Patent GB-2476237-A (GB)
Title: Calibration of electrochemical sensor
Inventor: LAWRENCE NATHAN
IPC: G01N27/416
Filed: 2009-12-15
Abstract: The method utilises a sensor comprising electrodes and a mediator compound capable of undergoing a cycle of oxidation and reduction in response to varying potential applied to the electrodes, where the mediator also undergoes a portion of the cycle through chemical reaction with the analyte. The sensor and sample fluid are brought into contact sufficiently for the analyte to react with the mediator, and in a voltammetry procedure, potential is applied to the electrodes while observing current flow during reaction between the mediator and the analyte, to observe analyte concentration. Calibrating the sensor includes applying a rapidly changing potential to the electrodes and observing current flow, the change of potential and observation of current being sufficiently fast to allow and observe electrochemical oxidation/reduction of the mediator taking place independently of analyte concentration, thereby observing the mediator concentration. The rapid change of potential is provided by pulse or square wave voltammetry.

Filed: 1972-03-03
Abstract: 1352471 Measuring electric fields BURLINGTON INDUSTRIES Inc 3 March 1972 [11 March 1971] 10063/72 Heading G1U An electric field measuring device comprises a conductive wire mesh probe 1, Fig.1, a source of alpa particles 2 which creates an ionized cloud 4 around the probe, an insulating plate 5 which extends beyond the ionized cloud 4, and an amplifier 6 and voltmeter 7 which measure the potential of the probe 1. In operation the probe 1 is inserted into the field to be measured, for example the atmosphere in a spinning or weaving mill, the ionised cloud 4 preventing either the source 2 or the probe becoming charged by induction - since any charge that may be induced is immediately neutralised by an ion of appropriate polarity from the cloud - and the potential of the probe, which now acts as a constant potential source having the potential of the field to be measured, is measured. The device may be used in association with an air conditioning plant so that when a field above a certain magnitude is detected, ions of the appropriate polarity are added to the air being circulated so that the magnitude of the field is reduced.

Title: Improvements in or relating to an apparatus for spectrochemical analysis by means ofx-rays
Inventor: SCHUMACHER WILHELM WALTER BERT
IPC: H01J33/00
Filed: 1959-03-24
Abstract: 861,409. Apparatus for X-ray spectrometry. ONTARIO RESEARCH FOUNDATION. March 24, 1959, No. 10150/59. Class 98(1) An apparatus for X-ray spectrometry has a vacuum chamber in which an electron beam is produced, a first pressure stage stretch through which said beam passes to the outside atmosphere where it strikes a specimen to produce X-rays, and a second pressure stage stretch providing a passage for the X-rays into a vacuum chamber in which is located an X-ray spectrometer, the axes of the electron beam and of the spectrometer being inclined to each other. A pressure stage stretch consists of a series of apertured chambers maintained at increasing degrees of vacuum, so that a clear passage is provided from a high-vacuum region to the atmosphere. In Fig. 1, the two continuously evacuated chambers Z 2 , Z 1  act as pressure stage stretches between the electron gun chamber R E  and X-ray spectrometer chamber R sp  respectively, and the atmosphere outside the structure M. The electron beam (axis X 1 ) passes through apertures f, d, and finally a, impinging on the target or specimen 1 (which may be solid or liquid) over an area D E  centred at 0. The X- rays produced re-enter the apparatus through apertures b, e, and g (axis X 2 ) to be analyzed by the spectrometer R sP . The apertures are chosen so that the cone of radiation R derives from an area D R  on the target which is substantially smaller than the area D E  bombarded by the electrons. The apparatus is so arranged that the axes X 1  and X 2  intersect on the target, and in the modification of Fig. 2 the spectrometer chamber is connected to the main structure M by flexible walls so as to allow of adjustment of axis X 2 , and consequently of the intersection point. The area of the target under bombardment is continuously observed by a microscope 9, either directly or by reflection. If the microscope is focused at the intersection of axes X 1  and X 2 , the correct position for a target 1 can be determined by moving it until it is in focus. Between the exit and entrance apertures a, b, and the specimen, a flat chamber may be provided (Fig. 3, not shown), which can be flooded with an inert gas in cases where the presence of air would interfere with the analysis.

