Title: Improvements in or relating to electro-magnetic separation or concentration of minerals
IPC: B03C1/253
Filed: 1919-03-28
Abstract: 165,822. Mordey, W. M. March 28, 1019. Magnetic separators.-A magnetic separator is fitted with a polyphase alternating-current magnetic system, and the stream of mineral matter to be concentrated passes longitudinally over a long narrow path so that the matter responsive to the rotary field is gradually swept to one side, and the inert matter moves in the opposite lateral direction. The ore &c., usually in the form of pulp, is fed to one end of a series of launders d, Fig. 3, which may be inclined both in the longitudinal and transverse directions, and are arranged above or below long parallel poles e<1> of the magnet e. The passage through the launders may be assisted by agitation or vibration. In order to render the material more responsive to the rotary field, it may be subjected to a preliminary magnetic induction during its passage from the hopper to the launder, or the upper end of the magnet e may be more strongly magnetized than the lower end. The separated responsive matter may be discharged either at the end of the launder or over the sides. The windings g, Fig. 7, of the magnet e may be arranged so that the movement of the responsive matter a' proceeds from the central part of a launder in both directions to the sides, the inert matter a gravitating towards the centre; the magnet and launder in this form are curved slightly at right-angles to their length. The launder may have a cover of magnetic material, or magnets may be used both above and below. In another form, the material flows over the surface of the magnet poles, the spaces between being of the closed slot type. In another form, dry material is carried through the rotary field by an endless belt n, Fig. 10, the surface of which may be flat or curved.

Abstract: 1,057,908. Selective signalling systems. KAMAN AIRCRAFT CORPORATION. Feb. 26, 1964 [Feb. 26, 1963], No. 8047/64. Heading G4H. In a system for controlling the direction and/or speed of the electric motors of an overhead crane, commands are transmitted as pulse trains modulated on a radio-frequency carrier. In one embodiment, a clock source 2, Fig. 1, produces pulses K1-K3 in turn. Each pulse K1 triggers a multivibrator H to produce a pulse which may have either of two durations selected by a switch 10. Other multivibrators B, T are triggered by pulses K2, K3 and produce pulses having durations determined by the positions of switches 11, 12, the pulses produced by multivibrators H, B, T being of different lengths. The information pulses are interlaced and modulated on a r.f. carrier for radiation by antenna 24. The receiver includes a detector 48, Fig. 3, which fires a Schmidt trigger to supply power to the motor circuits when the received signal is above a predetermined level. A multivibrator 62 enables gates G1-G6 in response to the trailing edge of each information pulse. Multivibrators 64 are triggered by the leading edge of each information pulse and have relaxation times corresponding to the six possible command pulse durations so that inverters 66, which include differentiating circuits, open the appropriate gate G1-G6 in response to each command pulse. A relay drive circuit 74 includes an integrating circuit which produces an output response only after ten consecutive command pulses have been applied thereto. The system may be modified, Figs. 6-9 (not shown) to control the speed of the motors. Additional switch and multivibrator units produce a variable duration speed command pulse which is inserted after the corresponding direction command pulse. The receiver includes additional pulse discriminator circuits to select the appropriate speed in accordance with the duration of the speed command pulses.

Title: A method of treating pectin to alter the inherent setting time characteristics thereof
IPC: C08B37/00
Filed: 1935-03-20
Abstract: The setting time of pectin is altered by treating a pectin sol with an acidic reagent, or by treating a pectinous material such as apple pomace or citrus peel with an acidic reagent but without extraction of the pectin.  The treatment must not be so prolonged as to destroy the gel-forming capacity of the pectin.  The reagent may be an organic or inorganic acid, or a gas exerting an acidic action, e.g. chlorine, hydrogen chloride, hydrogen sulphide, sulphur dioxide or trioxide.  The gases may be applied under elevated pressure.  The pH during treatment may lie between 0,1 and 2,5.  The temperature should be below 85 DEG  C.  Treatment of a pectin sol may be effected by leaving extracted pectin to stand in contact with the extracting acid.  Pectinous material such as pomace may be treated with hydrogen chloride gas, alone or dissolved in alcohol or benzol, with acid methyl sulphate alone, or with acid in the presence of an organic liquid, e.g. methyl, ethyl, propyl, butyl or amyl alcohols, ether, diethylene glycol acetone, methyl ethyl ketone, acetyl chloride, ethyl acetate, acid methyl sulphate, aliphatic or aromatic hydrocarbons, alcohols, glycols, ketones, aldehydes, amines or ethers.  Inert gases may also be used as carriers.  Water-soluble carriers may be slightly diluted with water.  On conclusion of the treatment, the material is separated from the treating agent and is washed, if desired in the presence of an alkali or buffering agent. It is found that in the early stages of the treatment, the setting time is extended, but a prolonged treatment causes a decrease in the extended setting time.  Specification 239,635, [Class 121], is referred to.
