Patent CA-2258687-A1 (CA)
Inventor: GAVAN JOHN CHARLES
IPC: H04N1/32
Filed: 1997-06-23
Abstract: An intelligent services network platform (ISN) of a telephone carrier network is equipped with a fax store and forward (FSFS, 10) capable of relaying fax transmission between a customer's fax machine (14) and an international destination. An autodialer (15) associated with the fax machine (14) automatically dials an 800 number designating the FSFS (10). It also automatically dials the preselected destination number and concurrently transmits an identification of the transmitting fax machine. An automatic call distributor (22) in the ISN (12) responds to the 800 number and transfers the fax transmission to an automated response unit (26) which validates the customer's call. Thereafter, the FSFS (10) is enabled to communicate directly with the sending fax machine to receive and store the transmitted fax. The FSFS (10) will subsequently relay the fax transmission, even if repeated attempts are necessary, to the international destination through a bridging switch (20) in the ISN (12) and an international gateway switch (18) connected to the network (16), external of the ISN (12). The FSFS (10) generates confirmations for the customer and billing data.

Abstract: There is provided a system for locking skis of a snowmobile to a platform. The system includes a shaft having a lower portion secured to the platform and an upper portion for supporting an adjustment nut and a handle that rotates about the upper portion. The upper portion of the shaft has threads at its outer surface. Also, a bar is situated below the adjustment nut so that it may be adjusted between a first position where the bar holds the skis against the platform, and a second position where the bar releases the skis. In particular, the adjustment nut changes its vertical position when rotated about the upper portion of the shaft and, thus, is capable of adjusting the vertical position of the bar as well.

Patent CA-2273797-A1 (CA)
Inventor: EVERHART DENNIS S
IPC: B05D1/28
Filed: 1997-12-17
Abstract: The present invention comprises methods of contact printing of patterned, self-assembling monolayers of alkanethiolates, carboxylic acids, hydroxamic acids, and phosphonic acids on metallized thermoplastic films, the compositions produced thereby, and the use of these compositions. Patterned self-assembling monolayers allow for the controlled placement of fluids thereon which contain a chemically reactive, indicator functionality. The optical sensing devices produced thereby when the film is exposed to an analyte and light, can produce optical diffraction patterns which differ depending on the reaction of the self-assembling monolayer with the analyte of interest. The light can be in the visible spectrum, and be either reflected from the film, or transmitted through it, and the analyte can be any compound reacting with the fluid on the self-assembling monolayer. The present invention also provides a flexible support for a self-assembling monolayer on gold or another suitable metal.

Title: Casement window roto-operators
Inventor: HUML JAN M
IPC: E05F11/34
Filed: 1999-07-22
Abstract: A window operator, particularly, operators for venting casement windows is provided. The base housing of the operator is of a plastic polymer, which is a non-corrosive and non-thermal conducting material. The top and bottom base components are then sonic welded with a heat-treated steel worm gear welded inside of the plastic base of the window operator creating a one-piece assembly. The worm gear and pinion gear with attached operator arm are placed within the base body before fusion welding the top body. The use of the plastic polymer for the base housing eliminates the possibility of corrosion of the base material. Also, the polymer does not require finishing or painting to protect it from corrosion.
