is broken by speech currents, the contacts of a time relay 16 are closed. The driving-motor 14 of the recording-cylinder 9 is thereby started and continues so long as speech lasts. In order to adjust the sensitivity of the contact M, the relay is rotatably mounted on a pivot N so that it can be inclined more or less to the horizontal.

ACMU is the available milk clotting units of activity still retained by an enzyme and is a convenient measure of activity. Additionally the enzyme solution may be subsequently with a suitable disulphide inactivator. Example III illustrates the synergistic effect obtained using a two stage pH treatment.

Abstract: 104,111. Winn, P., and Wilkes, A. H. July 21, 1916. Check or non-return valves; valves closing with rush of fluid.-A valve device, particularly applicable for use in the gas-supply pipe of burners supplied with air under pressure, is provided with a means to ensure that the valve shall close promptly in the event of a back-rush of fluid. In the form shown, the valve member a has a guide-spindle b working through a spider c and is provided with a flared flange k surrounding the valve seat e. The valve is normally in the position shown, the fluid passing to the outlet ga through ports j. The flared flange k is arranged opposite a conical part g surrounding the outlet ga, so that in the event of a return flow, the fluid is directed on to the back of the valve member to close the valve. A floating disk may be arranged within the flared flange. A hinged or flap valve may be substituted for the lift valve, and the whole apparatus may be inverted, so that gravity tends to seat the valve.

Apparatus for determining the frequency of a periodic phenomenon of very low frequency comprises means responsive to the phenomenon for allowing electrical signals of a known repetition rate to pass to a counter for a period equal to one cycle of the phenomenon, and electrical means for dividing the number registered by the counter at the end of the period into unity. A shaper circuit 7 develops a pulse of duration equal to one cycle of the signal entered at terminal 6 and opens a gate 8 for this period to allow clock pulses from a source 9 to pass to a counter 10. The required frequency is given by the reciprocal of this number which is obtained by dividing it into unity. The dividing means which, preferably. comprises multicathode counting tubes, is described in Specification 770,034, [Group XIX]. Transfer of the number to the dividing means 1 ... 5 may be performed by uniselector switches or coincidence circuits.
