Title: Internal combustion engine intake valve
IPC: F01L3/20
Filed: 1988-02-23
Granted: 1992-04-29
Abstract: An improved intake valve (50) for an internal combustion engine has a ridge (62) extending from the downstream side of the periphery (64) of the valve head (56) to aid in the improved aerodynamic flow of the fuel/air mixture gas through a valve opening. The ridge (62) acts as the middle portion of an ideal aerofoil and thus reduces the back pressure, and hence the drag, presented by the valve (50) to the flowing gaseous fuel/air mixture. The extent of the ridge (62) is selected to be between five and twenty five percent of the diameter of the valve head (56) and the thickness of the ridge wall is selected to be as narrow as possible consistent with long term performance. The ridge on the bottom of the valve head also flows less efficiently in the reverse direction, thereby allowing more desirable valve timing and cycle overlaps.

IPC: G03G15/00
Filed: 1988-01-15
Granted: 1991-11-27
Abstract: Disposable cartridges for smaller photocopiers and laser printers often have, in addition to a new-toner container and a residual-toner container, further functionally important parts, such as photoconductor drums and loading and developer stations, the additional parts being of considerable importance for the price of the cartridge. The invention is based on the idea of making such disposable cartridges reusable. This is achieved by means of a method, according to which the toner containers of the disposable cartridges are subsequently provided with refilling and emptying orifices which can be closed by means of lids, adhesive strips or plugs. <IMAGE>

Abstract: Le procédé décrit sert à mélanger des liquides les uns avec les autres ou différentes phases avec un liquide, en utilisant une double boucle de circulation créée sous la zone de surface d'un réacteur, de façon à assurer un mélange intensif. Le principe de roulis de fond toroïdal, selon lequel fonctionne le mélangeur utilisé dans la présente invention, se caractérise par le fait que le mélangeur présente une forte aspiration de fond et subit une pression dirigée obliquement vers le bas et par le fait que le mélangeur est installé pour permettre la réalisation du procédé de mélange de la présente invention et que sa configuration d'écoulement est régulée d'une façon déterminée avec précision. Dans ledit procédé, le jet du mélangeur heurte la surface de cylindre du réacteur, de façon à se diviser en deux parties approximativement égales par réglage de cette répartition au moyen d'un élément de guidage de contre-courant, lequel est placé au-dessus du mélangeur. Le mouvement de roulis qui se produit dans le réacteur est régulé au moyen de chicanes spécifiques.

Title: Resolution process for racemic spiro-hydantoins
IPC: C07B57/00
Filed: 1989-07-19
Granted: 1993-09-01
Abstract: A novel three-step process for resolving a racemic spiro-hydantoin compound into its optical antipodes is disclosed, which involves (1) reacting said racemic compound with an optically-active asymmetric isocyanate of the formula RNCO, wherein R is (S)- or (R)-1-phenylethyl or (S)- or (R)-1-(1-naphthyl)ethyl, to form the corresponding diastereomeric ureido compound; (2) separating the resulting diastereomeric mixture into its component parts, and (3) thereafter converting the separated ureido diastereomers obtained in step (b) to the corresponding asymmetric hydantoin compounds by treatment with an alkali metal lower alkoxide (C1-C4), followed by acidification, whereupon the desired optical isomer is obtained. The final products so obtained, such as (4S)-(+)-6-fluoro-2,3-dihydro-spiro[4H-1-benzopyran-4,4 min -imidazoli dine]-2 min ,5 min -dione (sorbinil) and (5 min S)-3 min -chloro-5 min ,6 min ,7 min ,8 min -tetrahydro-spiro[i midazolidine-4,5 min -quinoline]-2,5-dione, are known to be useful in preventing or alleviating certain chronic diabetic complications. The aforementioned diastereomeric ureido intermediates are novel compounds.

Granted: 1994-04-27
Abstract: To measure certain parameters of a gaseous, liquid or solid medium (2), two transmission paths (8, 9) for transmitting ultrasonic signals (51, 52) are formed, at least one of which is located in the medium (2) to be measured. Using at least one (51) of the mutually associated ultrasonic signals, a reference time (Tr) is transmitted. At the receiving end of the measuring arrangement, the receiving times of the mutually associated ultrasonic signals and a first electrical measurement signal (36) corresponding to the reference time and a second electrical measurement signal (37) corresponding to the time interval between the two receiving times are formed. The quotient of the first and the second electrical measurement signal is multiplied by the actual reference time (Tr) and thus provides the actual time displacement (dT2) between the two mutually associated ultrasonic signals, which is processed further for determining the value of the parameter to be measured. <IMAGE>
