Abstract: L'invention concerne un ensemble inhibiteur de détergents qui exerce une influence sur le propriétés viscosimétriques de lubrifiants SAE 5W qui contiennent moins 5 % en masse d'une substance de base non classique, et utilisant une substance de base qui a un nombre neutre moyen de substance de base supérieur ou égal à 105, une volatilité Noack calibrée inférieure ou égale à 22 % en poids de perte, et une viscosité cinématique inférieure à 12,5 cSt à 1000  DEG C (100 kV, mesurée par ASTM D445). En particulier, des sels de calcium neutres et hyperbasiques d'acides organiques accroissent la viscosité d'un cisaillement élevé à basse température, mesurée dans le simulateur de démarrage à froid (CCS) (ASTM D5293). Ces sels, très utilisés pour leurs propriétés détergentes et de neutralisation d'acides, ne devraient pas être employés, sinon en quantités inférieures ou égales à 0,0007 moles de sel de calcium organique pour 100 grammes de lubrifiant. Lorsque le diesel est employé, par exemple pour lubrifier un moteur diesel de voiture particulière, un sel de calcium d'un acide organique peut être nécessaire pour réguler les résidus du piston. Dans ce cas, le niveau de sel calcium devrait être compris entre 0,0004 et 0,0007 moles pour 100 grammes de lubrifiant.

Abstract: An apparatus for separating relatively light fractions from relatively dense fractions in a pulp suspension.  The apparatus has a tubular housing of circular cross section defining a separation chamber extending longitudinally from an inlet end to an outlet end, with an inlet at the inlet end for tangentially introducing a flow of the pulp suspension into the housing for vortical flow along the length of the separation chamber towards the outlet.  The vortical flow effects a separation of the relatively light fraction from the relatively dense fraction.  The housing has at least two outlets at the outlet end, one outlet being positioned to accommodate an exiting flow of the relatively light fraction and the other outlet being positioned to accommodate an exiting flow of the relatively dense fraction. The diameter of the separation chamber at an intermediate region along its length is enlarged in comparison to its diameter at the inlet and outlet ends.

Abstract: A method of preparing stackable block structures from raw concrete mixes and block structures prepared in accordance with the method, wherein the process utilizes a mold box configured to form the block on its side surface. The mold box is arranged to travel along the surface of a moving conveyor belt, with the box having an open top, an open bottom, and lateral side panels supported on the conveyor belt surface, and with the panels having core bar receiving openings formed therein. The core bars are introduced and removed from the mold box along an axis which is parallel to the surface of the core bars and to the motion axis of the conveyor belt, and with the core bars configuring one of the two opposed side surfaces of the stackable block. A reciprocating top shoe arranged for reciprocatory up and down motion engages and configures the top surface of the raw concrete mix held within the walls of the mold box.

Abstract: In this method for cementing an implant into bone by means of an autopolymerising two-component bone cement the implant, in particular the stem of a hip prosthesis is preheated above room temperature prior to its cementing into bone, preferably to at least 43° C. By this method the stem-cement interface is warmer than the bone-cement interface and consequently a stiff cement shell will form first around the stem and the cement will shrink towards the stem and away from the bone. The resulting reduction of porosity at the stem-cement interface improves significantly the fatigue life of the system.

Abstract: An electric vehicle is controlled to conform its operation to that of a conventional internal-combustion-engine powered vehicle. In some embodiments, the charging of the batteries by the auxiliary source of electricity and from dynamic braking is ramped in magnitude when the batteries lie in a state of charge between partial charge and full charge, with the magnitude of the charging being related to the relative state of charge of the battery. The deficiency between traction motor demand and the energy available from the auxiliary electrical source is provided from the batteries in an amount which depends upon the state of the batteries, so that the full amount of the deficiency is provided when the batteries are near full charge, and little or no energy is provided by the batteries when they are near a discharged condition. At charge states of the batteries between near-full-charge and near-full-discharge, the batteries supply an amount of energy which depends monotonically upon the charge state. Charging of the batteries from the auxiliary source is reduced during dynamic braking when the batteries are near full charge. Control of the amount of energy returned during dynamic braking may be performed by control of the transducing efficiency of the traction motor operated as a generator.

Abstract: To compensate for the poor signal-to-noise ratio when transforming a patient tracheal sound signal into a respiration flow signal, the transformed signal is used when the sound signal is above a threshold, and interpolated values are used when the sound signal is below the threshold. A volume of breath signal is reliably obtained. Respiration start/stop is detected either by analyzing the sound signal or by physical measurement of the patient. A wearable device incorporating the sound signal processing method can provide an immediate indication or alarm when the volume of breath signal indicates a condition requiring medical attention.

Title: Method and apparatus for enhanced call setup
Inventor: XU JIM
IPC: H04W76/02
Filed: 1998-08-14
Granted: 2004-05-25
Abstract: A method is illustrated for reducing the call setup time of high priority calls such as voice or high speed user generated data without unduly wasting RF frequency resources on non priority calls such as short message calls. This is accomplished by ascertaining the call priority at the base station controller (BSC) level in a GSM system soon after call initiation and immediately changing the channel assignment for use by the remaining signalling type messages to a different operational speed where appropriate. The concept is further extended by supplying the call priority data to a called party's BSC such that all signalling messages after initial contact can be at the operational speed appropriate to the priority of the call.
