Patent CA-2032339-C (CA)
Title: A method for melting and/or burning-in layers of ceramic paints
Inventor: ARFSTEN NANNING
IPC: C03C17/00
Filed: 1990-12-14
Granted: 1999-11-16
Abstract: Large area decorations of glazings, ceramic paint or the like on glass ceramic, glass, ceramic or similar meltable substrates, in particular on glass ceramic cooking plates, are applied by the new method by means of a laser beam which is widened linearly over the entire width of the area to be decorated, as it were in a zone melting method. The linear energy supply zone is advanced at a speed high enough for essentially only the decorating material to be melted on or burnt in hut ensuring that the thermal conduction front does not move appreciably into the substrate material.

Title: Cloning host organisms
Inventor: GREENER ALAN L
IPC: C12N15/70
Filed: 1990-12-28
Granted: 2001-07-24
Abstract: Methods and materials fox the cloning of DNA, in particular, for the cloning of "unclonable" DNA using genetically engineered host cells. Host cell organisms have been discovered that stabilize and inhibit rearrangement of DNA molecules capable of forming non-standard secondary and tertiary structures.   Organisms are engineered to contain at least one mutation which inactivates homologous recombination and at least one mutation in a DNA repair pathway. Examples of such DNA pathways include Uv repair pathway, the SOS repair pathway, the mismatch repair pathway, the adaptive response pathway, the heat shock response pathway, the osmotic shock response pathway, the repair pathway of alkylation damage, the repair pathway of uracil incorporation into DNA and pathways involved in maintaining DNA superhelicity.      The host organisms of this invention are suitable for cloning DNA capable of forming non-standard and tertiary structures such as found in eukaryotic DNA.

Title: High-speed a/d conversion using a series of one-bit conversion stages
Inventor: ICHIHARA MASAKI
IPC: H03M1/44
Filed: 1992-06-17
Granted: 1997-10-21
Abstract: In an analog-to-digital converter, one-bit A/D conversion stages are connected in series to receive an analog signal. Each conversion stage includes a sample-and-hold circuit for sampling an analog signal from a preceding stage, a comparator for comparing it with a specified voltage level to produce a logic signal at one of two discrete levels depending on whether the signal received from the preceding stage is higher or lower than the specified level. The signal received from the preceding stage is summed with a prescribed reference voltage of one of opposite polarities depending on the level of the logic signal to produce an analog output signal. The successive conversion stages are driven so that the analog signal from each stage is transferred to the next, and the logic signals generated by the individual conversion stages are delayed so that they appear simultaneously at digital output terminals.

Patent CA-2081167-C (CA)
Title: Redirection of calls by a communication terminal
Inventor: BALES BRUCE MERRILL
IPC: H04M3/42
Filed: 1992-10-22
Granted: 1997-03-25
Abstract: A telecommunication protocol message that allows redirection of a call received by a first telephone station set to a second telephone station set or other terminal equipment by the first telephone station set transmitting the redirect message to a telecommunication system connected to the first telephone station set. The redirect message includes the identification of the user of the first telephone station set as well as the telephone number of the second telephone station set or terminal equipment. The telecommunication switching system is responsive to the redirect message to reroute a call to the second telephone set. The redirect message allows the first station set to transmit only one message to the telecommunication switching system to accomplish the functions of rerouting the call. In addition, the redirect message gives a BRI (basic rate interface) station set the capability of automatically forwarding certain types of calls. Since a call setup message includes the telephone number of the originating station set, the BRI station set can be programmed to transfer calls to different station sets based on the originating station number. In addition, with the proliferation of facsimile machines (often referred to as FAXs), there is a problem in coordinating an individual's telephone number with the individual's FAX number by a person wishing to send a FAX. Using the redirect message, the BRI station set can be programmed to examine the bearer capability information encoded as an Information Element, IE, in the setup message to determine the type of call that is being set up. If a digital data call is being set up, the BRI station set then examines the higher layer capability IE in the setup message to determine whether or not it is a FAX message. If it is a FAX message, the BRIstation set will automatically forward the call to the FAX designated by the user of the BRI station set. Further, the station set will display a message indicating that a FAX message had been forwarded. Using this technique it is only necessary to know a person's telephone number in order to send a FAX to that person.
