Abstract: 1492090 Filtration; ultrafiltration ALFALAVAL AB 8 Dec 1975 [23 Dec 1974] 50248/75 Headings B1D and B1X In filtration or 'ultrafiltration' using a filter or in cleaning the filter fluid flows along the upstream side of a filter 3 and creats a pressure gradient along the upstream chamber 1, and a corresponding pressure gradient is maintained along the filtrate chamber 2 so that the pressure drop across the filter 3 is uniform over its whole area. In Fig. 1 pumps 5, 11 recirculate unfiltered fluid and filtrate, and a net flow of filtrate is discharged by valve 9. In Fig. 2 (not shown) filtrate chamber 2 is divided into sections, each connected to one branch of a manifold (17) along which a pressure gradient is maintained. Fig. 3 (not shown) illustrates three filter units as in Fig. 1 operating in parallel. In Fig. 4 (not shown) there is no recirculation of filtrate, but filtrate chamber 2 is of tapering section to produce a pressure gradient. In Fig. 5 (not shown) filtrate chamber 2 is defined between filter 3 and a rubber membrane (20), and some unfiltered fluid flows through a throttle (24) and along the other side of the membrane, which transmits its pressure to the filtrate chamber. In Fig. 6 (not shown) a uniform pressure drop is maintained by directing cleaning fluid, which may be a solvent, through the chambers on both sides of a filter, avoiding the creation of reverse pressure gradients. 'Ultrafiltration' means filtering particles below 0.5 micron dia. but above molecular weight of 500.

Abstract: The invention relates to multi-spot-welding machines for the production of lattice gratings suitable for use for example as walk ways, and which consist of upright flat bars parallel to one another and cross-bars welded transversely into these and again parallel to one another. The flat bars are usually fed intermittently to welding electrodes. The machine of the invention has at least one pair of cooperating electrodes which are aligned in the feed direction of the flat bars and spaced apart a distance substantially equal to the desired spacing of the cross-bars. The or each pair of electrodes is pressed in turn against each pair or cross-bars to be welded and the upright flat bars themselves act as current bridges between the electrodes of the or each pair. An abutment supports the flat bars against the force of the welding electrodes and this abutment has considerably greater hardness and wear resistance than the flat bar material. The abutment is of suitable design and is suitably positioned to correct the deformation of the longitudinal bars which occurs when the transverse members are welded thereon.

Abstract: In a combustion device, a swirl nozzle and a metering pump are connected to one another in such a way that as little dead space as possible exists between the delivery space of the metering pump and the swirl chamber of the nozzle. This makes it possible to atomise fuel through a swirl nozzle using a metering pump. Because it is possible for the metering pump to deliver for a period of just 2 ms for each pulse, at a frequency of 3 Hz, the delivery rate from the swirl nozzle can be reduced from the nominal value of 3 l/h to about 0.25 l/h. The atomised quantity of fuel is ignited by an ignition spark in a manner similar to that in a high-pressure atomiser system. Hence combustion is a combination of pressure atomisation and wall evaporation but is initiated by high-voltage sparks.

Abstract: An electric filter has a chamber or case (1), through which the air or other gas to be cleaned is directed by means of a fan (4). An ionisation device has been arranged for the gas to be cleaned, the device consisting of one or several ionisation electrodes (9) and counter electrodes (10). An electrostatic field is formed by positive and negative electrodes (13, 14), of which the plate-like collector electrodes (14) are at least partly of glass or corresponding material and on which there tend to accumulate from the air or other gas to be cleaned the impurity particles which have received a charge from the ionisation device. There acts as the collection electrodes (14) a water film continuously flowing over a plate made of glass or material reacting to water in the same fashion as glass. Thus the dry and solid particles such as quartz or carbon dust contained in the gas to be cleaned are carried along with the water film without rebounding from the electrodes in exchanging their original charge for a charge with the same sign as that of the collection electrodes. In the direction of the upper edge of the solid plates of the collection electrodes (14) there are arranged for directing a water current to the plate water leading parts, for example pipes (15) having small holes or longitudinal apertures for a water current.

Abstract: A pressure-reduction device forms part of a quick coupling in the first and/or second part of said coupling. The part of the coupling concerned thus comprises a first valve member (4 or 5) equipped with a valve body being either fixed or capable of linear displacement by means of which a first passageway for the fluid is able to be opened and closed. The device includes a second valve member arranged in said valve body comprising a ball (17, 30) capable of being caused to bear against a seat (18) by means of a spring member arranged in a recess in the valve body. Said ball is raised against the effect of said spring member when the first and second parts of the coupling are connected together. In so doing the ball opens a second passageway for said fluid before actuation of the first passageway takes place, thereby creating a pressure-reduction effect in the part of the coupling concerned thanks to a small quantity of the fluid being diverted from the inside of the part of the coupling via the second passageway. The spring member (14, 33) acts upon the spherical member (17, 30) via a power transmission member (19, 20). The latter is guided by the wall (21a) of the recess and/or by the inside and/or outside (14a/14'') of the spring member. The power transmission member is so arranged as to permit the flow of fluid to pass into the recess during the aforementioned process of being diverted.
