March 30, 1961 [March 30, 1960], No. 11766/61. Class 140. A process for the production of a non-woven fabric in which a fleece of loose fibres is passed between a pair of rollers and is impregnated with a binding agent in the form of a foam which is fed to the gap between the rollers, is characterized in that at least the roller with which the binding agent is in contact has a partially raised surface to reduce the area of contact between the roller and the fleece. As shown, a fleece 11 of loose fibres is led to a pair of rollers 13, 14 on a conveyer belt 12. The surface of roller 13 is smooth but that of roller 14 is partially raised, i.e. embossed with a gridlike pattern of intersecting grooves. The fleece passes over roller 13, through the gap between the rollers and under roller 14. A foamed binding agent 15 is fed into the nip between the fleece and roller 14. After passing through the nip the impregnated fleece at first sticks to roller 14 but becomes detached at 16, the interruptions of the surface of roller 14 aiding the detachment of the fleece therefrom. Roller 13 may optionally also be embossed with a pattern, the same or different from that on roller 14. By use of an embossed roller as above any need to prestabilize the fleece by surface treatment with adhesive is obviated and improved evenness of impregnation is achieved. Specification 716,178 is referred to.

Title: Garments having durable antistatic properties
IPC: A41D31/00
Filed: 1969-03-05
Abstract: 1,261,791. Antistatic garments. TEIJIN Ltd. 5 March, 1969 [23 April, 1968; 18 June, 1968; 27 July, 1968; 25 Sept., 1968], No. 11834/69. Heading A3V. [Also in Divisions B5, C7 and D1] A garment having durable antistatic properties comprises an outer fabric and a lining or interlining of fibrous material at least part of which contains at least .01% by weight of an electrically conductive fibre comprising a substrate fibre with an electrically conductive coating, the fibre thereby retaining the functional properties of textile fibres. The conductive coating provides the antistatic properties as well as not being detrimental to said functional properties which include elasticity, subjectability to spinning, twisting, crimping, weaving, knitting and being able to withstand abrasion, tensile and bending stresses, scouring, dyeing and washing. The conductive coating, which may be of metal, metallic oxides or carbon, may be formed on the substrate fibre by direct application of a polymeric binder solution or emulsion of synthetic resin containing finely divided metal or carbon black, or alternatively, the coating can be formed by chemical plating or, in the case of metals, by vacuum evaporation. A top coating of an organic polymer may be applied on the conductive coating. The coating may also be strengthened by electroplating. The lining or interlining may contain only conductive fibres or a mixture of ordinary and conductive yarns mix-woven or mix-knitted together. It may also be formed by adhering or sewing the conductive fibres to a lining or interlining of ordinary fibres. The garment may be formed from an outer fabric of ordinary textile fibres which are of woven or knitted materials and forming laces or nettings, to which the lining or interlining containing the conductive fibres is bonded by adhesive or foam. Alternatively, the conductive fibres may be interposed in the fold back portion e.g. hem of the garment. For an efficient antistatic effect the conductive fibres should not be separated from each other by more than 30cm. The conductive fibres of the invention can be incorporated into suits, trousers, raincoats, overcoats, shirts, skirts and skirt hems, waistcoats and kimonas. Suitable metals for the conductive coating include silver, gold, platinum, copper, brass, nickel, aluminium, tungsten, cobalt, chromium, zinc and tin and suitable binder polymers include synthetic resins such as acrylic, epoxy; phenolic, urethane, melamine, urea, polyester, vinyl resins and combustions of oil-soluble phenolic resins with chloropene polymer, styrene/butadiene copolymer, acrylonitrile/butadiene copolymer and bisphenol/epichlorohydrin epoxy resins.

Abstract: 1,097,590. Frequency modulation; transistor oscillators. ELECTRIC & MUSICAL INDUSTRIES Ltd. March 22, 1965 [March 20, 1964], No. 11902/64. Headings H3R and H3T. A F.M. oscillator of the type comprising a resonant circuit 1, an amplifier 2 regeneratively coupled to the resonant circuit to maintain oscillations, and a circuit to derive from the voltage across the resonant circuit a quadrature current which is introduced into the resonant circuit to vary the frequency of oscillation, is characterized in that the quadrature current is made up of a first component whose amplitude increases with an increase in frequency, and a second component whose amplitude decreases with increase in frequency. The relative magnitudes of the two components are so determined that the deviation of the oscillator frequency is made a more linear function of the modulation input. A first current component of magnitude proportional to jw is derived from capacitor 50 and a second component of magnitude proportional to 1/jw is derived from Miller integrator 3, and the two components are added and fed to the potentiometer 13 in a balanced modulator 4 having a push-pull modulation signal applied to terminals 6, 7. The amplitude modulated output from winding 17 is then fed to the tuned circuit 1 to modulate the frequency of oscillation. The relationship between the two components of current for maximum linearity of the modulation input/oscillator frequency characteristic is derived. The oscillator comprises a pair of emitter coupled transistors 35, 36. The resonant circuit 1 includes a transformer 31, the secondary of which is coupled to the base of transistor 36 to provide sufficient positive feedback to maintain oscillation.
