Abstract: A linear motor includes a rotor (70) and a secondary member (80), wherein the secondary member (80) carries a cover for protection against mechanical damage, aggressive liquids etc. The cover (40) has low magnetizable material and is held in place by magnetic elements (30) of the secondary member. Thus, there is no need to secure the cover additionally by gluing etc and the cover can be easily replaced. The cover can be placed, preferably, as one piece upon the secondary member, which may be made of several secondary member elements, and carries a scale for controlling the position of the motor.

Abstract: A belt retractor for a vehicle safety belt comprises a belt spool, at least one locking member which at least largely prevents a belt spool rotation in the case of restraint, and a force limiter. The force limiter opposes a defined force to a rotation of the belt spool on unwinding of the safety belt. Furthermore, a blocking mechanism and an adjusting element for the blocking mechanism are provided. The blocking mechanism is able to be moved by the adjusting element at least partially toward a blocking position. In the blocking position, the blocking mechanism deactivates the force limiter. After a primary impact, a non-used force limiter is force transmitting, or the force limiter or force limiters are deactivated.

The module further comprises a gas bag arranged folded in the housing as well as at least one flap provided on the edge of the first side piece remote from the back, which flap is pivotally connected via a hinge with the first side piece. At least a major part of the flap, before an activation of the gas bag module, is arranged inside the housing and adjoins the inner face of the second side piece.

Abstract: The object in an arrangement for pumping an anisotropic laser crystal is to reduce the influence of the destruction limit of the laser crystal on increased pump power density and, in this connection, to achieve improved beam quality and increased efficiency of a diode-pumped solid state laser. At the same time, the pump volume and cross-sectional area are to be kept as small as possible along a length of the crystal corresponding at least approximately to the absorption length. The arrangement operates with an asymmetric pump beam whose pump beam cross section has different dimensions perpendicular to one another and with a laser beam cross section which is adapted to this asymmetry. That axis of the crystallographic axes of the anisotropic laser crystal in whose direction the highest value of the crystal breaking limit exists is oriented along the greatest temperature gradient in the direction of the smaller dimension of the pump beam cross section.

Abstract: A method of adjusting an electrical switch arrangement comprising a pair of electrical contact members to a predetermined contact spacing is suggested. A first one of the contact members is associated with a first contact carrier and a second one of the contact members is associated with a second contact carrier. The first and second contact members are normally spaced from each other by the predetermined contact distance and are movable relative to each other across the contact distance. At least one of the contact members is displaceably held on the associated contact carrier. The contact carriers are moved towards each other across the predetermined contact distance. The one of the contact members is displaced relative to the associated contact carrier into physical contact with the other of the contact members. The one contact member is fixed in position on the associated contact member while physically contacting the other of the contact members.

Abstract: The rotary housing of a hydrokinetic torque converter, which can be utilized in the power train of a motor vehicle—for example, in conjunction with a continuously variable transmission—contains a torque monitoring device which is installed in such a way that it does not take up any, or any appreciable, additional space, especially in the axial direction of the housing. The torque monitoring device can serve to transmit torque between the lockup clutch and the output element of the torque converter. Additional features reside in the provision, configuration and manner of mounting of an auxiliary mass, and in the provision of a member for centering the piston of the lockup clutch in the housing as well as a member for centering the housing on the output element of a prime mover.

Abstract: The invention proposes a contact connection for sound reproduction devices according to the flexural wave principle. Since the drive systems 21 of such installations require high current intensities and such current intensities could only be properly transmitted by massive contact connections which however hinder the flexural wave propagation, the object of the invention is to propose a contact connection which eliminates the problems of the state of the art, and which is also very easy to implement. To that end it is proposed that at least one of the two cover layers 12 and/or the core layer 11 contain conductive areas 17 which are connected to the lines 32 of a sound signal source. It is particularly advantageous if the conductive areas 17 can be manufactured together with the components that are also used to manufacture the core layer 11.

A transfer corotron recharges the toner particles to a polarity for transfer to the carrier material at a transfer location. A first transfer mode provides for accumulating a plurality of toner images on the transfer band before transfer to the carrier material. A second transfer mode provides continuous transfer of the toner image to the carrier material.

Abstract: A semiautomatic control system or control method ensures a driving method which is as energy-saving as possible. In the system, there is both a) manual inputting of control data, for example a definition of a vehicle speed specified value, by the driver of the vehicle and b) automatic determination of the most energy-saving vehicle speed as a function of predefined peripheral conditions, for example a general travel schedule, the topology of a route, vehicle-specific peripheral conditions and the like. An inference system determines which of these two values is smaller, and the smaller value is used to make possible safe and at the same time energy-saving travel (or journey). A safety check of the manual travel speed input value and of the automatically determined travel speed specified value can also be performed to reliably prevent a maximum permissible travel speed value from being exceeded.
