Abstract: 396,104. Softening water. AKTIEBOLAGET FILTRUM, 2, Norrmalmstorg, Stockholm. Jan. 23, 1933, No. 2128. Convention date, Feb. 1, 1932. [Class 46.] In base-exchange water-softening apparatus regenerating solution is introduced into a layer of water located above the base-exchange material in such manner as to set the laver in rotation without disturbing the material and thus secure a uniform distribution of the regenerating solution. In the apparatus the hard water main 14 has valved connections through pipes 15, 16 to the upper end of the treating container 10 and the soft water main has similar connections through pipes 22, 21 with the lower end of the container. The pipes 15, 22 have valved connections to a drain pipe 36. A rising pipe 37, open at the top, is also connected to the drain pipe, and a testing cock 40 is provided. Regenerating solution is drawn from a container 29 by water from the pipe 15 which is passed through'an ejector 27 and a pipe 26. The upper end of the pipe 26 is above the base-exchange material in the container 10 and is connected there to a distributing system consisting of four radial pipes 30 having lateral outflow openings, preferably inclined upwardly, so that the inflowing solution causes the water with which it becomes mixed to rotate. Baffles 32 may be arranged below the pipes 30 so as to prevent the water between the pipes and the baseexchange material taking part in the rotary movement. A pump may be used instead of the ejector 27.

Abstract: 694,889. Electric indicating systems. BRITISH INSULATED CALLENDER'S, CABLES, Ltd. Feb. 5, 1952 [Feb. 6, 1951], No. 2919/51. Class 40 (i). The surface of a long continuous moving article, e.g. the cotton insulation wound on a conducting wire, is examined by a feeler blade having its edge transverse to the direction of movement. The feeler movements are translated into corresponding electrical variations and used to operate a pointer indicator, or serve to sound an alarm and, or, stop the machine applying the cotton covering, if the irregularities exceed a predetermined value. As shown, the cotton covered wire 1 is fed over guide blocks 2 and is pressed by a light spring 6 against the upper edge of the feeler blade 4 which is disposed between the adjustable guides 2 so that its inclination to the direction of movement of the wire corresponds to the angle at which the helical cotton windings are wound on the wire. The feeler blade is carried by a bridge 8, Fig. 2, 3, the side pieces of which are secured to the underside of a soft iron disc-like armature 9 which is mounted on adjustable spring arms 10. The feeler movements caused by the surface irregularities of the wire are thus transmitted mechanically to the armature which produces corresponding voltage variations in a coil system 14 disposed in a case 11, secured to an adjustable block 12. The transducer output may actuate a pointer indicating the magnitude of the irregularities, or, as shown, in Fig. 4, may be fed by way of an amplifier V1 to a diode V2, which passes the amplified 'signal only if it exceeds a predetermined value, in which case the signal is further amplified at V3 and actuates a relay 20 through a rectifier 19, the relay operating an audible or visible alarm or serving to stop the machine applying the cotton insulation to the wire.
