Patent CA-2063224-A1 (CA)
Inventor: HACHINOHE YUTAKA
IPC: F25D3/02
Filed: 1992-03-17
Abstract: The low temperature food storage equipment of the present invention is provided with an icehouse and a food storeroom each surrounded by a heat insulator.  The icehouse and the storeroom are connected by a detachable heat exchanger disposed therebetween.  In the icehouse there is stored water which is frozen into ice when the outside air grows cold.  In the storeroom there are kept in cold storage a large amount of shippable food, for example, potatoes.  In the case of shipping the food, the heat exchanger is removed and the food is transported on a truck or the like while being kept in cold storage in the storeroom.

Title: Quasi-duplex radio system using bi-directional hole extension
Inventor: REED JOHN D
IPC: H04W84/08
Filed: 1990-12-12
Abstract: A method for interrupting a radio transmission in a quasi-duplex radio-frequency communication system. The method of the present invention includes the step of transmitting a signal (22), with periodically-occurring holes (24) therein, by a first communication unit (10) to at least a second communication unit (12). The transmitted signal (12) includes an audio information portion (16) and information packets (23). Each information packet (23) specifies the time of occurrence of the next hole (24). The second communication unit (12) initiates an interruption of the transmission made by the first communication unit (10) by transmitting an interrupt request signal (31) to the first communication unit (10) at a time specified by an information packet (23) received by the second communication unit (12). When the first communication unit (10) receives the interrupt request signal (31), it processes the interrupt request signal (23) to determine whether it complies with predetermined criteria. If the first communication unit determines that the interrupt request signal complies with the predetermined criteria, it transmits an acknowledgement signal allowing the second communication unit (12) to interrupt the transmission so that the second communication unit (12) may begin transmitting information to be received by at least the first communication unit (10).

Title: Probe for blood gas sensing
Inventor: TOMISAKA DENNIS M
IPC: A61B5/1459
Filed: 1990-09-25
Abstract: 2065452 9105513 PCTABS00005 In a blood gas sensing probe, a cylindrical sleeve (42) contains an optical fiber (40). The end (45) of the optical fiber is withdrawn into the sleeve thereby creating a receptacle (51) at the end of the sleeve. A sensitive dye (5), HOPSA for example, is encapsulated in a gel and deposited in the receptacle (51) to form the probe. In making the probe, the end of the optical fiber is in the same plane as the end of the sleeve in which it is placed. The dye and gel contact the combined ends of optical fiber and sleeve. The fiber is withdrawn into the sleeve thereby creating a vacuum which is filled by the dye and gel.

Title: Process for correcting the reference flux of a converter-powered multi-phase machine and circuit for implementing the process
Inventor: HUGEL HARALD
IPC: H02P21/06
Filed: 1990-07-17
Abstract: Abstract The invention relates to a process for correcting a pre-controlled reference flux (?w) for a field-oriented control containing a reference voltage model (16) of a converter-powered multi-phase machine (4) with a speed detection device, and to a circuit for implementing the process.  According to the invention, a comparison between a reference voltage (¦Uw¦) used as a setting for the converter (24) and a predetermined maximum converter output voltage (Uwmax) provides a voltage control difference (Ue) from which, by means of a flux correction controller (48), a flux control value (?x) is generated, which reduces the pre-controlled reference flux (?w) until the reference voltage (¦Uw¦) for the converter (24) is lower than or equal to the predetermined maximum converter output voltage (Uwmax). Thereby the field-oriented regulation never leaves the field-oriented range.            Figure 3

Patent CA-2069003-A1 (CA)
Title: Remote access telephone control system
Inventor: MANOWSKI MAXWELL E
IPC: H04M1/00
Filed: 1990-11-16
Abstract: A telephone control system (1) which enhances the accessibility of system subscribers by providing a variety of call-handling modes, and various ways of programming by which those subscribers can tailor the system. In operation, subscribers are each assigned a telephone number (ACCESS      NUMBER) which can be dialed from any location via the Public Switched Telephone Networks (PSTN) (2). The control system determines which subscriber a call is intended for, and by referring to a data base determines the method of call handling which has been preselected by that subscriber (e. g. switching a call to another telephone number ). The switching function (4) may be located in the control system itself, or located in the PSTN but under the control of the control system. Hence the ACCESS NUMBER may be used as the sole telephone number for a subscriber. Callers need not know the subscribers specific whereabouts nor the subscriber's various location-specific telephone numbers such as home, office, car phone, and so forth.

Abstract: A method for controllably dissolving a crystalline material consisting of several kinds of ions in a solution containing a solvent for the crystalline material. Before dissolution, said solution contains at least two kinds of ions of the crystalline material. The molar concentration of each kind of ion is greater than zero but lower than the molar concentration of each kind of ion which the solution would have when saturated, if it contained all the ions making up the crystalline material, under the temperature and pressure conditions of dissolution. Said method can be used for the chemical milling of piezoelectrical materials, particularly berlinite.

Title: Method for obtaining thick, adherent diamond coatings using metal interface screens
Inventor: KEHL RANDALL J
IPC: C23C16/04
Filed: 1992-08-13
Abstract: METHOD FOR OBTAINING THICK ADHERENT DIAMOND    COATINGS USING METAL INTERFACE SCREENS                Abstract of the Disclosure Broadly, the present invention is addressed to a method for coating a substrate with a layer of chemical vapor deposition (CVD) diamond. The inventive method comprises attaching a screen to the area of the substrate to be coated and coating said screened area with a layer of CVD diamond. Preferably, the screen is attached only at its edges by spot welding or arc welding the screen to the area of the surface where the diamond coating is desired. The screen serves two functions: it creates a more favorable surface for diamond deposition; and it provides a semi-flexible surface that aids to relax stresses that occur in the diamond film both during growth and during cool down to room temperature. The screen may be made from carbide-forming materials, such as Mo or W, to create a surface that is more favorable for diamond growth. Upon cooling, the fine screen distorts to relieve the compressive stresses that occur in the film due to diamond's low coefficient of thermal expansion Although the diamond may not be in direct physical contact with the underlying substrate, a good physical bond is provided by the welding process, thereby allowing the diamond film to remain intact and serve as a protective coating. Accordingly, the resulting screened substrate with a layer of CVD diamond overlaying the screen comprises another aspect of the present invention.

Each unit receives from a preceding unit an access request word comprising a plurality of successive request channels to which priorities are assigned and writes its own priority in the corresponding request channel.  The request word is then transmitted to a following unit.  When no preceding unit has a priority exceeding the priority of the considered unit, these preceding units are inhibited from accessing the communication channel.  When after a predetermined time interval, the considered unit is not inhibited by any of the following units. it may access the communication channel.
