Abstract: 388,180. Heating by circulation of fluids. REISS, A., 307, Eckenheimerlandstrasse, and CHRIST, J. P., 26, Blechackerstrasse, both in Frankfort-on- Main, Germany. Jan. 18, 1932, No. 1516. Convention date, Dec. 3, 1931. [Class 64 (ii).] In a steam heating system, the consumers are divided into groups, of which one is supplied with steam from the supply conduit, the next with a mixture of such steam and exhaust steam from the first group, and the third with exhaust steam from the preceding groups. Steam is supplied directly from a main 2 to any consumer 1, the outlet of which is connected to a separator 3 from which water of condensation passes by pipe 5 to a separator 6. The outlet of the second consumer 7 is connected to a separator 9 which discharges into the pipe 5, and the inlet is supplied with mixed steam drawn from the main 2, and from the separator 9 by an injector 10. The steam spaces of the separators 3, 9 are connected by a pipe 13. The injector 10 is regulated for a minimum consumption of steam from the main 2, and additional steam is added as required by means of a jet 16 when valve 19 is opened. The third consumer 20 is supplied by a similar injecting apparatus 21, 22, the pressure supply being derived from separator 9 through pipe 23 and suction steam from separator 6 through pipe 26. The separators 6, 9 are provided in known manner with valves 28 each controlled by a diaphragm 30 subject on its two sides to the pressure in the suction space of the injector, and to the pressure at the inlet to the consumer respectively. In a modification, Fig. 3, (not shown) the main heating groups may be divided into sub-groups.

Patent GB-691970-A (GB)
Title: Method of and means for automatic colour selection
IPC: G01J3/46
Filed: 1950-01-20
Abstract: 691,970. Photo-electric detection of particular colours. ETABLISSEMENTS E. BELIN. Jan. 20, 1950 [Jan. 27, 1949], No. 1617/50. Class 40 (iii). An arrangement stated to be useful in colorimetric analysis, copying documents and the control of textile machinery comprises means for scanning a coloured object by a pencil of white light and for producing an electrical response which is between zero and a predetermined value when the pencil scans an area of a particular colour and its lighter shades but at other times is of greater value. The apparatus involves (a) the splitting of the beam after reflection from (or transmission by) the object by a constantly rotating shutter 12 with reflecting teeth; (b) the dispersion of the part beams by prisms 16, 17, respectively; (c) the selection by an adjustable mirror 24 of the portion of the spectrum emerging from 16 that corresponds to the chosen colour for reflection to a photo-cell 23 and the transmission of the remainder to a photo-cell 22; (d) the transmission of the part of the spectrum emerging from 17 that corresponds to the chosen colour to a photo-cell 26; (e) the balancing of the difference between the outputs of photo-cells 22, 23 against a voltage derived from the output of photo-cell 26. When the adjustments are correct, the resultant output for the pure chosen colour is zero and for its lighter shades is within predetermined limits. For black, white and other colours, the output is greater than this. Circuit arrangements, Fig. 4. Photo-cells 22, 23 act in opposition on an amplifier 30, the output of which is further amplified and then rectified so as to produce a voltage drop in a resistor 40. This voltage is zero when the chosen colour is being scanned but it is also zero when the colour scanned is black. To compensate for this, the voltage drop across 40 is added to opposing voltages developed across resistors 48, 54, the former resulting from simple amplification and rectification of the output of the photo-tube 26 and the second resulting from further treatment of this output in a non-linear circuit 50. This circuit consists of a tube, the grid of which is normally biased negatively until the rectified voltage developed across resistor 49 overcomes the bias. The valve current then rises rapidly. For the chosen colour, the joint voltage across 48 and 54 is zero and for lighter shades of the desired colour the resultant voltage opposes the voltage across 40 so that the resultant of all three voltages varies from zero for the desired colour to a limited value for white. For black and all other colours the output is distinguished by its greater amplitude.
