Filed: 1990-12-21
Granted: 1997-03-25
Abstract: A binding machine, such as a strapping machine, for binding a bundle of newspapers or magazines by applying crossed straps around the bundle.  Means are provided for conveying the bundle into and from a strapping zone.  Means including a strapping head for each strap are provided for applying a transverse strap and a longitudinal strap around the bundle.  A transverse chute is provided, which receives the transverse strap, which guides the transverse strap around the bundle, and which releases the transverse strap when the transverse strap is applied.  A longitudinal chute is provided, which receives the longitudinal strap, which guides the longitudinal strap around the bundle, and which releases the longitudinal strap when the longitudinal strap is applied.  The transverse chute arches from a given side of the strapping zone to its other side.  The longitudinal chute arches from a given end of the strapping zone to its other end but is curved and twisted so as to be laterally displaced from the strapping zone at each such end.  Means are provided for deflecting the strap released by the longitudinal chute so as to center such strap.  Further, means are provided for supplying such a strap to the strapping head for the longitudinal strap, along with a curved and twisted chute for guiding such a strap between the longitudinal strap-supplying means and the longitudinal strap-applying means.  Each curved and twisted chute directs such a strap along a serpentine path.

Patent CA-2040493-C (CA)
Title: Electric connector terminal, primarily a so-called isdn-plug, and a method of manufacturing contact strips therefor
Inventor: KJELDAHL POUL
IPC: H01R13/26
Filed: 1991-04-15
Granted: 2001-01-02
Abstract: In certain connector plugs use is made of contact strips (13) mounted next to each other such that at one end they form exposed contact springs (8), while at their other ends they have a loop portion (14) provided with a V- or U-shaped recess (16) for connection with a connector wire. the dimensions are rather narrow, and there is hardly room for two such recesses in each loop portion. However, there is an expressed demand for connecting two wires to some of the contact strips, and according to the invention this is made possible by shaping each strip (13) with two loops (14) mutually spaced in the longitudinal direction of the strip, where there is better room than in the width or height direction. With conventional shaping technique it is difficult to provide two loops (14) on one contact strip (13), but the invention comprises a method, which makes this possible, viz. by arranging for an active feeding of strip material to the loop areas from both sides of each of these.
Patent CA-2043794-C (CA)
Title: Easy grip bottle
Inventor: ZOGG JON
IPC: B65D1/00
Filed: 1991-06-03
Granted: 2003-08-05
Abstract: The bottle has two essentially identical indentations on essentially opposite sides for gripping and manipulating the bottle. The indentation are designed to provide for the same gripping feel whether gripped front or the back. The indentations are also designed to accept a thumb and one to four fingers. The positive gripping with the same grip feel allows the bottle to be used in either hand. This decreases the number of times that a bottle must be handled during use. It also decreases the likelihood that the bottle will be dropped while being handled.

Title: High power electrical machinery
Inventor: LEUPOLD HERBERT A
IPC: H02K31/02
Filed: 1992-01-17
Granted: 2000-04-11
Abstract: An electrical machine having a stator formed from a pair of cup-shaped permanent magnets symmetrically disposed on opposite sides of a conductive, disk-shaped rotor. The magnets are polarized such that a portion of their external magnetic flux passes in one direction through a short peripheral gap formed by the magnets in which the periphery of the rotor is disposed. The remainder of the external magnetic flux substantially passes in the opposite direction through a cavity defined by the inner volume of the cup-shaped magnets. The inner portion of the disk-shaped rotor is disposed in this cavity. One embodiment of the invention implements the cup-shaped magnets with modified "magic spheres" mounted on either side of the conductive disk-shaped rotor. Other embodiments use a magnetic plate on one side of the disk-shaped rotor to act as a magnetic mirror for a cup-shaped magnet mounted on the other side of the rotor. In still another embodiment, the magnets are mounted as rotors while the conductive disk is the stator. The machine may be used as a homopolar generator or a homopolar motor,
