Title: Locking system for a double hung window
Inventor: STORMO GUY C
IPC: E05C17/64
Filed: 1994-08-12
Abstract: An apparatus for selectively securing a window sash to a win-dow frame, including a longitudinally extending jamb liner secured to the frame adjacent one side of the sash, and a movable cam between the frame and the liner for selectively adjusting the spacing therebetween. Frictional locking surfaces are provided between the liner and the sash whereby the cam in a locking configuration biases the liner away from the frame and thereby against the sash to frictionally lock the sash against movement relative to the liner.

Title: Protecting programs and data with card reader
Inventor: MOONEY DAVID M
IPC: G07C9/00
Filed: 1993-06-04
Abstract: A secure computer controlling access to internal devices via an integrated card reader. A microprocessor-controlled card reader interface logically connected to the CPU of the computer reads and writes information from and to a card placed in the card reader and performs additional functions in response to commands received from the CPU. The boot ROM of the computer is programmed to start execution from a program logic device which runs a verification program to verify the authenticity of a user. Upon a valid user card being placed in the card reader, one or more questions are read from the card and displayed to the user. The user's responses are saved and compared to the correct answers stored on the card, and if the responses match the correct answers, a power control circuit is used by the CPU to turn on power to computer peripherals the user has been authorized to use.

Inventor: STOWE GENE B
IPC: C25B9/17
Filed: 1993-03-10
Abstract: An electrolysis cell (33) is provided for use in connection with a combustion engine (10), for generating hydrogen and oxygen gases which are added to the fuel delivery system as a supplement to the gasoline or other hydrocarbons burned therein. The hazard of explosion of the mixture of generated gases is eliminated by withdrawing the gases through a connection with the vacuum line of the positive crankcase ventilation (PVC) system (45) of the engine and by utilizing a slip-fitted top cap for the electrolyses cell, which cooperates with the PVC vacuum line to prevent explosive containment of generated gases in case of accident. Use of the generated gases as a fuel supplement enables substantial increases in fuel efficiency, while at the same time reducing the emission of pollutants.

An outwardly and downwardly inclined roof-shaped strip (8) extends around the periphery of the container (3), is rigidly connected to the latter, is again used as a reinforcement, and prevents bulk material passing into the space between the container (3) and the metal side plate (2). A plurality of roof-shaped webs (9) extend in the lower region of the frame (1), transversely thereto, and are rigidly connected to the metal side plates. The base of the container likewise contains an appropriate plurality of roof-shaped webs (10) alternating with the webs (9) of the frame (1). The webs (9) of the frame close the apertures between the webs (10) of the container (3) when the container is lowered into the frame. If the container (3) is raised on two pairs of vertical plates (12), the bulk material in the container (3) can run out through said apertures. The frame (1) comprises four load take-up devices (13) at which the container is raised and by means of which it can be locked to another container or to a transport device.

Patent CA-2160822-A1 (CA)
Inventor: ALTOM MARK W
IPC: G06F3/033
Filed: 1995-10-18
Abstract: A graphical user interface, i.e., multimedia communications application program, for setting up and handling a multimedia call is disclosed that employsrealistic metaphors of real life face-to-face meetings in setting up and handling a multimedia call to establish a virtual meeting which is automatically reconfigured in response to user action. This is realized by taking advantage of prospective virtual meeting participants' already existing knowledge of how real life face-to-face meetings operate. To this end, the multimedia communications application programenables the virtual meeting participants through direct manipulation of the realistic graphical metaphors to establish a realistic virtual meeting room which is displayed on the screen of their workstation monitor. The virtual meeting room includes a table and chairs arranged in a realistic manner in the virtual meeting room. The virtual meeting room and table are automatically configured in response to user action in such a manner as to minimize the screen area displaying the virtual meeting room and, thereby, maximizing the screen area available for multimedia collaboration by the meeting participants. An empty chair is displayed at the table which indicates that at least one more participant can be added to the virtual meeting. Once a predetermined maximum number of participants have been included in the virtual meeting, the empty chair is no longer displayed.
