Patent CA-1043608-A (CA)
Inventor: COLLINS TERENCE J
IPC: G07F17/14
Filed: 1976-04-29
Granted: 1978-12-05
Abstract: ABSTRACT         A turnstile construction wherein arms normally block the path of movement of persons passing through the turnstile.          The arms are engaged when authorized passage is available, and this results in movement of the arms either by the force of the person passing through or in a motor-assisted fashion.  The head supporting the arms includes a control system including a drive gear tied to the arms for rotation during movement of the arms.  Rotatable locking members are connected to the drive gear, and engaging arms are movable into and out of engagement with the locking members for purposes of controlling use of the turnstile.  The engaging arms are normally controlled by the deposit of a proper fare whereby in the course of normal use, only persons paying a fare can pass through the turnstile.          When locked, the system automatically protects against breakaway even when an extreme load is applied.  A governor is included in the system in a fashion such that bi-directional speed con-trol is automatically provided in all modes of use.  The con-struction is designed for controlling the direction through which persons may pass; it can be efficiently set for free-wheeling in one direction, but will lock automatically in a po-sition so that improper use by partial movement of the turn-stile arms is prevented.  Also included is an automatic disen-gaging function to permit passage in both directions during emergencies and other circumstances where fares are not to be collected.

Title: Method of tensioning and joining a formed strap loop about a package
Inventor: LEMS PETER
IPC: B65B13/04
Filed: 1977-10-14
Granted: 1979-10-02
Abstract: ABSTRACT OF THE DISCLOSURE A method is disclosed for tensioning of a formed strap loop about a package and joining of the overlapping por-tions of the loop in a manner that improves the residual tension of the loop. The strap loop, in the region of the overlap, is twisted so that the sides of the strap in that region are dis-placed from the package surface and so that one of the edges of that region remains adjacent the package surface whereby the ten-sioned loop can be joined by friction fusion, formation of inter-locking slits, or application of an independent seal without having to insert an anvil or bearing member between the package and the loop and thus increasing the residual tension.  After the strap is restrained in the region where the strap free end overlaps a portion of the formed strap loop to prevent relative movement between the free end and overlapped portion, the package is encircled by the loop so that the strap is twisted in the balance of the loop relative to the restrained region.  The loop may be tensioned before or after twisting.  Regardless, in the twisted orientation, one of the two edges of the strap in the restrained region is adjacent the package while the other edge is spaced away from the package to expose, and provide a clear-ance area around, both sides of the overlapping strap portions in the region of restraint.  A joint connection or seal is then made between the overlapping portions of the loop by joint-forming mechanisms in the clearance area.  Finally, the trailing length, or standing portion, of strap is severed from the loop and the twisted strap is allowed to relax to a position flat against the package.
