Patent DE-4201391-A1 (DE)
Inventor: EGGENSPERGER HEINZ DR
IPC: A01N43/50
Filed: 1992-01-21
Abstract: A stabilised aldehydic disinfectant and preservative, in particular based on glutaraldehyde, which contains imidazole and/or imidazole derivatives as stabiliser, is described.

Title: Safety lock for drill chuck - is pivoted in jaw guide sleeve and is forced by spring into engagement with teeth on chuck spindle body where cutting torque tends to reinforce locking action
Inventor: SIMON GUENTER
IPC: B23B31/12
Filed: 1992-03-06

Title: Needle-felt carpet - has thermoplastic offcuts as a base for the thread
Inventor: TESCH GUENTER
IPC: D04H1/46
Filed: 1992-05-26
Abstract: A process to manufacture a carpet of needlefelt, set on a base with a middle and top layer, which are needled together to form a three layer component. The middle layer consists of thermoplastic material. A distributor lays the thermo-plastic offcuts onto a conveyor. The plastic material may be uneven, irregularly shaped, embossed or bubble film. This may be heaped up to ten times the final thickness. There is a base sheet and a top sheet, with the plastic in between. The layers are needled with a carpet thread or carpet loop thread. This assembly is then taken through heat treatment pressure rollers, so that a compressed sheet results, with the partial melt of the thermo-plastic anchoring the thread to the interior. A top loop formation allows some of the fibre to be attached to the plastic melt to ensure they are retained to the structure. ADVANTAGE - The vol. consists of offcuts from converters after crinkling and embossing, and is a low cost item. No expensive latex is required. The material is easily needled. The synthetic material is hygienic, easily cleaned, and sound-proof. It is water-repellant.

Title: Vacuum cleaner head with turbine-driven rotating brushes - has safety device to reduce brush speed when head is lifted from surface
Inventor: WOERWAG PETER
IPC: A47L9/04
Filed: 1992-09-01
Abstract: A vacuum cleaner suction head has rotary brushes with bristles protruding through the bottom opening and an "air turbine" driving the brushes through a belt.

Title: Method and device for sharpening a circular saw blade
Inventor: EDEL WALTER
IPC: B23D63/00
Filed: 1993-05-19
Abstract: The invention relates to a method of sharpening a circular saw blade by means of a rotating grinding wheel, the circular saw blade having a marginal contour with cutting teeth following one another in the peripheral direction with predetermined pitch, and the grinding wheel and the circular saw blade mounted for sharpening being movable relative to one another in the radial direction of the circular saw blade and in its peripheral direction along a grinding path, the grinding path to be followed for the sharpening being made to approximately coincide with the marginal contour of the circular saw blade at the start of the grinding operation by relative orientation of grinding wheel and circular saw blade. In order to permit mechanical starting of the sharpening operation irrespective of the rotary position of the circular saw blade, provision is made for the marginal contour of the circular saw blade to be scanned by means of a sensor, in the course of which the radial distance of the sensor from the axis of rotation of the circular saw blade and its rotary position are adjusted repeatedly, and the output signals of the sensor which correspond to the positional adjustments are analyzed for a next positional adjustment until a selected point of the marginal contour and thus the position of the circular saw blade relative to the grinding wheel is established, whereupon the marginal contour is mechanically orientated to the grinding path, and the sharpening operation with predetermined stock removal is started.
