Patent EP-0035838-A1 (EP)
Inventor: ADKINS RICHARD CYRIL
IPC: F04D27/02
Filed: 1981-02-23
Abstract: A diffuser has an upstream duct 11, a downstream duct 12, the adjacent ends 11A, 12A of the ducts defining a sudden enlargement of flow area. A fence 13 arranged downstream of the downstream end 11A of the upstream duct 11 defines the upstream end 12A of the downstream duct 12 and has a free edge 13A defining a flow area intermediate between that of defined by the adjacent ends 11 A, 12A of the two ducts 11,12. A chamber 14 at the outside of the upstream duct 11 has an opening 15 defined by the downstream end 11A of the upstream duct 11 and the free edge 13A of the fence. The ratio between the flow areas of the two ducts 11,12 at their adjacent ends lies between 1.4 and a minimum greater than 1. The above ratio provides high diffuser effectiveness with little or no bleed from the chamber 14. 
     Elements each comprising a diffuser as above may be arranged in flow-series to make possible a pressure rise greater than that given by a single element. A downstream one of the elements may have an area ratio greater than that of the preceding element(s) and its chamber 14 may be connected by a bleed line 18 to the upstream duct of one of the preceding elements, thereby to reduce the static pressure in the chamber and provide in respect of that downstream element, both a high area ratio and high effectiveness.

Abstract: Tobacco which has been increased in filling power by a conventional tobacco expansion process can be further increased in filling power by a post expansion heat treatment. The post expansion heat treatment comprises contacting the expanded tobacco produced by a conventional expansion process with a gaseous medium, such as air and/or steam, at a temperature of from about 93°C to about 232°C. The post expansion heat treatment is preferably conducted at a lower temperature than the temperature of the heating step of the expansion process, and thus can be more easily controlled, while providing an additional increase in filling power. The product of the post expansion heat treatment process of this invention has been found to be as acceptable in subjective smoking characteristics as the expanded tobacco which is treated by the process.

Abstract: Dans un moteur a combustion, le milieu de fonctionnement qui est de preference de l'air est induit et comprime avant l'alimentation en combustible et la combustion a lieu tout en effectuant un travail. En reponse a la charge du moteur, une grande partie reglable de la quantite maximum d'air admis a tout moment dans le moteur peut s'echapper sans etre comprimee. Seule la quantite d'air requise temporairement est comprimee et alimentee en combustible. De cette maniere, le volume de travail du moteur est regle en reponse a la charge reelle. Pour obtenir ce resultat, on incorpore dans le moteur pour chaque chambre de travail une soupape d'echappement qui est concue pour etre ouverte pendant une grande partie reglable de la phase initiale de compression du milieu de fonctionnement du moteur.

The circuit can be switched-over toastand-by state in which the energy supplied to the load is reduced to zero. A starting network (R16) is connected in such a way between the input voltage and the second switch that the current therein flows through the second switch during the period of time this switch conducts and does not flow to the control electrode of the first switch in the stand-by state.

Abstract: A method and apparatus for controlling acceleration and deceleration for accelerating and decelerating the frequency of a pulse train at the beginning and end of the pulse train. The method includes storing a frequency function (g(ti1256)) in a memory (101) in advance, which frequency function represents an acceleration characteristic or deceleration characteristic, reading the frequency function out of the memory (101) at a predetermined interval, computing a frequency at the present time, and generating pulses (Po), of a number corresponding to the product of the computed frequency and the predetermined time interval (At), during said predetermined time interval. Accordingly a movable element with little rigidity, such as a robot arm, can be started and stopped smoothly without vibration.
