Title: Initial power control of mobile station transmission in a mobile radiotelephone station
Inventor: ANDERSSON CLAES
IPC: H04B7/26
Filed: 1992-05-15
Abstract: ABSTRACT OF THE DISCLOSURE A mobile station is instructed to first transmit at relatively high sending power on a channel being assigned despite possible interference and is then instructed before a first time interval has elapsed to transmit at a more optimal power level to reduce interference. The power level on the channel is then periodically monitored at a second time interval greater than the first time interval. Momentarily increased interference is therefore tolerated in exchange for increased assurance of channel assignment. The interference is quickly reduced by implementing a fast power regulating function as compared to a slower ongoing channel power monitoring function.

Title: Incineration of waste gas containing toxic or other fumes in the form of liquid droplets
Inventor: GOSSELIN GERARD
IPC: F23G7/06
Filed: 1992-07-21
Abstract: A method for treating waste gases containing toxic or odorous vapors in the form of a mist of liquid droplets using a regenerative incinerator of a known structure to do so. In this method, the waste gases to be treated are passed through a mist separator device installed in the waste gas supply duct of the incinerator in order to capture and remove a sizeable portion or all of the supplied mist thereby reducing or eliminating the amount deposited in the incinerator. There is also proposed to raise the temperature of the incinerators sufficiently to cause all the liquid condensate to be evaporated immediately upon their admission into the working parts of the system. There is further proposed to effect the evaporation of the liquids deposited in the surfaces of the equipment and packing by purging the beds of packing at each cycle, with a gas stream heated to a temperature sufficient to cause the evaporation of all the liquid deposits. There is also proposed to effect the removal of solid deposits in the regenerators by a periodic combustion cycle.

Abstract: METHOD OF USING CYLINDRICAL CONVEYOR              ABSTRACT OF THE DISCLOSURE       A method of using a cylindrical conveyor whose conveyor belt is inscribed with plural shape-holding rollers to be held in a cylindrical form with overlapped side edges of the conveyor belt.  The cylindrical conveyor is driven in a shape having straight running portions and curved running portions to transfer a substance enclosed in the cylindrical conveyor belt.          A length of a surrounding contour line in cross-section of the conveyor belt around the substance to be transferred is always maintained substantially constant at any portions of the conveyor so that the overlapping width of side edges of the conveyor belt is always constant at the straight and curved running portions.   As a result, it is possible to completely prevent the substance to be transferred from penetrating between the side edges of the overlapping portion of the conveyor belt and hence from scattering around and falling out of the conveyor.

Abstract: CONCEPT DE PATINS DE HOCKEY A CONTROLE AMELIORE Les patins de hockey modernes sont conçus avec comme priorité la protection du pied. Toutefois, trop souvent voit-on des patins où cette recherche de protection élimine presque complètement la possibilité d'exécuter certains mouvements de patinage essentiels au hockey. En effet, des patins trop rigides rendent parfois le contrôle de ceux-ci quasi impossible. C'est afin d'en arriver à un compromis entre protection du pied et maniabilité du patin qu'a été développé le concept de patin de hockey à contrôle amélioré. Ce concept gravite autour d'une bottine faite de 2 pièces de cuir cousues ensemble à chaque extrémité du pied puis recouvertes dans un deuxième temps de composantes de protection. Ces pièces de cuir montent plus haut le long de la cheville que celles des bottines traditionnelles pour permettre la pleine utilisation de cette articulation dans le contrôle du patin. L'arche de la bottine est de plus accentué de sorte que le devant du pied se retrouve plus près de la surface glacée pour un contrôle et une puissance accrus. Sous la bottine, un support dessinant l'arche du pied sert de point d'ancrage pour les composantes de protection ainsi que de point d'attache pour le support de lame. La lame est dessinée de façon à présenter un rayon de courbure plus faible que les lames modernes, surtout au niveau du talon. La lame, plus longue que les lames populaires, excède les extrémités de la bottine pour offrir plus d'équilibre et une poussée accrue. Enfin, le support de lame, bien qu'il puisse varier en matériaux et en formes, assure un transfert de force plus efficace entre les points de force du pied (talon, plante et orteils) et la lame.

Title: Height adjustment system for vacuum cleaner
Inventor: STEPHENS PAUL D
IPC: A47L5/30
Filed: 1992-12-22
Abstract: HEIGHT ADJUSTMENT SYSTEM FOR VACUUM CLEANER   Abstract of the Disclosure A height adjustment system for an upright vacuum cleaner comprises a cam member with a cam surface.  The cam member is mounted within a base and includes rollers which facilitate the sliding lateral movement of the cam member within the base.  The rollers roll within a channel within the base.  Notches are formed in the side walls of the channel and receive a resiliently deformable indexing member which locates and fixes a cam follower at discrete points along the cam surface.  A secondary height adjustment means comprises a ledge located on a housing which is attached to a handle.  When the handle of the vacuum cleaner is rotated from a use position to an upright locked position, the ledge on the housing displaces a finger which pushes against a fulcrum plate attached to an axle connected to the front wheels of the vacuum cleaner. When the axle is so displaced, the front wheels swing downwardly, thereby raising the rotating brush above the floor surface so that the floor surface to be cleaned is not damaged while the vacuum remains stationary.
