IPC: C07D213/89
Filed: 1970-08-04
Abstract: 1323362 Polymyxin derivatives RHONEPOULENC SA 4 Aug 1970 [5 Aug 1969] 37632/70 Headings C2A and C2C Novel cyclic polypeptides having the general Formula I wherein Y-Z represents one of the amino acid chains D-Leu-Thr, D-Phe-Leu, D-Leu- Leu and D-Leu-Ileu ; G is a radical of Formula II: Py-CH 9 -O-CO- in which Py is pyridyl or pyridyl-N-oxide optionally substituted by a methyl group, Dab represents α,γ-diaminobutyric acid, Thr is threonine, Phe is phenylalanine, Leu is leucine and lieu is isoleucine, the amino acids having the L configuration unless otherwise stated, are prepared by hydrolysing a polymyxin of Formula III wherein K is an n-octanoyl, L-6-methyloctanoyl or 6-methylheptanoyl radical, G and Dab are as above, and either (1) Y-Z is D-Leu-Thr and X is D-Dab or D-Serine, or (2) Y-Z is D-Phe- Leu or D-Leu-Leu and X is Dab, or when K is L-6-methyloctanoyl or 6-methylheptanoyl then Y-Z may be D-Leu-Ileu and X is Dab, and when X is Dab it optionally has a group G on the γ-amino group, by an enzyme which is a protease from B. subtilis A.T.C.C. 9524 or an exocellular protease from any appropriate strain of B. subtilis. The preferred enzymes are subtilisin, nagarse, pronase, colistinase or Alcalase (Registered Trade Mark). The compounds of Formula I are useful as intermediates for synthesizing polymyxin analogues having a modified side chain by reacylating the α-amino group on the Dab with an appropriate acid radical, and subsequently removing the protective groups G from the other amino groups e.g. by hydrogenolysis. The starting materials of Formula III are prepared by reacting a polymyxin e.g. colistin, polymyxin B, with a mixed carbonate of Formula V below suitably in an organic solvent such as dimethyl-formamide at 15‹ to 60‹ C. If desired the pyridyl group may be oxidized to the N-oxide before or after the reaction e.g. with p-nitroperbenzoic acid. Compounds having the general Formula V wherein Py is as hereinbefore defined and T is phenyl, substituted phenyl (e.g. p-nitrophenyl; 2,4,5-trichlorophenyl) or a heterocyclic radical (e.g. 8-quinolinyl or 2,5-dioxopyrrolidin-1-yl) are prepared by reacting an alcohol of formula Py-CH 2 -OH with a chloroformate of formula Cl-CO-O-T, and if required oxidizing the pyridyl radical to pyridyl-N-oxide, e.g. with p-nitroperbenzoic acid.

Title: Improved polyolefin reaction products
IPC: C08F8/20
Filed: 1964-09-15
Abstract: A vulcanizable reaction product is obtained by reacting a substantially saturated isomonoolefine polymer of high molecular weight with a brominating agent at an elevated temperature, whereby a brominated reaction product is obtained composed of chains of degraded polymer of which a major proportion possess terminal bromine atoms, and having a viscosity average molecular weight not greater than 20% that of the unbrominated polymer.  The isomonoolefine polymers are prepared from isomonoolefines containing four to eight carbon atoms and having a terminal methylene group and they include homopolymers of isobutylene and copolymers of isobutylene with, for example, styrene.  The brominating agent may be bromine itself or a bromine-releasing compound such as the N-bromo hydantoins and the N-bromo compounds of aliphatic carboxylic acid amides or imides.  The reaction products may be vulcanized with polyfunctional amines, preferably those containing mixed primary and secondary amine groups and aliphatic difunctional primary amines.  In the examples:- (1) a saturated polyisobutylene is treated with dibromodimethyl hydantoin; (2) a solution of a polyisobutylene in carbon tetrachloride is treated with bromine and the product is vulcanized with hexamethylene diamine; (3) a saturated polyisobutylene is heated with powdered N,N1-dibromo-5,5 -dimethyl-hydantoin and the product after compounding with various clays or fillers is vulcanized with triethylene tetramine and (4) an isobutylenestyrene copolymer is treated with bromine and the product vulcanized with tetraethylene pentamine.

Abstract: The invention comprises compounds of formula M(CNS)2Xn wherein M is iron, cobalt, nickel, manganese or copper, n is 2 or 4 and X is a primary phenyl-substituted alkylamine of formula:- <FORM:0931775/IV(a)/1> or <FORM:0931775/IV(a)/2> in which R2 is a straight or branched chain C1-C10 alkyl group, R3 is a hydrogen atom or a straight or branched chain C1-C10 alkyl group and R1 is a hydrogen atom or a straight or branched chain C1-C8 alkyl group.  In the above formula the group (CNS) includes all possible structures of the thiocyanate group. The complexes are prepared by mixing a phenylalkylamine of the above formula with an aqueous solution of the salt MA2 and recovering the complex.  When the total of C atoms in R1 and R3 is less than 4 the reaction is preferably carried out in the presence of a saturated hydrocarbon containing eight or less carbon atoms which is present in a ratio by weight lower than 10:1 with respect to the complex to be formed.  Specified hydrocarbons are pentane, heptane and cyclohexane.  The salt MA2 may be prepared in situ by metathesis using two salts in aqueous solution.  The complexes are used as catalysts, in the preparation of catalysts and as clathrating agents.  In examples: (1) a solution of alpha-phenylethylamine in heptane is added to a mixture of heptane and an aqueous solution of nickel chloride and potassium thiocyanate and the mixture is stirred, the complex wherein n = 4 is filtered off and dried; (2) alpha-phenylnonylamine is added to an aqueous solution of nickel chloride and potassium thiocyanate and the mixture treated as in (1) to give a complex wherein n = 4.  Further examples including the preparation of complexes wherein n = 2 are specified.

