Abstract: ABSTRACT OF THE DISCLOSURE     A vortex-type flowmeter having a flow tube forming a conduit for the fluid to be metered and an obstacle assembly mounted therein capable of generating fluidic oscillations.   These oscillations cause a deflectable section of the assembly which is cantilevered by a flexible beam from a fixed section mounted across the tube to vibrate at a corresponding fre-quency proportional to flow rate.  These vibrations are mechan-ically transmitted to a coupling point outside the flow tube, whereby the flow rate may be read by means of an external force sensor engaging the coupling point.  Vibration transmission is effected by a rod secured at one end to the deflectable section and passing through a bore in the flexible beam to join a probe which extends at right angles thereto.  The probe is disposed within a bore in the fixed section and projects through an opening in the flow tube wall to terminate in the outside coupling point.  The probe is held by a flexible diaphragm covering the flow tube opening and acting as a fulcrum, the outside portion of the probe being short in length relative to the inside portion, whereby the resultant lever affords mechan-ical advantage to amplify the force applied by the coupling point to the force sensor.

Abstract: Abstract of the Disclosure A gas-contaminant separator for separating gas-contaminant mixtures created by an internal combustion engine into gas and contaminants includes inlet ports for inlet of the mixtures at the bottom of each leg of an inverted V-shaped housing and an outlet port at the top vertex for exhaust of the gas.  The total Cross-sectional area of the inlet ports provide inlet mixture flow velocities below two meters per second.  In the separator, first baffles are provided proximate the inlet ports to direct the mixtures towards and into a first contact with each other.          Second baffles, disposed above the volume where the mixtures first contact cooperate with the housing to define a primary sedimentary precipitation zone and cause first retroversions of the mixtures towards and across the tops of the first baffles with the bulk of the contaminants being centrifugally precipitated by the first retroversions into the primary sedimentary precipitation zone for sedimentary precipitation to the bottoms of the housing.  The sides of the housing cooperate with third baffles to cause second retro-versions of primarily gas mixtures across the tops of the second baffles and into a second contact with each other.  Fourth baffles, disposed above the volume where the mixtures come into the second contact, cooperating with the housing, define a secondary precipi-tation zone and cause third retroversions of the mixtures towards and across the tops of the third baffles with the remaining contami-nants being centrifugally precipitated by the third retroversions into the secondary sedimentary precipitation zone for sedimentary precipitation on to the second baffles.  The sides of the housing cooperate with the fourth baffles to cause fourth retroversions of the gases towards and out of the outlet.

Abstract: Méthode et dispositif pour améliorer le fonctionnement d'un moteur à combustion interne, ayant une admission d'air, et équipé d'une turbine actionnée par les gaz d'échappement, cette turbine entraînant un compresseur d'air capable de délivrer par son orifice de sortie de l'air sous pression, lorsque son orifice d'admission communique avec l'atmosphère,  Pendant le fonctionnement du moteur, on repère les conditions opératoires du moteur, et en fonction de ces conditions opératoires, on impose au moteur un mode de fonctionnement choisi parmi un premier et un second modes de fonctionnement.  Le premier mode de fonctionnement est obtenu en alimentant le moteur en air sous une pression déterminée, exclusivement à partir d'une source statique, tandis que l'on maintient à une valeur faible le travail de compression produit par le compresseur.  Le second mode de fonctionnement du moteur correspond à l'alimentation du moteur en air délivré exclusivement par le compresseur, le passage de l'un à l'autre des modes de fonctionnement étant réalisé aussi rapidement que possible.  Pour ce faire, le dispositif comporte une source d'air sous une pression déterminée, un organe distributeur ayant une première position dans laquelle il met en communication ladite source et l'admission d'air du moteur et maintient à une faible valeur le travail de compression produit par le compresseur et une seconde position dans laquelle il met exclusivement en communication l'admission d'air du moteur et l'orifice de sortie du compresseur, et un élément de commande coopérant avec ledit organe distributeur pour obtenir rapidement son passage de l'une à l'autre de ses positions, pour des conditions prététerminées de fonctionnement du moteur.

Abstract: COORDINATE MEASURING MACHINE HAVING AUXILIARY AIR BEARING              ABSTRACT OF THE DISCLOSURE          An auxiliar air bearing system (50) for reducing friction in mechanical bearings (41, 42) to improve repeatability of measurements on a coordinate measuring machine (10).  The air bearing system (50) and mechanical bearings (41, 42, 43) support a moveable carriage (30) on a base (20).  The air bearing system (50) comprises an air pad assembly (70) mounted to the carriage (30), an air system (80) supplying air under pressure and a rail system (60) mounted to the base (20) with the air pad (70) including a compressed spring (76) captivated therein.  Air under pressure is directed between the air pad assembly (70) and the rail system (60), causing the air pad assembly (70) to lift from the rail system (60) and the base (20).  The air bearing system (50) and the spring (76) reduce the effect of any irregularities on the rail that would otherwise cause measurement errors.  The air bearing system (50) is preferably mounted obliquely to two of the mechanical bearings (41, 42) so that a single air bearing assembly reduces the friction in the mechanical bearings supporting the carriage in two directions.

Abstract: ABSTRACT OF THE DISCLOSURE          An article and its method of manufacture is disclosed wherein the  sheets of thermoplastic web material are bonded to form a laminated unit with an object captured therein.  Energy director element sets are disposed between adjacent sheets in an orientation such that when the layers are brought together with the object therebetween and a compressive force and high frequency vibratory energy are applied to the unit, the pressure and vibratory energy are concentrated at a first portion of the energy director elements so that the thermoplastic material in the region of the concentrated pressure softens.  A second portion of the energy director elements so aligned with, but spaced from the object to be captured between the sheets.  The spacing corresponds generally with the thickness of the energy director elements so that, as the first portion of the energy director elements melts during sonic bonding, the second portion of the elements approaches the abject.  As bonding is completed, the second portion of the energy director elements contacts the object to securely hold it between the bonded sheets.
