Title: Warpable guide vanes for turbomachines
Inventor: BRITT JACK
IPC: F01D5/18
Filed: 1983-10-27
Abstract: An air-cooled variable guide vane for effecting changes in the area of a turbine nozzle throat in a gas turbine engine. Structurally, the aerofoil 58 of the guide vane 48 comprises a load-bearing spine 70 and a thermally warpable skin 72, which includes the trailing edge and which is attached (e.g. by welds 74a,74b) to the spine 70 spanwise of each flank of the aerofoil, but is not attached to the rest of the guide vane. During operation of the engine, differential thermal expansion of the two flanks of the thermally warpable skin 72 with respect to each other relative to their cool state makes the trailing edge of the aerofoil move with respect to the leading edge to cause changes in the area of the turbine nozzle throat T, these changes being regulated by altering the pressure of cooling air using valves (65 Fig. 2, not shown) and directing it onto the interior of the thermally warpable skin 72 via holes 78 in an inner skin 60 of the aerofoil. <IMAGE>

Title: A repairable memory array
Inventor: WALLER DAVID L
IPC: G11C29/04
Filed: 1984-02-08
Abstract: The columns of a memory array are accessed by a plurality of column decoders, each decoder selectively accessing one column in a respective group of columns. Each column decoder can be connected to a respective data line by way of a first transistor, and the data line can also be connected to the decoder of a preceding group of columns by way of a second transistor. The second transistor associated with the first stage can connect the first data line to a spare column decoder accessing a spare group of columns. The conditon of each pair of first and second transistors is controlled by way of a respective normally closed fuse, and generally each column decoder is connected by its first transistor only to its respective data line. However, if defects are found in a group of columns, the associated fuse is blown to isolate that group from its data line. The second transistor is then rendered conductive to connect the data line to the preceding column decoder. Similarly, the data line of each preceding group is connected to the preceding column decoder with the first data line being connected to the spare column decoder.