Title: Improvements in or relating to arrangements for the safeguarding of railway level crossings
IPC: B61L29/28
Filed: 1934-04-05
Abstract: 441,114. Railway level-crossing signals. NAAMLOOZE VENNOOTSCHAP MACHINERIEEN-EN APPARATEN FABRIEKEN, 30, Croeselaan, Utrecht, Holland. April 5, 1934, No. 10343. Void [Abridged as open to inspection under Sect. 91 of the Acts, Oct. 15, 1934]. [Class 105] Two short insulated rail lengths A, B and C, D, with associated relays 1, 2, 3, 4, are provided at each end of a stretch of track containing a level crossing whereby an approaching train initiates a warning signal which is cancelled when the train passes the further one of two short insulated rail lengths G, H situated one on each side of and adjacent the crossing ; the rail length E at the crossing itself is not insulated. The signal may also be initiated on the approach of a branch line train, the branch line having two short insulated rail lengths connected to the short insulated rail lengths of the main line. A train approaching the crossing from the left on reaching rail length A shunts the relay 1 a back contact 12 of which, in conjunction with a back contact 22 of the relay 2, then shunts the relay 5 of the near section 9 adjacent the crossing ; a back contact 51 of the relay 5 lights the warning signal R. The train next reaches rail length B energizing the relay 2 which sticks up (when the rail lengths A, B are left) over front contact 11 of relay 1, its own front contact 21, and front contact 64 of the relay 6 for the rail length H adjacent but beyond the crossing. The relay 5 continues to be shunted, but now over its own back contact 52 and front contact 22 of the stuck up relay 2 so that the warning signal R continues until the train passes the rail length H immediately beyond the crossing and directly shunts the relay 6 to break the stick circuit for relay 2 which in turn opens its front contact 22 to break the shunt across relay 5. The previous circuit to the warning signal is thus opened at contact 51 of relay 5, but the warning signal continues to be given over back contact 61 of relay 6 until the train has left the rail length H whereupon the clear signal is lit. When the now receding train reaches rail length D the relay 4 is energized and so closes contact 43 to connect up rail lengths D and C (relay 6 not at this time having been shunted to open contact 63) and thus the train deenergizes relay 3. The relay 6 is not shunted since back contact 42 of relay 4 had opened before back contact 32 of relay 3 closed. If a train should enter the stretch, say at the left hand and then back out, the stick circuit of relay 2 would be broken when the train backed on to the rail length A and when the train further backed off this rail length A the remaining shunt circuit for relay 5 would be opened and thus the apparatus would again be normal.

Title: Improvements in and relating to warp-stop mctions for looms
IPC: D03D51/20
Filed: 1930-04-01
Abstract: 352,395. Warp stop motions for looms. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Maschinenfabrik R³ti vorm. C. Honeggar ; R³ti, Zurich, Switzerland.) April 1, 1930, No. 10372. [Class 142 (i).] The fall of a heald due to warp breakage stops the relative displacement of oppositely toothed bars 3, 6, and causes the loom to be stopped before the beat-up and with the lay at a distance from its foremost point. The relative displacement of the bars 3, 6 is produced by mechanism that is independent of the heald movements, so that the stop motion may be used in looms wherein groups of heald staves remain in the lower shed for several picks. Each bar 6 may be reciprocated in a fixed oval guiding bar 3 on a heald frame 1 by a bell crank 10 controlled by a spring 10<1> and pull rod 12 having a positioning ring 31 operated by a lever 30 controlled by a rod 32 furnished with a spring and actuated by a lever 34 controlled by a cam 35 and spring 33. Normally the parts assume the successive positions shown in Figs. 1 and 2, and as shown in Fig. 1, a pull rod 51 attached to the lever 30 moves a locking lever 52 out of the path of a lever 36 carrying a vertical rod 39 and actuated by a cam 38 and spring 37. Consequently at the beat-up the lever 36 is raised by the spring 37 and a double-armed repeller 41 pivoted on the rod 3!) is raised out of the path of a thrust piece 44 on the lay. When the free movement of the bar 6 is stopped by a fallen heald, the ring 31 holds the lever 30 in the position shown in Fig. 6, the rod 51 moves the lever 52 into position to lock the lever 36, and the rod 39 holds the repeller 41 in the path of the part 44 whereby it is operated at the beat-up. An arm 40 through which the rod 39 passes is thus operated and stops the loom by known means described. The parts 41, 44 contact when the lay is at some distance from its forward position and to allow for the forward movement of the lay whilst the loom is stopping, a stationary roller is arranged to act on and rotate the repeller out of the path of the part 44. The rod 39 may be depressed by hand to put the stop motion out of action and be held depressed by a spring pawl. In a modification described, two oppositelytoothed bars are lowered into an untoothed bar on the heald frame when this is raised, but are raised therein and reciprocated in opposite directions to feel for a fallen heald when the heald frame is lowered. Other modifications are described wherein each heald frame has two or three rows of healds.
