Title: Sampling of materials and apparatus therefor
IPC: G01N1/20
Filed: 1950-09-25
Abstract: 683,168. Sampling. DIRECTIE VAN DE STAATSMIJNEN IN LIMBURG. Sept. 25, 1950 [Oct. 12, 1949], No. 23394/50. Class 58 An apparatus for automatically taking a multiplicity of small sample "increments" from the interior of a moving stream of heterogeneous material comprises one or more scoops 3 in the form a a tube having one end partly closed to form the collecting part of the scoop and to leave an end receiving orifice therein and mounted for rotation so that the orificed end can pass in an arcuate path into and out of a stream of material and in a direction opposite to the direction of movement of the stream, the sample being taken from the medial part of the arcuate travel, the axis of rotation being so arranged that the receiving orifice of the scoop lies in a plane which is tangential or substantially tangential to the locus of the centre of the orifice about said axis. As shown, a hollow discharge tube 2 with a detachable scoop 3 connected in alignment therewith is mounted for rotation with a horizontal shaft 1 disposed over a belt conveyer 9, the plane of rotation of the discharge tube and scoop being inclined to the vertical. By means of a motor furnished with a time-relay and a circuit breaker, the entire assembly being housed in a casing 10, the arm is given an intermittent rotary movement in such a manner that the scoop is swung at predetermined intervals through the material in a direction opposite to that of the movement of the stream. When the scoop is raised, the automatic device 4 is put in operation by the lever 8 so that the motor is stopped with the scoop in an inverted position, and immediately before the scoop and discharge tube come to a standstill, a knocker 5, which through the arm 5a is connected to a sleeve 5b rotatable relatively to shaft 1, and is rotated upwards by the rotating tubes, passes its top centre position with respect to the shaft and thereupon rotates downwards under gravity and strikes against the side of the discharge tube. This striking blow causes any material clinging within the scoop to free itself and to discharge through the discharge tube clear of the conveyer belt, into a pipe 6 delivering to a receiver 7. Where a cake of material has been formed as aforesaid closing the receiving orifice, this can be thrown off by the initial impact of the tubes with the knocker 5 soon after the scoop leaves the stream of material. After discharge the scoop and discharge tube are ready to commence a further revolution initiated by the time-relay. In one form of the scoop the closure plate 13 of the tube is flat and as shown in Fig. 2b it is formed so that a medial portion 13b of the plate immediately behind the orifice 11 is inclined towards the orifice from the trailing part 13c of the plate which forms the bottom of the collecting portion of the scoop. The orifice 11 is formed in the leading portion 13a of the plate which is in a plane tangential or substantially tangential to what in use is the locus of the centre of the orifice.

Title: Improvements in or relating to colour photography
IPC: G03C7/20
Filed: 1932-08-29
Abstract: 406,663. Colour photography. BAKER, T. T., The Hut, Hatch End, Middlesex, and DUFAYCOLOR, Ltd., 19, New Bridge Street, London. Aug. 29, 1932, Nos. 24136/32 and 17733/33. [Class 98 (ii).] A method of producing a composite coloured print from a master colour-screen record having two or more part images corresponding to the colours of the screen comprises the steps of preparing two prints from two of the part images, one being on a light-reflecting base, such as paper, and being coloured, e.g. by toning, in a colour complementary to the colour of the corresponding record, and making from the other print an undeveloped gelatin print pigmented in a colour complementary to the colour of the corresponding record, superposing this print in register on the first print and developing it. For the third print in the case of three-colour records, a print is made on a strippable base, coloured in a colour complementary to the third record, applied in register to the first print, and the base stripped off. A positive is first prepared by reversal from a negative on a film bearing a screen of red, green and blue elements. Two holes are punched in the film for registration purposes and it is printed in succession on to three pieces of bromide paper sensitized respectively for blue, green and red and having similar registration holes, the transparency being reversed when making the red print. The colour of the printing light used corresponds in each case to the colour of the elements of the negative to be printed. The time of exposure may be determined by measuring the density of the negative by means of a light sensitive cell. The prints are then developed and reversed and the print on blue sensitive paper is toned yellow, e.g. with lead acetate and potassium ferricyanide followed by treatment with potassium bichromate. The print on green sensitive paper is printed on pigment paper, for example, that known under the Registered Trade Mark '' Carbro," and the pigment image is applied to the yellow toned print and developed. The third print is made on a paper with a strippable backing and toned blue, e.g. with ferrocyanide and iron alum, and is applied to the superposed prints. Each print is provided with a third hole and a registering board having three upstanding pins is used to facilitate register. In a modification, the third print is made on a celluloid backing which is not stripped off. In a further modification, two prints only are used and are exposed in superposition using a yellow filter, e.g. one dyed with the ammonium salt of aurophenin, or uranin. The three prints may also be made simultaneously if a known type of light-splitting device is used, the prints being made under appropriate filters on a single paper strip coated with a panchromatic emulsion. Specifications 175,003, 198,745, 217,557 and 322,432, [all in Class 98 (ii)], are referred to.
