Title: Method of manufacturing a microweavable flatware article made of synthetic material, the article produced thereby and an ink-imprinted film component for use in making the flatware article
Inventor: WU CHING CHONG
IPC: H05B6/64
Filed: 1996-09-05
Abstract: A method of manufacturing a flatware article, such as a dish or cup that is decorated with a multi-colour design embedded in a food contacting surface of the article. The flatware article can be used in a microwave oven without causing deterioration of the multi-colour design, such s fading, bubbling or emission of harmful toxic fumes. The method comprises injecting molten polycarbonate material into amould where is positioned a transparent film imprinted with the design. The filmbonds with the polycarbonate material to form a laminated structure. The ink impression is applied on a surface of the film that bonds with the polycarbonate so the ink is embedded in the laminated structure and it is thus protected from scratches and contact by foods. The invention also extends to a novel flatware article.

IPC: F16D3/41
Filed: 1997-04-30
Abstract: A universal joint assembly includes a cross having a body and at least a pair of outwardly extending opposed trunnions. The trunnions define a trunnion axis. A bearing cup is rotatably mounted on each of the trunnions. A yoke includes a pair of opposed arms wherein each arm has an opening formed therethrough and aligned with the other arm opening to receive one of the bearing cups.

IPC: H04B1/12
Filed: 1997-05-15
Abstract: A noise suppression circuit for a two-wire communications channel comprises a hybrid device, for example a hybrid transformer or circuit, for providing a differential output signal corresponding to a received signal in the two-wire channel. A summing device extracts from the two-wires of the channel a common mode signal and supplies it to a noise estimation unit which derives from the common mode signal an estimate of a noise level in at least one sub-band having a bandwidth considerably narrower than an operating bandwidth for the channel. An amplifier adjusts the amplitude of the noise estimate to correspond to the residual noise in the differential output signal. It is then subtracted from the differential output signal. A noise detection and control unit scans the operating band, identifies a sub-band having an instant highest noise level, and sets the noise estimation unit to the detected sub-band. The noise estimation unit suppresses the noise in that sub-band. In preferred embodiments, the noise estimation unit comprises several channels, each comprising a tunable filter, a phase shifter and an amplifier and the noise detection and control unit sets the channels, in succession, to different sub-bands in descending order of noise level.
