Title: Ophthalmic refractor having retrofittable readout illumination
Inventor: HOOVER DOUGLAS H
IPC: A61B3/028
Filed: 2002-10-03
Abstract: A subjective ophthalmic refractor is improved for operator visibility in a darkened examination room by forming a cylinder axis scale of the refractor as a light- transmitting component having opaque scale gradations and installing a polar array of illumination sources to project light through the cylinder axis scale, which preferably includes a translucent material for diffuse illumination. In an alternative embodiment, the cylinder axis scale includes a photoluminescent material to which the scale gradations are applied. The refractor is further improved by installing respective illumination sources near a cylinder power readout and a sphere power readout of the refractor. The disclosure additionally relates to a method for retrofitting an ophthalmic refractor to illuminate the cylinder axis scale, cylinder power readout, and sphere power readout.

Patent CA-2409695-A1 (CA)
Inventor: FUQUEN ORLANDO
IPC: B65D81/32
Filed: 2001-05-09
Abstract: The present dual chamber sachet (30) overcomes the problem of non-uniform dispensing when the sidewalls of the sachet are depressed. Through the use of a relatively thin intermediate divider wall (48), rounded corner edges (42) at the lower end of each chamber (32, 35) of the sachet, tapered side edges (44, 46) up to the exit channel (36) of each chamber of the sachet, and a relatively wide dispensing opening uniform dispensing can be achieved. This structure prevents the downward flow of substances in each chamber during dispensing. The substances are directed upwardly by the rounded lower corners of the sachet, the tapered upper walls and the wide dispensing opening. This relatively wide dispensing opening minimizes the back pressure caused by the substances flowing to a dispensing exit of a width less than that of the product chambers.

Patent CA-2411531-A1 (CA)
Inventor: GRIFFIN CHRISTOPHER
IPC: G05G1/08
Filed: 2002-11-12
Abstract: A handle is provided for an operator that provides overtorque protection for the operator. The handle includes a hand grip connected to a connecting shaft, which is mateably received in the operator. The connecting shaft includes at least one weakened section which breaks or fractures in the event an excessive amount of torque or force is applied to the handle. As a result, the handle breaks when the user applies an excessive amount of torque to the handle in an effort to open or close the structure connected to the operator. The broken handle may be easily replaced by removing the broken section of the connecting shaft from the operator and replacing the handle by inserting the new handle with a new connecting shaft into the operator. The gear mechanism disposed within the escutcheon of the operator is protected from the excessive amount of torque or farce and, accordingly, the handle is intended to break before the operator which avoids the need for replacing the entire operator.

Patent CA-2427157-A1 (CA)
Title: Marine truss dock system
Inventor: DOIG DANIEL J
IPC: E02B3/06
Filed: 2003-04-29
Abstract: The nature of this unique design is that when the top and bottom female toggle on the middle support are simultaneously put on the male toggle of the side truss. a collision fit is obtained. This is due to the angle which is above the female toggle on the top and under the female toggle on the bottom. There is a bolt which gets threaded through the female toggle, then continuing through the diagonal cross brace then threaded through the remaining female part of the toggle. The bolt then continues through into the male toggle in a pinned configuration due to a hole being drilled into the male toggle. Therefore, this allows the truss dock side sections to twist. The diagonal cross brace at each corner, as well as the mechanical connection at each mid support, limit the amount of twist. As example, if a wave were to lift one comer of the dock approximately 6", the dock can flex or twist then revert to the original static position without suffering the structural damage of a rigid welded frame if it were flexed.

Title: An information management system
Inventor: MALCOLM PETER BRYAN
IPC: G06F12/14
Filed: 2001-11-08
Abstract: An information management system is described comprising one or more workstations running applications which allow a user of the workstation to connect to a network, such as the Internet. Each application has an analyser, which monitors transmission data that the application is about to transmit to the network or has just received from the network, and which determines an appropriate action to take regarding that data. The analyser may consult policy data containing a supervisior-defined policy to govern the workstations in order to determine what action to take. Such actions may be extracting data from the transmission data, such as passwords and usernames, digital certificates or eCommerce transaction details for storage and record keeping;  ensuring that the transmission data is transmitted at an encryption strength appropriate to the contents of the transmission data; determining whether a check needs to be made as to whether a digital certificate received in transmission is valid; determining whether a transaction about to be made by a user of one of the workstations needs third party approval before it is made;  and controlling the transmission of messages, such as e-mails according to a policy.
