Title: Identifying the operation of a specified type of appliance
Inventor: DONALDSON JAMES
IPC: G01R21/00
Filed: 2009-07-30
Abstract: A method of identifying the operation of an electrical appliance comprising an induction motor involves plotting the real power values against the reactive power values over a time period of interest, where the plotting of a circular arc identifies operation of at least one appliance has occurred. The real and reactive power values are related to the total real and reactive power respectively supplied to one or more electrical appliances as a function of time and the time period of interest may be the period of power variation between the appliance being switched on and reaching steady-state operation. Identification of the operation of a particular type of appliance, dependent on a utility supply such as electricity, gas or water, is achieved by comparing the plotted arcs with predetermined plots for specific appliances. This allows a user to monitor energy use, in their home for example, and to identify the appliances that use the most power.

Title: Improvements in or relating to the preparation of sulphanilamido heterocyclic compounds
IPC: C07D213/76
Filed: 1946-04-02
Abstract: The alkali metal salt of a sulphanilamido heterocyclic compound is prepared by adding an excess of aqueous alkali metal hydroxide solution to an N-acyl-sulphanilamido-heterocyclic compound, heat-distilling the mixture to effect removal of the acyl group and to form an aqueous alkaline solution of the salt of the sulphanilamido heterocyclic compound, and then recovering the salt, e.g. by salting out.  If a crude N-acyl-sulphanilamido heterocyclic compound is used, volatile impurities such as the excess of condensing agent are removed with the water during the p distillation which may be effected with steam.  The N-acyl-sulphanilamido heterocyclic compound may be prepared by condensing N-acetyl-sulphanilyl fluoride, N-acetyl-sulphanilyl chloride, N-formylsulphanilyl chloride or N-carbonyl-bis-(sulphanilyl chloride) with sulphathiazole, sulphapyridine, sulphapyrazine, sulphadiazine, sulphaquinoline, sulphaoxazole, sulphamethylthiazole, sulphabenzthiazole or sulphabenzoxazole in the presence of a condensing agent such as pyridine, picoline, collidines and quinoline.  In examples: (1) aminothiazole is condensed with N-acetyl-sulphanilyl chloride in presence of a -picoline and the product steam-distilled with sodium hydroxide solution to remove the a -picoline and convert the compound to the sodium salt of sulphanilamido thiazole, which is removed by adding sodium chloride and cooling; (2) aminopyridine is condensed with N-acetyl sulphanilyl chloride in presence of a -picoline and the product steam-distilled after adding sodium hydroxide solution; the a -picoline is removed and the compound converted to the sodium salt of sulphapyridine, which is removed by adding sodium chloride and cooling; (3) sodium sulphopyrazine is formed similarly from 2-aminopyrazine; (4) N-formyl sulphanilyl chloride is used instead of the N-acetyl derivative in (1); (5) carbonyl-bis-(p-aminobenzene sulphonyl chloride) is used in (1) instead of N-acetyl sulphanilyl chloride. Carbonyl-bis-(p-aminobenzene sulphonyl chloride) is made by condensing urea with aniline and reacting the product with chlorosulphonic acid.  Specification 575,005 is referred to.

Title: Device for controlling a winch
IPC: F15B13/01
Filed: 1972-03-07
Abstract: 1350867 Controlling winch brakes SOC ANON POCLAIN 7 March 1972 [17 March 1971] 10639/72 Heading B8B [Also in Division F2] A device for controlling a winch coupled with an hydraulic drive motor 1 reversibly driven through conduits 9, 11 and 10, 14 and a three position distributor 15 from a fluid pump 12, comprises a safety brake 2 normally applied by a spring 4 but releasable by an hydraulic jack 5, and a calibrated valve 16 which maintains sufficient pressure in the jack 5 to release the brake irrespective of the size of load being lifted by the winch. In the distributor position shown, the drive to the motor 1 is blanked off, and a conduit 18 from the operating chamber 5a of the jack 5 is open through conduits 11-14 to the fluid tank 7, whereby the spring 4 applies the brake 2. For wind up drive to the motor 1 pressure is supplied to the conduits 9, 11 18 and 19 and the pressure builds up until there is sufficient to displace a slide 20 against a spring 17 in the calibration valve 16, whereafter the pressure fluid is able to pass from a chamber 25 to a chamber 23 in the valve 16 and to the motor 1, the jack 5 by this time having been operated to release the brake 2. The pressure required to operate the jack 5 is controlled by the strength of the selected spring 17, such that the said pressure is reached before the slide 20 is displaced. For lowering a load, the motor 1 is reverse driven via the appropriate distributor position and the load is lowered unless the load overruns the motor whereupon the pressure in the conduit 10, 11 18, 19 is reduced and the slide 20 closes the return path from the motor and the brake is applied until the pressure builds up again. In the embodiment of Figs. 2, 3, 4 (not shown) the conduit supplying fluid for displacing the calibration valve slide is connected to the motor conduit between the distributor valve and the calibrative valve, a further three position distributor valve being placed in the motor conduit between the pump and the first said distributor-valve, for coupling another piece of hydraulic apparatus into the system. Also the conduit leading to the brake releasing jack passes through a two position distributor mechanically controlled through a cam and follower arrangement in response to the position of the first said distributor valve.
