Title: New chromium-complex and cobalt-complex compounds of monoazo-dyestuffs, their manufacture and use
IPC: C09B62/535
Filed: 1962-08-02
Abstract: The invention comprises chromium complex or cobalt complex compounds of ortho-hydroxyortho1 - amino - monoazo - dyestuffs of the azo naphthalene series that contain a sulphonic acid alkyl amide group, the alkyl group of which is substituted by the acid radical of an inorganic oxy acid and that contain as residue of the coupling component that of a naphthylamine bound to the azo group vicinal to the amino group.  The inorganic oxy acid referred to may be for example phosphoric or sulphuric acid. Particularly useful dyes are those of the kind defined having a sulphonic acid amide group of the formula <FORM:0973238/C4-C5/1> in which m and n each represent a whole number not greater than 3. The characteristic sulphonic amide group can be bound to an aromatic nucleus or in the residue of a coupling or diazo component or both.  Especially valuable are the cobalt- and chromium-complexes of ortho-hydroxy-ortho1-amino-monoazo dyes that contain nitro groups and a sulphonamide group of the kind defined e.g. a sulphonic acid-N-a -sulphatoalkylamide group, especially 1 : 2-eobalt complexes of monoazo dyes of the formula <FORM:0973238/C4-C5/2> in which R represents a nitrobenzene residue bound to the azo bridge in ortho-position to the hydroxyl group, R1 represents a naphthylamine residue bound to the azo bridge in a position vicinal to the amino group, preferably a phenyl-amino group, one X represents a -SO2-NH-CH2CH2-OSO3H grouping, or 1 : 2-chromium or cobalt complexes of monoazo dyes of the formula <FORM:0973238/C4-C5/3> in which 2 represents an acylamino group or a hydrogen or a chlorine atom or a methyl or nitro group or an -SO2NH-CH2CH2-OSO3H grouping.  Also mentioned are mixed complexes that contain a nitrophenol-azo-b -naphthylamine dye of the kind defined above and an ortho : ortho1-dihydroxy - dihydroxy - monoazo-dye of the keto methylene series.  The metal complexes are obtained by treating the appropriate metal free dyes with chromium- or cobalt yielding agents in slightly acid to slightly alkaline media.  The monoazo dyes used as starting materials can be obtained by esterification of appropriate dyes containing a sulphonic acid-N-hydroxyalkylamide group with e.g. phosphorus pentoxide, phosphorus oxychloride, concentrated sulphuric acid or chlorosulphonic acid.  The esterification may be carried out in an inert organic solvent, e.g. dimethyl formamide. Additional substituents which may be present include halogen atoms, nitro, nitrile, acylamino, alkyl, alkoxy, sulphone, carboxylic acid, carboxylic ester, sulphonic and other sulphonamide groups.  The dyes may also be made by esterifying appropriate complexes containing cobalt or chromium.  The dyes are suitable for wool, silk, leather, polyamides and polyhydroxylated materials of fibrous structure, e.g. cellulose, especially cotton.  Examples of the preparation of the dyes and their use in dyeing are furnished.

Title: An improved method of uniting the ends of metal band straps
IPC: B65D63/04
Filed: 1937-11-03
Abstract: 489,912. Sealing. GIRVAN, I. W., and SECURITY STEEL STRAPPING, Ltd. Nov. 3, 1937, No. 30066. [Class 146 (ii)] The overlapping ends 10, 11 of metal bands are secured together by cutting in the overlapped ends one or more pairs of individually independent and convergent slits 12, continuing these slits as convergent, divergent, or parallel slits, and displacing the material between the slits out of the plane of the band so that the part of one end of the band at the point 13 where the main convergent slits approach closest to one another projects into or through the other end of the band, with the result that, by relatively moving the ends as by the release of the tension, the displaced part of the upper end engages the sides of the slits and the under surface of the under end. The slits preferably converge at an angle of 5-15‹ and may be straight or may change their direction so as to approach at a steeper angle. In a modification, Figs. 8 and 9, the convergent slits 12 are continued by parallel slits 41, which in turn are continued by divergent slits 42, and the metal between them is displaced partly upwardly and partly downwardly. In a further modification, the slits are separated from their convergent continuations 62, Fig. 11, by semicircular projections or indentations 61, which provide a seal less liable to be separated at right-angles to the plane of the band. Specification 428,166, [Group XVII], is referred to.

