Patent EP-0050904-A1 (EP)
Inventor: SCALES JOHN MICHAEL
IPC: E02B3/14
Filed: 1981-10-28
Abstract: A cellular precast grid and mat for use as revetment. The grid, which may typically be cast of concrete, is substantially rectangular, having a flat bottom and, in its middle, two optional vertical openings of rectangular cross section with two inwardly sloping sides. The grid also has two vertical U-shaped channels on each longer opposed side and a two-tier vertical channel on each shorter opposed side, which vertical channel can accept projecting portions of the shorter side of two like grids positioned in abutting relationship, thereby permitting arrangement of grids into revetment of abutting staggered interlocking rows of grids. The grids may be individually placed with or without interconnecting pins or may be interconnected into mats by passing cables through tunnels passing horizontally through the grids parallel to the longer sides. Since such cables pass through staggered grids, parallel cables running in a single direction effectively interconnect grids into an integral mattress of staggered rows of grids to produce articulatable concrete mat revetment which may be used with or without filter means constructed of natural materials or filter fabric or other flexible liquid-permeable membrane.

Abstract: The apparatus 10 employs a collapsible infusate reservoir 14 which is biased toward its collapsed condition to supply infusate under pressure to an outlet catheter 32 via a pair of parallel flow paths 22, 34 having different fluid restriction characteristics. The flow path 34 has a controllable valve 38 and a fluid accumulator 46 is connected to the path 34 upstream of the valve 38 so that infusate can be delivered to the catheter 32 via one or both paths 22, 34 depending upon whether the valve 38 is closed or open.

Abstract: A circuit for generating a reference voltage comprises first and second transistors (Q 1 , Q 2 ) with their bases connected together, the emitter area of the first transistor being smaller than the emitter area of the second transistor. The emitter of the first transistor is connected to ground, and the emitter of the second transistor is connected to the ground via a first resistor (R 1 ). A current mirror circuit (1) supplies equal currents to the collectors of the first and second transistors. A feedback amplifier (2a) extends from the collector of one of the transistors to a first voltage supply (V A ), the feedback amplifier being driven by a second power supply (Vcc) of higher voltage than the first. To reduce the voltage required from the second power supply, a second resistor (R 12 ) is connected between an output terminal and a point connected to the bases of the first and second transistors; and a current generator circuit (Q e ) is connected between this point and ground, to produce a current which is proportional to the emitter current of the first transistor or the second transistor, such that a constant voltage is generated at the output terminal.

Abstract: An apparatus (10) is provided for positioning and driving . toroidal bodies (11) of variable sizes such as sand cores during the building of portions of the body. The apparatus (10) includes a height adjusting mechanism (16) for raising the horizontal mid-circumferential plane (A',A") of the body so that it will intersect the rotational centre (A) of a shuttle (15) which rotates in a plane transverse to the mid-circumferential plane of the body (11). A centering and driving mechanism (17) includes idler rollers (18) and a drive roller (15) whereby the body is positioned and driven with the rotational centre (A) of the shuttle (15) lying not only on the horizontal mid-circumferential plane (A', A") of the body, but also coinciding with the centre of a cross-section of the body formed by a plane of the shuttle (15). A carrier roller aligning mechanism (21) aligns the longitudinal axes of a plurality of carrier rollers (23,24) to intersect with the rotational axis (B,B') of the body to avoid abrasion of the body. A signal turret mechanism (25) with two turrets (26,28) has prepositioned proximity switches (189,215), one of which is actuated so that a flag (220) on the body will signal the starting and stopping of the rotation of the shuttle (15) when the flag (220) passes the actuated proximity switch.

Abstract: A data processing system includes at least two processors, each having a cache memory containing an index section and a memory section. A first processor performs a task by deriving internal requests for its cache memory which also may respond to an external request derived from the other processor which is simultaneously processing a task. To avoid a conflict between the simultaneous processing of an internal request and of an external request by the same cache memory, one request may act on the other by delaying its enabling or by suspending its processing from the instant at which these requests are required to operate simultaneously on the index section or the memory section of the cache memory of the processor affected by these requests. Thereby, the tasks are performed by the system at an increased speed.

Abstract: To detect residual glass, such as appears at semiconductor chip pads and via holes during the fabrication of alumina/glass ceramic substrates that are used as supports for the semiconductor devices, the glass used for forming the ceramic substrates is doped with a rare earth oxide. During the manufacturing process, the ceramic structures are irradiated after firing with radiation of wavelengths in the range 350-500 nm to induce the glass to fluoresce, thereby revealing the residual glass on the surface of the metallic interconnector pads. If residual glass is present, the parts are reworked, or scrapped if necessary.
