Patent CA-2217367-A1 (CA)
Inventor: GRONWALD JOHN W
IPC: C12N15/29
Filed: 1996-04-04
Abstract: The present invention provides the complete cDNA sequence of maize acetyl CoA  carboxylase and methods for conferring herbicide tolerance and/or altering the oil content of plants by introducing and expressing a plant acetyl CoA  carboxylase gene in plant cells. The method of imparting herbicide tolerance to a plant includes the steps of introducing an expression cassette encoding a plant acetyl CoA carboxylase or an antisense DNA sequence complementary to the sequence for a plant acetyl CoA carboxylase gene operably linked to a promoter functional in plant cells, into the cells of a plant tissue and expressing the plant acetyl CoA carboxylase gene in an amount effective to render the acetyl CoA carboxylase and/or plant cell tolerant to the herbicides. The method of altering the oil content in a plant includes the steps of introducing an expression cassette into plant cells and expressing the acetyl CoA carboxylase gene in an amount effective to alter the oil content of the cells. The expression cassette can also be introduced into other host cells to increase yield of a plant acetyl CoA carboxylase so that crystallized enzyme can be used to screen and identify other herbicides that bind to and inhibit the enzyme.

Abstract: An apparatus for measuring deposits in pipelines is disclosed. The apparatus consists of a fluid immersible body being sized and shaped to be insertable into a pipeline to at least partially block a flow of fluid past said body in said pipeline. Most preferably, the body is made from a compressible foam portion surrounding a fluid tight electronics chamber. Attached to the compressible body are sensors to measure a thickness of any deposits on the inside of the pipeline. The sensors are connected to data storage means to record the measurements. In a preferred embodiment, the thickness is detected by proximity sensors which sense the proximity of the metal pipe wall. The device is most preferably used for measuring wax deposit thickness. In another embodiment of the invention, there is provided a method for measuring wax deposition rates in pipelines comprising passing the apparatus for measuring deposit thickness through the pipeline on a first occasion, passing the same apparatus through the pipeline on a second occasion, and comparing the measured thicknesses to calculate a rate of change of deposit thickness over time. An another embodiment of the invention, there is provided a method of measuring deposits in pipelines comprising placing a sensing device in the pipeline, passing the sensing device through the pipeline, measuring the deposits in the pipeline and recording the measurements of the deposits in an electronic format.

Title: Blowdown and venting jet noise suppressor
Inventor: JUNGOWSKI WIKTOR
IPC: F15D1/08
Filed: 1998-03-24
Abstract: The present invention relates to a noise suppressor capable of reducing the noise of a fluid vented at high pressure and high mass flow rate from an industrial source, to the environmentally acceptable noise level. The invention combines two principles of dissipation of fluid stream energy: first, stream pressure is reduced by passing the stream through a swirler to split the stream into a number of smaller tangential streams which dissipate their energy along the spiral flow path due to friction; and next, the resulting streams pass through a tightly packed granular bed to reduce further the pressure and velocity of the exiting jet to atmospheric pressure and subsonic velocity, respectively. Such jet will generate much lower noise level, as compared to high pressure jet with cellular structure and supersonic velocity.

Title: Method for adjusting the inking for a pressrun in a rotary printing machine
Inventor: ENDISCH MARTIN
IPC: B41F33/00
Filed: 1998-05-12
Abstract: The  invention provides  a method for  arranging  the inking for a pressrun in a rotary printing machine.   The rotary printing machine has  an  inking mechanism  and  a dampening mechanism.   The ink quantity transmitted by an ink ductor is adjusted by zone via ink zone ductor blades. When the dampening mechanism is switched off, the run-up curve of the inking mechanism is initially adjusted at an average surface coverage over the entire surface, so that a  constant  ink  density  corresponding  to  the  average surface coverage results on the printing stock for all printing  speeds.    The  run-up  curve  of  the  dampening mechanism is adjusted subsequently, wherein the ink zone ductor blades are in different positions which correspond to various surface coverage values of a printing subject customarily  printed  by  the  printing  machine.     The adjustment is effected in such a way that the ink zones with  average  surface  coverage  deliver  a  constant  ink density to the printing stock for all printing speeds. The surface coverage in ink zones not having the average surface coverage is measured at different printing speeds. A  measurement  for  the  readjustment  of  the  ink  zone measuring devices is obtained from the deviation of the measured  surface  coverage  from  the  reference  surface coverage.    For  each  of  the  surface  coverage  values, characteristics lines are obtained for the readjustment of the ink zone measuring devices which is dependent on the printing speed.

Abstract: An outlet gate assembly for a hopper type railway car includes a frame adapted to be mounted on an outlet opening in the rail car and a gate in the frame. A conventional rack and pinion opening and closing drive moves the gate between open and closed positions on the frame. An inertial latch mechanism latches the gate in the fully closed position. Actuation of the opening and closing drive displaces the latch to automatically unlatch the gate. Upon impact, an inertial mass generates a latching force holding the latch closed and preventing opening of the gate.
