Title: Process of chlorinating hydroxy triazines with thionyl chloride
Filed: 1951-08-28
Abstract: Chlorinated triazines are prepared by heating a hydroxy triazine in an inert organic solvent with thionyl chloride, preferably at a temperature of 110-160 DEG  C., e.g. by refluxing in a suitable solvent.  Optionally phosphorus pentachloride may be present as catalyst, a suitable amount being from 0.05-0.1 mol. per mol. of hydroxy triazine.  Excess thionyl chloride may be removed after the reaction, by vacuum distillation.  Suitable solvents are hydrocarbons and their halogenated and nitrated derivatives.  Specified triazines are the 3 : 5-dihydroxy-6-phenyl-, 3-hydroxy-5 : 6-diphenyl-, 3 : 5-dihydroxy-6-methyl- and 3-hydroxy-5 : 6-bis-(p-anisyl)-, 1 : 2 : 4-triazines and the 2 : 4 : 6-trihydroxy-, 6-hydroxy-2 : 4-diphenyl- and 6-hydroxy-2 : 4-di-p-tolyl-, 1 : 3 : 5-triazines and particularly the 2-alkyl- or aryl-4 : 6-dihydroxy-1 : 3 : 5-triazines.  The chlorinated triazines or the reaction mixture obtained from the chlorination may be reacted with an aminoanthraquinone to give a dye. In examples there are prepared according to the invention (1) 2-o-methoxyphenyl - 4 : 6 - dichloro - 1 : 3 : 5 - triazine; (2) 2 - o - tolyl - 4 : 6 - dichloro - 1 : 3 : 5 - triazine; (3) a solution of 2-phenyl-4 : 6-dichloro-1 : 3 : 5-triazine and (4) 2-chloro-4 : 6-diphenyl-1 : 3 : 5-triazine.  Guanamides.-o - Methoxyphenyl - dihydroxy - triazine and o-methylphenyl-dihydroxy-triazine (guanamides) are prepared by treating o-methoxybenzoyl- or o-methylbenzoyl biuret with aqueous potassium hydroxide. Biurets.-o-Methoxybenzoyl- and o-methylbenzoyl-biuret are prepared by treating the corresponding substituted benzoyl dicyandiamides with dilute hydrochloric acid.  Dicyandiamides.-o-Methoxybenzoyl- and o-methylbenzoyl-dicyandiamide are prepared by condensing the corresponding substituted benzoyl chloride with dicyandiamide.ALSO:Anthraquinone dyestuffs of the formul <FORM:0693540/IV (c)/1> and <FORM:0693540/IV (c)/2> are prepared by (1) reacting 1-aminoanthraquinone with 6 - (o - methoxyphenyl) - 2 : 4-dichloro - 1 : 3 : 5 - triazine in o - dichlorobenzene or nitrobenzene, and (2) reacting 4-methoxy - 1 - aminoanthraquinone with 6-phenyl - 2 : 4 - dichloro - 1 : 3 : 5 - triazine in nitrobenzene (see Group IV (b), for preparation of the triazines).

Title: Code receiver
IPC: G08B3/10
Filed: 1971-04-19
Abstract: 1287537 Selective signalling PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 April 1971 [27 Jan 1970] 20257/71 Heading G4H A code receiver comprises a code selection stage and a code indication stage, the latter comprising a plurality of indication circuits, each of which includes an indicator, there being provided a manually-operable two-position switch, having a rest position and a working position without locking, all indication circuits being interrupted in the rest position and being connected in the working position to the code selection stage, a delay device being actuated in the working position for temporarily switching on all indication circuits. Signals from an aerial are recognized to energize a combination of the inputs K1, K2, K3 to the circuit of Fig. 2. To switch this circuit on, manual switch S3 is moved to the other position from that shown. Inter alia, this makes transistor T5 conduct after a delay defined by charging of capacitor C2 during which the off state of transistor T5 resets bi-stables F1, F2, F3. The input signals at K1, K2, K3 selectively set bi-stables F1, F2, F3. Closing manual switch S1 lights three lamps L1, L2, L3 via the emitter circuits of transistors T1, T2, T3 (base current for these transistors being supplied via diodes D12, D22, D32 since transistor T4 is off), and permits capacitor C1 to charge. After a delay, this charge is sufficient to switch transistor T4 on, cutting off the diodes D12, D22, D32, so that now only those lamps will be lit whose associated transistors T1, T2, T3 are kept conducting by base current supplied via diodes D11 D21, D31 from bi-stables F1, F2, F3. Release of S1 switches off transistors T1, T2, T3 and therefore lamps L1, L2, L3. To reset the bi-stables F1, F2, F3, transistor T5 is cut off by manual closure of switches S1 and S2. Capacitor C2 which was charged during initial switch on is discharged via diode D5 when S3 is returned to the position shown for final switch off.

Abstract: 709,876. Electrically-tripped switches; control of A.C. motors. GENERAL MOTORS CORPORATION. Aug. 15, 1952 [Sept. 18, 1951], No. 20526/52. Classes 38(3) and 38(5) A switch for controlling a motor 20 having a starting winding 21 disconnectable by a centrifugal switch 23 and a running winding 22, comprises contacts 31, 32 bridgeable by a contact 35 resiliently mounted by a spring 36 against a shoulder on a plunger 33. The plunger 33 is pivotally connected at 41 to a lever 37 urged clockwise about a pivot 38 by a spring 42. Hence on depression of the plunger 33 to close the contact 35 the spring 42 is stressed, a bimetal detent 48 engaging the lever 37 to hold the switch closed. The motor circuit from line 53 is completed through contacts 31, 32, 35, a conductor plate 47, a heater coil 50 for the detent 48, and a terminal 52. On excess current through the motor the detent 48 flexes downwardly permitting the spring 42 to open the contact 35. In order to accelerate the flexing movement of the detent 48 and thus reduce the time the motor is subjected to the overload, the detent carries a magnetic post 60, which, together with a magnetic stud 62 and a pole plate 61 carried thereby and a part of the detent 48, forms a magnetic circuit magnetizable by the coil 50, the excess current causing the post 60 to be attracted towards the pole plate 61. To create a stronger electromagnet a winding in circuit with the coil 50 may be placed about the stud 62.
