Title: Systeme de regulation de pression destine a une pile electrolytique a eau
Inventor: FAIRLIE MATTHEW J
IPC: C25B15/02
Filed: 2000-04-28
Abstract: L'invention concerne un appareil et un procédé pour fournir de l'oxygène et de l'hydrogène à une pression minimale désirée depuis un électrolyseur qui contient: une solution d'anolyte ayant un certain niveau de liquide d'anolyte; une solution de catolyte ayant un certain niveau de liquide catolyte; de l'oxygène généré à une pression d'oxygène au-dessus dudit anolyte; et de l'hydrogène généré à une pression d'hydrogène au-dessus dudit catholyte et destiné à passer à travers un système de sortie pour hydrogène. Le procédé consiste à élever la pression de l'oxygène au-dessus de celle de l'anolyte pour obtenir un différentiel de pression positif entre le niveau de catholyte et le niveau d'anolythe, égal à une valeur présélectionnée afin d'obturer la sortie d'hydrogène et d'obtenir une augmentation de pression de l'hydrogène afin qu'elle soit égale à une valeur à laquelle s'effectue l'ouverture du système de sortie d'hydrogène permettant de fournir de l'hydrogène à la pression désirée. L'hydrogène est fourni sur demande, à une pression qui permet son utilisation immédiate, par exemple, pour la production d'un hydrure de métal ou aux fins de son acheminent vers un compresseur puis vers une installation fonctionnant à une pression plus élevée; l'oxygène est fourni à des fins de respiration ou de nettoyage antiseptique. Le différentiel de pression à travers la membrane cellulaire est faible ou négligeable, et ce indépendamment de la pression des produits hydrogène et oxygène.

Filed: 1989-10-17
Abstract: In a method of setting the mean value of the supply temperature (T V) of  a  heating  medium  which  is  intermittently  heated  by  a  heating apparatus (5) in a heating system comprising at least one adjustable throttling point (16, 17, 18) for the heating medium, a desired supply temperature value (T S) is determined on the basis of external influencing factors (H,  T external)  and the heating medium is heated  to  the desired supply temperature value (T S) with the throttling points (16, 17, 18) fully open.  The mean value of the supply temperature is to be controlled to such a value that an optimum total throughflow rate of the heating medium is achieved, i.e.  the throttling points formed by thermostatic.  radiator  valves are  to be  partially open.   For  this purpose,  a starting function is determined with which the  temporary temperature (T V) changes during heating,  at least one parameter (C m) of this starting function is changed to fix a desired function, and the desired supply temperature value T F is changed until the course of heating has matched the desired function in each heating-up phase.

IPC: H02M7/527
Filed: 1989-11-22
Abstract: Inverters (5.1, 5.2) for feeding a three-phase load such as, for example, an asynchronous machine (6), are controlled by pulse width modulation,  in such a manner that they supply output voltages (U5.1R, U5.2R) which are  as  closely  sinusoidal  as  possible,  having  few harmonics per alternating-current phase (R, S, T). To achieve the pulse width modulation, a first auxiliary alternating voltage (U~1) of a sawtooth generator (1.1), on the one hand,  and a second auxiliary alternating voltage (U~2) of a sawtooth generator (1.2), which is phase-shifted by 180° with respect to the first one, on the other hand,  is superimposed by a control signal transmitter (2) on a sinusoidal first superimposition alternating voltage (UStR, UStS, UStT) with the required frequency and phase angle in logic circuits (3.1, 3.2). Separate inverter groups (5.1, 5.2), the outputs of which are connected via a reactor coil (7), the center tab of which is connected to a stator winding (WR) of the asynchronous  machine (6), are controlled in dependence on intersections of the two superimposition voltages in each case.  To reduce the turn-on and turn-off losses, the thyristors (T1, T1'; T2, T2 ' ) of the inverter are only switched over at intersections of the rising portion of the auxiliary alternating voltage (U~1, U~2). During this process, the inverter sections of the two phases (R, S, T),  the first superimposition alternating voltage of which has been intersected are in each case switched at two successive intersections whilst the inverter sections of the adjacent phases are switched over at the subsequent third  intersection.  This  allows  the switching actions to be reduced by 1/3.

Patent CA-2011489-A1 (CA)
IPC: B26D1/62
Filed: 1990-03-05
Abstract: An improvement in web-converting rewinders of the type which includes a perforator cylinder, and a bedroll/chop-off roll combination (21, 23) comprising a set of chop-off blades (31, 32), some of which chop-off blades (31) are disposed on the bed roll (21), and some of which (32) are disposed on the chop-off roll (23); and in which a running web is forwarded from an unwinding parent roll, and is converted into consumer product rolls such as, for example, tear-separable multi-sheet rolls of toilet tissue or paper towels. The improvement comprises parallel-motion chop-off blades (31, 32) which can be more closely spaced than in prior art chop-off blades, and thus induce greater stretching and more positive breaking of the web; and, preferably, the chop-off blades (31, 32) are disposed to act on a longer machine-direction-length of the running web than contemporary rewinders to enable more positively inducing roll endings by breaking along transverse lines of weakening rather than by inducing ragged transverse tears of web. Such a disposition of the chop-off blades (31, 32) is said to provide a wider window in which the lines of weakening in the running web may be indexed during each roll-ending chop-off event. Such an indexed relationship between the chop-off mechanism (20) and the running web is easier to continuously maintain with such a wider window, all other factors being constant. This invention is particularly useful for webs such as creped paper which must be stretched substantially in the machine direction before they will break along transverse lines of weakening such as lines of spaced cuts or lines of perforations.

IPC: G02B5/32
Filed: 1990-07-26
Abstract: A recording medium has a first fringe pattern which is described by a first spectral bandwidth and a first image blur factor.  The recording medium also has a second fringe pattern which is described by a second spectral bandwidth and a second image blur factor, the first spectral bandwidth being different from the second spectral bandwidth, and the first image blur factor being substantially equal to the second image blur factor.  By providing multiple holograms in the single recording medium, the spectral bandwidths of each hologram are combined to provide an overall spectral bandwidth.  Since the image blur factors of each hologram are substantially the same, i.e., overlap, when the two holograms are combined, the overall image blur factor is not increased. Indeed, it decreases at the same time the thickness of the recording medium is increased by a factor which is equivalent to the number of exposures in the single recording medium.  The result is increased bandwidth without a concomitant increase in image blur.
