Title: Means for balancing gimbal assemblies
Inventor: MAZE ROBERT O
IPC: D21J1/00
Filed: 1957-07-03
Abstract: 840,395. Gyroscopic apparatus. MINNEAPOLIS-HONEYWELL REGULATOR CO. July 3, 1957, No. 21044/57. Class 97(3). [Also in Group XXIV] Means for balancing the gimbals of a gyroscope consists of a container mounted on the gimbal and containing an object, such as a ball or a bubble, embedded in a thermoplastic material of substantially different density and means for heating the container to melt the thermoplastic material to allow the object to move. As shown, the rotor casing 34 is journalled in a housing 12, which is filled with a damping liquid which supports the weight of the casing. The rotor casing contains two similar cylindrical containers 70, 72 with their axes at right angles. Container 70 consists of a glass tube 74 surrounded by a heater wire or film 76. The tube is closed by plugs 78, 80 and contains a ball 84 embedded in thermoplastic material such as Wood's metal or a like eutectic mixture, or a thermoplastic resin. The gyroscope motor is driven by a three-phase supply feed into the casing by flexible leads of the kind described in Specification 812,875. The heating element 76, and a similar element surrounding container 72, are connected across two pairs of phase wires, each in series with a condenser. At the normal supply frequency, the reactance of the condensers is high and little current flows in the heating elements. When the rotor casing is to be balanced, an A.C. supply of higher frequency is fed in. At the higher frequency, the reactance of the condensers is less, while the reactance of the motor windings is greater, so that the current flows mainly in the heating circuit. The heat so generated melts the thermoplastic material, and the balls in the containers can be moved by gravity. The rotor casing is oriented so that the required container is vertical, and heating current is applied to the appropriate element for a time estimated empirically from the unbalance. The process is repeated with the second container vertical. The balls may be heavier or lighter than the thermoplastic material, and may be replaced by bubbles.

Title: Telephonic loud speaker
IPC: H04R11/00
Filed: 1929-07-09
Abstract: 315,230. Farrand Inductor Corporation, (Assignees of Farrand, C. L.). July 9, 1928, [Convention date]. Loud-speakers; magnetic instruments. - The armature of a loud-speaker is mounted between, and moves parallel to, a plurality of pole-pieces under the influence of a varying flux which increases in two non-contraposed pole-pieces. The armature 1, Fig. 1, in its normal position overlaps portions of the faces of the pole-pieces, the broken arrows indicating the direction of the magnetic flux, When the coil 2 is energized in one direction, the superposed flux, indicated by the full arrows, Fig. 2, increases the flux between poles N2, S1, and decreases the flux between poles N1, S2, so that the armature moves as shown in Fig. 2. If the coil 2 is energized in the opposite direction, the armature moves in the reverse direction. The armature 1, Fig. 4, is mounted on leaf springs 3, 4, which provide the restoring force, the magnet 9 supplying the initial flux. The coil 2 may be replaced by four coils surrounding the pole-pieces. The armature may be cylindrical, Fig. 10, and may assume varying forms, Figs. 7, 9, not shown. In a modification, Fig. 12, only two pole-pieces are used, and the increase of flux may take place in two pole-pieces on the same side of the armature, the overlap of the pole-pieces by the armature varying with the degree of energization of the coil 37. The maximum amplitude of vibration of the armature is approximately half the width of the pole-pieces and the armature overlaps one half of the pole-pieces in its position of rest.

