Patent GB-333173-A (GB)
Abstract: 333,173. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). May 2. 1929. Phenanthridone and derivatives thereof are prepared by treatment of fluorenone or a derivative thereof with hydrazoic acid, advantageously in the presence, of a mineral acid, and an inert solvent. Nitrogen is evolved and the produce separated by pouring into water. The fluorenone oxide is probably formed initially, and undergoes the Beckmann change to give the corresponding phenanthridone. The compounds are intermediates for dyes and pharmaceutical products. In examples, hydrazoic acid, dissolved in benzene, acts on a concentrated sulphuric acid solution of (1) fluorenone, (2) 2 : 7-dibromofluorenone, (3) 2-nitrofluorenone, (4) 2-aminofluorenone, fluorenone-4- carboxylic acid, 2-hydroxyfluarenone, or 3- hydroxy-1: 2-benzofluorenone, to give the corresponding phenanthridones. 3-Hydroxy-1 : 2-benzofluorenone is obtained by benzoylating alpha-methoxynaphthalene in carbon disulphide, in presence of aluminium chloride, and causing ring closure and saponification by fusion with aluminium chloride.

Title: Improvements in light filters
IPC: G02B5/22
Filed: 1948-12-31
Abstract: 673,948. Colour filters. ROUY, A. L. M. A. Dec. 31, 1948, No. 33603/48. Class 97 (i). [Also in Group XL (b)] To enable a number of light filters of substantially equal light transmittance characteristics to be formed from a number of partial filters formed by the usual manufacturing processes and therefore diffusing slightly in characteristics, the partial filters are tested and, if necessary adjusted e.g. by grinding to have substantially the same total transmittance, and the transmittance of each is then measured in combination with a cut-off filter which only passes light above or below a certain wavelength within the range of wavelengths passed by the partial filters. The value so obtained, called the " cut-off " value " is subtracted from a standard value, the result being accorded the same appropriate algebraic sign, and the partial filters are then formed together in. pairs to form the joint filters, the members of each pair being chosen to have cut-off values of equal numerical value but opposite sign. The testing may be carried out by a photocell 3 connected to a microammeter 4, the light 1 being passed first through the partial filter 2 alone to test the total transmittance, and then through the filter 2 and cut-off plate 5 to give the cut-off values. Fig. 2 illustrates the principle of the cut-off plate which may have a transmission curve EFGH while the partial filters are assumed to have transmission curves ABCD, A<SP>1</SP>B<SP>1</SP>C<SP>1</SP>D<SP>1</SP> of the same shape but, owing to manufacturing differences, displaced along the wavelength axis. The difference in size between areas EFCD and EFC<SP>1</SP>D<SP>1</SP>, which are proportional to the cut-off values gives a measure of the relative displacement of the curves and by choosing filters as indicated above, the combination will give substantially a predetermined transmittance curve. The two partial filters may be formed by cementing or by attaching tape to their edges.
Patent GB-1240325-A (GB)
Title: Electronic taximeter
Inventor: BRUCE-SANDERS JAMES FREDERICK
IPC: G04F10/04
Filed: 1968-07-15
Abstract: 1,240,325. Electronic taximeters. J. F. BRUCE-SANDERS. 15 July, 1968 [14 July, 1967; 20 Dec., 1967], No. 33699/68. Heading G4T. An electronic taximeter includes two constant polarity pulse generators emitting time and distance pulses respectively, a counter, control means actuated by the distance pulse train to prevent the application of the time pulse train to the counter when the distance pulse frequency exceeds a certain value (which may be zero), and a read-out for displaying the appropriate fare as determined by the counter. As shown, the outputs from distance and time pulse generators 10 and 11 pass through frequency dividers 12 and 13, whose ratios are chosen so that each pulse issuing from either 12 or 13 represents the same amount of fare. When the meter main switch (not shown) is moved to its " normal hire " position, a logical " 1 " signal is applied to input 20 of a NAND gate G2. The other gate input is fed from the distance pulse generator 10 and the gate output is fed through an inverting gate G3 to a reset terminal 19 of divider 13, so that the divider is continually reset and issues no time pulses when distance pulses are being produced. The meter main switch may be moved to a " distance only " position in which divider 13 gives no output whether the taxi is moving or not. The output pulses from G4 and/or G5 are totalled by a slave counter 15, which displays each trip fare on read out 17 and is reset after each fare, and by a master counter 16, which sums successive fares over a period and may be connected to read-out 17, but may only be reset by use of a key. In order to correct the distance pulse rate, which will be too high when the taxi's tyres wear, a unit 24 may be connected to a selected terminal 27 of divider 12 to subtract a preset number of pulses from the count. The initial " flag-fall " charge for each hire period may be entered into counters 15, 16 by a circuit, Fig. 3 (not shown), triggered by the main meter switch. A circuit, Fig. 4 or Figs. 6 and 7 (not shown), may be provided for entering charges made for calling the taxi, via a base station, by radio. A circuit for Fig. 8 (not shown), feeding the outputs from the distance and time pulse generators, the " flag-fall " charge circuit and the radio call charge circuit to the meter counters and read out, includes means ensuring that the first n distance or time pulses are not counted when a " minimum fare " (which includes the charge for these n pulses) applies.

Filed: 1945-12-14
Abstract: 614,330. Photo-electric exposure meters. GOSLING, A. G. Dec. 14, 1945, No. 33897. [Class 40 (iii)] [Also in Group XX] An exposure meter of the kind comprising a selenium cell, a moving coil meter, and three concentric scales marked in exposure times, lens apertures and emulsion speeds respectively, the first two scales being relatively movable to bring different calibrations thereon into coin cidence and inversely calibrated so that equal distances on the two scales represent equal changes in the light admitted during exposure, and the third scale being movable with one of the first two scales to bring any emulsion speed into coincidence with the instrument pointer, is characterised by the features that the meter is contained in a generally square casing and that the scales have an arcuate length of a quadrant or less, are contained within the square form of the casing, and are arcuate about a centre near one corner of the casing. In the form shown, a selenium cell, a moving coil microammeter and a scale marked in shutter speeds are mounted on a base-plate over which fits a cover 3 enclosing the instrument and bearing an arcuate slot 8 through which the shutter speed scale 5 and the pointer 9 of the microammeter can be observed. The pivot of the pointer and the centre of curvature 23 of the scale 5 are diagonally opposite. A sector-plate 1 pivoted at 23 on the cover 3 bears a scale marked in lens apertures and also a Scheiner scale of emulsion speeds, the graduations of the two scales being linked. The scales are logarithmic and so arranged that when, for any meter indication, the lens aperture mark linked with the emulsion speed mark for the emulsion in use is brought into coincidence with the exposure time indicated on scale 5 by the pointer 9, coincident markings on the sector 1 and the scale 5 give a series of equivalent combinations of the lens aperture and exposure time appropriate to the speed of the emulsion and the light intensity indicated by the meter. The selenium cell 10 is supported by flanges 11A, 11B and connected through contact strips 12, 14, plate 13 and hair-springs 18, 19 to the moving coil 17 of the meter. Specification 458,645, [Group XX], is referred to.
