Patent GB-2349213-A (GB)
Title: Determining the positional accuracy of multi-colour printing heads
Inventor: SIEVERT OTTO K
IPC: B41J2/21
Filed: 1997-03-17
Abstract: To determine the positional deviation of an automatic marking implement from a nominal position, calibration patterns 402, 404, 406, 408 are formed during movement of the implement along only one dimension (Y) of a printing medium having orthogonal dimensions X and Y. A sensor (figs. 1, 200) automatically scans the patterns along one (ideally the same) dimension (Y). Deviations along the scanning dimension are determined from scanning indicia 406 orthogonal to that direction; composite information about deviations in both dimensions (X, Y) is determined from scanning diagonal indicia 408, and deviations in the orthogonal direction (X) are calculated by combining these two values. There is no necessity of either forming or sensing any pattern that is extended (by more than one marking-implement swath) in two different directions; thus the medium does not need to be advanced in the X direction. The system can determine deviations from nominal offsets between plural marking implements, such as thermal-inkjet pens holding ink of different colours in a computer-controlled printer.

Title: Legal interception of encrypted IP traffic
Inventor: UUSITALO IIKKA MIKAEL
IPC: H04L12/56
Filed: 2001-12-07
Abstract: A method of facilitating the legal interception of an IP session between two or more terminals I,R, wherein said session uses encryption to secure traffic. The method comprises storing a key k allocated to one of said terminals I at the terminal and at a node TTF within a network through which said session is conducted. Prior to the creation of said session, a seed value 'Nonce' is exchanged between the terminal I at which the key is stored and said node TTF and a security function PRF( ) is applied to the key and the seed value at both the terminal I and the node TTF to generate a pre-master key k_m. The pre-master key also becomes known to the other terminal R involved in the IP session. The pre-master key is used, directly or indirectly, to encrypt and decrypt traffic associated with said IP session. The traffic may be intercepted using the pre-master key available at the node TTF. The security function is preferably a pseudo-random function. Terminal R may provide a second seed value and the security function may be applied to both seed values.

Title: Process for the removal of blowing agents / ozone depleting substances from rigid foam in refrigeration equipment
Inventor: CLARK ANTHONY JAMES
IPC: B29B17/02
Filed: 2002-01-04
Abstract: A process for the removal of ozone depleting substances (ODS) from foam insulating material of refrigerator equipment carcasses 4 involves (after degassing and removing the compressor unit) removing the top and bottom of the carcass, placing the remaining shell 4 within an hermetically sealed enclosure 14 (seals 15) and grinding down the foam insulant with a series of rotating augers 7 and brushes (positioned at the end of flexible driving shafts 8 and driven by gear train 10, 11) so as to produce a concentrated mixture of ODS vapours which may be subsequently collected. The concentration of the vapours is increased by filling any void spaces within the carcass with bulk material or an inflatable air bag 18. This also serves to facilitate the removal of any vapours which are released from the foam (and which are additionally recycled to the enclosure so as to minimise loss to the atmosphere). Foam residue falls in to hopper mill 9, underneath which outlet 13 (which may carry mill driveshaft 12) is positioned. A relationship between clamps 16, flexible bellows 6 and a switch within lid 1 allows the sideways oscillation of the carcass so as to ensure the removal of all foam. Augers may be arranged in an offset double row and may also have a quick-release nature so as to be removed and replaced with augers of different sizes. An interlocking system 3 prevents enclosure lid 1 being open until the ODS vapour concentrations reach a pre-determined level.

Title: Optical device for converting the readings of a meter with rotary indicator to an electrical output
Inventor: ULLATHORNE DAVID PAUL
IPC: G01D4/00
Filed: 2002-05-29
Abstract: The apparatus (30) has a movable member e.g. a rotary indicator (10) that is arranged to move through a regular path in dependence on an amount of a commodity measured by the meter. A light source (31) directs a beam towards a portion of the movable member which has a different reflectivity from a portion of its regular path (20). A photodetector (32) receives the reflected beam from the portion of the path. A control means (33) samples electrical output from the photodetector whilst the light source is not emitting, and samples the electrical output whilst the light is emitting to produce an output representative of the difference between the two sampled electrical outputs. It repeats the two samplings and produces an electrical signal at appropriate intervals. The output signal may be a pulse, and the control may change the signal to indicate the passage of the rotary indicator from a portion of its path. Thus the effect of the ambient light is eliminated, and a single sensor is used.