Patent GB-831279-A (GB)
Title: Continuous olefin polymerization process
IPC: C08F2/00
Filed: 1956-10-03
Abstract: A continuous process for polymerizing olefins comprises continuously introducing a solution of an olefinic hydrocarbon monomer in a saturated aliphatic hydrocarbon liquid and a catalyst prepared by mixing an organo-metallic compound of Group I, II or III with a compound of a Group IVa, Va, VIa or VIII metal, into a reaction zone, continuously withdrawing a polymer slurry from the reaction zone and adding alcohol thereto in a quenching zone, continuously recovering the polymer and diluent from the slurry and recycling the diluent to the reaction zone. It is preferred after adding alcohol to the slurry in a quenching zone to filter the slurry, to pass the filtrate to a distillation zone thus recovering the major proportion of the alcohol as an azeotrope with the diluent, to recycle the azeotrope to the quenching zone and to redistill the bottoms stream to recover the major proportion of the diluent.  Alternatively, the reaction mixture may be filtered, the recovered polymer washed with alcohol, filtered and the filtrate distilled to recover alcohol as an overhead and the alcohol, recycled to the washing zone. Specified olefins are ethylene, propylene, butylene and amylene, while pentane, hexane, heptane, octane, nonane and decane are specified diluents.  Apparatus for carrying out the process is described.

Title: Improvements in and relating to electric braking systems for direct-current electric motors
IPC: H02P3/10
Filed: 1936-11-07
Abstract: 484,596. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 7, 1936, No. 30381. Convention date, Nov. 7, 1935. [Class 38 (iii)] Dynamo-electric braking.-A motor 1 fed from a generator 2 is brought to rest by reversing the generator field 3, and shunting this field by a circuit comprising a rectifier 10 and the motor armature. This shunt circuit is ineffective on the generator field until the back electromotive force of the motor falls below a fixed value after which the generator field is increasingly short-circuited as the motor comes to rest. To compensate for the resistance of the rectifier 10, a resistance may be included in the circuit of the field 3 and arranged to carry the field current of the motor. Alternatively the generator may have an additional field acting in opposition to the field 3 and connected in series with a resistance 6 through which the field 3 is supplied. In a system described with reference to Fig. 3, not shown, a reversing switch is provided for the generator field 3 additional to the reversing switch effecting the braking connections, so that the motor may be reversed or stopped at will. In the case of a series motor the braking is effected by reversing the armature connections to the supply and connecting a braking resistance in circuit, the rectifier being connected in shunt to the motor armature.

Title: Polysiloxane compositions
Filed: 1958-09-23
Abstract: A composition convertible at room temperature to an elastomer, consists of a liquid diorganosiloxane polymer having terminal -Si(CH3)2OH groups, fillers, an organotin compound in amount of 1-3% by weight of the siloxane and fillers, optionally an aliphatic silicic acid ester, and a silane of the formula: <FORM:0851575/IV(a)/1> wherein each R is an alkyl radical of less than 5 C. atoms and X is CH3 or -OR, in amount of 0,1 to 1% by weight of the siloxane and fillers.  Inert liquid diluents, e.g. dimethylsiloxane oils, are preferably used in mixing the ingredients. In a typical Example (1) a paste (A) of a liquid a -w-dihydroxydimethylpolysiloxane, siliceous chalk and ZnO, is mixed with (B) a mixture of dibutyltin dilaurate and ethyl silicate, and finally with a solution in a dimethylsiloxane oil of monomethyl diisopropylsilane, to yield a paste which at first can be shaped as desired and is converted to the solid elastic state in 4 to 5 minutes after mixing.  Other compositions are given which cure in at least 10 seconds after mixing.  Comparative examples are also given in which (A) and (B) are mixed without the silane or with the hydrolysate of monomethyldichlorosilane or a methylhydrogensiloxane containing terminal monoethoxymonomethyl-silyl groups, but these compositions liberate hydrogen when in contact with water.  Specifications 686,575, 687,759, 743,950 and 764,246 are referred to.

