Abstract: 1,227,532. Tanning leather. NATIONAL RESEARCH DEVELOPMENT CORP. Aug.15, 1968 [Aug.19, 1967], No.38315/67. Heading C6C. Leather is tanned by a multiple tanning process comprising first treating it with a basic salt of a multivalent metal, e.g. basic chromium sulphate in aqueous solution, then with a water-soluble salt of a dibasic organic acid in which the carbacyl groups are connected by a chain having seven or more carbon atoms, the organic acid salt being one that forms an alkaline solution in water. In carrying out the process, the leather is immersed in aqueous solutions of each of the reagents in turn. In a first example, sodium sebacate is used as the second reagent, the total amount used being 10 per cent by weight of the shaved weight of the leather. The preceding chromium sulphate bath contains sufficient sulphate to give between 1À5 and 3À5 per cent by weight (calculated as metal oxide) based on the weight of the leather. The leather is neutralized with sodium bicarbonate to bromocresol green between the chromium sulphate treatment and the sodium sebacate treatment. The leather may be further treated with chromium sulphate after the sodium sebacate treatment; if desired, prior to washing and drying. In a second example, 33 per cent by weight of the leather, of basic chromium sulphate (equivalent to 1À5 per cent by weight Cr 2 O 3 ) is used in the first bath. The leather is then aged for 24 hours, washed and neutralized with 0À75% by weight of the leather of sodium bicarbonate. 5 per cent by weight of the leather of an ammonium salt of di-oleic acid is then added to the exhaust liquor and the leather immersed in this, after which the treated leather is further treated with chromium sulphate. A basic salt of aluminium, zirconium or cerium may be used in place of the chromium salt used in the first and further treatments.

Abstract: 1,231,445. Pipe-laying apparatus. IMPERIAL CHEMICAL INDUSTRIES Ltd. 19 Nov., 1969 [3 Dec., 1968], No. 57273/68. Heading F2P. A method of laying a land drainage tube comprises transporting a flat foil over the land, feeding the foil to a crimping device wherein at least one edge of the foil is crimped, twisting the crimped foil into an overlapping spiral tube and deposting the tube upon the land, the foil being crimped, twisted and deposited at a rate proportional to the rate of transport over the land. The crimping results in small gaps at intervals between the overlapping edges of the foil, through which water can drain from the soil. In a preferred embodiment a tractor drives a mole plough 4 through ground 5 to form a trench in which the drainage tube is laid. Framework 1, 2 and 3, is attached to the tractor and supports a rotatable cage comprising side members 8, a top plate 9 journalled in bearing 6, and a combined pulley and bush 11 journalled in bearing 7. Mounted between side members 8 is a spool 12 carrying foil 13, a pair of guide rollers 14 and a pair of crimping rollers 15, embossed to provide a herringbone or other crimp pattern to the foil, and driven by cog 16 which engages circular toothed track 17. Thus as the cage is rotated by a belt drive from pulley 18, which is driven by the land wheels of the tractor, to pulley 11, cog 16 and hence crimping rollers 15 are rotated. The rotation of rollers 15 and the forward movement of the tractor causes foil to be pulled off spool 12, crimped between rollers 15, and helically wound by the rotation of the cage into an overlapping tube which passes into the trench formed by mole plough 4. The drive ratio between the tractor and the cage may be varied in order to control the extent of the overlap of the foil. The foil is preferably of plastics, such as rigid polyvinyl chloride, A.B.S. (acrylonitrile-butadiene-styrene) resins, polypropylene or polystyrene, but other materials, e.g. metal, may be used. Preferred crimping patterns are illustrated in Figs. 5-7 (not shown).

