Patent GB-2294138-A (GB)
Title: Data processing circuits and interfaces
Inventor: BARLOW STEPHEN JOHN
IPC: G06F9/302
Filed: 1995-09-25
Abstract: An integrated circuit contains a microprocessor core, program memory and separate data storage, together with analogue and digital signal processing circuitry. The ALU is 16 bits wide, but a 32-bit shift unit is provided, using a pair of 16-bit registers. The processor has a fixed length instruction format, with an instruction set including multiply and divide operations which use the shift unit over several cycles. No interrupts are provided. External pins of the integrated circuit allow for single stepping and other debug operations, and a serial interface (SIF) which allows external communication of test data or working data as necessary. The serial interface has four wires (SER_IN, SER_OUT, SER-CLK, SER_LOADB), allowing handshaking with a master apparatus, and allowing direct access to the memory space of the processor core, without specific program control. Within each processor cycle, the processor circuitry is divided into plural stages, and latches are interposed between the stages to minimise power consumption. <IMAGE>

Title: Plasticised PVC compositions
Inventor: DELLAR RICHARD JOHN
IPC: H01B7/295
Filed: 1996-06-21
Abstract: Esters of fatty acids having the formula RCOOR 1 wherein the groups R and R 1 which may be the same or different represent alkyl or alkenyl groups comprising from 6 to 24 carbon atoms have been discovered to be used as lubricants in PVC compositions which comprise a phosphate ester as a plasticiser or flame retardant because their use reduces the evolution of unpleasant odours during manufacture of the compositions and in applications such as extrusion. The novel PVC compositions find particular value in coating of wire and cable where they reduce odour and may enable the use of a composition which does not contain any heavy metals. The preferred ester is stearyl stearate.
Patent GB-2315491-A (GB)
Title: Adhesive composition
Inventor: VOSTERS P J C
IPC: C09J171/02
Filed: 1996-07-18
Abstract: An adhesive or sealant composition suitable for a variety of industrial applications or as a motor vehicle windscreen adhesive, comprises a cross-linkable polymer and a cross-linking catalyst for the polymer and is characterised in that the polymer is a moisture cross-linkable polymer, suitably a silyl-modified polyether or polyester, and in that the composition comprises a water-scavenger capable of preventing or delaying the cross-linking of the polymer, an adhesion promoter and a rheology controller. Other materials such as fillers or pigments may also be present. To isolate the composition from ambient moisture which might overcome the effect of the water scavanger and cause premature cross-linking the composition is preferably contained for storage in a water-impermeable container. The water-scavenger may be an alkoxy-or oximino-silane; the adhesion promoter, amino-, mercapto- or epoxy silane or a siloxane; the rheology controller, a polyamide wax.

Title: Ferroelectric liquid crystal device alignment
Inventor: BRYAN-BROWN GUY PETER
IPC: G02F1/141
Filed: 1995-01-30
Abstract: A ferroelectric liquid crystal device comprises a layer of a ferroelectric liquid crystal material contained between two cell walls carrying electrode structures and a surface alignment treatment. The surface alignment is provided by a profiled surface, e.g. a grating, on at least one cell wall. The grating may be a monograting or a bigrating, with a symmetric or asymmetric profile. Such a profiling enables surface tilt and alignment anchoring energy to be independently arranged to suit liquid crystal material and device type to give a required molecular arrangement and low device defect. The grating may be provided by interferography, photolithography, embossing, ruling, or carrier layer transfer. Alignment directions on the cell walls may be parallel or non parallel. The surface tilt on both cell walls may be the same or different values. The cell walls may be relatively rigid, e.g. glass slides, or flexible e.g. thin plastic which may have its inner face embossed to provide one or both a grating and a set of spacer pillars.

Title: Synthesis of 1-methyl-7-(1rs,2r,3s,4s,5s)-2,3,4,5,6-pentabenzyloxy-1-hydroxyhexyl-3,5,8-trihydroxyanthra-9,10-quinone-2-carboxylic acid and intermediates

IPC: C07C66/02
Filed: 1997-12-12
Abstract: 1-Methyl-7-(1RS,2R,3S,4S,5S)-2,3,4,5,6-pentabenyloxy-1-hydroxyhexyl-3, 5,8-trihydroxyanthra-9,10-quin one-2-carboxylic acid (5, R = H) an intermediate for the synthesis of 6-deoxycarminic acid (I, R = H) is synthesized by the reaction of methyl leuco-6-deoxykermesate (4, R = Me) with 2,3,5,5,6-penta-O- benzyl-D-glucose under aqueous alkaline aldol reaction conditions. Alkyl 6-deoxykermesates (3, R = alkyl) are converted chemically to alkyl leuco-6-deoxykermesates (4, R = alkyl) and benzyl 6-deoxykermesate (3. R = benzyl) is hydrogenolysed catalytically to leuco-6-kermesic acid (4, R = H). Although (4, R = Me) under the prolonged aldol reaction non-aqueous conditions in ethanol containing piperidinium acetate with paraformaldehyde gives methyl 3,5,9-trihydroxy-1,6-dimethylanthra-9,10-quinone-2-carboxylate, (4, R = Me) in aqueous methanolic alkaline reaction conditions gives the 1,7-dimethyl isomeric compound. Under mild conditions the 7-α-hydroxyalkyl compound is formed as a precursor of the 7-alkyl compound and thus with these mild aqueous alkaline reaction conditions the synthesis of (5, R = H) from (4, R = Me) is effected, the methyl group being hydrolyzed in the process.

Title: Control of the distribution of torque to the output shafts of differential gearing
Inventor: KUROKI TADASHI
IPC: F16H48/32
Filed: 1998-01-16
Abstract: In a vehicle differential mechanism having an input shaft 403 and a respective clutch 211 in the drive to each output shaft 203, 205 to control the distribution of torque from the input shaft to the output shafts and between the two output shafts, the clutches are operated alternately, at a predetermined rate, to control the behaviour of the vehicle. The period of the alternation is less than the period of vibration of a yaw motion of the vehicle. The control of the clutches is also dependant on accelerator opening, steering wheel angle, vehicle speed, wheel speed and longitudinal and lateral accelerations. The differential may include change speed gearing 213 in the connection to each output shaft and one clutch may act directly between the output shafts (Fig. 7).
