Patent CA-2113672-C (CA)
Inventor: HUBA FRANCIS
IPC: B01J38/00
Filed: 1994-01-18
Granted: 1997-05-13
Abstract: A novel process and chemicals are disclosed for the rejuvenation of oxidation catalysts used to reduce the production of pollutants in the exhaust gas emanating from an internal combustion engine, particularly catalysts used in theconverters of automobiles and other combustion engine powered vehicles. The rejuvenation may be done in place, within minutes, without removing the holding containers or converters or the catalyst from them. The rejuvenation is effectedby treating the used catalyst with an aqueous solution of a peroxide which is decomposable at the temperature of treatment. The concentration of solution, theproportion of solution per unit volume of catalyst and the time of treatment areimportant factors in the effectiveness in regenerating or rejuvenating the catalyst.

Abstract: A circularly polarized microcell antenna 10 that requires only a single feed-line to radiate circularly polarized electromagnetic energy therefrom. The antenna 10 comprises a reflector box 14 having a bottom 15 and side walls 17 to which an electrical connector 20 is mounted. The center conductor 24 of the connector 20 is electrically connected to a conductor bar 22 upon which a first dipole assembly is mounted at a designated one-quarter wavelength location. The shell of the connector 20 is electrically connected to the reflector box 14 upon which a second dipole assembly is mounted at a designated one-quarter wavelength location. Each dipole assembly comprises a primary dipole arm 52 and a secondary dipole arm 68 which are electrically connected by a phasing loop that introduces a 90° phase shift between the primary dipole arm 52 and the secondary dipole arm 68. Thus, a single feed-line is capable of feeding both the primary and secondary dipoles so as to allow circularly polarized electromagnetic energy to radiate therefrom.

Title: Retinoic acid-containing compositions
Inventor: QUIGLEY JOHN W JR
IPC: A61K47/34
Filed: 1993-04-20
Granted: 1998-12-15
Abstract: Novel retinoic acid-containing topical compositions in the form of creams, lotions, gels, and the like, are disclosed. These compositions contain a urethane compound having a molecular weight of up to about 60,000, prepared by reacting approximately two moles of a hydroxy-terminated linear alkylene or polyalkylene glycol with approximately one mole of a monomeric organic diisocyanate. The presence of the urethane compound leads to decreased percutaneous transmission of the retinoic acid, resulting in reduced skin irritation but undiminishes therapeutic effectiveness of the retinoic acid when compared to retinoic acid-containing topical formulations otherwise identical except for the absence of a urethane compound. The compositions of this invention can be used to treat acne vulgaris and ameliorate photoaging of the skin, to retard and reverse the effects of senile keratosis, and to treat a variety of other skin conditions, such as hyperpigmentation and psoriasis, hitherto considered unsuitable for treatment with retinoic acid.

There the different narrowband components are detected, for example using a demultiplexer (7) and the resulting signals processed by control electronics (8).  The head-end station also includes an optical circuit arranged to split a signal from a broadband source (9) into different narrowband components. Electro-optic modulators (FOM) modulate the different narrowband components and the resulting narrowband signals are output onto the fibre network (2) and transmitted to the actuators. The electro-optic modulators (FOM) are operated by the control electronics (8).

Title: Bone graft delivery system and method
Inventor: SMITH MARGARET E
IPC: A61B17/88
Filed: 1995-10-10
Granted: 1999-08-24
Abstract: A surgical technique for the delivery of bone graft  to  a  medullary  canal  and  implantation  of  a prosthetic device includes placing bone graft into an elongate hollow tube and arranging a plunger having an elongate rod portion into the hollow tube.   The hollow tube, bone graft and plunger assembly are inserted into the medullary canal which has been prepared for the assembly by reaming the medullary canal with a reamer corresponding in size to the hollow tube.   The hollow tube is withdrawn from the medullary canal while the plunger  is pushed  into the canal,  resulting  in bone graft exiting the hollow tube and being packed by the plunger.  A trial prosthesis is used to shape the bone graft within the canal for the prosthesis.  Space for a cement  mantle  can  be left  through  the  use  of  an appropriately sized trial prosthesis.
