Abstract: An electrical extension particularly for use in a motor vehicle: a cylindrical cable storage container having two cables coiled therein. The cables are connected in series. The first cable is stored as a plurality of spiral turns arranged in a substantially flat disk in the bottom of the container. The second, less flexible cable is stored as a plurality of coils arranged one on top of the other against the interior wall of the container. The second cable is played out initially from the container for connection to an external power source. The first cable is connected to an electrical unit within the vehicle. The container may be stored behind the grille and under the hood of a vehicle. A operable cover sealed to and over the container may be pivoted to the hood.

Abstract: A sensor which is intended to detect the rotational position of a rotatable device, e.g. a shaft or a rotatable hatch, which is rotatable, preferably by a motor, incorporates a position detector and a potentiometer. To improve the potentiometer's accuracy within part of the relevant rotation range of the device, a cam mechanism is arranged between the potentiometer and the rotatable device.

Abstract: An extra U-shaped pressed plate profile (20) is arranged at the connection (13) between the A-pillar (3) and sill (5), inside a closed hollow beam running around the door aperture, which plate profile runs from the front lateral wall of the A-pillar obliquely rearwards to the lower lateral wall of the sill beam, thereby providing a double wall with spaced plates (26, 27). The double wall enables a local plastic deformation zone to be provided for impact of the wheel against the door aperture frame, and enables the wheel to be locked so that it does not migrate up the A-pillar, thereby providing controlled deformation and absorption of crash forces without the entire door aperture frame collapsing. The rear plate (27) forms a secondary closed hollow beam inside the door aperture frame which, during the deformation of the front plate (26), retains a closed stable door aperture frame with adjoining sections of the A-pillar (3) and sill (5).

Abstract: Arrangement for preventing rattling caused by a synchronizing ring [(36)] for an unengaged gear in a synchronized gearbox. When the gear is not engaged, its synchronizing ring is arranged for limited rotation relative to a hub arranged non-rotatably on a shaft [(6)] and relative to a synchronizing sleeve which is movable axially on that hub. Radially acting plate spring elements [(50)] are incorporated with prestress in the arcuate space [(45)] between an outer surface [(46)] of the synchronizing ring [(36)] and an inside surface [(48)] of the ridged rim [(34)] of the synchronizing hub. The plate spring elements [(50)] cooperate with the synchronizing ring [(36)] to hold the synchronizing ring in a position of suspension relative to the synchronizing hub [(10)] and thereby prevent it being rotated between its end positions and causing rattling.

In order to prevent misting of the inside of the windscreen after the vehicle has been parked with the engine shut off, the fan is deactivated and preferably also the fresh air intake is closed for a time period after switching on the air conditioning system.

Abstract: The invention relates to an engine with a constructional design and material composition for optimum thermal conductivity and vibration damping functions. The invention consists in the cylinder section (11) surrounding the combustion chamber being made of a light metal alloy and in the lower part of the cylinder section being connected to a crankcase section (13) with integral lateral walls (21,22) which enclose the cylinder section (11) with an air gap, and the crankcase section is made of a material with higher density than the cylinder section, preferably cast iron.

Abstract: A control module (1) for servo assisted window operation in motor vehicles comprises a number of individual controls (2a-2d) for the respective side windows and also other controls (3, 4, 5) for actuating the locking out of rear seat controls for rear side windows, the release of jamming protection and the roof hatch servo. The control module (1) is preferably intended for placing on a central console (16) between the vehicle's front seats for easy access by the driver. Each individual control (2a-2d) for the respective side windows not only has an asymmetry of shape pointing towards the respective window but is also designed with first and second operating surfaces (12 and 13 respectively) which made it possible to press the control downwards towards and lift it upwards away from a horizontal baseplate (6) of the control module (1) so as to permit logical actuation of the controls (2a-2d) with respect to the movement of the windows.

Abstract: The invention relates to a device and a method which can be applied primarily to computer controlled fuel systems for Otto engines, with sequential injection of fuel in each cylinder to the inlet valves. In order to utilize the capacity of the hot inlet valves for evaporating the fuel, in normal operating cases, the invention is characterized in that the start of injection is continuously adapted to the prevailing fuel demand and the injection time consequently required, so that the injection is substantially completed before the inlet valve towards which the injector is directed will begin to open.

Abstract: Control unit (1) for a cruise control system for a motor vehicle including at least one manually operated movable switch (4) for operating the cruise control system. The switch (4) has a neutral position (6) and can, when moved away from the neutral position (6) in a first direction, assume a first position (8) in which the switch (4) gives a control unit (21) a signal for temporarily switching off the system without cancellation of set speed. The switch (4) can also, when moved away from the neutral position (6) in the first direction, assume a second position (10) in which the switch (4) conveys signals to the control unit (21) in order to facilitate for the cruise control system to access, in some predetermined manner, a set speed stored in a memory unit situated in the control unit (21), where the second position (10) can only be reached by the switch (4) passing through the first position (8).

