Title: The manufacture of new azo-dyestuffs
IPC: C09B35/60
Filed: 1931-05-26
Abstract: Azo dyes; substantive dyes, dyeing with.--Azo dyes are obtained by the process of the parent Specification with a selection of the diazo components such that the nitrogenous groups of at least one of them are in m-position to each other.  The products give greener dyeings than those obtained with the dyestuffs specified in the parent Specification.  The following examples are specified: (1) The nitro groups of the dyestuff, 4-nitraniline --> (acid) 1 : 8 : 4 : 6-aminonaphtholdisulphonic acid (alkaline) \sM 4-nitro-2-amino-anisol, are reduced with sodium sulphide and the diaminodisazo product is tetrazotized and coupled with 2 mols. of m-phenylenediamine; the product gives on cotton black dyeings which become greener and faster to light on after-treatment with formaldehyde and copper salts; a still greener dyeing is obtained when the 4-nitraniline is replaced by 3-nitraniline; the m-phenylenediamine may be replaced by other end components carrying two auxochrome groups in m-position to each other, e.g. resorcinol, m-aminophenol and substitution products thereof, and the 1 : 8 : 4 : 6-aminonaphtholdisulphonic may be replaced by H-acid.  (2) The acetylamino groups of the dyestuff, 2-acetylamino-4-aminobenzoic acid --> (acid) 1 : 8 : 4 : 6-aminonaphtholdisulphonic acid (alkaline) \sM 4-aminoacetanilide, are converted by saponification into amino groups and the diaminodisazo product is tetrazotized and coupled with 1 mol. of m-phenylenediamine and 1 mol. of resorcinol; the product gives on vegetable fibres blackish-green dyeings which become blueish and faster to light on after-treatment with formaldehyde and copper salts; still greener dyeings are obtained when the tetrazo compound is coupled with 2 mols. of resorcinol or 2 mols. of m-aminophenol. (3) The acetylamino groups of the dyestuff, 2-acetylamino-5-aminoanisol --> (acid) 1 : 8 : 4 : 6 - aminonaphtholdisulphonic acid (alkaline) \sM 3-aminoacetanilide, are converted by saponification into amino groups and the diaminodisazo product is tetrazotized and coupled with 1 mol. of m-phenylenediamine and 1 mol. of resorcinol; the product gives on vegetable fibres greenish black dyeings which become faster to washing and to light on after-treatment with formaldehyde and copper salts.  (4) The acetylamino groups of the dyestuff, 2-acetylamino-4-aminoanisol --> (acid) 1 : 8 :4-aminonaphtholsulphonic acid (alkaline) \sM 2-acetylamino-4-aminoanisol, are converted by saponification into amino groups and the diaminodisazo product is tetrazotized and coupled with 2 mols. of resorcinol; the product gives on cotton olive green dyeings which become olive brown and faster to light on aftertreatment with formaldehyde and copper salts.

Patent GB-1586012-A (GB)
Title: Fire detector installation
IPC: G08B17/06
Filed: 1978-04-19
Abstract: The fire detection system has a signalling centre (Z) and fire sensors (Dn, Dn<'>), if appropriate combined in groups, an alarm signalling device (A) being actuated by at least one time delay device (T) in the centre. In this case the time delay which has been put into effect by a fire detector (Dn) is shortened whenever further, less sensitive fire sensors (Dn) respond. The extent to which the delay time is shortened may also depend on the value or the change of an analog output signal of the fire sensors (Dn, Dn<'>). This fire detection system successfully avoids false alarms to a great extent but in a genuine case of fire triggers an alarm signal and initiates the thereby controlled fire fighting measures at as early a time as possible. <IMAGE>

