Sensor for an air-conditioning system in a vehicle

Abstract: In a sensor (3) for an air-conditioning system in a vehicle, the measuring head (15) of the sensor is provided with a number of solar cells arranged in a defined pattern for determining the intensity of the solar radiation and the position of the sun relative to the sensor. Attachment elements (6, 7) on the sensor permit assembly of the sensor only in one way in the vehicle.

Communications unit for fitting in vehicles.

Abstract: A communications unit with a telephone receiver (1) is intended for fitting in a standardized recess (3) for radio equipment in vehicles. The communications unit permits a fitting in which the telephone receiver (1) in a first user position lies sunk and protected in the recess (3). By means of an automatic or manually initiated ejection, the telephone receiver (1) is caused to take up a second user position in which the receiver (1) is given another orientation and a more advanced position relative to the recess (3). In this second position the telephone receiver (1) can be picked up from a telephone receiver holder (20) for manual handling. The invention permits a safer handling of the telephone while driving, and without obstructing the accessibility to other vehicle controls in the vicinity of the recess (3) when the telephone receiver (1) is in its first user position.

Arrangement for a transparent covering element with an electro-chromatic layer

Abstract: A covering element (1) consisting of transparent material is designed with an electro-chromatic layer (3-7) for control of the transmission of light through the covering element (1). The electrical power which is required for control of the electro-chromatic layer (3-7) is obtained from a photo-electric layer (9-11) integrated in the covering element (1). The photo-electric layer (9-11) is arranged outside the electro-chromatic layer (3-7). By means of the arrangement, when the light is at its most intensive, a high voltage is obtained from the photo-electric layer (9-11) and can be transferred to the electro-chromatic layer (3-7) so as to in this connection reduce, at least to a considerable extent, the transmission through the covering element (1). The arrangement can, within vehicle technology for example, be used in a sun-roof in order prevent heating up of an interior space in sunny weather. By means of the arrangement, the transmission is automatically adapted according to the light. The arrangement also leads to the complete elimination of the risk that the vehicle battery will be discharged, since all the energy which is supplied to the electro-chromatic layer (3-7) is generated in the photo-electric layer (9-11).

Hinge arrangement for attaching hinged parts

Abstract: In a hinge (4) between a fixed part (3) and a movable part (1), the pivotable hinge part (6) has a guide device (7) by means of which the movable part can be fixed on the hinge in a desired position relative to this and the fixed part. The movable part can then be detached from the hinge together with the guide device and can then, by means of the guide device, be guided back to the previous position when remounting takes place.

Arrangement for controlling a hydraulically operated friction disc clutch with diaphragm spring

Abstract: The invention relates to an arrangement for automatic control of a hydraulically operated friction disc clutch (60) with diaphragm spring (64) The hydraulic operating unit comprises a hydraulic cylinder which, by acting on the diaphragm spring (64), disengages the friction disc clutch In order to obtain a hydraulic operating unit in which the regulating pressure is proportional to the disengagement degree of the clutch, the hydraulic cylinder comprises a proportionality-forming spring (13) which acts against the hydraulic cylinder piston (4) during the final part of the disengagement stroke of the piston In a system with master cylinder (1) and slave cylinder (61), where the slave cylinder acts on the diaphragm spring for disengagement of the friction disc clutch, the master cylinder is also provided with a pressure supply, compensating for wear of the discs, via a hydraulic channel (7) which is closed off at a predetermined regulating pressure level The invention permits a simplified system solution for an automated diaphragm spring clutch in a vehicle, where the clutch does not require any positional sensors, but the disengagement degree is given by the hydraulic regulating pressure

Tensioning arrangement for a power-transmitting element incorporated in a transmission

Abstract: A tensioning arrangement for a chain incorporated in a transmission and intended to be driven in an endless path. The tensioning arrangement comprises a spring element that acts on a piston to move it outwards to tension the chain when the transmission is not in operation. The tensioning arrangement is also designed with a space that is supplied with oil when the transmission is in operation, in which connection the oil imparts to the piston a limited inward movement to slacken the chain.

Protection device for sensor means

Abstract: A protection device for sensor means (1) in a vehicle (2) such as a missile is described. The protection device is characterized particularly by a support (3) attached in the vehicle with a first flange means (4) and a protecting cap (7) with a second flange means (8). A flexible tightening means (9) is arranged between the limiting surfaces (10, 11) of the flange means in such a manner that a substantially gastight space is created, partly limited by the cap (7) and in­cluding the sensor means (1). At least one attaching means (13, 14) is so formed and arranged, that a compressive force on the cap, generated by overpressure in the space (12), brings the cap (7) to perform a movement rela­tive to the sensor means (1) with a composant of movement in a direction away from the sensor means (1) and at least one compo­sant of movement perpendicular to said direction, before being released from the vehicle. The limiting surfaces (10, 11) of the flange means are mutually so formed and arranged, that said move­ment is made possible.

Differential with four pinion gears

Abstract: A differential with a housing (2) made in one piece, which housing has in its wall two large side openings (10), is normally designed with only two pinion gears (12a, 12b) mounted on a pinion gear shaft (14). According to the invention, bearing parts (25, 26) are positioned in the side openings (10) and form the bearing points (23, 24) for a second pinion gear shaft (15) with a further two pinion gears (13a, 13b).

Device for a launcher on air vehicle

Abstract: A device at a launcher at an air vehicle for detachably carrying and guiding a missile or the like is shown. The launcher comprises means for detachably carrying the missile and means for guiding the missile in the longitudinal direction of the launcher. The latter comprises a first profile element (2) secured in the launcher and a second profile element (4) secured in the missile, which profile elements are arranged to interact in order to admit a free mutual movement in the longitudinal direction of the launcher, while movement in lateral directions is limited. The device according to the invention is characterized particularly in that it comprises a profile plate (7) and a number of relatively thin shims (8), the profile plate (7) and shims (8) being arranged securable in the first profile element (2) to so limit by means of an appropriate number of shims (8) the mutual movement of the first (2) and the second (4) profile element in the load carrying direction across the longitudinal direction of the launcher that the required allowance between the profile elements (2, 4) for mutual movability of the profile elements in the longitudinal direction of the launcher is maintained.

Connection to a pressure vessel of composite material

Abstract: A connection to a pressure vessel of composite material wound about a body part (1) a so-called liner of thermoplast with an end part (3) provided with an axial internal bore (5). The connection is characterized particularly in that the liner (1) extends somewhat into the bore (5) and ends with a first seat (8) across the bore (5) and in that a connection tube (9) provided with a second seat (11) is fixed relative to the end part (3) so that said seats (8, 11) seal towards each other, preferably with a packing between them (13).