Abstract: 1,251,453. Cathode-ray tube circuits. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 29 May, 1969 [17 June, 1968], No. 27244/69. Heading H4T. [Also in Divisions C1 and H1] A degaussing arrangement for the picture tube of a colour television receiver comprises a resistor having a positive temperature coefficient of resistance (PTC) connected in series with the parallel arrangement of a resistor having a negative temperature coefficient of resistance (NTC) and a degaussing coil wound around the picture tube the two resistors being in thermal contact. In operation, when an A.C. voltage is supplied to terminals 4, 5 (Fig. 1) a heavy current flows initially through the PTC resistor 1 and the degaussing coil 3 due to the low resistance of the PTC resistor and the high resistance of the NTC resistor 2 when cold. As the temperature of resistor 1 increases due to the current flow its resistance also increases whilst that of 2, due to the heat communicated from resistor 1, decreases until the small current finally passed by the, now high, resistance of the PTC resistor 1 is shunted by the, now low, resistance of the NTC resistor 2 which is made lower than the resistance of the degaussing coil 3. Thus, the A.C. current flow through the degaussing coil 3 is reduced to substantially zero to effect a degaussing cycle, the parameters being selected so that this cycle is completed within about five seconds. The PTC resistor consists of a semi-conductive barium titanate ceramic comprising e.g. (by weight) 65% to 70% BaCO 3 , 28% to 30% TiO 2 , 0À1% to 3% SiO 2  and less than 0À5% of La 2 O 3 ; Nb 2 O 5 , Sb 2 O 5  or Bi 2 O 3 . These are mixed by wet milling and the mixture calcined at 1200‹C. for two hours, pressed into pellets and fired at about 1350‹ C. in air for one to two hours. The fired pellets are then provided with electrodes comprising e.g. silver, made by painting a silver paste on opposite surfaces of the pellets and firing in a nitrogen atmosphere, or, nickelphosphor alloy made by electroless plating. The Curie temperature may be raised by substituting lead for some of the barium and may be lowered by substituting strontium for some of the barium and tin or zirconium for some of the titanium the low Curie temperature resistor being employed when a fast degaussing cycle is required and the high Curie temperature resistor when a relatively large degaussing current is employed. The NTC resistor may comprise e.g. (by weight) 30% to 38% M n O 2 , 50% to 60% Co 2 O and 2% to 3% CuO, mixed, calcined at 900‹ C. for one half to one hour and fired in air at 1300‹ C. for one to two hours. The composition may be modified by incorporating Cr 2 O 3 , NiO and TiO 2 . Electrodes may be added by similar methods to those employed with the PTC resistors. Fig. 4 shows a disc-type PTC and NTC resistor 15 and 16 respectively the inner electrodes 17<SP>1</SP> and 18<SP>1</SP> of which are soldered at 19 to maintain good thermal contact. A thin metal sheet between these electrodes provides a common terminal and lead wires are soldered to the other electrodes 17 and 18.

The roller 12 is driven in common with the carding machine, and is geared to drafting rolls 27 which form the input to a drafting zone. Rolls 29 which form the output of the zone, are driven by a variable speed motor 31. The rolls 27, 29 are coupled to tachometer generators 35, 37 which are connected to a draft control device 39. A store 40 has photo-electric relays 41, 42 for monitoring the level of the sliver and providing signals to the controller 44. A receiver 49 is driven by a motor 51' whose speed is variable. The transducer 15 produces pulses which indicate fluctuations in thickness of the sliver, these signals being fed to motor 31 which varies the degree of draft to reduce variations in thickness. The speed of the receiver 49 is altered in the same sense as the rolls 29, a resistor 60 providing a delay effect. The signals from the relays 41, 42 are imposed on the signals from the device 19 to maintain a steady level of sliver in the store. The device 19 varies the armature currents of the motors 31, 51', while the device 44 controls the field of the motor 51'. The draft control device 39 compares the signals from the tachometer generators 35, 37 and delivers pulses to the motor 31 whereby the required degree of draft is maintained by the control device 19. In a modification, the carding machine is driven by a variable speed motor, a pair of presser rollers being used to supply sliver to a store whose ouput is associated with a draft assembly. The input rolls 27 are now driven by the motor 31 while the rolls 29 and receiver 49 are driven at substantially constant speed, Figs. 3, 4 (not shown).
