Title: Selective flocculation and flotation of slimes from sylvinite ores
IPC: B03D1/06
Filed: 1973-04-04
Abstract: 1419554 Froth flotation of sylvinite ores AMERICAN CYANAMID CO 4 April 1973 [7 April 1972] 16198/73 Heading B2H In a method of desliming sylvinite ore a pulp of the ore in saturated brine or a slime fraction thereof obtained from preliminary desliming of the ore is treated with an acrylamide polymer to flocculate the slimes and with a cationic collector for the flocculated slimes and the treated pulp or fraction is then subjected to froth flotation to float off the slimes. The ore may first be crushed and then pulped in saturated brine. The pulped ore is conditioned with 0.005-0.5 pound per ton of the acrylamide polymer and with 0.01-1.0 pound per ton of the cationic collector. A frothing agent, e.g. methyl isobutyl carbinol, is added, air is introduced into the mixture, and the froth containing the slimes is removed by skimming. The skimmed-off froth may be subjected to a cleaner flotation stage, resulting in a froth product containing the slimes and a tailing containing sylvinite removed in the initial treatment. This second tailing is then combined with that from the initial slime flotation and the whole is sent to a conventional sylvinite flotation recovery step. In a modification, the original ore pulp is subjected to preliminary screening or hydrocyclonic separation and the slime fraction obtained therefrom is treated in the same manner as explained for the ore pulp. Examples of suitable acrylamide polymers are given. The cationic collector may be either a condensation product of 1 to 10 mole proportions of ethylene oxide with 1 mole proportion of a nitrogen-containing compound, examples of which are given, or a quaternary ammonium salt (e.g. chloride) having at least one long-chain (C 12 -C 18 ) alkyl or acyl group, examples of which are given.

Title: Character generator
IPC: G09G1/12
Filed: 1970-04-07
Abstract: 1,244,949. Cathode ray tube displays. STROMBERG DATAGRAPHIX Inc. 7 April, 1970 [29 April, 1969], No. 16323/70. Heading H4T. A C.R.T. character display system in which the beam moves successively in a number of straight-line segments derives the three control signals (X, Y and intensity) from a set of three output lines, one set being provided for each character, the lines being selectively threaded through magnetic cores which are energized in turn to generate the segmental signals. As shown the set of three lines 13 corresponding to the required character are selected at 22, and cores 11 through which the lines may be threaded (in either sense) are energized in turn by a series of blocking oscillators in pulse generator 13. The induced signals (positive, negative or zero) control at 27 or 28 the supply of positive or negative current to capacitor 16 or 17, and thus each core when energized controls the X and Y deflection corresponding to one of the segmental elements of a character. The third wire controls, according as it is threaded or not, the blanking or unblanking of the beam. Two types of display are described, one in which line segments are drawn by a moving spot, and the other where the beam is blanked during movement and then brightened to give a dot display, the differences in the apparatus lying mainly in the intensity control circuit 39. The basic repertory of segmental movements is horizontal, vertical and diagonal, corresponding to X only, Y only and X plus Y incremental signals, but additional flexibility is provided by a proportioning circuit 41 which for selected characters controls the addition to or subtraction from the standard valve capacitances 16 or 17, thus altering the direction of the diagonal segments. In the case of " drawn-line " segments signals indicating this proportioning pass to intensity circuit 39 (as do also signals representing the X and Y movements) to allow compensation of beam intensity for linear trace speed. In a modification the X and Y trace speeds may be signalled independently as 0, Œ 1 or Œ 2 units by the use of five lines 13 instead of the two lines shown, the signals on the five lines passing to a decoder controlling the charging circuits. Eighteen cores 11 are described as adequate for character tracing; since many characters require substantially less time may be saved by the use of an additional " stop " wire threaded through the core following that of the last segment. The circuits 14 may be so designed that instead of requiring an input pulse from 13 for each increment of charge to be supplied to their capacitors, the charging is initiated by a first pulse and terminated by a second, thus permitting a more even trace speed. Circuitry for the various units is illustrated and described.

