Patent CA-2278969-A1 (CA)
Title: Safe transmission of broadband data messages
Inventor: WITSCHORIK CHARLES ARTHUR
IPC: H04M11/00
Filed: 1999-07-28
Abstract: An arrangement for providing secure transmission of information. The bulk of the information is transmitted over non-secure channels such as broadcast media which terminate on a plurality of receiving stations. However, a residue of data is transmitted over a protected channel, such as a point-to-point channel, established for example, by a telephone connection. Interception of a complete message, when only the bulk of the message is available, becomes very difficult. It becomes even more difficult if scrambling arrangements are used to select the particular bits of the data message that are transmitted over the secure channel. It becomes still more difficult, if the data transmitted over the secure channel, itself, alters the scrambling algorithm.

Patent CA-2280982-A1 (CA)
Title: Computer anti-theft system
Inventor: STEPHENS BRUCE RANDALL
IPC: G06F21/00
Filed: 1999-08-27
Abstract: A computer anti-theft system that includes a remote transmitter unit carried by the use, a dongle that physically attaches and selectively locks onto the parallel port on an existing computer, and a software program that is loaded into the computer's memory. When the system is activated, the remote transmitter unit transmits pulse code signal which is received by a receiver component located inside the dongle.      When the pulse code signal is received, the dongle remains in its hibernating state. When the dongle is in the hibernating state, a return pulse code signal is transmitted to the remote transmitter unit and the loop continues. If no pulse code signal or return pulse code signal is received, then the dongle and remote transmitting unit, respectively, become fully activated thus creating an alarm status. In one embodiment, the software program is used to control a solenoid inside the dongle to lock the dongle onto the parallel port. The dongle end remote transmitter are electrically self-contained thereby enabling the computer to be turned off.

Patent CA-2281419-A1 (CA)
Inventor: PROST LUCIE
IPC: A23B4/24
Filed: 1999-09-02
Abstract: The apparatus to process foodstuffs with a water enriched with ozone, by washing, has at least two reserves of an initial solution (41), a supply (22) of a gas mixture containing ozone, a station (23) where ozone is added to a fresh water supply and an injection system (25,L1-L3) to feed the water with ozone into each reserve. The injection system has at least two control units (27) to determine the vols. fed into the reserves. The dissolved ozone content in the water flow is equal to or greater than the highest ozone content in the reserves. A monitor system (46,47) registers the ozone content at each reserve to be passed to a data processing unit (26) for comparison of the ozone level at each reserve. Deviations are corrected by the feed controls (27), to maintain the required ozone content level, through command signals (28) from the data processing station (26). A buffer store (25) can be supplied with water containing ozone, with outlet lines (L1-L3) to the reserves (41), each with a flow control (27). At least one of the reserves has a secondary feed line (21b) of additional water as an independent feed, or into the ozone water supply downstream of the control point. The ozone water at the reserve is recirculated in its own circuit, including another reserve, or in a circuit containing the primary supply (21) and the ozone treatment station (23). A filter is in the recirculation for the water from the reserve and also for water with ozone, before it reaches the main supply point in the circuit. The system to apply ozone to the water can have a buffer store, for the ozone action, fed from the main supply and with outlet lines to the reserves through control points. The ozone treatment buffer has an inner porous diffuser, to deliver the processing gas, and a closed loop where ozone can be dissolved in the water flow. At least one of the reserves is fitted with an injection system, to deliver ozone into the stored water. An Independent claim is included for a water processing operation, where ozone is introduced into it. The water with ozone is held in reserves, and a water flow to the reserves is treated with ozone to be dissolved in it. Preferred Features: The water with ozone is passed to a buffer store, to be distributed to the reserves, with controlled feed flows. The water level is monitored at each reserve to determine the main feed of water containing ozone and a secondary feed.

Title: Process and device for monitoring the degree of wear of a compression worm conveying plasticized material
Inventor: BACHER HELMUT
IPC: B29C48/74
Filed: 1998-04-20
Abstract: This invention concerns a process for monitoring the degree of wear of a compression worm (8) which conveys a plasticized material, in particular, plastic, against an element that exerts a resistance and is located in a worm housing (4). To this effect, the pressure of the material conveyed is measured at two points disposed at intervals along the direction of travel.     These two points are situated at both sides of a resistance body (12) towards which the compression worm (8) conveys. The difference between the two pressures measured is used to display the degree of wear of the worm (5) and its housing. A device for that purpose has an opening (18) which penetrates the wall (20) of the housing (4) of the worm (5) in the region of its thread or in a region immediately adjacent thereto. An additional opening (19) penetrates the wall of this housing (4); both openings (18, 19) are disposed axially at a distance from each other. A pressure sensor (22, 23) is linked to each opening (18, 19).

IPC: G01N1/22
Filed: 1998-03-13
Abstract: A device for carrying out solid phase microextraction is a tubular member (40) having one closed end (44) and one open (42) end with an extracting surface (50) within said tubular member. The extracting surface (50) can be an extracting phase coating extending over a zone within the tubular member (40).

Title: Rotatable joint for a liquid quenching drum
Inventor: SCHMIDT MICHAEL A
IPC: C21D1/63
Filed: 1999-03-18
Abstract: The liquid quenching system (20) for heat treating small parts discharged from a furnace includes a bearing (210) and bearing support (231) that provide cantilevered support to a rotary quenching drum (53). A rotatable joint (202) that rotatably connects the rotary quenching drum (53) to a transfer chute (35) does not provide the majority of support for the rotary quenching drum (53). Accordingly, the rotatable joint (202) can comprise no bearing at all or can be an inexpensive, easy to manufacture bearing or other juncture device. A  protection member (201) is connected to the output end of the transfer chute (35) and protects the rotatable joint (202) from damage from contact with metal parts that are being quenched.
