Patent CA-2054603-A1 (CA)
Title: Portable arthroscope with periscope optics
Inventor: LAFFERTY MICHAEL
IPC: A61B1/055
Filed: 1991-10-31
Abstract: ABSTRACT    A hand-held portable arthroscope has a camera assembly and a disposable scope assembly rotatably attached to the distal end of the camera assembly.  A probe which includes a fiber  optic  image guide  and  a  plurality  of  optical illuminating  fibers  is  rotatably  mounted  on  the  scope assembly,  and is insertable into a body for  imaging the internal structure of the body.   The illuminating fibers extend through the scope assembly and are connected in light communication with a quartz halogen lamp for illuminating the internal body structure being imaged.  To gather light from the illuminated internal structure of a body into which the probe has been inserted, a GRIN rod is attached to the distal end of the image guide.   The image guide is bent near its distal end to offset the axis of the GRIN rod from the axis of the camera assembly, to enhance the field of view of the arthroscope when the scope assembly, which supports the image guide with GRIN rod, is rotated.    Focussing optics are mounted in the camera assembly in light communication with the image guide.   These focussing optics are axially movable within the camera assembly for focussing the image from the image guide.  Light which passes through the focussing optics enters a camera head which is also mounted in the camera assembly.  The camera head is in turn electrically connected to a video display device for producing an image of the internal structure of the body. PATENT:  10957.4

Title: Lag and bump putting game
Inventor: POSTULA VICTOR A
IPC: A63B67/02
Filed: 1992-02-25
Abstract: ABSTRACT OF THE DISCLOSURE     A  golf putting game is played with regular golf  balls  and clubs  on  an elongated rectangular playing  area.   The  players stand  at one end of the area and putt toward the far  end.  When putting  the players must stand behind one of a series of  trans-verse  lines, which are assigned by handicap.  At the end of  the playing area distal the putting lines is a shallow ramp.  Several holes or depressions in the surface of the ramp, called "bunkers" in the game, act as ball traps. The playing area is  conveniently made  up in the form of a roll-up mat.  The game itself  has  two phases.  In phase one, the players attempt to putt balls into one of  the bunkers to accumulate points   Phase two of the game  has three  embodiments, in all of which the players attempt  to  land their  putts in one of the last three rectangles defined  by  the transverse  lines to score.  Bunker balls do not count  in  phase two.  Score points are counted only at the end of a round of play in  two of the embodiments, which encourages strategy and  "bump-ing"  of opponents' balls out of the score rectangles.  The  win-ning  team is the first to reach a certain total score in two  of the  phase two embodiments, and is the team with the most  points after eight rounds in the other.

Title: Method and device for controlling the amounts dosed and dispensed by a dosing/dispensing apparatus
Inventor: TORTEROTOT ROLAND
IPC: G01F11/02
Filed: 1991-07-25
Abstract: ABSTRACT      The invention concerns a process for adjusting the quantities of product dosed and dispensed by a doser-dispenser (20), the food or pharmaceutical product preferably being in a liquid and/or pasty state.     The weight of at least every nth of the recipients (101) filled by the same doser-dispenser (20) with a dosed quantity of the product (102) is measured, the whole number n being included between 1 and 1000, each weight value measured is compared with a predeter-mined standard value and at least one of the end-of-stroke positions of the doser piston of said doser dispenser is adjusted step by step and during the operation of the doser-dispenser (20), in the sense of increasing or decreasing the stroke of the  doser piston as soon as the difference between the real weight measured and the predetermined standard weight exceeds a limiting value, and such adjustment is continued until said difference disappears.

Patent CA-2070383-A1 (CA)
Inventor: TASAKI TAKAHARU
IPC: B05B7/00
Filed: 1991-10-01
Abstract: Herein disclosed is a foaming nozzle to be mounted in the front of a spray nozzle of a sprayer so that a liquid detergent may be sprayed in a foamed state onto a window glass or the like to clean it. The foaming nozzle has its mouth so shaped that the mixed cluster of the mist and foam from the foaming nozzle may be sprayed in a band, elliptical, rectangular or triangular shape and at a wide angle. At the same time, the positional relation between a spray port and the foaming nozzle is so determined that the mist spin-sprayed at a high swirling speed may be partially mixed with the foam, which is formed by the impingement of the mist upon the inner face of the mouth of the foaming nozzle, and that the mixture may be sprayed at a wide angle. The foaming nozzle is composed of first and second foaming nozzles, of which the first one is mounted in the spray nozzle, as described above, whereas the second one is formed into the shape of a circular cylinder and removably hinged to the first one so that the mist-foam mixed cluster may be sprayed in the sectional shape of a band from the first foaming nozzle with the second foaming nozzle being removed and so that foam may be sprayed in the sectional shape of a circle with the second foaming nozzle being unremoved. In short, the user can selectively spray either the mist-foam mixed cluster having the band section or the foam cluster having the circular section freely, if necessary.

Title: System comprising a container having a slit valve as a venting valve and a liquid contained in said container
Inventor: BILANI NADI
IPC: B65D47/20
Filed: 1993-02-12
Abstract: In a system comprising a container and a liquid contained therein that builds up a gas or vapour pressure, a sealing valve having a concave shaped portion and a slit extending through said portion, allows venting of the vapour from the container to the ambient at a predetermined vapour threshold pressure.  The vapour threshold pressure at which the slit opens for venting can be adjusted by valve restraining means which are preferably formed by a protrusion at the inside of a cap covering the sealing valve.  The vapour threshold pressure at which venting takes place, can to a large extent be adjusted without affecting the dispensing characteristics of the valve.

Title: Method for the production of compacted graphite cast iron
Inventor: BAECKERUD STIG L
IPC: G01N33/20
Filed: 1991-10-11
Abstract: A method relating to the production of cast iron castings with compacted graphite crystals. The method comprises controlling and correcting the composition of the cast iron melt and securing the necessary amount of structure modifying agent. A sample of the melt is taken with a sample vessel provided with two thermocouples, one positioned so as to be in the centre of the sample and the other positioned so as to be in the vicinity of the vessel wall.  The vessel wall contains or is coated with a layer of a substance which will lower the concentration of dissolved elementary magnesium in the melt in the vicinity of the vessel wall by at least 0.003 %. The temperature/time values obtained through two temperature responsive means are recorded. The occurrence of a plateau temperature will provide information as to the precipitation of flaky graphite in the vicinity of the vessel wall, therewith enabling corrections to be made to the concentration of the modifying agent and to ensure the formation of compacted graphite crystals during the whole of the pouring time required in the foundry processconcerned.

Title: Process for the production of a low-sugar, alcohol-free beverage
Inventor: GRESCH WALTER
IPC: A23L2/74
Filed: 1993-01-19
Abstract: A process for the production of a low-sugar, alcohol-free beverage comprises a desugarization process, which is upstream to a preliminary separation. Through the preliminary separation, the raw juice is divided into two streams (A,B), of which the first stream, relative to the raw juice, has a lower acid/sugar ratio and a higher sugar content and the second stream has an elevated acid/sugar ratio and a lower sugar content. The first stream is directly fed to the desugarization process, while the second stream is fed to the low-sugar juice after the desugarization process. The second stream contains a high portion of acid and other, low-molecular components and thus when mixed with the first stream, increases the total content and the quality of the end product.
