Patent GB-881616-A (GB)
Title: Improvements in the production of 1-aryl-4, 5-dihalogen-pyridazones-(6)
Inventor: HENSEL HANS RUPRECHT
IPC: C07D237/16
Filed: 1960-06-21
Abstract: 1-Aryl-4,5-dihalopyridazones-6 of the formula <FORM:0881616/IV (b)/1> in which X represents a chlorine or a bromine atom and R represents a phenyl or naphthyl radical which may or may not be substituted are prepared by (1) reacting a mucochloric or mucobromic acid in aqueous mineral acid solution at room temperature with a phenyl or naphthyl hydrazine RNHNH2 and treating the reaction product with concentrated sulphuric acid or by (2) heating a mucochloric or mucobromic acid in aqueous mineral acid solution with a phenyl or naphthyl hydrazine RNHNH2.  In the first method the intermediate hydrazone may be isolated and then cyclised by stirring with the sulphuric acid at room temperature.  The preferred mineral acid is hydrochloric or sulphuric acid.  Unsubstituted pyridazones may be nitrated in the aryl ring and subsequently reduced to the amino compound.  The aryl hydrazine may be substituted in the ring by substituents that do not interfere with the mucohalic acid such as methyl, methoxy, carboxy, sulphonic acid, nitro, phenylamino, acetylamino, oxalylamino and benzylamino.  Examples describe the preparation by method (1) of the nitrophenyl, 3-amino-6-sulpho-phenyl, acetylamino-phenyl, carboxyphenyl and nitrotolyl - dichloropyridazones with isolation of the intermediate hydrazones and the preparation by method (2) of phenyl, tolyl, sulphonyl and sulphonaphthyl dichloropyridazones and phenyl and tolyl dibromopyridazones.

Abstract: 1,171,035. Valves. CONTROLS CO. OF AMERICA. 9 May, 1968 [23 June, 1967], No. 22022/68. Heading F2V. A gas valve has the safety closure member 17 mounted with lost-motion between rings 24, 26 on the stem 22 of armature 35. In the open position shown, the magnet 37 is energized by the pilot flame to retain the armature against spring 34. An auxiliary spring 54 in extension 50 of main stem 52 maintains the closure member 17 unseated against the action of light spring 30. Upon withdrawal of knob 57, stem 56 is moved away from closure member 17 and the latter is seated by spring 30. Spring arms 62 snap under the closure member to prevent re-opening of the latter by reverse movement of knob 57 until the magnet releases the armature and the latter returns the arms to the inoperative positions.

Steam or other gas under pressure enters through an inlet 2 and escapes past one or more diaphragms 7, 8, 9, Figs. 1 and 3, into an amplifying horn 3, thereby vibrating the diaphragms. These are adjustably mounted on a central pin 4 attached to a mounting plate 5 having apertures 6 to allow the passage of the steam or other gas. The casing 1 may be of stepped form, Fig. 2 (not shown). Discs 16, 17, 18 whose peripheries form annular nozzles with the casing 1 also may be mounted on the pin 4, Fig. 3. In a modification, Fig. 4, the inlet 2 has a nozzle 25 to direct the incoming gas against the centre of a diaphragm 19 which is secured at its periphery between a locating ring 24 and a ring 20 attached to the casing 1 by struts 21.

Abstract: 500,622. Automatic control systems. REYROLLE & CO., Ltd., A., LINSTOW, F. N., and RITSON, T. Aug. 11, 1937, No. 22049. [Class 38 (iv)] Temperature.-In a hot water heating installation in which the hot water is fed to the radiators directly from an electric water heater A without the use of a hot water storage tank the electrical load is controlled in accordance with the heat requirements of the installation by an electric motor E which may control movable electrode shields in the heater, means being provided for rendering the operation of the control apparatus intermittent to reduce hunting and further means being provided for preventing the electrical load from exceeding a predetermined value. The motor E is energized to increase and decrease the load by the closure of the respective switches F2, G2 controlled by coils F and G. Starting up may be effected by a time switch O which energizes main control relay M if the apparatus is in its minimum load position. Contacts M1 then close and S closes S1, S2 to energize motor c, which closes the main circuit-breaker P. A " variostat " operative in response to the temperature of the water in the flow pipe of the heater and corrected for the outside temperature is arranged to close contacts K3 in series with F when more heat is required. F is then energized to increase the load. When the maximum desired load is reached the load limit relay H opens HI and closes H2 so that G is energized, motor E is reversed and G3 is closed to energize L which then opens L2. Energization of the coils F, G is then controlled by contacts J1 which are closed for short periods alternating with long intervals during which they are open, by the "impulse duration " relay J so that hunting is reduced during control of the load by the variostat through coils F and G. Switching off of the apparatus is effected by the time switch 0 which causes de-energization of M and L G being continuously energized to reduce the load to its minimum value. When contacts E2 are closed and trip coil T is energized to open the circuit-breaker P auxiliary contacts 02 are closed after a time delay by the time switch 0 if the circuit-breaker is not tripped. The coils F, G are provided with interlock contacts F1 and G1. Protective devices comprising overload relays U, earth leakage relay V, safety thermostat W operative at excessive water temperature and safety pressure switch operative in response to excessive pressure in the heater are provided and are arranged to operate respective alarms U2, V2, W2, X2, and to trip the circuit-breaker when energized. The control circuit may be cut out by opening a switch Z. Coils F and G are provided with overload and thermal trip devices which may also operate an alarm N. The installation may be started by hand, a manual changeover switch being operated so that when starting is due to take place the time switch O only sounds the alarm N. The individual pipes to the radiators &c. may be provided with thermostatically operated valves.
