Abstract: The description relates to a multi-layer elastic surface panel and a process for producing it. The surface panel consists of at least one elastic layer of a uniform film or foil and at least one inelastic fibre or filament layer joined to the elastic layer at spaced points. With the elastic layer in the unstressed or partly tensioned state, the fibre or filament layer is laid in folds between the junction points and, with the elastic layer in the fully tensioned state, is flat. The inelastic fibre or filament layer consists of an originally smooth, unstretched or partly stretched material which is fused or adhesively secured to the unstressed elastic layer at the junction points and, after joint expansion therewith, assumes a permanent stretch.

Abstract: On décrit une installation pour un traitement thermique de matériaux en morceaux, tels que le calcaire, d'autres carbonates, des matières premières pour la fabrication du ciment et similaire. L'installation comporte une zone de préchauffage (1), un four (3) et une conduite (20) reliant la sortie (7) de la zone de préchauffage à l'entrée (13) du four. On prévoit un dispositif de séparation (21) qui fait partie de la conduite (20) et qui consiste en une conduite (21) permettant de faire circuler un flux de gaz de bas en haut. Ainsi, en entrant dans la conduite de séparation (21) par le haut, le matériau préchauffé va se disperser dans le flux de gaz venant à contre-courant, ce qui va provoquer la séparation des fines qui restent en suspension dans le gaz et sont évacuées par la sortie (25) aménagée à l'extrémité supérieure de la conduite, pendant que le matériau plus grossier tombe et arrive normalement par la conduite (20) à l'entrée (13) du four.

Granted: 2004-11-09
Abstract: Tooling for mounting angular sectors (8) of a distributor vane grid in a turbo aero engine casing (1), especially for a low pressure turbine. The mounting edge of the sectors (8) includes projections whose disposition requires a particular extremely precise movement to embody mounting. This is effected by using a set of tools including the support plates (58) of the sectors (8) suspended by connecting rods (60 and 61) from a circular plate (51) able to move vertically so as to start the engagement of the sectors (8) in their throat (84). The connecting rods (60 and 61) are disposed so as to enable the support (58) to move backward and be slanted and thus move back the projections of the uneven sectors (8) of the casing (1) and then engage them in the throat.

Filed: 1997-07-03
Granted: 2000-08-08
Abstract: A transmission is provided for converting rotary input into an oscillating output.  The transmission includes a housing with an input shaft and an output shaft, and a series of gears interconnecting the shafts.  The gears include a pair of rack gears on opposite sides of an output pinion mounted on the output shaft.  The rack gears are held in meshing engagement with the output pinion by a carrier which is mounted upon a floating bushing on the output shaft.

Patent CA-2214869-C (CA)
Inventor: WISHART ALEXANDER WALKER
IPC: H04J1/05
Filed: 1997-09-08
Granted: 2004-02-24
Abstract: The present invention is directed to a digital signal processing apparatus for frequency demultiplexing a wideband channel. The apparatus converts the data stream into parallel branches by means of a serial-to-parallel converter. The demultiplexing operation consists of a low pass and high pass fine filtering stage and a coarse filtering stage and is split among processors across the parallel branches. Wideband signals can be processed without expensive processors because of the slower rate in the parallel channels. The invention may also be used for the inverse function of multiplexing.

Abstract: A fluid distribution system is especially useful in agricultural apparatus for delivering liquid agricultural chemicals to agricultural fields. The system includes a flow divider with a cylindrical stator with a ring of collection chambers around the bottom of the stator and a rotor having a flow passage from the centre of the top end to the bottom end above the ring of collection chambers. The flow dividers may be cascaded to provide multiple outlets. The system may include plural liquid supplies and a mixer for mixing the liquids from the plural supplies to provide a desired blend upstream of the flow divider. It is preferred that the flow of each liquid can be varied to vary the blend. The system may also include a control that varies the blend according to requirements as distribution proceeds. This may include a recorded mapping of a field being treated and a position sensor, for example a global position sensor (GPS) for monitoring the position of the apparatus in the field. The liquid blend is then controlled according to the requirements of the field position.

Granted: 2007-09-18
Abstract: The object of the present invention is to concentrate the intake air flowing into a combustion chamber of an internal combustion engine near the ignition point of a spark plug, and to form a strong swirl effect in this area.   A projection 16 is formed on an end surface 5a of a piston 5. Projection 16 is positioned near an intake port disposed on one side of the upper surface of a combustion chamber. A cavity 17 is formed at a position closer to an exhaust port than projection 16. An ignition point of a spark plug is disposed above cavity 17. The intake port points toward the outer perimeter of the combustion chamber. The portion of projection 16 on piston end surface 5a that lies in the direction of the intake port is cut away. An intake flow passage 19 is formed on end surface 5a of piston 5, extending from a cut-away section 18 toward the exhaust port via the outer perimeter of piston end surface 5a. The end of intake flow passage 19 toward the exhaust port forms a cavity entry 20 through which intake air flows into the cavity 17.  The intake air entering the combustion chamber from the intake port goes through cut-away section 18 of projection 16, through the outer perimeter portion of piston end surface 5a, and into cavity 17 from entry 20 toward the exhaust port. A  swirling effect is formed in cavity 17.
