Filed: 1974-03-20
Abstract: 1422098 Coated magnetic products TDK ELECTRONIC CO 20 March 1974 [20 March 1973] 12462/74 Heading B2E A magnetic recording medium comprises a magnetic recording layer containing acicular, single domain magnetic iron oxide particles having a cobalt content of 0.5 to 10% by weight and a ratio of Fe<SP>2+</SP> : Fe<SP>3+</SP> of 0.1 to 0.35:1, the layer having been treated so that a residual magnetisation is attained which is at least 85% of the saturated magnetisation and having been stabilised at a temperature in the range of room temperature to 60C. The medium may be obtained by treating a recording medium having a magnetic recording layer as above by passing the recording layer through a gap between a pair of magnets so that the residual magnetisation which is retained is at least 85% of the saturated magnetisation and then stabilising the induced magnetisation at a temperature from room temperature to 60C. The recording medium may be a tape, sheet, card or drum. In Example 1 120 parts of iron oxide particles containing 3.0% by weight of a cobalt component and having an Fe<SP>2+</SP> : Fe<SP>3+</SP> ratio of 0.25:1 as mixed with 150 parts methylethyl ketone, 150 parts methylisobutyl ketone, 30 parts vinyl chloride/ vinyl acetate copolymer, 10 parts polyurethane resin, 10 parts carbon black and 3 parts lubricant and applied to a polyethylene terephthalate film. It was subjected to a magnetic field orientation treatment, dried and calendered. The coated film was then magnetised by passing at a velocity of 20 m/min. through a gap having a width of 2.5 mm between a pair of strontium ferrite magnets which generated a maximum magnetic field of 3400 Oe in a longitudinal direction of the tape and the residual magnetisation of the tape was found to be more than 85% of saturation. The magnetised film was then exposed to hot air at 80-120C for one minute, cooled to room temperature and then cut to form tapes. The magnetic tapes were stored at 60C for two weeks until equilibrium states were attained. In the second Example a similar procedure was followed but the magnetic particles contained 3.6 weight percent cobalt and the Fe<SP>2+</SP> : Fe<SP>3+</SP> ratio was 0.23:1.

Abstract: 1,256,059. Locating the centre of gravity of a rotor. F. BONI [trading as F. A. S. E. P.], March 17, 1970 [March 21, 1969], No. 12706/70. Heading G1N. The unbalance of a vehicle wheel 2, Fig. 5 is determined by jacking up the end of the vehicle, rotating the wheel 2 by a motor and drive-wheel on a trolley 11, measuring the vibrations produced by the unbalance mass using an inductive transducer 20 in contact with the wheel support 10 and feeding the vibration signals to stroboscopic apparatus 16 to illuminate the same portion of the wheel, associated with the position of the centre of gravity, in each revolution. The transducer 20 comprises a coil 32, Fig. 6 attached to a plate 24 mounted on a rod 22, co-operating with U-shaped permanent magnets 34, 36 carried by a telescopic feeler rod 42 ending in a magnetic head 46 for attachment to the leaf-spring support 10, the magnets 34, 36 being supported by leafsprings 40. The vibrations of the wheel and support due to the C. G. not coinciding with the axis of rotation are repeated by the magnets 34, 36 and produce voltage signals in coil 32 representing the displacement velocity. These are integrated at 81, 83, Fig. 11 to obtain displacement signals, whose waveform is suitably modified and fed to measuring network 63. The displacement signals are further modified and fed to a monostable multi-vibrator 73, developing a synchronous pulse train whose leading edges coincide with a positivegoing zero value of displacement. These leading edges initiate pulses in transformer 95 which fire lamps 77 of the stroboscope 16, to light an area of the wheel, and the C. G. of the wheel is located on the diameter perpendicular to the diameter through the illuminated area. The pulses firing the lamps can be displaced by 90 degrees so that the illuminated area is on the C. G. diameter of the wheel.

Abstract: 1,068,432. Coated non-woven fabrics. BIGELOW-SANFORD, Inc. March 26, 1964 [Oct. 31, 1963], No. 13057/64. Heading B2E. [Also in Divisions B5 and D1] A non-woven fabric, which can be used as a backing in tufted-pile fabrics, comprises a batt of fibres intermixed by needling. The fibres of one or both surfaces are bonded together into a flattened and hardened condition, but the remaining fibres are unbonded. As shown, fibres of polypropylene alone or mixed with other fibres are fed from feedboxes 30 to garnets 31 which form them into webs which pass on to shoots 32. These shoots traverse back and forth over a conveyer element 33, e.g. a lowcount cheesecloth which remains part of the finished product. Alternatively, the cheesecloth may be omitted, and the layer of fibres supported for needling on a continuous moving belt of slats or the like. The fabric is passed through a needling machine 36 and a J-box 37 to heated rolls 38 and 39. The temperature of and time of contact with these rolls are sufficient to fuse the polypropylene fibres in a layer at each surface of the fabric, but to leave the interior of the web unfused. The surface layers may be bonded by spraying on a binder such as an acrylic resin or a curable latex instead of fusing. Other fibres that may be mixed with the polypropylene fibres are nylon, rayon, acrylic or polyester fibres. Carpets may be made by tufting pile-forming yams on to a backing of the above fabric, and then backcoating with a synthetic latex-base adhesive.
