Inventor: ROBERT DIPL-ING DR HOEHN BERND
IPC: F16H61/662
Filed: 1984-02-03
Granted: 1985-09-19
Abstract: Continuously variable cone pulley transmission with a hydraulic control for adjusting the axially displaceable input and output pulley and with a device which influences the basic pressure of the hydraulic control as a function of the torque and has a displaceable piston which, on the fixed input or output pulley, delimits a hydraulic chamber, which controls an outflow opening in the hydraulic chamber and is rotationally connected to the corresponding shaft, with a supporting ring which is situated adjacent to the piston, is connected to the input or output pulley, is likewise arranged in displaceable fashion and acts on a clutch which connects the input or output pulley pair to the shaft, and with transmission elements, which roll on oblique ramps of the piston and of the supporting ring and, as the torque increases, bring about a displacement of the piston. To control the clutch, a reversing valve (44) is arranged in the feed line (42) leading to the hydraulic chamber (58), the said valve decoupling the hydraulic chamber (58) from the hydraulic control (control valve 22) when the clutch (70) is in the disengaged condition, and connects the hydraulic chamber (28) and the feed line (42a) on the control-valve side to the unpressurised return (47), while a first base pressure valve (45) operative when the reversing valve (44) is in the activated condition maintains a predetermined base pressure in the hydraulic control (Fig. 1). <IMAGE>

Title: Clamping device for use on machine tools
Inventor: HAKE FRIEDHELM
IPC: B25B5/10
Filed: 1986-02-06
Granted: 1987-10-01
Abstract: To clamp workpieces (3) and tools in automatic machine tools, only one drive member (9) in the form of a self-locking screw part is used to actuate the clamping member (12). A stop (18, 19) reaches here into the swivel path of the clamping member (12) so that the clamping member (12) performs first a swivel movement and then an axial movement and vice versa solely under the action of the drive member (9). This results in a considerably smaller space requirement in a cost-effective construction of the clamping device (2), and extremely short clamping times are achieved for both the swivelling and the clamping. <IMAGE>

Title: Noise protection covering for land traffic routes
IPC: E01F8/00
Filed: 1986-04-11
Granted: 1987-07-23
Abstract: The invention relates to a noise protection covering for wide land traffic routes which, in the centre, have an inaccessible separating strip. The covering is closed above the carriageways and possesses lamellar covering elements above the open edge regions to break the sound waves, these elements permitting non-dazzling illumination and sufficient ventilation. Instead of a central wall in the separating strip, which is very costly in the event of vehicle impact and whose subsequent restoration causes obstructions to traffic, an equivalent sound-insulating effect is obtained by a lowered central lamella.

Title: Method for transmitting-end bandwidth compression of an analog signal and for receiving-end expansion of the transmitted signal and a device to carry out the method
IPC: H04B1/66
Filed: 1988-03-07
Granted: 1989-09-28
Abstract: A method is devised in which an analog signal whose speech-band-limited bandwidth is compressed at the transmitting end to part of its bandwidth, preferably to half of its bandwidth, and the signal transmitted in compressed form is expanded at the receiving end to the limited full bandwidth. For transmitting-end compression, the bandwidth-limited analog input signal undergoes full-wave rectification, in parallel with which it is converted at each of its zero passages into square-wave pulses and simultaneously phase-shifted through 90@. The full-wave-rectified signal in unmodified form and in inverted form, half-frequency square-wave pulses and both the positive and negative components of the phase-rotated and subsequently rectified signal are then fed to a selection switching arrangement with a built-in approximation function; the amplitude of the output signal of the selection switching arrangement is dimensioned in such a way that, following low-pass filtering of the applied frequencies at half the bandwidth, its envelope has a sinusoidal shape at half the frequency. For receiving-end expansion, the signal transmitted in compressed form undergoes full-wave rectification, is then differentiated and a first low-pass filtering is carried out to correct its amplitude, followed by a further low-pass filtering to limit the frequencies to the specified bandwidth.

Title: Height-adjustment device for the panel of a tilt-and-slide roof or of a spoiler roof of vehicles
Inventor: STEMMER THOMAS
IPC: B60J7/043
Filed: 1993-08-14
Granted: 1994-09-22
Abstract: The invention relates to a tilt-and-slide roof with a height-adjustment device for the front edge of the panel, which device is spring-loaded. According to the invention, a pivoted lever, which is mounted on a front slide by means of a spindle, is pressed, by means of the spring, with a first shaped part, which is integrally formed on the lower side of the lever, into an adjustably mounted second shaped part which is fixed on the frame, and, as a result, a precisely defined position of the panel in the longitudinal direction of the vehicle is ensured during the height adjustment. The same spring furthermore presses the front edge of the panel upwards and, as a result, facilitates the height adjustment thereof. During the operation of the tilt-and-slide roof the engagement of the two shaped parts ensures, when the panel is being closed, a precisely defined closing position at all times irrespective of play or wear in the drive or mechanism.

Title: Potential distributor, in particular for fuse boxes in motor vehicles
Inventor: SCHALLER THOMAS
IPC: H01R31/02
Filed: 1994-04-21
Granted: 1995-04-13
Abstract: The invention has the object of a potential distributor which consists of a two-layer flat base rail having a plurality of flat plug tongues, which project from the base rail and are oriented transversely with respect to the course of the rail. Although the flat plug tongues are bent by stamping from the sheet-metal material of the two base rail layers, they are connected either to the upper or lower layer in an alternating sequence, however. In order to produce a reliable potential distributor conveniently and cost-effectively, it is proposed to produce the two layers of the base rail from the two folded limbs of a longitudinally folded integral original strip. The longitudinal fold line, which is located between the two folded limbs which are pressed flat against one another, produces a first longitudinal folded edge in the complete base rail. The original strip has edge parts on two mutually opposite strip edges, which edge parts are admittedly arranged only at specific points, but lie alternately with respect to one another. These edge parts have the particular object of producing a third layer of sheet-metal material in the base rail in certain sections. For this purpose, folds in the original strip are carried out on two parallel fold lines which lie parallel to the longitudinal fold line. Extensions of these edge parts are bent away and produce the flat plug tongues.
