Title: Dynamic memory system with error correction
IPC: G11C11/406
Filed: 1981-07-23
Abstract: Refresh and initialize counter circuits included within a dynamic memory system are supplemented with additional counter control circuits for synchronizing them from the same timing source which drives the refresh and initialize counter circuits. The counter control circuits count in accordance with modulus one less than a maximum count so as to enable the information stored in each location of the memory system to be read out, corrected for single bit errors and rewritten back thereby rendering the system less susceptible to soil errors such as those produced by alpha particles. Diagnostic apparatus enables testing and verifying the operation of the soil error control apparatus. Also, the diagnostic apparatus can drive the soil error control apparatus in a high speed mode enabling the read out correction and rewriting of each location to take place within a minimum amount of time. By monitoring the status of the information being corrected, the diagnostic apparatus is able to signal whether or not the soil error control apparatus is operating properly. <IMAGE>

Title: Variable pitch propeller mechanism
IPC: B64C11/30
Filed: 1982-03-15
Abstract: The mechanism comprises a hollow shaft 1 movable in a first direction A to move the propeller blades towards coarse pitch and feather and in a second direction B to move the blades towards fine pitch. An internal axially fixed shaft 2 carries engagement elements 3 interconnected by links 8 which are pivotted to provide knuckle joint 9. The latter is acted upon by a biassing member 11 and a hydraulic piston 14 and when the pitch control means are operative, the piston 14 overcomes the bias of the member 11 thereby to displace the knuckle joint in the second direction B and to retract the engagement elements 3. When the pitch control means are inoperative e.g. due to hydraulic failure, the bias of member 11 overcomes the urging of piston 14 to extend the engagement elements 3 to a position in which their serrations 4 engage corresponding serrations on hollow shaft 1. The engagement elements 3 may be carried by the fixed shaft 2 via constraining means 6, 7 which allow movement of the hollow shaft 1 in the first direction A but prevent movement thereof in the second direction B when the engagement elements are extended. <IMAGE>
