Title: Gas monitoring apparatus
Inventor: EINSTEIN HARRY
IPC: G01N21/53
Filed: 1968-11-01
Abstract: 1,241,225. Photo-electric detection of particles in gases. H. EINSTEIN. Nov.1, 1968 Nov. 8, 1967], No.51841/68. Heading G1A. [Also in Division G2] Solid particles carried in gases, e.g. flue gases, are detected by passing a sample of the gas through a testing tube and measuring the amount of light transmitted or back-scattered by the particles in the gas. In the arrangement of Fig. 1, a sample of gases from flue 12 is led through a valve box 22 into the testing tube 48 and back to the flue through tube 52. The flow of gases is aided by compressed air-flow through tube 74. To measure absorption of light by black particles in the gas, light from a lamp 63 is reflected by a partial reflector down the length of tube 48 and is reflected back by retroreflector 58 which is adjacent opening 54 at the lower end of the tube 48. The light returns undergoing further absorption, to a detector 65 where output is indicated by meter 72. If scattered light from white or light-coloured particles is to be measured, a non-reflective cover 56 is moved over reflector 58. An air jet 66 is used to prevent the build-up of sediment on sight glass 64 hinged on opening 62 in the tube. In carrying out measurements, the valve box 22 is used, by adjustment of flap 30 to cover tube 20, to open 28 and allow ambient air to be drawn through, allowing zeroing of the meter. Then the flap 30 is moved to the position shown, for sampling. The flap may be moved to uncover both openings allowing flushing of tube 20 with ambient air. Floor 40 of the valve box is removable for cleaning. Modifications. In Fig. 3 (not shown), at the top end of tube 48, the compressed air inlet 74 is replaced by one axial with the outlet 52 and sight glass 64 is unnecessary. A rotatable, Fig. 4 (not shown), or translatory, Fig. 5 (not shown), filter carrier may be used to put different density filters or an UV filter into the light path. An auxiliary light source (82) may be present for use in scattering tests. The source may be at the bottom end of tube 48, replacing retro-reflector 58.

Abstract: 1336725 Automatic focusing CANON KK 5 Nov 1970 [15 Nov 1969] 52790/70 Heading H4D In an automatic camera focusing system, a modulated infra-red light beam from a source not shown is projected on to the object to be focused and the reflected light (a circular patch in the embodiments) is directed by lens system 3, 10 on to a beam splitting wedge 11 1 , 11 2 , from whence the two images are directed on to respective photo-detectors 14 1 , 14 2 . It is seen that, with respect to the infocus position (Fig. 2B) of the two images on their photo-detectors, the images separate for one sense of out of focus and converge for the other sense of out of focus. The separation and convergence is detected by providing off-centre masks 13 1 , 132 in front of the photo-detectors, such that the images portions passing through to the detectors are only equal in the case of focus. The resulting out of focus differences between the detector outputs is used to actuate a servo focusing system (Fig. 1, not shown). The masks 13 1 , 13 2  may have wedge shaped apertures, Fig. 4, with cylindrical lenses 12, 12 2  to stretch the images. The masks may be formed on the surface of a planar photo-detector and comprise the electrodes of the detector, Fig. 5 (not shown).

The welding may be gas shielded, preferably by CO 2 , alone or mixed with other gases, or by inert or inert and active gas, flux-submerged, effected by coated electrodes, or unprotected. The constant D.C. is provided by a source 9 connected to the electrode and a workpiece 10. The D.C. pulses are provided by a D.C. current stabilized charging device 1 (e.g. comprising a current rectifier) in circuit with a capacitor 2 in series connection with a choke 3, a primary winding of a transformer 4, and a thyristor 5. The transformer secondary winding is connected to the electrode and the workpiece, and a diode 7 blocks current from the source 9. A further thyristor 6 shunts the transformer primary winding, and the two thyristors are controlled by a controller 8 which together with the device 1 is controlled by the source 9. In operation, on striking of an arc from the source 9, the device 1 is switched on and charges the capacitor 2, and the controller 8 generates signals of pre-set frequency to trigger the thyristor 5 and discharge the capacitor. The capacitor, choke, primary winding and thyristor 5 provide a resonant circuit such that after each capacitor discharge the capacitor is partially charged with opposite polarity to render the thyristor 5 non-conductive, until, after a predetermined time, the device 1 again charges the capacitor to the initial polarity for the cycle to be repeated. The capacitor discharges produce D.C. pulses in the transformer secondary winding which are fed to the electrode through the diode 7. On interruption of the arc a further signal from the source 9 causes the controller 8 to trigger and then block both thyristors 5, 6 simultaneously, and the device 1 to discontinue charging the capacitor.
