Title: Brake valve control system
IPC: B60T8/00
Filed: 1990-05-25
Granted: 1993-04-28
Abstract: The brake valve control system (10) for an aircraft wheel braking system includes primary (20) and backup brake valve control subsystems (22) and a means for isolating and switching between subsystems. Certain portions of the entire braking system are shared, and those portions which are not shared are isolated but interconnected for switching from a primary brake control mode to a backup subsystem upon failure of the primary subsystem. A unique metering spool valve, and the linking of metering spool valves and servocontrol valves with either a tandem selector valve or interlinked primary and secondary selector valves allows for significant reduction in weight and complexity for the backup or override system.

Abstract: An information storage apparatus is disclosed for reading and/or writing information on a rigid disk (10) which includes a non-Newtonian liquid bearing interface (70) between a transducer (21) and a storage medium (10), instead of a conventional air of Newtonian liquid bearing. The non-Newtonian liquid has a composition which exhibits plastic or pseudoplastic flow at high rates of shear. Preferably, the liquid is of the class of compounds whose viscosity shows a negative dependence on shear rate. Thus, as the relative speed of the transducer and the storage medium increases, while their relative spacing decreases, the increasing shear rate to which the liquid bearing is subjected causes the viscosity of the liquid to reduce. Resultantly, very low flying heights can be achieved, which increases the potential storage density on the storage medium, while the reduced drag exerted on the transducer by the lowered viscosity greatly reduces the power required to rotate the medium. <IMAGE>

Abstract: L'invention se rapporte à une structure de disque optique que l'on obtient en collant l'une sur l'autre deux parties de substrats en utilisant un adhésif composé d'une résine thermodurcissable et d'une résine polymérisant sous l'effet des ultraviolets, et à un procédé de production dudit disque optique. Un film céramique est posé sur les périphéries interne et externe de chaque substrat pour transmettre les rayons ultraviolets à l'adhésif, mais ni le film d'enregistrement ni le film réflecteur ne sont posés. Grâce à l'irradiation par les rayons ultraviolets pendant l'étape de collage, la résine polymérisant aux ultraviolets sur la périphérie interne et externe du substrat subit une vulcanisation, de sorte que les substrats sont collés l'un sur l'autre temporairement. On chauffe le disque optique ainsi obtenu pour provoquer la vulcanisation de la résine thermodurcissable. Les deux parties de substrats sont ainsi soudées entièrement l'une contre l'autre. Grâce à l'adhérence temporaire produite par la résine polymérisant aux ultraviolets, il est possible de placer verticalement les substrats pendant l'étape de thermodurcissement sans les déformer et sans que l'adhésif ne coule. La présence des films céramiques sur les périphéries interne et externe des substrats augmente la force adhésive et garantit pendant longtemps une fiabilité accrue.

Abstract: The cryptographic system is comprised of two stations A and B in which a respective string SA and SB of digits is stored. In station A an error-control information string C is generated from string SA and transmitted to station B over an error-free public channel CH1. In station B a particular string D and a decision bit F are generated. String D maximizes a predetermined reliability function of a string combination (SB,C,D). Decision bit F is assigned the value 1 if and only if a maximum value taken on by the reliability function is greater than a predetermined threshold. Decision bit F is transmitted to station A over an error-free public channel CH2. In both stations A and B, the respective strings SA and SB are tagged as accepted when said decision bit F has the value 1. The above sequence is repeated, resulting in a plurality of tagged strings which are concatenated at stations A and B to result in a random cipher key shared by the stations A and B. The predetermined reliability function can be defined as a conditional probability P(S/< ANd >A=D/S/< ANd >B=SB,C/< ANd > =C) that a random variable S/< ANd >A corresponding to string SA is equal to string D, given the conditions that a random variable S/< ANd >B corresponding to string SB is equal to that latter string SB and a random variable C/< ANd > corresponding to the error-control information string C/< ANd > is equal to that latter string C. <IMAGE>

Abstract: A method for the removal and concentration of desired ions from a source solution which may contain larger concentrations of other ions including H<+> comprises bringing the source solution into contact with a compound comprising a polytetraalkylammonium and/or polytrialkylamine containing ligand covalently bonded through an organic spacer silicon grouping to a solid inorganic support. The polytetraalkylammonium and/or polytrialkylamine portion(s) of the compound has an affinity for the desired ions to forma complex thereby removing the desired ions from the source solution. The desired ions are removed from the compound by contacting the compound with a much smaller volume of a receiving solution having a greater affinity for the desired ions than does the polytetraalkylammonium and/or polytrialkylamine ligand portion of the compound. The concentrated ions thus removed may be recovered by known methods. The process is useful in removing desired or unwanted ions from water streams and in the treatment of waste streams. The invention is also drawn to the polytetraalkylammonium and polytrialkylamine containing ligands covalently bonded through a spacer grouping to a hydrophilic inorganic solid support material.

Abstract: The method is of the type in which the metal sheet (W) is manipulated by means of a movable gripping member (G) of a manipulator robot controlled by a programmer (PC) according to a program for positioning successive lines of working of the metal sheet in correspondence with a pair of linear tools (16, 18). The programmer (PC) starts the working program by transporting the metal sheet to the position which corresponds with the first virtual or imaginary working line (Bo). Sensors (S1, S2, Sy) detect the position of the virtual working line and signal to the programmer whether and to what extent the position of this virtual working line differs from the correct position. This is equivalent to the entering in the programmer of a datum relating to the displacement of the engagement point (Co) of the gripping member from its theoretical engagement point (C) on the metal sheet. The programmer moves the gripping member (G) on the basis of the error detected, repositions it relative to the metal sheet (W) at the theoretical engagement point (C).
