Patent CA-2169294-A1 (CA)
Title: Transmission mechanism
Inventor: WILLMOT ERIC PAUL
IPC: F16H29/18
Filed: 1994-08-05
Abstract: A transmission is disclosed which has an input power supply (53, 34, 328) and a plurality of secondary members which are driven by the input power supply. The secondary members can be in the form of pawls (344, 361) or rack and pinion arrangements (54, 56). An infinitely variable gear ratio adjustment mechanism which can adjust the gear ratio between a maximum and minimum ratio is provided and generally comprises a fixed inner eccentric (318) and a movable outer eccentric (320). The outer eccentric (320) can be moved to adjust the eccentricity of the eccentrics to thereby set the gear ratio to any ratio between the minimum and maximum. The pawls (344, 361) or racks and pinions (54, 56) arc arranged on the eccentrics (318, 320) and are driven by the input for only part of each revolution of the input other than when the gear ratio is set as 1:1. A mechanism for ensuring that the load applied to the secondary members is distributed between at least two of the secondary members at any one time is provided and comprises a lever arrangement (106), a floating ring arrangement (76) or a resilient biasing rubber ring (380, 382).

Patent CA-2171625-A1 (CA)
Title: Oxidized carotenoids, retinoids and related conjugated polyenes, and derived fractions and compounds useful as cell-differentiation inducers, cytostatic agents, and anti-tumor agents
Inventor: BURTON GRAHAM
IPC: C07C403/16
Filed: 1995-08-10
Abstract: .beta.-Carotene, lycopene and canthaxanthin, as represented by carotenoids, retinoic acid, and representative retinoids, undergo extensive oxidation to yield substances which have properties useful as non--toxic agents active against cell proliferation, tumors, and tumorigenic viruses, and useful as promoters of cell differentiation. It is evident from chemical analysis of the highly oxidized .beta.-carotene product mixture that none of the various forms of vitamin A are present or are present only in minor amounts. Furthermore, the biological activities of oxidized canthaxanthin and lycopene indicate the presence of active substances that are different from vitamin A. Although the cytostatic and differentiation promotion activities of oxidized .beta.-carotene resemble those of vitamin A itself, generally the effects are more powerful for oxidized .beta.-carotene in a wide variety of circumstances. Unlike vitamin A, the oxidized .beta.-carotene of the invention is non-toxic. The oxidized carotenoid is a mixture of compounds which can be fractionated. The fractions exhibit anticancer activity comparable to, or higher, than the activity of unfractionated oxidized carotenoid.

Title: Stable complexes of crosslinked polyvinylpyrrolidone and iodine and method of making the same
Inventor: KULKARNI ARUN B
IPC: A61K47/32
Filed: 1996-06-06
Abstract: A wound treatment material which absorbs wound fluid without overdrying the wound, provides physical cushioning for the wound, and releases an antimicrobial agent (iodine) in a controlled manner to kill harmful micro--organisms without irritating the wound area or adversely affecting would healing. The wound treatment material comprises crosslinked polyvinylpyrrolidone-iodine complex which is water insoluble, but water-absorbent and water--swellable. When the complex or a wound treatment preparation containing the complex is applied to a wound, i.e., becomes hydrated, and an equilibrium is established between the complex and the wound at the wound/complex interface. Iodine is releaed from the crosslinked polyvinylpyrrolidone-iodine complex by a diffusion controlled process which responds to the reduction in concentration of free iodine in the wound fluid in equilibrium with the complex. The greater the rate of iodine depletion in the wound, the greater the rate of iodine release from the polymer-iodine complex. It has been discovered that this diffusion controlled release mechanism can be utilized to deliver antimicrobially effective amounts of iodine to the wound while maintaining the concentration of iodine below the concentration that could cause significant wound irritation or retardation of healing. It has also been found that the moist environment at the wound/complex interface and the physical protective effect (cushioning) offered by the hydrated complex can enhance wound healing.
