Title: Method of Sulphating Materials.
Inventor: HOVLAND HENRY BERT
IPC: C22B1/06
Filed: 1916-05-12
Abstract: 100,488. Hovland, H. B., (Assignee of Frankforter, G. B.). May 15, 1915, [Convention date]. Copper sulphate; sulphates in general. - Metallic ores &c. are sulphatized by treating with an oxidizing-agent without the addition of an acid or ferrous solvent or of a ferric salt in presence of available sulphur under pressure and at a suitable temperature. When the ore &c. does not contain sulphur, sulphurous acid or metallurgicalfurnace fumes and air or oxygen or a solid oxidizing-agent such as manganese dioxide may be used; but when the ore, to which a source of sulphur such as pyrites may be added, contains sufficient sulphur, air or oxygen alone may be used. Heating and cooling devices may be provided in the pressure vessel. The particular application described is the treatment of copper ores, the conditions suitable for a dry process mentioned being a temperature of 500‹ C. and a pressure of 50--100 lb. per sq. in.; but the pressure may at intervals be reduced to or below atmospheric, for instance to facilitate the decomposition of ferric sulphate. The reaction vessel has a double wall, the space between being filled with an inert gas, such as nitrogen, at a pressure greater than that employed inside, for instance 150 lb. per sq. in. It is stated that the ores may be treated by a wet process, oxidized copper ores being treated under sufficient pressure at ordinary temperature. The Specification as open to inspection under Sect. 91 (3) (a) does not exclude the addition of an acid or ferric solvent or a ferric salt and states that catalysts such as nitrogen oxides, metallic chlorides, or water may be employed to facilitate the oxidation nf the sulphurous acid; that an electric arc may be used for the heating and may produce the nitrogen oxides in situ; and that the process may be applied to the sulphonation of bodies such as aromatic hydrocarbons in the manufacture of phenols, naphthols, &c. and the preparation of ether from alcohol. This subjectmatter does not appear in the Specification as accepted.

Abstract: 269,863. Eclipse Textile Devices, Inc., (Assignees of Hasbrouck, L. B.). April 23, 1926, [Convention date]. Clearing-apparatus. - Yarn is cleared or cleaued by means which operates to remove particles and fibrous material from the travelling yarn, to permit them to be loosely re-attached to the yarn, and again to remove them. In the arrangement shown, a wheel 19 is provided with scrapers 31 and pockets 41<a> and is slowly rotated at a speed less than that of the travel of the yarn, and a deflector 23 comprising adjustable blades is mounted beyond a slotted guard plate 22. As the yarn passes through the device the material is detached therefrom by the scrapers, and is successively loosely attached again and detached as the yarn passes over subsequent pockets and scrapers until the yarn leaves the wheel when the matter, which by this actiun and by the rotary movement of the yarn caused by its twist is in the form of a bunch, is finally removed from the yarn by the deflector 23 and falls outside the wheel guard 22. The scrapers 31, shown in detail in Fig. 6, are formed on the rim of the wheel 19 between marginal flanges 40 and are provided with a front surface 33 which intersects a surface 34 parallel to the rim to form a semi-circular scraping edge 35. Yarn guides 20, 21 are mounted on opposite sides of the device to determine the path of the yarn, and an additional guide and a tension device may be mounted in front of the guide 20.

Title: Radio navigators
IPC: G05D1/02
Filed: 1943-05-05
Abstract: 568,236. Automatic control systems for aircraft &c. WARNER, L. A. May 5, 1943, No. 7070. [Class 38 (iv)] Steering.-A navigational system for aircraft, watercraft and like vessels has means for detecting yaw, means for detecting drift and means for changing course at a one to one ratio with respect to the yaw angle to correct for yawing and at a ratio of more than one to one with respect to the drift angle to correct for drift. Directional and non-directional antennµ 10, 14 are associated with a receiver and amplifier 13 to operate a polarized relay 15, whereby a reversible motor 21 is actuated to maintain the antenna 14 in a null reception position. This position is indicated on an azimuth indicator 27 and deviations on a meter 16. A magnetic or gyroscopic compass controls the position of an insulating body 48 associated with electrodes 44 ... 50 constituting an electrolytic Wheatstone bridge. A polarized rolay 33 connected between electrodes 49, 50 operates on unbalance of the bridge due to yaw of the craft or other off-course condition to control a reversible motor 51 operating a rudder 62. The craft is thereby automatically oriented upon a course determined by the setting of a manual control 34a associated with a course-indicating dial 34d and coupled to means for adjusting the electrodes in relation to the compass-controlled member 48. This means is also coupled to the antenna. 10 through a clutch 28 which is engaged by the operation of a relay 17 whenever its orientation is being changed, so that the craft is also automatically oriented upon a radio course, but the operation of the compass-controlled rudder motor is prevented by a switch 30, 31 until the clutch 28 is de-energized. The control of the antenna 10 takes place independently of the rudder control, a relay 36 co-operating with a relay 17 to deenergize the clutch when either control is operative. A gear-box 69 operated by a threeposition lever 70 may be set in mid-position to couple the shafts 32, 32a through a one-to-one ratio gear for normal " housing " on the radio transmitter. To provide drift correction, the lever 70 is set in one extreme position when the radio transmitter lies ahead to couple these shafts in a one-to-two ratio and in the other position when the transmitter lies astern to give a reversed coupling also at a one-to-two ratio. To prevent over-correction, by the rudder, contacts 64, 65 coupled to the rudder operate over resistances 66, 67 so that a clutch coil 55a is energized sufficiently when the rudder is near its mid-position to annul the field of a clutch coil 55b in parallel with the rudder motor and thereby release the rudder. Specifications 388,085, [Group XX], 517,861 and 517,862, [both in Group XL], are referred to.
