Patent DE-4200061-A1 (DE)
Inventor: ERBAN ANDREAS DIPL ING
IPC: B62D6/00
Filed: 1992-01-03
Abstract: In a method of determining the transverse velocity Vy and/or the drift angle  beta  of a steered vehicle, input values of the steering angle  delta v (and possibly a rear steering angle), the vehicle longitudinal velocity vx, yaw angular velocity  omega , transverse acceleration ax and wheel velocities are required for a mathematical model. A second version (Fig 5) uses measured or estimated brake pressures instead of a measured value of transverse acceleration. The determined velocity/angle may be used to assess or control the stability of the vehicle. The method requires fewer expensive sensors than the prior art. <IMAGE>

Title: Winding machine - has initial reserve winding mechanism to secure yarn end for creeling operation
Inventor: ENGER JUERGEN
IPC: B65H54/34
Filed: 1992-04-08
Abstract: When reserve winding on the tube of a reel, before main winding commecnes, the reserve takes the initial length of yarn and covers it, to hold id down, then separates the free end. Pref. the yarn (10) is wound from a package and through yarn guides to the cross winder. The position is controlled by the guide (13) as reserve winding commences. The yarn end enters a notch in the disc (7), and is drawn by suction into the passage (49). The sensor (S) determines when yarn is present. The angle of the yarn (22') is arranged to be along the length of the tube, and at right angles to the direction of wind, and is held in this position until further winding covers it (28). The mechanism (30) has a cutter blade, which trims off the loose end of yarn, and this is carried away in the suction passage. The reserve winding secures the end (22'), which is available on the reel for creeling purposes. ADVANTAGE - The free end is always available, but does not become trapped in transit or in winding. It is securely fastened by the reserve winding.

Title: Electroplating or electrolysis DC supply - has separately locatable voltage regulating unit and bath current unit
Inventor: HUEBEL EGON
IPC: H02P13/06
Filed: 1992-04-29
Abstract: Electroplating or electrolysis d.c. supply arrangements are claimed, in which a variable output alternating voltage is adjusted by a regulator (regulating transformer or thyristor regulator) forming the a.c. side and is fed to the current transformer of the d.c. side. In one arrangement, the regulator is designed and located as a separate regulating unit, the current transformer and its rectifying diodes are designed and located as a separate bath current unit, and medium voltage lines are connected between the regulating unit output and the bath current unit input for power transmission. USE/ADVANTAGE - The d.c. supplies are useful for electroplating and other electrolytic (e.g. metal electrowinning) processes. The rectifying arrangement is divided into two separate and separately locatable units (i.e. the regulating unit and the bath current unit) so that the bath current unit can be located at the electrolysis cell where it takes up less space and allows short busbars or cables to be used.

Title: Front-end structure for a motor vehicle
Inventor: KLIE WOLFGANG DIPL ING
IPC: B62D21/15
Filed: 1993-02-05
Abstract: In the case of known front-end structures in a vehicle end region, in which a cross-member is connected rigidly to one end of a longitudinal member, there is the risk that the impact forces, in particular in the event of collisions with only partial overlap, are transmitted, even when the accident is not at all severe, to that side of the front end which is remote from the impact, leading to an increase in the amount of damage. In the case of the novel front-end structure, the cross-member (2) is connected, in a manner which allows it to be deformed by rotation about a vehicle vertical axis (3), to the longitudinal member (1), preferably via a continuation (9) of the actual longitudinal member (1), the continuation widening in a funnel-shaped manner towards the end region (21) of the vehicle. With a front-end structure of this kind, in the event of collisions with little overlap and only minor damage, deformations are not passed on to that half of the front end which is remote from the impact without interfering with the transmission of tensile stresses and transverse forces in the direction of the vehicle vertical axis for ensuring the front-end rigidity in driving mode. Use in vehicle construction. <IMAGE>

Title: Machine-table clamp
Inventor: KLIMACH HORST
IPC: B23Q3/06
Filed: 1993-03-05
Abstract: A machine-table clamp for securing a workpiece in position on a machine table. The machine-table clamp comprises a housing, a pressure element rotatably mounted about an axis in the housing and having a pressure arm projecting from an opening in the housing and a rotary rim carrying the pressure arm, a pressure spindle mounted in the housing and engaging in a peripheral toothing section of the rotary rim, and dirt wipers which are arranged in the area of the opening, start from the transverse margins of the opening and in each case bear on a cylindrical surface section of the rotary rim coaxial to the rotation axis and lying in each case between an extension of the clamping arm and the toothing section. In order to improve this machine-table clamp in such a way that optimum sealing between the pressure element and the housing can be achieved in a simple manner from the production point of view, it is proposed that, starting from side edges of the opening, a gap extending between these side edges and the pressure element into the housing be closed by a collar which encloses the dirt wipers.

Title: Electromotor sliding contact with vibration damping - is formed from compressed powder with over compressed zone formed around end of conductor to hold fast against vibration
Inventor: DEBOVES JEAN-BERNARD
IPC: H01R43/12
Filed: 1993-04-30
Abstract: The sliding contact is formed by compressing an electrically conductive powder (1). This contains one end (2e) of an electric conductor (2) such as a wire, cable or flex.
