Abstract: The digital-to-analog converter for converting a digital signal having a word length n into an analog signal comprises at least two switched capacitor integrators (1, 2) arranged in series and a control unit (18) for applying control signals to the integrators for performing an integration step in an integrator under the influence of a control signal applied to this integrator. Each integrator (1; 2) comprises a capacitor network (11; 12) comprising at least two capacitors (27.1, 27.2, ......; 28.1, 28.2, ....) coupled between the input (13; 4) of the integrator and the inverting input (-) of an amplifier stage (5; 6) associated with the integrator. A capacitor (9; 10) is coupled between the inverting input (-) and the output (7; 8) of this amplifier stage (5; 6). The control unit (18) is adapted to apply, in this order, a first control signal to the first integrator (1), a second control signal to the second integrator (2), a third control signal to the first integrator and a fourth control signal to the second integrator. The first integrator (1) couples a total capacitance of M1.Cref1 and M3.Cref1 during a given time interval to the inverting input of the amplifier stage (5) under the influence of the first and the third control signal, respectively. The second integrator (2) couples a total capacitance of M2.Cref2 and M4.Cref2 during a given time interval to the inverting input of the amplifier stage (6) under the influence of the second and the fourth control signal, respectively. For converting an arbitrary digital signal it holds that M2 + M4 is equal to a constant (k) which is preferably equal to 2 p  in which p≦n for converting a n-bit digital signal. Due to this measure an offset voltage which is independent of the value of the digital signal to be converted is produced at the output (8) of the converter.

Abstract: La présente invention se rapporte à un procédé servant à mesurer l'angle d'incidence d'un rayonnement et à un détecteur permettant de réaliser ledit procédé. Le contexte de la présente invention est constitué par certains rayonnements électromagnétiques, tels que le laser de longueurs d'ondes différentes allant de l'ultraviolet à l'infrarouge, dans lesquels apparaissent des irrigularités, des tavelures qui sont notamment causées par des turbulences dans l'atmosphère. Ce phénomène engendre des problèmes pendant l'enregistrement d'une courte impulsion de rayonnement unique ou d'un petit nombre de courtes impulsions de rayonnement. La probabilité de détection peut décroître considérablement en même temps qu'apparaissent des difficultés pour déterminer de façon fiable l'angle formé avec la source de rayonnement avec une haute résolution. La présente invention résout ce problème en plaçant au moins deux détecteurs (a, b, c, d) suffisamemt espacés entre eux pour leur permettre de recevoir un rayonnement qui ne présente essentiellement aucune corrélation dans le cas d'un rayonnement tavelé et en concevant les détecteurs sous la forme de deux éléments détecteurs (1, 2) montés suffisament proches l'un de l'autre pour leur permettre de recevoir essentiellement le même rayonnement dans une direction telle que les perpendiculaires de chaque élément détecteur respectif forment entre elles un angle connu (beta). On calcule ensuite l'angle d'incidence (alpha) au moyen des signaux (S1, S2) provenant des éléments détecteurs (1, 2), signaux qui dépendent de la forme des faisceaux de sensibilité, et on calcule cet angle (beta) formé entre les éléments détecteurs.

Abstract: The invention relates to a collecting and transport container, especially for waste products, having at least one filling and emptying opening, which can be closed by a lid, and having devices for setting down and lifting up during transportation. The object is to provide a container of this type, which, having an economic construction, ensures a high degree of safety during transportation on different means of transport, including a loading and unloading terminal, and can be emptied and cleaned satisfactorily. For this purpose, provision is made for the container (1) to have an approximately cylindrical central part (1a), having a cylinder axis which is approximately horizontal in the operating position, and at least one end wall (4) which is embossed on the outside. Mounted in the end wall (4) at the top is a large domed nozzle (6), the opening (8) of which encloses an angle of between 5 - 30 DEG  with the cylinder axis and the lowest point of the opening (8) lies above the highest filling level (A) in the operating position. The large domed nozzle forms a filling and emptying opening which, compared to a lid, forming the entire upper surface in known containers, offers the advantage of limited size and, for that reason, and due to its shape offers greater security in respect of sealing off and arresting.

Abstract: A weft threading system for threading a weft yarn prior to restart of weaving operation of a fluid jet loom. The weft threading system is comprised of a weft winding arm (10a) forming part of a weft storage unit (10), arranged to wind the weft yarn (W) on a drum under relative rotation between the weft winding arm and the drum. The weft winding arm is pipe-shaped so that air jet is passed therethrough and ejected from its tip end section. The tip end section of the weft winding arm is so bent that air jet ejected therefrom is directed to a weft guide (21) disposed separate from the weft storage unit and on the upstream side of a weft inserting or main nozzle (11). The weft guide is provided with a function to eject air jet in order to suck the weft yarn and project it therefrom, so that the weft yarn from the weft winding arm is automatically passed through the weft guide into the weft inserting nozzle.

Abstract: A process for the isomerization of C₄-C₆ paraffins with good stability and high conversion that uses a highly active catalyst to isomerize the feed (10) in the presence of very little hydrogen (14) which is selected so that the hydrogen to hydrocarbon mole ratio of the effluent (46) is 0.05:1 or less, and hydrogen is not recycled. Continued operation at low hydrogen concentrations in the reaction is made possible by the remarkably low coking tendency of the catalyst, especially during periods of temporary sulfur deactivation. The low hydrogen to hydrocarbon mole ratio feature simplifies the process and makes it cheaper to operate by eliminating facilities for the recovery and recycle of hydrogen. 
     The catalyst comprises alumina having 0.01 to 25 wt.% of platinum, and from 2 to 10 wt.% of a chloride component. The isomerization conditions in isomerization zone (16) include a temperature of 40 to 235 o C, a pressure of 7 to 70 barsg and a space velocity of 0.1 to 10 hr⁻¹. A chloride concentration of 30 to 300 ppm is maintained in the reaction zone (16).

Abstract: An electro-optic modulator device, such as a multi-gate light valve for an electro-­optic line printer, wherein the different elements are uniquely combined in a package utilizing VLSI principles. A specially designed integrated circuit package (140) is utilized to enable the bonding of one or two electro-optical devices (110, 112) as a single unit. As each electro-optical device has its chip pads at one end of the device, special modifications (175, 177) need to be made to join the pads to the external connectors. The electro-optical crystal, which may be mounted on a glass plate, is bonded to the integrated circuit chip. Sonic bonding or the two layer metal technique may be used for the crystal to chip bonding.
