Filed: 1925-05-27
Abstract: 257,333. Dawson, Sir A. T., and Buckham, Sir G. T. May 27, 1925. Projectile fuzes.-Relates to direct-action percussion fuzes in which the detonator is carried in a movable holder and is normally out of line with the striker and the flash passage. According to the invention, the detonator is moved to the armed position during flight by means of a spring which may be helped by centrifugal force, instead of by centrifugal force solely as heretofore. In the form shown in Figs. 2 and 3, the detonator bx is arranged in a holder B mounted to rotate transversely in the fuze body A, but normally locked by bolts C. During flight, the bolts C move out by centrifugal force, and the holder B, thus released, is rotated by a spring B<1> until stopped by a stud a<0> ; the detonator bx is then opposite the firing pin d of the direct-action striker D, and in line with the flash passage a. The safety parts of the fuze are confined by a screwed sleeve A<1>; and the fuze is protected during transit by a detachable cover Ax. In a modification, the detonator holder is slidable transversely, instead of rotatable.

Title: Manufacture of disazo- and polyazo-dyestuffs
IPC: C09B35/00
Filed: 1943-08-26
Abstract: Dis- or poly-azo dyes are made by coupling components with tetrazotised 3-oxybenzidine and, if desired, performing a further coupling or linking reaction or reactions, a 3-alkyl-pyrazolone being used as at least one of the components, advantageously as the second in order that it may couple with the diazo group which is in o-position to the hydroxy group.  The coupling components may be benzene or naphthalene derivatives or may contain a heterocyclic system or a carbon atom capable of coupling in an open chain, the following being specified: phenols, salicylic acid, resorcinol, naphthols, naphthol mono- or di-sulphonic acids, aminonaphthols and sulphonic acids thereof, and 3-alkylpyrazolones substituted or not in the 1-position by an aryl (e.g. phenyl) nucleus which may contain further substituents, e.g. sulphonamido, nitro, amino or salicylic acid groups.  Especially valuable dyes are made when at least one of the components contains a salicylic acid grouping, which may be present in the pyrazolone, e.g. when 1-(31-carboxy-41-oxyphenyl)-3-methyl-5-pyrazolone is used.  To make tris- or poly-azo dyes components are used which (a) contain an amino group capable of further diazotisation or a group convertible thereto, (b) are capable of coupling more than once, or (c) are suitable for bringing about other linking reactions, e.g. the formation of ureas or the linking of two nitro groups by reduction, 1-(31-aminophenyl)-3-methyl-5-pyrazolone, 2-amino-5-oxynaphthalene-7-sulphonic acid, resorcinol and 5 : 51-dioxy-2 : 21-dinaphthylamine-7 : 71-disulphonic acid being specified.  The dyes are suitable for dyeing or printing animal fibres, e.g. wool, silk and leather, and cellulosic fibres, e.g. cotton, linen, artificial silk and staple fibre of regenerated cellulose.  The dyes may be reacted with agents yielding metal, especially copper, in substance, in the dyebath or on the fibre.  In the examples, the following dyes are described: salicylic acid \sM 3-oxybenzidine --> 1-(41-oxy-31-carboxyphenyl)-, 1-(31-nitrophenyl)- or 1 - (41 - b  - oxyethoxyphenyl) - 3 - methyl - 5 - pyrazolon or 3-methyl-5-pyrazolone; 4-sulphonamido- or 4-nitro-2-aminophenol --> resorcinol \sM 3-oxybenzidine --> 1-(41-oxy-31 - carboxyphenyl) - 3 - methyl - 5 - pyrazolone; salicylic acid \sM 3-oxybenzidine --> 1-(31-aminophenyl) - 3 - methyl - 5 - pyrazolone --> 1 p  - (41 - oxy - 31 - carboxyphenyl) - 3 - methyl - 5 - pyrazolone.  In example (4), cotton is dyed with salicylic acid \sM 3-oxybenzidine --> 1 - (41 - oxy - 31 - carboxyphenyl) - 3 - methyl - 5 - pyrazolone and after-treated in the dye-bath with complex copper tartrate. Specifications 12932/15, 102,881, [both in Class 2 (iii)], and 455,274 are referred to.  The Specification as open to inspection under Sect. 91 comprises also the use of pyrazolones other than 3-alkylpyrazolones, e.g. those containing a carboxyl group in the 3-position.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1519944 Automatic control of RF power PHILIPS' GLOEILAMPENFABRIEKEN NV 5 April 1977 [8 April 1976] 14311/77 Heading G3R [Also in Divisions H3-5] RF power (e.g. a 9960Hz, a.m, modulated DVOR carrier) is fed to distribution and switching points 5, 8 (e.g. for respective distribution to the even antennae and to the odd antennae) via #/4 lines 4, 7 across PIN diode loads 33, 34. By applying half cosine and half sine control signals 31, 32 at double the switching frequency to the loads, their impedances are varied correspondingly and the power transfer from one antenna to the next is made gradual. The control signals 31, 32 are fed to difference amplifiers 39, 40, having the envelope of the output signal fed to the subtraction input and providing retro-control of the load impedance. The varying loads however are 'seen' at the carrier generator 16 as a varying load, tending to cause frequency drift. To overcome this, the cosine and sine control signals are summed (14) and used, via a retro-control circuit comprising difference amplifier 42 and feedback path 43, to amplitude modulate (19) the carrier.

