IPC: B29D11/00
Filed: 1996-02-21
Abstract: Methods of deblocking a polymeric article from a mold and/or removing undesirable materials from a polymeric article by applying supercritical fluids to the polymeric article. A preferred process is the treatment of ophthalmic lenses, such as contact lenses. Supercritical fluid, composed primarily of carbon dioxide, is applied to a contact lens affixed to a mold subsequent to the polymerization step. The application of supercritical fluid (SCF) causes the lens to efficiently and consistently separate from the mold, removes undesirable materials such as unreacted monomer, oligomers, or residual solvents from the lens core, and/or cleans the lens surface of adhered debris.

The covering material is greater in width than the sum of the widths of the top and two side surfaces, so that the edges of the formed covering material extend beyond the mineral fiber core. A vacuum is applied below the mineral fiber core to draw the formed covering material extending beyond the side surfaces under the core.

Title: Echo suppressor and non-linear processor of echo canceller.
Inventor: KIRLA OLLI
IPC: H04M1/60
Filed: 1997-06-05
Abstract: The invention relates to an acoustic echo suppressor and a non-linear processor for an echo canceller in a 4-wire data transmission network. An echo canceller is typically controlled by comparing the power levels of the near-end and far-end signals. The transfer function of an acoustic echo path is usually very non-uniform. According to the invention, the spectrum of the far-end signal is treated, before the signal power level is calculated, with a weighted filter, which models the effect of the transfer function of acoustic echo. As a result, the double talk dynamics is improved, since high-energy vowels of far-end speech, which normally cause low-energy vowels of near-end speech to be clipped in an echo suppresseor, will be attenuated.

Title: Transponder interface
Inventor: SHARRATT MICHAEL
IPC: H04Q11/00
Filed: 2000-02-18
Granted: 2002-09-11
Abstract: The invention provides a transponder interface (1400,) for an optical communication system comprising a plurality of mutually interconnected bi-directional optical waveguide rings (20, 30, 40, 50, 60) in which radiation modulated with communication traffic propagates. The radiation is partitioned into 32 distinct wavebands. Interfaces (70, 80, 90, 100, 110, 120, 1200, 1400, 1500) are included in the system where communication traffic propagating in the rings transfers from one ring to another. Each interface (70, 1400, 1500) is capable of providing an all-optical waveband reconfigurable communication link between the rings (20, 30, 40, 50, 60). At each interface (70, 1400, 1500), conversion of optical radiation to corresponding electrical signals is not required when transferring communication traffic from one ring to another and from waveband to another, thereby providing the system with a potentially larger communication bandwidth compared to conventional optical communication systems. Radiation passing through the interface (1400) may have its wavelength changed in transponder (1410).

Title: Amplifier circuit
Inventor: FORSTER IAN JAMES
IPC: H03F3/60
Filed: 2000-05-16
Granted: 2001-08-01
Abstract: An amplifier circuit for amplifying an input signal to generate an amplifier output signal incorporates a cascaded series of reflection amplifiers arranged along a signal path and operative to amplify signals propagating in a forward direction along the signal path. The circuit is operative to counteract signal propagation in a reverse direction along the signal path, thereby hindering spontaneous oscillation from arising within the circuit. Incorporation of reflection amplifiers into the circuit enables it to provide high gain, for example 50 dB, while consuming low currents, for example, tens of microamperes. The circuit is especially suitable for use at intermediate frequencies in radio receivers such as mobile telephones.

Title: Vacuum storage compartment construction in a cooling apparatus body
Inventor: NAYLOR SIMON JAMES
IPC: F25D23/12
Filed: 2004-07-02
Granted: 2007-04-11
Abstract: A cooling apparatus body ( 11 ), for example, for a refrigerator ( 10 ), has a first compartment ( 15 ) intended for storage of items at atmospheric pressure and a second compartment ( 16 ) for storage of items at subatmospheric pressure, the two compartments being surrounded by surrounds formed by a thermal insulation element ( 13 ).

The liner ( 23 ) can be an integrally formed box-shaped component produced by, for example, injection moulding or blow moulding from plastics material. The resistance of the liner ( 23 ) to the internal load of subatmospheric pressure is provided primarily by the thermal insulation lining surround and the bond therewith, so that the liner, whilst providing a hermetic barrier relative to the surround, can be of inexpensive lightweight construction.

Title: Method for the manufacture of gold-coloured coatings
IPC: C23C14/00
Filed: 1978-12-15
Granted: 1982-10-27
Abstract: A method of producing gold-color coatings on substrates by evaporating a coating material comprising a metallic titanium or zirconium in a housing which has walls which define an evaporation space, comprises, maintaining a vacuum atmosphere containing N2 and argon in the space. The method is carried out using an anode connected to a power source to produce a low voltage arc discharge in the vicinity of the coating material which is arranged within the evaporation space and also maintaining a low voltage arc between the anode and the substrates. A potential difference between the anode and the substrates of a range of between 5 v and 100 v are maintained during the process and, in addition, the electrical potential of the substrates is maintained between 0 and 150 volts lower than the potential of the housing walls which define the evaporation space. The substrate to be coated is coated at a rate of from between 1 to 15 nanometers per second. The N2 and argon atmosphere is maintained so that a partial pressure of the N2-containing component ranges between 2x10-4 and 10-2 millbar. The potential difference between the anode and the substrates is reduced in the course of the process to release the sputtering threshold of the substrate and the housing wall. The partial pressure of the N2-containing components continuously increase in the course of the process.
