Abstract: 685,244. Ammeters; wattmeters. GENERAL ELECTRIC CO., Ltd., and RUDGE, T. R. Oct. 18, 1951 [Oct. 11, 1950], No.. 24858/50. Class 37. [Also in Group XXXV] In an instrument indicating in dependence on the flux in a closed magnetic path at least the major part of which is formed by a ferro-magnetic core, an opening is provided in the core into which a conductor may be inserted from outside the core, the opening being bridged by a part of the core and means being provided for locating the conductor in the opening relative to the axis of the magnetic path. The ammeter shown comprises a housing 1 enclosing a moving coil meter 3 and the major part of a closed laminated core 14 of nickel-iron alloy. The core is formed with an opening 18 extending inwards for about three-quarters of the width of the core and having a flat edge 21 and a V-shaped edge 22. Two pole-pieces 23, 24 thus project from the casing and are coated with cellulose acetate. A coil 25 is wound on the core and is connected to the meter 3 through a rectifier. A conductor 26 carrying A.C. to be measured is brought into the opening 18 and pressed into the notch 22, thereby locating it so that its centre is at a predetermined distance from the magnetic axis through the core 14. An alternating flux is set up in the core 14 and the meter 3 measures the current in the conductor 26. A range-change switch by which resistances are inserted in series with the meter may be provided in the housing. An elongated electric lamp, such as a fluorescent lamp, may be passed through the central opening 27 in the core 14 so that its operating current may be measured. In a modification the core 14 may be broken at a point opposite the opening 18 to provide a gap in which the moving coil of the meter 3 may be mounted. The invention is applicable to other instruments such as wattmeters.

Title: Manufacture of materials for the cigarette industry
IPC: C08J7/12
Filed: 1931-09-04
Abstract: For use in the cigarette industry, a cellulose ester foil coloured by incorporation therein of a dyestuff, pigment, or metal powder, is treated on one or both sides with a saponifying agent. The superficial saponification enables the foil to be securely united to cigarette paper by means of water-soluble adhesives, and the foil is suitable for making cigarette mouthpieces.  As saponifying agent, an alkali-metal hydroxide or carbonate, or ammonia may be used.  The treatment may be carried out at raised temperature if desired.  In an example, a cellulose ester foil containing bronze powder is wound off from a roll and guided by means of rollers through a bath containing caustic potash.  It is then washed, passed through a drying apparatus and wound up.  The material may be united to a strip of cigarette paper moistened with starch paste.  If only one side of the foil is to be treated, it may be moistened with the alkaline liquid by means of a roller rotating in the liquid.  Specification 157,126, [Class 2 (ii), Cellulose &c.], is referred to.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the application of the process to cellulose ether foils.  This subject-matter does not appear in the Specification as accepted.ALSO:For making cigarette tips, a cellulose ester foil coloured by incorporation of a dyestuff, pigment, or metal powder, is treated on one or both sides with a saponifying-agent to enable the foil to be securely united to cigarette paper by means of water-soluble adhesives.

Title: Improvements in or relating to the manufacture of spun yarn, spun or woven fabrics and other textiles
IPC: A22C13/00
Filed: 1935-09-10
Abstract: Fabrics are made from continuous filament or short fibre yarns, either alone or mixed with other fibres or filaments, which have been made by converting animal hide material by means of swelling agents and if desired mechanical treatment into a highly swollen slippery paste, the latter being extruded under pressures of the order of 100 atmospheres to produce filaments which are dried and thereafter are rendered waterproof, for example, by treatment with tanning agents or pyroligneous acid.  The paste in which the natural fibres of the hide material are maintained, should contain not more than 20 per cent of dry substance preferably 6--12 per cent; and the necessary swelling may be effected in acid or alkaline media, or in an alkaline medium followed by an acid medium, according to the selected conditions at values of pH over 12 and below 4; hydrochloric, formic and acetic are suitable acids, and as alkalies, milk of lime or dilute caustic soda may be employed; the mechanical treatments comprise comminuting, pounding and pressing, and it is advisable to homogenize the fibrous paste by means of a kneading machine or mixer.  The nozzles used for the extrusion are preferably tapered.  For obtaining short fibres, the paste is extruded intermittently as by periodically varying the extrusion pressure, or the continuous filaments are collected on intermittently moving belts so that the filaments are broken at the nozzle into short lengths; alternatively, the continuous filaments may be cut or torn into lengths after drying or tanning. The filaments may be twisted together before or during the sizing operation, or after the sized filaments have been rendered sticky or tacky; and the threads may be treated with softeners, wetting agents, mordants, fats, colours &c.  Specifications 422,990, [Group IX], and 429,039 are referred to.ALSO:Animal hide material is converted into a highly swollen slippery paste still containing the natural fibres of the hide material by treatment with swelling agents and if desired mechanical treatment.
