Title: Hybrid public key algorithm/data encryption algorithm key distribution method based on control vectors
Inventor: MATYAS STEPHEN M
IPC: H04L9/08
Filed: 1992-05-12
Abstract: The  patent  describes  a  method  and  apparatus  for securely distributing an initial Data Encryption Algorithm (DEA)  key-encrypting  key  by  encrypting  a  key  record (consisting   of   the   key-encrypting   key   and   control information associated with that key-encrypting key) using a public  key  algorithm  and  a public  key belonging  to  the intended recipient of the key record.  The patent further describes a method and apparatus for securely recovering the distributed  key-encrypting  key  by   the   recipient  by decrypting the received key record using the same public key algorithm and private key associated with the public key and re-encrypting the key-encrypting key under a key formed by arithmetically combining the recipient's master key with a control vector contained in the control information of the received key record.   Thus the type and usage attributes assigned by the originator of the key-encrypting key in the form of a control vector are cryptographically coupled to the key-encrypting key such that the recipient may only use the received key-encrypting key in a manner defined by the key originator.  The patent further describes a method and apparatus to improve the integrity of the key distribution process by applying a digital signature to the key record and  by  including  identifying   information  (i.e.,   an originator identifier) in the control information of the key record.   The  integrity  of  the  distribution  process  is enhanced by verifying the digital signature and originator identifier at the recipient node.

Title: Method for selective cvd diamond deposition
Inventor: IACOVANGELO CHARLES D
IPC: C23C16/04
Filed: 1992-06-25
Abstract: METHOD FOR SELECTIVE CVD DIAMOND DEPOSITION        ABSTRACT OF THE DISCLOSURE Broadly, the present invention is directed to a method for the selective deposition of chemical vapor deposition (CVD) diamond on a surface of a substrate. The method comprises the steps of masking an area of said surface not to be coated with CVD diamond with a coating material that prevents CVD diamond formation. The substrate then is subjected to a CVD diamond deposition process for coating a layer of CVD diamond on the substrate in the unmasked areas only. Advantageously, the surface first is coated with a layer of material that promotes CVD diamond formation and then the coated substrate is subjected to the masking step of the method. Advantageously, the substrate comprises a twist drill wherein the surfaces perpendicular to the main shear planes involved in drilling, such as the planes forming the cutting edge of the drill, are coated with CVD diamond while the remaining areas of the twist drill remain uncoated.

Title: Thermoregulatory clothing

IPC: A41D/
Filed: 1990-12-28
Abstract: It is an object of the present invention to provide a means by which clothing may be made more effective in its role in assisting temperature regulation, by: 1) providing in-creased heat exchange by means of reduced insulation (her-ein defined as "lower insulatory capacity") of temperature-sensitive sites (11, 16, 14) - reducing insulation of tempera-ture-sensitive areas not protected by "fat pads"; and/or 2) providing for increased vapour exchange by means of spe-cific ventilation of temperature sensitive areas (herein de-fined as "increased ventilatory capacity") - allowing flexibil-ity for rapid increases in heat generation owing to facility for improved vapour exchange e.g. the loss of excess heated air or humidity, by, for example, convection and evapora-tion of sweat from the surface of the skin.
Patent CA-2076591-A1 (CA)
Inventor: BRADY ROBERT T
IPC: F22B21/26
Filed: 1992-08-21
Abstract: A method and apparatus for low NOX combus-tion of natural gas in a compact steam boiler having output steam delivery controlled by predetermined outlet steam pressure.  The compact boiler employs a small high heat release combustor discharging into a forced draft convective heat exchange section.  In operation, the compact boiler is completely and auto-matically self-operating, employing flue gas recircu-lation (FGR) wherein the FGR is admitted into the burner combustion air through a valve controlled by boiler flue gas NOX content. A novel bell mouthed flue gas scoop is utilized in the boiler stack up-stream of the NOX sensor.  In an alternate combustion chamber design, a cylindrical water wall coil sur-rounds the combustion process, increasing boiler effi-ciency through the inherent large temperature differ-ence between the coil and the combustion in process, along with reducing the combustion temperature and further reducing the NOX content of combustion prod-ucts.  A further variation in the combustion system utilizes a ceramic shield surrounding a natural gas burner as it fires into the compact combustion cham-ber.  Primary and secondary combustion air are admit-ted to the combustion chamber through first stage combustion internal of the shell and second stage combustion occurring internal of the boiler combustion chamber.

Abstract: In a duplicate active-standby memory unit arrangement, a resynchronization initiation determination is made on a cell-interval-by- cell-interval basis based on the equality of cell contents of corresponding queues in the active and standby memory units. If an inequality of the cell contents of the correspondingqueues in the active and standby memory units occurs during any cell interval, resynchronization may be initiated.  In an embodiment, the lengths of data in corresponding queues, i.e., the number of cells stored in the corresponding queues, in the active and standby memory units are compared on a cell-interval-by-cell-interval basis. If the number of cells stored in any of the queues is different than the number of cells its corresponding queue in the other of the memory units during any cell interval, resynchronization of the memory units is initiated. In another embodiment of the invention, the outputs of corresponding queues in the active memory unit and the standby memory unit are compared on a cell-interval-by-cell-interval basis. If the results of the comparison indicates that any one or more of the queue outputs in one of the memory units is different from the output of the corresponding queue in the other memory unit, resynchronization is initiated. Robustness of the latter comparison algorithm is enchanced by restricting the comparisons to cell intervals during which the queue outputs in the active and standby memory units do not both include idle cells. Additionally, robustness of the resynchronization initiation is further enhanced by simultaneously employing both the comparison of cell length in the queues and the comparison of the queue output contents to detect when to initiate resynchronization.

Title: Caramel confections and processes for preparing and using
Inventor: LYNCH WILLIAM R
IPC: A23G3/02
Filed: 1993-10-25
Abstract: Caramel confections which facilitate coating, depositing, molding and baking are prepared from a finely divided solid candy phase dispersed within a continuous fat phase. These products differ from conventional caramel products which are based on sugars and milk protein and typically exhibit a chewy texture but are difficult to mold or to otherwise handle. A powdered caramel brittle material is made by sheeting, cooling and grinding a caramel prepared by cooking aqueous milk solids with sugar to a moisture level of below 6%. Preferably, from 5 to 35% of the powdered caramel brittle is mixed with 30 to 60% granulated sugar, 18 to 30% fat, and 10 to 25% milk solids. The mixture is refined to obtain an average particle size of 0.0004 to 0.0020 inches, mixed with an emulsifying agent and additional vegetable fat, and heated as necessary to reduce the moisture level.
