[Also in Divisions C7 and C3] A water-soluble or -dilutable coating composition comprises a hydrophilic, thermosettable phenolic resol or aminoplast resin and a resinous material in salt form obtained by at least partial neutralisation of (i) a carboxyl group-containing adduct of an unsaturated fatty acid or ester and an alpha-beta-unsaturated dicarboxylic acid with (ii) an organic base where Y is methylene to butylene or -GH 2 - NR 1 -CH 2 -; R 1  and R 1 <SP>1</SP> are H, CH 3 , C 2 H 5  or CH 2 -CHR 2 -OR 3 ; R 2  and R 2 <SP>1</SP> are H, CH 3  or C 2 H 5 ; R 3  and R 3  are H, -(CH 2 -CH 3 - O-) r -H; or -(CH 2 -CH.CH 3 -O) x -H; and x is 0 to 6. (i) and (ii) may be partially condensed and neutralisation completed with ammonia or an organic nitrogen base. Specific bases (ii) are reaction products of polyamines with propylene oxide. In the adduct (i) up to 50% of the fatty acid or ester may be replaced by a resin acid or ester. The composition may contain a pigment and a water miscible organic solvent e.g. an olcohol, ketone or glycol ether or ether-ester and may have a pH below 7 e.g. 6. Numerous suitable materials or reactants for the various ingredients are mentioned. In specific Examples the resoles or aminoplast are derived from formaldehyde and (i) p-t-butyl phenol, (ii) 4,4,-bis(4-hydroxyphenyl)-valeric acid; (iii) a phenol obtained by alkane reaction of diphenylol propane and sodium chloracetate, and (v) melamine; (iv) is (i) etherified with methanol: the acid resins are (a) a reaction product of linseed oil and maleic acid having an acid number above 300 and (b) a reaction product of soyabean oil, dehydrogenated castor oil, linseed oil and maleic anhydride of acid No. 366, hydrolysed with water and diluted with 2-butoxy-ethanol: and the nitrogen base is N,N,N<SP>1</SP>,N<SP>1</SP>,N<SP>11</SP>-pentakis-(2-hydroxypropyl-)diethylene triamine or N, N, N<SP>1</SP>, N<SP>1</SP>, N<SP>11</SP>, N<SP>111</SP>-hexakis-(2-hydroxypropyl-)triethylene tetramine; or N,N,N<SP>1</SP>N<SP>1</SP>- tetrakis-(2-hydroxypropyl-)ethylene diamine. In Example 6 this last base and acid resin (a) are partially condensed and neutralisation completed with ammonia. Baked coatings The pigmented composition may be applied to the body to be coated by dipping or as a lacquer (in which the aminoplast rather than the phenolic resin should be used) followed by baking e.g. at 150 to 160‹C. In the embodiment illustrated in Example 6 where the acid resin and defined nitrogen base are partially condensed the compositions are usefully applied by electrophoretic deposition, the metallic body being dipped into a bath as anode and a voltage of 70 to 120 volts used.

Title: Automatic level control device for use in telecommunication systems
IPC: H04B3/12
Filed: 1970-10-09
Abstract: 1331768 Automatic level control; semiconductor circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 9 Oct 1970 [13 Oct 1969] 48159/70 Headings H3T and H4R In an automatic level control, a control signal adjusts a first impedance in one arm of a selfadjusting bridge which automatically adjusts the D.C. supply to the bridge and thus the impedance of a current dependent impedance connected in the bridge and forming the level control device in the path to be controlled, until a predetermined relationship exists between the values of the two impedances. As described the control is used to control the gain of amplifiers in a carrier frequency transmission path. A test frequency band is transmitted from one end of the path to a receiver at the other, which receiver if the received test signal deviates from the control range transmits instruction pulses over a separate line to the transmitter. The transmitter then sends a control signal to each gain control over the path to similarly vary the gain of each amplifier. The control signal may be a variable frequency, in which case the first impedance (Fig. 3, not shown) includes a pair of transistors which for each cycle charge and discharge a small capacitor (44). A large capacitor (48) to which it is connected functions as a variable resistor passing the charging current. Alternatively the control signal may be equally spaced pulses of variable duration in which case the first impedance (Fig. 4, not shown) comprises a resistor and series gate transistor rendered conductive for each pulse and a smoothing capacitor in parallel with the series combination. The figure shown shows a bridge with the first impedance 25 in one arm, the current dependent impedance 15, which is also in the negative feedback path of a transmission path amplifier 4, in a second arm and third and fourth resistors 33 and 34 in the remaining arms. A comparator 31 connected to junctions 37 and 38 and comprising transistors 35 and 36 responds to a potential difference between these junctions to control via a transistor 29 the voltage supply to the bridge in a direction to restore balance. Balance is achieved by varying the current through the bridge and thus the impedance 15 which may be a thermistor or incandescent lamp circuit &c. until the ratio of the resistance of this impedance to the value of resistance 25 equals the ratio of the resistances 33 and 34. In an alternative embodiment not detailed the impedances 15 and 25 could be in series in the same arm of the bridge which would be arranged to adjust until the sum of the resistances is a given value.

