Title: Improvements in and relating to colour photography
Inventor: BARRETT-GOWERS COLIN ANTHONY
IPC: G03B27/73
Filed: 1981-06-05
Abstract: A set of transparent screens for selecting the appropriate filters to obtain correct colours in a colour photographic print are formed from sheets of optically flat glass or acetate. Each screen includes a matrix of rows and columns of differently coloured regions, each of the regions in each of the rows having a constant percentage of one colour filtration material (such as magenta) and measured along the row an increasing percentage from one region to the next of another colour (such as yellow) whilst the proportion of the said other colour (yellow) is constant from the top to the bottom of each of the columns but the proportion of the said one colour (magenta) varies from one region to the next from the top to the bottom of each of the columns. The two other screens incorporate the third filtration colour (cyan) in turn with each of the other two (magenta and yellow) colours. Thus one has varying percentages of magenta and cyan on the other varying percentages of yellow and cyan. A decoding chart plots the different colour percentages over each filter. Sufficient neutral density material may be incorporated into each coloured region to ensure that all regions have the same light transmission characteristics. The method involves exposing a negative with the magenta and yellow screen in contact with the negative and selecting the most correctly coloured region in the print so produced. The appropriate magenta and yellow filter may then be selected and fitted in the enlarger to obtain a correct overall exposure. The method is repeated with the other screens if cyan is required in the final filtration.

Patent GB-2140131-A (GB)
Title: Improvements in and relating to electrically operated valves
Inventor: JOHNSON DOUGLAS
IPC: F16K31/04
Filed: 1984-05-14
Abstract: An electrically operated valve (such as for controlling gas flows for example) having very low power consumption is described. The valve is opened by electrical energisation of a motor 26. Through a gear box, this causes a plate 20 to pivot in a clockwise direction, thus raising a rod 14 against a spring (not shown) and opening the valve. The plate 20 operates a plunger 30 of a microswitch 32 which interrupts the power supply to the motor 26. At the same time, the plate 20 is latched in the clockwise position by a permanent latch 34. The latter is of a type whose magnetic field can be interrupted by electrical energisation. When electrically energised, therefore, the latch 34 releases the plate 20 which thus turns in an anticlockwise direction under the influence of the spring, and closes the valve. As the plate 20 moves anticlockwise, the released microswitch 32 switches off the energisation to the latch 34. No power is thus consumed in holding the valve either in the open or in the closed position. <IMAGE>
