Patent CA-2014868-A1 (CA)
Inventor: JONES RICHARD P
IPC: G06F21/00
Filed: 1990-04-19
Abstract: The invention is a system for protecting the security of computer files. It has hardware elements, including a programmable auxiliary memory and control unit alomg with associated software elements. The security subsystem is installed on the host computer bus so that it resides in the control logic, address, and data signal path between the computer storage device and central processing unit. The security system is accessible by the computer operating system only during installation and initialization. Thereafter it is inaccessible to or by the operating system. Supervisor determined criteria for access permission to read, write and execute files are entered into the auxiliary memory system where they are protected from alteration. The security system will deny access to users with invalid entry criteria and refuse to write data to the file storage device when unauthorized operations have been performed. When breaches of these types occur the security system can lock the computer against further activity until it is released by entry of a master password from supervisory or security personnel. The system maintains a protected area in the computer memory device where, among other data, file signatures of all valid files are retained. The protected area of memory also maintains appropriate signatures of all internal files in the security system so that they can be automatically checked for integrity.

Patent CA-2019585-A1 (CA)
Inventor: KEM HAN
IPC: G06F13/42
Filed: 1990-06-21
Abstract: The circuit of the present invention provides a signal which allows data to be transferred between a first synchronous system to a second synchronous system.  Where the first synchronous system is a Time-Division-Multiplexing (TDM) system and the second synchronous system is a Microprocessor system.  The transfer is allowed at the end of the assigned time slot provided that the microprocessor is not accessing the data.  If the microprocessor is accessing the data, then the transfer is delayed for three clock cycles of the TDM clock.  After the delay, if the microprocessor is still accessing the data, the transfer is delayed again.  The delaying continues until the microprocessor is no longer accessing the data, at which time the transfer is allowed.

Abstract: A simple, operationally reliable and economic process is described for decaffeinating green coffee, which ensures a high degree of decaffeination, avoids denaturation of further constituents of the green coffee and permits isolation of the caffeine. In this process, green coffee beans, optionally moistened to 20% by weight to 40% by weight, are first extracted with a carbon dioxide-saturated liquid solvent, preferably water, at a temperature of 20 DEG C to 110 DEG C and at a pressure of 30 bar to 300 bar and, after reducing the pressure to 1 bar to 10 bar, are rinsed with the liquid solvent. The liquid phase loaded with the green coffee constituents including caffeine is decaffeinated in a device provided downstream by treatment with supercritical carbon dioxide and is again saturated with CO2. The caffeine is washed out of the supercritical CO2 phase with water and is isolated in pure crystalline form. <IMAGE>

Filed: 1991-01-17
Abstract: A method and apparatus for forming and selectively interrupting one or more fluid stream which is confined within an open channel. A transverse fluid stream is introduced into the channel at a point under the stream flowing within the channel. Introduction of the transverse stream at relatively low pressures is sufficient to cause the stream within the channel to leave the confines of the channel. If the channel is directed at a target, the method and apparatus will allow intermittent and selective interruption of a fluid stream flowing within the channel and directed at the target. The source of the transverse fluid stream has an arcuate or curved outlet portion to prevent fluid from the open channel from accumulating therein.

Title: Firearm training system and method
Inventor: WONG JOHN D E
IPC: F41A33/00
Filed: 1991-05-14
Abstract: ABSTRACT      A firearm training system is disclosed, which allows the measurement and display as a function of time of the hand grip forces applied to the grip of a firearm by a weapon hand of a shooter.  This permits the detection of variations in the hand grip forces during firing of the weapon.  This firearm training system also provides for the detection and display as a function of time of the position of the firearm trigger.  The system includes separate force transducers for the side and front grip forces applied to the side surfaces and the front surface of the grip respectively as well as a trigger position sensor.  A relative value of the hand grip forces detected by the transducers and a relative trigger position detected by the sensor are graphically displayed by the system as a function of time.  Further disclosed is a method of training a shooter by determining the grip pattern of the shooter's weapon hand on a firearm having a grip and a trigger.  The method includes detecting a front grip force and a side grip force applied by the weapon hand to a front surface and a side surface of the grip respectively and graphically displaying as a function of time a relative value of the front grip and side grip forces respectively.  Thus, the system provides for a more effective training of a shooter, which substantially translates into cost savings in terms of training time and ammunition, especially since the firearm training system and method may effectively be used under dry as well as live firing conditions.

Abstract: ABSTRACT    An aqueous coenzyme reagent composition contains NADH, a carbonatetbicarbonate buffer (with a pH of about 9.5 - 11) and water.  Both NADH and the buffer are at low concentrations, e.g., about 2 - 5 mM for NADH and about 2 - 15 mM for carbonate/bicarbonate. When this coenzyme reagent is mixed with an enzyme reagent, the mixture achieves a neutral pH.  The combination of high pH, low NADH concentration and low buffer concentration permit the aqueous reagent to be stored for extended periods at low temperatures without NADH degrading to form impurities which interfere with or inhibit enzyme activity, such as the activity of lactate dehydrogenase or malate dehydrogenase in an assay for ALT or AST.

Title: Buoyancy body primarily for use on large sea depths, and a method of manufacturing such a body
Inventor: NIELSEN OVE H
IPC: A01K75/04
Filed: 1990-02-27
Abstract: ABSTRACT OF THE DISCLOSURE          In order to hold trawl bags open during trawling use is made of buoyancy bodies connected with the top edge of the trawl mouthing.  When working on large sea depths the air filled buoyancy bodies are exposed to excessive pressures which they can hardly resist when they are made as hollow bodies.  The are better off if made of a cellular plastic with small cells, but since they are shaped as balls of a considerable size it is almost impossible to control such a production so as to end up with a production without large cavities. According to the invention the buoyancy body is an assembly of smaller parts formed in a manner such that they have no large thickness anywhere, and when these parts are produced individually as foam plastic parts it is possible to achieve the desired small cell structure thereof.  With the illustrated design it is possible to provide a solid foam plastic ball from only two parts, without these parts at any place having a material thickness that is more than just a fraction of the ball diameter.

Abstract: VIBRATING BEAM TRANSDUCER DRIVE SYSTEM                   Abstract of the Disclosure A drive system (40) for providing different excitation voltages to the separate beams (16, 18) of a multiple beam vibrating transducer (12) is disclosed. In one embodiment of the invention an amplified voltage at the resonant frequency of a master beam (16) is amplified and applied to a secondary beam, to force the secondary beam (18) to vibrate at the resonant frequency and amplitude of the master beam (16) to force the transducer to resonate at the frequency of the master beam (16). Since the transducer (12) vibrates at the resonant frequency of one of the beams, the transducer energy losses to the adjacent mounting structure are reduced. This results in a higher transducer quality factor so that frequency shifts in the resonant frequency can be readily measured as changes in the parameter that the transducer (12) is intended to monitor.
