IPC: C09B62/503
Filed: 1977-04-15
Abstract: Preparation of water-soluble, green phthalocyanine-azo dyes of the formula (I) <IMAGE>  and salts thereof by diazotising an amine of the formula (II) <IMAGE> in which the amino group is bonded to an aromatic carbon atom of the radical ar, and coupling in an aqueous medium at a pH of 3 - 8 with a succinic acid derivative of the formula <IMAGE> and converting the resulting hydrazone of the formula (III) <IMAGE> with alkali into a pyrazolone, and coupling this pyrazolone with the diazonium compound of an appropriate amine. The meanings of the symbols A, B, X, k, l, m, n, p, Pc, ar, R1, R2, R3, R4, and R'4 are defined in Claim 1. The dyes obtained can have fibre-reactive properties and are highly useful for dyeing and printing cellulose and natural and synthetic polyamide materials, have high degrees of fixation and produce yellowish to bluish green dyeings and prints of high brilliance and colour strength combined with very good fastness properties.

Title: Improvements in breathing apparatus
IPC: A62B7/10
Filed: 1929-05-21
Abstract: 333,647. Davis, R. H. May 21, 1929. Respirators. - In a breathing- apparatus, a flexible gas-tight bag a is open to a canister h containing a substance which reacts only to absorb carbon dioxide, for example soda lime, or caustic soda, or a mixture of the two, connected to a mouthpiece m, so that the breath of the user will pass through the container to the bag. In the bag, one or more capsules b containing compressed air, oxygen or a mixture thereof are attached to a fitting e by means of a closed screwed tube d so that when external pressure is applied to the capsule, the tube will be ruptured, thereby allowing the compressed gas to escape into the bag. An independent source of respiratory gas may be obtained from a cylinder q, the gas being allowed to escape through the cross passage u into the bag. The bag is also fitted with a connection piece x containing a non-return valve y, so that a supply of respiratory gas independent of the capsules or cylinder may be obtained. This connection need not necessarily be through the canister. A non-return valve z for escape of excess gas is in the form of a flattened rubber tube, and may be provided with a tap or clip for closing it in a poisonous atmosphere. A non-flexible valve may alternatively be used. The canister h containing the carbon dioxide absorbent between layers of iron wire gauze i, i<1> is attached by means of a hollow fitting n to the upper wall a<2> of the breathing bag. This upper wall is made of elastic material, for example, rubber, so that by stretching the opening a<o>, the canister may be placed in, or removed from the bag. The canister may also be arranged exterior to the bag with its lower end opening thereto. Specification 336,674 is referred to.

[Also in Division F1] The angular position of a shaft 3,which is rotatable in bearing bores 2 in a casing 1, is determined by a plunger 14 bearing against an annular cam 15 on shaft 3, the arrangement being such that when a source of pressure fluid is applied at coupling 18, a port 16 is connected to drain and a pressure gauge 23 is connected to an outlet 21, since the force exerted by spring 13 on the ball 12 of a relief valve,between coupling 18 and port 16, depends on the position of the slidable plunger 14,the reading on gauge 23 is related to the angular position of the shaft 3. The indicator as shown is applied to a fluid-pressure operated actuator for producing rotary motion as described in Specification 965,393. In a modification the indicator is used to show linear movements of a pressure operated ram by locating the relief valve in close proximity to the ram with the plunger thereof in contact with an axially extending cam on the ram.

[Also in Group XL (b)] The amplitude of the H.F. components of the luminance signal in a colour television receiver is accentuated by translating the signals over two paths, one of which includes a delay device 30 and the other of which introduces either zero delay, represented by resistor 33 (or includes a time delay different from that introduced by device 30) the input signal to the latter path being reversed in phase with respect to the input to the other path and the outputs of the two paths combined across resistor 41 to produce a resultant signal in which, due to the differences in time delay and the phase reversal introduced by valve 35, the high-frequency components are combined additively and the low-frequency components subtractively. The delay device 30 may be that normally employed in colour television receivers to equalize the transmission times of the luminance and chrominance channels and the arrangement according to the invention may also be employed in the " I " chrominance channel (i.e. between the " I synchronous detector 20 and the signal combining system 18) both to boost the H.F. components thereof and also to provide delay equalization between the " I " and " Q " channels.
