Abstract: Des systèmes de repérage et/ou de navigation pour véhicules routiers doivent être calés sur des points de localisation, ce qui pose souvent des problèmes, étant donné que le conducteur ne peut pas arrêter son véhicule à ces points-là, par exemple à un croisement, car les dangers représentés par le flux de la circulation seraient trop grands. Il est donc proposé de marquer le point de calage du système de repérage et/ou de navigation à l'aide d'une touche d'indication et de définir plus tard ladite position, par exemple en entrant le nom de la rue, lorsque le véhicule ne se trouve plus à l'endroit dangereux de la circulation.

Abstract: The improvement consists therein that a lubricant film can be measured in the 0.1-20 micron area with a high degree of accuracy. Thereto, between two rotating parts i.e. the shaft (1) and the seal (2), a lubricant film (3) is present whereby in the shaft a sensor (4) with an annular core (5) is applied. A coil (6) is arranged around the core (5). At the outward exten­sion of the core polar pieces (7,8) are located which free ends are directed to the lubricant film to be measured. When an alternating current is supplied to the core (6) a magnetic field is generated which field lines are indicated by dotted lines (10). 
     By adding magnetic particles to the lubricant it will acquire much greater magnetic permeability than air so that the magnetic field will much more be concentrated in the lubricant film.

Abstract: A character generator comprises a phase-coupled clock signal generator which is implemented as a start-stop oscillator (1) to which a line signal is applied. The clock frequency is dependent on an adjusting value (F). For adjusting and monitoring the clock frequency, the clock signal generator is provided with a counter (2). This counter counts the number of clock pulses occurring during a predetermined period and thus supplies a counting value (C). A control circuit (3) compares the counting value (C) with a reference value and adapts the adjusting value (F) in such a way that the oscillator frequency is within a predetermined range. Such a character generator is suitable for On Screen Display applications in a television receiver.

Abstract: There is provided in accordance with the practice of this invention a process for separating albumin from an impure protein fraction containing albumin. Contaminants, in an aqueous solution of the impure protein fraction containing albumin, are precipitated from the solution at a pH of from about 4.5 to about 4.7. Additional contaminants that remain soluble are bound to an anion-exchange resin. After the precipitated and anion-exchange-bound contaminants are removed from the albumin-containing solution, the pH of the solution is adjusted to from about 4.7 to about 6.1, and additional contaminants are precipitated. Further contaminants are then bound to an anion-exchange resin, and these precipitated and anion-exchange-bound contaminants are removed from the albumin-containing solution.

Abstract: A flat stack permeator useful under dialysis, ultrafiltration, reverse osmosis, perstraction, pervaporation, etc. conditions, comprises a multitude of membrane layers (1) alternately separated by feed-retentate spacers (2) and permeate spacers (3). The layers (1) are secured along their edges so as to define separate feed-retentate (A) and permeate (B) zones. The edge gluing is performed so that in any given layer the two parallel edges are secured, while on the layers immediately above and below the edge pairs which are secured are 90 out of register with the previously mentioned pair of secured edges. In that way alternate feed retentate and permeate zones are defined which are perpendicular in flow one to the other. This stack of membrane and spacer layer is fabricated between flat rigid, solid, permeable or non-permeable sheets (7), the membrane sheets immediately adjacent to said solid sheets being edge glued to the sheet along the proper edge defining a feed-retentate or permeate zone as appropriate to form a module. This module is fitted with manifolds to provide a feed-retentate entrance-exit (15) pair and separate permeate exits (16). Alternatively the module can be inserted into an appropriately manifolded pressure vessel (21).

Abstract: Polyimides having a high thermal and oxidative stability are prepared by reacting a mixture of monomers comprising (a) a dialkyl, trialkyl, or tetraalkylester of an aromatic tetracarboxylic acid, (b) an aromatic diamine, and (c) an end cap compound. The ratio of (a), (b), and (c) is chosen so that upon heating the mixtures, low molecular weight prepolymers are formed, the prepolymers having only one end cap radical and being suitable for chain extension and crosslinking to form high molecular weight, thermally stable polyimides. Upon heating, the prepolymers form polyimide resins, which can have T g  in excess of 600°F and superior physical properties.

Abstract: An operational amplifier employs split collector transistors (Q₁, Q₂) for the input differential pair. Through a fractional collector of the input transistors (Q₁, Q₂) a fraction of the currents (1/4) flowing through the two branches of the input differential stage is derived and by means of two complementary mirrors (Q₉ - Q₁₂) having a sufficiently high, combined mirror-ratio, this current, which is proportional to the amplitude of the signal present across the input terminals of the amplifier, is fed as a biasing current (I) to the input node of the output buffer stage (Q x , Q y ) of the amplifier in order to enhance the slew-rate behaviour by ensuring a fast charging of the frequency compensation capacitance (C c ) during a transient condition while maintaining a low power dissipation under small signal steady state conditions.

Abstract: The blood flow in the upper arm is obstructed by a blood flow obstruction bag (220) in a cuff (200) applied to the upper arm. The flow obstruction bag is provided with a front detecting bag (210) and rear one (230) on the up- and down-stream sides thereof respectively, and a front sensor (110) and rear one (120) are provided for detecting pressure in respective detecting bags. Each sensor detects front pulse waves (Wf) and rear ones (Wb) respectively. Standard internal pressure in the cuff is controlled by a pneumatic pump (140) and a leak valve (150) controlled by the CPU (130). With every pulse wave monitored, the internal standard pressure in the cuff can be maintained at systolic phase pressure SP or diastolic phase pressure DP. A propagation speed of the pulse wave passing beneath the cuff whose internal pressure is maintained at the systolic phase pressure SP can be found from the time of delay SPdt of the rear pulse wave from the front pulse wave and is approximate to a blood flow velocity VH when the aorta is at high pressure. A blood flow velocity VL when the aorta is at low pressure is found when dividing the blood flow velocity VH by a given coefficient R. The rear pulse wave obtained when the standard internal pressure is maintained at the diastolic phase pressure DP becomes an approximate aortic wave. On the basis of the waveform of this approximate aortic wave, effective cross-sectional areas SH and SL of the blood flow are found and a blood flow quantity per unit pulse is calculated by multiplying the cross-sectional area by the blood flow velocity.
