Title: Variable-key cryptography system
Inventor: SHAW WILLIAM YIN
IPC: H04L9/18
Filed: 1995-03-10
Abstract: Binary data is encrypted or decrypted using a final key. The final key is formed by manipulating one or more user keys and a base key, and combining the manipulated keys using an exclusive-OR operation. The data to be encrypted or decrypted are combined with the final key using a circular exclusive-OR operation. The user and base keys are binary sequences having any number of bits. The user key may be input to the present invention directly in binary form or in any other suitable form that the present invention can interpret as a binary sequence, such as a string of ASCII-encoded alphanumeric characters. Manipulating the user key includes the steps of shuffling or permuting segments of the user key, such as bytes, circularly shifting the permuted user key by a number of bit positions, and filling a location with one or more copies of the permuted and shifted key such that the result has a length equal to that of the base key. The ordering of the segments of the user key in the permutation step and the number of bit positions by which the user key is shifted in the shifting step are determined in response to the value and position of the segments of the user key itself. Manipulating the base key includes the step of circularly shifting the base key by a number of bit positions that is determined in response to the value and position of segments of the user key.

Abstract: A sealing assembly comprises a first moulded graphite ring 3 of triangular cross-section, one side of which is in use perpendicular to the longitudinal axis of a rotatable and/or slidable shaft 1 the surface of which is to be sealed in an axial direction against fluid leakage therealong. A second side is in use disposed parallel to said shaft to engage the inner wall of a housing surrounding said shaft. A second moulded graphite ring 11 is also of triangular cross-section and of similar dimensions to the first moulded ring. The second ring is installed in inverted relation to the first ring to define therebetween an axially extending void around said shaft. A third moulded graphite ring has a triangular cross-section and is installed between said first and second rings to fill said void prior to the application of axial pressure to said rings to develop a sealing force between the inner wall of said housing and said shaft. The rings are moulded from square or rectangular rings made by winding graphite tape. Preferably the tape is exfoliated graphite having a density of 1.0g/cm 3 . After moulding the density is greater than 1.3g/cm 3 . Header rings 10 are of plaited carbon fibre yarns of 6 micron diameter impregnated with a minor quantity of ptfe and/or a high viscosity lubricant. The carbon fibres have a low sodium content.

Patent GB-2312549-A (GB)
Title: Optical pickup device
Inventor: CHOI YANG-OH
IPC: G11B7/139
Filed: 1997-04-25
Abstract: A laser beam generated from a laser light source (130) is reflected by a beam splitter (160) to proceed towards an optical disc (180). The beam is focused onto the optical disc by way of a selective light-transmitting part (150) installed in front of the optical disc (180) and an objective lens (170). The beam is totally transmitted through an inner circular portion (151) of the selective light-transmitting part (150) and half transmitted through a peripheral portion (152) of the selective light-transmitting part (151). The beam transmitted through the inner circular portion (151) forms the larger beam spot on the disc, whilst the beam transmitted through the peripheral portion (152) forms a smaller beam spot. Spherical aberrations that might occur due to changes in thickness of the optical disc are minimized by using the beam with smaller numerical aperture which has been transmitted through the inner circular portion of the selective light-transmitting part.

Patent GB-2330669-A (GB)
Title: User interface for data processing apparatus
Inventor: EASTTY PETER CHARLES
IPC: G06F3/0488
Filed: 1997-10-24
Abstract: Data processing apparatus, in particular an audio mixing console, has a fader panel (30, fig. 1) comprising an array of touch-sensitive controls 350. Each control corresponds to a channel strip (300, fig. 4) on a display screen (10, fig. 1), which shows the processing controls and devices for that channel, and the current control settings (fig. 6). Proximity sensing apparatus associated with the controls detects whether a user's hand is within a predetermined distance of one or more of the controls, and the fader display on the corresponding channel strip is coloured in a contrasting colour, 410, getting more saturated as the user's hand approaches the fader touch-sensor 350. A further contrasting colour is displayed, 400, when the touch-sensor is touched, and so open to adjustment. Thus the user can track his hands across the fader panel (30, fig 1) from the display screen (10, fig. 1) rather than having to look at the fader panel itself.
Patent GB-2321355-A (GB)
Title: Lidar for range and speed measurement
Inventor: STREICHER JUERGEN
IPC: G01S17/58
Filed: 1998-01-15
Abstract: A pulsed laser performs Doppler analysis of each range cell to determine the target's range and radial velocity by correlating successive returns from a cell to determine their relative phase and hence the Doppler frequency shift. This is done by summing the complex conjugate of one return multiplied by the other. Values of the multiplicand outside a range preset in dependence on the expected target velocity are discounted. This eliminates problems arising from the discontinuity of the arctan squared function that is used around +/- 180 degrees.

Title: Demodulator alignment correction in tuners
Inventor: COWLEY NICHOLAS PAUL
IPC: H04H20/00
Filed: 1998-12-09
Abstract: A tuner demodulator alignment system adjusts the centre-frequency of the PLL-demodulator VCO to achieve alignment with the centre-frequency of the IF entering the demodulator by: injecting into the PLL stage a signal having a frequency equal to the nominal centre-frequency of the IF; electronically adjusting, e.g. by means of a digital-to-analogue converter (DAC) controlled from a tuner micro-controller, the VCO frequency until this frequency is aligned with the injection frequency, then removing the injection signal and reverting to normal tuner operation. Alignment with the injection frequency may be signalled by a change in logical state of an AFC flag signal provided by the PLL stage and employed during normal use of the tuner. This may be repeated on an ad-hoc basis, e.g. whenever channels are changed by the user, or more periodically as controlled by the tuner software, or may be performed on a one-off basis only on the production bench.

Title: Reduced viscosity gelatin mixture used in a process for making a direct dispersion of a photographically useful material
Inventor: CONNELLY RICHARD WAYNE
IPC: G03C1/047
Filed: 1998-12-17
Abstract: A process for making a direct dispersion of a photographically useful material is disclosed and comprises: mixing (i) an aqueous phase comprising a gelatin solution and (ii) a liquid organic phase comprising a photographically useful material under conditions of high shear or turbulence to form a fine dispersion of the organic phase having an average particle size of less than 0.5 micron dispersed in the aqueous phase; wherein the gelatin solution comprises a mixture of a first gelatin having an isoelectric point pH of less than or equal to 5.2 and a second gelatin having an isoelectric point pH of greater than or equal to 6.0. In accordance with the invention, the use of blends of a first gelatin having an pl of less than or equal to 5.2, such as a conventional lime processed gelatin, and a second gelatin having an pl of greater than or equal to 6.0, such as an acid processed gelatin, in a direct photographic dispersion yields a substantial reduction in viscosity in comparison to the use of the first gelatin alone, which reduction is greater than would be expected by just using blends of the first gelatin with another relatively low pl gelatin having an equivalent inherent viscosity as the second gelatin. In accordance with preferred embodiments of the invention, relatively low levels of APO gelatin may be used partially replacing LPO gelatin in a dispersion formulation to obtain significant viscosity reduction while minimizing adverse effects which may be associated with the use of higher levels of acid processed gelatin.
