Abstract: A shock absorber is provided that includes a shock absorber body defining a cavity that is at least partially filled with hydraulic fluid. A piston is slidably arranged within the body and separates the cavity into rebound and compression fluid chambers. A rod is secured to the piston and includes first and second portions that are respectively adjacent to the rebound and compression chambers. A fluid passageway extends between the first and second portions to fluidly connect the rebound and compression chambers. In this manner, fluid is permitted to flow through the rod to provide damping characteristics in addition to those damping characteristics typically provided by the piston. A valve assembly, which may include a one-way check valve, is arranged within the passageway for controlling the flow of fluid between the rebound and compression chambers through the passageway. Preferably, the rod includes a longitudinal bore having an adjustable plunger arranged therein. The plunger may be adjusted by a knob to move the plunger to block at least a portion of the passageway to further control the flow of hydraulic fluid through the passageway.

Title: Method and device for accepting articles in the form of sheet-type material
Inventor: SCHELLING DIRK
IPC: G07D13/00
Filed: 2001-10-01
Granted: 2007-04-10
Abstract: The present invention relates to a method and apparatus for accepting sheet material, in particular papers of value such as bank notes, checks, etc., whereby different groups of sheet material are successively accepted and stored. In a known method and corresponding apparatus for accepting groups of sheet material such as bank notes, the bank notes coming from a deliverer are checked and stored in a storage container in the order of their input. Thus it is not always recognizable without doubt subsequently, e.g. in cases of malfunction, which deliverer certain bank notes come from.  The present invention starts out from the consideration that each group of sheet material is assigned at least one separation means and the separation means are stored at least partly together with the associated group of sheet material for separating the associated group of sheet material from other groups of sheet material.

Abstract: A monolithic integrated circuit amplifier has a gain stage (202) and a buffer stage (210). The buffer stage includes an output stage and two separate voltage supplies (+Vlo, +Vhi), the second of which has a greater magnitude than the first. Switching circuitry is included that is connected to the output stage via a regulator bus. When an output demand voltage is less than a switch-over threshold, current to the output stage is provided substantially from the first voltage supply (+Vlo); when the output demand voltage is greater than the awitch-over threshold, current to the output stage is provided substantially from the second voltage supply (+Vhi). Collector voltage at the output stage is dynamically controlled to be greater than the emitter voltage by a difference voltage that increases proportionally as output voltage increases above the switch-over threshold. This difference voltage is commonly reffered to as "headroom". The dynamic headroom control circuitry preferably includes circuitry for predicably setting and controlling the headroom voltage at switch-over and smoothly increasing the headroom voltage up to maximum output voltage.
