Patent CA-2032510-C (CA)
Inventor: NOGUCHI NORIYASU
IPC: A61F2/958
Filed: 1990-05-09
Granted: 1996-11-05
Abstract: The present invention relates to a catheter with a balloon characterized by a feature that the balloon is reinforced with a composite yarn consisting of an elastic yarn and a non-elastic yarn with a larger free length than that of said elastic yarn.    As the catheter with a balloon has a balloon with large stretchability, when the catheter is inserted into a blood vessel or taken out on a surginal operation, it is possible not only to make surely the diameter small without producing any wrinkle but to stretch surely to the same size and the same shape at any time.  Therefore, not only reliability of the surginal operation is improved but also a cut wound for the surginal operation could be smaller.  There exist such advantages that treatment and management after the surginal operation are simple and the time required for recovery is extremely short and smaller daily burdens of a patient and an attendant are needed.

Abstract: Disclosed is a rattrap usable for fighting rats where these occur at large numbers, e.g. in sewer systems. The trap is mounted in an elevated position and has a hanging climbing rope (12) leading up to a delivery area (20) for an alluLrement. When a visiting rat gets its nose up to this area, this approach is automatically detected, and a beater jaw (8) is actuated against the neck portion of the animal. The animal is removed from the area simply by falling down therefrom, whereafter the trap is ready for the next operation. The supplies of allurement and the capacity of the associated energy sources (battery, CO2-bottle) may be sufficient for unattended operation through such a long time, e.g. some months, that the trap may in the meantime execute hundreds of rats.

Granted: 1998-02-10
Abstract: A method of preparing a catalyst particularly useful in the reaction of ethylene, oxygen and acetic acid in the vapor phase to form vinyl acetate comprises impregnating a porous support with water soluble salts of palladium and gold, fixing the palladium and gold on the support as water insoluble compounds by immersing the impregnated support in a reactive solution and tumbling the impregnated support in the reactive solution for at least 1/2 hour to begin precipitation of the insoluble compounds and completing precipitation of the insoluble compounds on the support and reducing the insoluble compounds to free palladium and gold. The catalysts prepared in this manner have been shown to provide improvement with respect to reduced selectivity to CO2, during the vinyl acetate forming reaction.

Abstract: For delivering parts successively received in  shipment units  by  parts  deliverer  to  part  use  positions,   the delivering operation time required for each parts  deliverer is  uniformalized.  A uniformalizing plan is  produced,  and the delivering operation is continued according to the plan.    The  delivering  operation  time  is  calculated  for   each shipment  unit (first step).  The  assignment  of  shipment units to parts deliverers is shifted such as to uniformalize the  delivering  operation  time for  each  parts  deliverer (third  step).   The shifting operation is  continued  until uniformalizing  is  obtained.  As  a  result,  uniformalized assignment can be realized.