Abstract: Method and adjusting device for varying the compression of an internal combustion engine with a cylinder receiving section (2) which is pivotably mounted in the crankcase section (4) of the engine supporting the crankshaft, about a tilting shaft bearing (8) on one side of the engine, to effect a variation in the engine compression. A tilting mechanism (70) acting between the crankcase section and the cylinder receiving section is arranged on the side of the engine opposite the tilting shaft bearing (8), enabling the distance between the two engine parts to be varied. A hydraulic adjusting device (76, 78) is connected to the tilting mechanism (70) for adjusting the lateral tilting of the cylinder receiving section (2) relative to the crankcase section (4).

Abstract: An arrangement for the supply of fuel to internal combustion engines with different mixing ratios of methanol and petrol, and continuous transition during operation between different mixtures thereof which arrangement includes a main tank (2) and a slave tank (4), which slave tank must be isolated from the main tank so that its mixing ratio is not varied by filling, enabling the engine to be started on the same fuel as that on which it was stopped. The engine is supplied with fuel by a fuel pump (7) arranged in the slave tank (4), which fuel pump also drives an ejector (6) arranged in the main tank (2), so that fuel is entrained from the main tank (2) to the slave tank (4). Only one fuel pump (7) is therefore required.

Abstract: A process for indicating abnormal conditions in a motor vehicle by inducing misfires through the absence of fuel supply. The fuel supply is interrupted cylinder by cylinder in such a manner that the supply is interrupted during a proportion of the total number of injection cycles of the respective cylinders during a first fuel supply sequence, after which the next cylinder interrupts the fuel supply for a proportion of the total number of injection cycles of that cylinder during a subsequent fuel supply sequence. The interruptions of the fuel supply take place preferably as a predetermined number of injection cycles during a fuel supply sequence, and when each injection supply sequence is of equal length or includes a certain number of injection cycles. This can give rise to a distinct signal quality from the engine, in the form of irregular, uncomfortable engine running, while each individual cylinder is subjected to the least possible disturbance, apart from an ideal operating condition.

Abstract: A motor vehicle bumper for energy absorption. A support part of the bumper is supportable on the vehicle and is generally U-shaped with horizontally extending arms. A cover supported on the support includes respective wall sections that extend in from the top and bottom of the cover and cooperate with vertically outwardly extending flanges on the legs of the U. The wall sections of the cover are simply locked to the flanges of the support. A body of energy absorbing material is disposed in the cover and in the support and is pressed against the wall sections of the cover upon deformation of the cover by application of more than a predetermined force to press the energy absorbing material against the cover wall sections to prevent those wall sections from separating from the flanges of the legs of the U-shaped support in the event of collision or application of more than a predetermined force to the cover of the bumper.

Abstract: A device and method which can be applied primarily to computer controlled fuel systems for Otto engines, with sequential injection of fuel in each cylinder to the inlet valves. In order to obtain the fastest possible response with the smallest possible number of calculations of the fuel flow, the invention is characterized that it is the initiation of the opening or closing of the injection valve which immediately gives rise to a calculation of the instantaneous fuel demand. When the injector is activated for opening or closing, an interrupt is generated which, in the case of automatic opening, activates one complete calculation of the instantaneous fuel demand on the basis of the parameters which are detected at the time of opening or, at the time of closing, on the basis of a limited number of parameters which are indicative of the load enrichment requirement at the time of closing.

Abstract: A cast cylinder head of light metal incorporates a reinforcement made of a stronger material than the light metal. The reinforcement consists of a relatively narrow elongated steel plate (6) which stretches in a single piece along all the cylinders. The elongated steel plate (6) is provided with transverse arms (8) which stretch out approximately perpendicularly from the steel plate between the valve port apertures (3a, 4a, 5a, 6a) of each cylinder.

Abstract: Device for injecting air into an exhaust system fitted with catalytic cleaner for a supercharged Otto engine, in whose intake manifold is incorporated a motor driven air compressor operating with internal compression, giving rise to the supercharging. An air bleeding duct is arranged for adjustable air bleeding from the constriction zone of the air compressor to supply this air as additional air to the catalytic cleaner. This air bleeding duct extends from a point in the constriction zone to a point in the exhaust system upstream from the catalytic cleaner. In an inlet section of the intake manifold, located upstream from the compressor, is installed an electronically controlled device for engine idle control during bleeding of the air via the air bleeding duct.
