Title: Process for the manufacture of amino-aryl-thiazole-compounds
IPC: C07D277/84
Filed: 1930-01-22
Abstract: Aminoarylthiazole compounds are manufactured by the action of chlorine or an agent yielding chlorine on thiourea derivatives of the general formula: aryl-NX-CS-NH2, where aryl indicates an aromatic residue, which may contain further substituents, and X hydrogen or an alkyl- or aryl-group.  The products, in the case in which X is hydrogen, when treated at a temperature above 100 DEG  C. with concentrated caustic alkali solution yield aminoarylmercaptans.  As agents yielding chlorine are specified sulphuryl chloride, sulphur chloride, sulphur dichloride and antimony pentachloride, and as diluents chlorobenzene, carbon tetrachloride and glacial acetic acid. In examples: (1) phenylthiourea is treated with sulphuryl chloride in chlorobenzene solution to produce 2-aminobenzothiazole, which may be converted to 1-aminophenyl - 2 - mercaptan; (2) o - tolylthiourea similarly yields 2-amino-4-methylbenzothiazole; (3) the same reaction is carried out using excess of sulphuryl chloride without any other diluent; (4) 4-ethoxyphenylthiourea is treated with disulphur dichloride in chlorobenzene solution, yielding 2-amino-6-ethoxybenzothiazole; (5) the same reaction is effected by means of antimony pentachloride; (6) 2-methyl-4-chlorophenylthiourea (obtained by heating 2-methyl-4-chloraniline hydrochloride with ammonium thiocyanate) is treated with chlorine or sulphuryl chloride in chlorobenzene solution, producing 2-amino-4-methyl-6-chlorobenzothiazole; 2-methoxyphenylthiourea is similarly converted to 2-amino-4-methoxybenzothiazole; (7) b -naphthylthiourea, treated with sulphuryl chloride in chlorobenzene solution, yields 6 : 7-benzo - 2 - aminobenzothiazole; (8) p - tolylthiourea is converted, by the action of sulphuryl chloride in chlorobenzene or carbon tetrachloride solution, into 2-amino-6-methylbenzothiazole; (9) asymmetrical phenylmethylthiourea is treated with sulphuryl chloride in chlorobenzene solution to produce 2-imino-3-methyl-2 : 3-dihydrobenzothiazole; (10) asymmetrical diphenylthiourea similarly yields 2-imino-3-phenyl-2 : 3-dihydrobenzothiazole. Specification 306,590, [Class 2 (iii), Dyes &c.], is referred to.

Title: Improvements in or relating to thermionic valve relay circuits
IPC: G05B11/01
Filed: 1950-01-30
Abstract: 672,046. Automatic voltage control systems. GENERAL ELECTRIC CO., Ltd., and MACKENZIE, R. B. Jan. 30, 1951 [Jan. 30, 1950], No. 2405/50. Class 38 (iv). [Also in Group XL (c)] A relay circuit comprises two valves cross connected as a trigger pair with an electromagnetic relay in the anode and cathode circuit of the two valves respectively so that when the input voltage applied to the grid circuit of one valve moves in one direction from a datum level the relay in the anode circuit is energized and when it moves in the other direction the relay in the cathode circuit is energized and the other relay released. The Figure shows a cross-connected pair of valves 8, 23 having a relay 20 in the anode circuit of valve 8 and a relay 24 in the cathode circuit of valve 23. An A.C. input voltage which it is requred to maintain constant is applied at terminals 1, 2 via two gas-filled constant voltage tubes 3, 4 to an input resistor 5. The voltage across resistor 5 is rectified by the rectifier 9 filtered in circuit 11, 11<SP>1</SP> and applied to trigger valve 8. If the input voltage rises above a predetermined datum level the anode current of valve 8 increases and relay 20 is energized, the fall in potential at the anode of valve 8 is applied to the control grid of valve 23 to reduce the cathode current in this valve and thus to release relay 24. If on the other hand the input voltage falls below the datum level the anode current in valve 8 falls and relay 20 is deenergized, the rise in the anode voltage of valve 8 causing increased cathode current in valve 23 so that relay 24 is operated. The circuit may be used to maintain the input voltage constant by using the contacts of relays 20, 24 to control the direction of rotation of an electric motor arranged to drive a circuit element to revert the input voltage to its datum level on departure therefrom. The variable resistors 21, 25 are coupled together to vary simultaneously but in opposite directions thereby enabling the sensitivity of the circuit to be varied.

