Title: Compresseur rotatif avec sensibilite reduite a la lubrification
Inventor: COOPER CLARK V
IPC: F04C18/356
Filed: 1996-10-09
Abstract: Dans les compresseurs de réfrigération, on peut atténuer l'insuffisance de lubrification liée à l'utilisation d'huiles de synthèse, telles que les huiles à base de polyesters, en recouvrant un élément sujet à l'usure par insuffisance d'huile avec un revêtement à base de carbone de type diamant. De manière spécifique, la pointe de la palette d'un compresseur rotatif est revêtue d'un revêtement à base de carbone de type diamant, constitué d'une alternance de couches de carbure de tungstène et d'un matériau lubrifiant, et ayant une épaisseur comprise entre 0,5 et 5,0 microns.

Abstract: Lame tranchante (30) permettant de découper des matériaux en feuille tels que film plastique ou feuille métallique. La lame tranchante (30) comporte une rangée de dents coupantes (50) formant saillie par rapport à une surface plate. La profondeur de coupe de la lame (30) est limitée par la hauteur de la saillie que la dent coupante (50) forme par rapport à la surface plate. De plus, l'espacement des dents coupantes (50) est suffisamment resserré pour que ces dents coupantes (50) forment une surface d'appui suffisante pour servir de support à la peau humaine. Ainsi, la lame (30) découpe le film plastique et la feuille métallique mais n'entame pas facilement la peau humaine.

Abstract: A method for characterizing the level of noise generated by a tire having a specific footprint configuration through analyzing the shape of the tires footprint and taking into account the tires aspect ratio. The method includes: a) measuring the noise level if the solution to the calculation is inside of a predetermined range; or b) reconfiguring the footprint if the solution to the calculation is outside of a predetermined range. The advantage of this method is that a tire designer can design a tire, taking into account noise level.

Abstract: The engine consists of a fixed part body (1) with an internal space
formed on the bottom by a cylindric hollow (2) disposed longitudinally
and axially containing the rotating cylindric body (3), supported
on crankshaft bearings (4), having a hollow system (5) on its outside
wall. Said cylindric hollow (2) communicates on its upper part
with cylindric hollows (6) set in parallel wherein the pistons
(7) slide. The outside hollows (5) are arranged on the piston persistence
bands (7) alternately at an angle to each other of 180°
so to reach in a sequence the position under the couples of pistons
(7), coming to their bottom dead center, thus achieving two rotations
of the said rotating cylinder body (3) for each working cycle of
the Otto-cycle. During the induction phase the mixture is introduced
into a cylindric hollow (6) through the valve (8) then closed by
piston (7) thereof, which goes down to compress the mixture itself
until reaching the bottom dead center at the same time in which
the relative outside hollow (5) thereof gets positioned so to form
a combustion chamber (9) with into a groove (10) a plug (11). The
activation in a sequence of plug (11) causes, as a consequence
of the explosion, the start of the clockwise rotating movement
of the rotating cylindric body (3). Then, the piston (7) rises,
exhaust gases are discharged through the valve (12), while the
sequential series of explosion phases which take place within the
combustion chambers determine the further movement of the rotating
cylindric body (3) which, through its protruding end part and a
reduction gear (13) with a camshaft (14) on main bearings (15),
activates the pistons (7) by means of connecting rods (16).

Abstract: A gasket of the invention is formed of a gasket member
extending substantially throughout an entire area to be sealed.
The gasket member includes a base metal plate (A10) and at least one
sealing member (A11) disposed on at least one of surfaces of the base
metal plate (A11). A sealing section (A11a) and a pressure affecting
portion (A11b) are formed in the sealing member (A11). The sealing
section (A11a) has a compressibility, while the pressure affecting
portion (A11b) has a height and compressibility less than those of the sealing
section (A11a). When the gasket is tightened, the sealing section (A11a) is
compressed to securely seal around a hole (H) to be sealed. The
pressure affecting portion (A11) having less compressibility is formed
near bolt holes (Hb), so that the gasket can be tightened easily
without gradually decreasing its tightening pressure.

Abstract: The device uses a power-supply circuit (121) to generate a potential (Vw)

potential (Vo) at an output to set the potential (Vw) at an N-well of a pMOS
pull-up transistor (Qu) equal to or higher than the potential at the source S and the
drain D of the pMOS transistor (Qu). The power-supply circuit (122) generates a
potential (Vs) approximately equal to VDD - Vth when Vo < VDD, and turns off
when Vo > VDD to prevent a current from flowing from the output OUT through
the pMOS transistor (Qu) to the power-supply potential VDD, where Vth is the
threshold voltage of the MOS transistors.

Abstract: The inventive method serves for producing open containers from a flat sheeting (4) consisting of a foam material or containing at least one layer of such a material, by drawing the sheeting with the help of a female (2) and a male tool (1) and by expanding the foam material with the help of a pressure reduction. The action sequence of one cycle of the inventive method is e.g. the following: positioning and clamping the sheeting (4) over the opening of the recess in the female tool (2); moving the male tool (1) into the recess and at the same time prestretching the sheeting with the help of a pressure difference between its two sides, such that the face of the male tool (1) gets in contact with the prestretched sheeting inside the recess; drawing the sheeting further by moving the male tool (1) to its end position in the recess of the female tool (2) and at the same time reducing the pressure on the female tool side or on both sides of the sheeting such that it reaches a value below ambient pressure which is sufficiently low for expanding the foam material and keeping the reduced pressure until the sheeting is cooled below plastication temperature; then equalizing the pressure and demolding and declamping the formed container and advancing the sheeting for a further method cycle.
