Title: Method for producing anion exchange fibres
Inventor: ZVEREV MIKHAIL PETROVICH
IPC: D06M11/63
Filed: 1986-09-04
Abstract: The method for producing polyacrylonitrile based anion exchange fibres comprises the forming of fibres, treating them either with an aqueous solution of hydrazine hydrate then an aqueous solution of sodium hydrate until 5-20% of nitrile groups are hydrolyzed into carboxyl groups, or treating the fibres with an aqueous solution of hydroxyalamine until 3-10% of nitrile groups are transformed into hydroxamic groups. The fibres containing 3-20 mass % carboxyl or hydroxyamic groups are subjected to the effect of aminating agents, then washed and dried.

Title: Tape recorder
Inventor: ARATA TADAO
IPC: G11B15/10
Filed: 1987-06-18
Abstract: A tape recorder of reduced size and reduced numbed of operation buttons, comprises a head plate 3 which when moved for the first time beyond an actuated position, is arrested at the actuated position by an arresting member 26, movement of head plate 3 moving switch operating member 18 to turn on motor switch 25, and tape end detecting member 13 operating a releasing member 38 which enters a range of rotation of a rotary member 2 so as to be later engaged and moved thereby to release the head plate 3 from the arresting member 26. Consequently, head plate 3 returns to its home position as does switch operating member 18 to cause switch 25 to turn off. On the other hand, when head plate 3 is moved for the second time beyond the actuated position before arrival of a tape end, it is released from the arresting member 26 and returns to its home position. The arresting member is detailed (eg Figs 3,4). Pin 44 may be on another rotary member such as a capstan flywheel. <IMAGE>

Title: Continuous extrusion of tubes
Inventor: FAIREY NORMAN REGINALD
IPC: B21C25/00
Filed: 1988-09-01
Abstract: In continuous extrusion by the Conform process, tubes are formed (especially from relatively hard metals such as copper) using tooling located in the wheel groove. An abutment 1 obstructs the extrusion passageway at its downstream end (but preferably does not block it completely) to establish an upset region from which the metal passes through a die orifice 10, and a cantilevered projection extends from the abutment to enter the die orifice where it acts as a mandrel to define the bore of the tubular product 8. <IMAGE>

Title: Linearisation by signal cancellation to remove unwanted signals in a transmission
Inventor: SNOW JOHN RICHARD COBDEN
IPC: H03F1/32
Filed: 1989-03-03
Abstract: Amplifiers (or other non-linear devices) are linearised by cancelling out the unwanted distortion products. This is achieved by measuring the amplitudes and phases of these products and creating cancellation signal of equal amplitude and opposite phase. Use is made of the fast Fourier transform in both forward and inverse modes. The technique operates over wide bandwidths and cancellation of up to 40 dB is realised. Processing unit 1 stores an input signal in the frequency domain. After inverse Fourier transformation 2 into the time domain and conversion 3 to analogue the signal is subjected to the mono linear amplifiers. The amplifier output is redigitised 6, subjected to Fourier transformation 7; the process unit measures any unwanted frequency components (distortion) and adds a cancellation signal to the input signal prior to amplification, after which an output signal is produced. <IMAGE>

Title: Pneumatic tyre and wheel assembly.
Inventor: HOLROYD ERIC
IPC: B60C5/00
Filed: 1992-02-20
Abstract: A pneumatic tyre and wheel assembly (10) particularly suitable for heavy duty use to replace a side-by-side pair of coaxial tyres comprises a flexible reinforced partition wall (17) which extends between the tyre tread region (15) and a third bead region (16) disposed between the bead regions (13) of the sidewalls (14). The third bead region (16) is dimensioned to seal against a wheel rim (11) such that the resulting tyre and wheel assembly (10) may comprise two independently pressurisable chambers (25, 26). Forces tending to deform the tyre either radially or transversely will place an upper part of the partition wall (17) in tension, tending to maintain the shape of the tyre. By this arrangement the need for heavy, stiff sidewalls (14) is avoided.

Title: Television standards converter
Inventor: BAE JUM HAN
IPC: H04N7/01
Filed: 1992-12-31
Abstract: A television standards converter includes a two-field video memory 210 capable of storing 525 lines of video signal for field interpolation, and separate luminance and chrominance line memories 190, 200 for line interpolation. For conversion from a standard having 625 lines (eg PAL, SECAM) to one having 525 lines (eg NTSC) line interpolation is effected first before field interpolation, whilst for conversion from a standard having 525 lines to one having 625 lines field interpolation is effected first. This allows the use of a video memory with a reduced amount of storage. The standards between which conversion takes place may be selected. <IMAGE>

IPC: C07C29/09
Abstract: 923,131. Alcohols. CONTINENTAL OIL CO. Dec. 8, 1960 [Feb. 15, 1960], No. 42256/60. Class 2(3). Primary and secondary alcohols are obtained by reacting at a temperature of -10 to 175‹C. an epoxy compound of formula n which R 1  and R 2  are both hydrogen atoms or both saturated C 1 -C 10  alkyl radicals, with an organo-aluminium compound having the formula AlR<SP>1</SP>R<SP>11</SP>R<SP>111</SP>, in which R<SP>1</SP> is an alkyl group and R<SP>11</SP> and R<SP>111</SP> are hydrogen or halogen atoms or alkyl radicals, or a triaryl aluminium compound, and hydrolysing the reaction product. Suitable epoxy compounds are, for example, ethylene oxide, 2,3-epoxybutane, 2,3-epoxypentane, 2,3-epoxyhexane, 3,4-epoxyhexane, 5,6-epoxydecane, 3,4-epoxydecane, 10,11-epoxyeicosane, 8,9-epoxyoctadecane, 2,3-epoxydodecane and 11,12-epoxydocosane. Preferably the first step of the process is carried out in the presence of a solvent, for example, a saturated aliphatic or aromatic hydrocarbon. In the example triethylaluminium and ethylene oxide are reacted to give an aluminium alcoholate product which on hydrolysis gives a mixture of n-butyl alcohol and sec-butyl alcohol.

Title: Motion compensated video signal processing; motion/no motion flag
Inventor: DAVID MORGAN WILLIAM AMOS
IPC: H04N5/44
Filed: 1993-04-08
Abstract: A "motion flag", indicating whether an output pixel represents a moving or a stationary part of the current output image, is generated by detecting whether the degree of correlation between test blocks of the two input fields (from which that output image is to be interpolated) pointed to by a zero motion vector exceeds a threshold.   The motion flag may be used in a standards converter (fig. 1) to control the selection of interpolation coefficients (fig. 9). <IMAGE>