Filed: 1952-06-30
Abstract: 717,085. Change-speed gear. SIEMENSSCHUCKERTWERKE AKT-GES. June 30, 1952 [July 2, 1951; July 24, 1951], No. 16423/52. Class 80 (2) [Also in Groups XXII and XXIII] A rotary drilling machine is provided with at least two fixed predetermined speed ratios between the feed and rotation of the drilling shaft, one for idle travel and at least one for the working operation, the change from idle travel to feed being effected automatically by the feeding resistance. The machine comprises a head 13, Fig. 1, which is fed towards the work by a feed screw 14 rotated by an electric or compressed air motor 17. The drill rod 9 is rotated from the screw 14 through a pinion 22, Fig. 3, mounted by spring keys 22a. The drill head is advanced by a nut 24 held fast with the head by a cone brake 29. When the bit 10 contacts the work, the nut is fed forwardly against the pressure of a spring 27, to engage clutch teeth thereon with a pinion 25. The pinion is continuously rotated by a gear 28 on the drill shaft 12 and imparts a rotation to the nut 24 causing a slower rate of feed. If an obstruction is met during feed, the gear 28 slips on its hub, (not shown). If an obstruction is met during withdrawal, the nut 24 forces the pinion 22 against the casing 18 of the head 13 and locks with it. The nut is then rotating with the screw, and the head, remains stationary. In a modification, the screw 14 is driven at the forward end.

Title: Improvements in or relating to polyurethanes
Inventor: NEWTH FREDERICK HOWARD
IPC: C08G18/18
Filed: 1960-05-12
Abstract: In a process for the production of a polyurethane resin, an organic polyisocyanate or polyisothioisocyanate is reacted under substantially anhydrous conditions with a polyoxyalkylene compound (as defined below) containing a plurality of reactive hydrogen atoms in such amounts that the ratio of total -NCX groups to total hydroxyl groups present is greater than 1:1. The resulting polyurethane contains free NCX groups which are capable of reacting with a compound containing a plurality of active hydrogen atoms to produce a polyurethane plastic. The polyoxyalkylene compound used is an adduct of one or more alkylene oxides and a nucleating agent.  "Alkylene oxide" refers to an organic compound containing an epoxy group that is capable of reacting with the hydrogen atoms in the hydroxy or mercapto groups of the nucleating agent.  Examples are ethylene, propylene and butylene oxides, 1,1-dimethyl ethylene oxide, cyclohexene oxide and styrene oxide.  "Nucleating agent" refers to an organic polyhydroxy or polymercapto compound that has in its molecule an oxygen- or sulphur-containing heterocyclic ring.  Preferred are saturated derivatives of furan, pyran, dioxan, thiophene, dithian and thioxan (for example 2,5- bis (hydroxymethyl)-tetrahydrofuran, 2,6-bis (hydroxymethyl)- tetra-hydroxypyran, 2,5- bis (hydroxymethyl)- p-dioxan) and 2,6- bis (hydroxymethyl)- 3,5-dihydroxy-dithian) and carbohydrate derivatives containing 5- or 6-membered furan or pyran rings, (for example 1,4-anhydro-sorbitol) 1,4:3,6-dianhydro-sorbitol and pentitols).  The polyurethene resins obtained can be converted to a rubber by heating in the presence of a basic catalyst or into a plastic by reaction with a compound containing a plurality of active hydrogen atoms in the presence of a basic catalyst as suitable compounds are specified water, glycols, amines, dicarboxylic acids hydroxy amines and hydroxy- or amino-acids.  A solvent such as benzene, toluene, xylene, gasoline, carbon tetrachloride, ethyl acetate, amyl acetate or solvent naptha and/or a filler may be incorporated in the reaction mixture.  In an example 2,6- bis (hydroxymethyl)- tetrahydropyran and propylene oxide are reacted in the presence of potassium. The product (M.W.1700) is converted to a foam by reaction, in the "one shot process", with toluene diisocyanate, triethylene diamine, stannous octoate, silicone oil and water.
