Patent number: 7460841Abstract: A circuit arrangement includes two adjustable amplification devices where the signal output of the first amplification device is connected to the signal input of the second amplification device. The first amplification device has a digital input for controlling its gain and the second amplification device has an input for controlling its gain. The input for gain control in the second amplification device is connected to the input for controlling the gain of the first amplification device via a means such that a change in the gain of the second amplification device in one direction is effected by a change in gain, brought about by means of the control, in the first amplification device in the opposite direction such that the total gain remains essentially the same.Type: GrantFiled: August 29, 2005Date of Patent: December 2, 2008Assignee: Infineon Technologies AGInventors: Frank Fischer, Horst Klein, Erwin Krug, Bernd Pflaum

Patent number: 5230404Abstract: For assembling hoistway or elevator shaft equipment, there is moved in vertical direction within the hoistway, an erection scaffolding comprising a first working platform, a second working platform, a third working platform and a fourth working platform. The first working platform is arranged at the lower end and the second working platform at the upper end of a elevator car support frame serving for the reception of the elevator cabin following completion of the erection operations. The erection scaffolding continues above the elevator car support frame with the third working platform and ends with the fourth working platform. A suspension tube, a lower deflecting roller and an upper deflecting roller serve as a suspension system for the elevator car support frame. The lower deflecting roller is arranged at the upper end of the suspension tube and the upper deflecting roller is arranged at an elevator hoistway support.Type: GrantFiled: February 28, 1992Date of Patent: July 27, 1993Assignee: Inventio AGInventor: Horst Klein

Patent number: 5228753Abstract: The present invention relates to a process for producing bristle materials suitable for inserting into toothbrushes and based on synthetic fibres which have been roughened on their surface by mechanical action, in particular by means of a blast apparatus, the roughening being accomplished on the endless fibre strand after stretching. Using these bristle materials, toothbrushes with an improved plaque-removing action can be produced.Type: GrantFiled: June 7, 1991Date of Patent: July 20, 1993Inventors: Horst Klein, Wolfgang Wiedemann, Hans Klinger

Patent number: 4942945Abstract: A brake cylinder, especially for rail vehicles, with a simple-acting linkage regulator for maintaining a uniform play between the brake surfaces. A nut that is disposed upon a threaded spindle is connected with first coupling surfaces that cooperate with second coupling surfaces disposed on the piston of the control or operating cylinder. A coupling element that is provided with the first coupling surfaces is further provided with a centrally disposed pin that is guided in the piston of the cylinder. A spring or other member that is under pressure is clamped onto the pin, with this member being secured in such a way that it cannot shift parallel to the axis of the pin nor can it rotate with the pin.Type: GrantFiled: August 26, 1988Date of Patent: July 24, 1990Assignee: Bergische Stahl-IndustrieInventors: Hans Rocholl, Horst Klein

Patent number: 4865166Abstract: An assembly and disassembly system for a spring of a brake actuation unit, in particular for rail vehicles including a fluid pressure cylinder and a piston slidable in the cylinder. A cylindrical nut member is provided having a tubular portion extending outwardly of the piston. An output head is connected to the tubular portion and includes an outer tubular portion extending towards the piston. A compression spring is provided disposed between the tubular portion of the cylindrical nut member and the outer tubular portion of the output head. A sleeve member is disposed between the spring and the outer tubular portion of the output head. This sleeve is provided with a slot which extends in an axial direction along the sleeve. The outer tubular portion includes an opening which may be aligned with the sleeve slot. A member such as a pin is provided which extends through the opening into the slot holding the sleeve and the outer tubular portion in a position engaged around the spring.Type: GrantFiled: June 19, 1987Date of Patent: September 12, 1989Assignee: Bergische Stahl-IndustrieInventors: Hans Rocholl, Horst Klein

Patent number: 4506400Abstract: The invention relates to an electrically operated toothbrush with oscillating motion, whose angle of oscillation can be adjusted.This is a easily achieved by the fact that the rotation of the electric motor producing the motion can be reversed by pole changing, and thereby the radius of the circular orbit of the bolt of a rotating shaft connected to the holder taking up the slip-on brush in a curve-like opening of a free disc is changed in its dimension, thus producing a variation of the angular deflection of the rotating shaft.Type: GrantFiled: November 30, 1983Date of Patent: March 26, 1985Assignee: Blendax-Werke R.
