Patent GB-832018-A (GB)
Abstract: 832,018. Ignition systems. ECONOMY ENGINE CO. Oct. 11, 1957, No. 31810/57. Classes 7(2) and 7(4) A method of igniting a combustible gas mixture fed to a plurality of combustion chambers of an internal-combustion engine, each chamber having a pair of electrodes included therein, with an individual current limiting means connected in series therewith, comprises providing and maintaining continuously during operation current impulses at each of the series of electrodes and current limiting means and thereby limiting the current flow to each of the pairs of electrodes so as to prevent sparking conditions which are a function of gas compression pressure at one of the pairs of electrodes from adversely affecting sparking conditions at the other pairs. Sparking may be maintained at the electrodes of each spark plug at all times during the operation of the engine. However, it is not necessary that the continuous sparking shall be maintained throughout each cycle. It is necessary however that a series of individual sparks be supplied for each explosion and a continuous spark is supplied throughout a. substantial portion of the combined compression and power strokes. It is preferred however to maintain sparking at the electrodes of each of the spark plugs at all times and to arrange matters so that when peak compression pressure is achieved in any given cylinder a spark of sufficient intensity toignite the compresssed gases is produced. The spark voltage varies in accordance with the pressure prevailing at each plug and consequently is somewhat lower than peak voltage when the pressure is low. In Fig. 1 a resistor 5 for example of 10 or 20 megohms is associated with each sparking plug. Each plug is mounted in an ignition chamber 3 which in turn is mounted in the cylinder wall so as to be in communication with the combustion chamber. The coil 8 is associated with a vibrator 13. In Fig. 2 the ignition system is powered by an alternating current generator 20. Each plug 21 is connected in series with a capacitance or inductance 24. Resistors may be used instead of the capacitances. In a modification of Fig. 1 an electric motor drives an alternator associated with a transformer the transformer secondary supplying the ignition impulses to the sparking plugs. In Fig. 4 a transistor 51 is associated with the transformer 52. The transformer includes a control winding 60. When the flux in the core reaches its maximum value the flux change becomes zero. This causes the base bias current from the winding 60 to begin to reverse and start the negative or cut-off portion of the current cycle. With decreasing flux in the core of the transformer 52 reverse voltages are produced and a resulting rapid collapse of flux in the core produces a high peak voltage in the secondary 61. The ignition chamber is not essential. Where used the ignition chamber may be formed by shaping the upper portion of the cylinder wall or by the use of a deeply recessed spark plug.

Title: Locating a towed marine object acoustically
Inventor: BAECKER DONALD RAY
IPC: G01S15/88
Filed: 1983-09-14
Abstract: A system and method for determining the position of towed marine object relative to a towing vessel. The system comprises a towing vessel, a slave vessel, and the towed object. An acoustic transceiver is located on either the towing vessel or the slave vessel with an acoustic receiver located on the other vessel. One or more acoustic transponders are associated with the towed object. The distance between the towing vessel and the slave vessel is determined, for example, by radio navigation which is calibrated by a high precision range-range system. The acoustic transmitter emits an interrogation signal which causes the transducer(s) to emit a response acoustic signal which is recorded at the two receivers. Using the time for the response signal to reach each of the receivers and the velocity of sound in water, the distance of the transducer from each vessel is calculated. With the three distances the location of the transducer relative to the towing vessel is determined by trilateration. The system is especially useful for determining the horizontal profile of a towed seismic cable, where a series of transducers are located along the cable. The interrogation signal will interrogate each transducer sequentially and by trilateration of each transducer a very accurate representation of the horizontal profile is obtained.

Title: Aluminium chloride production
Inventor: ROBINSON MICHAEL
IPC: C01G49/10
Filed: 1984-07-23
Abstract: A process for the production of aluminium chloride from an iron-containing aluminous material such as, for example, bauxite comprises chlorinating the bauxite in a fluidised bed in the presence of excess carbon and diluted chlorine to selectively remove iron in the form of iron chloride and to produce a beneficiate, chlorinating the beneficiate to produce aluminium chloride, contacting the aluminium chloride in the vapour form with metallic aluminium to further reduce the iron chloride content, condensing iron chloride, and selectively condensing the purified aluminium chloride. The iron chloride removed at various stages of the processes is condensed from unwanted gases, revolatalised and oxidised to generate chlorine of a purity suitable for direct re-use. A number of further features such as the selective chlorination of the iron values in the presence of water vapour and the electrostatic treatment of the vaporous aluminium chloride are applicable to the process.

Title: Process and apparatus for killing bacteria and viruses in blood
Inventor: SWIFT THOMAS RICHARD
IPC: A61M1/36
Filed: 1986-04-30
Abstract: In a process for killing many bacteria and viruses in human and animal whole blood or in its component parts among which are serum and Factor 8, silver ions are introduced into the blood or blood components. In one method of operation, blood is introduced into a vessel (1), a pair of silver electrodes (2) is immersed in the blood, and a direct current from a source (3) which may be reversed at regular intervals is passed between the electrodes. The blood is gently stirred and the process allowed to run until the silver ions given off by the electrodes into the blood attain a level of up to several parts per million parts of blood. The power is then switched off and stirring continued, where after the blood is then transferred into a vessel (6) with a stirrer (6a). This vessel contains electrodes (7) connected to a DC power source (8). When the current flows between these electrodes, the silver ions or ionic compounds which they form with other chemicals in the blood are substantially removed from the blood and coat the cathode. When this process is completed, the blood is substantially sterile and is removed for storage or reintroduction to a patient. <IMAGE>
