Title: Paging system with local channel lists
Inventor: KING RANDOLPH E
IPC: H04W88/02
Filed: 1990-06-07
Granted: 2001-04-17
Abstract: A paging receiver is provided a list of alternative paging channels to which it can tune if the paging channel presently being received becomes unreliable. This list, and other lists used by paging receivers in other geographical areas, are disseminated by linked paging transmitters that broadcast identical paging signals throughout a large geographical area. When a paging receiver finds a channel carrying paging data it identifies which of the plurality of transmitted lists is appropriate for its use by finding the list that references the channel to which the receiver is presently tuned.  The channels referenced in the identified list are then stored in a memory and may be tuned if the existing paging signal is lost.  Data is desirably transmitted with the local channel lists to permit each paging receiver to locate the list relevant to its geographical area without examining each of the transmitted lists.

Patent CA-2083106-C (CA)
Title: Apparatus for wire-stitching multi-component printed products
Inventor: MEIER JACQUES
IPC: B42C1/00
Filed: 1992-11-17
Granted: 1996-09-17
Abstract: The stitching or stapling heads, which act together in a stitching zone (C) with the supports that carry printed products to be wire-stitched, have a circular orbit.  The stitching heads are guided so as to maintain their more or less vertical position during their orbit.  Within the stitching zone  (C),   each   stitching   head  is  thus approximately aligned with its respective support and is therefore in  the   preferred   position for driving the staples into the printed products.   When the stitching heads encounter the supports, they   are pushed back radially inward against the resistance of  compression springs.   This causes a slight flattening in the orbit of the stitching heads in the stitching zone (C) and slightly prolongs the time available for the stitching heads to act together with the  supports in the stitching process.
Patent CA-2083841-C (CA)
Inventor: LINZELL GEOFFREY ROBERT
IPC: B23K35/22
Filed: 1991-06-13
Granted: 2001-08-14
Abstract: The invention relates to a method of making what may for convenience be regarded as friction joints - that is to say, joints be-tween the touching surfaces of two parts that are held in contact (by a force as experienced in a light interference, not one sufficient to cause forging) and that would otherwise move laterally past one an-other parallel to the touching plane, the method involving some mini-mal initial lateral movement of the two surfaces sufficient to cause some asperity deformation, leading to welding and shearing under special conditions - the phenomenon of "galling" - but not sufficient to raise the bulk temperature of either to a level where bulk welding will occur. More specifically, the invention provides a method of sec-uring against lateral motion two bodies (12, 14) held in face-to-face (11, 12) asperity contact, thereby to make a join between the two bod-ies, in which method there is inserted into the interface between the two bodies a material (15) that on minimal initial lateral relative mo-tion of the two surfaces promotes rapid but controllable "galling" (16) between the two surfaces, this galling binding the surfaces against further such motion.

Patent CA-2099149-C (CA)
Inventor: PARISI PAUL JOSEPH
IPC: B01D53/14
Filed: 1993-06-25
Granted: 1997-02-18
Abstract: Improved processes are disclosed for the removal of hydrogen sulfide from feed streams by conversion of hydrogen sulfide and sulfur dioxide to elemental sulfur and water, e.g. Claus process.  The feed stream of the present invention is divided into two split streams wherein one is incinerated to form sulfur dioxide in the presence of oxygen.  The sulfur dioxide is then separated from the water, nitrogen and other impurities and combined with the other split stream to form a reactor feed which is passed to a sulfur reaction zone for conversion to elemental sulfur.  Due to the rejection of water, nitrogen and other impurities from the reactor inlet stream, a higher concentration of hydrogen sulfide and sulfur dioxide can be achieved in the sulfur reaction zone.  As a result, the processes of the present invention can be used to increase the throughput of existing Claus process plants and reduce the size of new Claus process plants.

Granted: 1998-05-12
Abstract: The aim of this invention is to provide universal toilet fish which will be able to remove all the objects which might fall into the toilet. At present not all the objects may be removed from the toilet bowl by means of the flexible spring. Flexible spring has no means to attach itself to such an object like a small bottle or hockey puck. Therefore their removal becomes impossible. The only way of removing of such an object from the toilet bowl is to unscrew the toilet bowl, drain it from water, turn it upside down and shake hoping that the object will dislodge itself and fall off. With the old installations this often leads to damage to the tile file and damage to the lead connecting pipe increasing substantialy thecost of the repair. Universal toilet fish solves this problem. At the end of theflexible spring there is an inflatable baloon attached. This baloon is protected by the plastic cone which also facilitates its introduction into the toilet bowl. This baloon has a plastic pumping line which is lead in the center of the flexible spring to the crank of the flexible spring. On the crank this line is equipped with thebicycle valve. After the introduction of thus equipped flexible spring into the toilet bowl, the baloon must be inflated with the bicycle pump. The baloon expands closing the toilet bowl space chamber. By carefully withdrawing the flexible spring from the toilet bowl we remove all the objects trapped before the inflated baloon.
