IPC: C12N1/26
Filed: 1963-12-30
Abstract: A process which comprises cultivating a yeast, mould or bacteria in the presence of a feedstock which is a petroleum fraction consisting wholly or in part of straight chain hydrocarbons in an aqueous nutrient medium and in the presence of a free oxygen containing gas, the feedstock being present as particles with an average diameter of less than 30 microns. Removal of straight chain hydrocarbons from a petroleum fraction e.g. of waxes from a petroleum gas oil, by using the petroleum fraction in the above process, and recovering from the product of the growth of the micro-organism a petroleum fraction having reduced straight chain hydrocarbon content or being free of same. The pour point of the fraction is thus lowered.

Title: Discolouring and purifying dye-contg. waste waters - by acidifying, reducing with iron, neutralising and clarifying
IPC: C02F1/52
Filed: 1972-12-12
Abstract: Dye-contg. waste waters from textile finishing, paper, photographic and dye mfg. inds., are discoloured and purified by (1) mixing with acid cpds. to set pH to acid range, pref. pH 2-2.5, at room temp. or pH 2.5-3 at 50 degrees C; (2) contacting with finely divided metallic Fe, esp. as shavings or powder, to cause destructive reduction of dyes; (3) neutralising by adding alkali, whereby Fe is pptd. as hydroxide, and (4) clarifying. Acid pH is pref. set with waste acid, e.g. H2SO4, or by mixing with waste waters from acid works. Formation of Fe(OH)3 rather than Fe(OH)2 is helped by adding air and/or H2O2 following reduction. Neutralising takes place with alkalies or by mixing with strongly alkaline waste waters, e.g. from mercerising plant. Fe hydroxide flocculation is favoured by high mol. wt. organic flocculants.

Title: Microwave oven having an infrared sensor with a movable field of view
Inventor: KAWAMURA KAZUHIKO
IPC: F24C7/02
Filed: 2001-02-22
Abstract: A microwave oven is fitted with a movable infrared sensor 7 which is used to detect the presence of food, as well as its temperature, and so control the microwave power supplied to the oven. Two electric motors 23, 25 move the sensor 7 in x- and y-directions so that its field of view moves within the heating chamber of the oven. The course of movement followed by the sensor is advantageous, and quickly includes the food in the field of view. The microwave power can be reduced or turned off until food is detected. In another aspect (fig.19), gearing between the motors and the sensor is disclosed which allows the field of view to be moved with greater accuracy. Also disclosed are in-store demonstration features which allow the sensor 7 to move and the antenna 15 (fig.5) to rotate while the magnetron 12 (fig.5) is off.

Title: Die bond strip
Inventor: MISTRY MAHESHCHANDR
IPC: B23K1/00
Filed: 2001-07-12
Abstract: A titanium alloy strip (50) for use in die-bonding a component (1) to a substrate (3) has a central region (70) which is reduced in cross section compared to the extremities of the strip. The component (1) such as an optoelectronic device is mounted to and bonded by solder to the substrate (3) by passing a current through the strip and heating the central region thereof which melts solder between the component and substrate to form a bond. The heat generated in the narrower central region is greater than that at the extremities of the strip thus providing an enhanced heating and bonding effect. A thermocouple mounted on the central region monitors the strip temperature.

Title: Escrowing with an authority only part of the information required to reconstruct a decryption key
Inventor: UUSITALO IIKKA MIKAEL
IPC: H04L9/08
Filed: 2002-06-27
Abstract: The present invention facilitates the legal interception of an encrypted IP session between two or more terminals 12, 13. A terminal 12 and its GGSN node 5 share a first input key component, however a second input key component is known only to the terminal 12. The terminal generates a key by applying a pseudo-random function (PRF), such as a keyed hash, to the first and second key input components. The key may be directly or indirectly used by the terminal to encrypt and decrypt messages. The node 5 effectively acts as an escrow authority which has only part of the information required to reconstruct the key. However the key may be reconstructed by the node (or an entity authorised to access the node) in a brute force / plain text exhaustive attack, in which all possible values of the second key input component are tried. The terminal may be required to send to the node a clear text and encrypted version of the same message to help in the reconstruction of the key. In one embodiment the first key input component is generated at both the terminal and the node by applying the PRF to a seed value exchanged between the two terminals and to a previously stored secret value shared by the terminal and the node.

Title: Link aggregation
Inventor: WYATT RICHARD M
IPC: H04L12/56
Filed: 2001-01-17
Abstract: In a switch with multiple physical links to a destination, data is forwarded to the destination by distributing received data across the physical links. A flow hash is selected for the received data's data flow dependent on a destination address and source address included in the received data. The flow hash selects one of the physical links to the destination for a data flow but potentially a different physical link for a different data flow, thereby forwarding the received data by distributing the received data across the physical links while maintaining frame ordering within a data flow.