Abstract: 1281762 Antiskid braking systems NORTH AMERICAN ROCKWELL CORP 24 March 1970 [5 June 1969] 14322/70 Heading F2F In a vehicle antiskid braking system a valve 78 is closed by a solenoid 76 on reception of a signal indicative of a " low " condition of skid to isolate a chamber 122 of a control device 36 from an engine intake manifold 87, a second valve 84 being actuated by a solenoid 82 to connect chamber 122 to atmosphere on reception of a signal indicative of " high " degree of skid, a diaphragm 108 thus being moved rightwardly so that a ball 92 closes communication between a pressure source 26 and rear wheel cylinders 22, 24, whereafter a piston 102 connected by a rod 106 to diaphragm 108 moves further rightwardly increasing the volume of a chamber 124 to relieve the pressure at the rear brakes. As shown, signals generated at the front wheels 10, 12 by transducers 48A, 48D are fed respectively to combination rectifier and filter network units 50, 52 which produce D.C. voltage outputs proportional to the wheel speeds, the output from unit 52 being passed to unit 50, the rear wheel transducers 48C, 48D being similarly connected to units 58, 59. The signal from unit 50 is passed to one side of two differential comparators 64, 68 by way of isolation resistors 62, 66 respectively, the other sides of comparators 64, 68 being fed with signals from unit 58 through variable attenuators 70, 72, the output of attenuator 70 being more negative than attenuator 72. When the rear wheel velocity becomes slightly less than that of the front wheels, comparator 64 generates a signal, triggering an amplifier 74 and energizing solenoid 76. If the rear wheel velocity further decreases, the voltage difference across terminals 68A and 68D of comparator 68 causes amplifier 80 to be triggered, thereby actuating solenoid 82.

Title: Oil-soluble phenolic condensates
IPC: C08G8/28
Filed: 1935-05-16
Abstract: Oil soluble phenol-aldehyde resins are prepared using (1) a phenol higher than cresol in the homologous series, e.g. amyl- and butylphenols, (2) more than an equimolecular proportion of the aldehyde, and (3) no strong alkali or mineral acid catalyst, and the condensation is preferably effected in the presence of an acidic natural resin, turpentine or dipentene.  The product may then be heated with an acidic natural resin, if none has previously been added, and reacted with a polyhydric alcohol such as glycerol to give a resin of low acidity; alternatively, glycerol mono-or di-resinates may be heated with the initial condensate.  The resins are useful in the manufacture of coating compositions.  According to the examples: (1) amylphenol is heated under pressure with formaldehyde solution in the presence of rosin and a small amount of zinc acetate, glycerol is then added and the temperature maintained at 240 DEG  C. for 12 hours; (2) p-tert-amylphenol, formaldehyde solution, turpentine and a little zinc resinate are heated under pressure or at boiling temperature under reflux for some time and the product then heated as in (1) after addition first of rosin and then of glycerol; (3) butylphenol is reacted with formaldehyde by the processes of (1) and (2); (4) p-tert-amylphenol is condensed with aqueous formaldehyde in the presence of zinc acetate, if desired with the addition of turpentine, and the product then heated at 200--260 DEG  C. with ester gum, a solvent being present if desired.  Other catalysts mentioned are zinc abietate, linoleate, oleate, stearate, tungate and benzoate, and the corresponding salts of cobalt, manganese, sodium and potassium.  U.S.A.
