Title: Water-soluble organic dyestuffs and optical brighteners and their manufacture and use
IPC: C09B33/153
Filed: 1974-09-12
Abstract: 1477396 Transiently water-soluble organic dyestuffs CIBA-GEIGY AG 12 Sept 1974 [27 Sept 1973] 39846/74 Heading C4P Novel water-soluble dyestuffs and optical brighteners contain at least one hydrophilic ether group derived from polyols, bound via grouping whereby the N atom belongs to an acid amide grouping of the dyestuff or o.b. molecule, and the oxygen atom is bound to the hydrophilic ether radical. This grouping can be split off to give a water-insoluble material absorbed on to the fibre material. Typical structures which may be produced are based on monoazo, disazo, anthraquinone, phthalocyanine and other dyestuffs and optical brighteners. These compounds which must contain at least one methylol group bound to an amide nitrogen are reacted with an optionally substituted alkylene oxide in the presence of a transition metal alcoholate (e.g. of Zr<SP>IV</SP>, Nb<SP>V</SP>, Ta<SP>V</SP> or W<SP>VI</SP>) and optionally in the presence of an alkali metal hydroxide or alcoholate. The thus obtained dyes or optical brighteners may be used with a wide variety of lacquers, oils, waxes, paper, leather and furs; and preferably with organic fibres such as cotton, jute, silk, wool, cellulose esters, polyamides, polyesters, polyurethanes or polyolefines.

Abstract: 886,025. Ultrasonic wave couplings. KRAUTKRAMER, J., and KRAUTKRAMER, H. Dec. 11, 1958, No. 40053/58. Drawings to Specification. Class 40 (4). [Also in Groups XL (b) and XL (c)] In pulsed ultrasonic flaw measuring apparatus (see Group XL (c)) a piezo-electric crystal is coupled to the test piece by a foil of polytetrafluoroethylene, and the effects of interference fields from the edges of the crystal plate are reduced by arranging that the radiation from the plate accords with a Gaussian distribution, Fig. 4 (not shown) ; this may be obtained by (1) absorbing layers at the edges of the plate, (2) applying greater damping at the rear of the plate edges than in the centre, (3) hollow grinding of the plate, (4) dividing the exciting electrode into rings and diminishing the applied voltage towards the plate edges, e.g. by an electrode of surface resistance varying with radius, or (5) increasing the separation between electrode and plate towards the edges.

Abstract: A compound of the formula <FORM:1043512/C2/1> where M is a cation having a valence of 1, 2 or 3; X is a group which is capable of being bonded to a carbon in an aromatic ring; Z is an organic sulphide; n is 1 or 2; y is 0 or an integer up to (10-n); and b is 1 when n equals 2 and is equal to the valence of M when n equals 1, is made by reacting, in a mixture of a saturated aliphatic carboxylic acid which contains up to 6 carbon atoms and which is liquid under the reaction conditions employed, and a strong acid having a pka of 2 or less, an organic sulphoxide Z-O, with a decahydrodecaborate compound of the formula Ma1[B10H10- yXy]b1, where M, X, Z and y have the above meanings and a1 and b1 are integers determined by the valence of M and [B10H10- yXy].  The sulphoxide may be prepared in situ by oxidation of the corresponding sulphide with an oxidizing agent. The decahydrodecaborate compounds are made by reacting an organic sulphide USU1, where U and U1 are hydrocarbon groups, preferably alkyl, with decaborane B10H14 at a temperature between 0 DEG  and 150 DEG  C. to form a decaborane (12)/organic sulphide adduct which is reacted with liquid ammonia or an amine at a temperature between - 50 DEG  and 0 DEG  C. for about 1 hour to form the salt M2B10H10. Substituted decahydrodecaborates are made by reacting (NH4)2B10H10 with the appropriate reagents containing the desired group X using conditions conventionally employed for introducing X into benzene. Temperatures between - 20 DEG  and 200 DEG  C. are suitable, and pressures and catalysts may be used.  The X groups in the products can be modified by conventional methods and other desired cations M can be introduced by simple metathetic reactions.

Title: Vehicle automatic emergency signalling device

Filed: 1974-09-19
Abstract: 1463524 Inertia switches C BOUCHARD and R BOUCHARD 19 Sept 1974 [4 Oct 1973] 40833/74 Heading H1N [Also in Division G4] A vehicle automatic emergency signalling system includes an inertial switch which makes a circuit to flashing lights on the vehicle when deceleration is above a predetermined magnitude and an arrangement to ensure that the switch opening, following closure, is delayed. The time delay mechanism may be clockwork or hydraulic. General arrangement. Fig. 1.-Box 1 contains the switch and time delay mechanism and is preferably mounted in the engine compartment. A set of flashing lights 9 are mounted on each side of the rear of the vehicle and above the conventional stop lights. Tell-tales on the dashboard are added. A manual control system 10 is mounted so as to be readily accessible to the driver; lever 17 is movable to positions for travel on a slippery surface, Fig. 2 (not shown), or a non-slippery surface, Fig. 3 (not shown), and for emergency signalling independently of sudden vehicle deceleration, Fig. 5 (not shown). Switch details. Fig. 4.-Fig. 4 shows a weight 25 in its forward limit position caused by a sudden stop. (Its back limit position is against an adjustable stop 53 and retained by a spring 35.) Switch contacts 45, 46 are thereby made and the time delay in the movement of weight 25 to its back position is ensured by a clockwork mechanism 67 which incorporates a ratchet 68 and pawl 71. A typical time delay is about 1 minute. In a collision a latch 56 engages flange 30 of weight support lever 27 thereby overriding the time delay mechanism so as to cause continuous flashing of the indicator lights unless lever 17, Fig. 1, is moved to a further position causing unlatching and bringing into operation of the time delay mechanism. The movement of weight 25 is substantially the same on downhill and uphill sudden deceleration. In an alternative time delay mechanism a dash-pot arrangement is utilized, Figs. 6 to 9 (none shown).

Abstract: 1401308 Fuel elements UNITED KINGDOM ATOMIC ENERGY AUTHORITY 13 Aug 1973 [12 Sept 1972] 42378/72 Heading G6C A fuel assembly comprises a bundle 1 of finned fuel elements 2 within a casing 3 and collapsible fillers 5 disposed in the gap between the bundle 1 and the casing 3, the fillers 5 being longitudinally convoluted generally to follow the transverse contour of the bundle. Each filler 5 comprises two spaced membranes forming an envelope which is flattened at each end over transition lengths to enable the ends to make contact with the casing 3 (shown in broken line in Fig. 2) and thereby prevent longitudinal flow of coolant between the filler 5 and the casing 3. The membrane adjacent the casing 3 is slit to form tongues 6 which are deformed outwardly to form leaf springs for reacting on the casing to urge the envelope towards the bundle. The collapsible fillers serve to restrict the coolant flow path between the casing and the bundle thereby reducing over-cooling of the outer fuel elements but are capable of progressive collapse to accommodate adverse tolerances of the casing and the bundle on assembly and differential growth during irradiation in a reactor. The casing 3, fuel element sheaths, wire wrappings 4 on the sheaths and the fillers 5 are all of alloy steel, and the fuel assembly is for use in a sodiumcooled, fast reactor.
