Title: Estimation du debit et compensation des oscillations de pression dues au debit dans le traitement par ventilation en pression positive continue et la respiration assistee
Inventor: FARRUGIA STEVEN PAUL
IPC: G01F15/02
Filed: 1996-09-13
Abstract: La présente invention concerne un procédé d'estimation du débit pendant le traitement par ventilation en pression positive continue. Ce procédé consiste à mesurer la vitesse de la turbine (32) au moyen des capteurs à effet Hall (80) du moteur. La pression équivalente, pest, qui serait développée par la turbine (32) pour cette vitesse mesurée si le débit était nul, est estimée grâce à une fonction mathématique déterminée. En même temps que l'on mesure la vitesse et que l'on estime la pression, la pression dans le tube d'arrivée, pact, est mesurée par le transducteur de pression (42) et, à partir de pact et de pest, on calcule la différence entre les deux pressions et elle représente une estimation du débit, fest. La valeur estimée du débit peut être rendue linéaire par le dispositif à racines carrées (86) puis filtrée par une combinaison de filtres passe-bas et passe-haut (90, 92) pour établir une valeur estimée filtrée du débit, de laquelle sont éliminées les composantes non respiratoires. L'invention concerne aussi un procédé de compensation de débit pour les oscillations de pression dues au débit.

Title: Railway braking systems
Inventor: POWELL PETER H
IPC: B61H13/02
Filed: 1989-11-03
Abstract: ABSTRACT            A railway braking system includes a hand-brake system and a service brake system, in which the hand-brake system is interlocked with the service brake system such that when the hand-brake system is applied the service brake system is rendered incapable of full brake release and is rendered incapable of being re-charged until the hand-brake system has been released. In a particular embodiment (Figure 1) the interlock is mechanically effected via valve-operating gear (13) of the hand-brake system acting on a fluid-control valve (12) of the service brake system.  First, second and third ports  (14,15,16)  of the valve  (12)  are respectively connected to an air reservoir (3), atmosphere and the remainder of the service brake system.   In the hand-brake system released condition the third port (16) is connected to the second port (15) open to atmosphere and the service brake system is unaffected by the hand-brake system.  Application of the hand-brake system connects the third port (16) to the first port (14) and hence to the air reservoir (3) to bring about and/or maintain brake application.

Abstract: A black/white liquid crystal display (10) contains a nematic liquid crystal having a twist of 270 DEG  between two cell plates. The product of the liquid crystal layer thickness and the anisotropy of the refractive index is approximately 0.38. A pretilt of approximately 15 DEG is present. The polarisation directions (P1, P2) are at an angle  beta  of 45 DEG  to the orientation directions (Mo, Mu). 
<??>Over a very large range of viewing angle, this display has a relatively low dependence on the contrast of the viewing angle, and there is practically no colour displacement at all that depends on the viewing angle. Because of the considerable improvements, when compared with all known cells, in the range of the viewing angle with respect to contrast and colour neutrality, the display is termed an "extended-viewing-angle" display (EVA display). It can be multiplexed to a very high degree.

Title: Intermittent steam injection
Inventor: ALAMEDDINE BASSEM R
IPC: E21B43/24
Filed: 1990-09-27
Abstract: A method for intermittent steam injection which comprises completing wells in more than one zone and selecting a number of wells as steam injectors.  As interwell communication (temperature breakthrough) develops, producers are shut-in to allow for the reservoir pressure to build up and heat to propagate from the channel of communication (e.g., fractures) to the reservoir matrix. The injection phase is followed by blowdown.  Thereafter, shut in producers and, in certain other cases, injectors are put on production.

Title: Wellbore heating process for initiation of below fracture pressure steam stimulation from a horizontal well located in an initially immobile tar sand
Inventor: SANCHEZ J MICHAEL
IPC: E21B43/24
Filed: 1990-09-28
Abstract: A steam stimulation process for removing viscous hydrocarbonaceous fluids from a reservoir penetrated by a horizontal wellbore. Steam is injected into the wellbore slightly above the reservoir pressure. Injection is continued so as to allow the steam to heat the reservoir by conductance. once thermal-stimulation is obtained to the extent desired, steam injection is stopped and hydrocarbonaceous fluids are produced to the surface. A void is created in the area adjacent the wellbore and hydrocarbonaceous fluids removed therefrom. Steam in an amount sufficient to fill the void is injected into the formation at pressures slightly above the reservoir pressure but below its fracture pressure. Afterwards, the steps are repeated.

Abstract: A  method  for  removing  unpleasant  organoleptic sensations  from  polydextrose-containing  confections  is disclosed.   Polydextrose solutions ranging from 50 to 70% are pH-adjusted from their typical pH of between 2.5 to 3.5 to levels of between about 4 to about 7,  preferably of between about 4.5 to 6.5, and most preferably from about 5 to  about  6.   The polydextrose  solutions  are  thereafter heated  to  form  confectionery  syrups  and  hard  candy  is thereafter made in the customary way.  Confections prepared in  accordance  with  this method  are  low  calorie  and of superior taste and mouth feel compared to non-pH-adjusted polydextrose  confections.    In  the  cases  where  it  is necessary to re-acidify hard candy syrups for particular confectionery formulas, it has been found that the choice of acidulants,  preferably  malic  and  adipic  acids,  provide superior confections.
