Patent CA-1132052-A (CA)
Title: Blade structure for use in a windmill and method  of making said blade
Inventor: EGGERT WALTER S JR
IPC: F03D1/06
Filed: 1980-06-16
Granted: 1982-09-21
Abstract: ABSTRACT OF THE DISCLOSURE         A tapered blade for use in a windmill comprises a main spar or beam assembly having top and bottom flat sheets of metal.  Tapered angle strips are welded along the edges of the sheets.  With the sheets and strips twisted to the proper angles, they are joined together by shear web chan-nels welded along the edges of the strips.  Leading and trailing edge assem-blies, comprising primarily foam material, are bonded to the spar.  A fit-ting is provided to permit the blade to be attached to the mechanism to be driven on the windmill.  The generation of electrical energy by windmills is well known.  In such windmills, energy is generated by the wind being slowed down by propeller blades which are suitably connected to rotate and respond to wind movement.  Power from windmills has been used for pumping water on farms, for example, as well as furnishing electrical power for other purposes.  The number of blades used may vary in accordance with the particular application.  A propeller type two blade mill generally collects more power from the air than many multi-blade types.  This type is relatively light and has been used commercially in wind driven electric generating plants.

Abstract: ABSTRACT OF THE DISCLOSURE The dual element fuse of the present invention has at least one fusible element and at least one mass of heat softenable material; the fusible element will respond to a short circuit to fuse and thereby assure opening of the cirucit, whereas that mass of heat softenable material will respond to a long-continued relatively-low potentially-hurtful overcurrent to soften and thereby initiate opening of the circuit. The fuse preferably has a plurality of fusible elements and a plurality of masses of heat softenable material, and a connecting ring electrically interconnects one end of each of those fusible elements. In doing so, that connecting ring keeps any higher-than-normal-electrical-resistance connection between one of those fusible elements and an adjacent heat absorber from generating so much heat that it initiates premature softening of the mass of heat softenable material which is a part thereof.

Abstract: METHOD FOR LIMITING VOLTAGE ACROSS SERIES--CONNECTED THYRISTORS OF HIGH-VOLTAGE REC-TIFIER                  Abstract of the Disclosure The method according to the invention for limiting vol-tage across series-connected thyristors of a high-voltage rectifier as a voltage surge is applied thereto consists in limiting voltage across groups of series-connected thyris-tors with a specified number of thyristors in a group, which is selected to suit the voltage surge parameters. For this purpose, voltage is measured across the thyristor next to the point to which the voltage surge is applied, and then across the following thyristors. When voltage across the first thy-ristor raises to a preset level, total voltage across the thyristors is successively measured, starting from the first thyristor, until it reaches a level equal to the ratio bet-ween the voltage surge amplitude and the total number of series-connected thyristors of the rectifier, multiplied by the number of thyristors giving the preset total voltage level which corresponds to the number of thyristors in the group. Voltage across the group is limited to this level.

Abstract: Abstract The invention relates to a method and device for turning a log. In the method, the turning is carried out in two stages in such a way that the first stage comprises the turning of the log to a somewhat oblique position in relation to the transverse direction of two rollers (2) rotating in opposite directions, and the second stage comprises the turning of the log by means of the rollers in a controlled manner onto a conveyor (11), which is at the bottom of a trough (14). The device according to the invention has two rollers (2) rotating in opposite directions and, adjacent to each roller, a preferably V-shaped blade (3), which effects the first stage of the turning. The second stage of turning, effected by the rollers (2), is controlled, a factor which provides a considerable improvement in efficiency.