Title: Improvements in or relating to annunciator or alarm systems
IPC: G08B23/00
Filed: 1955-01-28
Abstract: 806,881. Electric selective signalling systems. PANELLIT Inc. Jan. 28, 1955 [May 17, 1954], No. 2636/55. Class 40 (1). In an alarm system for indicating the presence of one or more abnormal conditions in a group of closely related variables, two different alarm indications are provided for each variable, one indicating that the variable is the first of a series to become abnormal subsequent to the first variable becoming abnormal. Two units 2, 21 of a series are shown, each being associated with one of the related variables, unit 2 having normally open alarm contacts 20 and unit 2<SP>1</SP> normally closed alarm contacts 20<SP>1</SP>, which are operated when the corresponding variable becomes abnormal, to energize alarm relay A or de-energize A<SP>1</SP> from the supply 18. If relay A is the first to be operated it is held through contacts Al, B1, the relay B being normally energized. The lock-out relay LO becomes energized through normallyclosed reset switch 14, contacts A3, A2, B2, and current limiting resistor 27. A red light 6 is energized through normally closed reset switch 14 and acknowledge switch 12, contacts L05, B6, and flashing switch 30, which is driven by a motor 32. The motor 32 and an alarm bell 10 are energized through contacts B4 and A4. The lock-out relay LO of the first unit to be energized renders the relays LO of the other units inoperative through contacts LO4 and thus prevents the red light 6 from being energized, whereby only the red light in the first actuated unit is energized and in subsequently actuated units a white light 8 is energized. When the acknowledge button 12 is momentarily depressed relay B is de-energized and whichever lamp 6 or 8 is energized is now energized through contacts B7 or B9 to provide a steady light. If the relay A was the first of the series to become energized the return of the alarm contacts 20 to normal does not de-energize relay A so that once energized, the red light 6 may only be extinguished by operating the reset switch 14, which clears the system for a subsequent series of alarms. If alarm contacts 20 are still abnormal when the switch 14 is opened, the red light is extinguished and the white light 8 energized. In other relays A which are actuated and with a white light lit in a steady condition, the return of the alarm contacts to normal de-energizes relay A and extinguishes the light 8. A switch 16 is provided for testing the lights. In some cases as in unit 21 it is more convenient to have normally closed alarm contacts 20<SP>1</SP>, the alarm relay A<SP>1</SP> being energized when the associated variable is in a normal condition.

The heated presser member is supported by a ball 54 at the end of an arm slidable in a holder 50 supported on a vertical rod 52 as described in the parent Specificaton, a second arm 60 preventing the heater from tipping excessively by engagement with a handle 58 on the presser. The ball 54 is held between a removable bracket 56 and a plate 26 integral with the handle 56. The heating and pressing members are supported from this plate, a number of plungers 30, the reduced ends of which are secured in the plate by pins 36, being riveted to a resilient plate 18, the plungers normally engaging steps 34 formed on a central member 16 heated by an electric resistance 20.

In operation, while the wipers 12 are still over the shoe bottom, the operator swings the upper-pressing device into position and lowers it by treadle as described in the parent Specification, bringing the plate 16 into pressing and holding relation to the upper margin as shown in Fig. 3. The wipers may then be retracted and pressure on the treadle increased, causing the plate 18 to leave the steps 34 and engage the upper near the edge of the last, both the pressure and the heat being less than those of the plate 16. After a sufficient interval, the treadle is released and the work is removed.
