Patent number: 4094073Abstract: An angle detector for determining a transducer's angular disposition to a capacitive pickup element. The transducer comprises a pendulum mounted inductive element moving past the capacitive pickup element. The capacitive pickup element divides the inductive element into two parts L.sub.1 and L.sub.2 which form the arms of one side of an a-c bridge. Two networks R.sub.1 and R.sub.2 having a plurality of binary weighted resistors and an equal number of digitally controlled switches for removing resistors from the networks form the arms of the other side of the a-c bridge. A binary counter, controlled by a phase detector, balances the bridge by adjusting the resistance of R.sub.1 and R.sub.2. The binary output of the counter is representative of the angle.Type: GrantFiled: November 10, 1976Date of Patent: June 13, 1978Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventor: Gilbert T.

Patent number: 4036388Abstract: The invention relates to the gasketting of cap blanks, to be closed onto bottles or other containers.The gaskets lie across the more or less flat top of the cap blank and the invention is concerned with the peripheral part of the gasket, i.e. that part which occupies the corner of the cap between the flat top and the skirt.One kind of closing operation in which a gasketted cap blank is closed onto a bottle neck involves so-called "reform", i.e. a lateral pinching action at the top of the skirt. To aid closing the bottle cap symmetrically on the bottle, the peripheral part of the gasket includes a relatively flat step portion.Type: GrantFiled: August 23, 1976Date of Patent: July 19, 1977Assignee: W.