Abstract: 1322525 Pile fabrics TEIJIN Ltd 12 Oct 1970 [13 Oct 1969 25 May 1970] 48423/70 Heading D1K A pile fabric is made by feeding a sheet of thermoplastic yarns 1 into a stuffing chamber 3 to form corrugations 1', passing the corrugated sheet into a gap 6 defined by two conveyor belts 4, 4', where an electrically heated wire 5 crossing the gap 6 transversely and spaced slightly away from one of the belts 4, melts through the bottoms of the loops and simultaneously fuses them together to form a backing layer 8 and the loops to the backing layer to form a pile layer. The backing layer may then be strengthened by impregnating it with a foamed synthetic resin 15 from a supply tank 14 and hardening the resin with a heated roller 16. A vacuum nozzle 17 may be positioned opposite the supply tank 14 to draw the resin into fabric. The fabric may be formed with irregular loops of varying height (Figs. 3 and 4, not shown) by feeding the sheet 1 of varns irregularly into the stuffing chamber 3, or by creating a disturbance in the stuffing chamber 3. In an alternative embodiment (not shown), wires 5 may be positioned on both sides of the gap 6 and the emerging fabric sliced along the middle to form two cut pile fabrics:

A magnetostatic relay is used to control the current flowing in a pair of conductors. The relay, which is a combination of a magnetic amplifier and a transistor, has only two possible outputs, one of which is zero, and may be as described in Specification 871,623. Fig. 1 shows the relay used as a ringing stop device in a telephone network, a pair of wires A, B, being connected via transformer TR to the subscriber and having their other ends connected to an exchange (not shown). The magnetostatic relay SDE has five windings e1-e5, e1 being an optional winding for establishing the initial state of the relay. Windings e2 and e3 are control windings which are connected at Q but which are wound with opposite senses. To call the subscriber, an A.C. ringing current is passed from TA by connecting point SA to SA1 and SB to SB1, the circuit being SA1, C1, P, M, A, TR, ringing device, TR, B, N,.Q, C2, SB1. This produces an A.C. flow through e2 and e3, but does not affect the relay since the currents in e2 and e3 are equal and opposite. When the subscriber answers, D.C. current flows in a path comprising earth, R1, P, M, A, TR, subscribers instrument, TR, B, N, Q, e2, R3, -<SP>ve</SP> supply, thus producing a D.C. flow in e2 which triggers the relay SDE. This triggering actuates a device (not shown) to break connections PM, QN, and also to disconnect TA. The subscriber receives current through a circuit comprising earth, e5, R1, TR, A, his instrument, B, TR, R2, e4, -<SP>ve</SP> supply, the flow through e4 and e5 holding the relay on until the call ceases.

Abstract: 1352727 Detecting surface defects REDERIAKTIEBOLAGET NORDSTJERNAN 20 Oct 1971 [21 Oct 1970] 48810/71 Heading G1A In a device for detecting surface defects of a substantially smooth material 3 (e.g. scratches in steel), a laser beam is caused to scan the surface of the material by a rotating prism 3 and the scattered and diffracted light is collected by a lens system 4 to form a stationary diffraction pattern in a plane 6 containing a spatial filter which is so constructed that it blocks light due to the normal diffraction pattern of the material and only passes light due to surface defects on to a detector 9. Figs. 3b and 4b show examples of diffraction patterns from steel samples with and without defects (scratches). The spatial filter may comprise a simple opaque mask Figs. 6a, 6b (not shown) or it may be a photographic film that has been exposed to the normal diffraction pattern achieved during scanning or it may comprise a photo-chromous material which is darkened by the stationary normal diffraction image but which allows the transmission of the radiation due to the transient diffraction image deriving from surface defects. The detectors output Fig. 7 (not shown) may then be processed to sense sudden positive or negative pulses indicating scratches &c or dark lines or areas. The process may consist of separating the detector's output into two channels by means of polarization sensing elements. The detecting device can be connected to computers controlling the manufacturing or workingprocesses of the controlled material. The control can also be adapted to start cutting and sorting of the material to different lengths depending upon the defects present.
