IPC: E04D1/20
Filed: 2011-01-10
Abstract: The proposed technique of belt saw use is intended for use in woodworking, in particular for roof cladding or outer wall siding bevel boards cutting-out of wooden stuff. The invention scope is to use belt saw, positioned at certain angle against longitudinal fibers of the wooden stuff, preferably from 0 to 17 degrees, for bevel boards cutting. To realise the proposed technique an additional attachment used for wooden stuff fastening and adjusting at required angle. It has been suggested two alternatives of the technique realisation: 1) feeding mechanism of wooden stuff with fixed stuff, advancing towards saw band; 2) band saw, installed in a frame, moving towards stationary wooden stuff feeding mechanism with fixed stuff. Proposed technique enhance appearance of the end product because, band saw leaves straight traces on sawn face, whereas disk saw used for the same operation leaves apparent arched traces on the end product sawn face.

Date Sep. 20, 1990.The present invention relates to a method to use an optical fibre as a sensor. The method involves designing an optical fibre to have a sensor area (12) where the external influence on the fibre that is to be measured, for example pressure or magnetic field, is freely able to influence the fibre. Coherent radiation is then transmitted through the sensor area in several modes. On the receiver side the radiation is split in a detector device (14) into two beams, each including the entire interference pattern created by the transmission in the fibre. After that the beams are plane-polarized in two different directions which are conducted to a signal processing device (9,90) which detects the amplitude and/or frequency content of each beam and from this forms a signal which is a measure of their amplitude and/or frequency relation, which in its turn is a measure of the external influence in the sensor area (12).
