Patent CA-2590148-A1 (CA)
Inventor: ELMELUND JOERGEN
IPC: F16G13/20
Filed: 2005-06-15
Abstract: An articulated driving mechanism (2) is composed of several inflexible links (1, 1', 1", 79, 84) in succession, the links of each pair of adjacent links being interconnected by means of a link pin (16, 16', 16"), arranged in both the adjacent links in such a manner that the links are pivotal in relation to one another about the axis of the pin. The links of each pair of adjacent links are mutually displaceable in the transverse direction of the link pin between a first position, in which the adjacent links are pivotal in relation to one another about the axis of the link pin, and a second position, in which corresponding meshing surfaces of each adjacent link abut one another and lock against mutual pivoting of the adjacent links. The link pin is displaceable in an elongated hole (23, 82, 89) in at least one of the links.

Abstract: A constant flow regulator device for maintaining a constant flow of fluid when a variable fluid pressure is applied, comprising an inlet duct (506) for incoming fluid, a housing (500) , and a movable partition (502) facing the inlet duct and being subjected to an elastic force. A fluid passage (510) of variable cross section area is formed between the inlet duct and the movable partition. The housing and movable partition form an inner compartment (504) in fluid communication with the inlet duct for establishing a fluid pressure inside the inner compartment approximately equal to the fluid pressure in the inlet duct. The size of the movable partition is significantly greater than the size of the inlet duct such that, in use, the partition is moved towards the inlet duct against the elastic force when the fluid pressure in the inlet duct increases to reduce said fluid passage cross section area, and vice versa, thereby maintaining constant fluid flow.

Inventor: PAYNE DOUGLAS ALAN
IPC: G01T1/29
Filed: 2007-02-06
Abstract: In coded aperture imaging knowledge of the coded array pattern and its positional relation to the detector array is needed in order to be able to reconstruct the scene image. Usually a theoretical model of the coded array is used and the actual array needs to be aligned accurately with respect to the detector. The present invention uses a coded aperture imager to image a reference object (34) in the scene and uses the intensity pattern (40) on the detector array (30) to determine the decoding pattern corresponding to the coded aperture array (32). The reference object may be a point source in which case the pattern on the detector array may be used directly as the decoding pattern or it may be used to correct a theoretical pattern for any misalignment.

Filed: 2008-10-28
Abstract: An internal combustion engine with a plurality of cylinders operating in a four-stroke mode, with pistons moving with reciprocating motion, employs at least one holding tank shared among a plurality of cylinders, and wherein the holding tank conveys a pre-combustion gas (fuel-air mix in gasoline engines) from the cylinders via a return manifold for reinsertion into an intake manifold of the engine. Valving extracts a quantity of pre-combustion gas from a cylinder into the holding tank during a compression stroke for subsequent discharge into the return manifold to reduce the compression ratio to a value less than the expansion ratio.
