Title: Improvements in method of and apparatus for determining the intensity of colors
IPC: G01J3/28
Filed: 1929-12-28
Abstract: 349,565. Colour analysers. RAZEK, J., 270, Kent Road, Upper Darby, and MULDER, P. J., 347, Fairfax Road, Drexel Hill, both in Pennsylvania, U.S.A. Dec. 28, 1929, No. 39687. [Class 97 (i).] In a method of determining the spectral distribution curve of light from a body successive parts of the spectrum of light from the body are directed on to a light sensitive device e.g. a photoelectric cell, the resulting series of direct currents being measured by a galvanometer in a compensated audion amplifying circuit. Alternatively the body may be illuminated successively by light of selected wavelengths the reflected portions being directly transmitted to the photo-electric cell. In the form shown the light from a standard surface 2c illuminated by diffused light from e.g. an Ulbricht sphere 2 associated with a powerful source of light 1 is passed through a spectrometer 3 to a photo-electric cell 4 connected in series with the grid 5a of an audion 5 and with a battery P, a variable high resistance 7 and a potential divider 9 being connected between the grid 5a and a battery C. The filament 5b of the audion is heated by a battery V and the plate 5c is connected through a variable resistance 5f and an ammeter A to the anode battery B. A second audion 6 is similarly connected to the batteries C, V, B. A galvanometer 10a is connected between a tapping 10d and one end of a variable resistance 10b connected between tappings on the resistance 5f and a corresponding resistance 6f in the circuit of the audion 6, and is adjusted to give a predetermined reading. The sample 2d is then substituted for the standard 2c and the new reading of the galvanometer noted, the process being repeated for a succession of wavelengths. In a modification two photo-electric cells, acted on by light from the standard and sample respectively, are used, one being connected to each audion. It is stated that the product of the value of the resistance 7 and the ratio of the grid current to the anode current is made the same for each audion. If the width of the slits 3a, 3b is varied automatically by the means for varying the wavelength 3c the spectrum of the standard need not be directed on to the light sensitive cell alternatively with that of the test body.

Filed: 1966-09-16
Abstract: 1,092,190. Washing machines. ESSO RESEARCH & ENGINEERING CO. Sept. 16, 1966, No. 41552/66. Heading A4F. Apparatus for cleaning louvres of fluorescent lights comprises a washing tank 1 housing a basket 4, an agitator motor 16 capable of agitating the basket, a cleaning liquid tank 26, a rinse liquid tank 27, a pump 40 for transferring either the cleaning liquid or the rinse liquid to the washing tank and a filter 56 for filtering the cleaning liquid. The louvres are placed in the basket 4 which is pivoted by arms 6, 7 attached by pins 17, 8 and 18, 9 to a system of gear wheels. Wheels 12, 13 are rotated by the motor 16 via gear wheels 14, 15. On pressing the agitator motor starter button (61), Fig. 2 (not shown), current is fed to the coil (63) of a timer motor (not shown), the cams of which control microswitches (A<SP>1</SP>-I<SP>1</SP>). The microswitches (A<SP>1</SP>-H<SP>1</SP>) control the operation of magnetic or motorised valves (35-38, 43, 45) so that initially the pump 40 is switched on and a detergent such as "Stergene" (Registered Trade Mark) is pumped from the tank 26 through the line 33, 39, 41, 42 and an inlet 2 to the tank 1. Heaters 28 are disconnected from the electricity supply whilst the pump is running. After the detergent has been transferred, valves 43, 45 are opened and the cleaning liquid is continuously circulated through the centrifuge filter 56. At the end of the washing period, the valve 35 is opened and the valve 43 is closed so that the cleaning liquid is pumped back to the tank 26. The valves 45, 35 are then closed whilst 38, 43 are opened so that rinsing water is pumped from the tank 27 to the tank 1 whereupon the valve 38 is closed and 43, 45 are opened in order to circulate the rinse water. After pumping the rinse water back to the tank 27, the timer stops the agitator. A fan heater 23 supplies hot air through a duct 24 to dry the louvres and the heater 28 warms the tank of cleaning liquid. After a further period of time, the microswitch (I<SP>1</SP>) disconnects the fan heater 23, the heater 28 and the timer coil (63), thus reseting the apparatus for the next cycle. The cleaning liquid may be heated by steam or other hot fluid in pipes or coils passing through the cleaning liquid.

Filed: 1960-12-07
Abstract: 922,887. Transistor monitoring circuits. COURTAULDS Ltd. Dec. 6, 1961 [Dec. 7, 1960], No. 42070/60. Class 40 (6). [Also in Group XXXVI] A circuit for monitoring the magnitude of a variable parameter comprises two complementary transistors T 1 , T 2 , the base of one transistor being connected to a common base line, to which is applied a voltage derived from the variable parameter, through a variable resistor and the emitter of the other transistor being connected to a variable potentiometer. As shown in the Figure, the two transistors are biased so as to be non-conductive when the parameter to be measured applied to terminals A is within preselected upper and lower limits. If, however, the input current through resistor R 1  increases the voltage of the common base line L 1  becomes more negative with respect to the earth line L 2 , so that when the voltage on the base of transistor T 1 , determined by the variable resistor R 2 , reaches the preselected upper limit of the parameter, transistor T 1  conducts, causing the high limit alarm 1 to operate. The second transistor T 2  has its emitter bias regulated by potentiometer R 3  so as to be cut-off when the parameter to be monitored is above the low-level limit. However, if the input current through resistor R 1  decreases the voltage of line L 1  becomes less negative and the base of transistor T 2  becomes positive with respect to its emitter resulting in this transistor conducting and the lowlimit alarm 2 operating.

A method of testing fuel elements in a nuclear reactor comprises rapidly raising the temperature of fuel elements in a coolant channel while the reactor is operating at power so that a transient burst of fission products is emitted from any existing leaks in the fuel element sheaths into the coolant stream for detection by monitoring apparatus. The rate of increase of temperature should be at least 4  C./minute, the difference between the initial and final temperatures at least 4 C., and the final temperature at least 400 C. The temperature may be increased by reducing the coolant flow while the coolant pressure remains unaltered or by increasing the reactor power. Another method comprises increasing the coolant flow by increasing the speed of the coolant blowers, thus causing an initial drop in temperature, and then increasing the power of the reactor to restore the fuel elements to their initial temperature. Specification 897,450 is referred to.
