The frequency of the AC signal used to detect the integrity or lack of same in a conveyor belt is reduced to be in the 25 KHz. to about less than 200 KHz. and most preferably in the 50 KHz. to 100 KHz. frequency range. When such AC signals are capacitively coupled to antennas carried by a conveyor belt past a rip detector station, the ratio of the magnitude of such signal relative to that of the c...

What is disclosed is platinum catalyzed mixtures of silicon hydride and CH2=CHSi-containing siloxanes which contain a platinum catalyst inhibitor and which may contain a reactive diluent to give prolonged resin working time and which do not give striations in the final cured resin product.

Condensation curable silicone release compositions comprised of a silanol functional base polymer, a crosslinker containing silanic hydrogen, a precious metal catalyst such as platinum or rhodium, an optional carboxylic ester inhibitor and silicone vinyl gum cure accelerators effective for allowing thermal cure at relatively lower temperatures while minimizing the necessity of excess metal catalys...

PURPOSE:To decrease light losses by formation of a main waveguide and a subwaveguide having a circular shape in section by irradiating the UV light propagated through an optical fiber of graded index type to a photosensitive resin coated on a glass substrate thereby curing the resin. CONSTITUTION:A glass substrate 6 is disposed between an optical fiber 1 and optical fibers 2, 3, and a photosensiti...

PURPOSE:To prevent a used film cassette in advance from being reused, by providing a hole fitting to the guide shaft of a cassette holding chamber, elastic clicks fixed to the inside of this fitting hole, and an engaging member to be engaged with the clicks. CONSTITUTION:A fitting hole 10 is provided almost in the center of a film feeding part 3, and plural elastic clicks 11 are arranged at equal ...

PURPOSE:To prevent reuse of a used film cassette in advance, by providing a hole fitting to the guide shaft of a cassette containing chamber provided in either side of a film winding part, and providing a container in the innermost part of this hole. CONSTITUTION:A fitting hole 10 is provided in parallel to a film winding shaft almost in the center of a film feeding part 3, and a container 12 for ...

PURPOSE:To prevent reuse of a used film cassette in advance, by providing an engaging member on the opening of a fitting hole provided to fit to the guide shaft of a cassette container in either of a film feeding part or a film winding part. CONSTITUTION:An unused film 2 is wound in a film container 9, and a fitting hole 10 is provided in the direction of film winding shaft almost in the center of...
