Abstract: 1,233,494. Automatic concentration control. J. L. URBAIN. Sept. 18, 1969, [Sept. 23, 1968; June 18, 1969], No.46012/69. Heading G3R. The degree of activity of an ion-exchange resin is detected by comparison of electrical measurements made with two pairs of electrodes at different levels in a bed of the resin, any difference being applied to a diode-capacitor delay circuit to initiate re-generation through an amplifier. In Fig. 1, electrodes E 1 -E 4 , forming part of an A.C. bridge circuit, are arranged as pairs at different levels in a water softener containing an ion exchange resin which gives up sodium ions and fixes calcium ions from the water. When the resin becomes charged with calcium ions down to the level of the upper electrodes E 1 E 2 , the bridge becomes unbalanced to produce an output which is rectified at D and, when this is sufficient to overcome a bias from a potential divider R 2  R 3 , an output is produced by a transistor T. This output is applied to a diode resistor-capacitor delay circuit D 1  C 3  so that, if the condition sensed by electrodes persists, a relay R e  is energized when the threshold of a high gain amplifier AH 1  is reached. Energization of the relay starts a motor M which operates a cam N 2  to initiate regeneration. Motor M also operates a cam N 1  to change over contacts M 1  so that the supply to the detector circuit is disconnected and the operation of the motor made dependent on a contact M 2  which is operated by a timer J to stop the motor after a time sufficient for regeneration. Use of diode D 1  ensures rapid discharge of condenser C 3  in the interval to prevent errors due to residual charge. A switch I permits the initiation of regeneration to be over-ridden. Condensers C 1 , C 2 , C 4 , C 5  and a diode D 2  assist stability and/or provide protection. In a modification, a resin acts as a dielectric between electrodes in a resistancecapacity bridge circuit detecting the need for regeneration.

Abstract: 1,266,921. Laminated tubular film. ALGEMENE KUNSTZIJDE UNIE N.V. 17 Feb., 1969 [17 Feb., 1968], No. 8485/69. Headings B5A and B5B. [Also in Divisions F2 and H1] A tubular film has a wall having at least three layers which are formed alternately of different polymers and which, as exposed in a transverse cross-section of the tubular film, have at least over part of the film's circumference a spiralling shape, the layers defining the inner and outer wall surfaces being each formed of a single polymer. The spiralling part of each layer may extend through an angle of at least 360 degrees. The thickness of at least one of the surfacedefining layers may differ from, and may be at least 50% thicker or thinner than, any one of the layers of spiralling shape. To make such a tubular film in which the surface-defining layers consist of different polymers, two streams of different polymer are fed, Fig. 1, via adjacent passages 20, 21 respectively to annular chamber 14 between housing 3 and rotor 6. The streams, rotating side by side with rotor 6, flow through chamber 14 and are extruded through an annular slot 17 to form the film 30, Fig. 3. The outlets 25, 26 of passages 20, 21 are elongated in a direction parallel to the axis of rotation of rotor 6. Alternatively, the two polymer streams may be fed into one end of the annular chamber, one stream being eccentrically disposed with respect to the chamber's axis and being surrounded by the other stream, or two polymer streams may be fed through a stationary mandrel to an annular chamber formed between the mandrel and a rotatable housing surrounding the mandrel. To make a film in which the surface-defining layers are formed of the same polymer, two streams of different polymers are fed, Fig. 4, into one end of an annular chamber between rotor 37 and housing 39 via ports 40, 41 respectively. The two streams, one surrounding the other, are rotated and fed along the chamber to be extruded through an annular slot. The extruded tubular films may be inflated.

Abstract: 1289025 Generating phase displaced waves AGENCE NATIONALE DE VALORISATION DE LA RECHERCHE 12 Aug 1970 [14 Aug 1969] 38920/70 Heading H3T [Also in Division H2] Phase displaced triangular waves and sine waves formed from the displaced waves are produced either by adding oppositely phased triangular waves to D.C. bias voltages and selecting the maximum and minimum values over different parts of the cycles or by adding its oppositely phased triangular waves of two or three times the desired output frequency D.C. has voltages and selecting different portions of the combinations during different parts of the cycle. In Fig. 1 the input wave E is formed into the waves F, G, H and I. Between O and # the larger value of F and G is selected and between # and 2# the smaller value of H and I is selected so that the output wave T, displaced by #u, is produced. The displacement produced is dependent on the D.C. level of waves F to I and it is shown that for a phase shift # the displacements are - V 0 , V 0  - A 0 , V 0  and A 0  - V 0 , where A 0  is the peak-to-peak amplitude and V 0  = A 0  x (#/#). In Fig. 2 the triangular wave E is combined, in the appropriate signs, with V 0  and in 8 and 28 with A 0 . Diodes 12 and 13 select the maximum and 32 and 33 the minimum, switching between the two being effect at 17 at the 180 degree point under the control of the waveform C so that the displaced wave and a corresponding wave of opposite polarity are available at the outputs. Fig. 3 (not shown) illustrates the application to a phase displacement of 180 degrees. In Fig. 4 the input wave E1 is of twice the desired output wave frequency and from this is formed the waves I1, F1, H, or G1 and rectangular control waves (Fig. 5, not shown). The control waves select L, M, N, O, P and Q, R, S, T, U, these being two waves displaced with respect to each other. The control waves are produced in Fig. 6 (not shown) from the input wave by a counter (44) controlling changeover switches 45, 46. Fig. 7 illustrates a 3-pulse generator using an input triangular wave E2 of three times the desired output frequency from which are formed waves H2 and F2. The output waves R, S and T are formed from parts of E2, H2 and F2. using selecting signals C1R, C3R and C. The lettering on the output triangular wave R indicates the parts selected. Fig. 10 (not shown) illustrates the use of a ring counter (85) and logic gates (86) to control changeover switches (87, 88, 89) selecting the parts of the waveform for the three phases R, S, T.
