Abstract: La asignación de una dirección IP a una información de sesión para usarla como identificador de una estación móvil, facilita una arquitectura distribuida para el procesamiento de las comunicaciones IP en coordinación con un sistema de comunicación inalámbrico. La dirección IP de la información de la sesión identifica una localización de almacenaje para la información de la sesión que corresponde a un AT dado. El AT eficientemente lleva un puntero para la información de la sesión, donde un punto de acceso puede tener acceso a la información de la sesión directamente. Esto evita la necesidad de almacenar la información de mapeo para cada AT y la localización asociada de la información de la sesión. Adicionalmente, el uso de una dirección IP identificando el propietario de la sesión como un identificador de la estación móvil evita demoras incurridas por tal mapeo. La dirección IP de la información de la sesión se puede comprimir para utilizar un valor localmente único. La versión comprimida conserva espacio de bit, y reduce la complejidad de procesamiento en la re-localización de un punto de acceso próximo.

Abstract: 1,229,257. Grinding machine. HUTA BAILDON. 19 Nov., 1968, No. 54818/68. Heading B3D. A grinder for segment rolls 12 intended for rolling grooves of twist drills comprises a table 1, an abrasive wheel 3 and means for supporting the wheel on the table and applying it against a workpiece, a headstock 2 supported on the table by a pivot connection 4, a connecting-rod 6 including a telescopic arm 7 connected to the table and coupled with the drive spindle of the headstock, and a spring 5 connected between the table and the headstock. The arrangement is such that the drive spindle of the headstock, the rod 6 and the spring 5 co-operate to impart to a workpiece carried by the drive spindle of the headstock and contacted by the wheel 3 on a prolongation of the axis of the connection 4, a rotary movement about the axis of the drive spindle, and an oscillatory movement about the axis of the connection 4, the oscillatory movement being limited by a fully retracted position of the arm 7 on the one hand and contact of the headstock with a stop 11 provided on the table, on the other. The arm 7 as described is connected to the headstock drive spindle by a grip 8 and crank 9. The length of the crank 9 and of the arm 7 and the position of the stop 11 can be varied to cater for different rolls 12.

Abstract: 1,230,222. Testing transfer characteristics. WANDEL U. GOLTERMANN. Sept. 10. 1968, [Sept. 13, 1967], No.42982/68. Heading G1U. Also in Division H3-5] In a decade sweep frequency generator comprising a standard frequency generator connected to decade stages which are adjustable by a reversible counter to sweep the frequency, the output from the counter is compared with a reference count in a comparator which produces a signal when the counter output coincides with the reference count. The signal may be arranged to: - (a) stop the sweep (b) reset the counter to start a new sweep or (c) reverse the count direction to give a reverse sweep. One or more generators may be used in measuring the transfer characteristics of an element in a transmission path. In one such arrangement, Fig. 3 a signal from a source 66 is mixed with a signal from sweep generator 55 to produce a sweep signal is a suitable range for the input to unit 57 to be tested. The output signal from unit 57 is then mixed with that from a second sweep generator 56 to produce an output signal which is fed to an indicator. The two sweep generators are synchronized by a connection 62 which may include a divider 63 when the two sweep bands have a different mean frequency. If a synchronizing connection is not possible, the second generator may be synchronized by the signal applied to the indicator, Fig.4 4 (not shown). Where the input and output frequencies of unit 57 are the same, one sweep generator may be connected to both mixers, Fig. 2 (not shown).

Abstract: 1,230,393. Photographic supersensitized silver halide emulsions. ILFORD Ltd. Sept. 16, 1969 [July 3, 1968], No. 31706/68. Heading G2C. A photographic silver halide emulsion is supersensitized with a dye of the formula: - where R 1  is alkyl of 1-4C or sulphoalkyl; R 2  is alkyl of 1-4C, aryl, aralkyl or alkoxy; R 7  is -OR 3  or -NR 9 R 10  where R 3 , R 9  and R 10  and each H or alkyl of 1-4C; R 8  is -SO 3 H or -COOH; Y is S or Se; Z is straight or branched alkylene of 1-6C and X is an anion, or the corresponding zwitter ion formed by eliminating HX, together with a dye of the formula: - where R 4  is alkyl of 1-4C; R 5  is halogen, methyl, amino or cyano; Z is as above and M is a cation or a hydrogen ion. A styryl base may also be present of the formula: - where A completes a thiazole ring and R 11  and R 12  are each alkyl of 1-4C. The dyes sensitize to green.

Abstract: 1,230,935. Windscreen wipers. ANDERSON CO. 11 April, 1969 [25 April, 1968], No. 18830/69. Heading A4F. In a windscreen wiper assembly including an arm 10 pivoted to a mounting head 36, a link 82 interconnects the head 36 and springs 66a (Fig. 5, not shown) and 66b, for biasing the arm towards the windscreen, and is connected to the springs by a member 92 slidable on a guiding surface on a bracket 96 secured to the arm 10. Thus as the springs 66a, 66b flex during a wiping operation the sliding movement of the member 92, which may be of nylon impregnated with molydenum disulphide, is effective to maintain the wiping pressure substantially constant. The wiper blade 16 (Fig. 1, not shown) is pivotally connected to the arm 10 by a crank 52 (Fig. 3, not shown) forming ,part of a known drag link mechanism for swinging the blade relatively to the arm during the wiping operation.
