Abstract: 1523893 Centrifugal pumps NIKKISO CO Ltd 20 Aug 1975 [13 March 1975 (3)] 34529/75 Heading F1C In a pump comprising an impeller preceded by an axial-flow inducer coaxial with the impeller, axial counterflows in the fluid flowing from the pump inlet to the impeller are confined to the downstream side of the inlet so as to reduce noise caused by such counterflows. The first part 16a, Fig. 6, of the inducer is of smaller pitch than the second part 16b whereby fluid flowing back from the main impeller 14 is recirculated through the second part. An annular barrier 22 may be provided to cause fluid flowing back past the first inducer part 16a to be recirculated via the inducer. The axial distance between the inducer parts 16a, 16b, is equal to 0À85 to 0À95 times the inducer diameter. In the pump shown in Fig. 7, the inducer parts differ in diameter, the diameter of the part 16b being 0À9 to 0À97 times the diameter of the part 16a. As before fluid flowing back from the main impeller 14 is recirculated through the inducer part 16b. A sleeve 26 may be secured to the front end of the inducer part 16a, return flow originating in front of the inducer being deflected as shown by an annular flange 28. The part 16b of smaller diameter may be omitted, Figs. 1-3 (not shown).

Abstract: This invention relates to motor vehicles having passenger compartment heating devices. The temperature of the cooling water of an engine may be increased at idling speeds and low speed states by throttling the engine exhaust to increase fuel consumption. A throttle device is controlled in accordance with cooling water temperature and passenger compartment temperature, in response to activation by manual control. Manual control is overridden by an accelerator pedal actuated control when the load of the engine rises. Heat is extracted from the engine cooling water by means of a heat exchanger, through which air is driven into the passenger compartment. A brake is connected to an independently actuated device to throttle the exhaust to brake the engine. This arrangement is particularly suitable for use with diesel engines.

Abstract: A container for delivery and/or collection of a fluid, in particular a liquid. The container comprises an observation marking (9) which is adapted so as to show up in accordance with variations in the fluid level (10) in the container (1) for rapid indication of the quantity of fluid present at any given instant of observation. The observation marking (9) preferably comprises a first pattern (4) arranged on one side (3) of the container and a second pattern (6) arranged on the other side (7) of the container, the said first and second patterns being adapted so that by combined action with one another they give rise to a third clearly discernible pattern (9) in a direction of observation from the said other side (7) of the container on observation levels above the liquid level (10) in the container. The container (1) is manufactured appropriately from a flexible material, for example plastics, in the shape of a bag with at least one inlet (2) communicating with the interior of the bag. As a result of this the material properties of the bag can be utilized for a clearer showing up of the third pattern (9), since the two sides (6, 7) of the bag will be sucked towards each other owing to the vacuum which is produced in the empty space above the falling liquid level (10). A reading scale (14) adapted to the quantity of enclosed liquid may be arranged, for example, in association with the observation marking (9), so that the observation marking can be made use of also as a means for facilitating the accurate reading of this scale in that the observation marking clearly indicates the intersection between the liquid level (10) and the reading scale (14).
