Patent CA-2372621-A1 (CA)
Title: Vehicle axle
Inventor: BRITTON PHILLIP JOHN
IPC: B62D17/00
Filed: 2002-02-21
Abstract: The invention relates to vehicle axles for fixed lorries and trailer vehicles having a supplementary axle system that is self-steering. Self-steering axle systems are known where the wheels are located on a pivotally mounted axle allowing the wheels to turn freely to follow the steered wheels. Known systems are adequate when the vehicle is moving in a forward direction, but have serious operational difficulties when the vehicle is being reversed.  The object of the invention is to avoid said known difficulties, and the objective is met by a vehicle axle comprising a stub axle assembly mounted by a first pivot on a support, and the support being mounted on a second pivot on an axle beam, said support being provided with a means of causing it to pivot between two operational positions, and to hold the support in a required operational position, and said first and second pivots being disposed at a convergent angle whereby to set the first pivot at a first castor angle in one operational position, and at an equal and opposite second castor angle in the other operational position.

Title: Regulating device for gas burners
Inventor: VROLIJK ENNO
IPC: F23N1/02
Filed: 2000-05-09
Abstract: The invention relates to a regulating device for gas burners. Regulating devices for gas burners are used to supply a gas flow and a combustion air flow to a burner.

Abstract: Pendant le déparaffinage catalytique d'hydrocarbures paraffiniques, la réaction de déparaffinage catalytique exothermique est atténuée par la séparation et le refroidissement d'un déparaffinat lourd dont le point d'ébullition initial est d'au moins 800 ·F+, et par son recyclage par un retour dans la zone de déparaffinage sous forme de liquide de refroidissement. Ce déparaffinat lourd réagit très peu, sinon pas du tout, avec l'hydrogène dans la zone de déparaffinage. Ce procédé s'est révélé particulièrement utile pour déparaffiner des hydrocarbures hydro-isomérisés, synthétisés par procédé paraffinique Fischer-Tropsch.

Title: Process to manufacture high impact natural composites
Inventor: MUHAMMAD PERVAIZ
IPC: C08F255/02
Filed: 2002-10-26
Abstract: The use of natural fibers as reinforcing filler in thermoplastics is a relatively new innovation and has great potential to replace glass fiber products in building, consumer goods, furniture and automotive industry. Our published results demonstrated that laying natural fiber mat and polymer film in a definite pattern and orientation can enhance mechanical strength. In this invention, an unique process has been developed to manufacture high impact strength composite that contains loose natural fiber and/or a combination of loose natural fiber and natural fiber mat to develop green composites outstanding impact strength and other mechanical properties. Loose fibers used in this process can be obtained from agro-plant and wood. Mats, if used, can be obtained from similar sources. Polymer those are used include thermoplastic polyolefins (TPOs), acrylic and polyester films. This invention is specially useful for natural composites with natural fiber content above 40% by weight up to 93 wt% fiber. Film stacking and fiber spraying methods were used to construct sheet, laminates and thermoforming and compression molding were used to design a product. A range of impact strength was obtained which varies from 100 J/m to as high as 250 J/m with a significant increase in flexural and tensile strengths. Products having uniform density profiles yield maximum enhancement in impact properties.

Abstract: The capacitor according to the invention is wound from at least one film (1) comprising a carrier film (3) -serving as dielectric - with at least one conductor layer (4). It has an internal series circuit. The latter is brought about by the conductor layer (4) applied on the dielectric or the conductor layers being divided into sectors (4.1, 4.2) which are mutually arranged and, if appropriate, connected to one another in such a way that a plurality of series-connected elementary capacitors are formed. It is distinguished essentially by the fact that a current path structure is formed on the sectors, the conductor layer (4) having a high sheet resistance for the purpose of reducing breakdown-governed capacitance losses and the current paths (5, 6) of the current path structure having a significantly reduced sheet resistance for the purpose of reducing the total sheet resistance.
