Abstract: A changeover device for an integrated turbo-ramjet engine has a nozzle ring (14) displaceable in the axial direction and an annular cone (11) which can be displaced counter to the nozzle ring. In turbo mode, the annular cone is situated in its forward position and the nozzle ring is situated in its rearward position, sealing off a ram- air inlet duct (16), and, in ramjet mode, the annular cone, in its rearward position, seals off the turbo inlet duct and the nozzle ring opens the ram-air inlet duct. It is thereby possible to perform low- loss introduction of the air flow into the turbo inlet duct (12) or the ram-air inlet duct (16) while, at the same time, no unfavourable enlargements in the diameter of the external housing of the engine are required.

Abstract: Absolute-measuring position transducer system for an in­dustrial robot which has one unit for each robot axis with a resolver (32) mechanically coupled to the axis movement. The unit has a revolution counter (405) which, on the basis of the resolver signals, continuously indicates within which revolution the resolver is, and an R/D converter (406) for accurate determination of the resolver position within each revolution. During normal operation the resolver is supplied from an oscillator (403). In case of drop out of the supply voltage to the axis unit, the resolver is switched for pulse mode operation via a second oscillator (404) and the R/D converter is disconnected. The second oscillator (404) and the revolution counter (405) are then supplied from an accu­mulator battery (402).

Abstract: In ultrasound proximity switches with a separate electronic evaluation system and different sensor designs, the evaluation parameters normally need to be adapted to the respective sensor type. In order to avoid errors in this respect, it is advantageous if the switchover on connection of a new sensor takes place automatically. Sensor recognition has hitherto been implemented, for example, through manual coding or different voltage levels, which are connected to a sensor output signal. The proneness to interference and the cost of this method when a plurality of sensors are used are to be reduced. To achieve this, the oscillator frequency (2) associated with the sensor type is indicated with the aid of a counter (3) by a pulse-width modulated signal which corresponds to the pulses of the oscillator frequency counted according to the counter reading. This counter (3) is advantageously accommodated on an integrated circuit, with which a pulse-width modulated signal is already generated as temperature information.

Abstract: In a pipe lead-through for a wall, having a terminating edge (32), especially for a cab rear wall (30) of a vehicle (10) having an opening which can be closed by means of a rear flap (24), the wall (30) has a preferably U-shaped recess (34) which is open to the terminating edge (32). The recess (34) can be closed in a sealing manner by means of an insertable insert (36), which contains at least one through-opening (38) in its central region for at least one pipe (40). The surfaces of the insert (36) are shaped such that, in the inserted state, they do not project beyond the outer contour of the wall (30). For insertion of the insert (36) into the recess (34), the insert (36) and recess (34) have means of guidance, for example in the form of a guide web (48) and groove (44). The through-opening (38) for the pipe (40) has a skin (50) extending over it, which can be cut off to correspond to the pipe cross-section. <IMAGE>

Abstract: An apparatus for regulating the inflow of fuel into the intake duct of an internal combustion engine comprises an electrovalve installed in a fuel inflow duct leading to the intake duct downstream the speed governor organ; the times of excitation of said electrovalve are a function of some operating parameters typical for the engine, and the fuel inflowing into it comes from a fuel container cup equipped with level control means. The electrovalve is substantially positioned at the same level as of the cup. 
     The proposed arrangement makes it possible the amount of fuel mixed with air to be automatically corrected, in order to compensate for the changes in mixture composition due to the changes ocurring in some non controllable engine operating parameters.

Abstract: A method is provided for removing mercury from hydrocarbon fluids by high temperature reactive adsorption. A hydrocarbon feed passed through an adsorbent mass including a reactive adsorbent such as silver or copper sulfide on an alumina support. The optimum temperature of the feed to be treated depends upon the 90% boiling points corresponding to heavier feeds. A hydrocarbon condensate feed may be drawn from a stabilizer column in a natural gas processing plant at a temperature in excess of 204°C (400° F). If a metallic silver/alumina adsorbent is employed, the adsorbent may be regenerated through high temperature oxidation. Once oxidation is complete, the temperature is lowered in a reducing or inert atmosphere.

Abstract: A drill bit has an extendable and retractable undercut portion for the drilling of undercut holes, for example to accommodate anchor bolts in concrete. 
     The device includes a drill bit (18) for drilling an initial hold (B) to a predetermined depth at which stage a flange (12) on a guide sleeve (10) contacts the surface (A) of the workpiece. Further downward movement of the drill bit which is securely attached to a lower shank (4) of a body (1), causes relative upward movement of the guide sleeve (10) around the body (1). This in turn causes drive balls (17) accommodated within the flared upper end (11) of sleeve (10) to move inwardly and force apart tapered surfaces (3) and (6) on the body (1) and a slide sleeve (5) disposed between the shank (4) and sleeve (10). The slide sleeve (5) which carries dependent fingers (22) within flutes (20) along the length of the bit (18), thus moves down relative to the bit, forcing the lower ends of the fingers (22) over tapered lower ends (21) of the flutes, exposing cutting edges (24) on the ends of the fingers to grind an annular undercut groove (C) in the hole (B).

Abstract: An actuator is driven in a first direction by equal working fluid pressures acting on different piston areas acting in opposite directions, and is driven in a second direction by applying equal pressures on both sides of one of the piston areas. Working fluid from an inlet port (71), acting in a working fluid chamber (27), on one side of the piston moves a valve plate (36), closing vent ports (33) and opening working fluid discharge ports (32), thereby permitting the working fluid to push the piston (21) in a first direction. Working fluid contained in the working fluid chamber (21) is exhausted from working fluid discharge ports (32) to the outside of the system through a working fluid discharge tube (52). When the movement of piston (21) reaches its limit, a valve plate (36) is engaged by a spring (41), thereby causing simultaneous closing of the working fluid discharge ports (32) and the opening of the vent ports (33). As a result of the opening of the vent ports (33), working fluid pressures in the working fluid chamber (27) and a second working fluid chamber (26) are equalised. The effective piston area facing the second chamber is greater than the effective area facing the first chamber so the direction of piston movement is reversed. The working fluid discharge pipe (52) is fluid-tightly fitted through the piston (21) so as to provide a discharge path of working fluid from the system.

A cover or screws are not required for mounting the shield plate (4) in a simple structure. Moreover, if the whole shield plate (4) is of translucent, an engaging state, etc. can be visually observed, and the mounting of the shield plate becomes easier.

Abstract: Method and device for automatically adjusting the play of the rockers for an internal-combustion engine. By means of a preferably stepping motor (19), the adjusting screw (23), the lock nut of which has been slackened, is rotated in such a way as to lift the valve from its seat. When a sensor detects the stopping of the valve, corresponding to its return to the closing position, the adjusting screw is rotated through an additional angle predetermined and corresponding to the play to be obtained, and the lock nut (30) is then tightened again. Advantageously, a shim having parallel faces is inserted beforehand between the adjusting screw and the valve, and towards the end of the operation this shim is removed, and the additional angle just mentioned allows for the thickness of the shim. <IMAGE>
