[Also in Division C4] A matrix 2 comprises rows and columns of holograms each formed by interference between a coherent reference beam 19 and a selected combination of coherent object beams representative of a binary code defining the co-ordinates of an elementary area of the matrix. Illumination of the matrix 1 by a reconstructing coherent beam perpendicular to the hologram plate gives rise to an undiffracted component 47, Fig. 3, and a first order diffraction component 48 reforming an image which is detected by means 38-41, Fig. 3, which convert the image into a parallel binary signal which reproduces the code of the elementary area. The reconstructing light beam is transmitted by a flexible light guide 26 moved by hand across the hologram matrix to give the desired trace. The undiffracted component is used to give a visual display of the trace. For this the source 20 of the light pen generates red or near infrared light rays which illuminate a photo-chromic plate 35 back-illuminated with ultraviolet light. An ultraviolet filter 34 is located in the undiffracted beam path 47 between the matrix 1 and photochromic plate 35. The binary coded signal produced may be used as data feed for a computer.

Abstract: 1,216,148. Feeding material to endless conveyers. SCHUBERT & SALZER MASCHINENFABRIK A.G. 10 Dec., 1968, No. 58519/68. Heading B8A. [Also in Divisions D1 and G1] A method for the automatic mixing of fibrous material components in a predetermined mixing proportion is characterized in that the removal of fibrous material from the bales B1-B11, B1<SP>1</SP>-B11<SP>1</SP> of the individual components takes place successively independently of the number of bales in amounts corresponding to the desired mixing proportion and determined by a given programme. Apparatus for carrying out the method comprises a removal device for taking fibrous material from the different fibre bales, a quantity measuring device associated with the removal device and a programme control for the mode of operation of the removal device dependent on the measuring device. The removal device is mounted on a carriage 1 which moves along rows of bales. Fibrous material comprising one component of the desired mixture is removed from the bales containing that component and is deposited in containers 5, 51 which travel with the carriage. The removal device travels across the specified bales until the required proportion of the fibrous material is obtained in the containers 5, 51. The containers 5, 51 then travel along the row of bales to an emptying position over a conveyer 6 and the fibrous material is deposited on the conveyer. The carriage then conveys the removal device to the bales containing the fibrous material of another component of the desired mixture and the procedure is repeated. A system of cams is described for the operation of the motors associated with the various parts of the apparatus, e.g. motor M1 for driving the carriage 1, motors for moving the removal device up and down relative to the bales, and motor M6 for tilting the containers 5, 51 to deposit the fibrous material on the conveyer. The removal device may comprise grippers operating from above or rasps or plucking fingers operating from below. The quantity measuring device may be in the form of a weighing device, a frequency counter of the removal strokes of grippers or of the revolutions of the rasping rollers, or an optical measuring device. In a further embodiment, the quantity measuring device can be fixed at the outlet-of a conveyer fed by the removal device. The removal device can be modified to operate any number of rows of bales by being made to travel at right angles to as well as along the rows of bales. The programme control is provided with a switching device consisting of contacts co-operating with switches wherein at least one switch track is provided for limiting the respective range in which the individual fibrous material components are positioned, one for limiting the total movement of the carriage, and one for limiting the different zones on the fibre bales for the removal of layers of fibrous material from the bales. The fibre com ponents are fed to an opener.
