Title: Process for the preparation of a starch ester
Inventor: LAMMERS GEERT
IPC: C08B31/04
Filed: 1997-12-31
Abstract: Process for the preparation of a starch ester, in particular a starch acetate, wherein a starch-based feedstock is reacted with an organic carboxylic acid anhydride in the presence of a catalyst. The reaction of the starch-based feedstock and the anhydride is performed at an excess pressure of about 0.1 to 50 bar in an essentially anhydrous medium containing 10% by weight of water at the most. As catalyst, sodium acetate, sodium hydroxide or sulphuric acid is used, and as the reaction medium, acetic acid or excess acetanhydride is used. By means of the invention, the duration of the esterification reaction can be significantly shortened, the separation of the product can be facilitated, and the recirculation of the waste solutions can be rendered more efficient.

Title: Filterbank structure and method for filtering and separating an information signal into different bands, particularly for audio signals in hearing aids
Inventor: BRENNAN ROBERT
IPC: H04R25/00
Filed: 1998-04-16
Abstract: A filterbank structure is provided which provides a flexible compromise between the conflicting goals of processing delay, filter sharpness, memory usage and band interaction. The filterbank has an adjustable number of bands and a stacking which provides for a selectable shift of band frequencies to one of two discrete sets of center frequencies. The width of the bands and hence the number of the bands is selected depending upon acceptable delay, memory usage, and processing speed required. The flexibility in terms of stacking of the bands provides twice the number of potential band edge placements, which is advantageous for hearing loss fitting, especially at low frequencies. The same filter coefficients can be used for analysis and synthesis, to reduce memory usage.

Patent AU-7147691-A (AU)
Title: Cooling system for internal combustion engines
Inventor: EVANS JOHN W
IPC: F01P9/00
Filed: 1991-01-10
Abstract: An apparatus for cooling an internal combustion engine has a coolant jacket surrounding the cylinder walls, the combustion chamber domes, and the exhaust runners of the engine. The coolant jacket has formed therein a coolant chamber. A substantially anhydrous, boilable liquid coolant, having a saturation temperature higher than that of water, is pumped through the coolant chamber to cool the metal surfaces of the engine. A radiator is coupled in fluid communication with the coolant chamber to receive coolant flowing therefrom and to reduce the temperature of the coolant by heat exchange therewith. A pump is coupled in fluid communication with the coolant chamber and the radiator to pump the coolant therethrough. The coolant is distributed and pumped at a flow rate so that the coolant vaporized upon contact with the hotter metal surfaces of the engine substantially condenses within the liquid coolant. A vent line is coupled on one end to the coolant chamber and coupled on the other end to an expansion tank. A U-shaped section of the vent line extends above the highest level of coolant in the system. The expansion tank is provided to receive gases, vapor, and/or expanded coolant from the coolant chamber. The expansion tank always holds some coolant to maintain a liquid coolant barrier between the coolant chamber and the ambient atmosphere.

IPC: B65D71/22
Filed: 1994-06-20
Abstract: Means for holding the bottoms of petaloid shaped bottles in place in a wrap-around carrier. Side panel apertures include flaps connected to the side panel by fold lines which are inwardly curved at their upper portions. The lower portions of each pair of flaps extend toward each other so as to engage one or more support feet of the adjacent bottle and be forced out from the side panel thereby.

Patent AU-7464198-A (AU)
Title: A sanitary napkin
Inventor: GUSTAFSSON ANDERS
IPC: A61F13/534
Filed: 1998-05-13
Abstract: An absorbent article with an absorbent body enclosed between inner and outer casing sheets and a stiffening element extending from the rear, through the intermediate, and into the front part of the article. The stiffening element's front and rear parts are broader than its intermediate part and the stiffening element is not wider than 4 cm at its front to intermediate transition region. Side flaps are formed by at least some parts of the remainder of the article which extend laterally beyond the stiffening element, so that the distance between side-edges of the stiffening element and an edge of the side flap varies within the region. The stretch resistance of the side flaps is greater than the stiffening element's longitudinal bending resistance, so inward pressing of the side flaps causes the stiffening element to curve longitudinally, to obtain an upwardly concave shape adapted to the shape of a wearer's body.
