Title: Improvements relating to optical apparatus for imitating the colour of a light-scattering medium
IPC: G01J3/46
Filed: 1957-07-10
Abstract: 863,314. Comparing colours. NEDERLANDSE ORGANISATIE VOOR TOEGEPAST-NATUURWETENSCHAPPELIJK ONDERZOEK TEN BEHOEVE VAN NIJVERHEID, HANDEL EN VERKEER. Jouly 10, 1957 [July 16, 1956], No. 21885/57. Class 97(1) Apparatus for imitating the colour of a coloured sample of light scattering material comprises several coloured filters which are arranged so that a parallel light beam can pass through each of them in turn, each of the filters having an absorbing power which varies with distance in a direction perpendicular to the light beam, so as to vary the absorption in such a manner that each fraction of the beam travels through an amount of non-scattering colouring substance which is proportional to the length of the path of the corresponding fraction of the light scattered in the sample, and means for integrating the colours of the beam emerging from the last filter. In the form shown some of the parallel light from a lamp L and reflector P is deflected by inclined mirrors S 1 <SP>1</SP>, S 1  and S 2 , S 2 <SP>1</SP> so as to pass through a cylindrical lens CL into an integrating cube I having an aperture O through which the light as reflected by a coloured sample at M emerges. Parallel light from the reflector P which is not deflected by the mirrors S 1 <SP>1</SP>, S 1  and S 2 , S 2 1 passes through the diaphragms, D and differently coloured filter cells SI before passing through the lens CL into an integrating cube II from which it emerges at O after reflection at a white surface disposed at M. In this way, the colour of white light reflected from the sample can be compared with the colour of the coloured beam after reflection from white surface. The thickness of each filter cell SI varies continuously or stepwise with distance in a direction at right angles to the aligned diaphragm openings so that by moving one or more of the filter cells the colour of the light passing therethrough can be varied. Each filter cell may comprise a transparent vessel containing coloured liquid or it may be a coloured solid. The absorbing power of each filter may also vary in a second direction which is perpendicular to the first direction and also to the direction of the light beam. It is preferred that the absorption power of each filter shall vary in accordance with the theory of Kubelka-Munk as explained in the Specification.

Abstract: 695,884. Ploughs. MELLEN, A. M. Sept. 7, 1950, No. 22055/50. Class 6(i) A plough, or other earthworking structure, has the implement 40 pivotally mounted on a support B which is mounted upon an elevationally controlled draft connection of a vehicle, the upper portion of the support being connected to the power lift. The implement is shiftable about its pivot by an actuating lever 65 and pivoted control arm 85, there being connecting means between the control arm and a lower part of the vehicle, whereby upon elevation of the support the said connecting means moves the control arm about its pivot to actuate the actuating lever and thus shift the position of the earthworking means. In the construction shown, two plough units 40 are pivotally supported at 50 on a frame structure 35 which can be raised and lowered by means which include arms 20, lift rods 24, and crank arms 25. A cable 41 connected to the two units and passing around a pulley 43 on the structure 35 is for the purpose of raising any one unit as the other is being lowered. The pivots 50 are carried by members 54 adjustable laterally on shafts 36, 37, of the frame 35, and the connection is such as to allow the pivots to be inclined in either the vertical and horizontal planes. Each unit is connected by a link 60 to an arm 65 which swings about the lower shaft 36 and which carries a latch 70 for engagement with a member 35a of frame 35. The latch is under the control of a lever 85 which pivots on the arm 65 and which is connected by a cable 72 to a pivoted arm 74. A stop 80 is movable, by means accessible to the operator, to a position preventing rearward pivotal movement of either of the two arms 74. Operation. With the parts in the position shown in Fig, 1 the stop 80 is moved into the path of the arm 74 associated with the lowered plough. Upon raising the frame structure a tension is applied to the corresponding cable 72 with the result that the lever 85 releases the latch 70 and then causes the arm 65 to swing about the shaft 36 to raise the plough. After a certain degree of movement gravity assists in completing the reversal of the two units. Modifications are described and illustrated which incorporate variations in the latching means and in the mechanisms for actuating the bolt 80.
