Abstract: A thimble tube (24) for use in a fuel assembly guide tube (12) in a nuclear reactor is an elongate hollow tube having one end closed. A portion of the tube (24) that extends into the reactor is formed from a plurality of sections (26, 28) attached to each other to form the tube in an alternating fashion along the width and length of the tube. The sections (26, 28) are formed from materials having different coefficients of thermal expansion to cause the thimble tube (24) to warp into supporting contact with the interior of the guide tube (12) at normal reactor operating temperature.

Abstract: In digital data transmission and storage, binary data strings are encoded into symbols from a quaternary alphabet by a specific inventive use of finite-state machines. The novel, high-rate quaternary codes offer spectral shaping properties together with a significant increase in noise margin when used on channels which lend themselves to partial-response shaping. In principle, the encoding occurs in three steps: a u-state transition diagram (fig 2 ) generates quaternary symbols whose running digital sum assumes values from a given set; the u-state transition diagram is converted into a v-state machine (fig 3) each of the v states being associated with a number of transitions sufficient to encode the input data bytes into output code words; finally, the v-state machine is switched into a next state depending on its current state and the last encoded input data byte.

Abstract: The invention proposes a fluid pressure operated actuator (10) in which the directional control valve (13) controlling the actuator (10) is attached externally via a flange plate (12). As a casing, the actuator (10) has a cylinder barrel (11) designed as a special section tube, arranged in a uniformly distributed manner on the outer circumference of which are four profiled longitudinal struts (22 to 25) extending parallel to the longitudinal axis and to one another. The flange plate (12) is guided in axially displaceable and radially captive fashion on two (22, 23) of the longitudinal struts, these longitudinal struts (22, 23), which are hollow, forming ducts (36, 38) for the pressure fluid, via which the pressure-fluid connections lead to the pressure spaces (18, 21) on both sides of the piston (15). The actuator (10), which is of compact construction, requires few parts to carry the pressure fluid, thereby reducing the risk of the escape of leaking pressure fluid. <IMAGE>

Abstract: A method and apparatus are described for increasing engine braking, when a crankcase scavenged two-stroke engine (10) is operated in a deceleration fuel cut-off mode. In response to the detection of operating conditions indicating engine operation in the deceleration fuel cut-off mode, the quantity of air inducted into the engine (60) is decreased, for a predetermined period of time. After this period of time elapses, the quantity of air inducted into the engine (10) is then increased. This is preferably accomplished by regulating the degree of opening of a throttle valve (24) disposed within the engine air intake system (22). The initial closing of the throttle valve (24) restricts air flow through the engine (10) for a predetermined time, to maintain efficient catalyst operating temperatures in the engine exhaust system. During extended operation in the deceleration fuel cut-off mode, the throttle valve (24) is opened, after the lapse of the predetermined time, to increase the quantity of air inducted by the engine (10). This results in increased engine braking, due to the additional work that must be performed in compressing the larger quantity of inducted air.
