Title: Casting
IPC: B22D18/04
Filed: 1986-02-21
Abstract: A method of making a casting comprising the steps of, at a casting station, feeding molten metal from a primary source (10) of molten metal (11) into a mould cavity (15) through an ingate (49) below the top of the mould cavity, placing the cavity out of feeding relationship with the primary source by changing the orientation of the cavity relative to the force due to gravity to prevent flow of molten metal from the cavity towards the primary source and to permit of flow of metal from a secondary source (42) to the cavity, the cavity being continuously connected to the primary source during said change of orientation, transferring the mould cavity to a cooling station spaced from the casting station and, at the cooling station, permitting molten metal to flow to the cavity from the secondary source whilst the metal in the cavity solidifies.

Patent GB-8814471-D0 (GB)
Title: Security enclosure
IPC: G06F1/00
Filed: 1988-06-17
Abstract: A security enclosure is formed from layers of flexible material. One layer (11;18) carries a flexible semiconductive line (10,13) arranged to extend over the whole area of the enclosure. Any interruption of the line by unauthorised opening of the enclosure changes the resistance of the line and so can be detected by a monitoring circuit. Further, two layers (17) of semiconductive fibres also cover the whole area of the enclosure and are separated by an insulating layer (16). The length of the fibres is greater than the thickness of the insulating layer (16) so that if the enclosure is pierced fibres from one layer (17) will be forced into contact with fibres from the other layer (17). This will change the combined resistance of the layers and this can also be detected by a monitoring circuit. The two measures can be used separately. <IMAGE>

The composition is suitable for use as a retention/drainage agent in paper or paperboard production, preferably after the addition of a conventional high molecular weight flocculating agent.
Patent GB-8902746-D0 (GB)
Title: Communications network
IPC: H04Q3/52
Filed: 1989-02-08
Abstract: A communications network in which a central switching node (70) has at least two sets of both input ports (52) and output port (56) coupled to respective sets of transmitters (Tij) and receivers (Rij) by passive optical networks (54) and (58) and demultiplexers (52) and multiplexers (59). The transmitters (Tij) are tunable so that each can be selectively coupled to one of the input ports (52). The receivers (Rij) are also tunable so the output ports (56) can be selectively coupled to the one or more of the receivers (Rij). Alternatively, the demultiplexers (55) and multiplexers (59) can be tunable. This devolves some of the switching function outside the central switching node (50) thereby reducing the component count.

Title: Silicon-on-insulator capacitive surface micromachined absolute pressure sensor
IPC: G01L9/00
Filed: 1994-03-21
Abstract: A method and structure for forming a capacitive transducer having a deformable single crystal diaphragm. A first well region is formed within a semiconductor substrate in an SOI wafer having a sacrificial layer of known thickness and a top single-crystal silicon layer thereon. Next, a silicon epitaxial layer is deposited on the top silicon layer for forming a flexible single crystal membrane. The epitaxial layer and the sacrificial layer are masked and etched to define the flexible diaphragm. An electrical insulating conformal support layer is deposited on the substrate and attached to the diaphragm so as to seal the sacrificial layer therebetween. An access opening is etched through the diaphragm, and then a wet etchant is inserted through the access opening for removing the sacrificial layer, thereby defining a diaphragm cavity between the remaining epitaxial layer and the substrate. The thickness of the diaphragm cavity is substantially equal to the thickness of the sacrificial layer removed from the SOI wafer. Conductive ions are diffused into facing sections of the diaphragm and the first well of the substrate so as to define fixed and deformable electrodes of the sensing capacitor. Next, a plug is selectively deposited within and for sealing the access opening without substantially reducing the volume of the diaphragm cavity. In this manner, a deflection of the flexible diaphragm in response to variations between the ambient pressure and the pressure sealed within the diaphragm cavity causes a o corresponding change in the capacitance between the first well region and the conductive region in the diaphragm. A reference capacitive sensor of similar construction is also provided for ratiometric pressure measurements. A pressure transducer manufactured in accordance with this process is also described.

Patent GB-9502376-D0 (GB)
Title: Hydrodynamic torque converter
IPC: F16H61/14
Filed: 1995-02-07
Abstract: The housing of a hydrokinetic torque converter in the power train between the engine and the transmission of a motor vehicle contains a lockup valve which can be engaged to transmit torque directly from the output element of the engine to the output member of the turbine in the housing. Engagement of the lockup clutch at a relatively low RPM of the engine and/or under certain other circumstances is prevented or minimized by the provision of one or more valves which are designed to establish or to at least partially seal one or more paths for direct flow of hydraulic fluid between two compartments forming part of a chamber in the housing of the torque converter and being disposed at opposite sides of the axially movable piston of the lockup clutch. The valve or valves can be designed to react in response to changing RPM of the housing of the torque converter, in response to changes of the temperature of hydraulic fluid in the housing and/or in response to changes of the viscosity of such fluid. The valving element or elements of the valve or valves can be caused to change its or their position(s) relative to the respective path(s) in response to the action of centrifugal force and/or due to direct contact with hydraulic fluid in the housing of the torque converter.
