Patent DE-19825698-A1 (DE)
Title: Belt grinder with contact wheel and belt guide rollers
Inventor: LEHR HANS
IPC: B24B21/12
Filed: 1998-06-09
Abstract: The feed position of the contact wheel (2) relative the work is controlled by a linear drive (12) used to move the wheel holder (11) along line (23) using two-setting power cylinder (8) drive and holder (11) so that the contact wheel bears on the abrasive belt (8) in one cylinder end setting and retracts in the other end setting.   This is assisted by a spring (21) located in the drive path between drive and holder so the spring yields against the force acting on the contact wheel (2).   The spring is sited between cylinder and holder and is designed as a pneumatic diaphragm cylinder.   The two rollers (4,5) straddling the belt run are fixed immovably in the machine frame (3) and an additional return roller (6) acts as a tensioner and moves relative to the frame (3) as dictated by a pneumatic spring having controllable backpressure.

Patent DE-19840950-A1 (DE)
Inventor: RUECKERT HANS
IPC: C23C14/48
Filed: 1998-09-08
Abstract: The invention relates to blades for cutting moving lines of material, especially for cutting lines of paper or cardboard, plastic films or metal foils. Known blades (1, 2) have a blade body (3) with a steel cutting edge (5). According to the invention, foreign ions are inserted between layers in the cutting edge (5) by means of a plasma-assisted process, the penetration depth being between 50  mu m and 500  mu m, preferably between 100  mu m and 200  mu m. The doping of foreign ions in the metal lattice produces an improvement in hardness which is optimal for cutting without causing the steel to become too brittle. The inventive blades therefore have a long service life, even when used to cut lines of paper or cardboard, which can be abrasive, and are still economical to produce.

Filed: 1999-03-10
Abstract: The aim of the invention is to improve a compressor comprising a spiral compressor, which has a first compressor body and a second compressor body, an actuating device equipped with a motor, and a driving unit, which contains a driver that rotates on a driver path and a driver seat that is rotatably mounted on the second compressor body, whereby the driver seat can move in a radial direction relative to the center axis, with a radial degree of freedom with regard to the driver. In order to improve a compressor of this type such that the driving unit is provided with a simplest possible design, and such that it operates with the least amount of wear, the invention provides that the driver comprises a driver surface which is curved in a direction perpendicular to the center axis and which is convex in a direction of rotation. In addition, the invention provides that the driver seat comprises a driver surface which is concave in a direction of rotation, which faces the driver surface and which has a smaller curvature than that of the driver surface upon which the driver surface acts over a contact area by applying force. Additionally, the driver surface can move relative to the driver surface with a component which extends in a direction of the radial degree of freedom.
