Title: Improvements in or relating to electric remote control units employing thermionic valve circuits
IPC: H03K5/04
Filed: 1950-05-25
Abstract: 686,697. Valve relay circuits. LORD, R. E. C., and SIDE, G. A. May 25, 1950, No. 13181/50. Class 40 (vi). An electrical remote control unit comprises a diode valve in which the duration of a first time period which precedes the starting of associated electrical apparatus is determined by the time required for the valve to attain full emission to actuate a relay and the duration of a second time period which precedes the stopping of the apparatus is determined by the time required for the valve emission to fall substantially to zero. The Figure shows a control circuit in which when a remote switch connected across leads 1, 2 is made relay 3 operates and the associated contacts 12 and 16 change-over. Relay 15 operates via contacts 10, 16 and 14 and its associated contact 7 connects H.T.+ terminal 9 to the " start " lead 8 of the apparatus to be controlled. A circuit is also completed for the diode heater circuit from H.T.+ via contacts 10, 16, 17, resistors R1 and VR2 to H.T. - terminal 4. After a period determined by the setting of resistor VR2 the diode 13 reaches full emission so that relay 10a operates and changes over contact 10 and opens contact 17. The diode heater current is maintained via contact 10 and resistor R2. When the remote switch across leads 1, 2 is broken relay 3 releases contacts 12 and 16 change-over, relay 10a is released and relay 11a operates, contact 11 is made and its contact 14 completes the circuit to operate relay 5a which closes contact 5 and applies positive battery to the " stop " terminal 6. The heater circuit is now completed from H.T.+ via resistors VR1, R3 and R2 to H.T. - and the additional resistance in circuit produces a fall in the emission of diode 13 until after a time dependent on the setting of resistor VR1, relay 11a releases, contact 11 opens and disconnects the diode heater circuit. Relay 5a also releases and disconnects positive battery from the " stop " terminal 6.

Title: The manufacture of new aromatic amino-metal-mercapto acids or salts thereof
IPC: C07C323/58
Filed: 1925-05-22
Abstract: Acyl derivatives of aromatic amino-metalmercapto acids or salts are prepared either by acylating the aromatic amino-metalmercapto compound itself or by first acylating the aromatic aminomercapto compound and then introducing a metal into the mercapto group.  The products, which possess therapeutic properties, are stable in aqueous solution.  According to the examples, (1) an alkaline solution of 4-amino-2-argentomercaptobenzene-1-carboxylic acid (described in Specification 201,302) is treated with acetic anhydride or phosgene, the precipitate dissolved in soda, and alcohol then added to throw down the sodium salt of 4-acetyl-amino - 2 - argentomercaptobenzene-1-carboxylic acid or of the diphenylurea compound respectively; (2) the treatment of the sodium salt of 4-amino-2-auromercaptobenzene-1-carboxylic acid (described in Specification 157,853) with phosgene gives a diphenylurea compound, the solutions of which in alkalis and ammonia are stable to boiling; (3) the sodium compound of 4-amino-2-auromercaptobenzene-1-carboxylic acid, treated with m-nitrobenzoyl chloride and the nitro group then reduced with ferrous salt in alkaline solution, yields 4-m-aminobenzoylamino-2-auromercaptobenzene-1-carboxylic acid, which by interaction with phosgene forms the di-(4-m-aminobenzoylamino-2-auromercaptobenzene-1-carboxylic acid)-urea; (4) by the action of m-nitrobenzoyl chloride on m-amino-p-toluic acid, followed by reduction with zinc dust and reaction of the product with phosgene in alkaline solution, sym-di-(m-aminobenzoylamino-p-toluic acid)-urea is obtained; treatment with phosphorus pentachloride gives the corresponding acid chloride, which, by interaction with the sodium salt of 4-amino-2-auromercaptobenzene-1-carboxylic acid, yields the sym-di-(4-m-aminobenzoylamino-p-toluylamino-2-auromercaptobenzene - 1 - carboxylic acid)-urea; (6) a solution of p-aminomercaptocinnamic acid (obtained by reducing p-nitromercaptocinnamic acid) in caustic soda is treated with potassium auribromide; the precipitated gold compound is dissolved in caustic soda and phosgene led in; the product comprises the diphenyl-(auromercapto-p-acryl)-urea; (7) the sodium salt of 4-amino-2-thiobenzene-1-sulphonic acid is treated with phosgene, neutralized, aluminium amalgam added, and the resulting sym-di-(2-mercaptobenzene-1-sulphonic acid)-urea treated with potassium auribromide to give the gold compound.
