[Also in Divisions B1-2] Apparatus for simultaneous photometric analysis of a plurality of samples carried in a transverse row of depressions in each of carriers 27 on conveyer 31 comprises a row of photoelectric cells 58, one for each depression, light source 59 preferably having a very narrow slit 60 to allow measurement during movement of the conveyer (see 1, 119, 984), and display and/or recording means for the results, for example two parallel rows of lamps 65, 66, either or both of which is illuminated depending on the range of values within which the result lies. Two sets of photometric measurements may be made, one set at the start of the reactions in the depressions in carrier 27 and one set as shown, the outputs of each pair of corresponding photo-electric cells being connected via leads 62 and 63 to a memory and discriminator block 64 in which the difference in the two values is determined. After the photometric measurement each sample carrier 27 together with its associated sample label (24B) travelling on a neighbouring conveyer is photographed. Light box 67 is used to project an image of the carrier on to translucent plate 69 which also overlies lamps 65, 66. Photo-sensitive paper or film 73 from roll 74 engages plate 69 and receives an image of the rows of lamps 65, 66, one sample carrier 27 and the sample lable. The paper or film 74 passes through developing and fixing baths 75, 76, engages a second photosensitive paper or film 77 from roll 78 and passes over light box 79, then is reeled at 75 while the second paper or film 77 is developed and fixed in baths 80 and 81 and cut into lengths by cutter 82.

Title: Ignition system
IPC: F02P15/10
Filed: 1973-08-20
Abstract: 1450451 Ignition systems; timing ignition KYBERNA GmbH 20 Aug 1973 [21 Aug 1972 6 March 1973] 39278/73 Heading F1B [Also in Division H1] An ignition system for an internal combustion engine comprises terminals for connection to the primary 37 of an ignition transformer 38, means for applying a varying current to the terminals for a certain period for each ignition and two monostable circuits 44, 45 whose durations of unstable condition are variable according to respective operational and/or environmental conditions, the durations determining the starting and the finishing times respectively of the period. The D.C. voltage converter or transformer 20 has the object of converting the voltage of the D.C. voltage source 3 to a D.C. voltage of for instance 50 to 100V. The output 22 of the D.C. voltage converter 20 is connected to the input 23 of a known current regulator 24. The output terminal 35 of a voltage regulator 32 is connected with an input terminal 36 of the primary winding 37 of the ignition transformer 38. The terminal 39 of the primary winding 37 of the ignition transformer 38 is connected via the terminals 40, 41 of a switching stage 42 to the negative reference point 34 of the current regulator 24. The potentiometer 63 permits variation of the frequency of a pulse generator 43. The timing members 44, 45 are monostable multi-vibrators of known type. These monostable multi-vibrators are integrated circuits. The period of time for which the high voltage alternating potential is applied to the terminals 113 and 114 is determined by the timing member 44. Commencement of the generation of the high voltage alternating potential is effected via the moment of ignition transmitter 46 in conjunction with the timing member 45. As shown there is a breaker switch 86 which is actuated by a cam 87 driven by the engine. Numerous modifications are described. In one the D.C. voltage converter or transformer and the voltage and current regulators are omitted. As shown in Fig. 10 the ignition transformer has four primary windings 155 to 158 each associated with a pair of transistors. Fig. 16 (not shown) relates to modifications of the pulse generator 43 and timing member 44. In a further modification (not shown) a timing member 44  and a pulse generator 43 are associated with photosensitive devices. In another modification, Fig. 23, a modified D.C. voltage transformer 349 is employed and coupling circuits 338 and 339 are included. Figs. 25 to 27 (not shown) give details of the circuits 338 and 339 and the D.C. voltage transformer 349.

Abstract: 969,941. Surgical optical instruments. T. B. CLERK. (American Optical Co.). Oct. 17, 1962, No. 39353/62. Heading ASR. [Also in Division G2] A device for examining specimens, in particular of blood, comprising an elongated relatively thin fibre optical probe 10 (see Fig. 1), having a cross-section of such a size that the probe could be inserted into a blood vessel 28, the fibres being optically insulated from each other, and at one end of the probe the fibres are separated into two groups 20, 21 so that light can be passed down one of the groups 21 into the blood vessel and can be passed back up the other group 20, the other end of the probe having a thin-walled casing 11. In the embodiment shown, the casing is a hypardermic needle but in other embodiments it is a rubber tube and in Fig. 9 it is a plastic casing. The two groups of fibres when joined together may be placed side-by-side or coaxially relative to each other, the two being separated by insulating material, along at least part of their length. In the embodiment shown in Fig. 9 the light passes down tube 46, is reflected at mirror surface 49, 50, passes through a specimen of blood 51 flowing through a gap in the fibres and up through tube 47. In the colorimeter shown in Fig. 1, light from a source 12 is passed through filter 15 or filter 16, mounted on a slidable base 31, according to the required wavelength band, passes into the blood 29 as described above and is transmitted back to a photo-electric device 18 which measures the intensity of light falling on it. The blood comprises oxyhemoglobin and reduced hemoglobin which two components transmit different proportions of light at different wavelengths. Therefore by obtaining a reading from instrument 18 when the wavelength of light is such that both the blood component transmits it equally and another reading from the instrument 18 when the wavelength of light is such that the two components transmit by previously determined unequal amounts and comparing the two readings the oxygen saturation of the blood can be determined. In another embodiment the photoelectric device may be replaced by a magnifying piece. Specification 576,205 is referred to.
