Patent CA-2270222-A1 (CA)
Inventor: PEDERSEN SOREN CHRISTIAN
IPC: G01N21/359
Filed: 1997-10-31
Abstract: The present invention relates to an on-line method and a flow system as well as a cuvette for carrying out IR spectrometry for analysis of liquid food products, possibly containing dissolved gases, in a process line in a liquid food product processing plant, especially a dairy processing milk and milk products. A liquid sample is extracted from the process line to a measuring branch, the sample is thermostated and passed to a measurement cuvette. The IR-absorbance spectrum is measured, e.g, in the MID-IR or NIR-range. In order to obtain an on-line monitoring of the process line the liquid food sample is extracted directly from the process line into the measurement branch, in which the pressure is maintained at least as high as in the adjacent process line. The high pressure ensures that dissolved air will stay dissolved in the liquid food. Before each new sample the measurement branch and cuvette are flushed by high flow rates with a part of the new sample to clean the cuvette. The measurement cuvette has strong windows, preferably diamond windows to stand a high pressure and high flow rates. The on-line system is arranged to carry out e.g. 120 measurements per hour.

Abstract: A golf putter comprises a shaft having a grip at one end and a head fixed to the opposite end. The head has a main body section that extends transversely of the shaft. The main body section has a generally cylindrical configuration with a diameter substantially less than that of a standard golf ball. The main body section is encapsulated by a layer of resilient, fraction-enhancing material that extends across the striking face of the club head to grip the ball on impact and provide a cushioned, controlled feel when striking the ball. The putter head is formed with a counter weight stabilizer leg that extends forwardly or rearwardly of the body at an angle with respect to the shaft of the club. The leg acts to stabilize the body of club head during the back stroke and on the return stroke to assist in keeping the face of the club head square with the ball and target.

Title: Method and apparatus for the thermal bonding of a base part of a packaging with a cover film, and a method and apparatus for packaging contact lenses
Inventor: HEINZELMANN KURT
IPC: B65B7/28
Filed: 1998-01-23
Abstract: In a method for the thermal bonding of a base part (3) of a packaging with a cover film (F), especially for the welding or sealing of a base part of a packaging for contact lenses with a cover film, the contact surface of the base part (3) facing the cover film (F) and the corresponding contact surface of the cover film (F) facing the base part are mechanically pressed against one another along a join. While the mechanical pressure is being generated along the join, heat is simultaneously caused to act on the join, so that the contact surfaces of base part (3) and cover film (F) are thermally bonded to one another along the join. For the purpose of generating the mechanical pressure and causing heat to act on the join there is used a contact plate (70) of low heat capacity which, during the thermal bonding, is pressed against the surface of the cover film (F) remote from the contact surface. The temperature of the contact plate is measured in the immediate vicinity of the cover film, and in the event of the measured temperature deviating from a predetermined tolerance range around a desired temperature, the temperature of the contact plate (70) is within a very short time adjusted so that it again lies within the predetermined tolerance range around the desired temperature.

Title: An interactive framework for understanding user's perception of multimedia data
Inventor: RAVI TUMKUR V RAO
IPC: G06F17/30
Filed: 2000-05-01
Abstract: A methodology of highly interactive intra-object relevance feedback is used to retrieve images from a database. The query is adjusted using the information fed-back by the user about the relevance of previously extracted part(s) from the object itself, such that the adjusted query is a better approximation to the user's perception. Since a single query image is utilized in the system according to the invention, high-performance learning techniques can be employed for this intra-object learning of user's perception. The refined query is subsequently used for intra-object relevance feedback where images are retrieved from the database based on parameters learnt by intra-image feedback mechanism, and the user provides feedback by ranking the retrieved objects in order of their relevance to him or her. In the system according to the invention, intra-object learning of user's perception is expedited by utilizing the learnt parameters in the intra-object relevance feedback.  Furthermore, the methodology of the invention allows for building refined queries based on part(s) of the query object rather than the entire object itself, thereby reducing the number of irrelevant objects, retrieved from the database.
