Title: Line tie assembly with captured cushioning pad
Inventor: WEIR JAMES A
IPC: H01B17/22
Filed: 1987-12-30
Granted: 1991-10-15
Abstract: Abstract of the Disclosure A line tie assembly for securing an elongated line conductor to a line support insulator includes a pair of single-strand line tie components.  The line tie components each have a pair of leg portions with helical preformed configurations and a generally U-shaped bight portion integrally interconnecting the leg portions.  A generally flat flexible cushioning pad composed of resilient material is pivotally connected to and extends between the bight portions of the line tie components.  The bight portions of the respective line tie components hook about a reduced diameter neck portion of the insulator on opposite sides thereof.  The leg portions wrap about respective adjacent portions of the line conductor on opposite sides of the insulator for securing the line conductor to the insulator.  The cushioning pad is placed between the conductor and a groove in the head portion of the insulator in which the conductor will be retained by the line tie assembly. The cushioning pad has a pair of opposing tabs to releasably attach the pad to the bight portions of the line tie components such that the pad extends therebetween in a captured relationship.

Title: Safety brake mechanism
Inventor: SALMELA GORDON O
IPC: B60T8/74
Filed: 1988-05-16
Granted: 1992-02-25
Abstract: Abstract of the Disclosure An acceleration-sensitive safety brake having two semi-cylindrical flyweights in a single plane, connected near the geometric center of their semi-circular cross-section to eccentric pivot pins protruding from a rotating hub for limit-ing the acceleration of an apparatus.  The flyweights are held in a centered position during normal operation by the force of a helical spring acting on split halves of semi-cylindrical cavities in each of the adjacent faces of the flyweights.  The flyweights are located in a cylindrical hole of a fixed housing which is concentric with the rotating hub.          Rapid angular acceleration of the hub applies both a rotational and translational motion to the flyweights.  Whenever the pivot pins apply a force to the flyweights which is greater than the force exerted by the centering spring, the flyweights move in opposite directions, relative to each other, and push against the fixed housing creating a braking action.  The material chosen for the flyweights is hard rubber, and a pre-selected ratio of the flyweight radius to pivot pin eccentricity radius makes the mechanism self-locking as long as input torque remains applied to the hub.

Title: Container closure with a retractable turnspout
Inventor: THANISCH KLAUS
IPC: B65D47/20
Filed: 1988-07-26
Granted: 1993-01-19
Abstract: ABSTRACT            A closure of plastics material for containers for receiving and delivering liquids or pastes.   The closure has a retractable turnspout.  A plug for closing the container mouth has on its base an eccentrically disposed bush which rotatably carries a turret.  Together with a transversely projecting tube the turret forms the turnspout.  A liquid passage leads through the tube and turret and through the bush.  Between the tube and bush a tap is formed to shut off the liquid passage.  A cap engages over the plug and container mouth and is rotatable with respect to the plug.   By virtue of rotation of the cap the tube is passed outwardly through a lateral opening in the cap and withdrawn again  when  rotated  in  the  opposite  direction.    A  shield upstanding from the plug base serves on the one hand to close the lateral opening in the cap, when in the closed position, and on the other hand to seal the outer end of the turnspout.  A wall on the cap base has engaging edges for pivoting the tube out and in.  For the purpose of further sealing, the turret can have in its interior a concentric hollow cylinder with a longitudinal slot for the passage of liquid and seal with respect to the wall of the bush when the tube is pivoted in.  A tamper indicator can be produced by a tongue which can be broken away and which sits in the lateral opening in the cap or closely outside this opening.
