Title: Volume-compensated low-wear reciprocating seal assemblies
Inventor: GARNJOST KENNETH D
IPC: F16J15/52
Filed: 1994-09-09
Abstract: A fluid-powered actuator (42) has a body (11) which includes an end wall (16) provided with a through-opening (21). A piston rod (44) with an inner portion (44A) arranged on one side of the end wall within a pressurizable working chamber (24) of the actuator, has a penetrant portion (44B) passing through the end wall opening, and has an outer portion (44C) arranged on the other side of the end wall. The rod is configured such that the transverse cross-sectional area of the penetrant portion is greater than the transverse cross-sectional area of the outer portion so as to define an annular surface (46) which faces away from the actuator chamber. The improvement provides a seal assembly (43) for containing fluid leaking from the actuator chamber. The seal assembly includes a sliding-seal member (30) sealingly mounted on the rod outer portion for movement therewith and for sliding movement relative thereto toward and away from the actuator surface, and a metal bellows (38) joining the body and the sliding-seal member and defining between the body, the sliding-seal member and the rod a leakage chamber (48) surrounding the end wall opening. The rod and bellows are arranged relative to one another such that equal small-amplitude movements of the rod and sliding-seal member relative to the body will not substantially change the volume of the leakage chamber. The improved seal assembly may therefore accommodate such small-amplitude movements of the rod relative to the body without causing the sliding-seal member to move relative to the rod. <IMAGE>

Patent GB-2291751-A (GB)
Title: PLL receivers
Inventor: OGORO KAZUO
IPC: H03J7/04
Filed: 1995-07-25
Abstract: In an automatic frequency control device for tuning the frequency of an intermediate frequency (IF) signal to a desired or target frequency, a reference oscillator outputs a reference oscillation signal on the basis of a control voltage from a digital/analog converter 17. A frequency measurement circuit 7 measures the frequency of the IF signal. A subtracter subtracts the frequency of the IF signal from the target frequency and thereby produces a frequency error. A multiplier 10 multiplies the frequency error by, in a proportional relation between the frequency of the IF signal and a voltage represented by a control voltage signal, the reciprocal of a gradient of the voltage of the control voltage signal to the frequency of the IF signal. An adder 12 adds the control voltage signal to the output of the multiplier, thereby correcting the control voltage signal. The digital/analog converter 17 converts the control voltage signal to an analog signal and thereby outputs the control voltage. A first memory stores a value corresponding to the desired or target IF frequency. A judgement circuit 13 determines whether output of subtractor 8 is zero. Memory 11 stores a correction factor. <IMAGE>

Title: Radiographic and fluoroscopic imaging system
Inventor: KHUTORYANSKY OSCAR
IPC: A61B6/04
Filed: 1997-11-25
Abstract: An imaging system provides rapid transition from fluoroscopic to radiographic imaging mode by maintaining the X-ray tube high voltage, increasing the filament current, allowing X-ray tube current to increase toward the desired radiographic current, and terminating exposure when the desired X-ray dose has been achieved. Rapid transition from radiographic to fluoroscopic imaging mode is provided by reducing x-ray tube high voltage to produce an equivalent fluoroscopic-level X-ray output at high initial current, dropping filament current, and enabling automatic brightness system control of the high voltage. As X-ray tube current drops, ABS correspondingly increases high voltage to maintain the desired output. The imaging system obtains movement-related information by analysing a video signal (such as from fluoroscopic image or an image from an optical camera trained on the patient), or from operator movement requests. The system uses movement-related information to control fluoroscopic pulse rate or other imaging parameters. The system can also use such information to initiate a radiographic exposure, or advance to the next step of an operator programmed examination consisting of interspersed fluoroscopic and radiographic exposures. This results in a lower dose to both the patient and the examiner, consistent with high image quality.
