Filed: 1992-10-08
Granted: 2003-06-10
Abstract: A cabinet is provided with a curved, upwardly-swinging door and interior shelves. The curved shelf door is mounted on a pair of opposed pivot arms which rotate on a horizontal axis. Each pivot arm is provided with a disk portion having a central boss and an arm portion tangent to the disk portion. The central boss engages a fixed stud at the side of the cabinet and provides a center pivot for each of the arms. A gas spring for each arm is provided, which is pivotably connected at one end to the arm and at the other end to a side wall of the cabinet. The gas spring serves a dual purpose of counterbalancing the door as it moves between an open and a closed position and opening the door unassisted once the user initiates move-ment of the door, this opening feature being very benefi-cial to seated and physically disabled users.

Granted: 1998-09-08
Abstract: Non-intrusive monitoring and analysis of real-time facsimile transmissions is accomplished. Analog impairment measurements are made on the high speed page signal in those transmissions and protocol analysis is made on the low speed control messages in those transmissions. These measurements and analysis are a powerful tool for trouble shooting service problems afflicting facsimile transmissions. Actual customer traffic can be monitored to detect circuit impairments and to evaluate service being provided. Customer complaints can be handled by providing them with a special phone number which may be called to provide the ability to have the facsimile transmission experiencing a problem specially directed through the facsimile analyzer and forwarded to the intended destination while it is being non-intrusively monitored by service personnel whothen can quickly provide the customer with a diagnosis of the problem.
Patent CA-2086631-C (CA)
Title: Oral administration of immunologically active biomolecules and other therapeutic proteins
Inventor: MICHAEL J GABRIEL
IPC: A61K38/22
Filed: 1993-01-04
Granted: 1998-10-06
Abstract: An orally administrable therapeutic protein is provided by combining the therapeutic protein with a stabilizing agent in an aqueous solution. The solution is coated onto nonpareils and microencapsulated with a water emulsifiable enteric coating composition. The microcapsules are orally administered. The coating protects the protein as it passes through the stomach. Upon reaching the small intestines, the basic pH of the intestinal juices will dissolve the coating, allowing the protein to be released and induce antigen specific immune response which has the specificity of the native molecule. The stabilizing agent protects the therapeutic protein from denaturation during the encapsulation process. In addition to being immunogenic, when administered orally, encapsulated allergen has a therapeutic effect in the treatment of human allergies.

Title: Automatic gain control apparatus
Inventor: KINOSHITA NORIHITO
IPC: H04B1/713
Filed: 1994-06-01
Granted: 1998-08-25
Abstract: An automatic gain control apparatus comprises a variable gain amplifier 5 amplifying a signal with an amplification factor and a gain controller 6 controlling the amplification factor of the variable gain amplifier 5. A gain limiter 7 is provided for restricting the magnitude of said amplification factor within a predetermined range. The amplification factor therefore does not vary largely, even immediately after the input signal level is suddenly changed due to switching of transmitter antenna or carrier frequency. Thus,  it becomes possible to quickly respond to the change of input signal without  requiring  a  large  dynamic  range  in the  circuit following the automatic gain control apparatus.

Abstract: The purpose of the nitriding process is to impart to articles made of ferrous metal, besides the surface properties resulting directly from the nitriding, a corrosion resistance comparable to that which is obtained by following the nitriding treatment with an oxidation treatment, especially in salt baths. According to the process of the invention the articles are treated by immersion for an appropriate period in a molten salt bath consisting in a manner known per se essentially of alkali metal cyanates and carbonates and containing a small quantity of a sulphur-containing species, the articles are raised, in relation to a counterelectrode immersed in the bath, to a positive potential such that a substantial current passes through the bath from the articles to the counterelectrode, and the content of cyanides formed in a secondary reaction is maintained at a value lower than 6 %. It is preferable to work at a constant average current; typical current densities are from 300 to 800 amperes per m<2>, the typical range of temperatures 450-650 DEG C, and the typical times range between 10 and 150 min.

Patent CA-2136615-C (CA)
Inventor: GUIDA ALLAN ABRAHAM
IPC: H04L27/00

Granted: 2003-07-22
Abstract: An encoding scheme resistant to transmission errors encodes a data bitstream for application to a quadrature amplitude modulator (QAM) in a high definition television system. The error-resistant code provides a rotationally symmetrical 32-point constellation on a plane defined by I, Q quadrature axes. The constellation is divided into first (A) and second (B) partitions ar-ranged so that constellation points that are closest in distance to any constellation point of the first partition belong to the second partition, and constellation points that are closest in distance to any constellation point of the second partition belong to the first partition. The binary value of one bit of each of successive 9-bit packets in the bitstream determines that one of the two partitions (A, B) to which both of a consecutive pair of first and second constellation-point transmissions belong (the first and second trans-mitted constellation-points of that consecutive pair being selected by the then current 9-bit packet of the stream). The code is such that the binary values of such one bit of each of alternate ones of the successive 9-bit packets are opposite to one another. This permits a receiver decoder to decide whether each received constellation-point belongs to a first or a second constellation, thereby permitting the detection and, in most cases, the correction of transmission errors.
