Title: Layered spectacle frame construction and mfr. - two plastic laminates are bonded and compressed onto fabric or film central layer before concave profile is machined on face
Inventor: SCHNEIDER DIETRICH
IPC: B29D12/02
Filed: 1989-10-24
Abstract: A process is described for production of spectacle frames (1) comprising two laminates (2,3) of transparent polymethylmethacrylate and an intervening layer of printed fabric of film (4). Initially the plastic laminates (2,3) are ground and polished on the sides to face the intervening layer (4). The intervening layer (4) is soaked in adhesive before application to the first (2) of the plastic laminates. A flattening operation on the intervening layer (4) is followed by application of the second laminate (3) and compression of the frame structure (1) at a given temp. and pressure. The frame (1) is then machined to concave profile on the inner side from one edge to the other. USE/ADVANTAGE - The design of the spectacle frame enables the patterned intervening layer to stand out. Patterns can be varied according to fashion.

Title: Method for joining and gluing veneer sections - has veneer sections with scarfed edges aligned to edge of veneer strip
Inventor: WAGNER ERICH
IPC: B27D1/10
Filed: 1990-04-14
Abstract: In the method for joining and gluing together scarfed sections of veneer, the veneer sections with their scarfed edge to be glued are aligned to the scarfed rear edge of the veneer strip. Without touching the rear scarf of the veneer strip the sections are moved transversely until the scarfed edges to be glued overlap precisely. They are then pressed together and hot-glued.

Patent DE-4020238-A1 (DE)
Inventor: LANG ARMIN
IPC: B62D5/30
Filed: 1990-06-26
Abstract: In a servo-steering system for motor vehicles with a reaction which varies with the speed of the vehicle, the reaction is controlled by an electronic control unit (5). Here there is a pilot lamp (8) which indicates the lack of a tachometer signal when the vehicle is started. The pilot lamp is not extinguished until the electronic control unit (5) recognises and indicates a movement of the vehicle through a tachometer signal. The illumination of the pilot lamp (8) warns the driver of possible danger which may arise through the fact that the steering remains light even at higher speeds.

Title: Method of clamping inserted carbide tips -  involves kinematic constraint of tip on localised areas to eliminate bending moments and breakage
Inventor: HAAS VON RAINER DIPL ING
IPC: B23B27/16
Filed: 1990-10-18
Abstract: The clamping method works on the principle that the tip should be supported only on carefully selected and localised areas, thus producing a kinematic constraint of the carbide tip. For example in a milling cutter with a square tip, the tip (20) is supported at the bottom face on a ball (11) recessed in the floor of the pocket. The tip has depressions in top and bottom faces whicha ct as seatings. Around the periphery the tip has re-entrant segments which provide line contact against locating pins (15). Clamping is done with a claw (30). A variety of configuraitons to suit tips of varying forms is possible. ADVANTAGE - Tip is relieved by bending moments and therefore not subject to breakage. A central fastening hole is not required. Clip flow is unimpeded. Careful finishing of pocket and tip abutment faces is not required. Tip is accurately located.

Patent DE-4105337-A1 (DE)
Inventor: FRICKER SIEGFRIED
IPC: B66C1/66
Filed: 1991-02-21
Abstract: The invention relates to flat steel concrete anchors for precast concrete parts, which customarily comprise a connecting region, lying close to the surface of the precast concrete part and having an opening for a hoist, and an anchoring region, lying deeper in the precast concrete part and possessing, at at least one point, portions which project from the plane of the flat steel and through which saddle-mounting faces directed substantially transversely with respect to the loading direction are formed for the concrete. These projecting portions are formed by hook-shaped bends which are at the same time intended to grip round reinforcement bars or secondary reinforcement bars. As a result of this shape, the flat steel concrete anchors are dependent, with respect to their position, on the direction of the secondary reinforcement bar, which can lead to problems in particular with very narrow concrete parts. The flat steel concrete anchor is to be provided in the anchoring region of the flat steel with an opening (5), beside which run lateral webs (6, 7) which are arched in opposite directions out of the plane of the flat steel by deformation. As a result of this shape, the opening is to have, in addition to the opening cross-section existing orthogonally to the flat steel plane, also an opening cross-section parallel to the flat steel plane.