Filed: 1962-10-12
Abstract: 982,899. Endless conveyers. AUTOPACK Ltd. Oct. 11, 1963 [Oct. 12, 1962], No. 38670/62. Heading B8A. An endless conveyer comprises a spring- loaded pawl 10 and ratchet 12 for advancing the conveyer in a step-by-step progression, a cam 14 movable into engagement with the pawl 10 to prevent engagement of the pawl 10 with the ratchet wheel 12, article detecting flap 8 operatively connected to article counting means which is prevented from operation outside of a predetermined part of each cycle of the pawl, the counting means being arranged to operate the cam 14 to disengage the drive to the conveyer when a predetermined number of articles has been counted. The conveying surface is formed of an undulating band 6 supported on a series of rods 5 extending between two endless chains 4. The pawl 10 is pivoted on and is reciprocably driven by a carrier 11. Articles delivered to the conveyer at 7 engage and pass the pivoted detecting flap 8 just prior to discharge. Upon a predetermined number of articles being counted by the device coupled to a micro-switch 9 operable by the flap 8, a solenoid 16, Fig. 2 (not shown), is de-energized to cause the cam 14 to engage the end 13 of the pawl 10 whereupon the conveyer is halted. The solenoid is re-energized either automatically or manually when a new batch of articles is required. A further micro-switch 17 in the circuit of the micro-switch 9 renders that circuit operative only when the plunger 18 of the switch 17 is engaged by one of a plurality of projections 19 on the ratchet wheel 12. The projections 19 are positioned to coincide with the position of an article passing the flap 8, and thus engagement of the flap 8 by the high spots of the band 6 does not register with the counting device. The flap 8 and micro-switch 9 are mounted on an adjustable bracket 20. Two parallel-like conveyers may be employed using a common counting device.

The master may be produced, Fig. 1, in a recording medium 1 e.g. a crystal of LiNbO 3  of dimensions 10x10x2 mm. which is supported by means, not shown, capable of making successive stepwise angular movements (e.g. 0À2 degrees). The crystal is positioned to record holograms formed by reference beam 2 and imaging beam 3 which are derived from laser 4 by means of beam splitter 5. The imaging beam 3 is focused as a spot at plane 9 and large numbers of holograms of the spots are recorded by moving the spot successively to an adjacent position on plane 9 and at the same time advancing the crystal 1 through an angular increment. One spot may be recorded in each hologram (for scanning line by line) or two or more spots (for simultaneous scanning of two or more lines). When reading or recording, the surface being scanned may be moved between line scans or kept stationary while the holograms scan the entire area.

Abstract: 1,273,283. Tube supports. COMBUSTION ENG. Inc. 12 Aug., 1970 [13 Aug., 1969], No. 38925/70. Headings F4A and F4S. In a vapour generator, Fig. 1, comprising pressure vessel 10 containing water space 30 through which a large number of U-shaped thinwalled tubes 38 carry heating fluid from header 44 to header 46, a tube support system 70, 72, 74, 86 prevents lateral vibration of the tubes while allowing longitudinal thermal movement. The tubes are spaced apart in closely spaced layers by the support plates 70, 72, 74 which lie parallel to and between the layers in rows perpendicular to the layers of tubes. A baffle structure 28, 26, 24 forms an annular passage 32 down which cold water from inlets 58 flows to enter space 30 at the bottom. The vapour generated in space 30 passes through separators 62 in baffle 28 and driers 64 to outlet 22. The horizontal sections 68 of the tubes 38 are each positioned between a pair of tabs 90<SP>1</SP>, 90<SP>11</SP> on plates 70a, Fig. 7, formed by bending out at right-angles the tabs formed by cutting two rows of E-shaped holes. The length of the tabs is made equal to the tube diameter so that the tubes are constrained by the opposite faces of adjacent plates in a row. The lower imperforate extensions 82a of the plates 70a used in the central row have locating holes 92 through which passes connector rod 94. The lower end of the extensions (82b) of plates (70b) (Fig. 9, not shown) used in the other rows have two vertically extending locating lugs (102) which fit between legs 66 of pipes 38. The upper ends 84 of plates 70 are welded between pairs of retainer plates 104 to the lower arched edge 110 of a structural member 86. Members 86 have upper flanges 106 to increase rigidity and are slidably mounted at 112 on baffle 24. The vertical legs 66 of tubes 38 are positioned by tabs 90, 90b of plates 72, Fig. 14, in a manner similar to that above except that the plates 72 extend horizontally and are fixed at their outer ends to baffle 24 and at their inner ends to a connecting rod 128 via plates (127). A rectangular recess 160 in the outer end of each plate 72 fits over annular support 124 plug welded to baffle 24. Adjacent plates are bolted to opposite legs of U-shaped pieces 138 acting to constrain the outer tubes 38 in some cases. In region 40 the legs 66 of the tubes are positioned between tabs 154 formed along both edges of plates 74, Fig. 21, by making oblique cuts into the plate edges and bending out the triangular tabs so formed. The outer ends of plates 74 are rigidly mounted on baffle 24 (as plates 72) except for the uppermost rows which are slidably mounted. The inner ends of the plates 74 in the uppermost rows are fixed to rod 94 but the other plates 74 are merely rested on top of the uppermost of plates 72.
