Title: Packaging a beverage to incorporate a floatable froth producing insert
Inventor: PURDHAM ROBERT
IPC: B65D17/34
Filed: 1997-01-08
Abstract: A method of packaging a beverage, especially beer, to incorporate a floatable froth producing insert comprises charging an open topped container 10 with beverage 6 to form a headspace 15 and including a hollow insert 1 that floats on the beverage. The insert has at last one restricted aperture 7, and is ballasted so that the aperture is submerged in the beverage when floating naturally. The container is then sealed, and the headspace pressurised to a pressure greater than atmospheric. During the pressurisation stage, the insert is preferably raised so that the aperture is above the level of the liquid, so that it becomes filled with gas at the same pressure as the headspace. The insert may be raised during pressurisation by rotating the container to subject the insert to a centrifugal force so that it abuts against the container wall, or it may be raised by a magnetic force. Alternatively, the insert may be kept at a raised position on the container wall using adhesive. The insert is then lowered so that it floats naturally on the beverage with the aperture submerged. When the container is opened, the gas in the insert is jetted out of the aperture into the beverage to develop froth. Beverage packages are also disclosed that include inserts with one aperture so arranged as to cause rotation of the insert during the jetting of the gas, or with two apertures arranged so that rotation of the insert is restricted during the jetting. An insert is additionally disclosed with a spherical outer surface and a wall of varying thickness serving to ballast the insert with the aperture below the beverage.
Patent GB-2310662-A (GB)
Title: Production of trialkyl phosphites from phosphorus trichloride and alcohol using a particular combination of amine base and alkyl- or alkylene-aromatic solvent
Inventor: OHLENDORF WOLFGANG
IPC: C07F9/141
Filed: 1997-01-23
Abstract: A process for the production of symmetrical trialkyl phosphites (ie phosphorous acid trialkyl esters) comprising reacting phosphorus trichloride and an alcohol in the presence of an auxiliary base (as an acid binding agent) and a solvent is characterised by the following features:-  (1) the alcohol has an alkyl group and a hydroxy group (the alkyl group being the same as the alkyl group of the trialkyl phosphite to be produced); (2) the auxiliary base comprises at least one alkyl amine having more than 10 carbon atoms (eg a di- or tri-alkylamine); and (3) the solvent comprises at least one alkyl- or alkylene-aromatic compound (eg mono-, di-, tri- or tetra-alkyl benzenes or tetrahydronaphthalene  tetralin) having more than 50 wt. % of aromatic carbon atoms, a molecular weight of from 106 to 150 and a boiling point of below 220{C at standard pressure. The advantage of these conditions is that the reaction proceeds in a homogeneous liquid phase without the production of solid reaction products (such as the hydrochlorides of conventional bases in conventional solvents). The reaction product may be separated in a distillation column having a small operating hold-up (ie short residence column) into a head product (consisting essentially of trialkyl phosphite and alcohol) and a bottom product (consisting essentially of solvent, auxiliary base and hydrochloride thereof), thereby avoiding the need for a filtration or washing stage and consequential reduction in trialkyl phosphite yield.

Title: Method for monitoring the performance of a NOx trap
Inventor: HEPBURN JEFFREY
IPC: F01N13/02
Filed: 1997-10-15
Abstract: A method and apparatus for on-board monitoring of NO x trap 32 performance is proposed that uses two HEGO sensors 34,36, one positioned upstream of the NO x trap, and the other positioned downstream of the NO x trap. When the engine A/F is reduced from lean to stoichiometric or rich operation to regenerate or purge the NO x trap 32, the difference in the time it takes for the upstream and downstream HEGO sensors 34,36 to switch from a lean to a rich indication provides a quantitative measure of the amount of NO x that was stored on the NO x trap during the previous lean period of operation. This measure is related to an estimated amount of NO x produced by the engine to infer the operating performance or efficiency of the NO x trap. The difference in the output voltage of the two sensors 34,36 is compared with a predetermined value to determined when to terminate the NO x purge. When the efficiency drops below a predetermined value the time that the engine is run in a lean cruise mode is reduced. If the time is reduced below a minimum time interval, a sulfur purge is performed. If sulfur purges are required more often than a predetermined repetition time, the lean cruise mode is terminated and an indicator lamp is energized.

Title: A watchdog circuit for a mobile phone battery charging system
Inventor: BANKS ANTHONY PAUL
IPC: H04B7/26
Filed: 1999-03-20
Abstract: A watchdog circuit ensures that that the charging control circuit of a mobile phone is set to a safe state in the event of a fault occurring. An alternating output (S) from the CPU of the phone causes periodic discharge of a capacitor (C185) through a current sink (TR28-B) and maintains a low voltage on the emitter of a transistor (TR28A). With the low voltage maintained at its emitter the transistor remains switched on and charging continues. Loss of the alternating voltage (S) removes the periodic current sink from the capacitor (C185) which charges to a high voltage and by switching off the transistor (TR28A) terminates charging of the phone.
