Patent DE-3906601-A1 (DE)
Title: Two-wheeler with a safety frame
Inventor: BUEHLER GEORG
IPC: B62K3/00
Filed: 1989-03-02
Abstract: The present invention relates to a new type of two-wheeled vehicle with a low-lying, laterally arranged frame made of profiled rails. These converge in an ascending manner at the front and bear the front-wheel steering head here. The frame is hence of a trough-shaped design. In its rear region it is connected to a roll bar which continues downwards over the profiled rails, the rear swinging fork being coupled to this extended portion. The profiled rails can extend rearwards beyond the roll bar where they converge. The rear-wheel suspension can be shielded here and a fairing attached. If an underbody damping for the rear wheel is selected the profiled rails can end at the roll bar. The advantage of the solution according to the invention consists in a simple construction which ensures good road safety whilst retaining the open-air character of two-wheeled vehicles; the construction can readily be transferred to vehicles driven by muscular power.

Title: Double-sided adhesive tape mfr. - has adhesive applied to one side and dried before carrier is deflected for coating on the other side followed by drying
Inventor: CZECH ZBIGNIEW DIPL CHEM DR
IPC: C09J7/20
Filed: 1990-06-07
Abstract: To produce a double-sided adhesive tape, with one or more layers of adhesive, after the adhesive mass has been applied to one side it is dried and the volatile components dispersed. After the tape has dried, its path is deflected to bring the coated side into contact with the deflection rollers and the other side is coated with the adhesive mass, and dried. Pref. the carrier, which is coated with the adhesive, remains as an integral component of the final double-side adhesive tape, and cannot be sepd. from the adhesive when in use. In another form, the adhesive is peeled from the carrier and, at the same time, the adhesive film without the carrier is covered by a cladding layer, where a non-stick carrier film is used which is recirculated for continual use in the process. After one side of the tape has been coated with the adhesive mass, it is covered by a non-stick film before the tape is deflected for coating on the other side. The tape material is produced in a continuous mfg. process, using an adhesive mass contg. water or a solvent or a crosslinking agent. The coated tape is given a final crosslinking, pref. using ultra-violet radiation. The process can be used for the application of different types of adhesive means. ADVANTAGE - The method prevents bubbles or other faults developing in the adhesive, and gives a cost-effective mfg. technique. (6pp Dwg.No.0/0)
