Abstract: The present invention relates to liposomal pharmaceutical preparations which include active agents such as antiseptic agents, wound-healing agents, or combinations thereof, useful in the treatment of external wounds. The active agents are encapsulated in liposomes, and the liposomes are incorporated in pharmaceutical preparations such as liquids, ointments, gels, lotions, or creams capable of delivering the active agents to external wound sites. The invention further relates to methods of preparation of the liposomes and the pharmaceutical preparations, and to methods of treatment of external wounds and ophthalmic infections.

Abstract: An air filtration system for a vehicle cab has an air recirculation circuit which includes an air recirculation blower arranged in an air recirculation channel system in order to draw air from the cab interior and to blow it back into the cab interior. An air recirculation filter is arranged in the air recirculation flow. In order to reliably avoid contamination of the cab interior during filter changes, the air recirculation filter is located in a portion of an outer wall of the cab roof behind a cover. The cover covers the air recirculation channel system hermetically from the cab exterior. When the cover is opened, the air recirculation filter is accessible from the outside.

Abstract: A transmission shift lever assembly has a manually operated shift lever that can be moved in a longitudinal direction and in a transverse direction. The shift lever operates upon transmitting elements in order to transmit information to the vehicle gearbox or a gearbox control corresponding to the movement of the lever. The shift lever is coupled to a retainer, and a plurality of arms form four-bar linkages which couple the retainer to housing members so that the lever pivots about a virtual pivot axis which is repositioned remote from the lever, and so that the shift lever moves with little tilting motion.

Abstract: A shift mechanism for motor vehicle transmissions having a selector lever (14) supported in bearings in a housing (10) that can be pivoted about a transverse axle (24) in longitudinal direction and about a longitudinal axle (50) in the transverse direction. At the selector lever (14) or at components (26, 82) moving with the selector lever (14) on the one hand and on components (96, 100) fixed to the housing on the other hand, position indicating elements (128, 130) or sensors (102-114, 120-126) are arranged in such a way that the sensors (102-114, 120-126) respond upon the approach to position indicating elements (128, 130) and transmit signals to a transmission control arrangement corresponding to the pivoted position of the selector lever (14).

Abstract: An actuator/sensor assembly is mounted on a housing of an operating handle. The assembly includes a sensor with a sensor casing, from which protrudes a rotatable sensor shaft. The sensor casing includes a threaded section which extends concentric to the sensor shaft and which is inserted into an opening in the housing. A bearing member is screwed onto the threaded section to clamp the housing between the sensor casing and the bearing member and fix the sensor to the housing. The actuator, such as a control knob, is coupled to the sensor shaft by a coupler. The actuator is rotatably supported on the bearing member and consequently on the housing. Transverse forces acting upon the knob are absorbed by the bearing member and transmitted to the housing so that the sensor shaft is not subject to lateral forces from the knob. The coupler transmits rotational movements from the knob to the sensor shaft and allows for misalignment between the knob and the sensor shaft.

Abstract: A control device for an infinitely variable transmission includes a control lever that is movable along a guide slot and whose position within the slot indicates the commanded speed and direction. The control lever is moved forward from a zero speed position to a maximum forward speed position. Between the zero speed position and maximum forward speed position is a set point position corresponding to a set point speed. A set speed adjuster, such as a potentiometer, enables the operator to adjust the set point speed that is commanded when the control lever is placed in the set point position. The speed for positions of the control lever between the zero and the set point positions varies proportionally between zero and the set point speed. Likewise, the speed for positions of the control lever between the set point position and the maximum forward speed position varies proportionally between the set point speed and the maximum forward speed.

Abstract: A manually controlled operating lever for a vehicle operator's platform has an electrical actuation transducer for transmitting control signals to a working function as a function of the pivoting of the lever and/or as a function of the actuation of at least one actuation element arranged on the lever. In order to avoid an undesired release of working functions, a manually operated activating element is mounted near a hand grip of the lever, and is coupled to a switching element which operates to activate the actuation transducer for the transmission of control signals as a function of actuation of the activating element.