Abstract: 648,735. Lifting-dogs. ROSE BROS. (GAINSBOROUGH), Ltd. Nov. 25, 1948, No. 30584. [Class 78 (iv)] [Also in Group VI] Plastic articles, e.g. a slab 11 of ice cream to be dip-coated, is seized for subsequent manipulation by a pair of spikes 21 when slid down on their supports 38 to penetrate one side only of the slab, the axes of the support being inclined to each other and to the slab. The sliding penetration of each spike is obtained by a collar 42 thereon engaging the slot 43 of a slider 44 actuated by a bell-crank 47-53 when rocked by the striking of a slider abutment 34 by a timed cam actuated lever 31. The actuating linkage comprises the abutment 34, link 57 to arm 56 which rocks the right-hand arm 56, Fig. 2, to the left so that pivot 52 rocks 47 to the left. The left-hand link 47 by means of the intergeared toothed segments 54 is similarly actuated. The spikes are withdrawn after dipping by the reverse action of another abutment, not shown, being moved by another cam striker. The spikes are mounted for carrying and dip-coating at the end of a radial arm 22 pivoted at 23 for raising and lowering (dipping) as it is swept over the undulating rim 26 of a stationary cam 27, by its intermittently rotated support 24. During the seizing of a slab the arm 22 becomes horizontal, resting in a slot 28 in the rim 26, from which it is pushed up, after seizing, by a cam-operated pusher 29. The slab 11 has been initially cut off from a strip 12 in a magazine 13 by a cutter 14. It is received on a raised up platform 16 which then slides down through a transferer 17 which thereby receives the slab and moves with it sideways to position under the spikes. The spikes may consist of a single tine.

Abstract: 916,628. Valve relay circuits. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. Sept. 14, 1959 [Sept. 25, 1958], No. 30624/58. Class 40 (6). [Also in Group XXXVIII] A pulse generator for use in a traffic control system (see Group XXXVIII) comprises two valves V2, a relay F having differentially connected twin windings and two resistance-capacity time constant circuits arranged to control the bias on the two valves respectively. The H.T. is connected through one relay winding to one of the valves, and also in the unoperated state of the relay to the second time constant circuit CA4, R4, R5, R6, but in the operated state to the first time constant circuit CA3, R2, R3, R8 and via the second winding of the relay to the anode of the first valve. Potentiometers VR2, VR3 are adjusted so that the valves are biased to conduct when the respective junctions of R8 and CA3, and R6 and CA4 are connected to the positive supply terminal via contact F1. Closing contacts A3 energizes relay F over its left-hand winding, contacts F1 disconnect CA4 from the positive supply, driving the grid of the righthand valve negative so that it cannot conduct to energize the second winding of the relay. After a time determined by the time constant CA4, R4, R5, R6 the right-hand valve conducts, and the second coil of the relay is energized to cancel the first and the relay releases driving the grid of the left-hand valve beyond cut-off. After a further delay determined by the time constant CA3, R2, R3, R8 the left-hand valve again conducts and the cycle repeats. The repetition rate may be varied by means of contacts D3, D4 which short resistors R3, R5. In the normal condition of the control system, relay A is energized over its left-hand winding, holding the pulse generator inoperative. Operating button PB energizes relay T over lefthand coil and contact T2 operates holding relay A on its right-hand winding and energizing relay B via its left-hand winding. The righthand coil of relay T is also energized in opposition to the first, and the relay releases, releasing A with it and opening contact T1 to drive the grid of valve V1 negative. Relay B remaining held on its left-hand winding over contacts B2 made. After a delay time determined by capacitor CA1 and the tapping between " CN " and the netword POT (4 sec. as shown), the valve conducts and relay T is again energized, initiating a further cycle which results in relay C being left energized over its left-hand winding and valve V1 again cut-off. Due to relay C not being operated, the delay before the valve conducts and T is re-energized if determined by the tapping of CS on the network POT. A further cycle results in relay D being left energized, and after a further delay determined by the tapping of HY, the circuit restores to normal with relay A operated. The circuit is prevented from responding to a subsequent operation of button PB for a time determined by the tapping of " OFF " on network POT.
