Patent GB-2469131-A (GB)
Title: Advanced excitation of an electric machine
Inventor: DAWE ROGER MICHAEL
IPC: H02P6/08
Filed: 2009-04-04
Abstract: As the permanent-magnet rotor of an electric machine accelerates, it induces an increasing back-emf in a winding of the machine. It therefore becomes increasingly difficult to drive power into the electric machine. The invention is a method of controlling an electric machine in which a winding of the electric machine is excited in advance of zero-crossings of back emf in the winding by a fixed advanced time T_ADV over a range of speeds of the electric machine. Therefore the advance angle increases with the speed of the rotor. The fixed advance time T_ADV may vary with excitation voltage. A battery may supply the excitation voltage and as the battery pack discharges the excitation voltage and hence the advance time varies so that power output of the electric machine remains constant. The electric machine may be a motor and is suitable for use in a vacuum cleaner.

Title: Improvements in spray carburettors for internal combustion engines
IPC: C01B13/02
Filed: 1932-04-09
Abstract: 383,536. Spray carburetters. BECKER, R. VON, 241, Dieburgerstrasse, Darmstadt, Germany, and DJORDJEVITCH, J., 143, Avenue Victor Hugo, Paris. April 9, 1932, No. 10175. Convention date, April 9, 1931. [Class 7 (iii).] An auxiliary fuel supply pump which is actuated by an arm on the throttle valve, has a fuel admission port which is opened only at a predetermined position of the throttle valve, and an air escape port which is closed not later than the closing of the fuel admission port. Fuel is fed to an auxiliary nozzle 9, Fig. 1, by a pump 7 in which is a spring-pressed plunger 10 on which bears an arm 15 connected to the throttle valve 1. The pump receives fuel from a float chamber 3 through a passage 13 when the throttle valve is closed and as the valve is opened the passage 13 and an air escape opening 14 are closed, and fuel is delivered at the nozzle, the compression of the air in the cylinder causing a prolonged delivery. In a modified construction, Fig. 5, the air escapes through a passage 19 located in the plunger head 32 and closed during the forcing stroke by a pin 20 actuated by the arm 31 on the throttle valve. To enable the nozzle 19 to supply extra fuel when the engine is running under full load, a passage 25 in the plunger, Fig. 6, places the port 13 in communication with the interior of the pump when the throttle is fully open and the plunger is in its lowermost position ; thus fuel flows to the nozzle 9 from the float chamber. In the modification shown in Fig. 4, a port 16 opens the interior of the plunger to the atmosphere and communicates with the port 13 when the plunger is depressed at full throttle opening.

Title: Improved processes for making compounds containing heavy metals and sulphhydryl groups from keratinates
IPC: A61K38/01
Filed: 1933-04-05
Abstract: Heavy metal compounds of mercaptokeratinates which are useful therapeutically are prepared by first forming the zinc compounds, then decomposing them with hydrogen sulphide, and finally treating the resulting mercaptokeratinic acids with compounds of heavy metals. The zinc compounds are obtained by hydrolyzing materials containing keratin with acid in excess until a jelly is produced, e.g. by the process described in Specification 370,295, reducing the product by addition of zinc, and neutralizing to precipitate the zinc compounds. As heavy metals are mentioned silver, gold, mercury, copper, lead, antimony, arsenic and bismuth, and their compounds include organo arsenic and antimony compounds.  Before adding arsenic, antimony or bismuth compounds, the combining capacity of the mercaptokeratinic acid may be estimated by titration with silver nitrate until no further reaction occurs with sodium nitroprusside.  In the case of the preparation of the gold compound, the keratinic acid solution may first be saturated with sulphurous acid.  According to the examples, (1) hair is treated with 20 per cent hydrochloric acid until converted into a gelatinous mass, zinc dust added in portions, and the zinc compound precipitated by neutralization with soda lye; (2) the keratinate prepared according to the process of Specification 370,295 is dissolved in hydrochloric acid, zinc added and the product neutralized; (3) hydrogen sulphide is passed into an p  aqueous suspension of the zinc compound of (1) or (2), the zinc sulphide filtered off, and the mercaptokeratinic acid isolated by evaporation in vacuo; (4) the acid of (3) is treated in aqueous solution with sodium aurichloride, silver nitrate, mercury acetate, copper acetate, lead acetate, sodium arsenite, potassium pyroantimonate, potassium antimonyl tartrate, bismuth ammonium citrate, gold trichloride (in the presence of sulphur dioxide), p-acetylaminophenylarsonic acid, p-acetylaminophenylarsine oxide, bismuth ammonium citrate, bismuth tartrate or bismuth nitrate, to give the corresponding heavy metal compound which either settles out or is precipitated by the addition of an organic agent, e.g. methyl or ethyl alcohol.  Specification 357,189 also is referred to.  The Specification as open to inspection under Sect. 91 describes also the preparation of any of the heavy metal compounds after first determining the combining capacity of the acid and contains a further example of the treatment of the above mercapto-keratinic acid with gold trichloride in the absence of sulphur dioxide. This subject-matter does not appear in the Specification as accepted.
