Title: Method for removing hydrogen sulphide from oil-containing water and equipment therefor
Inventor: H YVIK HENRIK
IPC: C02F3/10
Filed: 1993-10-27
Abstract: The invention relates to a method for removing hydrogen sulphide (H2S) from oil-containing water and equipement therefor. Oil-containing water and nitrate is conducted through a bioreactor to remove H2S. Nitrate is added to the oil-containing water in a dose ratio (sulphide: nitrate) of 1:10 to 1:40. The retention time in the reactor tank is for 10-60 minutes. After this treatment, purified water where >90 % of the H2S-amount is removed are bt out of the tank. The equipment for performing the above mentioned method, is based on a bioreactor having large density of denitrifying bacteria The reactor tank (1), is filled with carrying material providing large contact area Even distribution of oil-containing water and nitrate over the carrying material which already may be covered by septic mud, forms an active sulphide oxidizing biofilm having large surface. This biofilm makes an extremely effective equipment for removing sulphide from oil-containing water.

In a crushing apparatus according to the present invention, forces applied to the cantilevered swing jaw (17) are transferred via the bearing support (31, 41) to the main frame (3), rather than to the pivot axis (21) of the swing jaw (17).
Patent CA-2155806-A1 (CA)
Title: Lawn mower having improved deck height adjustment mechanism
Inventor: STRONG DAVID S
IPC: A01D34/74
Filed: 1995-08-10
Abstract: A lawn mower having a deck height adjustment mechanism for simultaneously adjusting a height of a deck of a lawn mower at all four wheels of the lawn mower by the use of a single hand of the operator.   The mechanism includes an index plate having a plurality of teeth thereon defining a plurality  of  deck height  positions,  and  therefore  a plurality of height positions of a cutting blade supported by the deck.   The index plate is fixedly secured to an offset rear axle.   An engaging plate having a pawl is coupled  to  an  actuating  member  which  is  slidably, vertically moveable relative to the deck when the operator grips the actuating member and pulls upwardly away from the deck, while resting a palm of the same hand on a palm rest portion of the mechanism.   A linkage member couples the index plate to a bracket of an offset front axle positioned at a front end of the deck.   The operator adjusts the height of the deck relative to a ground surface by pulling upwardly with the fingers of one hand on the actuating member, while resting the palm of the same hand on the palm rest.  This causes the engaging plate, and thus the pawl thereon, to be drawn out of engagement with the teeth of the index plate.  The operator, while holding the actuating member engaged,  may either pull upwardly with the same hand, thus raising the entire deck of the mower, or may urge the deck into a lower position.  Movement of the index plate causes a simultaneous rotational movement of the offset front axle.  Thus, all four corners of the deck are caused to  be  raised or  lowered simultaneously as  the operator either lifts or lowers the deck while engaging the actuation member.

Patent CA-2158410-A1 (CA)
Inventor: HABERSTROH JAMES A
IPC: B65B13/18
Filed: 1995-09-15
Abstract: A method and apparatus for feeding and tensioning a strap (12) in a power strapping machine (10). The apparatus includes a strap feeding mechanism (32, 34), a strap tensioning mechanism (42, 46), a pivoting roller carriage (50) pivoted by a feeding and tensioning cam (70), a strap overflow housing (110) for receiving a strap (12) that is prevented from properly feeding into a strap application assembly by an obstruction during feeding of the strap (12), and strap stretch-out housing (121) for receiving a strap (12) that is removed from the strap application assembly or the strap overflow housing (110) during tensioning of the strap (12). The pivoting roller carriage (50) first actuates the strap feeding mechanism (32, 34) to engage a portion of a strap (12) and feed it toward the strap application assembly where the strap is formed in a loop about a package. The strap feeding and tensioning mechanism actuates a gripper that secures an end of the strap. The pivoting roller carriage (50) then actuates the strap tensioning mechanism (42, 46) to engage a portion of the strap (12) and apply a tension to the looped strap. The strap (12) will be fully retracted from the strap application assembly by the strap tensioning mechanism (42, 46) if the strap (12) is not properly engaged by the gripper, and the strap (12) will then be directed into a strap stretch-out housing (121) where it will remain until the strap feeding mechanism (32, 34) again engages a portion of the strap (12) and re-feeds it. The weight and position of the strap (12) disposed in the strap stretch-out housing (121) prevents it from withdrawing entirely from the strap feeding mechanism (32, 34) thereby ensuring that the strap feeding mechanism (32, 34) will automatically engage and re-feed the strap (12). <IMAGE>

Abstract: A unitary jet impingement plate (10) is formed including a body portion (12) thereof and at least one manifold (14, 16) integrally connected with the body portion (12), each having internal passages (22) in fluidic communication with one another. At least one jet impingement orifice (18) is provided through a plate (20) of the body portion (12) of the jet impingement plate (10) through which heat transfer fluid can be directed into a fluid jet of such heat transfer fluid from the jet impingement plate and for impinging on a component or object to the thermally effected thereby. The heat transfer fluid may be heated or cooled as required depending of the specific application. Preferably, the jet impingement plate is structurally enhanced by the provision of integral posts (48) provided in a pattern within the body portion (12) of the jet impingement plate (10). More preferably, a plurality of jet impingement orifices (18) are provided in accordance with a predetermined pattern designed for a particular application. Such a unitary jet impingement plate (10) including integral posts (48) is advantageously made by using a sacrificial core (30) designed to provide the body portion (12) and manifold (14, 16) of the jet impingement plate (10), and depositing forming material about the sacrificial core. After deposition, at least one access opening is needed through which the sacrificial core can be removed by melting, dissolving or decomposing.  The at least one jet impingement orifice (18) or plurality thereof can be provided while the sacrificial core (30) is within the jet impingement plate, after the sacrificial core is removed, or during the deposition.

Abstract: A valve (10) for controlling flow of hydraulic fluid.          The valve (10) includes first and second valve members (80, 82), each having a plurality of lands and grooves.  The valve members (80, 82) are relatively movable from a neutral position to a displaced position in which surface segments (202, 226, 208, 218) of respective pairs of lands overlap to form flow gaps (232, 234) for restricting flow of fluid between respective pairs of grooves.  At least one (234) of the flow gaps is divergent by having a cross-sectional flow area which increases along a direction of fluid flow therethrough and at least one (232) of the flow gaps is convergent by having a cross-sectional flow area which decreases along a direction of fluid flow therethrough.  The flow gaps (232, 234) have minimum cross-sectional flow areas (A, B) defined by the surface segments.  The flow gaps (232, 234) are sized such that the minimum cross-sectional area (A) of the convergent flow gap (232) is larger than the minimum cross-sectional area (B) of the divergent flow gap (234) at a first rotational position, and are sized such that the minimum cross-sectional area (A) of the convergent flow gap (232) is smaller than the minimum cross-sectional area (B) of the divergent flow gap (234) at a second rotational position for suppressing valve noise.