Title: Method and apparatus for forming and coating glass fibres
IPC: C03C25/16
Filed: 1972-05-05
Abstract: 1359090 Forming glass fibres OWENSCORNING FIBERGLAS CORP 5 May 1972 21190/72 Heading C1M [Also in Division D1] Glass fibres are formed by flowing streams of molten glass from a supply of heat-softened glass and passing the streams through a body of quenching liquid so that the streams attain the correct viscosity and surface tension for attenuation, and attenuating the streams into fibres. The liquid may be contained in an enclosure 36 supplied with liquid from a tank 52 via a pump 62, pipe 63 and manifold 58 at a rate sufficient to maintain the enclosure full of liquid. Means 80 are provided at the base of the enclosure 36 to return liquid from the enclosure to the tank 52 and a trough 50 returns liquid to the tank that has overflowed from the top of the enclosure. The liquid used may be water in which case the streams are actually contacted by steam resulting from the high temperature of the streams. The steam causes turbulence at the surfaces of the glass streams thus forming irregular surface configurations on the quenched fibres. A gas may be passed through the quenching liquid. An inert gas, e.g. nitrogen or carbon dioxide may be maintained between the liquid and the molten glass supply to protect the glass streams from the atmosphere. The quenching liquid can consist of a first liquid such as water on which is floated a lower density second liquid, which second liquid is a glass fibre coating liquid. Alternatively the liquid body, preferably comprising a coating liquid, is in the form of a foam so that the liquid is self-supporting. In either case the coating liquid is preferably an organic solution of a coupling agent such as an organosilane or siloxane. In use the silane or siloxane portion of the molecule attaches itself to the glass fibre leaving the organic portion projecting outwardly, which organic portion may be attached to a resin thus enabling the coating of glass fibre with a resin.

Title: Cyanoethylation of cellulosic materials
IPC: D06M13/348
Filed: 1955-07-25
Abstract: Cellulose is cyanoethylated by treating it with acrylonitrile in the presence of an aqueous solution containing the hydroxide of an alkali metal and an inorganic water-soluble salt of an alkali metal.  The salts which may be used include sodium iodide, potassium iodide, sodium phosphate, sodium thiocyanate, sodium chloride, sodium sulphate and sodium bromide.  Of these the first four are most active in increasing the efficiency of the cyanoethylation.  The proportion of salt used may be varied over wide ranges.  Thus in the case of sodium iodide the percentage used (based on the weight of dilute sodium hydroxide solution used) may range from 20 per cent or less up to 230 per cent; the optimum proportion for a reaction effected at 55 DEG  C. for 45 minutes being 100 grams of sodium iodide per 100 cc. of sodium hydroxide solution.  In four examples, 5 parts of cotton yarn are treated with 270 parts of an aqueous solution of 2 parts of sodium hydroxide and 10, 50, 105 and 170 parts respectively of sodium iodide for thirty minutes, and excess solution is removed.  The 18.6 parts of wet cotton remaining are reacted in each case for 45 minutes at 55 DEG  C. with 80 parts of acrylonitrile, the mixture is neutralized with glacial acetic acid and the cyanoethylated cotton is washed with water and dried.  In a further series of examples cotton is similarly treated but potassium iodide, sodium sulphate, sodium bromide, sodium phosphate and sodium thiocyanate respectively are used in place of sodium iodide.  In each case the sodium hydroxide solution used is saturated with the salt at room temperature.

Title: Production of titanium dioxide pigments
IPC: C01G23/07
Filed: 1966-05-16
Abstract: Rutile TiO2 is prepared by oxidizing TiCl4 in a closed reactor with a gas containing molecular oxygen at a temperature between 900 DEG  and 1700 DEG  C. and a pressure throughout the reaction of at least 20 p.s.i.g.  The product has improved chalk-fading properties.  AlCl3 in an amount equivalent to 0.1-10% by weight of the TiCl4 may be present during the reaction preferably by being introduced into a vaporized TiCl4 stream.  The TiCl4 may be introduced as a vapour into a pressure-resisting corrosion-resistant reaction vessel such as disclosed in Specification 764,082, and as disclosed in that Specification, build-up on the walls may be prevented by passage of cool chlorine or nitrogen into the chamber to maintain the walls at approximately 300 DEG  C.  The cooled chlorine containing gases may be recycled to a chlorination plant.  The pigment suspension produced is rapidly cooled to below 600 DEG  C. to prevent particle size growth, if desired as disclosed in U.S. Patent 2,833,627.  The gas containing molecular oxygen (air, oxygen, oxygen-enriched air) may be humidified by addition of up to 10% by weight of water vapour.  In Example 1 trace amounts of KCl dissolved in water are added to the TiCl4 stream as a metal ion nucleant to aid in particle size as disclosed in Specification 922,671.
