Title: Use of extracts of lamiaceae species for delaying color loss in irradiated meat
Inventor: ROBBINS KRISTEN
IPC: A23L13/40
Filed: 2003-11-12
Abstract: An extract of plants of Lamiaceae species delays color loss in irradiated meat. The rosemary extract is applied prior to treatment with ionizing radiation followed by packaging in a modified atmosphere and storage under lighted retail display or under dark conditions. Onset of color loss of irradiated meat kept either in no light or in lighted conditions occurred much later than in irradiated meat not treated with the rosemary extract. In addition to the improvement in red color retention under lighted display, development of malonaldehyde but not alkenals was delayed with treatment using the rosemary extract.

Title: Hydraulic oil well pump drive system
Inventor: STANLEY LLOYD
IPC: E21B17/00
Filed: 1993-03-01
Abstract: A hydraulic oil well pump drive system for driving an oil well sucker rod (not shown) includes a master piston positioned within a master cylinder for axial displacement between first and second ends of the master cylinder. The master piston has a piston drive rod which extends through one end of the master cylinder.  The drive rod is connected to a crankpin of an eccentric crank. The eccentric crank is driven at a constant rotational speed to reciprocate the master piston within the master cylinder at a sinusoidal rate. A center seal assembly divides the master cylinder into a working chamber and a pressure chamber in opposite ends of the master cylinder. Each respective chamber defines a fluid volume which varies with the displacement of the master piston. The master piston displacement creates a bi-directional flow of working fluid from the working chamber. A wellhead hydraulic assembly is operably connected to the oil well sucker rod and is in fluid communication with the master cylinder working chamber to receive the working fluid flow. The wellhead hydraulic assembly is responsive to the working fluid flow to reciprocate an oil well sucker rod at a rate which relates to the rate of master piston displacement. A gas accumulator is in fluid communication with the master cylinder pressure chamber to bias the master piston toward the master cylinder working end, providing an upward biasing force at the wellhead hydraulic assembly.

Patent CA-2461330-A1 (CA)
Title: Valve assembly
Inventor: WRIGLEY ANDREW NICHOLSON
IPC: F16K15/18
Filed: 2004-03-16
Abstract: A valve assembly is designed to avoid or minimise the effect of "compression setting" which occurs when valves control the flow of some hazardous and/or corrosive fluids, especially when at an elevated temperature. The valve assembly includes a valve stem having a head portion which engages with a valve seat in order to close and seal the valve and an elastically deformable portion. In order to allow fluid to flow through the valve, the elastically deformable portion of the valve stem is deformed to allow fluid to pass between the head portion and the valve seat. An additional biasing element such as a cylindrical or conical compression spring is provided to urge the head portion towards contact with the valve seat. In this way, should "compression setting" of the elastic portion of the valve stem take place, the additional spring will ensure that the valve head is still able to be engaged with the valve seat to thereby close the valve.

Abstract: En ce qui concerne la distribution du courrier, on sait que le distributeur, qu'il soit publique ou privé, a souvent a déployer des efforts considérables si cette dernière n'est pas déblayé ou inondé(été comme hiver). Le détenteur de la boîte à lettres n'a parfois pas les moyens de s'assurer que celle-ci est toujours en état  fonctionnelle  pour le distributeur de courrier. Dans la présente invention, la boîte à lettres est muni d'un mécanisme servant à  minimiser les efforts déployés par le distributeur de courrier et le détenteur de la boîte à  lettres. Un tel mécanisme consiste a munir la boite à lettres traditionnelle d'une poignée qui une fois actionnée permet à celle-ci d'avancer vers l'usager (environ 41 cm), d'ouvrir la porte et d'enclencher le drapeau avertisseur. Le mécanisme est monté sur un trépied qui permet un ajustement adéquat, solide et résistant, pour tout emplacement et tenant compte de l'irrégularité du sol.
