Patent CA-2184466-A1 (CA)
Title: Automatic zipper package winding and packaging machine
Inventor: IVANOV KONSTANTIN
IPC: B65B19/34
Filed: 1996-08-29
Abstract: The specification discloses an automated apparatus and method for packaging surgical needles having sutures attached thereto wherein a bundle of needles and sutures are placed at a semi-automated separation station and an operator feeds the needles, one at a time, into a rotating needle feed wheel. As the feed wheel advances, the suture is tensioned and directed along a pre-determined path to separate it from the remaining sutures in the bundle. The apparatus has a plurality of individually rotatable tool nests which are sequentially spaced on a rotating or indexing turntable. These tool nests sequentially receive plastic packages for receiving the needle and suture at a first station. At a second station, a needle is inserted into the package by robotic fingers which have retrieved the needle and attached suture from the rotating needle feed wheel. The rotating needle feed wheel and the rotating tool nests are synchronized to step together as each advances. At a third station, the package and needle are rotated to tension the suture and position the package and the suture for automatic winding of the suture into the package. At a fourth station, the rotatable tool nest is rapidly rotated to wind the suture into a circumferential channel in the package which surrounds the needle. The package is optically expected to ensure orientation and position of the needle, and to ensure that the suture has been wound entirely into the suture receiving channel. At the next station, a cover attaching mechanism stakes a cover into the package using self-locking tabs defined between the package and the cover. The labeled package is then inspected, and off-loaded at the final work station to a tray which receives a plurality of suture packages for sterilization and final packaging. While the operation of the device is computer-controlled, most of the mechanical elements are driven from a single camshaft through a plurality of cams and cam followers. Unique mechanisms are also described to separate a single label from a stack of labels, and to transfer the label for staking on the package. A unique mechanism is described for removing the package from the tool nest and either discarding the package, if it failed one of the inspection steps, or placing the package into a carrier for sterilization and final packaging.

Title: Process for preparing calcium cyanamide from urea
Inventor: WEBER GUENTER
IPC: C01C3/18
Filed: 1995-03-02
Abstract: In order to produce calcium cyanamide by reacting urea with an oxygen-containing calcium compound in at least two steps a) in a first step the reaction components are allowed to react under compression and/or while being revolved or by applying them to a hot surface at temperatures of 120 to 500.degree.C until a solid is formed and b) the solid reaction mixture that is formed is subsequently calcined at temperatures of 600 to 900.degree.C. In this process it is possible to obtain high yields and throughputs of calcium cyanamide without requiring a time-consuming processing of the reaction product after the first or second step.

Filed: 1996-10-08
Abstract: An automatic bundler which can be installed in a reduced space is obtained.   In the automatic bundler, a bobbin holder is provided at a front portion of a rotating shaft with respect to a vertical wall.   The bobbin holder therefore does not protrude rearward from a machine frame, and therefore the automatic bundler may be installed in a reduced space as compared to conventional cases.   In another aspect of the invention, first and second direction change members for changing the direction of string by 90° are provided at a corner and a free end of a string winding arm, respectively, and therefore, a flat string may be wound around an object W as flat as it is.          Furthermore, according to the invention, the string tying/cutting device is operated by a motor for operating the string tying/cutting device irrespectively of an arm operating motor, and therefore, the string may be wound around the object an arbitrary number of times.

Abstract: A continuous process for preparing a high protein or low fat nut spread having desirable fluidity, texture and flavor. The process comprises as a first step depositing a nut paste in a mixing tank. Next, the solid ingredients which are to be present in the final product spread are mixed into the tank containing the peanut paste and the mixture is pumped through a high shear mixer. The temperature of the mixture is then adjusted so that the temperature of the mixture exiting the homogenizer is less than about 240 DEG  F. The mixture is then pumped through a homogenizer at a pressure ranging from about 9,000 to about 14,500 psig, a colloid mill, a versator and a scraped wall heat exchanger. Nut spreads having a monomodal or bimodal particle size distribution such that at least 50% of the solids in the nut spread have a particle size of less than 18 microns and 90% of the solids in the nut spread have a particle size of less than 60 microns, and further having a Casson plastic viscosity of from about 8 to about 17 poise and a yield value of less than about 300 dynes per square centimeter are produced according to this process.
Patent CA-2191595-A1 (CA)
Title: Superatmospheric reaction
Inventor: GOZUM JOHN E
IPC: C08F26/06
Filed: 1995-07-07
Abstract: A polymerization process produces polymers that are insoluble in a reaction mixture that was homogeneous before the polymer began to form. A dispersing agent in the polymerizing system (i.e., the reaction mixture plus the dispersing agent) allows a kinetically stable dispersion of the polymer to be formed in this polymerizing system. Also, an olefin metathesis process allows for the production of polymers, the crosslinked of existing polymers, or the decrosslinking of crosslinked polymers. Both the polymerization and metathesis processes are performed under superatmospheric conditions.
