Title: Process for the preparation of derivatives of aliphatic sulphonic acids or their salts
IPC: C07D295/14
Filed: 1954-08-05
Abstract: Derivatives of aliphatic sulphonic acids or their salts are obtained by reacting together a compound which contains a reactive hydrogen atom or a reactive replaceable metal atom or an atom convertible to a higher state of valency and which can be alkylated and a cyclic anhydride of an organic sulphonic acid (a sultone), if necessary in the presence of acid-neutralizing means, the reaction being carried out in the presence of water or an aqueous organic solvent.  As sultones there may be used 1,3-propane sultone, 1,4-butanesultone, isobutane sultone, tolylsultone, and 1,8-naphthsultone.  The other reactant may comprise hydroxy, carboxy, amino, imino, amido, imide or mercapto compounds of inorganic, aliphatic, cycloaliphatic, aromatic or heterocyclic nature or salts thereof, thiol-acids, dithio-acids, xanthogenic acids, dithiocarbamic acids, trithiocarbamic acids, trithiocarbonic acids and sulphinic acids, tetiary amines, thio-ethers and phosphines.  Examples disclose the preparation of the sodium salt of 2,4,6-trichlorophenoxypropaneo -sulphonic acid, sodium phenylthiopropane-o -sulphonate, the disodium salt of thiocarbonylbis-thiopropane-o -sulphonic acid, sodium N,N-diethylthiocarbamic acid - propyl - ester - o  - sulphonate, the sulphobetaine of isothiourea-S-propane-o -sulphonic acid, the sulphobetaine of isothiourea - S - butane - o  - sulphonic acid, sodium mercaptobenzthiazole-S-propane-o -sulphonate, the betaine of pyridine-N-propane-o -sulphonic acid, 3-chloropropane-1-sulphonic acid, the sodium salt of piperazine-N,n1-bisdithiocarbonic acid - n - propylester - o  - sulphonic acid, and the sodium salt of N,N-diethanoldithiocarbamic acid n-propyl ester sulphonic acid.

Abstract: 1,196,095. Bearing angle computation. RACAL BCC Ltd. 23 Oct., 1968 [14 May, 1968], No. 22759/68. Heading G4G. [Also in Division H4] Signals (e.g. from a radio direction-finder) proportional to sin Q and cos Q, respectively, where Q represents an angle (e.g. a radio bearing) are fed via respective channels to a comparator 7 which measures the ratio of its inputs and the magnitude of one signal is modified by a factor such as to make that ratio unity, whereby the factor is proportional to tan Q or cot Q. Each amplifier 3, 4 is provided with a feedback network and the overall gain of an amplifier is controlled by varying the conductance of the respective element 8, 10. The comparator determines which channel contains the smaller signal and causes the gain in that channel to be increased. The conductance G for amplifier 3 is controlled when sin Q < cos Q and G = tan Q; when sin Q > cos Q the conductance G for amplifier 4 is controlled and G= cot Q. Angle Q is extracted from tan Q or cot Q by providing a generator 12 of a parameter # which feeds a function generator 13, # gradually increasing from zero until the appropriate feedback element conductance equalizes the outputs of detectors 5, 6; when this occurs a further increase in # is inhibited. Parameter # may be a linear ramp voltage but to increase accuracy # may be expressed digitally as binary signals on a number of parallel lines, the function generator 13 being a diode matrix and the feedback elements being resistors controlled by a combination of binary switches, Figs. 2, 3 (neither shown); by a modification the bearing Q may be expressed within the range 0 to 360 degrees, Fig. 4 (not shown).

Title: Improved process and apparatus for the pneumatic sorting of fragmentary materials
IPC: B07B4/02
Filed: 1938-08-03
Abstract: 511,228. Pneumatic separating. LELOGEAIS, P., and SEILLIER, V. Aug. 3, 1938, No. 22995. Convention date, Aug. 5, 1937. [Class 117] In the separation of fragmentary materials, batches of the materials are fed through an air stream into a zone where the lighter and heavier constituents are separated, and the air speeds are suddenly adjusted so as to carry off the lighter constituents or allow the heavier constituents to drop. As shown in Fig. 1, a casing 1 has an inlet 2 for air supplied under pressure and an opening controlled by a valve 6. A vertical conduit 3 with an oblique conduit 4 with a control shutter 5 communicates with the top of the casing. The material is fed into the conduit 4 while the valve 6 is closed and the materials separate into an upper lighter layer at the top of the space 8 and a lower heavier layer. Closing of the shutter 5 and opening of the valve 6 causes variation of the air speeds so that the heavier constituents fall into the casing 1 and the lighter constituents are carried along the conduit 9. The operation of the shutter 5 and valve 6 may be effected automatically and periodically, and the air streams may be produced by suction. Fig. 2 shows a modification comprising two air conduits 11, 13, meeting in a vertical conduit 15 rising from a casing 16. The material is fed from a hopper 10 into the conduit 11 and is carried along to the junction with the vertical conduit where the reduced speed of the air allows the heavier constituents to fall into the casing 16 while the lighter constituents are sustained. Closing of a valve 14 in the wall of the conduit 11 increases the air speed to such an extent as to carry off the lighter constituents. A further modification is shown in Fig. 3 which comprises a casing 18 connected at the top to two conduits 23, 24, and at the bottom to an air supply. A second air conduit 19 to which the material is fed from a hopper 20, is connected alternatively to the conduits 23, 24, by two shutters 21. The lighter constituents are carried away through the conduit 23 or 24 in connection with the conduit 19, and when the shutters are moved to put this conduit in connection with the casing 18, the heavier materials fall into it. For multistage stage separation, the plant may comprise a number of apparatus in series, or parallel or series-parallel.

Abstract: 436,032. Separating solid materials. HORSFIELD, W. R., 14, Regent Street, London. Aug. 10, 1934, No. 23202. [Class 117] Vegetable articles such as dried peas, beans, seeds, &c. subject to defects which appear as small surface cavities are sorted by causing the articles to move relatively to spaced needlelike projections formed and disposed to impale the defective articles and separate them by transport from the others. Preferably, the articles are presented to the projections in a thin layer on a supporting surface. In one form of apparatus for carrying the invention into effect, a large number of needle points 13 are mounted on bosses 14 on the inside of a rotating drum and are disposed to point in the direction of rotation of the drum. The articles are fed in a single layer from a hopper 7 by means of a stirring device 12, a rotary feed wheel 9 and shoot 11. The bosses 14 are triangular in shape and arranged in break-joint order so that the articles are directed from the point of one to that of another. The unperforated articles pass through the drum to a collecting shoot 25, while those exhibiting perforations are impaled on the points 13 and are carried upwards in the rotation of the drum until they are swept off into a stationary collecting trough and conveyer 16 by a rotary brush 18. In an alternative construction the points may be mounted on an inclined conveyer band or on the outside of a drum.
