Patent DE-3907144-A1 (DE)
Inventor: PILLER HELLMUT
IPC: E04D15/04
Filed: 1989-03-06
Abstract: Process for reversibly fastening webs of large surface area to backings, in which the webs are firmly bonded or welded to the backing. The webs, which are coated with a hot-melt adhesive or heat-sealable material in which finely divided electrically conductive material is incorporated, are irradiated with electromagnetic waves with a wavelength in the range 2 to 300 GHz. This process is reversible, i.e., the fastening can be undone by further irradiation. The process can be used to fasten floor coverings to floors or roof panels to roofs, for surfacing or repairing roads with tar and bitumen and in dam building to construct watertight walls. Also described are devices for implementing the process, which consist of a mobile frame (1) with one or more pressure rollers (8), a microwave generator (2), a hollow conductor (3) which bundles the waves and directs the beams through a radiation chamber (4) onto a backing (5). This device can also be designed so that the radiation chamber (4) is replaced by metal or metal alloy guide rails (6) which project from the hollow conductor (3) and open into irradiation channels (7) arranged parallel to the backing.

Title: Force measurement during ultrasonic welding - using piezoceramic sensor between two plates connected to moving tool, allowing calculation of exact force between two welded components
Inventor: HAMMERL HEINZ
IPC: B23K20/10
Filed: 1989-06-30
Abstract: In ultrasonic welding equipment the sonotrode and the anvil are moved towards each other by pneumatic or hydraulic means. The speed of movement of the sonotrode towards the anvil can be reduced by a damper. A force measurement system determines the forces acting on the damper. In a new method of force measurement the measuring system is disconnected from the forces in the drive system and is connected only to the moving tool. Only the forces imparted between the components to be welded is recorded. The measuring system is located between two plates which are rigidly connected. The measuring sensor is only connected to one of the two plates. USE/ADVANTAGE - For welding two components, which can be plastic or metal, by the ultrasonic method. The measuring system determines only the forces between the components. The forces of the return springs and the damper are eliminated.

Title: Hand tool having drive means with lubricant - comprising gears which accelerate froth formation and lubricant controlling froth build-up
Inventor: BERGER GUENTHER
IPC: F16N15/00
Filed: 1990-02-03
Abstract: This manual machine-tool for drilling etc. is driven by a high-speed electric motor through gearing which contains a lubricant that wets, in particular, those parts of the gearing that mesh. The lubricant can be caused to foam by special additives. A number of variants are claimed for the lubricant and foam arrangements. USE/ADVANTAGE - The tool needs little lubricant, uses little energy, and is of comparatively low weight, low noise-emission, and long life. Expensive and environmentally harmful additives for the lubricant are not required. Instead of action being taken to inhibit foaming (as in other machines), foaming is assisted both by the gearing design and by the lubricant composition. This use of foaming can also be applied to larger machines.
