The present disclosure provides a control strategy for balancing injector-to-injector fueling variations for a combustion engine having multiple combustion chambers (and cylinders), with multiple individually actuated injectors for injecting fuel into the combustion chambers, wherein at least one injector is assigned to each combustion chamber and a common rail supplies fuel to the multiple injectors. The method includes changing the actuation waveform of an injector assigned to a combustion chamber having an exhaust gas temperature deviating by more than the predetermined value from the average exhaust gas temperature, in order to change the amount of fuel injected.

A recording apparatus includes a housing that has a top wall section on which a top opening is provided, a top opening / closing body that is capable of being disposed at a closing position at which the top opening / closing body covers the top opening, and a recording unit that performs recording on a medium inside the housing. The top opening / closing body disposed at the closing position makes a sliding movement from the closing position, thereby causing the top opening to be exposed.

Method for maintenance of high-voltage switchgear / fuses in an installation, which method is performed while the switchgear / installation is under operation / voltage. It is further provided a device for carrying out the method, which device includes screening plates 20A-C, which screening plates are provided with maneuvring means 22 and 25, fastening means 23 and 24 for fastening of the screening plates to the switchgear cell / installation and means for disconnecting the switch 27, 28A-B.

In a plasma processing apparatus, a check valve is installed close to a refrigerant inlet of a compressor. When performing maintenance of a sample stage, refrigerant collected from a refrigerant flow path is temporarily stored in a flow path section extending from an expansion valve to the check valve, making it possible to perform the maintenance without changing the amount of refrigerant in the refrigerating cycle. With a refrigerant storage tank, a refrigerant supply valve, and a refrigerant discharge valve included in the refrigerating cycle, when maintenance of the compressor, a condenser, or the expansion valve is performed, the refrigerant collected from the refrigerating cycle can be put in use again.

An aircraft propulsion assembly comprising at least a main turbine mounted along a longitudinal axis, at least one main fan arranged upstream of the main turbine along the longitudinal axis and driven in rotation by the said main turbine, the said main fan being ducted by a main fan casing, an auxiliary turbine mounted along the longitudinal axis, the auxiliary turbine being independent of the main turbine, an auxiliary fan of axis offset with respect to the longitudinal axis and driven by the auxiliary turbine, the auxiliary fan being ducted by an auxiliary fan casing, the main casing being separate and distinct from the auxiliary casing so as respectively to generate a main secondary flow and an auxiliary secondary flow which remain independent of one another until they are discharged into the atmosphere.

An alternator for a vehicle has a housing that is formed with attachment holes in external portions of the housing, through which a carrier jig is passed, to support the alternator when it is being mounted in the vehicle. By forming a plurality of attachment holes oriented along a common axis, at respectively different positions on the exterior of the alternator housing, it can be ensured that the carrier jig reliably holds the alternator in a required attitude as it is moved into position for mounting, e.g., to be attached to a sloping side of the engine of the vehicle.

A two way gate valve includes a valve chamber having a first entrance coupled with a first chamber, a second entrance coupled with a second chamber, and an openable and closable chamber cover; a moving module having a first sealing plate for sealing the first entrance, a second sealing plate for sealing the second entrance, and a moving module body to which the first and the second sealing plates are mounted; a push-pull module having a push-pull module body coupled with the moving module body such that the moving module body can linearly move, a first operating body for moving the moving module in a first entrance direction such that the first sealing plate seals the first entrance, and a second operating body for moving the moving module in a second entrance direction such that the second sealing plate seals the second entrance.

The RO installation for producing ultrapure water, preferably for medicinal flushing solutions, with a raw water supply conduit, which leads to a feed tank, from which a conduit with a pump leads to the primary side of an RO membrane, from where a concentrate circulation conduit leads back to the feed tank, and with a permeate feed conduit and a first permeate circulation conduit, which either extends to a permeate return conduit, which leads to the feed tank, or communicates via a further permeate circulation conduit with the secondary side of the RO membrane, and with a filtrate outlet conduit is characterized in that the primary circuit including the feed tank, the conduit, the primary side of the RO membrane and the concentrate circulation conduit and the secondary circuit including the secondary side of the RO membrane, the first permeate circulation conduit and the further permeate circulation conduit may be flowed through by a disinfecting and cleaning agent independently of one another, wherein a disinfecting agent conduit connected to a disinfecting agent container communicates with the first permeate circulation conduit and the disinfecting agent conduit is provided with a disinfecting agent pump and that the permeate return conduit includes a pressure holding valve with a bypass valve.

A case for powdered cosmetic product includes at least one cover and one base which are movably mounted against one another between at least one closed position and one open position of the case, wherein the base includes a cavity intended to receive the powdered cosmetic product, which is closed by an opening / closing device configured to selectively deliver the powdered cosmetic product, the opening / closing device including at least first opening / closing means which, including first orifices (in communication with the cavity, are secured to the base, and second opening / closing means which, including second orifices, are rotatably mounted with respect to the first means between at least one blocking position and one usage position, wherein the first means include at least one first flexible membrane and the second means include at least one second flexible membrane.

A cooling device is disclosed. The cooling device includes a cooling section which is moveably provided with respect to an image forming device body between a first location and a second location, the second location being different from the first location, and which cools surroundings with a cooling medium to be supplied; a cooling medium supply section which is provided at the image forming device body and which cools the cooling medium to supply the cooled cooling medium to the cooling section; and a connecting member which connects the cooling section and the cooling medium supply section to circulate the cooling medium between the cooling section and the cooling medium supply section, wherein the connecting member includes a flexible member and is supported by a guiding member which guides an operation of tracking the connecting member in conjunction with movement of the cooling section.
