Patent NO-179979-C (NO)
Inventor: AULBERS ANTONIUS PAULUS
IPC: E05B59/00
Filed: 1990-04-10
Abstract: An "electronic" lock has a thrower 5 for extending and retracting the bolt when turned by a key carrying a proper code. Turning of the thrower through a sufficient distance to shift the bolt is normally blocked by a dogging lever 20 with which the thrower lug 6 abuts. The thrower lug also sweeps a cam track 28 on a second lever 26 so as to pivot the latter during initial turning movement of the thrower away from its rest position. The second lever carries an electromagnet 30. While the electromagnet remains de-energized there is no interaction between the two levers so that the second lever 26 can pivot independently of the first 20 and turning of the thrower remains limited. When a correct key code is detected, however, the electromagnet is energized to hold the two levers together. Initial turning of the thrower thereby causes the second lever to carry the dogging lever away from its blocking position and thus free the thrower for 360 DEG  movement.

Filed: 1989-11-06
Granted: 1996-04-23
Abstract: Novel compositions of silicone/polyether block copolymers are provided which are useful as surfactants in several classes of polyurethane foam production.  While conventional copolymers have a polysiloxane backbone with pendant polyethers, the surfactants of the present invention are the reverse with siloxane pendants on a polyether chain.  These novel non-hydrolyzable polysiloxane polyoxyalkylene copolymers which are characterized by an "inverted" structure, i.e., polyoxyalkylene backbones with lateral and/or terminally pendant polysiloxanes, represent species that are of a narrow  molecular weight and compositional distribution  and are free of unreacted polyether or non-modified silicone oil diluent.  These surfactants are useful in various urethane foam systems and can also display aqueous wetting properties.

Title: Detection apparatus for paper build up on reel bar
Inventor: KREMAR DJURO
IPC: G01N21/84
Filed: 1990-05-31
Granted: 1998-12-29
Abstract: In a web reeling machine such as the reeling portion of a paper machine the successful introduction of a fresh reel bar to maintain the continuity of the reeling operation is dependent upon turn-up of the web onto the rotating reel bar followed by build-up of a roll on the reel.  The end of a bifurcated fiber optic cable is positioned adjacent the jaw clamps that retain the stationary end bearings of the reel bar so as to provide an indication of the occurrence of successful turn-up by  detecting  a persevering  change  in the clamp/bearing relationship due to roll growth.  The other end of the bifurcated cable is connected to an light emitter and a light detector.  The light emitter generates  a  light signal along the bifurcated fiber optic cable towards a light guide path in a jaw clamp so that the light signal passes through the light guide path.  When the jaw clamp moves, the light guide path moves and the jaw clamp reflects the light signal back toward the bifurcated fiber optic cable which transmits the reflected signal to a light detector which detects the change in reel bar location due to roll growth.  The system can tolerate motion inconsistencies caused by reel bar bounce, due to a rough turn-up of the web.
