Title: Stringed instrument with resonator - has loosely attached resonance panel which enables wider frequency spectrum to be produced
Inventor: BECK MICHAEL
IPC: G10D1/08
Filed: 1991-07-05
Abstract: The stringed musical instrument has a frame (C) which supports the strings. The instrument has a resonance panel (a) which is attached to the body along only one edge (b). This method of supporting the resonance panel enables a wider frequency spectrum to be produced by the instrument. The vibration of the resonance panel is not restricted in the way in which a panel which forms a rigid part of the instrument would be restricted. The instrument thus produces lower bass notes and higher top notes. USE/ADVANTAGE - Stringed instrument with a wider frequency spectrum.

Inventor: SINGLER HANSPETER
IPC: D06B17/04
Filed: 1991-10-19
Abstract: Uneven number of floating rollers with parallel movement are between final roller of the mangle roller pair and the wound fabric batch with surface contact against each. The surfaces of the suspended floating rollers exceed the length of the fabric web so material follows a serpentine path between the rollers from the mangle to the wound batch. Pref. floating rollers has a torque drive to compensate for the draw forces exerted on the fabric at the floating rollers. The floating rollers are suspended parallel to each other from floating arms which are mounted to the machine frame. Three or five floating rollers are fitted to the assembly. Knitted piecegoods are held continuously flat from the final roller of the mangle over the surfaces of the floating rollers to the transfer point at the surface of the wound fabric bath. At the transfer point to the wound bath, the tendency of the fabric edges to roll inwards is directed radially inwards w.r.t. wound batch.

Patent DE-4200354-A1 (DE)
Inventor: KOCH KLAUS-UWE DR
IPC: C08K5/19
Filed: 1992-01-09
Abstract: 2.1. Poly(meth)acrylates which contain silanes as adhesion promoters (coupling agents) for bonding to, for example, silicate glass tend to yellow. The yellowing can be reduced by addition of UV absorbers or covered by appropriately coloured glass sheets, but this means that the corresponding systems can no longer be initiated by UV. In addition, such systems do not always have a sufficiently long shelf life. The novel silane-containing methacrylate resin composition therefore contains components which have a reduced tendency towards yellowing. 2.2. The novel composition contains 20-99.9% by weight of (meth)acrylic esters ((meth)acrylates), optionally further comonomers or polymers and plasticizers and 0.1-30% by weight of a silane. 100 parts by weight of this mixture are reacted with free-radical formers, Cu<2+> and a quaternary amine. The components can be stored and reacted in premixtures. 2.3. Preparation of laminated glass sheets.

Filed: 1992-03-16
Abstract: The present invention presents a displacement transducer which can be equipped both with an inductive (10) and with a capacitive (11) sensor.
