Title: Improvements in or relating to the treatment of textiles
IPC: C09K23/00
Filed: 1930-08-16
Abstract: The treatment of textiles with liquids is effected in the presence of a water-soluble salt of an aliphatic primary or secondary amino monocarboxylic acid substituted on the nitrogen atom by a saturated or unsaturated fatty acid residue containing more than eight carbon atoms.  The salts may act as washing or dispersing agents.  In examples, (1) a washing preparation is prepared by stirring methylcyclohexanol and oleyl sarcosine sodium salt into water; the preparation can be used in conjunction with other washing agents, such as soap; (2) solvents such as glycol, oil of turpentine, acetone, methylcyclohexanone, or glycol monocresyl ether are used in admixture with oleyl sarcosine sodium salt as in example (1).ALSO:The treatment of textiles with liquids is effected in the presence of a water-soluble salt of an aliphatic primary or secondary amino monocarboxylic acid substituted on the nitrogen atom by a saturated or unsaturated fatty acid residue containing more than eight carbon atoms.  The salts may act as washing, wetting, dispersing, equalizing or softening agents.  In the examples, (1) viscose silk is dyed in a bath containing Benzo blue 2B, sodium sulphate, and stearyl sarcosine sodium salt; the latter salt may be added to the last rinsing water instead of to the dye-bath; (2) cotton warps are sized in a bath containing potato meal and oleyl sarcosine sodium salt; (3) a washing preparation for textiles is prepared by stirring methylcyclohexanol and oleyl sarcosine sodium salt into water; the preparation can be used in conjunction with other washing agents, such as soap or alkalies; (4) oleyl sarcosine is dissolved in caustic soda mercerizing lye; (5) solvents such as glycol, oil of turpentine, acetone, methylcyclohexanone, or glycol monocresyl ether are used in admixture with oleyl sarcosine sodium salt as in example 3; (6) cotton is dyed in a bath containing Cotton red 4B, sodium carbonate, sodium sulphate, and oleyl sarcosine; the latter may be replaced by oleyl glycine or oleyl a - or b -alanine.  Oleyl sarcosine, oleyl glycine, and oleyl a - and b -alanine are prepared by condensing oleic acid chloride with the appropriate aminoacid in the presence of an acid-binding agent.  Stearyl sarcosine is prepared similarly from stearic acid chloride and sarcosine.

The apparatus may control the size of diaphragm 57 automatically or manually in dependence on incident light intensity. Manual setting. For daylight operation, ring 4 is set manually to the required exposure time and the required diaphragm is set by ring 12. A rod 62 is moved out of engagement with a lever 63 during setting, such that pin 35 is moved out of the path of a stop 34. Lever 63 rotates lever 36 clockwise to close contacts 39 to energize an exposure meter 80 having a pointer 81 indicating the intensity of incident light. Clockwise rotation of lever 36 causes clockwise rotation of lever 43 to permit lever 25 to be urged clockwise by spring 26. Lever 68 actuates shutter plate 71 to expose window 76 for daylight photography and covering window 75 for flash-light photography. Automatic setting. For automatic daylight operation, ring 12 is adjusted until mark 14 is aligned with mark 3. Lever 63 holds the pin out of the path of stop 34. On depression of release shaft 86 member 51 is released until stop surface 78 encounters pointer 81. A pointer 73 indicates exposure times on a scale 74. Movement of member 51 adjusts diaphragm device 57 according to the light intensity. Exposure for flash-light exposures is provided by setting ring 4 to an appropriate exposure time and setting ring 12 with marks 13 and 3 aligned. In this case the exposure meter is de-energized by contacts 39.

Title: Data encoder
IPC: F15C1/00
Filed: 1965-06-14
Abstract: 1,081,194. Keyboard controlled encoders. SPERRY RAND CORPORATION. June 14, 1965 [June 25, 1964], No. 24964/65. Heading G4P. A character expressed in a first code, e.g. decimal, is entered via a keyboard into a fluidcontrolled data encoder where it is converted into a character expressed in a second code, e.g. binary. In the form shown, in which the encoder converts a decimal input into a binaryexcess three-code when a key (26, Fig. 1, not shown), for example the key representing the numeral 4 is depressed, flow from channel 22 (Fig. 5) in an upper plate 14 of the encoder to the channel 46 4  is permitted through a hole 44 in the key. From this channel the fluid flows into channel 60 in plate 16 (Fig. 6), where it divides into three directions. Firstly it flows to port 121 from which it drops into channel 96 in a lower plate 18 (Fig. 7), to pass through an OR gate 104 and into output channel 100. From this it rises back into plate 16 (Fig. 6), via port 81 to give output on the channel 71 representing a binary 1. Secondly, it flows along channel 60 to OR gate 82 and hence into channel 58 from which it rises via port 52 (Fig. 5) in plate 14 to flow along channel 50 and back into channel 68 (Fig. 6) in plate 16 to give an output representing 4. Thirdly, it falls via port 76 into plate 18 (Fig. 7), in which it flows along channel 92 to OR gate 102 and hence into output channel 99. It then rises via port 80 (Fig. 6), to give output along channel 69 representing 2. Hence depression of the key representing the number 4 gives outputs representing 0111 in binary excess 3 code. Depression of the other keys results in similar conversion to decimal form.
