Title: Manufacture of new diazo preparations
IPC: F16N11/02
Filed: 1937-03-09
Abstract: Diazo preparations are manufactured by precipitating a diazonium salt derived from an aryl ether of 4-chloro-2-aminophenol with a manganous salt derived from a hydrogen halide or with another manganous salt in the presence of halogen ions.  The products may be mixed with auxiliary substances, e.g. aluminium sulphate, chlorobenzenedisulphonic acid, naphthalenetrisulphonic acid or Glauber's salt.  Examples describe the precipitation, by means of manganous chloride and common salt, of the diazo compounds of: (1) 4-chloro-2-amino-1 : 1<1> - diphenyl ether; (2) 4 : 4<1>-dichloro-2-amino-1 : 1<1>-diphenyl ether; (3) 4 : 2<1>-dichloro-2-amino-1 : 1<1>-diphenyl ether.  Samples have been furnished under Sect. 2 (5) of diazo preparations obtained by the use of manganous sulphate in place of manganous chloride in the processes of the examples above.  The Specification as open to inspection under Sect. 91 comprises also the use of other diazo salts, e.g. those from other aminodiphenyl ethers, a - and b -naphthylamine, 1-amino-4-benzoylamino-2 : 5-diethoxy- or -dimethoxybenzene, 4-amino-1 : 1<1>-azobenzene and its 2<1> : 3-dimethyl- and 3-methoxy-derivatives, and 1-aminonaphthalene-4-(2<1>-methoxy or ethoxy)-azobenzene.

In a screen-stencilling apparatus in which a cylinder 2 is rolled over an assembly comprising superimposed stencil 3, material 4 and back plate 5, electrostatically charged powdered ink particles 6 are passed from the cylinder through the stencil to the material by an electrostatic field set up between a corona discharge electrode 1 and the plate 5 which is in the form of an electrode. The imaged material is fixed by heat or solvent. In a modification of this apparatus the cylinder 2 is replaced by a cylinder having a conductive layer incorporated beneath the powder carrying surface layer. The conductive layer forms a third electrode and is connected to the electrical source such that an electrostatic field may be established between that part of the cylinder adjacent the stencil at any one time and the electrode 5. In another apparatus the material 4 is in the form of a continuously moving web and the stencil comprises an endless band moving around a space in which is housed the cylinder 2, powder-feed means and the electrode 1. In yet a fourth apparatus the third apparatus is modified by replacing the cylinder 2 by a roller forming one of three rollers around which an endless band is moved. Powdered ink is fed to this band and carried thereon around the said one roller which is connected to the electrical source thereby forming the third electrode.

Title: Improvements in or relating to signal transmitting systems more particularly for musical or like programmes
IPC: H04H20/81
Filed: 1931-03-06
Abstract: 366,317. Automatic exchange systems. GENERAL ELECTRIC CO., Ltd. and COLLYER, J. E., of General Electric Co., Stoke, Coventry. March 6, 1931, No. 7000. [Class 40 (iv).] A subscriber's line may be connected for the reception of any one of a number of wireless or like programmes by means of a rotary switch PS which is controlled by dialling when a key CO is operated. The loud-speaker LS is then connected to the line through a transformer LT, the centre point of which is earthed over the off-normal springs ON and impulse springs D of the dial, while the bell B is disconnected. Relay A energizes over wire L2, the usual line relay L being inoperative, and connects up sluggish relay B, and impulses are repeated to step the switch PS, sluggish relay C being energized during the train to maintain the impulsing circuit and to open the circuit over wire L1. When the dial returns to normal, relays A, B fall back in turn, closing a momentary energizing circuit over wiper ps3 for switching relay SS of the type described in Specification 354,847, [Group XXXVII], . which maintains its armature in either of two positions without the continuous application of energizing current. The connection includes condensers CC1, CC2, while chokes CH1, CH2 are connected in series with relay A. When the key CO is restored to turn off the programme, a momentary connection is made at springs co4 to send an impulse which is repeated by relay A to the releasing winding of relay SS. The switch PS then restores to normal. If the switch PS is set to an unused position, it restores immediately on the relapse of relays B, C. If the line is called while a programme is being received, relay H energizes over the test wire P and superimposes a ringing tone on the programme. The line may, however, be arranged to test busy by connecting earth to contact ss9 in place of relay H. The key CO may be restored automatically by the switchhook when the receiver is lifted. Relay A has opposed windings so that it does not energize over the loop when an ordinary call is made. The subscriber may be provided with extension loud-speakers LA, LB connected across the transformer LT by means of keys and each having a dial.

