A motor vehicle seat includes a longitudinal guide with a locking mechanism with a release device for locking and unlocking the locking mechanism in an engaged and in an unengaged position to allow movement of the seat. The backrest can be tipped forward and is connected to the locking mechanism. The locking mechanism unlocks when the backrest is tipped forward and for allowing manual movement of the motor vehicle seat in a longitudinal direction. A memory device serves to find the previously engaged position of the locking mechanism.

The present invention relates to a device for mounting a switch or the like on a mounting plate. The switch comprises a housing with a housing top side supported on the back side of the mounting plate, a fastening protrusion including fastening means, as well as a plurality of resilient tongues, each having a locking protrusion. The fastening protrusion and the resilient tongues are inserted for mounting purposes from behind into an opening of the mounting plate, with the locking protrusions locking in place with the front edge of the opening. Furthermore, the device comprises a fastening element that can be mounted from the front side of the mounting plate and cooperates with the fastening means of the fastening protrusion. According to the invention the resilient tongues extend from the housing top side substantially in vertical direction and are spaced apart from the fastening protrusion. Moreover, according to the invention the fastening element is formed by a sleeve that can be inserted from the front side of the mounting plate into the opening of the mounting plate.
摘要:
A process and device for separating oil and volatile organic components from pressurized gases of a compression system in which, before oxidation-catalytic separation, a physical separation is performed to protect the oxidation-catalytic separator against a large amount of oil being entrained in a surge in the pressurized gases. The resulting oil which has been separated in this physical oil separation is then fed back into the pressurized gas flow which is flowing to oxidation-catalytic separation in metered amounts. This results in the oil concentration in the pressurized gas entering the oxidation-catalytic separation means being maintained such that oxidation-catalytic separation can be carried out effectively and under optimum operating conditions without there being an adverse effect on operation by oil concentrations which are suddenly high for an instant.

An air pump assembly includes a pump module having an outer surface and a casing at least partially surrounding the pump module. The casing has an inner surface defining a cavity sized to snugly receive the pump module such that the outer surface of the pump module is in substantial engagement with the inner surface of the casing and is substantially prevented from moving with respect to the casing when the pump module is received within the cavity. At least one airflow passageway is defined between the inner surface of the casing and the outer surface of the pump module. The airflow passageway is configured so that air flowing through the passageway changes direction at least one time to reduce the transmission of noise from the air pump assembly.

The invention relates to a process for the recovery of low molecular weight C.sub.2+ hydrocarbons, in particular ethylene and ethane from a cracking gas, in particular from a fluid catalytic cracking waste gas. In accordance with the invention the light C.sub.2+ hydrocarbons are scrubbed out of the cracking gas by absorption, using an organic, preferably paraffinic, physically acting scrubbing agent, the scrubbing agent having a molecular weight of between 50 and 75 g/mol, preferably between 60 and 75 g/mol. Particularly suitable as scrubbing agents are pentane, isopentane or mixtures thereof. Prior to the generation of the loaded scrubbing agent, co-extracted methane is advantageously stripped off.

The invention is directed to a status-reporting device with a plurality of sensors which send output signals whose values depend on the status monitored by the sensors and with an evaluating device which is connected to the sensors and responds by sending an alarm signal when a preselected value of the output signals is reached. According to the invention, the evaluating device has an individual threshold switch (IC.sub.51) which generates the alarm signal and is connected with the output (3) of an interrogating device (IC.sub.3) which has a plurality of inputs (1, 2, 5, 12-15) connected to each sensor, respectively, and means (IC.sub.2) which connect the inputs (1, 2, 5, 12-15) with the output (3) periodically and one after the other. Also described is a temperature sensor which is particularly suitable for fire detection and fire extinguishing systems, as well as a process for the production thereof (FIG. 4).
摘要:
The aim is to separate, by cooling and partial condensation of C.sub.2+, C.sub.3+ or C.sub.4 hydrocarbons contained in a gas mixture comprising, in addition to these components, even lighter constituents. For this purpose, the gas mixture is at first cooled until condensation of a smaller part of the hydrocarbons to be separated, after which the mixture is fed into the lower region of a fractionating column. A gaseous fraction is removed from the upper region of said column and is then again cooled and partly condensed in a heat exchanger, after which this partly condensed fraction is conveyed to the top of the fractionating column in the form of a return flow. In the case of C.sub.4 separation, the C.sub.4 hydrocarbons must represent more than 50% of the hydrocarbons contained in the gas.
摘要:
An apparatus for determining the degree of water saturation of the hygroscopic desiccant of a disposable drying cartridge as a function of the variation in the dielectric constant of the hygroscopic material. The invention takes the form of a tubular capacitor disposed in the mass of hygroscopic desiccant material proximate the outlet of the drying cartridge, and of appropriate circuits for measuring the level of saturation of the desiccant material and for operating alarm and safety devices. A removable plug provides access to the cartridge mounted in a casing. The plug has a pair of electrical contacts acting to biasing position the cartridge in the casing and provide effective electrical contact with the capacitor.
摘要:
For the separation of C.sub.5+ hydrocarbons from a gaseous stream containing light hydrocarbons, C.sub.1 -C.sub.5, and, in some cases, lower boiling components, e.g., hydrogen, the gaseous feedstream, under pressure, is cooled, partially condensed, and separated into a liquid fraction and a gaseous fraction. The liquid fraction is separated by rectification under a lower pressure into a product stream consisting essentially of C.sub.5+ hydrocarbons and a residual gas stream predominating in components lower boiling than C.sub.5. The gaseous fraction separated after the partial condensation is introduced into a recontacting column wherein C.sub.5+ components still contained in the gas are scrubbed out. The scrubbing step is performed with a partial condensate of the overhead product of the rectification. The loaded scrubbing liquid is then introduced into the rectification as reflux.
