Title: Light scattering photometer recording unit
IPC: G01N21/25
Filed: 1972-05-01
Abstract: 1394274 Measuring light scattering photoelectrically SCIENCE SPECTRUM Inc 1 May 1972 [3 May 1971] 20216/72 Heading G1A The light scattering properties of a plurality of individual samples, e.g. bacteria/drug solutions in cuvettes 116, are examined by bringing each sample in turn to a testing station, irradiating it with light, e.g. from a laser 34, and measuring the intensity of scattered light as a function of wavelength. The angular scan is achieved by a mirror arrangement 40 which travels along a track 42 as soon as a cuvette is stationary and thereby directs light to a photo-multiplier, photo-diode or bolometer in housing 64. Instead of a continuous intensity measurement, a number of measurements may be made at different positions in the angular range available. The output from the photo-cell is displayed on a chart recorder. One of the samples may be a reference e.g. a solution of a particular bacteria only, and the others are then samples of the same bacteria to which different drugs have been added. In this case the reference output is compared with each of the other outputs in a logarithmic ratio device, whose output is applied to the chart recorder or punched on to a card. The sequence of events including the stepping of cuvettes into position and the recording of the measurements is governed by control circuitry, Fig.6 (not shown).

Title: Improvements in or relating to the regulation of currents having high or musical frequencies superimposed on distribution networks
IPC: H04B3/54
Filed: 1934-07-10
Abstract: 434,559. Signalling over power circuits. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ETMATERIEL D'USINES A GAZ, 12, Place des Etats-Unis, Montrouge, Seine, France. July 10, 1934, No. 20265. Convention date, July 11, 1933. [Class 40 (i)] In a system for signalling over power distribution networks by high or musical frequencies superposed thereon, an estimate of the voltage (across B, C) available at the receivers connected to the feeders 3 .. 6 is made by measuring the difference between the voltage put in to the superposing transformers (7 .. 10) and the voltage at a point (transformer 21) in the network on the near side of the superposing transformers. This differential voltage is then used automatically to adjust the input voltage to a desired value, or the adjustment may be made manually. The invention may be applied to continuous or multi-phase current networks, but as shown is applied to a single phase network comprising mains 1, 2 and feeders 3 to 6. The signalling source 17 is connected automatically or manually by a switch 16 to the superposing transformers 7 .. 10. The differential voltage due to transformers 21, 22 is fed over a circuit 26 ..28, rejecting the power frequency but resonant to the signalling frequency, to a rectifier which supplies a galvanometer 31. The galvanometer needle 32 is adapted to close contacts 34, 35, according to whether the voltage is excessive or insufficient, to drive a motor 37 in one or other direction for the purpose of adjusting the output of generator 17. Several signalling frequencies may be used, the circuit 26-28 being tuned according to the frequency in actual use. The signals may be modulated or intermittent, in which case the measurement and adjustment is effected by a preliminary unmodulated transmission to which the receivers do not respond.

Void [Published under Sect. 91 of the Acts]. Class 98 (ii).] For a multi-layer film or a tripack, emulsions are used in which a proportion of silver has been reduced by the dilution of a normal emulsion with gelatin to such an extent that the resulting emulsion is unsuitable for normal purposes. The sensitivity of the emulsion is increased before dilution by ripening or other means to such an extent that in its undiluted form would give the emulsion cloudy images, but after dilution a film of sufficient sensitivity and gradation is obtained with no greater degree of cloudiness than is shown by normal emulsions. Developers with a high alkali content are used, e.g. metol and caustic soda. The films of a film pack in which one or more of the films are exposed through the base are developed separately.

Title: An improved current supply for electric lamps
IPC: H05B37/02
Filed: 1943-12-13
Abstract: 581,373. Supply systems for incandescent lamps. LYNCH, A. C. Dec. 13, 1943, No. 20894. [Classes 38 (ii) and 38 (iv)] To avoid cyclic variations of light output from an incandescent lamp operated from a sinusoidal current supply, a device for converting the supply waveform into one of approximately rectangular form is interposed between the lamp and the supply so that current supplied to the lamp is substantially constant in strength over a complete cycle. Fig. 2 shows a particularly suitable waveform, which is obtained by combining a fundamental sinusoidal current with its third harmonic in suitable phase relationship. Such a waveform may be obtained by transformers, as shown in Fig. 3, wherein the exciter lamp EL of a sound-reproducing system, comprising lenses L, LS, sound track ST and photo-electric cell PC, is supplied from the series connected secondary windings of transformers T and SCT, the primary windings of which are both supplied from the sinusoidal source. The core of transformer SCT is saturated whilst that of transformer T is unsaturated. The phase of the secondary current is controlled by a condenser C. In alternative systems thermionic valves are used to convert the waveform of the supply, thus a lowpowered valve may generate from a sinusoidal supply a square wave voltage which is superposed in opposite phase on a sinusoidal voltage derived from the supply, the resultant wave, after power amplification, being superposed on a sinusoidal wave of greater amplitude to produce a resultant wave which is substantially square or " double humped."