Title: Improvements in the preparation of aromatic sulphamic acids
Inventor: SUREAU ROBERT FREDERIC MICHEL
Filed: 1955-03-11
Abstract: Aryl sulphamic acids are prepared by the action on a primary or secondary aromatic amine of a sulphonating agent consisting of the addition product of sulphuric anhydride, chlorsulphonic acid, an alkyl chlorosulphonate or pyrosulphuryl chloride and a pyridine base having at least one methyl group in the ortho position to the nitrogen atom or a mixture of such bases or a mixture of tertiary bases, the major proportion of which consists of one or more of the above-mentioned pyridine bases.  Pyridine bases specified are 2-methyl- or 2 : 6-dimethyl-pyridine and mixtures thereof.  The aromatic amines may be nuclearly substituted by halogen atoms or by alkyl, alkoxy, nitro, sulphonamido or carboxylic amide groups and those mentioned are 2 : 4- and 2 : 6-dinitro-aniline and 4-nitro-diphenyl.  The effective sulphonating agent is stated to be the anhydrosulphonate of the pyridine base.  The sulphonation may be conducted by adding the amine to the sulphonating reagent previously prepared by adding the sulphur-containing compound to the pyridine base.  When the nitroarylamines mentioned are sulphonated the reaction may be conducted at slightly elevated temperatures, and the product is isolated by pouring the reaction mixture into aqueous sodium carbonate, steam distilling off the pyridine base, filtering off any unreacted amine and separating the sodium salt of the sulphamic acid by cooling or salting-out the filtrate.  Examples are given.

Projectiles.-A projectile intended to be dropped from aircraft is provided at the moment of launching a a parachute which opens out and checks the horizontal speed of the projectile, and is then released from the projectile, allowing the latter to fall substantially vertically. As shown, the parachute 7 is arranged in a casing 10 at the rear end of the projectile 1, and is connected to an eye-bolt 5 on the projectile by a line 6 which is tied round a glass tube 11 containing a corrosive acid. When the projectile is dropped, the parachute opens out and extends the line 6, which jerks and breaks the glass tube 11, spilling the acid into a recess 4 around the eyebolt 5. After a short time the line 6 is decomposed by the acid and breaks off, leaving the projectile free from the parachute.

Title: Aircraft ground proximity warning systems

Filed: 1976-02-24
Abstract: 1500636 Ground proximity warning systems SUNDSTRAND DATA CONTROL Inc 24 Feb 1976 [2 April 1975] 07219/76 Heading B7W A ground proximity warning system forces the crew to increase the altitude of the aircraft by a predetermined amount (200 ft.) every time a terrain closure warning is generated. An initial warning received along line 24 sets flip-flop 26 to produce and maintain a continuous closure warning via OR gate 32 and an AND gate 34. To terminate the warning the aircraft must climb at a rate (hÀ B ) of at least 300 ft./min., which causes a signal to be fed along line 36 to AND gate 34 to inhibit the warning signal. When the aircraft has climbed at least 200 feet, measured by integrating at 48 the rate of climb signal hÀ B , the flip-flop is reset. Should the aircraft reduce its climbing rate to below 300 ft./min. before climbing 200 ft. the warning signal is reactivated. An OR gate 61 may be provided to maintain a warning signal if the aircraft continues to approach the terrain even though it is still climbing above the predetermined rate of 300 ft./min.
