Patent CA-2112329-A1 (CA)
Inventor: UCHIDA HIROMICHI
IPC: B65H35/07
Filed: 1993-12-23
Abstract: An automatic adhesive transfer device used with an adhesive tape is disclosed, which is for use to bond desired portions of paper or the like in offices, home, schools, etc.  In the device, an adhesive tape roll, which is formed by winding an adhesive tape comprising a double-side release paper with an adhesive coating thereon with the adhesive coated surface on the outer side, is loaded in a casing.  In the use of the device, the adhesive tape roll can be rotated only in the direction of adhesive transfer and at a rotational speed suitable therefor.  The device is thus not damaged by applying force to it in the opposite direction (i.e., rotation-blocked direction).  In addition, it is possible to transfer the adhesive to a desired location accurately at all times.

Title: Pyropheophorbides and their use in photodynamic therapy
Inventor: PANDEY RAVINDRA K
IPC: C07D519/00
Filed: 1993-01-07
Abstract: Pyropheophorbide compounds are injected into a host and accumulate in tumor tissue to a higher degree than surrounding normal tissues. When the pyropheophorbide compounds are exposed to a particular wavelength of light the compounds become cytotoxic and destroy the tumor or diseased tissue without causing irreversible normal tissue damage. The pyropheophorbide compounds have shown improved results as compared to drugs currently used in photodynamic therapy. Further, they absorb light further in the red, optimizing tissue penetration and are retained in the skin for short time periods relative to other drugs used in photodynamic therapy.

Title: Apparatus for intermittent transfer of fluid
Inventor: RHOADES GEORGE D
IPC: F04D7/02
Filed: 1994-08-04
Abstract: APPARATUS FOR INTERMITTENT TRANSFER OF FLUID          ABSTRACT OF THE DISCLOSURE Fluid transfer apparatus comprising a fluid reservoir and a pump connected to the reservoir by a supply line, wherein the apparatus is configured so that vapor generated in the pump during periods of inopera-tion may escape from the pump cavity through the pump inlet, rather than being trapped in the pump cavity, and liquid may flow into the pump cavity from the supply line through the pump inlet to replace escaping vapor, thereby providing reliable pump start-up during inter-mittent operation.  The apparatus may be employed to pump LNG for fueling of vehicles.  Where LNG or another cryogenic fluid is being pumped, the pump is preferably driven by a motor located above the pump and connected thereto by an elongated shaft.  Shaft seals may be provided to prevent the fluid being pumped from contacting the motor or the bearings supporting the motor shaft.  A vapor trap may be provided beneath the shaft seals to prevent contact between liquid being pumped and the shaft seals.
