Abstract: A distributed client/server computer network wherein the identity of at least one complex image, selected from a plurality of complex images stored by a client, is transmitted to a remote server. The remote server then determines, from the identity of the or each image selected, whether the client is authorised to gain access, via the server, to a particular network resource. The network is thus efficient, as the complex images themselves do not need to be transmitted from the client to the server, and secure, as no authorization information is stored by the client.

Abstract: Compositions and methods for secreting large heterologous polypeptides are described.

Abstract: A bonnet lock mechanism for a blowout preventer including an angled surface disposed in the blowout preventer, a latching dog having a tapered surface disposed in the bonnet, and a lock actuator operatively coupled to the latching dog. The the lock actuator is adapted to move the latching dog such that the latching dog is in locking engagement with the angled surface of the blowout preventer.

Abstract: A bonnet lock mechanism for a blowout preventer that includes a radial lock. A radial lock displacement device is coupled to at least one lock actuator. The radial lock displacement device is adapted to radially displace the radial lock to lock a bonnet to a body of the blowout preventer. A bonnet lock mechanism for a blowout preventer that includes a radial lock positioned in a body of the blowout preventer. At least one lock actuator is coupled to the radial lock and is adapted to radially displace the radial lock to lock a bonnet to the body of the blowout preventer.

Abstract: A rotatable mount for a blowout preventer bonnet. A slide mounting bar is slidably couples to a body of the blowout preventer. The slide mounting bar is adapted to move along an axis of a side opening of the body of the blowout preventer. A swivel is coupled to the mounting bar and to the bonnet. The swivel is adapted to enable rotation of the bonnet when the bonnet is disengaged from the body of the blowout preventer.

Abstract: A sidewall passivation layer is deposited on an etched feature in a semiconductor substrate with a hydrocarbon deposition gas by introducing H2, determining certain mixture percentages for the hydrocarbon gas/H2 mix at which the etch rate for the substrate peaks, the etch rate begins to rise from a generally steady state, and/or the etch rate falls to zero, and then maintaining the mixture percentage within a selected range. Where the hydrocarbon gas/H2 mix is maintained at a percentage between the steady-state etch rate percentage and the peak etch rate percentage, then relatively high ion energies are used. Where the hydrocarbon gas/H2 mix is maintained at a percentage between the peak etch rate percentage and the percentage where the etch rate falls to zero, then relatively low ion energies are used.

Abstract: This invention relates to methods for treatment of semiconductor substrates and in particular a method of etching a trench in a semiconductor substrate in a reactor chamber using alternatively reactive ion etching and depositing a passivation layer by chemical vapour deposition, wherein one or more of the following parameters: gas flow rates, chamber pressure, plasma power, substrate bias, etch rate, deposition rate, cycle time and etching/deposition ratio vary with time.

Abstract: An auxiliary seat for young children, particularly for use with children having physical disabilities, is removably connected to the bowl of a toilet. The seat base is a rear-facing horseshoe shape, with upstanding arms and back support. The auxiliary seat provides postural support, by way of contoured sitting surfaces, a deep contoured anterior support. The anterior trunk support is pivotally connected across the front of the seat, to support the trunk and forearms of the user. A separate, adjustable height footrest is provided, the seat having restraint straps that may be individually applied about the knees of the user. A flexible urine deflector is removably insertable at the front of the seat.

Abstract: A connector for connecting opposing ends of a pair of optical fibers inclng a movable, spring biased male contact secured to one end of a fiber and a fixed female contact secured to the opposing end of another optical fiber, the contacts having complementary configured mating surfaces, whereby the opposing ends of the optical fibers are accurately positioned and aligned.

Abstract: An identification system intended primarily for use by Police Forces and Police Departments and other organizations in the field of criminal investigation, the identification system making use of first and second pluralities of photographic facial portions, each portion bearing one or more facial characteristics, said first and second pluralities respectively incorporating portions to enable full front face views and corresponding profile face views to be assembled, the portions in said first and second pluralities being in the same geometric scale and each carrying indicia so that the selection of a photographic portion from one of said pluralities automatically enables the selection of the corresponding photographic portion from the other of said pluralities, whereby both a full front face photographic assembly and a corresponding profile photographic assembly of the facial features of a recollected person can be composed by a witness who recalls said person.

Abstract: A tray assembly for the delivery and service of foods, such assembly including base and cover sections having a plurality of opposing recesses for enclosing a number of dishes, cups, and other utensils needed for a complete meal service. Proper vertical alignment of the two sections as they are fitted together is facilitated by corresponding lateral indentations in the side walls of both parts which serve in manual guiding of the cover into position upon the base, and by arcuate shoulders spaced circumferentially about a generally central recess in one of the sections, such shoulders being received in a complementary channel in the other section. Lugs disposed within the channel are received in notches between the arcuate shoulders only when the cover and base sections are in precise rotational alignment.
