Title: Process and apparatus for reducing the cross-section of elongate material, such as hot continuously cast material
Inventor: WIEDEMER KARL
IPC: B21B1/02
Filed: 1986-02-24
Abstract: In the described process for reducing the cross-section of hot continuously cast materials by intermittent rolling, gradual rolling forces act in the individual rolling phases on the rolling material which is moved forwardly in a stepwise manner and progressively rolled. A rolling mill for carrying out the process has rolls 4a and 4b with grooves for progressive reduction in cross-section, which are disposed in a movable carriage (2, Fig. 6) driven as by a crank (3a). The rolls are rotated by gears (6a) or sprockets engaging stationary racks or chains. That makes it possible to achieve a reduction in cross-section of up to about 90 to 95% in one rolling mill pass. The rolls may define two passes (15, 16, Fig. 2) between which the material (5) is moved by axial movement of roll 4a. <IMAGE>

Title: Fluid transfer device
Inventor: SCHULZE WALLACE MILTON
IPC: F01D25/18
Filed: 1990-01-11
Abstract: An aircraft gas turbine engine has a main oil system 11 and an auxiliary oil system 13 connected by a device 10 which allows intermittent topping up of the system 13 by transferring oil from system 11. When the engine is running, the oil pressure closes valves 25 and 101 which prevents any oil transfer, but aperture 47 in valve 25 allows oil to fill reservoir 65, pushing diaphragm 67 to the right. When the engine stops, springs 49 and 123 return the valves to positions where they contact seats 43 and 119, while spring 71 expands to discharge the contents of reservoir 65 into system 13 past valve 25. Any excess oil returns from system 13 to system 11 past valve 101. Filters 19 and 88 in the transfer and return lines prevent transfer of solid contaminants between the two systems.

Title: Phase jitter correction arrangement
Inventor: CUPO ROBERT L
IPC: H04L1/20
Filed: 1991-07-25
Abstract: In a communications system, a transmitted signal is typically impaired by phase jitter attributed to power line harmonics and ringing voltages present in a communications channel (103). In order to properly recover the transmitted signal, the phase jitter in a received signal needs to be eliminated. To this end, an infinite-impulse-response (IIR) filter arrangement (70) is employed in a receiver (102) to estimate the phase jitter and is followed by a demodulator (35) which substantially removes the jitter based on the estimate. The transfer function of this IIR filter arrangement is a function of the autocorrelation of a phase error, the latter being indicative of the difference between the phase jitter in the received signal and the jitter estimate. <IMAGE>