Title: Improvements in or relating to circuit-arrangements comprising a direct-voltage source of comparatively high voltage for the supply of a consumer device absorbing energy in a pulsewise manner
IPC: G01T1/175
Filed: 1950-06-22
Abstract: 677,676. Converting; supply systems; systems for charging condensers. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 22, 1950 [June 25, 1949], No. 15605/50. Classes 38 (ii) and 38 (iv). A condenser 5, for supplying an ionization tube 3 or other intermittent load requiring a relatively high D.C. voltage, is charged from a lower voltage D.C. source 1, each time the load makes a demand on the condenser, through a circuit comprising a transformer 17, 13, 8, a valve 7, a rectifier 9, 19, which is preferably part of the valve, and an ohmic or inductive resistor 4 in the load circuit for controlling the conductivity of the valve. The valve is normally cut-off by a bias battery 11; a starting switch 16, however, allows the bias to be removed so that the valve oscillates (due to the back-coupling produced by transformer windings 13, 17) and generates in winding 8 a high oscillatory voltage, which is rectified at 9, 19 and utilized to charge the condenser. The starting switch is then opened to restore cut-off bias. If now tube 3 conducts, the passage of discharge current of condenser 5 through resistor 4 applies a positive voltage pulse to the grid of the valve through a differentiating circuit 6, 14, whereupon the valve oscillates for a brief period and recharges condenser 5. In the meantime the voltage drops in resistors 2, 4 cause tube 3 to return to its non-conducting state. A meter 21 registers discharges of tube 3. In a modified arrangement the meter shunts the transformer winding 17 in series with a rectifier which is conductive on the opposite half-cycles to those during which rectifier 9, 19 is conductive. The cut-off bias for the valve may be obtained by grid rectification using a non-linear leak, or from the transformer, over a rectifier, instead of from a separate battery. The tube 3 may be continuously acted upon by a weak source of radiation to ensure periodic recharging of the condenser 5 necessary to compensate for leakage.

Title: Improvements in coin or check freed amusement apparatus
IPC: G07F17/38
Filed: 1941-12-06
Abstract: 554,073. Coin-freed amusement apparatus. BRADLEY, L. C. Dec. 6, 1941, No. 15761. [Class 27] Relates to the prize delivery mechanism in coin freed amusement apparatus of the kind in which a ball or projectile is projected round a track in a vertical plane to arrive at winning or losing compartments and to means for preventing fraud by working the delivery means too rapidly. A ball, rendered available by the insertion of a coin, for example by means described in Specification 554,072, is in position for play at 5, Fig. 2, before a hammer 6 which is let go by a shooting trigger 8 to propel the ball along a spiral track 4, from which it ultimately falls past a row of pins 10, Fig. 3, with a central "win" passage 16, or side "lose" passages. The coin comes to rest between the lower end of a lever 23 pivoted at 22 and the extension 24 of the coin shoot 20 and rests on the bent over end 25a of a guided slide 25, the other end of which is pivoted to a crank 27 on a shaft 28 rocked by a "win knob" 29. If a ball arrives in the "win" shoot 16 it rests on the cranked end 48 of the upper arm 42 of a lever fulcrummed at 45 and the lower, arm 43 is pressed against a spring 46 to bring its end out of a notch 37 in an arcuate flange 36 on the crank 27 so allowing the latter to be rocked by the "win knob" 29 and allow the coin to drop over a guide 32 into a delivery opening 34 whence the operator may take it for use again. The slope 41 on the flange 36 rocks the arm 42 of the lever to release the ball from the end 48 whence it falls in front of the hammer 6 for another shot. If the ball falls into a "lose" passage lever 42 is not moved and the arm 43 locks the "win knob." A coin following one resting on the slide 25 is deflected by upper end of the lever 23 over the top of the casing 31, Fig. 5, with a coin receptacle. To prevent fraudulent operation by rapid movement of the "win knob" an inertia arm 49 is provided hinged on it at 50 which lags behind and catches on a bracket 52. In a modification a slide 55, Fig. 14, linked to the crank 27 brings the coin for a winner to the delivery aperture and has the locking notch and ball freeing cam to engage the arm 43 of the ball freeing lever.
